Degradation of soil and water resources is one of the major challenges for global agriculture. Climate change will further alter agricultural systems with substantial consequences for food production. The risk of redu ced food yields is greatest in developing countries, where 790 million people are estimated to be undernourished at present.
In India, it is currently predicted that while overall rainfall may not experience a significant change, the temporal and spatial distribution may change.

If agricultural production goes down, the price of staple food commodities will increase (see table : Plummeting production).
