what are the 4 different approaches to managing water?
hard engineering (artificial structures to increase supply)
sustainable water supply schemes (often soft engineering)
integrated drainage basin management (river basins being treated hollistically)
water sharing treaties (aiming to resolve the potential for hostilities over shared water)
hard engineering: desalination in isreal
a world leader in technology after solving its own acute water crisis
2018= the worst drought in 100 years, water reserves were nearly 0 but are now in surplus
water revolution was accomplished through conservation of water resources and new desalination plants
in 2007, low-flow toilets and showerheads were installed nationwide
the national water authority built innovative water treatment systems that recapture 86% of water that goes down the drian for irrigation: using grey water
since 2005 deslatination is 2.1 billion cubic metres annually
