Darrang, Assam | Solar Pumps Tool Made with Humane Club

Darrang, Assam

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 district has a relatively high proportion of small and marginal farmers.

Deployment Approaches

Approaches Feasibility
Individually owned off-grid solar pumps Limited Suitability
Solarisation of feeders 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. But, a comparatively low concentration of diesel pump users, low crop revenue per holding, and a relatively low disbursement of institutional credit make it very difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 9,424 40
Water Availability Index 1 100
Crop revenue per holding (INR) 54,660 37
Medium and long term institutional credit disbursed in a year (in INR Crore) 4 31

Solarisation of feeders

Limited Suitability

The district has a comparatively high extent of feeder segregation, and its DISCOM has a high bulk power purchase rate. But, a relatively low penetration of electric pumps means that solarisation of the feeders would not help in increasing the deployment of solar for irrigation.

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 0% 0

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 91% 64
Unirrigated net sown area as a share of total net sown area 96% 92

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 12% 65
Water Availability Index 1 100
Proportion of marginal cultivators 76% 69
Medium and long term institutional credit disbursed in a year (in INR Crore) 4 31

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 96% 92

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 96% 92

Sub-Mission on Agricultural Mechanisation – Farm Power Availability

There is a comparatively low level of farm mechanisation in the district and a relatively low proportion of electric pump users, indicating an opportunity to increase the exisiting level of mechanisation through solar based irrigation. Solar powered irrigation could be deployed under the Sub-Mission on Agricultural Mechanisation to improve farm power availability.

Parameter Value Percentile
Level of farm mechanisation (tractors, harvesters, threshers per ha) 0 0
Proportion of cultivators reporting use of electric pumps 0% 0

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 24% 52
