|Description=Expansion of agriculture is one of the most important and visible alternations of the natural environment, leading to greenhouse gas emissions, loss of biodiversity and ecosystem services, and nutrient imbalances. It is driven by the production of food, feed for livestock, fibers and other products, bio-energy and timber, resulting from domestic demand and trade in these products. In IMAGE, demand and trade are based on external projections of demographic and economic development, technological change, policy scenarios, and resource availability. Changes in income and population lead to a changing demand for agricultural commodities. This induces a change in the supply, which also depends on the resource availability and the efficiency of natural resource use. This efficiency can change as a result of technological change and substitution between production factors. | |Description=Expansion of agriculture is one of the most important and visible alternations of the natural environment, leading to greenhouse gas emissions, loss of biodiversity and ecosystem services, and nutrient imbalances.
