Ramanagara, Karnataka - Solar Pumps Tool | Solar Pumps Tool

Ramanagara, 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. 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 has a relatively high proportion of small and marginal farmers.

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

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 304 15
Water Availability Index 0.13 13
Crop revenue per holding (INR) 10,559 9
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.8 38

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 8% 51

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 0.13 13
Proportion of small and marginal cultivators 92% 68
Unirrigated net sown area as a share of total net sown area 81% 71

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 11% 71
Water Availability Index 0.13 13
Proportion of marginal cultivators 77% 71
Medium and long term institutional credit disbursed in a year (in INR Crore) 9.8 38

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 81% 71

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 92% 68
Medium and long-term institutional credit disbursed in a year to small and marginal cultivators (in INR Crore) 9.8 38

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 81% 71

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 31% 64
