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 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. 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

Approaches	Feasibility
Individually owned off-grid solar pumps	Limited Suitability
Solarisation of feeders	Suitable
Solar based water as a service	Limited Suitability
Promote 1 HP and sub-HP pumps	Limited Suitability

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.

Parameter	Value	Percentile
Number of cultivators reporting use of diesel pumps	10,760	43
Water Availability Index	1	100
Crop revenue per holding (INR)	18,776	9
Medium and long term institutional credit disbursed in a year (in INR Crore)	174.2	79

Solarisation of feeders

Suitable

Given the relatively high bullk power purchase rate 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.

Parameter	Value	Percentile
Power purchase rate for DISCOM (INR/kWh)	4.1	57
Extent of feeder segregation	58%	43
Proportion of cultivators reporting use of electric pumps	4%	38

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.

Parameter	Value	Percentile
Water Availability Index	1	100
Proportion of small and marginal cultivators	79%	37
Unirrigated net sown area as a share of total net sown area	88%	79

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.

Parameter	Value	Percentile
Area under horticulture crops as a share of gross cropped area	5%	47
Water Availability Index	1	100
Proportion of marginal cultivators	68%	56
Medium and long term institutional credit disbursed in a year (in INR Crore)	174.2	79

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.

Parameter	Value	Percentile
Unirrigated net sown area as a share of total net sown area	88%	79

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.

Parameter	Value	Percentile
Unirrigated net sown area as a share of total net sown area	88%	79

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	5%	47

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	0.02	25

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.
