Climate change affects food production unevenly
The world's top 10 crops – barley, cassava, corn, oil palm, rapeseed, rice, sorghum, soybeans, sugar cane and wheat – collectively provide 83 percent of all calories produced in crop lands, But revenues are expected to fall in future climate conditions.
According to the site "phys", new research shows that climate change has already affected the production of these major energy sources, and some regions and countries much worse than others.
The study conducted by the University of Minnesota, conducted with researchers from Oxford University and the University of Copenhagen, used weather data and reported crops to assess the potential impact of observed climate change.
The researchers found these results:
• Climate change is marked by a significant variation in the world's top 10 energy crops, ranging from a 13.4% reduction in palm oil to a 3.5% increase in soybeans, resulting in an average reduction of 1% of the dietary calories consumed from the top 10 crops , The effects of climate change on global food production are mostly negative in Europe, South Africa and Australia, generally positive in Latin America and mixed in Asia, North and Central America.
• Half of food-insecure countries suffer from a decline in crop production, as are some of the richest industrialized countries in Western Europe.
• On the other hand, recent climate change has increased certain crops in some parts of the western upper part of the United States.
"There are winners and losers, and some countries that are already suffering from food insecurity are worse off," said Deepak Ray of the University of Minnesota's Institute of the Environment, lead author of the study.
These results indicate that the answer to the question "How global crop production changes over time" shows the geographical areas and the most vulnerable crops, supporting the achievement of sustainable development goals at the United Nations to eliminate hunger and reduce the impacts of climate change.
