(i) Climate change is likely to cause stronger storms and more floods, which can damage crops.


(ii) Droughts caused by climate change could reduce the amount of water available for irrigation.


(iii) The crops that are grown for food need specific conditions to thrive, including the right temperature and enough water. A changing climate could have both positive and negative effects on crops.


For example, the northern parts of the United States have generally cool temperatures, so warmer weather could help certain crops grow.


In southern areas where temperatures are already hot, even more heat could hurt crop growth.


(iv) Higher temperatures and changing rainfall patterns could help some kinds of weeds and pests to spread to new areas.


(v) Other than the effect of high and low rainfall on cropping patterns, it is predicted that phenomena such as coastal flooding will reduce the amount of land available for agriculture.


(vi) El Nino provides another example of how agricultural production patterns and food securities are impacted. In Southern Africa (2016), it severely weakened crop prospects, triggering a 25% cut in wheat production. In India too, following a poor monsoon, the area of wheat crop was cut.
