Comoros

Water resources Comoros has an annual rainfall of 900 mm (AMCOW 2018). The archipelago is made up of four islands and rainfall varies greatly, ranging from 2,000 to 4,000 mm/year depending on the altitude and orientation of the terrain (FAO 2016). Although 90 per cent of the population has access to safe drinking water, water security remains an issue. Groundwater and rainwater harvesting are major sources of water for the population on the main island of Grande Comore, while on the islands of Anjouan and Mohéli, the populations rely on surface water.
