India’s agrifood system: Structural features and policy priorities

Malawi: Cost effective options for inclusive and sustainable development

In this policy brief, we present findings of a systematic evaluation and ranking of investment options for Malawi’s agrifood system based on their cost-effectiveness in achieving multiple development outcomes, including agrifood gross domestic product (GDP) growth, agrifood job creation, poverty reduction, declining undernourishment, and lowering diet deprivation. Additionally, the study assesses their environmental footprint, focusing on water consumption, land use, and emissions. Investments in small and medium enterprise (SME) processors, seed systems, and farmers credit are shown to be the most cost-effective at driving improvements in social outcomes, like poverty and undernourishment. They are also highly ranked in terms of expanding agrifood GDP and employment. Investments in extension and advisory services for livestock, SME traders, and seed subsidy also rank high. However, many cost-effective investments have relatively high environmental footprints, which highlights potential tradeoffs. The study further reveals shifts in the cost-effectiveness ranking of in vestment options overtime and when extreme production shocks occur.

Achieving transformational sustainable land Intensification: Integrated general equilibrium and portfolio analysis for Senegal

Feeding a growing global population while conserving natural resources remains a central challenge of Sustainable Intensification (SI). Despite decades of SI efforts, cropland expansion in many developing countries continues to accelerate, contributing to deforestation and biodiversity loss. Even with observed increases in crop yields, studies suggest that farmers continue to expand cropland, underscoring the need to consider market dynamics and the economywide effects of productivity gains. This study offers a new perspective on achieving transformational sustainable land intensification by treating farming activities as investment decisions shaped by risk and return under production and markets uncertainties. Unlike the traditional SI strategies that focus on efficiency gains through improved inputs or agronomic practices, we apply an optimal portfolio analysis to cropland allocation, aiming to enhance farming efficiency by considering market interconnections across sectors. Using Senegal as a case study, we demonstrate that adopting an optimal diversification strategy on new cropland investment could reduce land expansion needs by up to 68 % by 2030. This strategy not only helps mitigate emissions and reduce water footprint but also enhances crop biodiversity. Socioeconomic and environmental benefits are found to be greater when the country promotes high-value crops in its portfolio, such as fruits and vegetables, compared to grain crops. Our findings also contribute to ongoing debates around land-sparing versus land-sharing strategies and offer new insights into the drivers of cropland expansion in light of current global land use patterns.
