It has a relatively small proportion of its net sown area unirrigated, indicating poor irrigation demand. 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. The number of medium and long-term institutional loans disbursed in the district is comparatively large, suggesting the availability of credit amongst farmers for potential investments. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers. The district has a relatively high proportion of small and marginal farmers. The district appears in the group of districts, which show (very) low vulnerability 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 a comparatively high extent of feeder segregation but its DISCOM incurs a relatively low cost for supplying power. As the power purchase rate of the DISCOM increases going forward, solarisation of the feeders may become economically viable in the district.

Solar based water as a service

Not Suitable

The concentration of small and marginal farmers is rather high in the district, but groundwater availability is below the safe limit. In addition, a relatively low proportion of unirrigated area makes it very difficult to promote solar-based irrigation through the water-as-a-service model here, unless it undercuts the price of water from existing sources, and improves water utilisation through promotion of micro-irrigation.

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of gross cropped area under horticulture crops, a high concentration of marginal farmers and a comparatively high disbursement of institutional credit to marginal farmers, but 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 small capacity pumps.

Solarisation of individual grid-connected pumps

Not suitable

The district has a relatively high penetration of electric pumps, ground water available within the safe limits and a comparatively high extent of feeder segregation but agriculture power subsidy is not very significant. Further with the groundwater availability below the safe limits, solarisation of individual grid-connected pumps may not be the right approach for the district

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 – Capital Investment

Given the high concentration of small and marginal farmers, and their relatively better access to institutional credit, the district is suitable for doubling farmers’ income through capital investment. Solar pumps could be one of the farm technologies to invest in for farmers, especially 1 HP or sub-HP pumps for marginal farmers.

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.

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.
