Nagaon, Assam | Solar Pumps Tool Made with Humane Club

Nagaon, 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. 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 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 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 33,171 65
Water Availability Index 1 100
Crop revenue per holding (INR) 74,681 47
Medium and long term institutional credit disbursed in a year (in INR Crore) 28.3 50

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 5% 43

Solar based water as a service

Limited Suitability

Groundwater availability is within the safe limit in this district and the proportion of unirrigated area is high. However, a comparatively low concentration of small and marginal farmers indicates low demand for water as a service.

Parameter Value Percentile
Water Availability Index 1 100
Proportion of small and marginal cultivators 85% 48
Unirrigated net sown area as a share of total net sown area 93% 86

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 16% 73
Water Availability Index 1 100
Proportion of marginal cultivators 71% 62
Medium and long term institutional credit disbursed in a year (in INR Crore) 28.3 50

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 93% 86

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 93% 86

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) 0.03 15
Proportion of cultivators reporting use of electric pumps 5% 43

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% 51
