Structure leads to powerful applications
• The Data Library's open data model and ability to create networks of virtual web pages and resources leads to some powerful applications
• What follows is a brief explanation and some examples

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
![Page 19: IRI/LDEO Climate Data Library](https://reader033.vdocument.in/reader033/viewer/2022050719/56813e10550346895da7f03d/html5/thumbnails/19.jpg)
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.

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

IRI provides Short Wave Infrared composite images, enabling UN WHO
to monitor and integrate water bodies into their Healthmapper GIS

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

CARE Indonesia funded IRI to create Early Warning and Early Action Systems to manage Fires in peatland areas
Fires in Kalimantan release CO2 and smoke creating human health respiratory and air traffic problems
