Tonk, Rajasthan | Solar Pumps Tool Made with Humane Club

Tonk, Rajasthan

Horticulture crops occupy a relatively low proportion of gross cropped area in the district, diminishing the economic viability of solar pumps 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 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 Limited Suitability
Solarisation of feeders Limited Suitability
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 comparatively high concentration of diesel pump users, high crop revenue per holding, and a relatively high disbursement of institutional credit. However, 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 solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 137,479 90
Water Availability Index 0.43 32
Crop revenue per holding (INR) 117,128 66
Medium and long term institutional credit disbursed in a year (in INR Crore) 899.6 97

Solarisation of feeders

Limited Suitability

The district has a relatively high penetration of electric pumps, and its DISCOM has a rather high bulk power purchase rate, but the district has a comparatively low extent of feeder segregation. Solarisation of the feeders will only be possible once the district separates agricultural feeders from the rest.

Parameter Value Percentile
Power purchase rate for DISCOM (INR/kWh) 4.07 48
Extent of feeder segregation 13% 30
Proportion of cultivators reporting use of electric pumps 35% 82

Solar based water as a service

Not Suitable

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

Parameter Value Percentile
Water Availability Index 0.43 32
Proportion of small and marginal cultivators 58% 11
Unirrigated net sown area as a share of total net sown area 41% 34

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 1% 12
Water Availability Index 0.43 32
Proportion of marginal cultivators 33% 16
Medium and long term institutional credit disbursed in a year (in INR Crore) 899.6 97

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

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 1% 12

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 42% 77
