Banka, Bihar | Solar Pumps Tool Made with Humane Club

Banka, Bihar

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 average monthly per capita expenditure of rural agricultural households is relatively low for the district, suggesting poor purchasing capacity of the farmers here. It has a relatively low penetration of banks in rural and semi-rural areas, impeding access to institutional credit for farmers. 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.

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 Suitable
Solarisation of individual grid-connected pumps Not suitable

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 a relatively high disbursement of institutional credit, but low crop revenue per holding. Greater support, either through subsidies or credit, would be required to enable farmers to adopt solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 243,691 96
Water Availability Index 1 100
Crop revenue per holding (INR) 15,457 7
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.7 37

Solarisation of feeders

Limited Suitability

The cost of power supply for the respective DISCOM in the district is rather high. But, a relatively low extent of feeder segregation and a comparatively low penetration of electric pumps make it very difficult and less effective to solarise the feeders here.

Parameter Value Percentile
Actual cost of power supply (INR/kWh) 5.84 38
Extent of feeder segregation
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.

Water Availability Index 1 100
Proportion of small and marginal cultivators 98% 93
Unirrigated net sown area as a share of total net sown area 29% 28

Promote 1 HP and sub-HP pumps

Suitable

1 HP and sub-HP pumps could help marginal farmers meet their needs in this district. A relatively high proportion of horticulture crops under gross cropped area, a rather high concentration of marginal farmers, a comparatively high disbursement of institutional credit to marginal farmers, and the availability of groundwater within the safe limit would drive the success of such small-sized pumps in the district. Such small pumps could also be put to use for lift irrigation, provided there is access to surface water.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 7% 57
Water Availability Index 1 100
Proportion of marginal cultivators 93% 95
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.7 37

Solarisation of individual grid-connected pumps

Not suitable

The power supply fto agricultural consumers in the district is heavily subsidised and the groundwater availiability is within the safe limits. But, a relatively low extent of feeder segregation and a comparatively low penetration of electric pumps make it very difficult and less effective to solarise the individual grid-connected pumps here.

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.

Unirrigated net sown area as a share of total net sown area 29% 28

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.

Unirrigated net sown area as a share of total net sown area 29% 28

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 11
