GlobalWarming Awareness2007
Global warming is projected to have significant impacts on conditions affecting agriculture, including temperature, precipitation and glacial run-off. These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and domesticated animals. Any short-term fluctuations of the climate can have dramatic effects on the agricultural productivity. Thus, the climate has a direct influence on food supply. Rising carbon dioxide levels would also have effects, both detrimental and beneficial, on crop yields.
A positive effect of rising carbon dioxide concentrations would be increased agricultural yields, because of the role of carbon dioxide in photosynthesis. The overall effect on agriculture will depend on the balance of the beneficial and detrimental effects.
Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production.
