UMCSAWM ESD WI project carried out many watershed status evaluation projects as PBL projects. These works demonstrated that it is possible to quantify and rank sub watersheds on the level of importance with regards to the surface water resources. These quantifications done amidst data scarcities, demonstrates the possibility of a measure of water availability, water pollution status and alternative solutions that could be used for stakeholder discussions and taking effective steps for environmental sustainability. This method practiced and demonstrated by the UMCSAWM with case studies on watersheds with various development activities and a multitude of water users, is a quantified solution for Sustainable Water Resources Management. This method uses commonly available data, field visits, stakeholder consultations and rational engineering judgements to provide a critical analysis on a sub watershed basis. Once sub watershed status is identified, this method gives the discretion to commence better data collection in critical sub watersheds thereby making data collection programs cost effective.
Hence a policy decision needs to be taken to commence quantified situation analysis of water resources for all key watersheds and sub watersheds in order to arrive at suitable institutional arrangements and remedial measures for the sustainability of watersheds.
