​In African cities, nature-based solutions are being implemented to restore rivers, mitigate flood risks, and enhance climate resilience. These strategies not only address environmental challenges but also offer socio-economic benefits to local communities.​Wikipedia

Restoring Johannesburg’s jukskei river

In Johannesburg, South Africa, the Scaling Urban Nature-based Solutions for Climate Adaptation in Sub-Saharan Africa (SUNCASA) initiative is revitalizing the Jukskei River catchment. By removing invasive species and planting indigenous trees like wild olives and tree wisteria, the project aims to control flash floods, improve soil health, and enhance water quality. Local communities actively participate by planting trees and repurposing waste materials into art installations, fostering environmental stewardship and creating green spaces. ​

Integrating wetlands in beira’s flood management

The coastal city of Beira, Mozambique, faces significant flood risks due to its location at the mouth of a major river system. The Cities and Climate Change Project (3CP) integrated wetland restoration with engineered drainage systems along the Chiveve River. This approach enhanced biodiversity, improved erosion control, and provided a 17-hectare multi-use urban green park for residents. The project has protected over 50,000 people from recurrent flooding, created over 1,200 jobs, and improved public health by increasing access to green spaces. ​

Community-led restoration in dire dawa

In Dire Dawa, Ethiopia, SUNCASA focuses on restoring the Dechatu River catchment to address flood risk, erosion, and urban water stress. The initiative engages local communities in planting indigenous trees and implementing sustainable land management practices. These efforts aim to reduce the vulnerability of over 200,000 residents to climate-related disasters and enhance water security in the region. ​

Enhancing urban resilience in kigali

Kigali, Rwanda, is implementing nature-based solutions to restore critical upstream micro-catchments in the Nyabarongo River watershed. These efforts aim to reduce flood risks, prevent landslides, and combat soil erosion. By enhancing the resilience of approximately 975,000 people, the project contributes to sustainable urban development and climate adaptation. ​

These examples demonstrate the potential of nature-based solutions in African cities to address environmental challenges, improve livelihoods, and build climate resilience.
