Fluid African Cities- Bottom-Up Adaptive Decision-Support for Resilient Urban Water Security. A case study of the application of decision-scaling for the city-centric water system of Lusaka,Zambia within the Kafue Flats sub-basin

Globally, the implications of climate change and rapid urbanisation are a growing concern for the future of water resource management. African cities are places with significant water security risk, rapid urbanisation and multiple spatial and temporal scales (UN-WWAP, 2009). Identifying these risks provides insights into where resilience is required, which allows for informed adaptation decisions. Water managers are accustomed to changing circumstances and adapting to them; however, uncertainties associated with climate and socio-economic changes create an additional layer of complexity. Decision-support tools used for the evaluation and management of water resources should reflect the potential impacts of these changes.
