Overview on managed aquifer recharge in Brazil

Groundwater has a significant relevance in Brazil as almost 90% of all rivers rely on baseflow from aquifers who feed them during the dry season. Under climate changing conditions and increasing demand, managed aquifer recharge (MAR) represents an important adaptation measure to sustain the hydrological cycle. To assess these experiences in the country and their potential for strengthening the sustainable management of water resources, the Brazilian project partners published in April 2020 an overview on MAR practices in Brazil. The paper is based on a systematic literature review with the goal of understanding the challenges and opportunities of MAR adoption in the country as part of wider IWRM strategies. The paper concludes that, despite pilot initiatives and academic studies, Brazil is still at an early stage and has plenty of potential and opportunities for further development of full-scale MAR schemes.
