The role of groundwater use in buffering the effects of climate variability on water supply is increasingly acknowledged. Today, 38% of agriculture production worldwide relies on groundwater and half of the world population living in megacities can be considered groundwater-dependent. In the case of Asian region countries, such as the host of the conference, these percentages of dependence are even higher. Ensuring the sustainable management of groundwater systems is critical in striving for water security.
Nature Based Solutions (NBS) are actions inspired by, supported by or copied from nature. They can be considered as the operation of nature in responding to challenges such as climate change, food security, water resources, or disaster risk management, including a wider definition of how to conserve and use biodiversity in a sustainable manner.
NBS can serve as a cost-effective approach for regions to reduce or buffer the negative impacts of intensive groundwater use, while at the same time enhancing supply, resiliency and protecting groundwater-dependent ecosystems, among other co-benefits.
