Plan B: Pakistani beekeepers widen pursuit of flowers

Under a dry, smoggy sky, a beekeeper in Pakistan's Punjab province carefully loads boxes filled with tens of thousands of bees onto the back of a truck.

Together they will travel 500 kilometres (around 300 miles) in an increasingly desperate chase to find flowering plants, clean air and moderate temperatures for honey production as climate change and pollution threaten the industry.

"We move the boxes according to where the weather is good and the flowers bloom," Malik Hussain Khan told AFP, standing in a field of orange trees whose blossoms arrived weeks late in February and lasted only for a few weeks.

Pakistan's beekeepers typically move seasonally to spare their charges stifling heat or freezing cold.

Summers are spent in northwestern Khyber-Pakhtunkhwa province, and winters in central Punjab province.

But weather patterns made unpredictable by climate change -- coupled with some of the worst pollution in the world -- mean beekeepers must move more frequently and travel further.

This winter was marked by soaring, hazardous smog levels that the government declared a national disaster. Research has found air pollution can make it harder for bees to locate flowers.

Diminished rainfall, meanwhile, failed to clear the choking air and triggered drought warnings for farmers.

"Almost half of my bees died when the smog and fog hit this winter because they could not fly. There was hardly any rain," said Khan, who moved his bees as frequently as every few weeks in January and February.

The bees of Pakistan's 27,000 beekeepers once had diverse foliage fed by reliable rainfall, offering a rich source of nectar.

Their honey is used in local flu remedies, drizzled over sweets, and given as gifts.

Since 2022 however, Pakistan's honey production has dropped 15 percent, according to the government's Honey Bee Research Institute (HBRI) in the capital Islamabad.

"Heavy rainfall and hail storms can destroy the flowers, and erratic rainfall and high temperatures during the winter flowering season can stop them from blooming," said Muhammad Khalid, a researcher at the institute.

"When the flowers disappear, the bee population declines because they cannot find nectar, resulting in reduced honey production."

Bees are threatened globally by changing weather patterns, intensive farming practices, land-use change, and pesticides.

Their loss threatens not just the honey trade, but food security in general, with a third of the world's food production dependent on bee pollination, according to the Food and Agriculture Organisation.

Pakistan's bees once produced 22 varieties of honey, but that has plummeted to 11 as flowering seasons shorten. Three of the country's four honey bee species are endangered.

"The places that used to be green for our bees to fly 30 years ago, no longer are," says 52-year-old honey trader Sherzaman Momaan, who speaks with tenderness about his winged charges.

"We didn't move around then as much as we do now."

His hives were almost entirely wiped out by 2010 floods in Khyber Pakhtunkhwa, but he believes deforestation is the most significant long-term change and threat.

Yousaf Khan and his brother, based in Islamabad, have been producing honey for 30 years, moving short distances around neighbouring Punjab to catch the best blooms. "Now, we go as far as Sindh (province) for warmer temperatures and to escape extreme weather conditions," Khan told AFP, referring to areas up to 1,000 kilometres (600 miles) away.

"Bees are like babies, they need a good environment, good surroundings, and proper food to survive."

Moving the bees comes with its own risks.

"If the weather is very hot, or if the distance is too long, there is a chance that some bees could die. It has happened to my bees before," Khan explained.

On long trips, they must also be fed artificial food because they cannot produce honey while travelling.
