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
Works carried under WDP, ARGW & Irri. Dept.

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
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
Documentation and development of
knowledge base
Research Protocol
Conclusion
Holistic approach to Natural Resource
Management
The significance of the new approach lies in
extending technology to enhance rural
livelihoods
Transparency and efficiency
Strengthening coordination among departments
Blending of traditional knowledge and scientific
process
Thanks….
