Ranchi, Jharkhand | Solar Pumps Tool Made with Humane Club

Ranchi, 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. The average monthly per capita expenditure of rural agricultural households is relatively low for the district, suggesting poor purchasing capacity of the farmers here. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers.

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 comparatively high concentration of diesel pump users. However, low crop revenue per holding, and the relatively low disbursement of institutional credit would make it difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 66,652 81
Water Availability Index 0.86 86
Crop revenue per holding (INR) 3,061 3
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.8 37

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) 4.31 70
Extent of feeder segregation 61% 51
Proportion of cultivators reporting use of electric pumps 1% 21

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 0.86 86
Proportion of small and marginal cultivators 79% 37
Unirrigated net sown area as a share of total net sown area 89% 81

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has groundwater availability within safe limit and a relatively high proportion of horticulture crops under gross cropped area. But, a rather low concentration of marginal farmers, and a comparatively low disbursement of institutional credit to them make it difficult to promote 1 HP and sub-HP pumps here.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 12% 72
Water Availability Index 0.86 86
Proportion of marginal cultivators 53% 36
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.8 37

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 89% 81

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 89% 81

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 1% 9
