summary

Biodiversity and the variety of living organisms across crops, pollinators, soils, and aquatic ecosystems underpin the functioning of food systems. By supporting pollination, natural pest control, nutrient cycling, soil health, and resilient landscapes, biological diversity contributes to the reliability, safety, and nutritional quality of the food that people eat. The topic emphasizes agrobiodiversity and landscape-scale diversity as central to sustainable production, livelihoods, and cultural food practices, while highlighting that the benefits vary by context and management. A growing body of evidence links richer biodiversity in farming and coastal ecosystems with more stable yields, better nutrient profiles, and increased resilience to climate shocks. Practices such as agroecology, intercropping, habitat restoration, and landscape heterogeneity are repeatedly shown to enhance ecosystem services, from wild pollinator networks to soil microbial communities, and to support both rural incomes and consumer access to diverse foods. Policy approaches increasingly frame biodiversity and ecosystem services as integrated pathways to food security, while recognizing the need for context-specific design and farmer participation. Despite the clear potential, there are notable uncertainties and debates surrounding how large and how durable biodiversity benefits are across different systems. Evidence quality, study design, and local conditions influence observed effects, raising questions about the magnitude of trade-offs between short-term yields and long-term conservation goals. Critics call for stronger cross-sector governance, standardized monitoring, and open data to translate ecological findings into robust policy and scalable practice, while acknowledging that some approaches may require time, investment, and adaptation before benefits materialize at scale. Policy, economics, and implementation are central to turning biodiversity protections into tangible food-security gains. The lead questions concern how to finance and incentivize biodiversity-friendly farming, align fisheries and coastal management with restoration goals, and ensure equitable access to the resulting foods. Proposals include blended finance, price signals for ecological production, and community-driven restoration with durable governance, all framed within broader goals of climate resilience, sustainable development, and inclusive food systems. Ongoing research emphasizes monitoring, decision-support tools, and international cooperation to sustain biodiversity while delivering abundant, high-quality food for present and future generations.

Overview

Biodiversity underpins many ecosystem services that are essential for sustainable food production, including pollination, pest regulation, nutrient cycling, and soil health, all of which contribute to food security and nutrition. Agrobiodiversity, in particular, enhances resilience and sustainability in farming systems, supporting rural livelihoods while preserving cultural food practices and diets. Conceptual and empirical work across disciplines emphasizes that maintaining diverse biological communities is fundamental to the stability and productivity of agricultural systems over the long term. Policy and knowledge frameworks increasingly model biodiversity and ecosystem services as integrated pathways to improve food availability, safety, and utilization, with a focus on farmer knowledge and participatory approaches to manage diversification and soil-health interventions effectively. The Environmental Systems Framework (ESF) and similar analytic lenses have been used to articulate mechanisms by which diversification translates into pest and disease suppression and other outcomes, highlighting how farmer engagement shapes the success of ecosystem-service interventions. In pursuing food security, four interrelated dimensions are commonly recognized: production and availability, stability of supply, access (economic and physical), and safety and utilization, all of which can be strengthened by biodiversity-friendly practices in soils and landscapes. Nevertheless, limitations remain in the evidence base. While many studies indicate that biodiversity supports key agricultural services, the magnitude and significance of these effects can vary depending on data quality, study design, and contextual factors, underscoring the uncertainty inherent in translating ecological findings into robust policy prescriptions. Systematic reviews often reflect this uncertainty by scoring data quality for interactions and acknowledging that effects may not be consistently significant across studied variables. Consequently, ongoing research and adaptive management are needed to refine our understanding of how best to protect biodiversity while delivering high-quality, abundant food for all.

Biodiversity in Food Systems

Biodiversity underpins the reliability and productivity of food systems by delivering essential ecosystem services such as pollination, pest control, and soil fertility. A diverse array of crops, wild crop relatives, pollinators, soil organisms, and other beneficial species collectively sustain crop yields and nutritional quality, while helping farms withstand pests, diseases, and climate-related stresses. In particular, pollinators and pollination services are closely linked to higher crop yields and better quality produce, with multiple meta-analyses showing positive effects of pollinator diversity and abundance on agricultural outcomes. Additionally, functional diversity (the variety of species roles such as predation, pollination, and nutrient cycling) supports regulatory services that are critical for safe, nutritious food production. Soil biodiversity plays a central role in long-term soil health and crop productivity. A rich soil biota promotes nutrient cycling, organic matter turnover, and soil structure, while degraded soils with simplified biological communities often exhibit reduced water infiltration and greater vulnerability to erosion and drought. The maintenance of diverse soil life, including bacteria, fungi, and other microorganisms, is therefore foundational to sustainable crop production and nutrient availability. Agricultural practices that foster biodiversity (such as agroecology, intercropping, and landscape heterogeneity) tend to increase system resilience and long-term profitability. Agroecological approaches are associated with higher biodiversity and improved ecosystem services, contributing to stable yields and potential for price premiums through differentiated markets that reward agroecologically produced crops. In addition, diversified cropping systems and intercropping designs tend to be more resilient to pests, external shocks, and climate variability, supporting consistent food supply and quality over time. Landscape-scale management that enhances habitat diversity (such as maintaining semi-natural habitats, flower strips, hedgerows, and meadow networks) supports beneficial species, including wild pollinators and natural pest controllers. Meta-analytic and synthesis evidence indicates that increased landscape complexity yields positive biodiversity outcomes and strengthens pollination and pest-control services, which can translate into higher agricultural productivity and more stable yields. The protection and restoration of semi-natural habitats are frequently recommended as policy instruments within agricultural frameworks to sustain ecosystem services essential for food security. A comprehensive approach to protecting biodiversity in food systems also involves supporting soil microbial diversity and root-associated mutualists (e.g., rhizobia and mycorrhizal fungi), which contribute to nutrient acquisition and plant health. Changes in soil moisture and other environmental conditions can modulate microbial communities, but targeted management (such as moisture-aware practices and reduced soil disturbance) can help sustain beneficial microbial diversity critical for sustainable crop production. The integration of diverse microbial and plant diversity is increasingly recognized as a driver of ecological intensification and improved nutrient cycling in agricultural lands. Finally, to translate biodiversity gains into tangible food security, it is important to align incentives and policies with biodiversity-friendly farming. Evidence suggests that the resilience and profitability of agroecological methods, including multi- and intercropping and enhanced landscape connectivity, can deliver both ecological and economic benefits, challenging the notion that biodiversity-friendly farming is only suitable for smallholders. Policy instruments that reward biodiversity, such as price-differentiated markets and eco-schemes within agricultural policy, can help scale sustainable practices and ensure ongoing access to diverse, high-quality foods.

Biodiversity Threats Relevant to Food Security

Biodiversity loss and degradation pose direct and indirect threats to food security by undermining the ecosystem services that underpin sustainable agricultural production, including pollination, pest control, nutrient cycling, and soil health. Agricultural intensification and landscape simplification are repeatedly highlighted as major drivers of declines in pollinator diversity, natural enemies of pests, and overall ecosystem resilience, thereby jeopardizing crop yields and nutritional quality. Habitat loss and fragmentation reduce the availability of critical habitats for pollinators, predators, and soil microbes that contribute to disease suppression, pest control, and nutrient cycling. Coastal and agricultural mosaics that lose habitat complexity can diminish nursery areas for beneficial species and disrupt predator-prey and pollinator networks, leading to cascading effects on crop production. Monocultures and crop diversification patterns influence microbial and insect communities in soils and on farms. Monoculture systems are associated with altered soil microbial diversity and lower resilience, while diversification can support beneficial microbes and biological control agents, improving yield stability and reducing vulnerability to pests and diseases. The shift toward simplified cropping systems is linked with decreased pollination services and diminished biological control, contributing to lower crop yields and quality over time. Pesticide use and chemical inputs interact with biodiversity by directly affecting non-target organisms and altering soil and ecosystem processes. Certain pesticides suppress soil enzyme activities and microbial biomass at higher doses, while others can stimulate some microbial processes at lower doses, illustrating complex and sometimes counterproductive effects on soil health and crop performance. The disruption of microbial networks can propagate through trophic levels, reducing nutrient availability, disease resistance, and overall productivity. Agricultural expansion, mangrove and coastal habitat clearance, and other land-use changes threaten biodiversity-rich habitats that support nursery grounds for commercially important species and provide resilience against climate shocks. Loss of natural habitats can limit the provisioning of ecosystem services (such as pollination, pest suppression, and soil fertility) that are essential for stable, high-quality food production, increasing vulnerability to climate variability and market fluctuations.

Evidence-Supported Conservation and Restoration Pathways

Coastal and marine ecosystems provide essential habitat and provisioning services that underpin food security and livelihoods, yet face persistent declines due to stressors such as warming, habitat loss, and exploitation. Restoration and protection efforts can reverse declines and rebuild ecosystem functions when designed and monitored over appropriate time scales. For example, restoration of seagrass habitats in coastal Virginia substantially increased fish abundance and diversity within restored beds compared with adjacent unvegetated areas, with effects persisting and increasing as reefs aged, though outcomes varied with annual conditions and physical drivers such as salinity and tidal regime. These findings underscore that restoration benefits to habitat structure and biodiversity can accrue over multi-year horizons and require long-term monitoring to disentangle drivers of success across sites and years. Experimental and applied restoration work also demonstrates the potential of seed-based and multi-species approaches to accelerate habitat recovery. Trials testing widgeongrass (Ruppia maritima) restoration showed that direct fall seeding can establish viable stands and that seeding multiple seagrass species can maximize restored area, even enabling expansion into high-temperature waters unsuitable for other seagrasses such as eelgrass, thereby enhancing overall bed complexity and potential biodiversity. The integration of seed-based restoration with existing foundation species restoration (e.g., eelgrass) can yield substantial gains in restored extent and subsequent ecosystem services, illustrating how mixed-method restoration can broaden resilience under changing environmental conditions. Beyond local-scale restoration, nature-based coastal protection and habitat restoration are increasingly framed within global policy horizons. The expansion of marine protected areas (MPAs) and shore-zone habitats such as surf zones and sandy beaches has shown regionally variable effects on fish assemblages, but benefits in some regions include higher abundance, richness, and biomass inside MPAs, highlighting the context-dependency of protection outcomes and the value of targeted monitoring across landscapes. At the policy level, ongoing international frameworks (such as the United Nations Decade on Ecosystem Restoration (2021–2030) and the post-2020 biodiversity framework) emphasize restoring wetland ecosystems and setting quantitative restoration targets across freshwater and marine habitats, providing a top-down impetus to scale successful practices and align restoration with biodiversity and food-security goals. To maximize effectiveness, restoration initiatives must be guided by robust, standardized monitoring and cross-site learning. Calls for standardized frameworks to measure restoration outcomes, biodiversity responses, and ecosystem services highlight the need for coordinated metrics and consistent methodologies to compare across studies and regions, enabling more reliable assessments of what works under diverse environmental and socio-economic conditions. In parallel, recognizing the linkages between habitat restoration, pollinator networks, and agricultural productivity suggests integrating biodiversity conservation with agricultural policy and land-use planning to sustain ecosystem services that support high-quality food production. Incorporating climate resilience, multi-species approaches, and adaptive management will further strengthen evidence-supported pathways. Climate change necessitates selecting generalist, resilient species and life-history strategies that can persist under shifting conditions, while monitoring must remain adaptive to track changing species responses and inform iterative restoration design. Collectively, the evidence supports a pathway that combines habitat protection, targeted seagrass-based restoration (including seed methods and multi-species approaches), rigorous long-term monitoring, policy alignment through global restoration agendas, and adaptive management to sustain biodiversity and ensure abundant, high-quality food for humanity.

Conservation Outcomes for Food Security: What Is Commonly Measured

Conservation-related outcomes for food security are frequently assessed through a combination of agronomic, ecological, and socio-economic indicators that capture how biodiversity, ecosystem services, and management practices translate into food availability, quality, and resilience. In practice, researchers and policymakers track measures across soils, crops, pollination, and marine-resource contexts to gauge potential and realized benefits for human nutrition and livelihoods.

• Crop vigor, yield, and quality as indicators of production potential Farmers and researchers commonly report improvements in crop vigor and productivity following soil-health and diversification interventions, including healthier foliage, reduced wilting, more consistent fruit set, and perceived improvements in market quality. While formal yield quantifications may be limited in some studies, participating farmers often self-report gains in productivity linked to integrated soil management and agroecological approaches. These yield-related assessments are frequently complemented by qualitative observations of crop performance under varying management practices and climatic conditions.
• Pollination and biodiversity as drivers of production and stability A substantial portion of evidence emphasizes the role of pollinators in sustaining crop yields and quality, with findings indicating positive relationships between crop yield and pollinator abundance. The magnitude of these effects can be influenced by management practices and climate, highlighting the need for landscape-scale actions to bolster wild pollinator populations in addition to managed pollinators such as honeybees. The provision of floral resources and habitat diversity is cited as a strategic lever to support pollination services and, by extension, food security outcomes.
• Soil biodiversity, soil health, and nutrient cycling as foundational outcomes The concept that “soil is where food begins” frames measurement of soil biodiversity and health as foundational to food security. FAO-linked discussions emphasize four dimensions of food security (production, stability, access, and utilization) each of which can be influenced by soil-resource management that supports nutrient availability, disease suppression, and resilient production systems. While detailed metrics vary, indicators such as soil organic matter, nutrient status, and microbial diversity are commonly linked to downstream measures of crop performance and diet quality.
• Marine and coastal biodiversity outcomes for nutrition and access In the context of reef ecosystems and coastal fisheries, restoration and sustainable management are framed as pathways to increase sustainable food quantities and improve access to nutrient-rich marine foods. Studies emphasize that recoveries in reef fish stocks can contribute to calcium, iron, zinc, vitamin A, and other micronutrients in coastal diets, but equitable access and avoidance of social or institutional barriers are essential to realize these nutrition benefits.
• Economic and policy-relevant metrics Beyond biophysical outputs, governance and policy contexts are reflected in measures related to management effectiveness, enforcement, and the creation of incentives that align farming or fishing practices with biodiversity conservation and food security goals. The literature notes that the timing and scale of investments (such as reducing short-term fishing pressure or expanding alternative livelihoods) shape the realized food security gains and the distribution of benefits across communities. In sum, conservation outcomes commonly measured for food security span:

(1) agronomic outputs such as crop vigor and yield/quality;

(2) ecological services including pollination and biodiversity provisioning;

(3) soil health and nutrient cycling;

(4) nutrition-relevant supply from marine and coastal ecosystems; and

(5) governance, access, and equity dimensions that determine whether observed ecological gains translate into tangible food and nutrition benefits for households and communities.

Policy, Governance, and Implementation Frameworks

Policy and governance gaps introduce risk to biodiversity-based food security. Fragmented institutions, weak cross-sector coordination, unclear tenure arrangements, and limited integration of ecosystem health into fisheries and aquaculture policy often yield unsustainable outcomes. Coastal regulation may exist in law but is not always matched by enforcement, local participation, or ecosystem-based planning, underscoring the need to strengthen cross-sectoral governance and align conservation with livelihood needs. What Works: Integrating Mangroves into Food System Solutions emphasizes the value of incorporating Indigenous and Local Knowledge (ILK) alongside scientific assessments to evaluate pollination services, trade-offs, and potential disservices. This approach also notes the importance of policy trade-offs in selecting response options and highlights the necessity of integrating nature-based solutions into broader food-system governance to bolster resilience and sustainability. Pollinator and food production policies, as outlined in the IPBES framework, stress capacity-building and improving the science–policy interface. They advocate prioritizing financial and other support for the highest-priority needs and ensuring that assessments cover multiple dimensions (ecological, social, and economic) to support transformative governance in agriculture and pollination services. A holistic, governance-centric lens is thus needed to harmonize agroecological transitions with policy instruments, market incentives, and community governance structures. Agroecology and sustainable agriculture frameworks provide a practical governance pathway. Truly sustainable approaches call for holistic integration of ecological, social, and economic dimensions within an enabling governance environment. This includes recognizing the potential of agroecology to deliver resilience, food security, and equitable livelihoods by combining diversified farming practices, participatory governance, and context-specific policy support, while also addressing existing structural lock-ins that favor conventional industrial agriculture. Capacity building and monitoring are critical to successful implementation. The HLPE and related assessments emphasize building capacity to improve the science–policy interface and to secure funding for priority needs related to biodiversity, restoration, and sustainable agriculture. They also highlight the need for standardized monitoring and data-sharing to document successes and failures, enabling timely inputs to managers and policymakers, and for establishing knowledge repositories to store restoration outcomes. Capacity-building initiatives (such as extending extension services and promoting awareness of ecosystem benefits) are associated with greater uptake of agroecological practices and improved farmer well-being in rural landscapes. Across these strands, strengthening regional networks and intra-regional collaboration is identified as a lever to accelerate implementation. The SE Asian context demonstrates that collaboration among neighboring countries, as well as with external western partners, can enhance knowledge sharing, align restoration targets, and sustain funding flows. Yet the evidence also suggests prioritizing deeper collaboration within SE Asia to build more sustainable, self-reinforcing networks that reduce dependence on external actors. In sum, effective biodiversity protection for sustainable, high-quality food requires integrated governance that couples cross-sector coordination, rights-based tenure arrangements, and enforceable regulations with robust capacity building, indigenous knowledge integration, and standardized monitoring. By embedding these elements in policy and practice, this framework aims to translate biodiversity gains into resilient food systems and improved livelihoods.

Economics and Financing

Economic considerations are central to shaping agricultural systems that conserve biodiversity while sustaining food production. Evidence indicates that biodiversity loss is accelerating and largely driven by agricultural practices, highlighting the need for reforms in incentives and investment. In particular, price signals and market access play a crucial role: the ability to access price-differentiated markets that reward agroecologically produced crops is identified as an important requirement for higher profitability and broader adoption of biodiversity-friendly practices. Smallholders emerge as a focal point in financing discussions. Analyses of farm-level productivity and biodiversity outcomes suggest that smallholders can be both productive and beneficial for biodiversity, yet require policy support to translate their ecological stewardship into viable livelihoods. As one study notes, “smallholders are both productive and stewards of biodiversity,” and policy measures that reward these producers could help align livelihoods with conservation goals. Development assistance for smallholders is framed as imperative for expanding food production and biodiversity benefits, with calls for increased investments to meet Sustainable Development Goal targets related to livelihoods and productivity. Beyond traditional grant-based support, blended finance mechanisms are proposed as a pathway to mobilize investment for biodiversity-friendly agriculture. Initiatives such as blended-finance funds aim to unlock major, return-seeking investments to promote conservation and restoration in developing regions, including efforts to sustain gains during shocks and crises. Such mechanisms can finance innovations in sustainable fisheries, alternative fertilizers, and community-led conservation projects, serving as demonstrations that can scale if successful. Empirical research also points to potential profitability gains from biodiversity-friendly farming practices. Some studies report that biodiversity-friendly practices can deliver notable improvements in net profits through reduced input costs and more stable yields, with additional upside from premium markets and potential government incentives. These financial benefits help reconcile conservation with profitability and may lower perceived trade-offs between production and biodiversity. However, achieving these outcomes requires addressing structural barriers that hinder adoption. Analyses highlight lock-ins in the current industrial-agriculture paradigm, including sectoral path dependencies, export-oriented state strategies, subsidies for specific commodity crops, consumer expectations for cheap food, and short-term planning horizons. Overcoming these barriers may require price signals, targeted subsidies, and policy reforms that are more supportive of diversified, ecologically sound production systems rather than solely maximizing immediate yields. In parallel, data and measurement challenges complicate the economics of biodiversity in agriculture. The lack of high-quality data, standards, and technologies for monitoring biodiversity and the effects of conservation actions can hinder investment decisions and evaluation of outcomes. Efforts to combine direct monitoring with indirect indicators of ecosystem health are suggested to produce robust evidence that can inform finance and policy. Finally, finance policy experimentation includes targeted investments in alternatives to harmful inputs. For example, initiatives supporting locally produced, non-synthetic fertilizers address both fertilizer cost volatility and environmental concerns, illustrating how financial instruments can contribute to resilient, biodiversity-friendly agricultural systems while reducing vulnerability to global supply shocks.

Monitoring, Data, and Decision Support

Effective protection of biodiversity to sustain abundant, high-quality food for all requires integrated monitoring, robust data collection, and decision-support tools that translate ecological insights into practical actions. Recent assessments emphasize standardized data collection across scales, the inclusion of unpublished datasets to reduce publication bias, and the replication required to detect reliable effects of biodiversity on pollination and pest control services in agroecosystems. Data collection efforts have prioritized measuring pollination and pest-control services in paired field comparisons (fields adjacent to floral plantings versus control fields without plantings) and have often required a minimum level of replication (for example, at least six fields per study, with three fields containing plantings and three without) to ensure robust inferences. In parallel, monitoring programs have advocated for the development of open information services and interoperable data platforms, drawing on tools designed for rapid data capture and sharing in diverse agricultural contexts (e.g., open data kit concepts and related information systems) to support scalable policy-relevant analyses. Such data infrastructures facilitate the integration of biodiversity monitoring with agricultural outcome metrics, supporting both historical synthesis and near-real-time decision-making. Data analysis frameworks accompanying monitoring efforts stress the need to identify appropriate data sets through comprehensive literature searches and active data-holding networks, including engagement with researchers to locate unpublished data that can mitigate file-drawer biases and broaden the evidence base. This approach is complemented by the development of policy-relevant reporting formats, such as assessment chapter structures and summaries for policymakers, which organize complex data into actionable insights while acknowledging uncertainties and gaps (e.g., background on pollinators, pollination, and food production; and policy-oriented summaries). Beyond data collection and analysis, decision support benefits from consolidated biodiversity monitoring repositories and standardized monitoring tools that enable consistent tracking of restoration and land-management interventions. For example, regional assessments underscore the importance of having mutually accessible knowledge repositories and shared methodologies to document restoration outcomes, ensuring data are comparable across sites and over time. The integration of biodiversity data with ecosystem-service indicators supports scenario analyses, enabling policymakers to evaluate trade-offs and co-benefits of conservation and agricultural practices under varying environmental conditions. Emerging technologies reinforce monitoring capabilities, with environmental DNA (eDNA) metabarcoding and remote sensing highlighted as complementary approaches to traditional methods. These techniques offer rapid, non-destructive means to document species presence and habitat dynamics, providing timely inputs for adaptive management while reducing labor and cost burdens associated with conventional field surveys. Combined with spatial data on land cover, protected areas, and habitat connectivity, such tools support regionally scaled decision-support systems that align biodiversity conservation with food-security objectives. In operational terms, effective monitoring, data curation, and decision support require ongoing capacity-building, funding, and governance structures to maintain data quality, ensure open access, and translate scientific findings into practical guidelines for farmers, extension services, and policymakers. The integration of these components (systematic data collection, transparent analysis, and user-friendly decision-support platforms) forms a resilient foundation for safeguarding biodiversity and, in turn, securing high-quality food for current and future generations.

Case Studies and Lessons Learned

Case studies across agriculture and coastal systems illustrate how biodiversity protection can support abundant, high-quality food for humanity while enhancing resilience. In pollination biology, larger-scale evidence shows that increasing pollinator densities through ecological intensification and habitat conservation can substantially boost global crop yields, though the gains depend on landscape context and the presence of wild pollinators. Conversely, reliance on honeybees alone may partly compensate for wild pollinator losses in some areas, underscoring the need for landscape-scale actions to bolster wild pollinator populations. Intercropping and diversification practices (such as polycultures and agroforestry) have demonstrated improvements in yield stability and resilience to drought, with interactions among crop diversity, pollination, and climate shaping yield dynamics. Intercropping can enhance yield stability more consistently than single-practice approaches, while agroforestry and intercropping combine trees and crops to bolster productivity and ecological balance. These findings emphasize the value of functional biodiversity in mitigating climate-related risks and maintaining food security. Restoration and management of aquatic and coastal ecosystems are also highlighted as pathways to secure food production and biodiversity. Oyster reef restoration, for example, shows variable outcomes but has the potential to increase nekton abundance and oyster production, with success differing by habitat type and salinity gradients; subtidal zones and polyhaline conditions tend to fare better than intertidal or lower-salinity contexts, informing site selection and management priorities for restoration projects. In marine contexts, sustainable aquaculture, improved fisheries management, and ecosystem restoration are framed as critical components of resilient food systems at coastal scales. Soil health and microbiome management emerge as foundational to long-term productivity. Healthy soils (driven by active microbial communities) support nutrient cycling, disease resistance, and crop health, and omics-based approaches are increasingly used to characterize and manipulate soil microbial diversity to sustain yields while reducing external inputs. The shift toward ecological intensification highlights soil microbiome enrichment as a nature-based solution to maintain productivity and environmental sustainability. Across domains, case-study syntheses stress that preserving and leveraging biodiversity for food security requires context-specific, participatory approaches. Agroecology emphasizes locally adapted, knowledge-rich strategies that engage farmers and communities in managing soil, crops, and landscapes to maintain adaptive capacity amid global change. Overall, lessons point to integrating pollinator conservation, diversified farming systems, restoration of key habitats, and soil microbiome management as complementary strategies for achieving abundant, high-quality food while safeguarding biodiversity.

Challenges, Critiques, and Uncertainties

Advancing biodiversity conservation to support abundant, high-quality food faces several persistent challenges, critiques, and areas of uncertainty that complicate translation into policy and practice. While agroecological approaches and ecological intensification are increasingly recognized, there remains substantial confusion about definitions, scope, and expected benefits, which can hinder implementation and public acceptance.

• Conceptual ambiguity and misperceptions: Even as agroecology gains prominence in international and national discourse, questions and misinterpretations about what agroecology entails and the benefits it offers remain widespread, complicating evidence-informed decisions. This includes debates over trade-offs versus synergies between agricultural intensification and biodiversity conservation, and the practical implications for food systems transformations.
• Trade-offs between production and biodiversity: A core challenge is reconciling short-term yields with long-term biodiversity outcomes. Some evidence suggests that nature-based and agroecological approaches can deliver multiple ecosystem services, contradicting simple dichotomies of trade-offs, but generalizing these results across diverse systems remains uncertain. In intensive landscapes, targeted restoration and diversification may support more specialized pollinators, yet scaling these benefits broadly requires careful design and governance.
• Evidence gaps and variability across landscapes: While several studies highlight potential synergies, there are gaps in knowledge about how specific practices translate to biodiversity gains and food security under variable climatic and socio-economic conditions. The magnitude and durability of benefits from conservation agriculture, habitat restoration, and agroforestry depend on local context, requiring robust, place-based assessment and monitoring.
• Policy, governance, and implementation uncertainties: Translating scientific findings into policy involves navigating governance arrangements, stakeholder engagement, and framing of options to avoid unintended consequences. The literature notes ongoing questions about how to best communicate risks and benefits, design effective incentives, and ensure data transparency and reproducibility in policy-relevant research.
• Data limitations and methodological biases: Several assessments emphasize limitations such as reliance on published studies with potential publication bias toward significant findings, and the challenge of capturing broader welfare and well-being impacts alongside ecological outcomes. These limitations underscore the need for comprehensive data collection, standardized metrics, and open data practices to support robust decision-making.
• Pesticides and non-target effects: Research synthesizing pesticide exposure across species indicates widespread harm to growth, reproduction, and behavior in many taxa, highlighting a key uncertainty area for balancing pest management with biodiversity protection. While the evidence demonstrates significant risks, extrapolating to all species and contexts remains challenging, reinforcing the push toward integrative pest management and reduced chemical reliance.
• Conflicts of interest and communication challenges: The process of evaluating and communicating complex ecological interventions can be affected by perceptions of conflicts of interest or inconsistent messaging, which may influence stakeholder trust and policy uptake. Transparent governance, clear attribution of contributions, and careful framing of results are essential to maintain credibility.
• Monitoring, evaluation, and learning needs: Implementing biodiversity-forward food systems requires ongoing monitoring of ecological and social outcomes, adaptive management, and clear indicators linking biodiversity to food security. The absence of long-term, comparable datasets can impede learning and the scaling of successful practices.

Future Directions

Efforts to safeguard biodiversity while ensuring abundant, high-quality food for the future should focus on integrated, multi-level strategies that combine ecological restoration, sustainable agricultural practices, and enabling policy and governance frameworks.

• Targeted policies and governance reforms
• Realign and coordinate existing policies across sectors to include financing, investments, and clear objectives for biodiversity and ecosystem restoration, with an overarching coordinating body to guide implementation and monitoring. Strengthening cross-sectoral governance and aligning conservation with livelihood needs is critical to addressing these interconnected risks. Policy frameworks should treat mangrove restoration as a component of national development, integrated into local coastal management plans and aligned with national climate and development targets (e.g., NDCs).
• Upscale mangrove restoration through ambitious, science-based protocols and enhanced regional coordination, leveraging existing ASEAN mechanisms to harmonize policies across countries.
• Ecological restoration and ecosystem services
• Prioritize community-based ecological mangrove restoration (CBEMR) tied to livelihoods, which has shown promise for sustainable, long-term restoration when local users participate in planning, monitoring, and governance and can realize tangible benefits through fisheries, aquaculture, or nature-based enterprises.
• Recognize the role of restoration within coastal rehabilitation plans to enhance coastal protection, carbon storage, and biodiversity, particularly in the face of extreme climatic events; ensure restoration projects are designed to deliver multiple ecosystem services rather than carbon offsets alone.
• Expand blue carbon and remote-sensing approaches to monitor restoration outcomes and guide adaptive management at landscape scales.
• Agroecology and resilient food systems
• Promote agroecological diversification as a pathway to climate resilience and low-emission food systems, emphasizing diversification across agro-pastoralism, agroforestry, and landscape-scale farming to buffer climate shocks and sustain yields. This involves integrating multiple livelihoods and improving soil health to enhance water holding capacity and yield stability under variable conditions.
• Recognize the bidirectional relationship between food systems and climate: transform production to reduce emissions while increasing resilience, ensuring that agroecological approaches do not compromise yield, and are scalable through participatory processes.
• Economic incentives and market mechanisms
• Design price-based and market-based instruments (e.g., carbon credits, tax incentives) to reward stakeholders who manage restored mangroves and coastal ecosystems, while disincentivizing activities that damage these systems (e.g., deforestation). Align incentives with long-term restoration goals and with broader climate and biodiversity targets.
• Integrate restoration financing within national development agendas and explore regional financing approaches, including leveraging global frameworks (e.g., CBD targets, SDGs) to secure funding and align with country-specific NDCs.
• Monitoring, data, and learning
• Invest in robust monitoring systems, open data, and interdisciplinary research to evaluate restoration outcomes, biodiversity benefits, and livelihood impacts over longer time horizons, recognizing that many studies indicate the need for landscape-wide evaluations to capture true effects.
• Support knowledge generation on practical bottlenecks to scaling restoration, including governance, community adoption, and market access, to inform iterative improvements and replication in other regions.
• Community engagement and governance innovations
• Emphasize community participation in planning, monitoring, and rule-setting to sustain restoration and protection efforts beyond project cycles, linking ecological outcomes with tangible social and economic benefits.
• Address governance gaps by improving tenure clarity, enforcement of coastal regulations, and integration of ecosystem health into fisheries and aquaculture policy, ultimately supporting sustainable coexistence of biodiversity and food production.
