Rohtas, Bihar - Solar Pumps Tool | Solar Pumps Tool

Rohtas, Bihar

Horticulture crops occupy a relatively low proportion of gross cropped area in the district, diminishing the economic viability of solar pumps here. 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. 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 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, 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.

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 96% 84
Unirrigated net sown area as a share of total net sown area 51% 42

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.

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 51% 42

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.

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 1% 16

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% 16
