Participatory Decision Making for Sanitation Improvements in Unplanned Urban Settlements in East Africa
Astrid Hendriksen, et al. Wageningen University, Wageningen, Netherlands
Solving the problem of inadequate access to sanitation in unplanned settlements in East Africa needs to combine social and technical dimensions in such a manner that they fit the local context. The modernized mixtures approach offers an analytical framework for identifying such solutions, but this approach requires effective methods for participatory decision making.
This article intends to contribute to filling this gap by identifying and further elaborating an appropriate multicriteria decision-making tool. The multicriteria decision analysis methodology, Proact 2.0, offers an adequate solution as it creates the possibility to connect knowledge, experiences, and preferences from scientists, experts, and policy makers with those of the end users.
We show in particular that users not always prefer the most optimal sanitation system, defined from an “expert” point of view. This article concludes that using Proact 2.0 can lead to substantial improvements in decision making in the field of sanitation in unplanned settlements in East Africa.
