Description:
The Cooum River is an extremely polluted stream that flows through Chennai, India. Past attempts to rehabilitate the river have focussed on physical interventions such as dredging. However, the problem continues to worsen. This research has borrowed techniques from adaptive management and soft systems methodology to apply an ecosystem approach to the problem. This involved participatory development of conceptual models of relevant systems that informed construction of a GIS-based DSS and environmental model. This paper addresses the link between conceptual models and the DSS. The process of problem identification, system conceptualization, development of the GIS database and DSS, and its use for exploratory scenario analysis was found to stimulate learning about the situation and promoted novel solutions to the problem.
