Sawai Madhopur, Rajasthan

It has a relatively small proportion of its net sown area unirrigated, indicating poor irrigation demand. 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

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.

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.

Solar based water as a service

Not Suitable

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

Promote 1 HP and sub-HP pumps

Not Suitable

The district has a comparatively high disbursement of institutional credit to marginal farmers. But, a rather low concentration of marginal farmers, a relatively low proportion of horticulture crops under gross cropped area, and groundwater availability below the safe limit make it extremely difficult to promote 1 HP and sub-HP pumps here.

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.

Leveraging Solar Pumps to Promote Policy Objectives

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

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.

Per Drop More Crop

In the district, crops suitable for drip and sprinkler irrigation occupy a relatively high proportion of gross cropped area, making it easy to adopt such high precision irrigation methods. Solar pumps, along with other efficient and precise water application devices, could be deployed under Per Drop More Crop to promote efficient irrigation.
