Birbhum, West Bengal | Solar Pumps Tool Made with Humane Club

Birbhum, West Bengal

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 has a relatively high proportion of small and marginal farmers. 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
Solar based water as a service Limited Suitability
Promote 1 HP and sub-HP pumps Suitable

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 196,302 94
Water Availability Index 0.84 72
Crop revenue per holding (INR) 82,080 50
Medium and long term institutional credit disbursed in a year (in INR Crore) 21.9 47

Solar based water as a service

Limited Suitability

Groundwater availability in the district is within safe limit and the concentration of small and marginal farmers is comparatively high, but the proportion of unirrigated area is relatively low. A solar-based water service will have to compete with existing sources of irrigation.

Parameter Value Percentile
Water Availability Index 0.84 72
Proportion of small and marginal cultivators 91% 64
Unirrigated net sown area as a share of total net sown area 37% 32

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 14% 69
Water Availability Index 0.84 72
Proportion of marginal cultivators 73% 65
Medium and long term institutional credit disbursed in a year (in INR Crore) 21.9 47

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

Doubling Farmers’ Income – Capital Investment

Given the high concentration of small and marginal farmers, and their relatively better access to institutional credit, the district is suitable for doubling farmers’ income through capital investment. Solar pumps could be one of the farm technologies to invest in for farmers, especially 1 HP or sub-HP pumps for marginal farmers.

Proportion of small and marginal cultivators 91% 64
Medium and long-term institutional credit disbursed in a year to small and marginal cultivators (in INR Crore) 21.9 47
