Yemen’s Ancient Honey Production a Victim of War, Climate Change

For Yemeni beekeeper Mohammed Saif, honey production used to be a lucrative business but years of war and climate change have taken the buzz out of the family hives.

The business, handed down from father to son, "is slowly disappearing", Saif told AFP. "The bees are being hit by strange phenomenons. Is it due to climate change or the effects of war? We really don't know."

Yemen, one of the world's most impoverished countries, has been gripped by a deadly conflict since 2014.

In the southwestern region of Taiz, Saif recently took stock of his hives in a rugged valley surrounded by mountains.

Before the war, Saif said, the family managed 300 hives, now only 80 are left.

Experts consider Yemeni honey some of the best in the world, including the prized Royal Sidr known for its therapeutic properties.

The United Nations says honey plays a "vital role" in Yemen's economy, with 100,000 households dependent on it for their livelihoods.

- Bee ecosystems battered -

But "enormous losses have been inflicted on the industry since the outbreak of the conflict", the International Committee of the Red Cross said in a report in June.

"Armed conflict and climate change are threatening the continuity of a 3,000-year-old practice," the ICRC said.

"Successive waves of displacement to flee violence, the impact of weapon contamination on production areas, and the growing impact of climate change are pushing thousands of beekeepers into precarity, significantly reducing production."

Saif knows it all too well.

"Last year in our village a missile struck a beekeeper's hives. He lost everything," he said.

"The war has had a very bad impact on us. The fighters have targeted many zones where bees are found," he added.

The ICRC's Bashir Omar said the conflict had limited the ability of beekeepers to freely roam the land whenever flowers were in bloom to collect the honey.

Landmines and active front lines are among the challenges they face.

"To make matters worse, Yemen, like many conflict-affected countries, is disproportionately affected by climate change," the ICRC report noted.

"Temperature rises in recent years, combined with severe alterations caused to the environment, are disturbing the bees' ecosystem which is impacting the pollination process," it said.

"With water tables falling and increased desertification, areas previously engaged in agricultural activities and beekeeping no longer sustain these livelihoods."

The ICRC is providing financial support and training this year to beekeepers, after a similar initiative in 2021 that helped nearly 4,000 of them.

Nabil al-Hakim, who sells Yemen's celebrated yellow nectar in Taiz shops, also recalled the golden days before the conflict ravaged his country.

"Before the war we could make a good living by selling honey... but honey has become rare and customers can no longer afford it," he said.

"Before, I used to sell up to 25 five-liter jars a month. Now I can't even sell one."

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
