Climate change affecting global food production: Study

Date: 04 June 2019 Tags: Climate Change

According to recently released research in ournal PLOS ONE, climate change is adversely affecting the production of key crops such as wheat and rice. The research was based on study conducted by scientists from University of Oxford in UK and the University of Copenhagen in Denmark. They had used weather and reported crop data to evaluate the potential impact of observed climate change.

Key Findings of the study

  • The world's top 10 crops - barley, maize, cassava, oil palm, rice, sorghum, rapeseed, soybean, sugarcane and wheat -supply a combined 83%% of all calories produced on cropland.
  • Climate change has caused significant yield variation in world's top 10 crops, ranging from a decrease of 13.4%% for oil palm to increase of 3.5%  for soybean, and resulting in an average reduction of about 1  of consumable food calories from these top 10 crops.
  • The impacts of climate change on global food production are mostly negative in Europe, Southern Africa, and Australia, positive in Latin America, and mixed in Asia and Northern and Central America.
  • About half of all food-insecure countries are experiencing decreases in crop production and also some affluent industrialised countries in Western Europe.
  • In contrast, recent climate change has increased the yields of certain crops in some areas of the upper Midwest United States.
