Descripción
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 since its initial development in the early 1990s, IMPACT version 4 represents the latest iteration of the model, offering an enhanced treatment of complex issues such as climate change, food security, and economic development. IMPACT 4 modeling system 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.
