Avocado Seed Skin

Avocados grown in California are threatened by drought, saltier soils, and even sunburn; some growers are choosing not to plant trees destined to mature (and struggle) in hotter conditions of the future. Grist quotes Jay Famiglietti, a senior water scientist at NASA’s Jet Propulsion Laboratory: “It’s a virtual certainty that California will get drier. I don’t think it’s a climate that’s conducive to orchard crops anymore.” One report estimates that avocado yields in California could decline 40% by 2050. Planting cover crops between rows of trees helps protect soil from erosion, and retain more water.
