The frequency of droughts is likely to increase because of climate change, and this poses a huge threat to the available water resources, to livelihoods and to ecosystems. Routine drought monitoring is fundamental for developing an early warning system and an area-specific drought mitigation and adaptation framework. Surface waterbodies, especially those in arid and semi-arid environments, are vulnerable to the impacts of drought. The development of moderate-resolution sensors, such as the Landsat 8 Operational Land Imager (OLI) and the Sentinel-2 Multispectral Instrument (MSI), allow new opportunities to monitor droughts and their impact on surface waterbodies.enClimate changeDroughtEvapotranspirationSatellite dataSurface waterbodiesMultispectral remote sensing of the impacts of drought and climate variability on water resources in semi-arid regions of the Western Cape, South AfricaUniversity of Western Cape
