When in 1997, Dutch filmmaker Josepha Wessels arrived in Shallalah Saghirah, a small village on the fringe of the Syrian steppe southeast of Aleppo, it was like stepping back hundreds of  years. “There were all of these wonderful little, white-painted beehive houses,” she says. “It was very rustic and had no electricity supply.” The most remarkable historical artefact, however, was beneath Wessels’ feet. The village’s water arrived via a series of tunnels that were constructed not hundreds but 1,600 years ago. “To some people it sounds dull but the qanats really excited me,” Wessels says.

Qanats were first laid down during the Byzantine-Roman era (395 to 1453CE). They consist of a series of porous subterranean wells connected by gently sloping tunnels that use the force of gravity to transport water to the earth’s surface. They were traditionally used to provide a reliable supply of water to human settlements and to irrigate fields in hot, arid and semi-arid environments.

“In Greek and Roman times the qanats played a key role in the development of empires and thriving cities such as Palmyra,” Wessels, who went on to author a PhD on the topic, explains. Spreading with the Persian empire from south to Egypt and and as far east as India, qanats – also known as kariz – fell out of use from the 1960s on with the advent of diesel-driven pumps and private wells. 

But could they be the answer to the Middle East’s water woes? Today a combination of that 20th century over extraction and climate change has led to a crisis for water tables in the already drought-prone region. Although Wessels warns against a facile link between drought and political instability, a 2020 report by the University of California argues that a severe drought, worsened by a warming climate, drove Syrian farmers to abandon their crops and flock to cities, helping to trigger today’s brutal civil war. 

In troubled Syria and in Iran, Jordan and Oman, water shortages are an increasing threat to both livelihoods and liveability.

Wessels’ chance trip led, in the summer of 2000, to a participatory project in which a small group of Shallalah Saghirah villagers cleaned and renovated their village qanat. Wessels, with colleagues including her hydrologist husband Robertus Hoogeveen, went on to lead similar community-led renovations of qanats in towns including in Al Dumayr, a city located 45 kilometers north-east of Damascus, and Qara near to the border with Lebanon with funds from, amongst others, the Netherlands Government. Wesssels soon found that although over pumping by mechanical means was a feature of qanats falling out of use, often they had simply become blocked with calcareous deposits or debris as communities lost to knowledge, or will to maintain them.

“Qanats are simple technology, but every ten years or so they need to be cleaned out, relined so they don’t collapse and desilted,” Wessels says. “Importantly, you cannot do this without the community working together.” Wessels adds that whilst Iran still boasts individuals capable of building qanats – known as muqannis, and often trained by their fathers – Syria now lacks these traditional skills, and thus relies on ancient qanats laid down hundreds, or in some cases thousands, of years ago.

There are obvious attractions in reverting to this ancient water extraction system in our turbulent, heating times. Qanats have the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, they are almost insensitive to levels of precipitation, delivering a flow with only gradual variations from wet to dry years. The abandonment of qanats is a warning sign that groundwater in a region is being overexploited, says Majid Labbaf, who has worked on the reconstruction of qanats in Iran, Iraq and Azerbaijan. “The drying up of the qanats is an indication of a disconnection between humans and their natural environment,” he says.

Sadly, the city where Wessels original renovation took place is today abandoned due to Syria’s long civil war, although qanats in Al Dumayr and at Qara are still in operation. Wessels hopes that should inhabitants return to Shallalah Saghirah, they’ll find its ancient qanats will still be able to provide sufficient water for community life. Wessels also welcomes bids to recognise qanats as prime examples of Islamic heritage for example in the case of the UNESCO world heritage listing of Persian qanats in Iran. For successful restoration, state actors also need to be involved, she says, as qanats have to work in tandem with modern piped water systems. This, she adds, is not just a case of returning to the ‘old ways’.

“By rehabilitating the qanat system in combination with efficient groundwater management measures water resources, in Syria and elsewhere, can be saved for future generations,” she said. “But for that you need political will, and you need peace.”

In the 16th century, when the Portuguese sailed to the Arabian shores, they were enamoured by the plentiful, fresh seafood available along Oman’s 3,000 km coastline. Today, the sultanate of Oman is looking to revive this historic industry to reduce its dependence on the declining oil sector. “Fish farming has an untapped potential due to Oman’s geographical location. Agriculture and Fisheries is the second largest industry, therefore, it is natural that the government considered investing in it to decrease the reliance on oil and gas”, says Rumaitha Al Busaidi, an Omani environmentalist. The idea is sound, but its implementation has so far been marred by the lack of advanced technological implementations in Omani fisheries. Farmers still rely on the indigenous Falaj irrigation system, developed in 500 AD and used till date, which carries water from the natural springs to the mountain villages for farming and aquaculture. While it might have worked in the past, today this is problematic.

“Our fish production quality suffers because the water used for fish production and farming gets mixed with the saline water from the ocean, dramatically decreasing our income”, complains Khalifa Al Sahabi, a fish farmer in Bidiyah town in the Sharqiyah region.

To address this issue, Al Busaidi has introduced the concept of integrated Recirculating Aquaculture Systems (RAS) in aquaculture farms. These use mechanical and biological filters to reuse the water in production and minimise water resources for organic aquatic farming. “RAS technology also protects the marine environment”, she explains, “by restricting the effluent that reaches the ocean.” The Oman government had implemented this technology initially for the production of Tiger prawns. Food lovers and industry experts laud their size and quality. RAS technology has helped in increasing the production rate of these prawns even as it has made intensive fish production compatible with environmental sustainability. In May 2021, Oman invested in the construction of a 8,000 hectare aquaculture farm: the second largest in the MENA (Middle East and North Africa) region.

A number of barriers had to be overcome for the RAS technology to be implemented. Costs of installing temperature controls in the desert kingdom are high and it has been tricky to persuade local farmers to choose this newer technology over their traditional aquaculture methods. It has taken extensive educational drives by the Omani government to finally develop 21 integrated tilapia farms, one shrimp farm, and one marine cage farm in the country. Today, the figures speak for themselves. The production of tilapia has leapt from three tonnes in 2013 and five in 2014 to 20 tonnes in 2015 and 77 tonnes in 2017.

“With the help of RAS, we have successfully enhanced the fish quality by 66 percent across the country in the last six years”, says Nasser Abdullah, Assistant Project Manager of the Al-Wusta fish farming project. Next on the cards: using RAS technology for salmon production. While energy intensive, this sustainable aquaculture model is ensuring safer fishing techniques and lowered food miles for fish consumers across the Middle East.
