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

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
