When the Operation Department of Emergency Preparedness (ODEP) of the United Nations World Food Programme (WFP) wanted to understand the higher vulnerabilities among populations living in areas prone to natural disasters as part of its work to mitigate disasters and coordinate response operations, it chose Esri ArcGIS software.

Today, the ODEP actively supports emergency relief efforts around the world with GIS analysis. This analysis considers factors such as environmental degradation, food insecurity, malnutrition, and the historical occurrences of natural disasters. Satellite images are analysed to identify poor growing seasons and years of low crop productions. The analyses help the WFP quickly develop intervention strategies when disaster strikes.
The World Food Programme (WFP) is the food assistance branch of the United Nations. Formally established in 1963, the WFP is the world’s largest humanitarian organisation fighting hunger worldwide. Its primary mission is providing food to those who are unable to obtain it for themselves. On an average, the WFP delivers food to more than 90 million people per year, 58 million of whom are children. In addition to food security, the WFP works to reduce child mortality, improve maternal health, and combat disease.
In addition to data acquired from the host country and the data it collects, the WFP obtains regular updates regarding seasonal food insecurity conditions throughout the world from the US Agency for International Development (USAID) Famine Early Warning Systems Network. USAID analyses the data it receives from US agencies, including the National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), United States Geological Survey (USGS), and the United States Department of Agriculture (USDA), to produce its reports and forecasts, which it then provides to the WFP and other relief agencies.
Managing the Disaster Cycle
The four recurrent steps in the disaster cycle are prevention, preparedness, response and recovery. Because it is cyclic, there is no actual beginning or end; however, GIS plays a strategic role throughout the entire cycle.
“GIS is used extensively in the prevention step of the disaster cycle,” says Andrea Amparore, GIS analyst, ODEP. “Prevention includes the evaluation of man-made features, such as dams and levees, to make sure they can withstand rising floodwater, as well as determining the structural integrity of buildings, the reseeding of hillsides after deforestation to reduce mudslides, the evaluation of building codes and land-use zones to make sure they meet current safety standards, instigating community awareness campaigns to help residents better prepare themselves in the event of a disaster, and so on. Using GIS throughout this step provides management tools for project planning, review, and implementation.”
Preparedness includes risk identification and assessment; the development and maintenance of emergency communication services; stockpiling essential food supplies, water, and medicine; and the establishment of evacuation routes. “GIS is used here in the evaluation and categorisation of potential risks, as well as determining the optimum locations for emergency food stockpiles, the development of evacuation plans, and determining the optimum routes for refugees if it becomes necessary for them to evacuate,” adds Amparore.
Response requires real-time monitoring for disaster relief efforts such as resource allocation, the status of transportation routes, and the relocation of civilian populations. GIS is used for forecasting the impact of imminent natural disasters, tracking human and livestock migration, monitoring the effectiveness of relief operations, and allocating resources.

The recovery step includes the provision of temporary relief, such as food and shelter for disaster victims, as well as damage assessment, repair, and reconstruction. “GIS is ideal for logistics management and is used to determine where resources are needed so that recovery efforts can be prioritised,” says Amparore. It is also used to specify where distribution stations should be positioned; evaluate the condition of existing humanitarian corridors; and establish the location of refugee camps, emergency supply depots, and relief worker staging areas.
The Future of GIS at the WFP
Because GIS is used throughout the WFP, the organisation decided to implement an enterprise system based on ArcGIS for server technology to better organise and manage its expanding geospatial databases. This has stimulated new projects in the agency and an evaluation by the WFP of how GIS can be better used by its departments and partners.
For example, the WFP’s Vulnerability Analysis and Mapping unit recently created the Spatial Information Environment in an effort to increase access to original and derived spatial information within the WFP and its partners. In addition, it is working with FAO to develop an ISO-standard metadata clearinghouse to enable greater compatibility and promote the sharing of spatial data between agencies.
“Standardisation is the key to the continued growth of GIS at the WFP,” concludes Amparore. “This will allow us to expand our analytical capabilities and adopt an even greater scientific approach to data analysis. I also think the involvement of local universities, when possible, would help facilitate our work and provide the host country with a greater sense of involvement in our relief efforts.”
