Why do Cabo Verde’s islands have few permanent rivers and streams?

Cabo Verde’s islands have few permanent rivers and streams primarily due to the archipelago's climate, which is characterized by extreme aridity and unpredictable precipitation.12

The islands experience cyclical droughts and long periods with little to no rainfall, making consistent water flow impossible. When rain does occur, it often arrives as torrential downpours rather than steady, sustained moisture. These intense events frequently cause significant water erosion and flooding, which further hinders the development of stable watercourses.12

Additionally, the physical landscape contributes to the scarcity of permanent water. The islands' soils are generally shallow, coarse, and rocky, often lacking the humus necessary to retain water effectively. These geological conditions, combined with the severe, recurrent droughts that have historically impacted the region, prevent the formation of lasting river systems. Consequently, the country faces chronic water shortages and relies on alternative sources such as storage cisterns, deep wells, and desalinization facilities for its water supply.134
