Climate change affects agriculture in a number of ways; including
through changes in average temperatures; rainfall and climate extremes
with an important impact on soil erosion (i.e. floods, drought, etc):
changes in pests and diseases, changes in atmospheric carbon dioxide,
changes in the nutritional quality of some foods, changes in growing
season, and changes in sea level .
Crop yields show a strong correlation with temperature change and with
the duration of heat or cold waves, and differ based on plant maturity
stages during extreme weather events .
Modified precipitation patterns will enhance water scarcity and
associated drought stress for crops and alter irrigation water supplies.
They also reduce the predictability for farmers’ planning . In an indirect way, a change in temperature and moisture levels may lead to a change in the absorption rate of fertilizers
and other minerals, which determine yield output. In short, the rise in
temperature along with the reduction in rainfall reduces agricultural
productivity if both are beyond the threshold that is suitable for crop
production .
