Evaluation of policies and actions for nature-based solutions in nationally determined contributions
Land Use Policy Volume 131, August 2023, 106710 (2023). Systematic Review.
https://doi.org/10.1016/j.landusepol.2023.106710Abstract
Nature-based solutions (NbS) have been gradually valued by various countries because they have great potential for contributing to the Paris Agreement goals and carbon neutrality and meanwhile render synergies in various dimensions. Currently, the evaluation of NbS policies in the Nationally Determined Contributions (NDCs) is still quite lacking. Based on the NDCs documents of 190 countries and the initial subcategories of related researches, this paper proposes a NbS analysis framework covering targets, pathways, policies, and synergies. Then examining the characteristics of NbS policies and actions of 190 Parties by ecosystems, including forests, farmlands, grasslands, coastal zones & wetlands, urban ecosystems, and other ecosystems with the framework. The results show that: 1) NbS has not yet become the mainstream measure worldwide to combat climate change while developing countries pay more attention to NbS than developed countries; 2) Current NbS targets set by 131 countries(about 69 %) are qualitative and 59 countries(about 31 %) for quantitative. There is no robust and accurate quantitative indicator system for NbS; 3) NbS pathways mentioned by 156 countries (about 82 %) are unevenly distributed in ecosystems and concentrated in forest and farmland ecosystems; 4) Just over a third of the 190 countries (about 35 %) don’t apply any NbS pathways with scientific foundations and only 27 parties (about 14 %) announce strengthening the related research of NbS pathways in supporting policies in the future. The scientific foundations of NbS are undervalued and more NbS pathways with reliable scientific foundations should be implemented; 5) A variety of policies, predominantly planning and law, have been adopted by 130 countries (about 68 %) to ensure NbS actions. Other types of policies still need to be further improved, covering financing, information system &research, and capacity building; 6) Funding needs are unclear and financing mechanisms are imperfect for NbS actions. Only about 1/6 of the countries have suggested estimated funding needs of NbS actions; 7) Only 18 countries (about 9.5 %) have recognized the synergistic benefits of NbS in economic, social, and environmental dimensions, and there are relatively limited methodologies for the assessment of NbS synergies. At last, suggestions are put forward to further promote NbS contributions to tackling climate change.
Nature-based solutions in generalClimate change adaptationClimate change mitigationEcosystem healthAbandoning land transforms biodiversity: Land abandonment is critical when assessing global biodiversity and conservation
SCIENCE 11 May 2023 Vol 380, Issue 6645 (2023). Perspective.
https://doi.org/10.1126/science.adf1099Abstract
Land abandonment and rural depopulation are accelerating globally. In less than 50 years, the proportion of the human population living in rural areas has decreased by ∼25% (1). Abandonment takes many shapes, and no single definition has been accepted. Most often, land abandonment refers to a termination of agricultural activities for at least 5 years (to differentiate it from fallow land) and is quantified at the crop-field scale (2, 3). Other types of abandonment have received less attention, such as abandoned pastures, forestry areas, mines, factories, and entire human settlements. Here, “land abandonment” broadly captures the end of human activities. Since the 1950s, abandoned land has accumulated to up to 400 million ha globally (3), an area roughly half the size of Australia. Given this scale, there is an urgent need to develop a vision of how to achieve balanced benefits for biodiversity conservation, ecosystem services, and people’s livelihoods on abandoned land.
Ecological restorationEcosystem healthAssisted tree migration can reduce but not avert the decline of forest ecosystem services in Europe
Global Environmental Change Volume 80, May 2023, 102676 (2023). Review.
https://doi.org/10.1016/j.gloenvcha.2023.102676Abstract
European forests are facing multiple natural and anthropogenic pressures that are expected to become more severe in the next decades. Tree diversity is projected to decline in many areas across the continent. How this will affect the provision of forest services remains an open question, whose answer depends, among others, on the practical and theoretical challenges of incorporating assisted migration into climate adaptation strategies. Here, we tackle the issue by combining a large dataset of tree species occurrences, future climatic projections, and data on tree functional traits and tree-specific forest services into a novel modelling framework.
Ecosystem-based managementForest landscape restorationEcosystem healthForestMore than one quarter of Africa’s tree cover is found outside areas previously classified as forest
Nature Communications volume 14, Article number: 2258 (2023). Systematic Review.
https://doi.org/10.1038/s41467-023-37880-4Abstract
The consistent monitoring of trees both inside and outside of forests is key to sustainable land management. Current monitoring systems either ignore trees outside forests or are too expensive to be applied consistently across countries on a repeated basis. Here we use the PlanetScope nanosatellite constellation, which delivers global very high-resolution daily imagery, to map both forest and non-forest tree cover for continental Africa using images from a single year. Our prototype map of 2019 (RMSE = 9.57%, bias = −6.9%). demonstrates that a precise assessment of all tree-based ecosystems is possible at continental scale, and reveals that 29% of tree cover is found outside areas previously classified as tree cover in state-of-the-art maps, such as in croplands and grassland. Such accurate mapping of tree cover down to the level of individual trees and consistent among countries has the potential to redefine land use impacts in non-forest landscapes, move beyond the need for forest definitions, and build the basis for natural climate solutions and tree-related studies.
Forest landscape restorationEcosystem healthForestA Balancing Act for Brazil’s Amazonian States: An Economic Memorandum
Open Knowledge: International Development in Focus (2023). Perspective.
https://openknowledge.worldbank.org/handle/10986/39778Abstract
Brazil’s nine Amazonian states, here collectively referred to as Amazônia, include some of the world’s richest ecosystems, including the Amazon rainforest and parts of the Cerrado savanna and Pantanal wetlands. The region is also among Brazil’s poorest socioeconomically. As a result, sustainable, inclusive development of Amazônia calls for raising living standards while protecting natural forests. A Balancing Act for Brazil’s Amazonian States: An Economic Memorandum explores how a recalibrated development approach can achieve these goals. In the shorter term, there is an urgent need to halt deforestation–a massive destruction of natural wealth that poses risks to the climate and economy. Amazônia is Brazil’s deforestation hot spot, and the Amazon rainforest is approaching tipping points into broad and permanent forest loss. Reversing the recent increase in deforestation requires stronger land and forest governance, including land regularization and more effective law enforcement. In the longer term, both Brazil and Amazônia need a new growth model. This model would be anchored in productivity rather than resource extraction and it would diversify the export basket beyond commodities. A more balanced structural transformation requires the lagging urban sectors, such as manufacturing and services, to step up to promote economic growth, reduce pressure on the agricultural frontier, and generate jobs for Brazil and Amazônia’s largely urban populations. The public-good value of Amazônia’s forests could generate conservation finance linked to verifiable reductions in deforestation. Such financing would support a new development approach, combining forest protection, productivity, balanced structural transformation, sustainable production techniques (including the bioeconomy), and other measures to address the needs of Amazônia’s urban and rural populations. This approach must also heed the needs and interests of Amazônia’s traditional communities. Given both the value and the fragility of Amazônia’s ecosystems, coupled with considerable socioeconomic local needs, the stakes are high—for Amazônia, Brazil, and the world.

https://www.science.org/doi/full/10.1126/science.adf4155Abstract
Laws that establish legal rights for nature are being pursued in a growing number of countries to protect the environment. The success or failure of these rights-of-nature laws can depend in large part on how scientific concepts and expertise have been used to develop, interpret, and implement them. Epstein et al. reviewed key scientific aspects of rights-of-nature laws and the use of science in court decisions that have interpreted them. They examined the “right to evolve” to illustrate challenges in applying scientific concepts in rights-of-nature laws and identify some possible solutions.
Not applicableHuman well-being & developmentA global conservation basic income to safeguard biodiversity
Nat Sustain (2023). (2023). Perspective. Review.
https://doi.org/10.1038/s41893-023-01115-7Abstract
Biodiversity conservation supporting a global sustainability transformation must be inclusive, equitable, just and embrace plural values. The conservation basic income (CBI), a proposed unconditional cash transfer to individuals residing in important conservation areas, is a potentially powerful mechanism for facilitating this radical shift in conservation. This analysis provides comprehensive projections for potential gross costs of global CBI using spatial analyses of three plausible future conservation scenarios. Gross costs vary widely, depending on the areas and populations included, from US$351 billion to US$6.73 trillion annually. A US$5.50 per day CBI in existing protected areas in low- and middle-income countries would cost US$478 billion annually. These costs are large compared with current government conservation spending (~US$133 billion in 2020) but represent a potentially sensible investment in safeguarding incalculable social and natural values and the estimated US$44 trillion in global economic production dependent on nature.
Not applicableHuman well-being & developmentThe sound of restored soil: using ecoacoustics to measure soil biodiversity in a temperate forest restoration context
Restoration Ecology (2023). Original Research.
https://onlinelibrary.wiley.com/doi/10.1111/rec.13934Abstract
Forest restoration requires monitoring to assess above- and belowground communities, which is challenging due to practical and resource limitations. Ecological acoustic survey methods––also known as “ecoacoustics”––are increasingly available and provide a rapid, effective, and non-intrusive means of monitoring biodiversity. Aboveground ecoacoustics is widespread, but soil ecoacoustics has yet to be utilized in restoration despite its demonstrable effectiveness at detecting soniferous soil meso- and macrofauna. This study applied ecoacoustic tools and indices (Acoustic Complexity Index, Normalized Difference Soundscape Index, and Bioacoustic Index) to measure belowground (and aboveground as secondary) biodiversity in a forest restoration site spanning two age classes. We collected n = 198 belowground acoustic samples and n = 180 aboveground samples from three recently deforested (felled <3 years ago) and three deciduous forest plots undergoing restoration (for the last 30–51 years) across three monthly visits in South Yorkshire, U.K. We used a belowground sampling device and sound-attenuation chamber to record soil communities and passive acoustic monitoring to record aboveground sounds. We found that restored plot acoustic complexity and diversity were significantly higher than deforested plots in the sound-attenuation chamber, but there were no inter-plot differences in in-situ soil or aboveground samples. We also found that restored plots had a significantly greater high-frequency to low-frequency ratio (suggesting higher biophony to anthrophony ratios) for in-situ and sound chamber soil but no association for aboveground samples. Our results suggest that ecoacoustics has immense potential to monitor belowground biodiversity, adding to the restoration ecologist’s toolkit and supporting global ecosystem recovery.
OtherEcosystem healthForestNature as a solution for shoreline protection against coastal risks associated with ongoing sea-level rise
Ocean & Coastal Management, Volume 235, 2023, 106487 (2023). Review.
https://doi.org/10.1016/j.ocecoaman.2023.106487Abstract
The risks from climate change are ever-growing, especially in more vulnerable and exposed regions such as coastlines. The rise in sea level and increase in the frequency and intensity of climate-induced coastal hazards are threatening the increasing coastal populations. Brazil, with its 8,500 km of coast, is one of the countries most at risk from coastal flooding and erosion. Nature-based solutions have been suggested as climate adaptation strategies with the greatest potential to counteract coastal hazards stemming from sea-level rise and safeguard coastal cities. However, there is still a knowledge gap in the scientific literature on the effectiveness of nature-based solutions, especially at large spatial scales in Central and South America. Here, we assessed the risks from climate-induced hazards of coastal erosion and flooding related to sea-level rise on the Brazilian coast, and the effectiveness of nature-based solutions as climate adaptation strategies. We reveal that nature-based shoreline protection can reduce by 2.5 times the risks to the Brazilian coastline. The loss of existing natural habitats would substantially increase the area and population at risk from these climate-induced hazards. Worrisomely, legal mechanisms to protect these natural habitats are few and being weakened. Only 10% of the coastal natural habitats are within protected areas, and these alone do not ensure coastal protection, as our results indicate that the loss of unprotected natural habitats has about the same risk as the total absence of natural habitats. Our results warn of the severe consequences of the continued loss of natural habitats along the coast. Thus, actions towards the maintenance and protection of coastal habitats are paramount for climate adaptation and to ensure the well-being and livelihoods of coastal populations. Brazil has a central role in demonstrating the benefits of strategies based on nature-based solutions for shoreline protection, favoring their implementation worldwide. We provide both the natural habitat maps and the maps with model results with spatial and numerical information so readers can explore the relations between the natural habitats and coastal risk indexes at a sub-national level and foster their use by local stakeholders.

https://doi.org/10.1038/s43016-023-00751-8Abstract
Côte d’Ivoire and Ghana, the world’s largest producers of cocoa, account for two thirds of the global cocoa production. In both countries, cocoa is the primary perennial crop, providing income to almost two million farmers. Yet precise maps of the area planted with cocoa are missing, hindering accurate quantification of expansion in protected areas, production and yields and limiting information available for improved sustainability governance. Here we combine cocoa plantation data with publicly available satellite imagery in a deep learning framework and create high-resolution maps of cocoa plantations for both countries, validated in situ. Our results suggest that cocoa cultivation is an underlying driver of over 37% of forest loss in protected areas in Côte d’Ivoire and over 13% in Ghana, and that official reports substantially underestimate the planted area (up to 40% in Ghana). These maps serve as a crucial building block to advance our understanding of conservation and economic development in cocoa-producing regions.
Nature-based agricultural systemsClimate change adaptationWildfire and degradation accelerate northern peatland carbon release
Nature Climate Change volume 13, pages456–461 (2023) (2023). Original Research.
https://www.nature.com/articles/s41558-023-01657-wAbstract
The northern peatland carbon sink plays a vital role in climate regulation; however, the future of the carbon sink is uncertain, in part, due to the changing interactions of peatlands and wildfire. Here, we use empirical datasets from natural, degraded and restored peatlands in non-permafrost boreal and temperate regions to model net ecosystem exchange and methane fluxes, integrating peatland degradation status, wildfire combustion and post-fire dynamics. We find that wildfire processes reduced carbon uptake in pristine peatlands by 35% and further enhanced emissions from degraded peatlands by 10%. The current small net sink is vulnerable to the interactions of peatland degraded area, burn rate and peat burn severity. Climate change impacts accelerated carbon losses, where increased burn severity and burn rate reduced the carbon sink by 38% and 65%, respectively, by 2100. However, our study demonstrates the potential for active peatland restoration to buffer these impacts.
Climate change mitigationOtherOpportunities for nature-based solutions to contribute to climate-resilient development pathways
Current Opinion in Environmental Sustainability Volume 62, June 2023, 101297 (2023). Original Research.
https://doi.org/10.1016/j.cosust.2023.101297Abstract
There is potential for nature-based solutions (NbS) to contribute to climate-resilient development (CRD) due to their integrated approach to mitigation, adaptation, and sustainable development. However, despite alignment between NbS and CRD’s objectives, realization of this potential is not guaranteed. A CRD pathways (CRDP) approach helps to analyze the complexities of the relationship between CRD and NbS, and a climate justice lens enables the identification of the multiple ways that NbS can support or undermine CRD by foregrounding the politics inherent in deciding between NbS trade-offs. We use stylized vignettes of potential NbS to examine how the dimensions of climate justice reveal the potential of NbS to contribute to CRDP. We consider tensions in NbS projects between local and global climate objectives, and the potential for NbS framing to reinforce inequalities or unsustainable practices. Ultimately, we present a framework that combines climate justice and CRDP in an analytical tool for understanding the potential for a NbS to support CRD in specific places.

Global biodiversity loss has been disproportionately driven by consumption of people in rich nations. The concept of ‘loss and damage’ — familiar from international agreements on climate change — should be considered for the effects of biodiversity loss in countries of the Global South.

Nature volume 619, pages102–111 (2023) (2023). Original Research.
https://www.nature.com/articles/s41586-023-06083-8Abstract
The stability and resilience of the Earth system and human well-being are inseparably linked yet their interdependencies are generally under-recognized; consequently, they are often treated independently. Here, we use modelling and literature assessment to quantify safe and just Earth system boundaries (ESBs) for climate, the biosphere, water and nutrient cycles, and aerosols at global and subglobal scales. We propose ESBs for maintaining the resilience and stability of the Earth system (safe ESBs) and minimizing exposure to significant harm to humans from Earth system change (a necessary but not sufficient condition for justice). The stricter of the safe or just boundaries sets the integrated safe and just ESB. Our findings show that justice considerations constrain the integrated ESBs more than safety considerations for climate and atmospheric aerosol loading. Seven of eight globally quantified safe and just ESBs and at least two regional safe and just ESBs in over half of global land area are already exceeded. We propose that our assessment provides a quantitative foundation for safeguarding the global commons for all people now and into the future.
Nature-based solutions in generalHuman well-being & developmentResponding to Environmental Issues through Adaptive Collaborative Management
Routledge eBook ISBN9781003325932 (2023). Book (chapter).
https://doi.org/10.4324/9781003325932Abstract
Focused on forest management and governance, this book examines two decades of experience with Adaptive Collaborative Management (ACM), assessing both its uses and improvements needed to address global environmental issues.
The volume argues that the activation and the empowerment of local peoples are critical to addressing current environmental challenges and that this must be enhanced by linking and extending such stewardship to global and national policymakers and actors on a broader scale. This can be achieved by employing ACM’s participatory approach, characterized by conscious efforts among stakeholders to communicate, collaborate, negotiate and seek out opportunities to learn collectively about the impacts of their action. The case studies presented here reflect decades of experience working with forest communities in three Indonesian Islands and four African countries. Researchers and practitioners who participated in CIFOR’s early ACM work had the rare opportunity to return to their research sites decades later to see what has happened. These authors reflect critically on their own experience and local site conditions to glean insights that guide us in more effectively addressing climate change and other forest-related challenges. They showcase how global and regional actors will have to work more closely with smallholders, Indigenous Peoples and local communities, recognizing the key local roles in forest stewardship.
This book will be of great interest to students, scholars and practitioners working in the fields of conservation, forest management, community development, natural resource management and development studies more broadly.

Ecology 120 (23) e2208376120 (2023). Original Research.
https://doi.org/10.1073/pnas.2208376120Abstract
Despite efforts to promote sustainable agriculture, food and agricultural production remain the main driver of global biodiversity loss. However, where food production conflicts with biodiversity conservation and which products and countries contribute the most has not been as comprehensively assessed. Based on spatial models of farming and conservation priority areas, we estimate how production and consumption of 48 agricultural commodities driven by 197 countries may conflict with conservation priorities for 7,143 species. This study provides a quantitative basis to better understand and manage the large-scale transformative changes between humanity and nature through decisions concerning food consumption, production, and trade.
Demand for food products, often from international trade, has brought agricultural land use into direct competition with biodiversity. Where these potential conflicts occur and which consumers are responsible is poorly understood. By combining conservation priority (CP) maps with agricultural trade data, we estimate current potential conservation risk hotspots driven by 197 countries across 48 agricultural products. Globally, a third of agricultural production occurs in sites of high CP (CP > 0.75, max = 1.0). While cattle, maize, rice, and soybean pose the greatest threat to very high-CP sites, other low-conservation risk products (e.g., sugar beet, pearl millet, and sunflower) currently are less likely to be grown in sites of agriculture–conservation conflict. Our analysis suggests that a commodity can cause dissimilar conservation threats in different production regions. Accordingly, some of the conservation risks posed by different countries depend on their demand and sourcing patterns of agricultural commodities. Our spatial analyses identify potential hotspots of competition between agriculture and high-conservation value sites (i.e., 0.5° resolution, or ~367 to 3,077km2, grid cells containing both agriculture and high-biodiversity priority habitat), thereby providing additional information that could help prioritize conservation activities and safeguard biodiversity in individual countries and globally. A web-based GIS tool at https://agriculture.spatialfootprint.com/biodiversity/ systematically visualizes the results of our analyses.
