Purbi Singhbhum, Jharkhand - Solar Pumps Tool | Solar Pumps Tool

Purbi Singhbhum, Jharkhand

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. 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 are (very) highly vulnerable 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 Limited Suitability
Solar based water as a service Suitable
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. But, a comparatively low concentration of diesel pump users, low crop revenue per holding, and a relatively low disbursement of institutional credit make it very difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 3,581 29
Water Availability Index 0.89 89
Crop revenue per holding (INR) 275 1
Medium and long term institutional credit disbursed in a year (in INR Crore) 0 0

Solarisation of feeders

Limited Suitability

The district has a comparatively high extent of feeder segregation, and its DISCOM has a high bulk power purchase rate. But, a relatively low penetration of electric pumps means that solarisation of the feeders would not help in increasing the deployment of solar for irrigation.

Parameter Value Percentile
Power purchase rate for DISCOM (INR/kWh) 4.31 70
Extent of feeder segregation 61% 51
Proportion of cultivators reporting use of electric pumps 0% 0

Solar based water as a service

Suitable

Availability of groundwater within the safe limit, a relatively high proportion of unirrigated area, and a rather high concentration of small and marginal farmers in the district make the water-as-a-service model a potential way to promote solar-based irrigation. The model could help in improving irrigation equity, without requiring a farmer to bear an upfront cost to purchase a pump.

Parameter Value Percentile
Water Availability Index 0.89 89
Proportion of small and marginal cultivators 88% 55
Unirrigated net sown area as a share of total net sown area 95% 90

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of horticulture crops under gross cropped area, high concentration of marginal farmers and groundwater availability within the safe limit, but disbursement of institutional credit to marginal farmers is comparatively low. Greater support, either through subsidies or credit, would be required to enable marginal farmers to adopt solar pumps.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 8% 63
Water Availability Index 0.89 89
Proportion of marginal cultivators 75% 67
Medium and long term institutional credit disbursed in a year (in INR Crore) 0 0

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 95% 90

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 95% 90

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% 0

Climate Resilient Farming for Small Farms

Given the high concentration of small and marginal farmers—the most vulnerable group to climate change—and a high climate resilience score provided by CRIDA*, the district is suitable for promoting climate resilient farming for small-sized farms. Solar pumps would assist in the same through low-carbon agriculture.

Parameter Value Percentile
Proportion of small and marginal cultivators 88% 55
Score on Climate Change Vulnerability Index 0.47 62
