In countries where scarce surface water causes disease and conflict, an abundance of water can bring peace.
With the growing impact of climate change, an estimated one third of the world''s population lacks fresh water. By 2050 it could well be over half, some five billion people.
Alain Gachet, known as the "Wizard of H2O", explores and unravels the interrelated humanitarian, environmental, scientific and geo-political concerns generated by water scarcity. An archaeological explorer and mining engineer, Gachet has developed a technology (using Nasa satellite imagery) to identify massive aquifers beneath the earth''s surface using a mathematical algorithm that could completely change our future.
As well as exploring our current environmental crisis (and offering some solutions), Gachet gives an account of his extraordinary adventures as a mining engineer both before and since he became an expert in deep groundwater - in Congo; in Libya, where he has an aud
