Why Groundwater Is One of Our Most Precious Resources
From the Murray-Darling system to Great Artesian Basin, “invisible” underground groundwater is often the only water supply available across the vast majority of Australia—and its annual contribution to GDP is estimated at more than $6.8 billion a year.
However, overuse of groundwater during droughts and aquifer depletion has led to water crises, including in Australia’s “food bowl” the Murray-Darling Basin (MDB), California and Cape Town in South Africa, with more likely to follow as groundwater management is largely reactive and unlikely to avert more crises as climate change and population pressures grow.
