Demand for and production of agricultural products are modelled by the soft-linked agro-economic models [[MAGNET model|MAGNET]] or alternatively [[IMPACT model|IMPACT]] (Component [[Agricultural economy and forestry]]). The IMAGE crop and land-use models supply information to MAGNET on land supply by region and changes in potential yields. MAGNET provides information on future agricultural production levels and intensity by region, matching regional demands through trade. MAGNET assesses production of agricultural products based on combinations of primary (land, labour, capital and natural resources) and intermediate production factors. For the livestock sector, IMAGE makes scenario-specific assumptions about livestock production in different systems (Component [[Livestock]]). A key purpose of the agro-economy model is to determine regional production levels and the associated yields and livestock efficiencies, taking into account changes in technology and biophysical conditions. An increase in demand for agricultural production can be met by land expansion (using the regional land supply curves) and/or intensification of land use and increasing yields. IMAGE 3.0 also calculates timber demand and forest management (Component [[Forest management]]).
