Ecosystem Services and Biodiversity

Ecosystem services are the benefits people obtain from ecosystems, including many that are essential for agricultural production and food, such as water supply, pollination, and climate regulation. Biodiversity is the variety of life at genetic, species, and ecosystem levels, and plays a key role in ecosystem services. For instance, soil fertility, pollination, and natural pest control are examples of biodiversity-mediated ecosystem services that are critical to crop production. How crops and agricultural lands are managed and maintained can have positive—or negative—effects on ecosystem services and biodiversity.

IFPRI research provides much-needed insight into how the dual goals of food and nutrition security and ecosystem health can be included in the decision-making of farmers, communities, and policymakers. To inform policies and local governance that promote sustainability and inclusion, IFPRI engages in policy-relevant research on valuing and modeling ecosystem services, assessing the relationship between biodiversity-mediated ecosystem services and land use and management choices, informing community-based conservation, and supporting self-governance of common pool resources, including designing, testing, and scaling natural resource management games for research and experiential learning. IFPRI’s research on ecosystem services and biodiversity uniquely pays attention to gender and institutions.

IFPRI’s ecosystem services and biodiversity research is closely aligned with the Sustainable Development Goals (SDGs), including SDG 15, and the CGIAR Impact Areas on Climate Adaptation and Mitigation; Environmental Health and Biodiversity; and Poverty Reduction, Livelihoods, and Jobs.

Economic valuation of ecosystem services of selected interventions in agriculture in India

Economic valuation of ecosystem services of selected interventions in agriculture in India

Agriculture is multi-functional, producing economic goods including food, feed, fibre, and fuel, as well as providing several intangible or non-tradable services to society free of cost. Non-tradable services, unlike economic goods, remain unpriced; as a result, farmers are not compensated monetarily for the benefits of the several non-tradable services they provide through agriculture. Recognizing the monetary value of non-tradable ecosystem services is crucial to incentivize farmers to adopt eco-friendly technologies and practices for the sustainable development of agriculture. Through a meta-analysis of the existing evidence on ecosystem services, this study attempts to estimate the value of ecosystem services by using direct and indirect valuation methods—for example, carbon sequestration, methane emission, nutrient availability, biological nitrogen fixation, and water saving—generated by several important technological and agronomic interventions, namely the direct seeding of rice (DSR), zero-tillage in wheat, leguminous crops, organic manure, integrated nutrient management, and agroforestry, based on studies conducted in India. It also explores the trade-offs between the non-tradable and tradable ecosystem services attributable to these interventions. The monetary value of the non-tradable services resulting from most of these interventions is quite large, 34–77% of the total value of all the ecosystem services. However, not all interventions result in a win-win situation that yields improvements in both tradable and non-tradable outcomes. While no-till wheat, legumes, and integrated nutrient management result in a win-win outcome, there are trade-offs between the tradable and non tradable ecosystem services in the cases of directed seed rice, organic manure, and agroforestry. This evidence suggests that not all agricultural technologies and practices are beneficial for farmers, despite their higher environmental benefits. Thus, the findings of this study imply that agricultural policy should provide incentives for the adoption of technologies and practices to conserve ecosystems and natural resources.

Using best-worst scaling to inform agroecological interventions in Western Kenya

Using best-worst scaling to inform agroecological interventions in Western Kenya

Both the demand for food and the environmental impacts of food production are estimated to significantly increase by 2050. Agroecological interventions have proven effective in facilitating the transition from current food production systems to more sustainable ones. These interventions can not only ensure more equitable food and nutritional security but also address poverty and reduce environmental impacts. As such, agroecological interventions can generate both private and public ecosystem services. Farmers play a key role in how food is produced, as the practices they use are linked with their preferences and expertise, as well as the constraints they face. Understanding farmers’ preferences for the adoption of different agroecological practices and their perceptions of the associated costs and benefits is critical to informing policies that can effectively support farmers in transitioning to more sustainable practices, including those that contribute to the generation of ecosystem services highly valued by broader society. To assess such preferences, we conducted a survey among farmers in Western Kenya which included a best-worst scaling experiment augmented by qualitative questions about the reasons for farmers’ views about the importance of the benefits arising from agroecological practices. Results show that farmers have strong preferences for adopting agroecological practices that generate private goods and are directly related to increasing productivity and food security, including improving health of household members. These may also include practices that have some public good elements as well, such as increasing agrobiodiversity. However, practices that generate broader public good benefits, including improved forest quality/coverage, reduced off-farm environmental impacts, greater community-level resilience to shocks, and improved landscape and wildlife management, were less important to farmers. Such findings can be used to inform policies that support farmer adoption of agroecological interventions best suited to different farming communities, as well as indicating the need for additional types of market-based incentives, such as through Payments for Ecosystem Service mechanisms.

Ecosystem services may provide large economic values in Kenya and Vietnam: A value transfer application based on results from a systematic literature review

This study focuses on the valuation of ecosystem services in Kenya and Vietnam, two countries that have received much attention from the international development community for their biodiversity significance, opportunities for scaling, climate and poverty challenges, and political will. Using The Economics of Ecosystems and Biodiversity (TEEB) framework and the Millenium Ecosystem Assessment (MEA), this study estimates per hectare values of ecosystem services in Kenya and Vietnam based on a systematic literature review of studies on the values of ecosystem services in both countries. Provisioning services, such as medicines, timber, and non-timber forest products were better studied than regulating, supporting and cultural ecosystem services, underscoring the need for further research to better estimate the values of non-tangible services which would improve the estimation of total value of ecosystem services in Kenya and Vietnam. To complement the national level analysis, we selected forest biomes to conduct a value transfer analysis. Forests provide ecosystem service benefits worth $25.78 billion for Kenya and $35.6 billion in Vietnam in 2022 USD. In comparison, the agricultural sector contributed $48.50 billion to Vietnam’s GDP and $24.10 billon to Kenya’s GDP in 2021. The per hectare values for ecosystem services are used in a value transfer analysis to estimate the total value of forest ecosystem services in Vietnam and Kenya. The average per hectare value of ecosystem services provided by forests in Kenya is $5,718.50 ha−1 yr−1 estimated within a range spanning $1,609.44 to $15,606.62 ha−1 yr−1 , while Vietnam’s forests demonstrate an average value of $3,650.20 ha−1 yr−1 , with a range of $84.93 to $8,978.16 ha−1 yr−1 . We project the loss of forests into 2050 and estimate the annual economic loss of ecosystem services at $48.08 million for Kenya and $76.29 million for Vietnam, respectively, if deforestation and forest degradation continue at the current rates. Our approach presents a comprehensive overview of diverse ecosystem services, equipping policymakers with a nuanced comprehension of ecosystems’ inherent value. By consolidating values from the literature into a national-level estimate, we provide compelling evidence at a broader scale for informed decision-making. Despite the well-known limitations of value transfer method and with caveats, the values presented in our paper can provide a guiding reference for incorporating these estimations into broader policymaking endeavors.
