Groundwater: The World’s Neglected Defence Against Climate Change

Year Published:
Resource Type:
Evaluations and Research

This report shows that groundwater, which exists almost everywhere underground, could save hundreds of thousands of lives and be the world’s insurance policy against climate change. The report also explains that while groundwater in sub-Saharan Africa is largely underused, in other parts of the world – mainly in south Asia – overuse is rife. The report emphasizes the need to increase water and sanitation financing for marginalized communities through a fixed percentage of annual government budgets and from international donors and the private sector. It also stresses that investment in responsible groundwater development – and the knowledge, expertise, finance, and institutional support this requires – is key to securing life-saving, sustainable, and safe water and sanitation for communities living on the frontline of the climate crisis.
