Interpretive Summary: Climate change strongly influences freshwater supply and demand globally. Groundwater is the world’s largest distributed store of freshwater, which is likely to play a vital role in enabling societies to adapt to intermittent and sustained water shortages caused by climate change. Groundwater is also essential to satisfy the increased demand for water to achieve many of the United Nations’ Sustainable Development Goals (SDGs), including zero hunger, water for all, and climate action. Aquifers transmitting and storing groundwater can also mitigate climate change through the use of geothermal energy to reduce carbon dioxide (CO2) emissions, as well as the capture and storage of emitted CO2. This chapter reviews the latest understanding of the impacts of climate change on groundwater quality and quantity. It highlights the opportunities, risks and challenges associated with groundwater development and management for climate change adaptation and mitigation.

Technical Abstract: Climate change strongly influences freshwater supply and demand globally. Warming of ~1°C over the last half century globally has directly impacted the supply of freshwater through the amplification of precipitation extremes, resulting in more frequent and pronounced floods and droughts, increasing evapotranspiration rates, rising sea levels, and changing precipitation and meltwater regimes. Groundwater, the world’s largest distributed store of freshwater, is well placed to play a vital role in enabling societies to adapt to intermittent and sustained water shortages caused by climate change. Groundwater is also essential to satisfy the increased demand for water to achieve many of the United Nations’ Sustainable Development Goals (SDGs), including specifically no. 2 (zero hunger), no. 6 (water for all) and no. 13 (climate action). Aquifers transmitting and storing groundwater can also contribute to climate change mitigation through the use of geothermal energy to reduce carbon dioxide (CO2) emissions, as well as the capture and storage of emitted CO2. This chapter reviews the latest understanding of the impacts of climate change on groundwater quality and quantity as well as the opportunities, risks and challenges posed by the development of aquifers in climate change adaptation and mitigation.
