Sitamarhi, 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. 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

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

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.

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.

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.

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.

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 score on climate change vulnerability index 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.
