Porbandar, Gujarat

Overall, water availability for irrigation in the district (based on ground water development and long-term trends of water level decline) is within the safe limit, enhancing long-term sustainability of solar pumps. 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 ground water available within the safe limit, a comparatively high concentration of diesel pump users, and high crop revenue per holding, but has a relatively low disbursement of institutional credit. Long-term bank loans should be promoted in the district to enable the adoption of capital-intensive farm technologies, including 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

Limited Suitability

Groundwater availability in the district is within the safe limit. But, a rather low concentration of small and marginal farmers and a relatively low proportion of unirrigated area make it difficult to promote solar-based irrigation through the water-as-a-service model here.

Promote 1 HP and sub-HP pumps

Limited Suitability

Groundwater availability in the district is within the safe limit. But, a rather low concentration of marginal farmers, a comparatively low disbursement of institutional credit to them and a relatively low proportion of horticulture crops under gross cropped area limit the demand for 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, ground water available within the safe limits and a comparatively high extent of feeder segregation. But the relatively low power subsidy for agriculural consumers make solarisation of individual grid-connected pumps an inefficient way of enhancing solar pumps in 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 – 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.
