Agriculture is the sector most affected by changes in climate patterns and will be increingly vulnerable in the future. Especially at risk are developing countries, which are highly dependent on agriculture and have fewer resources and options to combat damage from climate change.
In the short term, as the global average temperature rises 1-3, industrialized countries may well gain in food production potential. However, in lower latitudes especially in subsistence sectors, marginal, semi-arid and sub-humid regions, where rain fed agriculture is the norm-even with a minimal rise in global temperature ,cop potential will most probably decline.
