If not destroyed early, Desert Locust can damage crops and cause famine across multiple countries Food Security: Desert Locust Management Monitoring vegetation in desert areas is required

I. Food Security: Application At the request of the UN FAO, a web-based tool was created to support Desert Locust management and control Eliminates NDVI-based error for identification of locust habitat Adds daily and 10-day CMORPH rainfall estimates for identification of potential breeding areas Michael Bell, Benno Blumenthal

In Feb 2007, vegetation was detected using IRI MODIS images. The information was used by the Ministry of Agriculture in Asmara to send control teams to the coastal area. Desert Locusts were found and control measures taken. I. Food Security: Application

In West Africa, the nomad population is at risk of contracting and transmitting water vector-borne diseases throughout the populations of Burkina Faso, Mali and Niger UN WHO requested a tool to monitor water bodies in this region UN WHO NOMADE project I. Human Health: Disease Transmission

IRI provides Short Wave Infrared composite images, enabling UN WHO to monitor and integrate water bodies into their Healthmapper GIS MODIS images at 250m spatial resolution composite I. Human Health: Disease Transmission

MODIS images: composite and NDVI are now available through IRI Health Maproom Ministry of Health in Eritrea follows NDVI indices on regular basis and provides warnings to the sub-districts I. Human Health: Application Michael Bell, Benno Blumenthal, John del Corral, Emily Grover-Kopec
