A Market-Based Economic Instrument to Better Use Water in Agriculture

Abstract

The paper presents a market-oriented system of returnable guarantees that can be combined with tradable permits to encourage farmers to use alternative sources of water instead of the regular watering network, or to steer the farming system toward environmentally-friendly systems like low tillage and/or organic farming. Factual data from real farming were bootstrapped to test whether or not a set of farms could save water and reduce chemical input due to the higher cost of maintaining the status quo. Based on interactions between water, pesticides, fertilizers, and crops, the system of returnable guarantee determines the farmers to reduce the amount of water harvested from aquifers, generates benefits for the most environmentally-friendly farmers, and stimulate conversion to organic farming.
