16 Aug 2022 --- As Europe suffers the worst drought in over 500 years, North America suffers the worst dry period in over a millennia, with NASA images showing water reservoirs like Lake Mead at its lowest levels since its construction in the 1930s. Lack of water is constraining tomato production in a region that produces a quarter of the world’s output.The tomato crop in California is expected to be around 10.6 million metric tons, well under the peak reached in 2015 of 13.06 million metric tons, according to the US Department of Agriculture (USDA). Since the start of the year, California has cut its tomato estimates by 4.1%.
