OAR@ICRISATMeasurable biophysical indicators for impact assessment: changes in water availability and quality.K LSahrawatauthorK VPadmajaauthorPPathakauthorS PWaniauthorThe impact of agricultural and natural resource management (NRM) practices on water quantity and quality are examined. The various biophysical indicators proposed to assess surface and groundwater quantity and quality impacts of agricultural and NRM interventions are discussed with examples drawn from recent literature and case studies from watersheds in the semiarid tropics. Future research needs for developing more effective and measurable indicators of water quantity and quality for the purpose of monitoring the biophysical impacts of technological and resource management interventions are highlighted.Watershed ManagementAgriculture-Farming, Production, Technology, Economics2005CAB International PublishingBook Section
