Sanitation challenge in Wageningen

May 2008 | The Netherlands

The conference was deliberately aimed to create a dialogue between civil, process, agricultural and environmental engineers; urban planners, sociologists, economists, and political scientists who are involved in international sanitation research and implementation. It took place in Wageningen, the Netherlands from 19. to 21. May 2008.

Furthermore, this conference tried to bridge the gap between sanitation research and demonstration in the ‘North’ and in the ‘South’. Among others, the conference wanted to be a platform to present the findings of the ‘Decentralized Sanitation and Reuse’ (DESAR) project  performed in the Netherlands from 2001-2007, financed by EET  and STOWA and those of a sanitation and urban infrastructure research project in East Africa (PROVIDE).
