Pest Risk Information SErvice (PRISE) is a 5-year project funded by the UK Space Agency’s International Partnership Programme (IPP) currently being conducted in five Sub-Saharan African countries (Kenya, Ghana, Zambia and Malawi). This project predicts pest risk throughout the growing season so that effective management advice can be provided to a smallholder farmer in a timely manner, resulting in an improvement in yields. An example of this approach for Fall Armyworm, an invasive caterpillar/moth that devastates maize, uses land surface temperature data to drive a biological model that predicts the peaks in larval population, so that when a critical level is reached, actionable advice can be sent to farmers.
