Kanniyakumari, Tamil Nadu | Solar Pumps Tool Made with Humane Club

Kanniyakumari, Tamil Nadu

It has a relatively small proportion of its net sown area unirrigated, indicating poor 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. The district has a relatively high proportion of small and marginal farmers. 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 Limited Suitability
Solar based water as a service Limited Suitability
Promote 1 HP and sub-HP pumps Limited Suitability

Individually owned off-grid solar pumps

Limited Suitability

The district has ground water available within the safe limit. But, a comparatively low concentration of diesel pump users, low crop revenue per holding, and a relatively low disbursement of institutional credit make it very difficult to promote the private ownership of solar pumps here.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 1,824 23
Water Availability Index 0.97 96
Crop revenue per holding (INR) 21,479 12
Medium and long term institutional credit disbursed in a year (in INR Crore) 22.2 47

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) 3.68 26
Extent of feeder segregation 0% 0
Proportion of cultivators reporting use of electric pumps 26% 75

Solar based water as a service

Limited Suitability

Groundwater availability in the district is within safe limit and the concentration of small and marginal farmers is comparatively high, but the proportion of unirrigated area is relatively low. A solar-based water service will have to compete with existing sources of irrigation.

Parameter Value Percentile
Water Availability Index 0.97 96
Proportion of small and marginal cultivators 99% 96
Unirrigated net sown area as a share of total net sown area 19% 21

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of horticulture crops under gross cropped area, high concentration of marginal farmers and groundwater availability within the safe limit, but disbursement of institutional credit to marginal farmers is comparatively low. Greater support, either through subsidies or credit, would be required to enable marginal farmers to adopt solar pumps.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 46% 94
Water Availability Index 0.97 96
Proportion of marginal cultivators 98% 99
Medium and long term institutional credit disbursed in a year (in INR Crore) 22.2 47

Leveraging Solar Pumps to Promote Policy Objectives

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

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 82% 97
