"Africa’s cities, from large metropolises to smaller towns, are increasingly characterized by growing #UrbanSprawl. #Kinshasa, Democratic Republic of Congo, is expanding by about 2,000 people and 5 hectares (10 football fields) every day, according to a World Bank estimate. #Kumasi, an intermediary city in #Ghana, is growing more than 5% every year — at least twice as fast as the capital city, Accra.
As cities and surrounding farmlands expand further into their hinterlands, they encroach upon watersheds essential to water supply and climate resilience.
Watersheds are the natural area of land that drain into a common body of water. The consequences of their degradation are threefold. Without tree cover and healthy soils to absorb rainfall, cities may lose a critical source for groundwater recharge, leading to water shortages. Not only does the quantity of water suffer, so does its quality. Without strong roots to protect and anchor the soil, sediment and the chemicals within it are washed into nearby water bodies, often the primary source for a city’s drinking water. That same runoff can turn into floodwater.
How Natural Infrastructure Supports #WaterSecurity.
Many cities that once depended on their watersheds for water now face both increasing scarcity and heightened vulnerability to #extremeWeather. There are, however, #NatureBasedSolutions to help alleviate these problems.
Through a combination of upland foresting and urban greening, watershed restoration efforts are starting to deliver positive results in three African cities..."

3 African Cities Restore Nature to Revitalize Their Rivers
African cities are sprawling into their forested watersheds, harming their water supplies in the process. That's why Kigali, Rwanda; Dire Dawa, Ethiopia; and Johannesburg, South Africa are re-greening their landscapes.
