Yemen’s Vanishing Wells

Yet in a small number of places, new pumps powered by the sun rather than diesel have begun to hum again, offering not abundance, but continuity.

With the collapse of formal supply systems, water collection has increasingly shifted to the household. What once flowed through communal taps is now carried by hand, measured in plastic jerrycans and daily trips to increasingly distant springs and tanker points. Each jerrycan adds a physical burden, one that quietly pulls girls and young women out of school to help their families secure water. Where predictable supply returns — even briefly — the burden eases, and routines resume.

Yemen is one of the most water-scarce countries on Earth. Annual per-capita water availability has fallen to roughly 83 cubic metres, far below the international scarcity threshold of 500 cubic metres. In some regions, groundwater levels are dropping by one to eight metres every year. Wells that once sustained entire villages now yield brackish water or nothing at all.

Agriculture, which consumes more than 90 per cent of Yemen’s water, has become both victim and driver of the crisis. Qat — a mild narcotic leaf chewed daily by millions — dominates farming in many areas. It is lucrative, politically protected, and brutally water-intensive. As governance collapsed, unlicensed wells multiplied, allowing aquifers to be drained far faster than nature can replenish them. 

War accelerates the collapse

Yemen’s water crisis predates the war, but the conflict that erupted in 2015 sharply accelerated its collapse. The fighting grew out of the failed aftermath of the 2011 Arab uprisings, which left a fragile political transition, unresolved regional grievances, and a hollowed-out state.

Now, nearly half of the country’s water infrastructure — pumps, pipes, reservoirs, treatment plants — has been damaged or destroyed. Fuel shortages cripple what remains. Spare parts are scarce or unaffordable. Municipal salaries go unpaid.

At the same time, Yemen’s economy is in a continuous crisis.

Currency devaluation and blockades have erased household savings, leaving families unable to buy trucked water when taps run dry. Climate change compounds everything. A UN report says that according to some future scenarios, temperature rises of 1.2°C to 3.3°C by 2060 could increase the rate of water depletion and desertification. Rainfall has become erratic, and salinisation is swallowing fertile land.

‘Nature and man are squeezing Yemen from both sides,’ former prime minister Abdul Karim al-Eryani warned as early as 2008. Few listened, and the squeeze has only tightened.

Displacement without water

Many now facing water scarcity fled bombs, not drought. Displaced families in camps like Yakhtol face drying water points, absent tankers, and hours-long walks that often end empty-handed. Livestock have died, crops have failed, and children miss school as survival takes priority.

Yemen is now home to more than 4.8 million internally displaced people, many concentrated in areas with fragile or nonexistent water systems. The strain fuels tension between displaced families and host communities competing for the same wells, trucks, and aid distributions. For those who can still access trucked water, the cost is crushing. 

Yet even in displacement settings, progress is possible. In several camps, solar-powered pumping systems and rehabilitated boreholes have replaced diesel-dependent infrastructure, restoring predictable water access despite fuel shortages. Where water becomes reliable — even for a few hours a day — families report fewer disease outbreaks, children return to school, and tensions with host communities ease. These gains are limited and uneven, but they demonstrate that water access can stabilise daily life even in conflict.

Importantly, water scarcity is central to Yemen’s hunger crisis. By early 2026, more than half the population is expected to face acute food insecurity. Around 3.5 million women and children are already malnourished. In at least four districts, humanitarian agencies warn that famine-like conditions are looming. Without sustained access to safe water, food assistance alone will not be enough.

Yemen’s crisis reflects a wider pattern. As climate stress intensifies and governance falters, the world is entering an era of ‘water bankruptcy,’ with nearly four billion people facing severe shortages each year. 

Data from the Pacific Institute show water-related violence nearly doubling between 2022 and 2024. Yemen’s lesson is not that scarcity inevitably produces war, but that where institutions are weak, it sharpens every existing fault line — and that where water systems are protected, recovery remains possible.

The last walk

In 2026, the war in Yemen continues in a quieter but no less destructive phase. Frozen front lines, unresolved politics, and Red Sea tensions are disrupting fuel and spare-part imports, further straining water systems. Yet, despite affecting more than 18 million people, Yemen’s water crisis remains largely invisible. Access for journalists is dangerous and restricted. Warring parties impose blockades and intimidation. 

Donor fatigue compounds the problem. After more than a decade of war, Yemen competes for attention with newer crises in Ukraine and Gaza. Water, slow and uncinematic, rarely breaks headlines. Underreporting fuels underfunding, which deepens collapse. The tragedy, however, is not inevitable.

Across the country, practical solutions already exist. Rainwater harvesting — once central to ancient Yemeni civilisations — can be revived through terraced fields and small dams that recharge aquifers. Solar-powered pumping systems have been established in some displacement camps by UNICEF, the IOM, and local partners.

Long before the war, Yemenis built resilience into the landscape itself. Terraced fields and stone barriers once captured rainfall, recharged aquifers, and protected fertile soil. In a few mountain districts, communities have begun restoring these systems. The gains are modest but cumulative, and a UNDP assessment suggests that broader climate-resilient strategies could avert up to $93 billion in economic losses by 2060.

Along the coast, desalination could supply urban centres if political and financial barriers are overcome. Agricultural reforms, especially reducing qat cultivation, would free vast quantities of water currently locked into an unsustainable crop. These are not speculative ideas. What has been missing is the stability and political will to move beyond pilot scale.
