We evaluate a series of social and environmental challenges that MAR systems contribute to solving, as well as their attributes that diminish the expected impacts of CC in the study area. We show through the Los Arenales MAR systems (Central Spain) that MAR is a low-regret CC adaptive measure.

Nonetheless, few examples explicitly prove this point. MAR is often mentioned in the literature as a CC adaptation measure. Managed aquifer recharge (MAR) is a term that includes a series of techniques that enhance groundwater storage for later use or environmental purposes. A sound bridge between both approaches is low-regret adaptive measures, which result in win-win scenarios, as they provide solutions to current pressures and contribute to building CC adaptive capacity. Two approaches are commonly used to formulate adaptation measures, namely bottom-up and top-down, each with inherited limitations. In view of heightened climate change (CC), adaptation strategies are imperative to diminish the impacts on social and environmental assets.
