According to the research conducted by the scientists from the University of Oxford in the UK and the University of Copenhagen in Denmark found that climate change is adversely affecting the production of key crops such as wheat and rice, with some countries faring far worse than others. As per the research, published in the journal PLOS ONE, the world’s top 10 crops namely barley, cassava, oil, maize rice, rapeseed, palm, sorghum, soybean, sugarcane and wheat, supply a combined 83 per cent of all calories produced on cropland. Yields have long been projected to decrease in future climate conditions.
Researchers used weather and reported crop data to evaluate the potential impact of observed climatic change and found that climate change is affecting different areas of global food production differently.
Climate change impact on global food production will be inconsistant such as mostly negative in Europe, Australia and Southern Africa, and generally positive in Latin America, and mixed result in Asia and Northern and Central America.
The study found that half of the food insecure countries are experiencing decreases in crop production and so are some affluent industrialized countries in Western Europe.
In some areas of the upper Midwest US recent climate change has increased the yields of certain crops.
Researchers said that the report has implications for major food companies, commodity traders and the countries in which they operate, as well as for citizens worldwide.
