4. The Approach
Creation, development and management of geo-spatial database depicting present conditions of land (terrain), water and vegetation with respect to watershed under different ownerships at village level
Compatible (village level), socio-economic aspects and their analysis.
Historical, land parcel-level / locale specific, earlier execution of works under various schemes including watershed programmes

5. The Approach Prioritization of watersheds Developmental Planning
Monitoring and Evaluation
Incorporating historical development works in Watershed area

21. GIS in Implementation
Using GIS Technology, the condition, limitation and potential of the land parcel is derived
Draft Action Plan is prepared on the basis of findings and prescriptions of Agricultural Universities/Research institutes
Draft Action Plan incorporates Ridge to valley approach
Final Action Plan is prepared based on PRA exercises at the village level

22. Horticulture Plantation Maintenance of Plantation

23. Integrated Monitoring & Evaluation System
Monitoring with the help of a web database
Timely updating the database through eGram by Village Watershed Committee
Analysis of the work in progress by PIA (and higher supervisory levels)
Specific and timely corrective measures
Summarised and specialized reports for different hierarchies
Evaluation & Feedback through mobile phone with the help of customized software will be attached to web based GIS

24. Impact Assessment & Feedback Mechanism
Annual satellite images to assess the impact
Output of the assessment will become input data for the next project.
Effective Planning
