Public acceptance of water reuse for agriculture in the wake of the new EU regulation: Early reflections

Domestic wastewater reuse in agriculture is often discussed as a way to tackle water scarcity in Europe. Europe could learn from the examples of other countries that are already successfully implementing wastewater reuse, especially in the Mediterranean. However, the potential of the practice is currently unfulfilled mainly due to social and legal barriers, including public resistance and the lack of a unified legislative framework at the European Union (EU) level. In the wake of the new EU Water Reuse Regulation released in June 2020, we wonder how this legislative intervention can foster public acceptance of non-conventional water reuse practices in agriculture. The original contribution of this piece is to provide a novel discussion of the transformations potentially triggered by the new EU Regulation and to suggest an innovative way forward, based on engaging interested users in water quality monitoring (i.e. water citizen science). We combine theoretical and empirical analysis, grounding our findings in an overarching theoretical concept, i.e. the neo-institutionalism theory. We conclude that the main catalysts for stimulating public acceptance can be identified in a unifying legislative tool represented by the recent EU Regulation and in the promotion of participatory water monitoring initiatives, also in line with the spirit of the EU Regulation
