Within the Urban Water, Sanitation and Hygiene (WASH) sector, there is recognition that climate change is important and will affect the delivery of water and sanitation services. Similarly technical and professional staff within city and utility departments, who are responsible for the design, construction and maintenance of the physical systems that support this service delivery, are also already beginning to include climate considerations into their work, albeit at quite a simplistic level. HyCRISTAL’s work in Kisumu and Kampala therefore initially focused on trying to engage key people in the city to explore the situation with the current and likely future WASH system(s), considering it to be embedded within other city systems such as solid waste, drainage and infrastructure.
