Summary for Project title: R7779: Forecasting outbreaks of the brown locust in southern Africa.

Forecasters in southern Africa can now predict swarms of locusts cost-effectively and accurately. Plagues of the Brown Locust are extremely destructive in Botswana, Namibia and South Africa. They happen in at least seven out of ten years, often coinciding with droughts—a double whammy for poor farmers. Previously, warnings based on field surveys often came too late for farmers to take action. Forecasters in South Africa successfully used a new computer model—based on rainfall, vegetation, historical and satellite data—to show where locusts were likely to hatch out. They then warned farmers to prepare for outbreaks. Now, the governments of South Africa, Namibia and Botswana intend to use this system to strengthen control of locust and other migrating pests.
