Using GIS and Remote Sensing to Access Water in the Drought-Prone Areas of Ethiopia and Madagascar

About

Remote sensing uses satellite technology to scan the earth and identify ‘high potential’ sites for the extraction of groundwater through the drilling of boreholes.In Ethiopia and Madagascar, UNICEF is combining these remote sensing techniques with hydrogeological, meteorological and geophysical data in order to develop groundwater suitability maps for drought-prone regions. Both initiatives are helping to significantly increase efficiency and cost effectiveness of borehole drilling, ultimately allowing UNICEF to reach more communities and strengthen climate change resilience.
