BAGHDAD (AFP) - Resurgent militants, ethnic land disputes or regular field burning?
Iraq's northern farmlands are on fire, but the area's complex patchwork of grievances has made it hard to identify the culprits.
Farmers in the country's breadbasket had been hoping for bumper wheat and barley harvests in May and June, following heavy winter rains.
Instead, many saw their hopes turned to ash.
The Iraqi fire service says that in a single month, 236 fires destroyed 5,183 hectares of farmland - the equivalent of more than 7,000 football pitches.
The blazes hit four northern provinces, all of which had been at least partly controlled by the Islamic State in Iraq and Syria (ISIS) militant group and have remained prey to the militants' sleeper cells.
ISIS has continued to carry out hit-and-run attacks despite losing its Iraqi foothold in late 2017 and its last Syrian enclave just a few months ago.
Indeed, the group was quick to claim responsibility for the fires.
In its weekly online magazine al-Naba, it said its fighters had destroyed "hundreds of hectares" owned by "apostates" in the provinces of Kirkuk, Nineveh, Salahaddin and Diyala.
Officials in those areas told AFP they believed ISIS was responsible for at least some of the fires.
"ISIS fighters set fire to the fields because the farmers refused to pay them zakat," said one police officer in Kirkuk, referring to a tax imposed under Islamic law.
"They came by motorcycle, started the fires and also planted explosives that would go off when residents or firefighters got there," he said.
The mines have killed at least five people and wounded 10 in Kirkuk province.
But experts are reluctant to blame all of the fires on ISIS.
The extreme heat of northern Iraq, where temperatures have been hitting 45 deg C, has created tinder-dry conditions in which a stray cigarette can easily set a field alight.
Farmers are also known to burn off vegetation in fields left fallow to make the soil more fertile for future seasons.
The longstanding tug-of-war over land in northern Iraq likely also plays a role, said security expert Hisham al-Hashemi.
"ISIS claimed dozens of fires, but the others were certainly the product of land disputes, most often among tribes," he said.
Kirkuk, whose status is disputed by federal government and autonomous Kurdish regional administration, has witnessed periodic violence between Arabs, Kurds and Turkmen.
So has Nineveh, which has seen 119 fires in recent weeks, 16 of them on Thursday (June 6) alone, according to its agricultural department chief Duraid Hekmat.
"There could be a variety of reasons - it could be deliberate or just an act of God, it could be negligence or personal disputes," he said.
Nineveh was among the provinces hardest hit by ISIS, which seized its capital Mosul as its headquarters in 2014 and slaughtered thousands of members of its Yazidi religious minority.
"We're facing a huge shortage of fire trucks. We have 50-55 vehicles but it's not enough for 1.5 million hectares," said Mr Zakaria Ahmad, deputy head of Nineveh's fire service.
HARVEST HOPES DASHED
The fires have been devastating for farmers banking on a good harvest to pay off their debts.
Around a third of Iraqis rely on agriculture for their livelihoods, with the government subsidising seeds and guaranteeing to buy part of the harvest.
Kirkuk's 200,000 hectares produce an average 650,000 tonnes every year, according to Mr Burhan Assi, who heads the provincial council's agricultural service.
"This year, thanks to the rains, we were expecting around four tonnes per hectare, compared to just two last year because of the drought," he said.
But most of that has been destroyed in fires he called "the biggest, most widespread we've ever seen".
Mr Raad Sami, who farms land in southern Kirkuk, lost 90 hectares of wheat to the fires, which he blamed on ISIS.
"We had been waiting for the end of the season to reap our harvest and sell it to pay back our debts," he said.
"Right now, the government needs to compensate us."
Mr Youssef Ahmad, a Turkmen farmer, is resigned to fate.
"Either it was ISIS, people who want to seize our land, or the result of a dispute between Baghdad and the Kurds," he said.
"All together, they successfully destroyed Iraq's economy and agriculture. Because of them, we're going to have to import wheat."
