This publication reviews the Pest Risk Identification SErvice (PRISE), its purpose, role within government systems, its impact and next steps.

The key messages include:

• PRISE is an early-warning information system that helps to reduce farmers’ crop losses by utilizing earth observation data to generate location-specific short text message (SMS) alerts on the optimal time to act against pests

• PRISE is embedded in government plant health and agricultural extension systems, with their dissemination platforms used to send farmers PRISE alerts and related agricultural advice

• PRISE has reached over 2 million farmers in Kenya, Ghana, Zambia and Malawi

• A 2024 study among tomato farmers in Kenya found the alerts to have increased yields by 16% and income by 10%

• PRISE helps to reduce pesticide use, with the same study in Kenya finding alerts reduced pesticide spraying by 11% and pesticide costs by 12%

• PRISE is highly scalable to additional countries and can deliver data and advice from field-level to a national scale
