More Crop and Profit per Drop of Water: Drip Irrigation for Empowering Distressed Small Farmers

Abstract

In the light of the rapid decline in the irrigation water potential and increasing demand for water from different sectors in India, there is a need of the emergence of small-scale irrigation technology to conserve scarce water resources. Drip irrigation is one such technology that has been introduced to reduce water consumption in the agriculture sector, leading to sustainability of this sector. It allows farmers to cultivate crops without moisture stress even under water-scarce conditions, thereby increasing farm productivity. Earlier studies have analyzed the economics of drip irrigation in the case of high-value crops, which are mostly cultivated by rich farmers. Drip irrigation is also suitable for cultivating vegetable crops that are mostly cultivated by small farmers. However, in the Indian context, research on the effectiveness of drip irrigation is rare for these crops. We show that farmers cultivating green chilli could reduce the use of water by about two-thirds and increase productivity by more than half by adopting the drip irrigation method, compared to the same crop cultivated under conventional flood irrigation. The farm profitability too is impressive. The discounted cash flow analysis shows that the investment in drip irrigation for green chilli cultivation is economically viable even without the state subsidy. Despite such favourable outcomes, poor awareness prevailing among small farmers prevents adoption of drip irrigation. We suggest that there is a need to spread the benefits of cultivating vegetable crops under drip irrigation through a quality extension network on a continuous basis through various means. It would curtail the distress of the small farmers as well.

The impact of a Solar Market Garden programme on dietary diversity, women’s nutritional status and micronutrient levels in Kalalé district of northern Benin

“…This is consistent with our results suggesting that underweight started to improve in the middle-SES households who may have had the means to incorporate the SMG programme sooner. Finally, it is possible that drip irrigation systems such as the SMG, being a labour-saving energy access to pump irrigation water (26,48) , could reduce women's energy expenditure and thus partially explain the increase of BMI in the SMG WG group.…”

Impact of Drip Irrigation Technology on Input use and Productivity in Banana: Evidence from Gujarat

“…It is proved that a use of irrigation water and its management in scientific way help to increase the agricultural production many folds [5]. Drip technology enhances water use efficiency as potential water available for future use is declining with faster rate [6,7,8]. Area under micro irrigation was 572980 ha in India, out of which 355516 ha were under drip and 217464 ha was under sprinkler irrigation [2].…”

Fuzzy Mamdani Implementation for Hydroponic Water Content Automation

“…it has become one of the most common irrigation systems [2] , especially in arid and semi arid regions in Indonesia because of its advantages, more efficient in terms of water and electricity with automatic functions for the switch to turn it on and off. [3] Drip irrigation is one such technology that has been introduced to reduce water consumption in the agriculture sector [4]. So the advantage of this method is the use of highly efficient irrigation water [5].…”
