For decades, Westlands has led the fight against environmental rules that restrict the flow of water from California's rivers to its farmers. It sued the government, lobbied friendly politicians, and took on critics wherever it found them, even in Congress. "Where's the outrage, that government decisions have created zero water supplies for communities in the San Joaquin Valley?" Westlands General Manager Tom Birmingham admonished a congressional committee in 2016. | |||

“Our great Farmers and people in the Hotel and Leisure business have been stating that our very aggressive policy on immigration is taking good, longtime workers away from them, with those jobs being almost impossible to replace,” Trump wrote. “This is not good. We must protect our Farmers. … Changes are coming!” | |||
===== Climate crisis could hit yields of key crops even if farmers adapt, study finds ===== | |||

Maize, soy, rice, wheat, cassava and sorghum yields are projected to fall by as much as 120 calories per person per day for every 1C the planet heats up, according to new research in Nature, with average daily losses that could add up to the equivalent of not having breakfast. | |||

The stark claim that the world has only 100; 60 or even 30 years of harvests left often hits the headlines. Although they continue to be repeated, there is no scientific basis to them. While the claims are overblown, soil erosion is an important problem. Erosion rates from across the world span five orders of magnitude. Some are eroding quickly: 16% of soils are estimated to have a lifespan of less than 100 years. Others are eroding slowly: half have a lifespan greater than 1000 years; and one-third have over 5000 years. To protect our soils we must adopt better agricultural practices – such as cover cropping, minimal or no tillage, and contour cultivation. This way we can extend the lifespan of the soils that we all depend on. | |||
