Kolar, Karnataka | Solar Pumps Tool Made with Humane Club

Kolar, Karnataka

In the district, horticulture crops occupy a relatively high proportion of gross cropped area, raising the economic viability of solar pumps here. 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

Approaches Feasibility
Individually owned off-grid solar pumps Not Suitable
Solarisation of feeders Suitable
Solar based water as a service Limited SUitability
Promote 1 HP and sub-HP pumps Limited Suitability

Individually owned off-grid solar pumps

Not Suitable

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

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 3,890 30
Water Availability Index 0 0
Crop revenue per holding (INR) 11,043 10
Medium and long term institutional credit disbursed in a year (in INR Crore) 84.4 66

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 19% 67

Solar based water as a service

Limited SUitability

The district has a relatively high concentration of small and marginal farmers, and a rather high proportion of unirrigated area, but groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be considered while promoting solar-based water as a service, in order to improve the economic viability of the model, increase water availability, and decrease the effective cost of irrigation in the district.

Parameter Value Percentile
Water Availability Index 0 0
Proportion of small and marginal cultivators 88% 55
Unirrigated net sown area as a share of total net sown area 79% 69

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of gross cropped area under horticulture crops, a high concentration of marginal farmers and a comparatively high disbursement of institutional credit to marginal farmers, but groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be promoted to improve the viability of small capacity pumps.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 30% 91
Water Availability Index 0 0
Proportion of marginal cultivators 67% 54
Medium and long term institutional credit disbursed in a year (in INR Crore) 84.4 66

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 79% 69

Doubling Farmers’ Income – Capital Investment

Given the high concentration of small and marginal farmers, and their relatively better access to institutional credit, the district is suitable for doubling farmers’ income through capital investment. Solar pumps could be one of the farm technologies to invest in for farmers, especially 1 HP or sub-HP pumps for marginal farmers.

Parameter Value Percentile
Proportion of small and marginal cultivators 88% 55
Medium and long-term institutional credit disbursed in a year to small and marginal cultivators (in INR Crore) 84.4 66

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 79% 69

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 climate resilience score 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.

Parameter Value Percentile
Proportion of small and marginal cultivators 88% 55
Score on Climate Change Vulnerability Index 0.51 72

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 43% 79
