Alexandra Township, one of Johannesburg’s most densely populated areas, has long battled environmental challenges, exacerbated by rapid urbanisation and inadequate waste management.
The Jukskei River, which runs through the township, has been a focal point of concern due to its high pollution levels and the increasing threat of flooding. The overcrowded conditions, combined with poor infrastructure, have made Alexandra particularly vulnerable to climate-related risks.
Writing for the World Resources Institute, Amanda Gcanga, Nikara Mahadeo, Mulalo Mbedzi and Eden Takele looked into how the SUNCASA initiative - Scaling Urban Nature-based Solutions for Climate Adaptation in sub-Saharan Africa - has been working to restore the river and its surroundings.
This project, funded by Global Affairs Canada and led by the World Resources Institute (WRI) and the International Institute for Sustainable Development (IISD), focuses on reducing flood risks by reintroducing green spaces and rehabilitating riverbanks.
The involvement of local organisations, such as the Alexandra Water Warriors, has been vital.
"The situation calls for urgent, collective action to restore the environment and protect our community from these escalating dangers," said Semadi Manganye, co-founder of the Water Warriors.
His group has been instrumental in mobilising the community, advocating for better waste management, and working alongside SUNCASA’s implementing partners to clean up the Jukskei.
A site visit on August 22, led by Canadian Minister of Foreign Affairs Mélanie Joly, alongside Johannesburg officials, highlighted the importance of these nature-based solutions.
During the visit, Minister Joly praised the community's efforts, emphasising the need for continued cooperation between international donors and local stakeholders to ensure long-term sustainability.
One key aspect of the initiative is its focus on social equity, particularly for women and marginalised groups who are disproportionately affected by climate shocks. Through gender-responsive planning and local capacity-building, SUNCASA aims to ensure that these groups are central to decision-making processes.
Partner organisations, such as GenderCC, are working to strengthen community participation in climate governance, which is crucial for achieving sustainable outcomes.
SUNCASA’s efforts in Alexandra are just the beginning of a broader multi-year initiative, which also includes cities in Ethiopia and Rwanda. By integrating nature-based solutions into urban planning, the project aims to build more resilient communities across Africa.
