E N D
Objectives • Use of GIS and RS for planning and monitoring of MGNREGS works for generation of social capital and employment. • Mapping the area and understanding the demographic profile, economic status of the stakeholders • Usage of the model as a platform for capacity building of the local community, Village/TalukaPanchayat and Project Implementing Agencies (PIA) . • Capturing the existing assets, current coverage of the area and generation of future action plan. • Use of various tools including RS Imagery for monitoring & evaluation.
Scope Mapping of the Project Area Development of Action Plan Monitoring and Evaluation Incorporation of asset inventory & socio-economic details

Tools to be used • Geographic Information System (GIS) • Global Positioning System (GPS) instruments • Remote Sensing (RS) Imagery • Management Information System (MIS) [NREGASoft] • Participatory Rural Appraisal(PRA) & Focus Group Discussions (FGD) • Social Audit
Availability of GIS Spatial Layers • Datasets Integrated in GIS • Different Types of Maps can be generated

Why Plan at Micro watershed level • 80% of the MGNREGS works are based on • Natural Resource Management (NRM), • Drought proofing, • Flood control & protection works, • Land development, • Micro & macro irrigation works, • Renovation of traditional water bodies (Desilting) • Absence of holistic & integrated approach leads to inadequate returns on investment • Effective planning at Micro-watershed Level (500-1000 Ha.) would result in the creation of sustainable assets and concrete measurable outcomes at village level.

GIS based planning & monitoring for MGNREGS A CASE STUDY
Study Area Patan Dist. Sidhpur Taluka Nagavasan Village (5H3B7d1b ) Sidhpur Taluka Patan Dist. Gujarat State 230 57’26.17” N and 720 26’1.76” E to 230 55’1.45” N and 720 78’37.08” E.
About Study area • Low rainfall area (700 mm) • Prone to excessive soil erosion due to ravines and sparse vegetative cover leads to inadequate recharge of ground water and siltation of water harvesting structures. • Low agriculture & milk productivity • Biotic pressure on Gauchar and community land because of non-production of fodder on private land
Action Plan Parameters • Socio-economic parameters • BPL population • SC/ST population • Small/Marginal farmers • Landless • Bio-Physical parameters • Ground water status • Vegetative cover status • Geomorphology of the area • Soil erodability status • Cropping pattern etc
Action Plan Parameters (Contd.) • Asset inventory • Existing water harvesting structures • Community land • Gauchar land • Land holdings by SC/ST • Land holdings by Marginal Farmers • Road connectivity • Gram Panchayat office • Irrigation structures (wells, field channels etc.) • Previous works under NREGS & other schemes
Measuring Soil Erodibility • A sustainable model which decreases soil erosion, silting and degradation of present water harvesting structures • Use of Soil erosion equation for identifying various parameter • Universal Soil Loss Equation (USLE) Soil Loss = RKLSCP Soil erosion was estimated using Universal soil Loss Equation (USLE) (Wischemier, W.H and Smith, D.D, 1978).
Measuring Soil Erodibility • ‘K’ is the erodibility factor - depends on soil characteristics (percent of sand, silt, organic matter content. K- Factor map for soil is prepared accordingly. • ‘LS’ is calculated from slope map - mainly dependent on percent slope and slope-length for each category of slope • ‘C’ factor is dependent on crop and the local vegetation. This is mapped from the land use and land cover map • ‘P’ factor is dependent on conservation practices applied or ought to be applied in watershed under NREGA.

Monitoring & Impact Assessment System • Creation of Web based GIS monitoring system at village level using e-Gram facilities with following database. • Type of assets • Use of GPS coordinates for asset created • Land parcel survey numbers. • The volume of work • Cost incurred. • Availability of Labour.
Monitoring & Impact Assessment System (Contd.) • Use of Mobile based software for updating the Geo-spatial database. • Integrating with MGNREGA-MIS system. • Summarised and specialized spatial reports for different hierarchies • Annual satellite images (CARTOSAT Imagery) to assess the outcome. • Monitoring System output will become input data for next annual action plan.
