Tanzania – Ecorys / World Bank – Design Charrette for Msimbazi River

This project consists of 2 stakeholder workshops and 6 design charrettes which are held in a half a year’s time. The objective of the design charrettes is to develop, together with all stakeholders and communities, a strategic management framework for the entire catchment area of the Msimbazi River basin as well as a detailed plan for the lower part of the catchment. Charrettes (as means of participatory design process) are particularly suitable to address complex multi-facetted and interrelated social, technical and environmental issues. The Msimbazi River basin, covering a large part of Dar es Salaam’s urban area, is characterised by extreme high (informal) urbanisation rates, crossing of major infrastructures, a mosaic of different urban land uses and a whole range of environmental and sanitation issues. One of the main issues is the increasing severity and frequency of flash floods affecting the area.
