Yemen’s valleys and farms are full of dangerous plastic waste | Environment News

Wadi Dawan, Yemen – From above, Wadi Dawan looks untouched – a ribbon of date palms winding through towering cliffs, divided by a white wadi bed. Scattered mud‑brick homes cling to the rocky slopes, overlooking one of Yemen’s most celebrated agricultural valleys, renowned for its palm dates and quality honey.

But continuing down into the valley, a starkly different picture emerges: plastic waste litters the flood channels, while the smell of burning rubbish hangs in the air, triggering coughs and polluting the valley’s once‑clean atmosphere.

“By God, this is a very serious problem,” said Yousef Abdullah, a 65‑year‑old farmer and orchard owner, speaking angrily to Al Jazeera. “If it remains unresolved, it will cause a disaster.”

Yousef stood beneath the shade of date palms, surrounded by a blanket of plastic bags, bottles, and food wrappers.

Throughout Wadi Dawan, home to thousands of people across dozens of scattered villages in Yemen’s eastern Hadramout province, plastic bags, bottles, and other household waste litter roadsides and palm groves.

Piles of rubbish – including dead animals – are dumped into flood channels that irrigate the valley’s farms. Household waste is mixed with sewage discharged into the wadi bed, while mounds of rubbish are dumped along roadsides just metres from people’s homes.

Yousef said that floods flowing through the valley pick up the waste, blocking irrigation channels, and depriving some farms of the vital waters they need. That has forced farmers to rush to the channels whenever the floods arrive, clearing the waste that has accumulated before the water recedes.

“We move from one irrigation channel to another leading to our farms, removing plastic bags, construction debris, and trees,” Yousef said. “We have to do it carefully because broken glass hidden in the rubbish can easily cut us.”

And then, after the floodwater recedes, Yousef and other farmers return to their fields and collect the plastic bottles and bags before they can sow their seeds.

Waste awareness initiative

Residents, environmental advocates, and local officials say the growing problem is driven by the lack of a proper waste collection system and limited public awareness of the environmental and health risks of indiscriminate dumping.

Large parts of the valley have no waste collection points at all. In the places that do, green rubbish bins can be seen along the roads, but are often overflowing. Garbage trucks are supposed to collect waste from the bins once a week, but the service is often disrupted because of a lack of funding and poor vehicle maintenance.

With almost no funding or resources, Salem Raji, who heads the Ministry of Agriculture’s office in Wadi Dawan and is also an agricultural researcher, launched an initiative to draw attention to the growing problem of waste dumping in his home valley. He has met with local officials, spoken to local media and used social media to warn residents about the environmental consequences of dumping rubbish into the valley’s flood channels.

“The agricultural sector is particularly affected by plastic waste, which contaminates the soil and leads to poor or even failed crop yields,” Raji said. “Waste causes numerous problems in the main irrigation canals, blocking water flow, damaging canal walls and preventing floodwater from reaching farmland. As a result, some farmers lose an entire harvest season because their fields receive no irrigation.”

The problem has worsened over the past decade as Yemen has been engulfed in a war between the Iran-backed Houthis and the Saudi-backed, internationally recognised government. The conflict has killed hundreds of thousands of people, displaced millions, and devastated state institutions, leaving local authorities, including municipalities and agricultural offices, with little funding or capacity to provide basic services.

“The problem has worsened in recent years because of the war, which has led to administrative instability and a lack of funding for local authorities,” Raji said.

Raji appeared frustrated that his efforts had yet to bear fruit and that his warnings had largely fallen on deaf ears, with residents continuing to dump waste across the valley. He called for an increase in his office’s monthly budget, currently just 8,000 Yemeni riyals, or about $5, so that staff could conduct field visits, reach more residents, and help remove rubbish from farms and flood channels.

Despite Raji’s best efforts, he has had little success with his attempts to raise awareness. “Our office’s [limited] budget leaves us unable to carry out regular field visits to educate the public or remove waste from flood channels.”

Expanding problem

The crisis extends far beyond Wadi Dawan. Across Yemen, years of war, collapsing public services and inadequate waste management have turned rubbish dumping into a growing environmental and public health problem.

In cities such as Taiz, waste has polluted farmland, contaminated drinking wells and dams, and increased the risk of waterborne diseases, according to local officials and health experts.

Dr Yassin Abdul Malik al-Shuraihi, who heads disease surveillance in central Yemen’s Taiz governorate, told Al Jazeera by telephone that the province, home to millions of people, suffers from a severe shortage of rubbish bins and chronic delays in waste collection.

As a result, many residents have resorted to dumping rubbish into flood channels that run through agricultural areas.

“Sewage, household waste and construction debris are now being dumped directly into these channels,” al-Shuraihi said. “We record a large number of diarrhoea cases throughout the year because sewage contaminates some drinking wells, making the water unsafe.”

Environmental experts are now calling for urgent action, warning of the particular dangers the waste poses to Yemen’s rural areas and farmland.

Khaled Saleh Bawahidi, a professor and director of the Environmental Studies and Water Resources Centre at Hadramout University, said indiscriminate waste dumping poses serious long-term environmental and public health risks.

“Accumulated waste is degrading natural habitats and polluting the soil around the palms, threatening tree growth and long‑term productivity,” Bawahidi said. “Bee health is also at risk as grazing areas deteriorate and the quality of natural resources declines. This could lead to a drop in the quality of dates and honey.”

And ultimately, it will be local Yemenis who face the consequences.

“Waste dumped in valleys contaminates soil and surface water,” Bawahidi added, “and creates breeding grounds for insects and rodents that can transmit diseases to humans and livestock.”
