CMEC Director Charlotte Leslie talks Ex-Defence Secretary Sir Liam Fox about the growing global water crisis - the subject of Sir Liam's latest book, "The Coming Storm, Why water will write the 21st Century."
The combination of an ever-increasing global population, climate change, industrialisation, urbanisation and limited natural resources means that one difficulty, above all, will shape the political, economic and security environment in the years ahead: that is water.
By 2030, an astonishing 47 percent of the entire global population will live in high water stress areas. It is inevitable in conjunction with rising global temperatures - that water shortages will drive future conflict and migration.
Water is finite and more than 97.2 per cent of it is undrinkable sea water. Desalination creates highly toxic brine that cannot be dumped into the sea. From the Jordan basin to the River Nile, water is becoming ever more precious, ever more important and ever more fought over.
In a fascinating interview, Sir Liam talks about the possible future solutions to this growing crisis - he rightly describes as The Coming Storm.
