How can heavy rainfall damage land and dams in Cabo Verde?

In Cabo Verde, heavy rainfall often occurs as torrential downpours, which pose a significant threat to the landscape and infrastructure. Because the islands generally suffer from chronic water shortages and arid conditions, these sudden, intense bursts of precipitation cause severe damage through water erosion and flooding.1

The impact on the land and water management systems includes:

• Water Erosion: The islands' soils are typically shallow, coarse, and rocky, making them highly susceptible to being washed away during heavy rains. This intense erosion is a serious challenge that postcolonial governments have attempted to mitigate through reforestation, terracing, and the construction of dikes.12
• Destruction of Dams: The force of these torrential downpours can lead to the destruction of containment dams. While these structures are essential for improving water retention in the subsoil and supporting agriculture, they are vulnerable to the destructive power of sudden, high-volume water runoff.12

Efforts to combat these environmental challenges remain a priority to protect the limited land suitable for agriculture and to improve water conservation across the archipelago.2
