It has been suggested that Water security and emergency preparedness be merged into this article. (Discuss) Proposed since April 2010.

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.

It impacts regions, states and countries. Tensions exist between upstream and downstream users of water within individual jurisdictions.

During history there has been much conflict over use of water from rivers such as the Tigris and Euphrates Rivers.

Water security is sometimes sought by implementing water desalination, pipelines between sources and users, water licences with different security levels and war.

Water allocation between competing users is increasingly determined by application of market-based pricing for either water licences or actual water.

International competition

More than 50 countries on five continents are said to be at risk of conflict over water.

Turkey's Southeastern Anatolia Project (Guneydogu Anadolu Projesi, or GAP) on the Euphrates has potentially serious consequences for water supplies in Syria and Iraq..

Intra-national competition

Australia

Main article: Water security in Australia

Competition between regions

In Victoria, Australia a proposed pipeline from the Goulburn Valley to Melbourne has led to protests by farmers.

Competition between uses

In the Macquarie Marshes of NSW grazing and irrigation interests compete for water flowing to the marshes

Competition for environmental flows

The Snowy Mountains Scheme diverted water from the Snowy River to the Murray River and the Murrumbidgee River for the benefit of irrigators and electricity generation through hydro-electric power. During recent years government has taken action to increase environmental flows to the Snowy in spite of severe drought in the Murray Darling Basin. The Australian Government has implemented buy-backs of water allocations, or properties with water allocations, to endavour to increase environmental flows.
