Global analysis reveals persistent shortfalls and regional differences in availability of foods needed for health

Global analysis reveals persistent shortfalls and regional differences in availability of foods needed for health

Sufficient food is available in the world for all people to consume sufficient calories, but not healthy diets. This study traces historical and projected changes in global food systems toward alignment with the new Healthy Diet Basket (HDB) used by UN agencies and the World Bank to monitor the cost and affordability of healthy diets worldwide. Using the HDB as a standard to measure adequacy of national, regional and global supply-demand balances, we find substantial but inconsistent progress toward closer alignment with dietary guidelines, with large global shortfalls in fruits, vegetables, and legumes, nuts, and seeds, and large disparities among regions in use of animal source foods. Projections show that additional investments aimed at reducing chronic hunger would modestly accelerate improvements in adequacy where shortfalls are greatest, revealing the need for complementary investments to increase access to under-consumed food groups especially in low-income countries.

Report

Strategic modeling for future agriculture in Asia

2025Cenacchi, Nicola; Sulser, Timothy B.
Details

Strategic modeling for future agriculture in Asia

This APO report pinpoints the declining agricultural productivity situation in APO economies since 2019 and explores how key measures could accelerate progress achieving food security and mitigating undernourishment by improving calorie availability per person. Key challenges include slowed agricultural productivity, climate change, land degradation, insufficient R&D investment, water scarcity, and inefficiencies in markets. The report examines measures such as policy interventions and investments in R&D, irrigation, and water use efficiency to enhance productivity, food security, and sustainable resource use. Such measures could accelerate progress toward achieving food security and mitigating undernourishment by improving calorie availability per person.

The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT): Model documentation for version 3.6

The International Food Policy Research Institute’s IMPACT model is a robust tool for analyzing global and regional challenges in food, agriculture, and natural resources. Continuously updated and refined, IMPACT version 3.6 is the latest update to the model for continuously improving the treatment of complex issues, including climate change, food security, and economic development. IMPACT 3.6 multimarket model integrates climate, crop simulation, and water models into a comprehensive system, providing decision-makers with a flexible platform to assess the potential impacts of various scenarios on biophysical systems, socioeconomic trends, technologies, and policies.
