9 Why Plan at Micro watershed level 80% of the MGNREGS works are based onNatural 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 investmentEffective planning at Micro-watershed Level ( Ha.) would result in the creation of sustainable assets and concrete measurable outcomes at village level.

12 GIS based planning & monitoring for MGNREGS A CASE STUDY
13 Study Area Patan Dist. Sidhpur Taluka Nagavasan Village (5H3B7d1b ) 3/31/2017Study AreaPatan Dist.Sidhpur TalukaNagavasan Village(5H3B7d1b )Sidhpur TalukaPatan Dist.Gujarat State230 57’26.17” N and ’1.76” Eto230 55’1.45” N and ’37.08” E.Ictard.daiict.ac.in
14 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 productivityBiotic pressure on Gauchar and community land because of non-production of fodder on private land
16 Advantages of MappingMapping facilitates better understanding of activities both by the literate and illiterate (major beneficiaries).Mapping helps deriving a platform for coordination between MGNREGS and other line department for convergence.The maps (in digital form) can be easily shared between the line departments & other stakeholders which results in better fund flow and aids in monitoring and evaluation.

22 Measuring Soil Erodibility 3/31/2017Measuring Soil ErodibilityA sustainable model which decreases soil erosion, silting and degradation of present water harvesting structuresUse of Soil erosion equation for identifying various parameterUniversal Soil Loss Equation (USLE)Soil Loss = RKLSCPSoil erosion was estimated using Universal soil Loss Equation (USLE) (Wischemier, W.H and Smith, D.D, 1978).Ictard.daiict.ac.in
23 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.
