Imagine discovering that within a few hours your entire crop for the season had been consumed by unwelcome visitors. In this edition of “Pounds of Prevention,” USAID examines the desert locust, a pest that affects the lives of millions of people in more than 65 countries throughout Africa, the Middle East, and Southwest Asia, an area that represents about 20 percent of the earth’s surface. The idea for this post came from CNN’s recent coverage of the Desert Locust Control Center in Mauritania that USAID supports through its agreement with the U.N. Food and Agriculture Organization (FAO). Mauritania is just one of several countries in West Africa, the Horn of Africa, and the Middle East to benefit from the FAO’s locust prevention system known as the EMPRES Program, to which USAID and other donors contribute.
