Water Resources

Every theme on this platform rests on the same physical base: how much water the region actually has, where it sits, and who else has a claim on it. The headline is stark. This is the most water-scarce region on earth, home to 6% of the world's population and less than 2% of its renewable water supply.³ The detail matters more, because most of the significant water is shared, flowing in from outside, as the Nile and Euphrates do, or lying in aquifers that ignore borders.

The definitive map of what is shared is the UN-ESCWA and BGR inventory, which catalogues nine transboundary surface-water basins and seventeen shared aquifer systems across Western Asia, and finds more than 70% of the study area sitting in one of them.¹ Two of its conclusions frame this whole hub. There is not a single basin-wide agreement on shared water in the Middle East, and there are no specific agreements on shared groundwater at all, though a few bilateral treaties carry groundwater clauses.¹ The satellite record supplies the trend line. Between January 2003 and December 2009, the Tigris, Euphrates and western Iran lost 143.6 km³ of stored fresh water, about 91 km³ of it groundwater.²

The spread is enormous. Turkey generates about 2,700 m³ of renewable water per person a year and Iran about 1,450; Kuwait generates none at all inside its borders.⁵ Between them sit the river states, whose apparent abundance depends on upstream goodwill: 98% of Egypt’s renewable water originates outside the country, 72% of Syria’s and 61% of Iraq’s.⁶ Below them all is the scarcity belt, from Jordan and Palestine to Yemen and the Gulf, living far under the 500 m³ absolute-scarcity line. The dashboard below maps the per-capita picture. The darker the country, the thinner the margin.

The hub's headline metric for all twenty countries. Hover, tap or focus a country; the ranked table sits alongside.

What each country has, and where it comes from

Ranked from the scarcest upward. The third column is the share of a country’s renewable water that originates beyond its borders, which is the number that turns hydrology into diplomacy.

Sources: World Bank World Development Indicators for 2021, drawn from FAO AQUASTAT, for internal renewable water per person and withdrawal as a share of internal resources; FAO AQUASTAT country factsheets for the dependency ratio. Per-person figures count only water generated inside the country, which is why Kuwait reads zero. A withdrawal share above 100% means a country is living on rivers from abroad, on fossil groundwater, or on the sea.

Twelve of the nineteen countries with a published figure withdraw more each year than their own territory renews.⁵ Egypt is the extreme: 77.5 km³ withdrawn against internal resources of about 1 km³, the arithmetic of a country living on a river that rises 6,000 km away.⁵⁶ The World Bank prices the current path at 6 to 14% of regional GDP by 2050, and expects water per person to fall below the absolute-scarcity line by 2030.⁴ Agriculture takes 83% of the region’s withdrawals, against a world average of 70%.⁴ The denominator keeps shrinking, with FAO reporting renewable water per person down a further 7% over the past decade.⁷

One scheme in this sector, examined in full: what was built, what it cost, what worked and what did not.

Rivers, lakes, reservoirs and major dams across the region, drawn on the same layers as the Region Atlas. Hover a river, lake or dam for its name; zoom with the buttons, a pinch or ctrl-scroll.

Only the principal rivers and the larger lakes, reservoirs and dams are shown. Lakes and reservoirs: HydroLAKES v1.0; major dams: FAO AQUASTAT. Transboundary aquifers, river basins and tracked projects are layers of the full atlas.

Four kinds of water carry the region, and they behave differently enough that treating them as one supply is the commonest planning error made here.

The great transboundary rivers

The Nile, the Tigris and Euphrates, and the Jordan. All are fully allocated and then some. The Lower Jordan is the end state: annual flow has fallen from more than 1.3 billion m³ to less than 30 million, with 96% of its fresh water diverted.¹⁰

The asymmetry is physical before it is political. Between 88% and 98% of the Euphrates’ runoff is produced in the highlands of south-eastern Turkey, while the Tigris draws an estimated 32 to 50% of its discharge there and the rest from Zagros tributaries in Iran and Iraq.¹¹ Turkish dams alone can retain the equivalent of 137% of the Euphrates’ average annual discharge at the Syrian border, and 92% of the Tigris’.¹¹

Iraq is the clearest current case. Tigris and Euphrates flows run about 30% below their 1980 level.⁸ The Green Iraq Observatory put the country’s 2025 receipts at 35% of the share it claims.⁹ National live storage fell to about 3.5 billion m³ before the 2025–26 winter and recovered to about 20 billion after it, which the United Nations calculates as roughly a quarter of what has been lost since 2020.⁸

Renewable aquifers

The highland and coastal groundwater that most cities and farms actually pump. It recharges, but across the region it is abstracted well beyond safe yield, which converts a renewable resource into a depleting one.

Morocco’s Souss is the instructive record. One upstream piezometer fell 1.9 metres a year between 1998 and 2008 and 3.5 metres a year between 2012 and 2020, and across the basin the correlation between the rainfall index and the groundwater index is 0.07.¹² Rain is not what is driving that.

Fossil aquifers

The Nubian Sandstone beneath Egypt and Libya, the Saq-Ram or Disi system shared by Jordan and Saudi Arabia, and the Umm er Radhuma beneath the Gulf. Vast, ancient and not meaningfully recharged at the depths being pumped, so anything taken is taken once.

The Saq-Ram sandstones cover about 560,000 km², 82,000 of them in Jordan and 478,000 in Saudi Arabia.¹³ Jordan’s measured draw in the Mudawwara-Disi area is about 60 million m³ a year, against a conveyance built for 100 million.¹³ The Saudi side shows what unmanaged mining looks like: abstraction around Tabuk rose from about 29 million m³ a year in 1983 to between 1,050 and 1,700 million by 2004, against recharge of 3 to 10 million, and water levels fell by up to 32 m a year in the late 1980s.¹³ The inventory’s own verdict is that the exploitable resource may be exhausted within 30 to 40 years unless abstraction is controlled on both sides of the border.¹³ A technical memorandum in 2007 barred new production wells within 10 km of that border, and a formal agreement followed in 2015.¹³¹⁸

Manufactured water

Desalination and treated reuse: the only line on the regional supply sheet that grows. It also moves water from a hydrological constraint to an industrial and financial one, which is a different kind of exposure rather than the absence of exposure.

The buffer behind it is thin. Qatar, which has invested more than most in storage, reported reserves equal to 5.2 days of supply in 2024, and the UAE’s strategy targets national storage of up to two days.²⁰²¹ A manufactured supply is only as secure as its power, its intakes and its politics.

Dependency is the system’s defining feature. On FAO’s accounting, Kuwait draws 100% of its renewable water from outside its borders, Egypt 98%, Bahrain 97%, Syria 72%, Iraq 61% and Israel 58%.⁶ Water diplomacy in this region is not a policy choice but a hydrological fact.

Where to read next, by situation:

Jordan (exemplar report: the full scarcity playbook), Egypt (one river, one hundred million people), Iraq (upstream dependence in crisis), Yemen (groundwater emergency), Kuwait (life at 6 m³ per head), Turkey (the region's upstream water tower).

Three resource stories that define the era:

Wetlands are where a water budget becomes visible. Two of the region’s great ones were drained inside a single generation.

The Mesopotamian marshes covered 8,926 km² in 1973–76 and 1,297 km² by 2000, 14.5% of what they had been, with most of the loss falling between 1991 and 1995.¹¹ The Central Marshes came down to 3% of their 1973 extent and Al Hammar to 6%.¹¹ The economic loss ran downstream: FAO estimated in 1990 that 60% of Iraq’s inland fish catch came from the marshes, and up to 40% of Kuwait’s shrimp catch originates there.¹¹ Re-flooding after 2003 returned part of the system, and UNESCO inscribed the Ahwar of Southern Iraq in 2016.¹⁹

Jordan’s Azraq oasis shows the groundwater version of the same story. Discharge from the four springs that fed it ceased completely after a large well field was created in 1980.¹⁴ Abstraction in the basin has reached 215% of the 24 million m³ safe yield, from 960 wells drawing 51 million m³ in 2009, and farms have been abandoned since 2004 as levels fell and salinity rose.¹⁴ There are no formal water agreements for the basin, which Jordan shares with Syria.¹⁴

The renewable base will not grow; the population will, from just over 100 million in 1960 to more than 450 million in 2018 and a forecast 720 million by 2050.⁴ Closing the gap is arithmetic with four terms: desalinate, reuse, save, and import water as food. Every national strategy in the region is some weighting of them.

The file to watch is groundwater. It is the buffer everything else leans on, and it is falling almost everywhere it is measured. Across Iran’s aquifers, satellite gravimetry shows an average depletion of 29 cm a year between 2002 and 2023.¹⁵ Globally, groundwater now accounts for 68% of the water lost from non-glaciated land, and dry regions are drying faster than wet ones are wetting.¹⁶ The rivers add a second kind of risk: Nile modelling projects a 63% rise in the 100-year peak discharge under a middle scenario, and 85% under high emissions, so the same basins face both deeper droughts and bigger floods.¹⁷
