A 7.2 Fahrenheit (4 Celsius) increase in temperature, which scientists expect by 2100 if global warming continues on its current trajectory, reduces average yields by 31.5 per cent, said the report.[...]

The world's supply of vegetables could fall by more than a third by 2050 unless urgent action is taken to combat climate change, according to a new study. Global average yields of common crops such as soy beans and lentils are set to decrease as a result of increased temperatures and water shortages, it is claimed.[...]

By Lin TaylorLONDON, June 11 (Thomson Reuters Foundation) - Keepinghealthy could become more costly as climate change and waterscarcity cause a huge drop in the global production ofvegetables and legumes, scientists said on Monday.The amount of vegetables produced could fall by more than athird, especially in hot regions like southern Europe andswathes of Africa and South Asia, said researchers from theLondon School of Hygiene and Tropical Medicine.By analysing studies across 40 countries, with some datingas far back as 1975, they found that hikes in greenhouses gases,water scarcity and global temperatures lowered the amount ofvegetables and legumes produced.Such drastic changes could drive up the prices ofvegetables, which would affect poorer communities the most,according to the study, which was published in the Proceedingsof the National Academy of Sciences."If we take a 'business as usual' approach, environmentalchanges will substantially reduce the global availability ofthese important foods," said Alan Dangour, a co-author of thepaper, which is the first of its kind, in a statement.Scientists have warned that world temperatures are likely torise by 2 degrees to 4.9 degrees Celsius this century comparedwith pre-industrial times.This could lead to dangerous weather patterns - includingmore frequent and powerful droughts, floods and storms -increasing the pressure on agriculture.Food production itself is a major contributor to climatechange.Agriculture, forestry and changes in land use togetherproduce nearly a quarter of global greenhouse gas emissions,making them the second largest emitter after the energy sector,said the United Nations Food and AgricultureOrganisation.The volume of food transported around the world also isexacerbating global warming.The global demand for food is expected to soar as theworld's population is projected to grow to 9.8 billion people by2050, up from 7.6 billion today, according to the U.N.Crops now take up 11 percent of the world's land surface,and livestock grazing covers 26 percent of ice-free land,according to the Organisation for Economic Co-operation andDevelopment (OECD).Farming accounts for about 70 percent of all water usedglobally, said the OECD.Water scarcity already affects more than 40 percent of theworld's population, according to the U.N.That number is expected to rise due to global warming, withone in four people projected to face chronic or recurringshortages by 2050, the U.N. said."Urgent action needs to be taken, including working tosupport the agriculture sector to increase its resilience toenvironmental changes," said Dangour. "And this must be apriority for governments across the world."(Reporting by Lin Taylor @linnytayls, Editing by Jared Ferrie;Please credit the Thomson Reuters Foundation, the charitable armof Thomson Reuters that covers humanitarian issues, conflicts,land and property rights, modern slavery and human trafficking,gender equality, climate change and resilience.
