This study assessed the impacts of flood on urban wetland ecosystem with emphasis on Nyabugogo wetland. The study was a descriptive with a quantitative and qualitative survey approach. Purposive sampling methods identified 100 respondents from Gatsata, Gisozi, Muhima and Kimisagara sectors of Kigali city which surround the wetland. The structured questionnaire was used to collect data which were analyzed by using Microsoft Excel. The results indicated that the majority of respondents consider wetland as the main source of provisioning services, subsistence and commercial crops, and livestock feed and fresh water. Respondents also agreed on the fact that regulating and support services are important services provided by the wetland. However, it was noticed that flood occurrence declines ecosystem services at the Nyabugogo wetland. Lack of protecting the wetland’s surrounding mountains from runoff and poor drainage systems were mentioned as key drivers to flood by 42% and 30% of respondents, respectively. Therefore, appropriate wetland protection measures are required to perform their functions and provide goods and services to sustain human life. This would lead to sustainable development and green growth resulting from the existing and delivery of ecosystem services.
