This model has the potential to improve irrigation equity as it avoids a prohibitively high upfront cost of technology for small and marginal farmers. The tool filters all districts where the ‘Score on Water Scarcity Index’ is greater than 0.75 to determine long-term economic viability. The tool also filters where ‘Proportion of small and marginal farmers’ is greater than 85, so they are the biggest takers and beneficiaries of this model. Finally, the tool filters all districts where ‘Unirrigated net sown area as a share of net sown area’ is greater than 50%. This helps find areas where there is a lack of access to irrigation and the opportunity to expand irrigation cover.
