Land Susceptibility to Wind Erosion (LaSWE)
The Regional Centre for Mapping of Resource for Development (RCMRD), under the Global Monitoring for Environment and Security & Africa (GMES & Africa) project, with patnership with LocateIT Limited Company, implemented Earth Observation based System for Land Susceptibility to Wind Erosion (LaSWE). The application’s main aim was to use Earth Observation methods/algorithms and tools to generate geospatial data products for Wind Erosion Modelling.
The overall LaSWE goal aligns with GMES & Africa thematic chapters identified and agreed on for the Action Plan, which includes:
Long term Management of Natural Resources;
Water Resource Management;
Marine & Coastal Areas Management;
Food Security and Rural Development;
Climate Variability and Change;
Disaster Risk Reduction;
Health;
Conflict and Political Crisis, and
Infrastructure and Territorial Development.
Thus, LaSWE implementation ensures an evidenced based information, that will support the end users and stakeholders towards monitoring and assessing wind erosion impacts in the Eastern Africa Region, in order to achieve sustainable enviromental management.
