Groundwater in International Law

Book excerpt: Groundwater represents about 97 per cent of the fresh water resources available on earth (excluding the water locked in the polar ice), and is of key social, economic, environmental and strategic importance. Aquifers (including numerous transboundary ones) are coming under growing pressure from over-abstraction and pollution, which seriously threaten their sustainability. This publication brings together a range of binding and non-binding international law instruments dealing with groundwater, an emerging body of rules that indicate a trend towards more comprehensive international regulation in this important field.
