| Abstract: | This paper recognises the need for a revision of watershed development policy in India in relation to the planning of development
interventions involving agricultural intensification and rainwater harvesting and the need for new approaches to assist the
planning process. Building on, and using as an example, the results of biophysical and societal impact studies carried out
on two watershed development projects in Karnataka three new management/dissemination tools, are suggested. These are (1)
the web-based geographical information systems exploratory, climate land assessment and impact management tool dissemination
tool for disseminating to policymakers and non-specialist stakeholders the downstream impacts of watershed interventions,
(2) the ‘quadrant’ approach for ensuring that sustainability criteria are met and (3) Bayesian networks to investigate the
biophysical and societal impacts of interventions.
