Satellites can provide accurate land temperature information, which is one of the most important drivers of pest infestations. This, combined with weather data and computer models, can be used to give farmers enough time to spray pesticide and take other precautions.
Researchers from United Kingdom have developed an early warning system to prevent the crops of African farmers from being devastated.
The Pest Risk Information Service (Prise) combines temperature data and weather forecasts with computer models to output results.
It then sends farmers a mobile phone alert so that they can take precautions.
Prise is being used in Kenya, Ghana and Zambia and will be available in other parts of the world.
