Hassan, Karnataka | Solar Pumps Tool Made with Humane Club

Hassan, Karnataka

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 high for the district, suggesting higher purchasing capacity of the farmers here. For average crop revenue per holding, the district appears among the top 25 percentile of districts, implying higher investment capacity of the farmers here. 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 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 Suitable
Solarisation of feeders Limited Suitability
Solar based water as a service Suitable
Promote 1 HP and sub-HP pumps Suitable
Solarisation of individual grid-connected pumps Limited suitability

Individually owned off-grid solar pumps

Suitable

Availability of groundwater within the safe limit, a comparatively high concentration of diesel pump users, a relatively high crop revenue per holding, and institutional credit disbursed in relatively large amounts in the district make it a suitable candidate for the promotion of solar-based irrigation through the private ownership of solar pumps. Private ownership provides easy and reliable access to irrigation for farmers.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 37,998 68
Water Availability Index 0.78 66
Crop revenue per holding (INR) 160,678 78
Medium and long term institutional credit disbursed in a year (in INR Crore) 71.2 63

Solarisation of feeders

Limited Suitability

The district has a relatively high penetration of electric pumps and a comparatively high extent of feeder segregation but its DISCOM incurs a relatively low cost for supplying power. As the power purchase rate of the DISCOM increases going forward, solarisation of the feeders may become economically viable in the district.

Parameter Value Percentile
Actual cost of power supply (INR/kWh) 5.53 31
Extent of feeder segregation 83% 58
Proportion of cultivators reporting use of electric pumps 6% 46

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 0.78 66
Proportion of small and marginal cultivators 89% 59
Unirrigated net sown area as a share of total net sown area 76% 66

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 38% 91
Water Availability Index 0.78 66
Proportion of marginal cultivators 66% 53
Medium and long term institutional credit disbursed in a year (in INR Crore) 71.2 63

Solarisation of individual grid-connected pumps

Limited suitability

The district has a relatively high penetration of electric pumps, ground water available within the safe limits and a comparatively high extent of feeder segregation. But the relatively low power subsidy for agriculural consumers make solarisation of individual grid-connected pumps an inefficient way of enhancing solar pumps in the district.

Parameter Value Percentile
Water Availability Index 0.78 66
Actual cost of power supply (INR/kWh) 5.53 31
Extent of feeder segregation 83% 58

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.

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 89% 59
Medium and long-term institutional credit disbursed in a year to small and marginal cultivators (in INR Crore) 71.2 63

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 76% 66

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 score on climate change vulnerability index 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 89% 59
Score on Climate Change Vulnerability Index 0.78 98

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
