Climate change\u00a0is adversely affecting the production of key\u00a0crops\u00a0such as\u00a0wheat\u00a0and rice, with some countries faring far worse than others, according to researchers including those of Indian origin.<\/p>\n

The world’s top 10\u00a0crops\u00a0— barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and\u00a0wheat\u00a0— supply a combined 83 per cent of all calories produced on cropland.<\/p>\n

Yields have long been projected to decrease in future climate conditions.<\/p>\n

The research, published in the journal PLOS ONE, shows that\u00a0climate change\u00a0has already affected production of these key\u00a0energy sources.<\/p>\n

Scientists from the\u00a0University of Oxford\u00a0in the UK and the\u00a0University of Copenhagen\u00a0in Denmark used weather and reported crop data to evaluate the potential impact of observed\u00a0climate change.<\/p>\n

They found that observed climate change causes a significant yield variation in the world’s top 10 crops, ranging from a decrease of 13.4 per cent for\u00a0oil palm\u00a0to an increase of 3.5 per cent for soybean, and resulting in an average reduction of about one per cent of\u00a0consumable\u00a0food\u00a0calories from these top 10\u00a0crops.<\/p>\n

“There are winners and losers, and some countries that are already\u00a0food\u00a0insecure fare worse,” said\u00a0Deepak Ray\u00a0of the\u00a0University of\u00a0Minnesota\u00a0in the US.<\/p>\n

“These findings indicate which geographical areas and crops are most at risk, making them relevant to those working to achieve the UN Sustainable Development Goals of ending hunger and limiting the effects of climate change. Insights like these lead to new questions and crucial next steps,” said Ray.<\/p>\n

The impacts of climate change on global\u00a0food\u00a0production are mostly negative in Europe, Southern Africa, and Australia, generally positive in Latin America, and mixed in\u00a0Asia\u00a0and Northern and\u00a0Central America.<\/p>\n

About half of all\u00a0food-insecure countries\u00a0are experiencing decreases in crop production — and so are some affluent industrialised countries in Western Europe, the study found.<\/p>\n

In contrast, recent climate change has increased the yields of certain crops in some areas of the upper\u00a0Midwest US.<\/p>\n

“This is a very complex system, so a careful statistical and data science modeling component is crucial to understand the dependencies and cascading effects of small or large changes,” said\u00a0Snigdhansu Chatterjee\u00a0of\u00a0University of\u00a0Minnesota.<\/p>\n

The report has implications for major food companies, commodity traders and the countries in which they operate, as well as for citizens worldwide, researchers said.<\/p>\n

“The research documents how change is already happening, not just in some future time,” he said.<\/p>\n
