Application of Geospatial technology in MGNREGS

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/Taluka Panchayat 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.

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.

A CASE STUDY

Study Area

Patan Dist.Sidhpur Taluka

230 57’26.17” N and 720 26’1.76” E to

230 55’1.45” N and 720 78’37.08” E.

Nagavasan Village (5H3B7d1b ) Sidhpur TalukaPatan Dist.Gujarat State

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 (Contd.)

o Use of Mobile based software for updating the

Geo-spatial database.

o Integrating with MGNREGA-MIS system.

o Summarised and specialized spatial reports

for different hierarchies

o Annual satellite images (CARTOSAT Imagery)

to assess the outcome.

o Monitoring System output will become input

best managed projects

Conclusion

Geographic Information system (GIS) has a

vital role as a Decision Support System.

Decentralization of MGNREGS activities

and creation & management of asset

inventory requires a proper scientific tool.

The scope of GIS as an Information System

acts as a solution for reliable, real-time

and authentic information.
