Rajsamand, Rajasthan | Solar Pumps Tool Made with Humane Club

Rajsamand, Rajasthan

Horticulture crops occupy a relatively low proportion of gross cropped area in the district, diminishing the economic viability of solar pumps here. Overall, the water availability for irrigation in the district (based on ground water development and long-term trends of water level decline) is critical since the resource is overexploited, jeopardizing the long-term sustainability of solar pumps. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers. The district appears in the group of districts, which are (very) highly vulnerable towards climate change, as per an index constructed by CRIDA.

Deployment Approaches

Approaches Feasibility
Individually owned off-grid solar pumps Limited Suitability
Solarisation of feeders Limited Suitability
Solar based water as a service Not Suitable
Promote 1 HP and sub-HP pumps Limited Suitability
Solarisation of individual grid-connected pumps Limited suitability

Individually owned off-grid solar pumps

Limited Suitability

The district has a comparatively high concentration of diesel pump users, high crop revenue per holding, and a relatively high disbursement of institutional credit. However, groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be promoted to improve the viability of solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 49,578 75
Water Availability Index 0.22 17
Crop revenue per holding (INR) 86,298 52
Medium and long term institutional credit disbursed in a year (in INR Crore) 36.8 54

Solarisation of feeders

Limited Suitability

The district has a relatively high penetration of electric pumps, and its DISCOM incurs a high cost for supplying power, but the district has a comparatively low extent of feeder segregation. Solarisation of the feeders will only be possible once the district separates agricultural feeders from the rest.

Parameter Value Percentile
Actual cost of power supply (INR/kWh) 7.1 95
Extent of feeder segregation 19% 33
Proportion of cultivators reporting use of electric pumps 26% 75

Solar based water as a service

Not Suitable

The district has a relatively high proportion of unirrigated area. But, the concentration of small and marginal farmers is rather low and groundwater availability is below the safe limit, making it very difficult to promote solar-based irrigation through the water-as-a-service model here.

Parameter Value Percentile
Water Availability Index 0.22 17
Proportion of small and marginal cultivators 81% 40
Unirrigated net sown area as a share of total net sown area 52% 44

Promote 1 HP and sub-HP pumps

Limited Suitability

The concentration of marginal farmers in the district is rather high and the disbursement of institutional credit to marginal farmers is also comparatively high. But, groundwater availability is below the safe limit and proportion of gross cropped area under horticulture is relatively low, making viability of small pumps difficult. Such pumps can be promoted in suitable areas of the district along with promotion of micro-irrigation as well as horticultural crops.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 2% 27
Water Availability Index 0.22 17
Proportion of marginal cultivators 59% 43
Medium and long term institutional credit disbursed in a year (in INR Crore) 36.8 54

Solarisation of individual grid-connected pumps

Limited suitability

The district has a relatively high penetration of electric pumps and power supply to its agriculture consumers is heavily subsidised. But the district has a comparatively low extent of feeder segregation and its groundwater availability is below the safe limits. Solarisation of individual grid-connected pumps will only be possible once the district separates agricultural feeders from the rest. Further the approach should be taken up with extreme caution as it may aggrevate the groundwater depletion.

Parameter Value Percentile
Water Availability Index 0.22 17
Actual cost of power supply (INR/kWh) 7.1 95
Extent of feeder segregation 19% 33

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

Har Khet ko Pani

A relatively high proportion of the net sown area in the district is unirrigated, indicating high irrigation demand. Solar pumps can help improve access to underground irrigation as part of Har Khet ko Pani.

Unirrigated net sown area as a share of total net sown area 52% 44

Doubling Farmers’ Income – Crop Intensity

A relatively high proportion of the district’s net sown area is unirrigated. Lack of access to irrigation is one of the major barriers to growing crops beyond two conventional seasons, rabi and kharif. Ensuring irrigation access through solar power will help improve cropping intensity and move towards the aim of doubling farmers’ income by 2022.

Unirrigated net sown area as a share of total net sown area 52% 44

Doubling Farmers’ Income – Crop Diversification

In the district, horticulture crops occupy a relatively low proportion of gross cropped area, indicating an opportunity for growing more high value non-staple crops. Solar-powered irrigation could be an alternative source of reliable irrigation, making it easier to achieve crop diversification and enhance farmers’ incomes.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 2% 27

National Mission on Oilseeds and Oil Palm (NMOOP)

The relatively low share of oilseeds and oil palm crops under gross sown area in the district makes it a suitable candidate for promoting NMOOP. Solar pumps could meet irrigation needs for these crops and help farmers diversify their yields beyond cereals.

Parameter Value Percentile
Area under oilseeds as a share of total cropped area 39
