All in all Turkey’s climate is defined as semi-arid, whereas nine types of climate are observed mediterranean climate, wet mediterranean climate, partially wet mediterranean climate, Black Sea climate, Partially wet Marmara climate, steppe climate, partially dry central anatolian climate, partially dry south east anatolian climate and continental east anatolian climate

Uncontrolled use of groundwater resources in the regions with insufficient amount of surface water (rivers and lakes) stands out as another challenge. Use of illegal wells for groundwater extraction is a major issue. Despite the legal regulations on wells, the problem related to illegal wells cannot be solved because of the inadequate sanctions and inspection. The groundwater resources are subject to intense use for agriculture purpose. Because of over-extraction, most of the groundwater resources are under the threat of extinction.

The Euphrates-Tigris basin is among the most important river basins in Turkey and in the Middle East. The average annual discharge of the Euphrates and Tigris rivers is 84 billion m3, which equals to the average annual flow of the Nile River. Euphrates provides 90 per cent of water, whose average annual flow is 32 billion m3, from Turkey.

The total usable water potential of Turkey is 112 Billion m3 of which 98 Billion m3 is surface water and 14 Billion m3 is groundwater. In order to monitor groundwater extractions and prevent overuse, a regulation on groundwater measuring was enacted in 2011.

It is essential to take immediate measures to prevent potential water shortage. Thus, demand-oriented management should be the focus rather than supply-oriented management. Demand-oriented management is provided by efficiently using water resources through limiting demand on water, and setting institutional, economic and administrative incentives to save water. It is essential for water resources management to be flexible and effective enough to adapt to changing climate conditions, dry spells, and new precipitation patterns.

To mitigate water scarcity, the countries of the MENA region have substantially increased their investment and participation in desalination. There is no single model for desalination, nor can one model be applied in all the countries.

The political climate in the Middle East makes it impossible to discuss water without addressing the political contexts that have shaped its availability.

The population of Jordan has risen substantially over the last 60 years, from around 470,000 in the early 1950s to 6.2 million in 2010, a figure that is expected to double in the next three decades.

Around 92% of Lebanon’s sewage flows into rivers and the sea untreated. Wastewater management is fragmented, with responsibility for project planning and implementation (treatment facilities and connections to networks) split between the CDR, water establishments and municipalities.

Israel’s population has grown from an estimated 806,000 inhabitants in 1948 to around 7.73 million people in 2013 – an increase of more than 800% in 67 years.
