World’s vegetable supply to be reduced by one-third by 2050

Eating a healthy diet is likely to become more difficult in the future. Researchers are warning that climate change could cause the world’s supply of vegetables to fall by more than a third by 2050.Leafy greens, tomatoes, pulses and wheat are set to become more scarce unless urgent action is taken to tackle global warming, with a reduction of vegetables by 35% and legumes by 9% predicted.A study by the London School of Hygiene & Tropical Medicine revealed increased temperatures and water shortages would affect the production and nutritional quality of the crops.In warmer locations, such as Southern Europe and large parts of Africa and South Asia, the increased temperatures would cause a reduction in vegetable yields by an estimated 31%.Dr. Pauline Scheelbeek, the lead scientist on the study, which was published in the Proceedings of the National Academy of Sciences, said, “Our study shows that environmental changes such as increased temperature and water scarcity may pose a real threat to global agricultural production, with likely further impacts on food security and population health.“Vegetables and legumes are vital components of a healthy, balanced and sustainable diet and nutritional guidelines consistently advise people to incorporate more vegetables and legumes into their diet. “Our new analysis suggests, however, that this advice conflicts with the potential impacts of environmental changes that will decrease the availability of these important crops unless action is taken.”The research was based on a systematic review of the available evidence published since 1975 on the environmental impacts on crops, with experiments from 40 countries.Past research has shown that raised levels of carbon dioxide would increase crop yields, as well as new crop varieties and improvements in agriculture, which are urgently needed to protect vegetable supplies.
