A 12 Step Program to Stopping Drought and Desertification
Author: Green Prophet
Soaring temperatures and low precipitation could not occur at a worse time for many farmers in the United States, and around the world. Intensifying drought conditions are affecting corn and soybean crops throughout the Midwest, raising grain prices as well as concerns about future food prices.
The US Drought Monitor reports that 88 percent of this year’s corn crop and 77 percent of the soybean crop are now affected by the most severe drought since 1988. In response the Worldwatch Institute launched a 12 step guide to combatting drought and desertification. These tips can be used by policy makers around the world and in dry climates in the Middle East. Read on for the list.
1. Agroforestry: Planting trees in and around farms reduces soil erosion by providing a natural barrier against strong winds and rainfall. Tree roots also stabilize and nourish soils. The 1990 Farm Bill established the USDA National Agroforestry Center with the expressed aim of encouraging farmers to grow trees as windbreaks or as part of combined forage and livestock production, among other uses. See Green Prophet’s feature on the Nabateans to see how this idea can be applied in the Middle East.
2. Soil management: Alternating crop species allows soil periods of rest, restores nutrients, and also controls pests. Soil amendments, such as biochar, help soils retain moisture near the surface by providing a direct source of water and nutrients to plant roots, even in times of drought.
