Description:
Attempts to seriously investigate the impacts of potential changes in climate due to increased greenhouse gases dates to the mid- to late 1980's. Some of the advances in impact analysis since the first studies: 1) Explicit modeling of adaptation within the farm sector. 2) Consideration of agriculture as a global system that interacts through trade in agricultural products and input flows. Some work has been done but more is needed on: 1) How government policies and programs - ranging from crop insurance and disaster assistance to acreage reduction programs, tariffs and quotas, water pricing, and the level of agricultural research - will affect the response of the farm sector. 2) Consideration of climate change as only one of many forces along with changes in population, economic activity, and technology that will shape the agricultural economy over the coming decades. 3) Explicit consideration of the high levels of uncertainty in climate change prediction and the implications for adaptation of high levels of natural variability in weather. 4) Modeling of competition for land, water, labor, and capital as other sectors of the economy are affected by climate change
