Abstract This article reviews three managed aquifer recharge (MAR) sites in the Great Karoo, Northern Cape province of South Africa. The Karoo has limited surface water resources, and groundwater resources are therefore targeted for water supply. MAR systems show unique potential to reduce water scarcity in this area and to mitigate the impacts of climate change. MAR systems have been supporting groundwater supply to the communities in the Karoo since 2014, when a crippling drought has hit this area. In this article, we describe how drought affects the groundwater resources in the Karoo. We also assess the effectiveness of the operations of the three MAR systems to determine if these systems can be implemented at other sites around the Karoo, by considering chemistry and water level monitoring data for these three MAR systems. Small-scale MAR schemes are critical to climate change resilience when properly planned and managed.

在干旱期间通过管理含水层补给加强南非主要卡鲁的地下水补给

摘要 本文回顾了南非北开普省大卡鲁的三个受管理的含水层补给 (MAR) 站点。卡鲁的地表水资源有限，因此地下水资源是供水的目标。MAR 系统在减少该地区的水资源短缺和减轻气候变化的影响方面显示出独特的潜力。自 2014 年以来，MAR 系统一直为卡鲁社区的地下水供应提供支持，当时该地区遭受严重干旱。在本文中，我们描述了干旱如何影响卡鲁的地下水资源。通过考虑这三个 MAR 系统的化学和水位监测数据，我们还评估了三个 MAR 系统运行的有效性，以确定这些系统是否可以在 Karoo 周围的其他地点实施。
