Summary:
This report is a project assessment of the hazard exposure of populations in northern and southern Darfur. The results of this assessment will inform the International Organization for Migration (IOM)’s efforts to return and resettle internally displaced persons (IDP) throughout the country. Stable resettlement requires a resource-rich area with minimal hazards, such that communities may sustain rural livelihoods with minimal risk of evacuation. The selected regions are defined in 16 km square grids and subject to a framework developed by the Environmental and Livelihoods Vulnerability Mapping (ELVM) team. Terms such as “vulnerability”, “exposure”, “hazard”, “impact”, and “adaptive capacity” are explicitly defined within the context of the project. The project identifies four major environmental limiting factors that determine viability for livelihood—potential rain availability, rainfall predictability, potential groundwater availability, and potential energy (i.e. wood-fuel). These factors were assessed in combination to produce a multi-hazard vulnerability index (MHVI) for each 16km x 16km cell. This index was considered in the context of a community population and its adaptive capacity to attain an environmental and livelihoods vulnerability index (ELVI). The ELVI provides quantifiable expressions for the resettlement potential of each cell on the grid. These results are clearly displayed in maps and vulnerability diagrams. The vulnerability diagrams were produced using software especially created for the project. They depict each major environmental limiting factor plotted on radial axes. Vulnerability analyses are expressed in maps such that the most at-risk areas and their hazards are clearly seen. This report contains diagrams from select study areas, though diagrams for each cell are available on the project’s online platform. The report concludes with recommendations for further analyses that would broaden the geographical scope of the assessment to western Darfur. Quality will be enhanced during future stages through consultations with regional experts and related agencies. The additional information will enable the refinement of indices and provide current data that would improve future analyses. ( English )
