Tampa, United States: Global warming is expected to make vegetables significantly scarcer around the world, unless new growing practices and resilient crop varieties are adopted, researchers warned on Monday.
By the end of this century, less water and hotter air will combine to cut average yields of vegetables -- which are crucial to a healthy diet -- by nearly one-third, said the report in the Proceedings of the National Academy of Sciences.
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 percent, said the report.
"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," said lead author Pauline Scheelbeek of the London School of Hygiene and Tropical Medicine.
Southern Europe, large parts of Africa and South Asia may be particularly affected.
The findings are based on a systematic review of 174 studies examining the impact of environmental exposures on yield and nutritional content of vegetables and legumes since 1975.
Some previous research has pointed to a likely increase in crop yields as carbon dioxide rises, but the current review found that any such boost would be cancelled out by higher greenhouse gases, reduced water availability for irrigation and rising temperatures.

my veggies are growing like a weed. What did I do wrong?
They’re trying to scare the vegetarians and vegans. That shouldn’t be too hard ;)
Oh no, no vegetables. When they do a ‘study’ on no fruits, then I’ll have to worry, but Citrus County used to be a citrus producing county, but in 1890s there was a hard freeze that kill the CITRUS INDUSTRY in Citrus County.
They publish something like this one week & by the next week,the price on veggies has increased at the grocery store. People on fixed incomes hit the hardest. That may or may not include women,minorities,& vegetarians.
