The broad leaves and delicate purple flowers floating on the Euphrates look breathtaking — but they are suffocating the waterways of Iraq, celebrated as the “land of the two rivers.”
The water hyacinth, nicknamed the “Nile flower” in Iraq, is an invasive plant native to South America’s Amazon basin that has ravaged ecosystems across the world, from Sri Lanka to Nigeria.
The fast-spreading pest poses a special risk in Iraq, one of the world’s hottest countries that is already suffering from regular droughts and shrinking water resources due to overuse, pollution and upstream river dams.
The exotic flower was introduced to Iraq just two decades ago as a decorative plant, but now the mighty Tigris and Euphrates rivers are being choked by its rapid spread.
Its glossy leaves form a thick cover, absorbing up to 5 liters of water per plant per day and blocking sunlight and oxygen vital to the aquatic life below.
That has made the hyacinth a formidable floral foe for Iraq’s fishers, who sell hauls of river carp in local markets to those cooking masgouf, a national delicacy.
Because of the infestation, carp are dying and fishing nets get caught in the tangle of flat leaves, roots and flowers that also hampers boat travel.
“Our livelihoods are gone, all because of this Nile flower,” said Jallab al-Sharifi, a fisherman in the southern province of Dhi Qar who makes his living on the Euphrates.
Another fisherman east of Baghdad who works the Tigris said his haul had dropped by as much as half.
The hyacinths have also affected Iraqi farmers who already struggle with low water levels due to a series of dams built further upstream in Turkey and Iran.
The thick floating vegetation draws down water levels and clogs irrigation channels leading to agricultural fields.
“During this harvest, our vegetable sales in the local market were down by a third,” said Ahmed Yasser, a farmer in a village near Kut, east of Baghdad.
The hyacinth causes another type of pressure — a 100 square meter patch can weigh up to 5 tonnes, putting major strain on dilapidated riverside infrastructure, Iraqi officials warn.
In the village of al-Badaa, the thick columns of a brick bridge that once spanned a wide stretch of the Euphrates are now covered by hyacinths.
A dam further upstream encloses a swamp-like patch of land also covered by the plant.
If the flowers are not removed, “the bridge and dam of al-Badaa will collapse,” said Jalil al-Abboudi, the village sheikh.
“And if they collapse, the whole water supply system will collapse,” he said.
That would deprive vast regions — all the way to Iraq’s southernmost province of Basra — of the fragile water resources their ecosystems and economies rely on.
Iraq’s oil-dependent economy is already projected to shrink by nearly 10 percent this year, according to the World Bank.
A health crisis sparked by a shortage of safe drinking water in the south hospitalized about 100,000 people in 2018.
Locals blame authorities for what they say have been years of neglect and insufficient maintenance.
“The lack of action by the ministry of water resources, and the fact that there have been no renovations of infrastructure, caused an invasion that reached potable water reserves,” al-Abboudi said.
Saleh Hadi, head of research at Dhi Qar’s agriculture directorate, said that the ministry was well aware of the dangers and working hard to mitigate them.
“The ministry of water resources is working to combat this plant mechanically by uprooting it from irrigation channels,” he said.
The perennial predicament this year has been made even worse because of the COVId-19 pandemic.
Under normal conditions, Iraqi villagers along the banks of the Euphrates pluck out the plants by hand instead of using a chemical agent that would destroy the delicate ecosystem.
This year, a countrywide lockdown imposed to stem COVID-19 infections has allowed the hyacinth to spread mostly unhampered.
Some vigilantes are defying the curfew to fight the parasitic flower which they see as a bigger threat to their livelihoods than the pandemic.
While villagers are sneaking out to uproot the plants by hand, Mohammed Kuwaysh, an environmental activist and member of a farming cooperative, is thinking even bigger.
His collective raised about US$800 from local farmers to equip small speedboats to clear waterways by cutting hyacinths en masse.
“The government isn’t listening, which allowed this flower to spread like wildfire,” Kuwaysh said.
Cambodian fishers on the Mekong River got a shock when they inadvertently hooked an endangered giant freshwater stingray 4m long and weighing 180kg, scientists said yesterday. The female leviathan, one of Southeast Asia’s largest and rarest species of fish, was caught by accident last week in Stung Treng Province when it swallowed a smaller fish that had taken a baited hook. An international team of experts on the US-funded Wonders of the Mekong project worked with the fishers to unhook the ray before weighing and measuring it, and returning it unharmed to the river. The Mekong is a crucial habitat for a vast
A tweet by Elon Musk saying Japan would “eventually cease to exist” without a higher birthrate yesterday set off a flood of sarcasm and anger — but much of angst was aimed at a Japanese government many said has done little to address the issue. Musk, the head of electric vehicle maker Tesla Inc, on Saturday wrote on Twitter: “At risk of stating the obvious, unless something changes to cause the birth rate to exceed the death rate, Japan will eventually cease to exist. This would be a great loss for the world.” The comment hit a nerve among Japan watchers and
The head of Australia’s foreign intelligence service has used a rare public address to suggest that an increasing number of disillusioned Chinese officials are willing to cooperate with the agency. Australian Secret Intelligence Service (ASIS) director-general Paul Symon addressed a range of topics related to Australia’s foreign intelligence operations, including the recent Solomon Islands-China security pact and the need to recruit new spies “with more vigor and urgency” than ever before. Speaking at a Sydney event hosted by the Lowy Institute to mark ASIS’ 70th anniversary, he said the audience, which included high ranking members of Australia’s intelligence community and top diplomats,
A glimpse of a possible Picasso in the home of Imelda Marcos filmed during a visit by her son after his presidential election win has set off a flurry of speculation in the Philippines, where the family that once plundered billions is set to return to power. Ferdinand “Bongbong” Marcos Jr, the son and namesake of the late dictator, won a landslide victory in Monday’s presidential election, an outcome that has appalled those who survived his father’s regime. Images released by the family showed Marcos Jr visiting the home of his mother, who had displayed Picasso’s Femme Couche VI (Reclining Woman VI),
