Water security is the capacity of a population to ensure that they continue to have access to potable water. It is an increasing concern arising from population growth, drought, climate change, oscillation between El Nino and La Nina effects, urbanisation, salinity, upstream pollution, over-allocation of water licences by government agencies and over-utilisation of groundwater from artesian basins. Water security is rapidly declining in many parts of the world.
