Davanagere, Karnataka - Solar Pumps Tool | Solar Pumps Tool Made with Humane Club

Davanagere, Karnataka

Overall, the water availability for irrigation in the district (based on ground water development and long-term trends of water level decline) is critical since the resource is overexploited, jeopardizing the long-term sustainability of solar pumps. 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. 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 Not Suitable
Promote 1 HP and sub-HP pumps Not Suitable

Individually owned off-grid solar pumps

Limited Suitability

The district has a relatively high disbursement of institutional credit and high crop revenue per holding. However, ground water availability is below the safe limit, and concentration of diesel pump users is comparatively low, making it very difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 4,529 31
Water Availability Index 0.04 4
Crop revenue per holding (INR) 71,390 64
Medium and long term institutional credit disbursed in a year (in INR Crore) 235.2 85

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) 4.32 74
Extent of feeder segregation 94% 61
Proportion of cultivators reporting use of electric pumps 12% 58

Solar based water as a service

Not Suitable

The district has a relatively high proportion of unirrigated area. But, the concentration of small and marginal farmers is rather low and groundwater availability is below the safe limit, making it very difficult to promote solar-based irrigation through the water-as-a-service model here.

Parameter Value Percentile
Water Availability Index 0.04 4
Proportion of small and marginal cultivators 78% 36
Unirrigated net sown area as a share of total net sown area 60% 50

Promote 1 HP and sub-HP pumps

Not Suitable

The district has a comparatively high disbursement of institutional credit to marginal farmers. But, a rather low concentration of marginal farmers, a relatively low proportion of horticulture crops under gross cropped area, and groundwater availability below the safe limit make it extremely difficult to promote 1 HP and sub-HP pumps here.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 3% 40
Water Availability Index 0.04 4
Proportion of marginal cultivators 48% 30
Medium and long term institutional credit disbursed in a year (in INR Crore) 235.2 85

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 60% 50

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 60% 50

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 3% 40

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 26% 58
