Ratnagiri, Maharashtra

In the district, a relatively large proportion of the net sown area is unirrigated, indicating high irrigation demand. 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 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 ground water available within the safe limit and a relatively high disbursement of institutional credit. But, low crop revenue per holding, and a comparatively low concentration of diesel pump users make it difficult to promote the private ownership of solar pumps here.

Solarisation of feeders

Suitable

Given the relatively high cost of power supply for the respective DISCOM, a comparatively high extent of feeder segregation, and a high penetration of electric pumps, solarisation of the feeders would be a recommended way to promote solar-powered irrigation in the district. It would ensure the rapid and cost effective solarisation of irrigation power at a large scale.

Solar based water as a service

Limited Suitability

Groundwater availability is within the safe limit in this district and the proportion of unirrigated area is high. However, a comparatively low concentration of small and marginal farmers indicates low demand for water as a service.

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has groundwater availability within safe limit, a rather high concentration of marginal farmers, and a comparatively high disbursement of institutional credit to marginal farmers, but the proportion gross cropped area under horticulture crops is relatively low. Farmers should be incentivised to grow horticulture crops based on the agro-economic suitability of the region and market linkages to improve their revenue, making small sized pumps viable, by improving their capacity utilisation.

Solarisation of individual grid-connected pumps

Suitable

Given the relatively high rate of power subsidy for agriculture consumers, a comparatively high extent of feeder segregation, ground water available within the safe limits and a high penetration of electric pumps, solarisation of individual grid-connected pumps would be a recommended way to promote solar-powered irrigation in the district. It would ensure the rapid and cost effective solarisation of irrigation power at a large scale.

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.

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.

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.

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.
