Reviews and syntheses: Current perspectives on biosphere research – 2024
Abstract. This review of recent advances in biosphere research aims to provide information on selected issues related to changes in biodiversity, ecosystem functioning, social and economic interactions with ecosystems, and the impacts of climate change on the biosphere. We highlight advances on nine themes that have been recently published in peer-reviewed journals that are gaining importance in the scientific community and have the potential to guide future actions as well as inspire future research questions. Our focus is on the interactions between climate, biosphere and society, and on strategies to sustain, restore or promote ecosystems and their services. While mitigating climate change is expected to reduce many risks and associated costs, rapid emission reductions are also crucial to secure various co-benefits of ecosystems, such as coastal protection or stabilization of regional hydrological cycles. In this context, conservation measures implemented in cooperation with local actors are key to efficient resource allocation. At the same time, holistic action frameworks at the global level are required to guide and support such efforts.

RC1: 'Comment on egusphere-2024-2551', Emma Hauser, 05 Oct 2024
In the manuscript Reviews and syntheses: Current perspectives on biosphere research--2024, the authors propose that, given the speed at which climate reports are generated and lack of interdisciplinary efforts, the scientific and policy communities need a method to more frequently synthesize the latest biosphere research across disciplines. The authors employ an example survey method and present a review of their findings, which include a set of nine emergent and pressing challenges in ecological research. The goal of this work is to synthesize the latest policy-relevant research and inform interdisciplinary collaborations to arrive at creative, whole-picture solutions to ecological challenges.
This is a useful concept and one that I think could more rapidly advance Earth systems research, as well as improve our tools for addressing climate change. I do wonder if the emphasis on including almost exclusively recent works might exclude issues that have accumulated a large body of work over time but that still have advances in recent years, ultimately reducing some continuity in addressing climate challenges. For example, I was surprised that some topics, like changing carbon cycle dynamics or fossil fuel consumption, weren’t given a section of the report, although the authors note their importance as a top priority for mitigating climate change in the introduction. It’s possible those topics weren’t singled out because they were either meant to be woven throughout the sections, or that this paper is meant to be complementary to other documents like IPCC reports or the Global Carbon Budget where that is the emphasis. Either way, I think the authors could make this intent clearer up front. I ultimately wished for more of a conclusive statement of implications in both the introduction and conclusion detailing the novelty of the synthesis and its suggested action steps, as well as the role of this sort of survey in making ecological advances. Including this text might also help highlight broader issues that were not specific sections of the article but that are critical steps for addressing ecological challenges.
It does seem like there is a slightly different authorial voice in some of the sections, as though different sections were written by different people, which makes some of the sections fit together differently than others (for example some sections include a statement of the problem/question in the ‘Background’ subsection, while others do not and include the problem only in the ‘Challenges’ subsection). Some sections are also much longer, and although I don’t think any of the sections are meant to be emphasized more than another, it does have the effect of giving the policy sections a bit more weight. I think it might be helpful to trim the sections a little so that they are more consistent formats and lengths. This might also improve some of the repetitiveness that developed in the later sections of the article. The last 4 sections especially (3.6-3.9) seem to have a lot of overlap and I wonder if there could be different ways to merge some of these ideas that could also reduce the length. Maybe these last sections could be reorganized into a section on biodiversity and conservation, a section on social ecological challenges and inclusivity, and a section on directions for science policy and economics. Alternately, sections 3.7 and 3.8 seem to pose oppositional ideas about including ecosystems in social-economic frameworks and I wonder if merging these sections to highlight the controversy growing in this area might be a way forward. Sections 3.6 and 3.9 also feel quite similar so may be able to be merged. I do think it’s important to highlight that these themes are interconnected as the authors have done, which ultimately means some ideas may be reiterated, but I think there may be ways to trim the text that maintains the spirit of that idea while still making the final sections more distinct.
A final thought for the authors to take or leave--it could be nice to conclude with some sort of conceptual figure that ties all the sections together. Something demonstrating the type of local to global collaboration and action needed across different sectors and disciplines to address specific challenges would be nice. I don’t think this is absolutely necessary but would be great to make the sections feel a bit more cohesive and give the reader a visual overview about how all these parts fit together.
Overall I do think this is a nice summary of many emerging biosphere topics, and the methodology used by the authors, especially if they are able to continue expanding the reach of their solicitation, could be a useful way to identify key areas where research and policy advances are needed.
Section and line specific comments are included below.
Abstract:
Line 3: At the start of the abstract it would be great to add a little detail about the methodology since it seems like that is an important part of what the authors are trying to test as a strategy for generating a report.It would be great if the authors could include an overarching sentence at the end of the abstract stating why the review is important.
Intro:
Line 2: Changes should be changed. First sentence is a little awkward.Line 20: natural processes
Paragraph starting line 45: This seems like information that should have been included in the previous paragraphs when the IPCC reports are introduced. I see how the authors are trying to use it to lead into the idea that these reports are not interdisciplinarily integrative, but if the paragraph stays here, the authors need to make that point more explicit in this paragraph.
Line 53: The authors note here that there is a lack of integrative reporting on the biosphere but I’m not sure the previously stated information convinces me of that entirely, as written. It may be the case for the reports included in the previous paragraph, but could the authors give some explicit examples there?
The final paragraph of the introduction feels a little more like a conclusion. I wonder if this paragraph could be removed or changed to refocus on the idea started in line 75 about climate mitigation and carbon emissions to detail how this overarching concept is woven throughout the 9 key topics.
Methods:
It would be nice to have a little more specific criteria about how these 9 proposal topics were judged and selected aside number of citations of recent literature. Was there a rubric for selection?Insights:
3.1 Coastal habitats
Line 127: Breaking up this sentence would make the ideas presented clearer.Lines 126-137: This paragraph seems more solutions oriented rather than a description of challenges. Possibly move to the next section?
Line 157-159: This short paragraph seems a little out of place. Maybe it could be merged with the previous paragraph?
3.2 Forests and precipitation
The background highlights the important water cycling functions of forests but doesn’t state the question/problem. This might be okay, but other sections do state the problem in the background so it would be nice to make them more consistent.Lines 217-219: The authors note here that evidence is mounting so it seems like it might be important to have multiple references to support the claim, especially since the next sentence notes that, despite this evidence, the effect is not observed in the tropics.
Line 221—I don’t follow this sentence “This suggests that …elsewhere.”
Line 230: “Therefore, also…” is a little odd grammatically. Maybe take out the word “also”?
Line 241: Extra parentheses are included here that aren’t needed.
Line 245: The wording and use of colon here is a little awkward. I think I would switch to “Reforestation has larger effects on several areas of the globe” and leave out the colon (or something along those lines).
Line 235/246: I follow the use of the tipping point term that the authors use in both locations, but the description is somewhat vague. It would help to be explicit what you mean here—maybe “a tipping point at which a forest transitions to a dryland or grassland due to decreased moisture”?
3.3 Fire risks
Line 284: Parenthesis needed before Copernicus rather than after.3.5 20-25% natural habitat in modified landscapes
This section ultimately posits a divide between humans and nature. The following sections discuss the inclusion of humans in nature and recognizing the intrinsic value of the natural world. It might be useful to have some text that discusses these different ways of viewing nature and their relevance to how we make scientific and policy decisions.Line 472: Is there any indication that the spatial arrangement matters? For example, does each individual square kilometer need to be 20-25% natural habitat (so habitat patches) or if you have 2 square kilometers of land but the natural habitat for both is all shifted all to one side in a continuous tract does that achieve the same result? I’m not sure whether there’s an answer but just curious.
Line 490: Missing a parenthesis
3.6 Comprehensive policy packages
The background to this section is much more extensive than the others and states many of the problems upfront while other sections are not organized this way. It would be great to be more consistent between sections.Line 538-543: This part feels like it belongs in the ‘Offering solutions’ section.
This section has a lot more detail than the others and it feels like there is more focus here. It might be helpful to trim or to move to the end and merge with section 3.9, which seems quite similar.
3.7 Convivial conservation
This section also reads as if written by a different author.I wonder if the list of principles outlining convivial conservation could be edited to a summary paragraph that states the main intent, or one sentence per bullet point. This seems a little over-detailed, especially as one of 9 sections.
3.8 Increasing social economic value of ecosystems
Line 725: This section seems to be in direct conflict with the previous section’s suggestions that we do not use capitalist frameworks to analyze ecologic value. Could the authors address this conflict more completely? It seems like these differing ideas should be discussed, or that these two sections could be one section that describes the current debate and ways forward with it.3.9 Biodiversity governance
774: Earth dominating is kind of a strange term. Maybe something else? Could also be removed and the sentence would still work.The background text for this section is a little vague. It relies heavily on knowing the details of the Montreal Global Biodiversity Framework. It would be great if the authors could add a bit more detail about what specific steps might prioritize the GBF.
788: Here the authors state “as for example in Switzerland…” but do not go on to describe the example and detail how it demonstrates the concept described here. This example should be outlined in more detail as should the “larger scale mechanisms” at the end of the sentence.
Conclusions
Line 843: cycle needs an s at the end.Is there a reason why some words from lines 850-878 are in bold text? If so, could that be made clearer?
Line 850: If the idea here is synthesizing the latest science that has been missed by groups like the IPCC and generating new ideas/solutions, it seems a little odd to me that the primary conclusion is so similar to that which is currently the emphasis of these major organizations. This can be an important point—maybe the authors should emphasize, as proposed by the latest IPCC reports, this 1.5 degrees needs to be our major focus—but presenting it as something new or different seems a bit misleading. It would be great to have a statement of what’s new from this synthesis or, alternatively, if this backs up findings from other reports, that should be emphasized.
Line 868: This seems like something that maybe could be a focus—the need to improve monitoring and quantification metrics. Based on the presented focus areas, how do the authors propose to do so and what specific metrics would they like to see?
The conclusion paragraphs starting on like 878 are less repetitive/summary type paragraphs and I wonder if the conclusion could be paired down to focus on these rather than spending as much time on summarizing what was written previously.

Thank you for your constructive and supportive review. Your feedback is invaluable in helping us to communicate our key messages more effectively and to achieve a clearer, more balanced synthesis of the content.This is a useful concept and one that I think could more rapidly advance Earth systems research, as well as improve our tools for addressing climate change. I do wonder if the emphasis on including almost exclusively recent works might exclude issues that have accumulated a large body of work over time but that still have advances in recent years, ultimately reducing some continuity in addressing climate challenges. For example, I was surprised that some topics, like changing carbon cycle dynamics or fossil fuel consumption, weren’t given a section of the report, although the authors note their importance as a top priority for mitigating climate change in the introduction.

Either way, I think the authors could make this intent clearer up front.
We aimed to focus with this paper on recent insights related to the biosphere. Hence drastically reducing fossil fuel consumption - essential for fighting climate change - is not topic of this paper, although this of course is key to addressing biodiversity loss. We will rewrite several sentences in the introduction to make this clearer.
However we will mention in the revised manuscript the long standing insights documented in IPCC and IPBES assessments and other reports in the background sections where it is appropriateI ultimately wished for more of a conclusive statement of implications in both the introduction and conclusion detailing the novelty of the synthesis and its suggested action steps, as well as the role of this sort of survey in making ecological advances. Including this text might also help highlight broader issues that were not specific sections of the article but that are critical steps for addressing ecological challenges.
We will revise the text to better reflect the purpose of this manuscript in the introduction: With this study, we aim to raise awareness of the various challenges within the biosphere and their interconnectedness with other crises within the Earth system, provide synergistic strategies to address complex challenges, and stimulate future research questions.
We will revise the discussion to include findings on integrated decision making, land management strategies, measurement and knowledge generation, and link them to species and climate change objectives.It does seem like there is a slightly different authorial voice in some of the sections, as though different sections were written by different people, which makes some of the sections fit together differently than others (for example some sections include a statement of the problem/question in the ‘Background’ subsection, while others do not and include the problem only in the ‘Challenges’ subsection).
Some sections are also much longer, and although I don’t think any of the sections are meant to be emphasized more than another, it does have the effect of giving the policy sections a bit more weight. I think it might be helpful to trim the sections a little so that they are more consistent formats and lengths. This might also improve some of the repetitiveness that developed in the later sections of the article.
Thank you very much for your suggestions to streamline the manuscript. We will make the following revisions to harmonise the topic sections:
- Each section will be limited or expanded to about 1500 words.
- The background sections will be revised to create a seamless transition from the introduction without redundancy.
- We will improve the challenge sections with clear problem descriptions and ensure coherence with the solutions presented later.
- General recommendations will be avoided in the solution sections.
- For certain topics, we will increase the number of citations to provide a more comprehensive overview of each topic.
- Finally, a core team will review and polish the text to ensure consistency and cohesion.
The last 4 sections especially (3.6-3.9) seem to have a lot of overlap and I wonder if there could be different ways to merge some of these ideas that could also reduce the length. Maybe these last sections could be reorganized into a section on biodiversity and conservation, a section on social ecological challenges and inclusivity, and a section on directions for science policy and economics. Alternately, sections 3.7 and 3.8 seem to pose oppositional ideas about including ecosystems in social-economic frameworks and I wonder if merging these sections to highlight the controversy growing in this area might be a way forward. Sections 3.6 and 3.9 also feel quite similar so may be able to be merged.
I do think it’s important to highlight that these themes are interconnected as the authors have done, which ultimately means some ideas may be reiterated, but I think there may be ways to trim the text that maintains the spirit of that idea while still making the final sections more distinct.
Thank you very much for your suggestions to re-organise this section and to reduce overlap. We plan to refine the focus of each section to improve clarity, reduce overlap and highlight the interconnectedness. More specifically, we intend the following changes:
- Section 3.6 will focus on holistic policy packages at national and international levels.
- Section 3.7 will focus on the principles of local solutions and inclusive, convivial nature conservation.
- Section 3.8 will analyse the societal value of ecosystems.
- Section 3.9 will be integrated with the previous sections and the revised discussion.
The aim of this reorganisation is to improve the coherence and thematic focus of the topics while maintaining the links between them.
A final thought for the authors to take or leave--it could be nice to conclude with some sort of conceptual figure that ties all the sections together. Something demonstrating the type of local to global collaboration and action needed across different sectors and disciplines to address specific challenges would be nice. I don’t think this is absolutely necessary but would be great to make the sections feel a bit more cohesive and give the reader a visual overview about how all these parts fit together.
Thank you very much for this suggestion. We already have some ideas on how to realise a guiding graphic.
Overall I do think this is a nice summary of many emerging biosphere topics, and the methodology used by the authors, especially if they are able to continue expanding the reach of their solicitation, could be a useful way to identify key areas where research and policy advances are needed.
Thank you very much for these motivating final words and for your valuable suggestions to improve the manuscript.

We will revise the text based on your helpful and constructive comments. Thank you for your support.Friedrich Bohn on behalf of all co-authors.

This manuscript reviews the literature and provides current perspectives on biosphere research from 2021-2024, using an interdisciplinary perspective. They point to similar reviews of other topics (e.g., top 10 topics in climate change) to justify their approach. They also argue that the slow pace of large-scale international reports (e.g., IPCC’s assessment reports) necessitates periodic reviews such as theirs to provide policy relevant information. The goals and objectives of the manuscript are ambitious and laudable, and there are interesting aspects of the synthesis. I feel there is value in the study.
Now, if I put on my critical reviewer hat and really embody the dreaded “reviewer 2” … I felt this was very underbaked. I think this manuscript suffers from the “Frankenstein” effect, in that the sections that comprise the synthesis have just been copied and pasted together by the various section leads, without any polishing or alignment between them. Some sections are roughly double the length of others. There is extensive repetition of information in the latter half of the article. There are also many instances in which boilerplate sentences occur in the latter half of the article, which really do not need to be there. Some of the sections have thoughtful solutions and recommendations that cover a wide base of the challenges, whereas others have extremely cursory recommendations that largely recommend some of the authors’ own views. For example, the NCS implementation risk only provides one suggestion – use tonne-year accounting – which one of the authors has published extensively on, without noting the many studies that have pointed out potential issues with this method. There is also no discussion of the many other challenges associated with NCS implementation (additionality, leakage, environmental justice concerns, financing, non-carbon climatic effects, etc.). Many of the sections also present solutions and recommendations that do not relate to the challenges presented. The result is that for many of the sections, the “emerging topics” that are presented feel surface-level and underdeveloped.
I have five major suggestions to improve this manuscript:
- Identify a subset of the authors (perhaps 1-3) to read through all sections and edit heavily. The paper is very lengthy, and unfortunately today, folks tend to have limited time/energy to read lengthy papers. I would suggest establishing a word limit or some sort of agreement in terms of the maximum length of sections. This subset of coauthors could read for several things: 1. Is the background of each topic area relevant and necessary, or is it simply repeating elements of the introduction? 2. Do the proposed solutions and recommendations directly address the challenges identified? Similarly, are they specific enough to actually provide novel insight on the topic, or are they overly general (e.g., “develop policy to solve this”). 3. Decide what the purpose of the recommendations section is. Some sections just have cursory bullets, others have thoughtful paragraphs with specific examples. Perhaps these recommendations sections are not needed (see point 3).
- Alternatively, consider rewriting each section to identify one key insight from each topic area. Rather than providing a mini-review of all challenges and trying to highlight multiple solutions and recommendations, pick one insight (ala the Martin et al. 10 insights for climate science piece you reference). I think this would help prevent the reader from feeling like the authors have left out many important areas – as they will expect that you will not address all areas from the beginning. This would also allow you to greatly condense the article and be much more focused. Indeed, the section titles already somewhat suggest this insight – the supporting text just needs to be further developed to more succinctly justify the insight.
- Provide some sort of synthetic thinking across the 9 subject areas. The discussion currently just provides one or two key points from each section, but no synthetic thinking is provided in terms of cross-cutting themes or key areas of research that could address multiple challenges. One suggestion is that rather than providing recommendations (which are typically just bullet points that repeat the information in the solutions section), remove the recommendations and provide a synthetic analysis in or before the discussion… or perhaps compile the recommendations for each topic in some sort of table. For example, support for increased autonomy of Indigenous and local communities was a common solution – and thus drawing out this theme across the topics could be valuable for your intended audience to see.
- Provide more details and information on the actual data collection / whittling of ideas down in supplementary information. As I mention above, I am not convinced that all sections sufficiently address emerging trends across each topic. I know it is impossible to cover everything, but there appears to be a bias towards the work of the coauthors for several of the topics. There should be more transparency in how these topics were arrived at, given that they might influence future policy, research, action, etc.
- Alternative to all the above – and this would involve a massive overhaul of the manuscript – I feel the 9 sections could actually be supplementary information themselves, and some sort of synthetic distillation of everything in a much shorter manuscript could be written. This would likely provide a much more impactful and meaningful article. You might also consider adding conceptual figures or tables to better convey the information in a much more concise and digestible fashion.
There are also some instances of oversimplification of topics that have the potential to be misused in the recommendations (e.g., “NCS should prioritize reforestation of mangroves”). I work extensively in mangroves and am very partial to these ecosystems – but the field generally believes that conservation of existing natural forests should be prioritized before reforestation; and who is to say that mangroves should be prioritized over other ecosystem types?
It's also worth noting that there are extensive typos and many instances of awkward grammar. Given the accomplishments of the author team, I expected more professionalism in the preparation of the manuscript.
Minor suggestions:
Line 28 – some awkward language; reads as though IPCC & IPBES are “international negotiations,” which they aren’t.
Line 40 – There is a working assumption that IPCC and IPBES are what those implementing biosphere stewardship primarily respond to. Do you have any evidence for that? There are also many other scientific publications that are released (e.g., the annual Global Carbon Budgets) and many land management agencies I think are less tied to these high level reports (thinking of the US Forest Service, which uses national level data and policies).
Line 47 – There is also the “scientists’ warnings” series / community.
Line 53 – How are you defining “biosphere”? IPCC and IPBES include many scenarios that incorporate social and economic trajectories. The planetary thresholds group out of PIK also does lots of similarly themed research, so I’m not sure I buy the idea that this is unaddressed.
Line 68 – Doing my duty as a critical reviewer … I am not sure any of this is novel or an emerging theme. I think it’s clear that biodiversity loss, land degradation, chemical pollution, etc., are all interlinked and driven by social and economic systems.
Line 81 – missing a space before “In the future”
Line 150 – awkward phrasing - “and result in improved”
Section 3.1
Section 3.1.3 – I find this section to be rather abstract, with the solutions space disconnected from the challenges. I agree with the statement that inclusive approaches are a must, but think there is a logical disconnect between how community engagement in restoration is likely to alleviate issues such as coastal squeeze.
Line 175 –unclear/imprecise. Do you mean physical space? Or metaphorical? Stewardship is governance, so I don’t really know what providing hectares for governance means?
Line 177 – Indigenous is typically capitalized as a sign of respect; would recommend this throughout your manuscript.
Line 181 – This statement is very problematic and has great potential to be misused. When designing NBS for CC, there are many other solutions that should be prioritized over mangrove reforestation (e.g., conservation of existing biodiverse mangroves, or providing them accommodation space). I agree with the article’s main argument (that mangrove reforestation is more effective than afforestation), but this bullet point does not capture that at all. Suggest deleting or clarifying.
Section 3.2
Line 222 – Awkward grammar in this paragraph.
Line 241 – empty parentheses
Section 3.2.3 – Is restoring forests, which takes many decades and is extremely limited in terms of spatial footprint, really the solution to the issue of a positive feedback loop between deforestation & increased drought-driven forest loss / degradation? To me, the solution is to halt deforestation before you think about reforestation. The best way to do this is likely through strengthened environmental governance, whether through policies, monitoring, enforcement, more resources, or voting folks into power that care about the issue. You might consider whether reforestation and afforestation should be the focus of this section – or whether it should be more focused on strengthening efforts to halt deforestation (is there any evidence to show restored forests help with water cycling in expansive tropical forests)?
Line 243 – citation? Is this based on modeling in which you have fully restored forests, or empirical data in which forests take many decades to recover structure and canopy cover?
Line 265 – So protecting Amazonian forests from deforestation is not a priority? We have seen massive droughts across the Amazon this year, might consider rephrasing this.
Line 275 – Critical in what sense?
Section 3.3
Line 285 – pulling in opposite directions but regionally distinct, correct? Or are these patterns generally occurring in the same locations?
Line 291 – Interesting – this is a surprising result to me, particularly given the massively extensive fires in the boreal region last year. Also occurrence is rather imprecise. Do you mean extent of fire? Or frequency? Is the general pattern that we are getting fewer but more intense fires across the globe? And this is specific to forests? Or grasslands as well?
Line 318 – This pattern of reduced area of burns with increasing fire conditions sounds like what the US implemented for 100 years and is part of what is now driving catastrophic high-severity fires. I.e., you don’t burn areas that normally burn, fuels build up over decades, and then the climate gets to a point such that all of your accumulated fuels go up in flames at once. There are many fire studies that argue we should rethink our relationship with fire, and start with the fire ecology of the system. (i.e., suppression might not be a great solution).
Line 322 – The U.S. is being MASSIVELY impacted by severe fires – surprised that you find economically developed societies are less affected.
Line 325 – Why not start this solution paragraph with recommending developing an understanding of the fire ecology of the system, and locally adapting strategies and tools for fire management to that system (whether they be suppression, Rx fire, forest types, etc.).
Section 3.3.4 – These are good recommendations.
Section 3.4.
Line 359 – This might be misleading. Terrestrial ecosystems have absorbed a roughly consistent proportion of our annual emissions for several decades but it is due to a mixture of effects – CO2 fertilization is a big one, but also lengthened growing seasons in northern latitudes, and regrowth of forests in northern / developed countries have contributed. I wouldn’t note the Co2 fertilization effect unless you are talking about the fact that terrestrial ecosystems have uptaken roughly the same percentage of our annual emissions over many decades. I also wouldn’t use “additional” removal as additionality has a very specific meaning within Nature-based CDR.
Line 3.4.3. – There are many critiques of tonne-year accounting, and also many other potential solutions to NCS implementation (citing projects in areas where disturbance is less likely, designing solutions to confer resilience to ecosystems, focusing on strategies that might be less prone to disturbance such as agroforestry, etc.). This section feels cursory and under-developed relative to the others. I am also not sure that treating NCS as temporary resolves all implementation risks (thinking about issues related to additionality, leakage, environmental justice, etc. – it only addresses the permanence criteria).
Section 3.5.
This section is well-developed and the logic is consistently threaded through the various sub-sections nicely (background – challenges – solutions – recommendations). In the interest of pushing the authors further, wouldn’t there be unique challenges to restoring 25-30% of every developed square kilometer (this seems massively expensive). What are those social and economic barriers, and do you have concrete ideas for how to work past them?
Section 3.6
This feels like a large enough topic to encompass all other topics covered in this manuscript – is there a way to make this section more focused?
Lines 495-510 – I suggest deleting or condensing this. This section feels longer than the others, and I don’t think this broad framing is needed given the article’s intended audience.
Line 540 – Would this paragraph be better placed in solutions? E.g., reframe policies section to “design policies to transition to a circular economy”
Line 565 – I really like these examples as they provide concrete guidance on policy recommendations, which is lacking in many other sections. However, some of this can be condensed (e.g., you already describe the CBD and other agreements in the intro). Consider focusing the sentence more towards solutions (e.g., keep the sentences on how international agreements can be improved).
Line 605 – I like these recommendations. However, the author team should align the recommendations. Most are just a line or two, whereas these are fleshed out with examples. You might consider condensing these down to pithy recommendations.
Section 3.7
Line 630 – Could delete or rewrite the boilerplate first sentence.
Line 635 – Love that you are bringing political ecology into this. So critical for many of the issues that are highlighted in this article. I think it also adds credence to the interdisciplinarity claims of the article.
Discussion
I am not sure how useful the 2-3 sentence highlights of the 9 topics actually is. Surely, given that you are focused on interconnections across biosphere stewardship, there are synergies across the nine sections. What are those? Can you provide us with some sort of synthetic view or key themes that emerge across all of the areas? This would be most helpful for the policy-makers, environmental stewards, and researchers that you suggest are the audience of this article.

Thank you for your supportive and critical feedback, which is very helpful in improving the manuscript. We appreciate the time you have taken to critically review our manuscript, your insights and the detailed feedback you have provided. We will implement your suggestions, as well as those of reviewer 1, throughout the manuscript.
Now, if I put on my critical reviewer hat and really embody the dreaded “reviewer 2” … I felt this was very underbaked. I think this manuscript suffers from the “Frankenstein” effect, in that the sections that comprise the synthesis have just been copied and pasted together by the various section leads, without any polishing or alignment between them. Some sections are roughly double the length of others. There is extensive repetition of information in the latter half of the article. There are also many instances in which boilerplate sentences occur in the latter half of the article, which really do not need to be there. Some of the sections have thoughtful solutions and recommendations that cover a wide base of the challenges, whereas others have extremely cursory recommendations that largely recommend some of the authors’ own views. For example, the NCS implementation risk only provides one suggestion – use tonne-year accounting – which one of the authors has published extensively on, without noting the many studies that have pointed out potential issues with this method. There is also no discussion of the many other challenges associated with NCS implementation (additionality, leakage, environmental justice concerns, financing, non-carbon climatic effects, etc.). Many of the sections also present solutions and recommendations that do not relate to the challenges presented. The result is that for many of the sections, the “emerging topics” that are presented feel surface-level and underdeveloped.
Thank you very much for your suggestions to streamline the manuscript, and the recommendations for improving the structure to hone in on the most pertinent messages.
I have five major suggestions to improve this manuscript:
- Identify a subset of the authors (perhaps 1-3) to read through all sections and edit heavily. The paper is very lengthy, and unfortunately today, folks tend to have limited time/energy to read lengthy papers. I would suggest establishing a word limit or some sort of agreement in terms of the maximum length of sections. This subset of coauthors could read for several things: 1. Is the background of each topic area relevant and necessary, or is it simply repeating elements of the introduction? 2. Do the proposed solutions and recommendations directly address the challenges identified? Similarly, are they specific enough to actually provide novel insight on the topic, or are they overly general (e.g., “develop policy to solve this”). 3. Decide what the purpose of the recommendations section is. Some sections just have cursory bullets, others have thoughtful paragraphs with specific examples. Perhaps these recommendations sections are not needed (see point 3).
Thank you very much for these suggestions that are very helpful in highlighting the key messages we want to convey. We will revise the manuscript by undertaking the following steps
- Each section will be limited or expanded to about 1500 words.
- The background sections will be revised to create a seamless transition from the introduction without redundancy.
- We will improve the challenge sections with clear problem descriptions and ensure coherence with the solutions presented later.
- General recommendations will be avoided in the solution sections.
- Finally, a core team will review and polish the text to ensure consistency and cohesion
- Alternatively, consider rewriting each section to identify one key insight from each topic area. Rather than providing a mini-review of all challenges and trying to highlight multiple solutions and recommendations, pick one insight (ala the Martin et al. 10 insights for climate science piece you reference). I think this would help prevent the reader from feeling like the authors have left out many important areas – as they will expect that you will not address all areas from the beginning. This would also allow you to greatly condense the article and be much more focused. Indeed, the section titles already somewhat suggest this insight – the supporting text just needs to be further developed to more succinctly justify the insight.
We prefer to follow your first suggestion and still take some elements from this second point to improve focus and clarity:
- We will clearly state that this list is not exhaustive and that future publications will cover additional topics, as we plan to publish this type of paper on a regular basis (probably annually).
- We will also streamline and refine the longer sections, removing repetition to eliminate excessively long passages, so that each topic remains concise and focused.
- Provide some sort of synthetic thinking across the 9 subject areas. The discussion currently just provides one or two key points from each section, but no synthetic thinking is provided in terms of cross-cutting themes or key areas of research that could address multiple challenges. One suggestion is that rather than providing recommendations (which are typically just bullet points that repeat the information in the solutions section), remove the recommendations and provide a synthetic analysis in or before the discussion… or perhaps compile the recommendations for each topic in some sort of table. For example, support for increased autonomy of Indigenous and local communities was a common solution – and thus drawing out this theme across the topics could be valuable for your intended audience to see.
Thank you for this valuable suggestion for a more synthetic discussion. We will revise the discussion section, restructure the synthesis section, and organise our recommendations around the following key themes: improving inclusive decision-making, advancing land management strategies, improving measurement and knowledge generation, and linking these findings to the goals of species conservation and climate change mitigation.
- Provide more details and information on the actual data collection / whittling of ideas down in supplementary information. As I mention above, I am not convinced that all sections sufficiently address emerging trends across each topic. I know it is impossible to cover everything, but there appears to be a bias towards the work of the coauthors for several of the topics. There should be more transparency in how these topics were arrived at, given that they might influence future policy, research, action, etc.
Thank you for sharing your considerations. To better address how the topics covered were selected, we will work on the following points:
- We will include an appendix with the questionnaire used in our study and revise the methods section.
- For some topics we will increase the number of citations to provide a more comprehensive representation of different perspectives in each area.
- As mentioned earlier, we will emphasise that this collection does not claim to be comprehensive and absolute. Rather, it is our intention to publish this type of work on a regular basis, ideally annually.
- Alternative to all the above – and this would involve a massive overhaul of the manuscript – I feel the 9 sections could actually be supplementary information themselves, and some sort of synthetic distillation of everything in a much shorter manuscript could be written. This would likely provide a much more impactful and meaningful article. You might also consider adding conceptual figures or tables to better convey the information in a much more concise and digestible fashion.
Thank you very much for sharing your conceptual ideas on how to approach a manuscript such as ours that provides an overview over the current issues in biosphere science. As this project is planned to be repeated annually, we will seriously consider these suggestions for the next paper in this series. We will develop a conceptual figure. However, for the current manuscript, we will skip this alternative route in order to publish the paper as soon as possible.
There are also some instances of oversimplification of topics that have the potential to be misused in the recommendations (e.g., “NCS should prioritize reforestation of mangroves”). I work extensively in mangroves and am very partial to these ecosystems – but the field generally believes that conservation of existing natural forests should be prioritized before reforestation; and who is to say that mangroves should be prioritized over other ecosystem types?
We will adapt this statement and carefully review others.
It's also worth noting that there are extensive typos and many instances of awkward grammar. Given the accomplishments of the author team, I expected more professionalism in the preparation of the manuscript.
We will carefully edit the manuscript to remove any awkward grammar and typos.We will also revise the text based on your helpful and constructive minor suggestions.
Thank you very much for your assistance in improving this manuscript. Although you consider yourself as being the “dreaded reviewer2”, we found your comments very constructive and helpful in improving the manuscript.

RC1: 'Comment on egusphere-2024-2551', Emma Hauser, 05 Oct 2024
In the manuscript Reviews and syntheses: Current perspectives on biosphere research--2024, the authors propose that, given the speed at which climate reports are generated and lack of interdisciplinary efforts, the scientific and policy communities need a method to more frequently synthesize the latest biosphere research across disciplines. The authors employ an example survey method and present a review of their findings, which include a set of nine emergent and pressing challenges in ecological research. The goal of this work is to synthesize the latest policy-relevant research and inform interdisciplinary collaborations to arrive at creative, whole-picture solutions to ecological challenges.
This is a useful concept and one that I think could more rapidly advance Earth systems research, as well as improve our tools for addressing climate change. I do wonder if the emphasis on including almost exclusively recent works might exclude issues that have accumulated a large body of work over time but that still have advances in recent years, ultimately reducing some continuity in addressing climate challenges. For example, I was surprised that some topics, like changing carbon cycle dynamics or fossil fuel consumption, weren’t given a section of the report, although the authors note their importance as a top priority for mitigating climate change in the introduction. It’s possible those topics weren’t singled out because they were either meant to be woven throughout the sections, or that this paper is meant to be complementary to other documents like IPCC reports or the Global Carbon Budget where that is the emphasis. Either way, I think the authors could make this intent clearer up front. I ultimately wished for more of a conclusive statement of implications in both the introduction and conclusion detailing the novelty of the synthesis and its suggested action steps, as well as the role of this sort of survey in making ecological advances. Including this text might also help highlight broader issues that were not specific sections of the article but that are critical steps for addressing ecological challenges.
It does seem like there is a slightly different authorial voice in some of the sections, as though different sections were written by different people, which makes some of the sections fit together differently than others (for example some sections include a statement of the problem/question in the ‘Background’ subsection, while others do not and include the problem only in the ‘Challenges’ subsection). Some sections are also much longer, and although I don’t think any of the sections are meant to be emphasized more than another, it does have the effect of giving the policy sections a bit more weight. I think it might be helpful to trim the sections a little so that they are more consistent formats and lengths. This might also improve some of the repetitiveness that developed in the later sections of the article. The last 4 sections especially (3.6-3.9) seem to have a lot of overlap and I wonder if there could be different ways to merge some of these ideas that could also reduce the length. Maybe these last sections could be reorganized into a section on biodiversity and conservation, a section on social ecological challenges and inclusivity, and a section on directions for science policy and economics. Alternately, sections 3.7 and 3.8 seem to pose oppositional ideas about including ecosystems in social-economic frameworks and I wonder if merging these sections to highlight the controversy growing in this area might be a way forward. Sections 3.6 and 3.9 also feel quite similar so may be able to be merged. I do think it’s important to highlight that these themes are interconnected as the authors have done, which ultimately means some ideas may be reiterated, but I think there may be ways to trim the text that maintains the spirit of that idea while still making the final sections more distinct.
A final thought for the authors to take or leave--it could be nice to conclude with some sort of conceptual figure that ties all the sections together. Something demonstrating the type of local to global collaboration and action needed across different sectors and disciplines to address specific challenges would be nice. I don’t think this is absolutely necessary but would be great to make the sections feel a bit more cohesive and give the reader a visual overview about how all these parts fit together.
Overall I do think this is a nice summary of many emerging biosphere topics, and the methodology used by the authors, especially if they are able to continue expanding the reach of their solicitation, could be a useful way to identify key areas where research and policy advances are needed.
Section and line specific comments are included below.
Abstract:
Line 3: At the start of the abstract it would be great to add a little detail about the methodology since it seems like that is an important part of what the authors are trying to test as a strategy for generating a report.It would be great if the authors could include an overarching sentence at the end of the abstract stating why the review is important.
Intro:
Line 2: Changes should be changed. First sentence is a little awkward.Line 20: natural processes
Paragraph starting line 45: This seems like information that should have been included in the previous paragraphs when the IPCC reports are introduced. I see how the authors are trying to use it to lead into the idea that these reports are not interdisciplinarily integrative, but if the paragraph stays here, the authors need to make that point more explicit in this paragraph.
Line 53: The authors note here that there is a lack of integrative reporting on the biosphere but I’m not sure the previously stated information convinces me of that entirely, as written. It may be the case for the reports included in the previous paragraph, but could the authors give some explicit examples there?
The final paragraph of the introduction feels a little more like a conclusion. I wonder if this paragraph could be removed or changed to refocus on the idea started in line 75 about climate mitigation and carbon emissions to detail how this overarching concept is woven throughout the 9 key topics.
Methods:
It would be nice to have a little more specific criteria about how these 9 proposal topics were judged and selected aside number of citations of recent literature. Was there a rubric for selection?Insights:
3.1 Coastal habitats
Line 127: Breaking up this sentence would make the ideas presented clearer.Lines 126-137: This paragraph seems more solutions oriented rather than a description of challenges. Possibly move to the next section?
Line 157-159: This short paragraph seems a little out of place. Maybe it could be merged with the previous paragraph?
3.2 Forests and precipitation
The background highlights the important water cycling functions of forests but doesn’t state the question/problem. This might be okay, but other sections do state the problem in the background so it would be nice to make them more consistent.Lines 217-219: The authors note here that evidence is mounting so it seems like it might be important to have multiple references to support the claim, especially since the next sentence notes that, despite this evidence, the effect is not observed in the tropics.
Line 221—I don’t follow this sentence “This suggests that …elsewhere.”
Line 230: “Therefore, also…” is a little odd grammatically. Maybe take out the word “also”?
Line 241: Extra parentheses are included here that aren’t needed.
Line 245: The wording and use of colon here is a little awkward. I think I would switch to “Reforestation has larger effects on several areas of the globe” and leave out the colon (or something along those lines).
Line 235/246: I follow the use of the tipping point term that the authors use in both locations, but the description is somewhat vague. It would help to be explicit what you mean here—maybe “a tipping point at which a forest transitions to a dryland or grassland due to decreased moisture”?
3.3 Fire risks
Line 284: Parenthesis needed before Copernicus rather than after.3.5 20-25% natural habitat in modified landscapes
This section ultimately posits a divide between humans and nature. The following sections discuss the inclusion of humans in nature and recognizing the intrinsic value of the natural world. It might be useful to have some text that discusses these different ways of viewing nature and their relevance to how we make scientific and policy decisions.Line 472: Is there any indication that the spatial arrangement matters? For example, does each individual square kilometer need to be 20-25% natural habitat (so habitat patches) or if you have 2 square kilometers of land but the natural habitat for both is all shifted all to one side in a continuous tract does that achieve the same result? I’m not sure whether there’s an answer but just curious.
Line 490: Missing a parenthesis
3.6 Comprehensive policy packages
The background to this section is much more extensive than the others and states many of the problems upfront while other sections are not organized this way. It would be great to be more consistent between sections.Line 538-543: This part feels like it belongs in the ‘Offering solutions’ section.
This section has a lot more detail than the others and it feels like there is more focus here. It might be helpful to trim or to move to the end and merge with section 3.9, which seems quite similar.
3.7 Convivial conservation
This section also reads as if written by a different author.I wonder if the list of principles outlining convivial conservation could be edited to a summary paragraph that states the main intent, or one sentence per bullet point. This seems a little over-detailed, especially as one of 9 sections.
3.8 Increasing social economic value of ecosystems
Line 725: This section seems to be in direct conflict with the previous section’s suggestions that we do not use capitalist frameworks to analyze ecologic value. Could the authors address this conflict more completely? It seems like these differing ideas should be discussed, or that these two sections could be one section that describes the current debate and ways forward with it.3.9 Biodiversity governance
774: Earth dominating is kind of a strange term. Maybe something else? Could also be removed and the sentence would still work.The background text for this section is a little vague. It relies heavily on knowing the details of the Montreal Global Biodiversity Framework. It would be great if the authors could add a bit more detail about what specific steps might prioritize the GBF.
788: Here the authors state “as for example in Switzerland…” but do not go on to describe the example and detail how it demonstrates the concept described here. This example should be outlined in more detail as should the “larger scale mechanisms” at the end of the sentence.
Conclusions
Line 843: cycle needs an s at the end.Is there a reason why some words from lines 850-878 are in bold text? If so, could that be made clearer?
Line 850: If the idea here is synthesizing the latest science that has been missed by groups like the IPCC and generating new ideas/solutions, it seems a little odd to me that the primary conclusion is so similar to that which is currently the emphasis of these major organizations. This can be an important point—maybe the authors should emphasize, as proposed by the latest IPCC reports, this 1.5 degrees needs to be our major focus—but presenting it as something new or different seems a bit misleading. It would be great to have a statement of what’s new from this synthesis or, alternatively, if this backs up findings from other reports, that should be emphasized.
Line 868: This seems like something that maybe could be a focus—the need to improve monitoring and quantification metrics. Based on the presented focus areas, how do the authors propose to do so and what specific metrics would they like to see?
The conclusion paragraphs starting on like 878 are less repetitive/summary type paragraphs and I wonder if the conclusion could be paired down to focus on these rather than spending as much time on summarizing what was written previously.

Thank you for your constructive and supportive review. Your feedback is invaluable in helping us to communicate our key messages more effectively and to achieve a clearer, more balanced synthesis of the content.This is a useful concept and one that I think could more rapidly advance Earth systems research, as well as improve our tools for addressing climate change. I do wonder if the emphasis on including almost exclusively recent works might exclude issues that have accumulated a large body of work over time but that still have advances in recent years, ultimately reducing some continuity in addressing climate challenges.

Either way, I think the authors could make this intent clearer up front.
We aimed to focus with this paper on recent insights related to the biosphere. Hence drastically reducing fossil fuel consumption - essential for fighting climate change - is not topic of this paper, although this of course is key to addressing biodiversity loss. We will rewrite several sentences in the introduction to make this clearer.
However we will mention in the revised manuscript the long standing insights documented in IPCC and IPBES assessments and other reports in the background sections where it is appropriateI ultimately wished for more of a conclusive statement of implications in both the introduction and conclusion detailing the novelty of the synthesis and its suggested action steps, as well as the role of this sort of survey in making ecological advances. Including this text might also help highlight broader issues that were not specific sections of the article but that are critical steps for addressing ecological challenges.
We will revise the text to better reflect the purpose of this manuscript in the introduction: With this study, we aim to raise awareness of the various challenges within the biosphere and their interconnectedness with other crises within the Earth system, provide synergistic strategies to address complex challenges, and stimulate future research questions.
We will revise the discussion to include findings on integrated decision making, land management strategies, measurement and knowledge generation, and link them to species and climate change objectives.It does seem like there is a slightly different authorial voice in some of the sections, as though different sections were written by different people, which makes some of the sections fit together differently than others (for example some sections include a statement of the problem/question in the ‘Background’ subsection, while others do not and include the problem only in the ‘Challenges’ subsection).
Some sections are also much longer, and although I don’t think any of the sections are meant to be emphasized more than another, it does have the effect of giving the policy sections a bit more weight. I think it might be helpful to trim the sections a little so that they are more consistent formats and lengths. This might also improve some of the repetitiveness that developed in the later sections of the article.
Thank you very much for your suggestions to streamline the manuscript. We will make the following revisions to harmonise the topic sections:
- Each section will be limited or expanded to about 1500 words.
- The background sections will be revised to create a seamless transition from the introduction without redundancy.
- We will improve the challenge sections with clear problem descriptions and ensure coherence with the solutions presented later.
- General recommendations will be avoided in the solution sections.
- For certain topics, we will increase the number of citations to provide a more comprehensive overview of each topic.
- Finally, a core team will review and polish the text to ensure consistency and cohesion.

Thank you very much for your suggestions to re-organise this section and to reduce overlap. We plan to refine the focus of each section to improve clarity, reduce overlap and highlight the interconnectedness. More specifically, we intend the following changes:
- Section 3.6 will focus on holistic policy packages at national and international levels.
- Section 3.7 will focus on the principles of local solutions and inclusive, convivial nature conservation.
- Section 3.8 will analyse the societal value of ecosystems.
- Section 3.9 will be integrated with the previous sections and the revised discussion.
The aim of this reorganisation is to improve the coherence and thematic focus of the topics while maintaining the links between them.
A final thought for the authors to take or leave--it could be nice to conclude with some sort of conceptual figure that ties all the sections together. Something demonstrating the type of local to global collaboration and action needed across different sectors and disciplines to address specific challenges would be nice. I don’t think this is absolutely necessary but would be great to make the sections feel a bit more cohesive and give the reader a visual overview about how all these parts fit together.
Thank you very much for this suggestion. We already have some ideas on how to realise a guiding graphic.
Overall I do think this is a nice summary of many emerging biosphere topics, and the methodology used by the authors, especially if they are able to continue expanding the reach of their solicitation, could be a useful way to identify key areas where research and policy advances are needed.
Thank you very much for these motivating final words and for your valuable suggestions to improve the manuscript.

RC2: 'Comment on egusphere-2024-2551', Anonymous Referee #2, 19 Oct 2024
This manuscript reviews the literature and provides current perspectives on biosphere research from 2021-2024, using an interdisciplinary perspective. They point to similar reviews of other topics (e.g., top 10 topics in climate change) to justify their approach. They also argue that the slow pace of large-scale international reports (e.g., IPCC’s assessment reports) necessitates periodic reviews such as theirs to provide policy relevant information. The goals and objectives of the manuscript are ambitious and laudable, and there are interesting aspects of the synthesis. I feel there is value in the study.
Now, if I put on my critical reviewer hat and really embody the dreaded “reviewer 2” … I felt this was very underbaked. I think this manuscript suffers from the “Frankenstein” effect, in that the sections that comprise the synthesis have just been copied and pasted together by the various section leads, without any polishing or alignment between them. Some sections are roughly double the length of others. There is extensive repetition of information in the latter half of the article. There are also many instances in which boilerplate sentences occur in the latter half of the article, which really do not need to be there. Some of the sections have thoughtful solutions and recommendations that cover a wide base of the challenges, whereas others have extremely cursory recommendations that largely recommend some of the authors’ own views. For example, the NCS implementation risk only provides one suggestion – use tonne-year accounting – which one of the authors has published extensively on, without noting the many studies that have pointed out potential issues with this method. There is also no discussion of the many other challenges associated with NCS implementation (additionality, leakage, environmental justice concerns, financing, non-carbon climatic effects, etc.). Many of the sections also present solutions and recommendations that do not relate to the challenges presented. The result is that for many of the sections, the “emerging topics” that are presented feel surface-level and underdeveloped.
I have five major suggestions to improve this manuscript:
- Identify a subset of the authors (perhaps 1-3) to read through all sections and edit heavily.

I would suggest establishing a word limit or some sort of agreement in terms of the maximum length of sections. This subset of coauthors could read for several things: 1.

Decide what the purpose of the recommendations section is. Some sections just have cursory bullets, others have thoughtful paragraphs with specific examples. Perhaps these recommendations sections are not needed (see point 3).
- Alternatively, consider rewriting each section to identify one key insight from each topic area.

This would also allow you to greatly condense the article and be much more focused. Indeed, the section titles already somewhat suggest this insight – the supporting text just needs to be further developed to more succinctly justify the insight.
- Provide some sort of synthetic thinking across the 9 subject areas. The discussion currently just provides one or two key points from each section, but no synthetic thinking is provided in terms of cross-cutting themes or key areas of research that could address multiple challenges. One suggestion is that rather than providing recommendations (which are typically just bullet points that repeat the information in the solutions section), remove the recommendations and provide a synthetic analysis in or before the discussion… or perhaps compile the recommendations for each topic in some sort of table. For example, support for increased autonomy of Indigenous and local communities was a common solution – and thus drawing out this theme across the topics could be valuable for your intended audience to see.

This would likely provide a much more impactful and meaningful article. You might also consider adding conceptual figures or tables to better convey the information in a much more concise and digestible fashion.
There are also some instances of oversimplification of topics that have the potential to be misused in the recommendations (e.g., “NCS should prioritize reforestation of mangroves”). I work extensively in mangroves and am very partial to these ecosystems – but the field generally believes that conservation of existing natural forests should be prioritized before reforestation; and who is to say that mangroves should be prioritized over other ecosystem types?
It's also worth noting that there are extensive typos and many instances of awkward grammar. Given the accomplishments of the author team, I expected more professionalism in the preparation of the manuscript.
Minor suggestions:
Line 28 – some awkward language; reads as though IPCC & IPBES are “international negotiations,” which they aren’t.
Line 40 – There is a working assumption that IPCC and IPBES are what those implementing biosphere stewardship primarily respond to. Do you have any evidence for that? There are also many other scientific publications that are released (e.g., the annual Global Carbon Budgets) and many land management agencies I think are less tied to these high level reports (thinking of the US Forest Service, which uses national level data and policies).
Line 47 – There is also the “scientists’ warnings” series / community.
Line 53 – How are you defining “biosphere”? IPCC and IPBES include many scenarios that incorporate social and economic trajectories. The planetary thresholds group out of PIK also does lots of similarly themed research, so I’m not sure I buy the idea that this is unaddressed.
Line 68 – Doing my duty as a critical reviewer … I am not sure any of this is novel or an emerging theme. I think it’s clear that biodiversity loss, land degradation, chemical pollution, etc., are all interlinked and driven by social and economic systems.
Line 81 – missing a space before “In the future”
Line 150 – awkward phrasing - “and result in improved”
Section 3.1
Section 3.1.3 – I find this section to be rather abstract, with the solutions space disconnected from the challenges. I agree with the statement that inclusive approaches are a must, but think there is a logical disconnect between how community engagement in restoration is likely to alleviate issues such as coastal squeeze.
Line 175 –unclear/imprecise. Do you mean physical space? Or metaphorical? Stewardship is governance, so I don’t really know what providing hectares for governance means?
Line 177 – Indigenous is typically capitalized as a sign of respect; would recommend this throughout your manuscript.
Line 181 – This statement is very problematic and has great potential to be misused. When designing NBS for CC, there are many other solutions that should be prioritized over mangrove reforestation (e.g., conservation of existing biodiverse mangroves, or providing them accommodation space). I agree with the article’s main argument (that mangrove reforestation is more effective than afforestation), but this bullet point does not capture that at all. Suggest deleting or clarifying.
Section 3.2
Line 222 – Awkward grammar in this paragraph.
Line 241 – empty parentheses
Section 3.2.3 – Is restoring forests, which takes many decades and is extremely limited in terms of spatial footprint, really the solution to the issue of a positive feedback loop between deforestation & increased drought-driven forest loss / degradation? To me, the solution is to halt deforestation before you think about reforestation. The best way to do this is likely through strengthened environmental governance, whether through policies, monitoring, enforcement, more resources, or voting folks into power that care about the issue. You might consider whether reforestation and afforestation should be the focus of this section – or whether it should be more focused on strengthening efforts to halt deforestation (is there any evidence to show restored forests help with water cycling in expansive tropical forests)?
Line 243 – citation? Is this based on modeling in which you have fully restored forests, or empirical data in which forests take many decades to recover structure and canopy cover?
Line 265 – So protecting Amazonian forests from deforestation is not a priority? We have seen massive droughts across the Amazon this year, might consider rephrasing this.
Line 275 – Critical in what sense?
Section 3.3
Line 285 – pulling in opposite directions but regionally distinct, correct? Or are these patterns generally occurring in the same locations?
Line 291 – Interesting – this is a surprising result to me, particularly given the massively extensive fires in the boreal region last year. Also occurrence is rather imprecise. Do you mean extent of fire? Or frequency? Is the general pattern that we are getting fewer but more intense fires across the globe? And this is specific to forests? Or grasslands as well?
Line 318 – This pattern of reduced area of burns with increasing fire conditions sounds like what the US implemented for 100 years and is part of what is now driving catastrophic high-severity fires. I.e., you don’t burn areas that normally burn, fuels build up over decades, and then the climate gets to a point such that all of your accumulated fuels go up in flames at once. There are many fire studies that argue we should rethink our relationship with fire, and start with the fire ecology of the system. (i.e., suppression might not be a great solution).
Line 322 – The U.S. is being MASSIVELY impacted by severe fires – surprised that you find economically developed societies are less affected.
Line 325 – Why not start this solution paragraph with recommending developing an understanding of the fire ecology of the system, and locally adapting strategies and tools for fire management to that system (whether they be suppression, Rx fire, forest types, etc.).
Section 3.3.4 – These are good recommendations.
Section 3.4.
Line 359 – This might be misleading. Terrestrial ecosystems have absorbed a roughly consistent proportion of our annual emissions for several decades but it is due to a mixture of effects – CO2 fertilization is a big one, but also lengthened growing seasons in northern latitudes, and regrowth of forests in northern / developed countries have contributed. I wouldn’t note the Co2 fertilization effect unless you are talking about the fact that terrestrial ecosystems have uptaken roughly the same percentage of our annual emissions over many decades. I also wouldn’t use “additional” removal as additionality has a very specific meaning within Nature-based CDR.
Line 3.4.3. – There are many critiques of tonne-year accounting, and also many other potential solutions to NCS implementation (citing projects in areas where disturbance is less likely, designing solutions to confer resilience to ecosystems, focusing on strategies that might be less prone to disturbance such as agroforestry, etc.). This section feels cursory and under-developed relative to the others. I am also not sure that treating NCS as temporary resolves all implementation risks (thinking about issues related to additionality, leakage, environmental justice, etc. – it only addresses the permanence criteria).
Section 3.5.
This section is well-developed and the logic is consistently threaded through the various sub-sections nicely (background – challenges – solutions – recommendations). In the interest of pushing the authors further, wouldn’t there be unique challenges to restoring 25-30% of every developed square kilometer (this seems massively expensive). What are those social and economic barriers, and do you have concrete ideas for how to work past them?
Section 3.6
This feels like a large enough topic to encompass all other topics covered in this manuscript – is there a way to make this section more focused?
Lines 495-510 – I suggest deleting or condensing this. This section feels longer than the others, and I don’t think this broad framing is needed given the article’s intended audience.
Line 540 – Would this paragraph be better placed in solutions? E.g., reframe policies section to “design policies to transition to a circular economy”
Line 565 – I really like these examples as they provide concrete guidance on policy recommendations, which is lacking in many other sections. However, some of this can be condensed (e.g., you already describe the CBD and other agreements in the intro). Consider focusing the sentence more towards solutions (e.g., keep the sentences on how international agreements can be improved).
Line 605 – I like these recommendations. However, the author team should align the recommendations. Most are just a line or two, whereas these are fleshed out with examples. You might consider condensing these down to pithy recommendations.
Section 3.7
Line 630 – Could delete or rewrite the boilerplate first sentence.
Line 635 – Love that you are bringing political ecology into this. So critical for many of the issues that are highlighted in this article. I think it also adds credence to the interdisciplinarity claims of the article.
Discussion
I am not sure how useful the 2-3 sentence highlights of the 9 topics actually is. Surely, given that you are focused on interconnections across biosphere stewardship, there are synergies across the nine sections. What are those? Can you provide us with some sort of synthetic view or key themes that emerge across all of the areas? This would be most helpful for the policy-makers, environmental stewards, and researchers that you suggest are the audience of this article.

AC2: 'Reply on RC2', Friedrich Bohn, 04 Nov 2024
This manuscript reviews the literature and provides current perspectives on biosphere research from 2021-2024, using an interdisciplinary perspective. They point to similar reviews of other topics (e.g., top 10 topics in climate change) to justify their approach. They also argue that the slow pace of large-scale international reports (e.g., IPCC’s assessment reports) necessitates periodic reviews such as theirs to provide policy relevant information. The goals and objectives of the manuscript are ambitious and laudable, and there are interesting aspects of the synthesis. I feel there is value in the study.
Thank you for your supportive and critical feedback, which is very helpful in improving the manuscript. We appreciate the time you have taken to critically review our manuscript, your insights and the detailed feedback you have provided. We will implement your suggestions, as well as those of reviewer 1, throughout the manuscript.
Now, if I put on my critical reviewer hat and really embody the dreaded “reviewer 2” … I felt this was very underbaked. I think this manuscript suffers from the “Frankenstein” effect, in that the sections that comprise the synthesis have just been copied and pasted together by the various section leads, without any polishing or alignment between them. Some sections are roughly double the length of others. There is extensive repetition of information in the latter half of the article. There are also many instances in which boilerplate sentences occur in the latter half of the article, which really do not need to be there. Some of the sections have thoughtful solutions and recommendations that cover a wide base of the challenges, whereas others have extremely cursory recommendations that largely recommend some of the authors’ own views. For example, the NCS implementation risk only provides one suggestion – use tonne-year accounting – which one of the authors has published extensively on, without noting the many studies that have pointed out potential issues with this method. There is also no discussion of the many other challenges associated with NCS implementation (additionality, leakage, environmental justice concerns, financing, non-carbon climatic effects, etc.). Many of the sections also present solutions and recommendations that do not relate to the challenges presented. The result is that for many of the sections, the “emerging topics” that are presented feel surface-level and underdeveloped.
Thank you very much for your suggestions to streamline the manuscript, and the recommendations for improving the structure to hone in on the most pertinent messages.
I have five major suggestions to improve this manuscript:
- Identify a subset of the authors (perhaps 1-3) to read through all sections and edit heavily. The paper is very lengthy, and unfortunately today, folks tend to have limited time/energy to read lengthy papers. I would suggest establishing a word limit or some sort of agreement in terms of the maximum length of sections. This subset of coauthors could read for several things: 1. Is the background of each topic area relevant and necessary, or is it simply repeating elements of the introduction? 2. Do the proposed solutions and recommendations directly address the challenges identified? Similarly, are they specific enough to actually provide novel insight on the topic, or are they overly general (e.g., “develop policy to solve this”). 3. Decide what the purpose of the recommendations section is. Some sections just have cursory bullets, others have thoughtful paragraphs with specific examples. Perhaps these recommendations sections are not needed (see point 3).
Thank you very much for these suggestions that are very helpful in highlighting the key messages we want to convey. We will revise the manuscript by undertaking the following steps
- Each section will be limited or expanded to about 1500 words.
- The background sections will be revised to create a seamless transition from the introduction without redundancy.
- We will improve the challenge sections with clear problem descriptions and ensure coherence with the solutions presented later.
- General recommendations will be avoided in the solution sections.
- Finally, a core team will review and polish the text to ensure consistency and cohesion
- Alternatively, consider rewriting each section to identify one key insight from each topic area. Rather than providing a mini-review of all challenges and trying to highlight multiple solutions and recommendations, pick one insight (ala the Martin et al. 10 insights for climate science piece you reference). I think this would help prevent the reader from feeling like the authors have left out many important areas – as they will expect that you will not address all areas from the beginning. This would also allow you to greatly condense the article and be much more focused. Indeed, the section titles already somewhat suggest this insight – the supporting text just needs to be further developed to more succinctly justify the insight.
We prefer to follow your first suggestion and still take some elements from this second point to improve focus and clarity:
- We will clearly state that this list is not exhaustive and that future publications will cover additional topics, as we plan to publish this type of paper on a regular basis (probably annually).
- We will also streamline and refine the longer sections, removing repetition to eliminate excessively long passages, so that each topic remains concise and focused.
- Provide some sort of synthetic thinking across the 9 subject areas. The discussion currently just provides one or two key points from each section, but no synthetic thinking is provided in terms of cross-cutting themes or key areas of research that could address multiple challenges. One suggestion is that rather than providing recommendations (which are typically just bullet points that repeat the information in the solutions section), remove the recommendations and provide a synthetic analysis in or before the discussion… or perhaps compile the recommendations for each topic in some sort of table. For example, support for increased autonomy of Indigenous and local communities was a common solution – and thus drawing out this theme across the topics could be valuable for your intended audience to see.
Thank you for this valuable suggestion for a more synthetic discussion. We will revise the discussion section, restructure the synthesis section, and organise our recommendations around the following key themes: improving inclusive decision-making, advancing land management strategies, improving measurement and knowledge generation, and linking these findings to the goals of species conservation and climate change mitigation.
- Provide more details and information on the actual data collection / whittling of ideas down in supplementary information. As I mention above, I am not convinced that all sections sufficiently address emerging trends across each topic. I know it is impossible to cover everything, but there appears to be a bias towards the work of the coauthors for several of the topics. There should be more transparency in how these topics were arrived at, given that they might influence future policy, research, action, etc.
Thank you for sharing your considerations. To better address how the topics covered were selected, we will work on the following points:
- We will include an appendix with the questionnaire used in our study and revise the methods section.
- For some topics we will increase the number of citations to provide a more comprehensive representation of different perspectives in each area.
- As mentioned earlier, we will emphasise that this collection does not claim to be comprehensive and absolute. Rather, it is our intention to publish this type of work on a regular basis, ideally annually.
- Alternative to all the above – and this would involve a massive overhaul of the manuscript – I feel the 9 sections could actually be supplementary information themselves, and some sort of synthetic distillation of everything in a much shorter manuscript could be written. This would likely provide a much more impactful and meaningful article. You might also consider adding conceptual figures or tables to better convey the information in a much more concise and digestible fashion.
Thank you very much for sharing your conceptual ideas on how to approach a manuscript such as ours that provides an overview over the current issues in biosphere science. As this project is planned to be repeated annually, we will seriously consider these suggestions for the next paper in this series. We will develop a conceptual figure. However, for the current manuscript, we will skip this alternative route in order to publish the paper as soon as possible.
There are also some instances of oversimplification of topics that have the potential to be misused in the recommendations (e.g., “NCS should prioritize reforestation of mangroves”). I work extensively in mangroves and am very partial to these ecosystems – but the field generally believes that conservation of existing natural forests should be prioritized before reforestation; and who is to say that mangroves should be prioritized over other ecosystem types?
We will adapt this statement and carefully review others.
It's also worth noting that there are extensive typos and many instances of awkward grammar. Given the accomplishments of the author team, I expected more professionalism in the preparation of the manuscript.
We will carefully edit the manuscript to remove any awkward grammar and typos.We will also revise the text based on your helpful and constructive minor suggestions.
Thank you very much for your assistance in improving this manuscript. Although you consider yourself as being the “dreaded reviewer2”, we found your comments very constructive and helpful in improving the manuscript.
Friedrich Bohn on behalf of all Co-Authors.
