Tequila, bats, and agave farmers: towards an understanding of the right incentives to protect genetic diversity

Abstract

Tequila has a designation of origin by which it can only be produced with the blue agave (Agave tequilana Weber blue variety) grown in certain regions of Mexico. For several decades, an intensive asexual technique of reproduction has prevailed in the tequila industry. This has not only been detrimental for the agave’s genetic diversity, but it has also harmed bat populations. The low levels of diversity have increased the agave’s exposure to pests and diseases and have limited the possibilities for artificial selection of beneficial characteristics that can improve production. Arguably, with the cooperation of producers and consumers, it is possible to have an environmentally friendly and resilient production system. We focus on the agave producers and analyze their willingness to let some of their plants flower in exchange of some monetary and non-monetary benefits. By analyzing data from a choice experiment, we show that farmers are willing to let some of their plants flower even when they only receive partial compensation for the value of the plants. Farmers also show a willingness to participate in a conservation program if they receive a non-monetary transfer or expect an increase in yield because of the program. Our results provide a relevant piece of information that can help policymakers, producers, NGOs, and other participants in the tequila industry, in the design of effective strategies that can lead to the genetic conservation of blue agave and the protection of magueyero bats.
