Participatoryground Water

Management

The objective is to equipgroundwater farmer/ users/stakeholders with the necessarydata, skills andknowledge to manage groundwater resources availableto them in a sustainable manner, mainly throughmanaging and monitoring their owndemand.

The assumptionis that access to scientificdata andknowledge will enable farmers to make appropriatechoices anddecisions regarding the use of

groundwater resources and agricultural practices.

Way Forward

Understanding of aquifer systems Arresting declining Ground Water Levels. Awareness generation for understanding the ground

water occurrence and recharge concepts.

Ground water management measures such asrecharge , conservation and recycle / reuse ofgroundwater.

Specific recharge plans for urban and rural areas Ground Water Regulation self regulation

Adoption of Participatory ground water managementapproach.
