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, 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 naturally well placed to play a vital role in enabling societies to adapt to intermittent and sustained water shortages caused by climate change. It is also essential to satisfy the increased demand for water in order to realize many of the United Nations’ Sustainable Development Goals (SDGs), including no. 2 (zero hunger), 6 (water for all) and 13 (climate action). Aquifers transmitting and storing groundwater can also contribute to climate change mitigation through the use of geothermal energy to reduce 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 quantity and quality as well as the opportunities, risks and challenges posed by the development of aquifers for climate change adaptation and mitigation.
