Revisiting Ancestral Groundwater Techniques as Nature Based Solutions for Managing Water

Abstract:

To achieve water sustainability and a more efficient use of water we should base on the ancestral water and territory management knowledge and grained in the culture of the people, This work is inspired in Nature Based Solutions (NBS) for managing water availability, particularly groundwater and aquifer-related NBS that hold major unrealized potential for alleviating adverse impacts of progressive climate change, namely to increase water security/drought resilience. In some cases, more ecosystem-friendly forms of water storage, such as natural wetlands, improvements in soil moisture and more efficient recharge of groundwater, could be more sustainable and cost-effective than traditional grey infrastructure such as dams. The core of this study is centred in the pre-Inca and Inca civilizations and how these communities have developed ingenious NBS solutions to adapt to extreme climate scenarios such as prolonged droughts, managing water resources in a holistic way and how they understand clearly the global water cycle in all the components specially groundwater. The work is divided in three interlinked phases: to sow water, by implementing ancestral aquifer recharge solutions, to retain water by improve hydraulic efficiency in terms of infiltration and drainage and to collect water by improve the performance of extraction in the subterranean aqueducts in arid regions.
