An Analysis of Farmers’ Propensity to Use Reclaimed Wastewater in Agriculture

In the Mediterranean Basin, increasing water scarcity, exacerbated by climate change, necessitates the use of alternative water resources in agriculture. This study analyses farmers’ propensity to use reclaimed wastewater for irrigation in Basilicata, a region in southern Italy. Through a survey of 167 farms and the application of a logit model, this work quantifies the role of the main factors influencing farmers’ propensity to use this new resource. The results identify several key drivers and barriers. A higher level of education and participation in Producers’ Organisations make wastewater use approximately ten times (odds ratio equal to 9.84) and five times (odds ratio equal 4.96) more likely, respectively. Furthermore, an adequate knowledge of the relevant legislation nearly quadruples (odds ratio equal to 3.57) the likelihood of adoption. In contrast, concerns related to worker health and groundwater pollution are strong deterrents, reducing the odds of adoption by 90% and 87%, respectively. Concerns about product quality also significantly decrease the propensity to adopt (odds ratio equal to 0.25). The findings underscore the need for integrated interventions that enhance farmers’ awareness and knowledge of the characteristics and impacts of new practices, thereby fostering the innovative and sustainable management of water resources.
