Natural Resources and Resilience

Climate change, natural resource degradation, and biodiversity loss, all aggravated by growing competition and trade-offs across natural resource systems and food systems, are impeding our ability to meet food demand and nutrition needs, and threatening human and planetary health.

Overview

The Natural Resources and Resilience Unit (NRR) works at the intersection of nature, agriculture, and development to support tangible progress toward more equitable, resilient, and environmentally sustainable food systems that thrive on healthy ecosystems and deliver better nutrition, livelihoods, and economic opportunities for men and women. The highly interdisciplinary research group includes a range of social and biophysical scientists working at local, national, and global scales to tackle the challenge of preserving nature while improving food security and nutrition.

The Unit works with government agencies, NGOs, women’s organizations, and university partners to design and implement policy-relevant research

in areas including behavioral change interventions, participatory institutional analysis, gender-responsive climate change interventions, optimization of water/irrigation-energy-food-environmental systems, economics of biodiversity conservation, and digital innovations in the food systems space. This research uses a gender and social equity lens to address food and environmental system challenges. All of the Unit’s work includes a focus on measurable improvements in the resources, agency, and achievements of the world’s poorest women and men farmers in Africa, Asia, and Latin America.

Areas of Focus

Equitable climate change strategies

Climate change and natural resource degradation impede our ability to meet food demand and nutrition needs. NRR researchers identify, pilot, and conduct impact assessments of gender- and nutrition-sensitive climate adaptation and mitigation strategies. NRR work also supports governance of climate action at multiple scales.

Natural resources–food system nexus

Growing competition and trade-offs across natural resources and food systems affect planetary and human health. To optimize water/irrigation-energy-food-environmental systems, NRR conducts economic analyses of technologies, policies, and institutions that reduce environmental degradation, strengthen resilience, improve food systems, and contribute to women’s empowerment. Researchers also evaluate the impact of behavioral change innovations.

Natural resource management

Biodiversity loss and water, land, and forest degradation affect agroecosystems and all life on Earth. To inform improved resource governance and decision-making, NRR provides economic valuation of biodiversity and environmental services, as well as systems and institutional analyses of natural resource management interventions and governance approaches.

Digital innovations

The growing digital divide increases inequity in use and access to resources and technologies to manage risks. To make the technologies and analytics needed for food system transformation more accessible, NRR researchers assess AI solutions for food and environmental systems, ways to reduce the digital gender gap, and human-centered approaches for designing solutions and testing prototypes.

 Methods and tools

NRR researchers employ a wide range of methods and tools to address resource management, climate, and equity challenges. These include novel resilience metrics and frameworks, economic-environmental modeling and assessments of policy strategies, political economy analyses, institutional analyses, participatory action research, engagement with multistakeholder platforms, real-time agrifood system monitoring, and scenario and trade-off analyses using digital models.

The Russia-Ukraine conflict and global food security

The Russia-Ukraine conflict and global food security

When Russia invaded Ukraine in February 2022, sparking fears of a global food crisis, IFPRI responded rapidly to the need for information and policy advice to address the crisis. From the first moments of the conflict, a new IFPRI blog series provided critical information and insights into the impacts on food security, caused by rising food, fertilizer, and fuel prices and trade disruptions, for vulnerable countries and regions. This book is a compilation of those blog posts, which include analysis of trade flows, tracking of food prices and policy responses, and results of impact modeling. Together, they provide an overview of how the crisis has progressed, how the international community and individual countries responded with efforts to ensure food security, and what we are learning about the best ways to ensure food security in the aftermath of a major shock to global food systems.

Engaging women’s groups to improve nutrition: Findings from an evaluation of the Jeevika multisectoral convergence pilot in Saharsa, Bihar

This report presents the endline findings of an impact evaluation of the JEEViKA Multisectoral Convergence pilot, designed as an effectiveness trial, in one district in Bihar, India. JEEViKA, a rural livelihoods project, supports self-help groups (SHGs) – savings and credit-based groups of about 15-20 women, mostly targeted toward those from poor households – with the aim of improving their livelihoods and enhancing household incomes. The JEEViKA Multisectoral Convergence (JEEViKA-MC) pilot went a step further, leveraging these SHGs to address the immediate and underlying determinants of undernutrition among women and children. The multisectoral convergence model, developed by the Bihar Rural Livelihoods Promotion Society with technical support from the World Bank, was piloted in 12 Gram Panchayats of Saharsa district in Bihar. Two complementary sets of interventions-health and nutrition behavior change communication (BCC) to improve women’s knowledge and household practices, and efforts to improve service access through convergence -were layered onto the existing core package of JEEViKA activities and were targeted to women who were members of the SHGs already formed by JEEViKA. Within this target population, households with young children, mothers of young children, and pregnant women were the primary focus of the JEEViKA-MC pilot.

Show me what you eat: Assessing diets remotely through pictures

Goal: Using real-time smartphone meal pictures sent by rural or urban households to better monitor and assess the quality of their diets, and provide tailored recommendations to improve them. Detailed information on household and individual dietary intake is crucial for adequate nutritional monitoring and designing interventions to improve diets. Common recall-based methods are generally time consuming, costly, and subject to non-negligible measurement errors and potential biases. In addition, the scope of information that can be obtained in a regular survey is typically limited. Detailed diaries, in turn, are effort- and time-intensive and prone to errors. With increasing mobile penetration in both urban and rural areas, meal pictures can overcome some of these difficulties, providing real-time, detailed food intake information of individuals remotely and at a minimal cost. Moreover, pictures can be obtained over extended periods of time, beyond the standard short spans (i.e. 24-hours) in recall survey questions, with little to no data quality loss. Such rich consumption data can help identify and better understand vulnerabilities and nutritional imbalances —including specific macronutrient or micronutrient gaps or excesses—, and open the door for low-cost, individually tailored digital interventions to promote healthier diets. Moreover, crowdsourced data allow to identify locally available, affordable foods rich in specific nutrients consumed by similar households in the area. Interventions, in turn, can be delivered through text messages, interactive voice response (IVR), or phone calls, or videos or interactive games integrated into an app, benefitting from a two-way communication channel with individuals.
