Pest Risk Information Service (PRISE) An estimated 40% of the world’s crops are lost to pests (including insects, mites and plant pathogens), impacting on the ability of smallholder farmers to feed their families and also affecting international trade and food supply chains. By alerting them to the potential presence of pests, this project aims to enable farmers to manage outbreaks more effectively using Integrated Pest Management methods. These techniques have many advantages, such as the reduction of the use of inappropriate pesticides that lead to human and environmental benefits as well as reducing spend on unnecessary spraying. PRISE will use a range of satellite data at different scales to provide pest risk models with environmental information they need, of which surface temperature is the most important variable. Effective modelling on a country-wide scale requires data that accurately represents local weather conditions for agricultural zones. To meet these needs, data from satellite technology such as Meteosat SEVIRI, Terra/Aqua MODIS and Sentinel-3 SLSTR will be fused to produce a seamless service which will be used to drive pest risk models.
