Using cloud computing techniques to monitor long-term variations in ecohydrological dynamics of small seasonally-flooded wetlands in semi-arid South Africa

•Semi-arid Southern African wetlands are lost due to unsustainable use and poor management.•Ramsar Convention on wetlands encourages development of frameworks for wetlands conservation.•The implementation of these frameworks is hindered by a dearth of high-resolution data.•Google Earth Engine (GEE) offers opportunities to address data challenges.•Findings underscores the relevance of GEE in evaluating wetland ecohydrological dynamics.
