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

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

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

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

I. Fire Management: Fires in Indonesia

Presentation of the tool to CARE and Ministry of Environment (Indonesia). Improvement and publications are in progress
