Dhubri, Assam - Solar Pumps Tool | Solar Pumps Tool Made with Humane Club

Dhubri, Assam

In the district, a relatively large proportion of the net sown area is unirrigated, indicating high irrigation demand. In the district, horticulture crops occupy a relatively high proportion of gross cropped area, raising 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. There is a comparatively low level of farm mechanization, possibly due to low awareness or poor outlook towards progressive technologies amongst the farmers here. 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
Solarisation of feeders Suitable
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 high crop revenue per holding, but has a relatively low disbursement of institutional credit. Long-term bank loans should be promoted in the district to enable the adoption of capital-intensive farm technologies, including solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 86,990 85
Water Availability Index 1 100
Crop revenue per holding (INR) 95,520 56
Medium and long term institutional credit disbursed in a year (in INR Crore) 0 0

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) 4.45 90
Extent of feeder segregation 100% 69
Proportion of cultivators reporting use of electric pumps 8% 51

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.

Parameter Value Percentile
Water Availability Index 1 100
Proportion of small and marginal cultivators 87% 53
Unirrigated net sown area as a share of total net sown area 88% 79

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of horticulture crops under gross cropped area, high concentration of marginal farmers and groundwater availability within the safe limit, but disbursement of institutional credit to marginal farmers is comparatively low. Greater support, either through subsidies or credit, would be required to enable marginal farmers to adopt solar pumps.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 19% 76
Water Availability Index 1 100
Proportion of marginal cultivators 68% 56

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 88% 79

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 88% 79

Per Drop More Crop

In the district, crops suitable for drip and sprinkler irrigation occupy a relatively high proportion of gross cropped area, making it easy to adopt such high precision irrigation methods. Solar pumps, along with other efficient and precise water application devices, could be deployed under Per Drop More Crop to promote efficient irrigation.

Parameter Value Percentile
Area under crops suitable for drip and sprinkler irrigation as a share of total cropped area 30% 61
