Thiruvarur, Tamil Nadu - Solar Pumps Tool | Solar Pumps Tool

Thiruvarur, Tamil Nadu

It has a relatively small proportion of its net sown area unirrigated, indicating poor irrigation demand. 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 penetration of banks in rural and semi-rural areas, facilitating higher access to institutional credit for farmers. 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 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

Not Suitable

The district has high crop revenue per holding overall. But, ground water availability is below the safe limit, the concentration of diesel pump users is comparatively low, and disbursement of institutional credit is also relatively 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 14,432 47
Water Availability Index 0.55 41
Crop revenue per holding (INR) 106,566 60
Medium and long term institutional credit disbursed in a year (in INR Crore) 0 0

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 33% 80

Solar based water as a service

Not Suitable

The concentration of small and marginal farmers is rather high in the district, but groundwater availability is below the safe limit. In addition, a relatively low proportion of unirrigated area makes it very difficult to promote solar-based irrigation through the water-as-a-service model here, unless it undercuts the price of water from existing sources, and improves water utilisation through promotion of micro-irrigation.

Parameter Value Percentile
Water Availability Index 0.55 41
Proportion of small and marginal cultivators 89% 59
Unirrigated net sown area as a share of total net sown area 1% 5

Promote 1 HP and sub-HP pumps

Not Suitable

The district has a rather high concentration of marginal farmers. But, a relatively low proportion of horticulture crops under gross cropped area, a comparatively low disbursement of institutional credit to marginal farmers, and groundwater availability below the safe limit make it extremely difficult to promote 1 HP and sub-HP pumps here. Such pumps can be promoted only if clubbed with micro-irrigation along with support to farmers for pump adoption and undertaking horticulture.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 2% 29
Water Availability Index 0.55 41
Proportion of marginal cultivators 70% 60
Medium and long term institutional credit disbursed in a year (in INR Crore) 0 0

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 – 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) 0 0

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 2% 29

National Mission on Oilseeds and Oil Palm (NMOOP)

The relatively low share of oilseeds and oil palm crops under gross sown area in the district makes it a suitable candidate for promoting NMOOP. Solar pumps could meet irrigation needs for these crops and help farmers diversify their yields beyond cereals.

Parameter Value Percentile
Area under oilseeds as a share of total cropped area 3% 39

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 0.47 62
