The southeastern part of the African continent is highly vulnerable to transboundary extreme climate-related events, in particular floods, droughts and cyclones. It is also part of one of the world’s fastest urbanizing regions, Sub-Saharan Africa, where the total share of urban population is projected to increase to 60 per cent by 2050 from the current 40 per cent. This trend is driven by increasing rural-urban migration combined with the sustained rapid population growth rate in the region. This project focused on strengthening capacities and establishing conditions of four South-East African countries to build resilience and adapt to the adverse effects of climate change in vulnerable cities and towns. The project supported and worked closely with local and national governments in these four countries to reinforce their capacity and knowledge of disaster risk management and urban climate resilience, as well as the development of policies, urbans plans, knowledge exchange activities and resource mobilization for urban risk reduction and resilience initiatives. Through these activities, the project was able to strengthen multilevel governance relations between local and national governments and build trust and community ownership. The activities carried out through the project led to significant financing opportunities to scale-up the urban resilience portfolio of UN-Habitat in Africa. Most notably, the project established the evidence base needed for the formulation and development of the $14 million Building Urban Climate Resilience in South-Eastern Africa project, the largest on-going project of the Agency. The development and successful financing of this project stems directly from the activities executed with the support of the Development Account. Overall, the Development Account project unlocked roughly $15 million in additional funding for further urban resilience building interventions in the four project countries.
