International Model for Policy Analysis and Agricultural Commodity Trade

The IMPACT (International Model for Policy Analysis and Agricultural Commodity Trade) model is designed to examine alternative futures for global food supply, demand, trade, prices, and food security. The model enables users to provide both fundamental, global baseline projections of agricultural commodity supply, demand, trade, prices and malnutrition outcomes along with cutting-edge research results on quickly evolving topics such as bioenergy, climate change, changing diet/food preferences, and many other themes. IMPACT covers over 40 commodities, which account for virtually all of world food production and consumption, including all cereals, soybeans, roots and tubers, meats, milk, eggs, oils, meals, vegetables, fruits, sugar and sweeteners, and other foods in a partial equilibrium framework. It is specified as a set of 115 country-level supply and demand equations where each country model is linked to the rest of the world through trade.
