Sri Lanka began a wildlife census on Saturday to count monkeys, peacocks and giant squirrels, aiming to manage their populations as farmers complain of agricultural losses.
Agriculture accounts for 8% of the country's economy and employs 8.1 million people, government data showed.
Sri Lanka is the fourth-largest coconut products exporter globally and produces about 3 billion cashew and other nuts annually, according to the Exports Development Board (EDB).
But coconut production, along with vegetable and fruit cultivation, has been hit due to crop destruction by monkeys, peacocks and giant squirrels, a top government official said.
"The problem has become so bad people are giving up farming. We are losing about 20% of total agricultural production. It is estimated that 90 million coconuts are lost every year," Namal Karunaratne, Deputy Minister of Agriculture and Livestock, told Reuters.
"The census is the first step to understanding the density of these animals in farming areas so we can formulate proper policies to manage them."
The census comes after an incident in February when a monkey caused a nationwide blackout and power cuts lasting for three days.
Edirisinghe Arachchilage Gnanasena, a 72-year-old farmer, counted 45 monkeys, six giant squirrels and nine peacocks, in the five minutes allocated for the census. His eight-acre plot of farmland in Dambulla, a city in central Sri Lanka, has been struggling with crop losses for years.
With an air gun across his shoulder and lead pellets in a plastic bag, Gnanasena spends hours patrolling the neat rows of coconut, mango and banana plants he has carefully grown.
But tribes of monkeys still strip trees of hundreds of coconuts and pick mangoes, while peacocks swallow long beans whole, Gnanasena said.
"Monkeys are used to the air gun, so I light firecrackers to scare them off. But they always come back."
Farmers attribute the rising numbers of monkeys, peacocks, porcupines and wild boars in the area to habitat loss.
"I hope this census leads to long-term solutions. That is what we want," he added.
"This is not the fault of the animals. It is the fault of the humans."

In a northern Tunisian olive grove, Yassine Khelifi's small workshop hums as a large machine turns olive waste into a valuable energy source in a country heavily reliant on imported fuel.

Holding a handful of compacted olive residue -- a thick paste left over from oil extraction -- Khelifi said: "This is what we need today. How can we turn something worthless into wealth?"

For generations, rural households in Tunisia have burned olive waste for cooking and heating, or used it as animal feed.

The International Olive Council estimated Tunisia will be the world's third-largest olive oil producer in 2024-2025, with an expected yield of 340,000 tons.

The waste generated by the oil extraction is staggering.

Khelifi, an engineer who grew up in a family of farmers, founded Bioheat in 2022 to tackle the issue. He recalled watching workers in olive mills use the olive residue as fuel.

"I always wondered how this material could burn for so long without going out," he said. "That's when I asked myself: 'Why not turn it into energy?'"

Beyond profit, Khelifi hopes his startup helps "reducing the use of firewood as the country faces deforestation and climate change".

At his workshop, employees transport truckloads of olive waste, stacking it high before feeding it into the processing machines.

The material is then compacted into cylindrical briquettes and left to dry for a month under the sun and in greenhouses before its packaging and sale.

- The soul of olives -

Khelifi began developing his idea in 2018 after he travelled across Europe searching for a machine to turn the olive paste into long-burning fuel.

Unable to find the right technology, he returned to Tunisia and spent four years experimenting with various motors and mechanical parts.

By 2021, he had developed a machine that produced briquettes with just eight-percent moisture.

He said this amount significantly reduces carbon emissions compared to firewood, which requires months of drying and often retains more than double the amount of moisture.

Bioheat found a market among Tunisian restaurants, guesthouses, and schools in underdeveloped regions, where winter temperatures at times drop below freezing.

But the majority of its production -- about 60 percent -- is set for exports to France and Canada, Khelifi said.

The company now employs 10 people and is targeting production of 600 tons of briquettes in 2025, he added.

Selim Sahli, 40, who runs a guesthouse, said he replaced traditional firewood with Khelifi's briquettes for heating and cooking.

"It's an eco-friendly and cost-effective alternative," he said. "It's clean, easy to use, and has reduced my heating costs by a third."

Mohamed Harrar, the owner of a pizza shop on the outskirts of Tunis, praised the briquettes for reducing smoke emissions, which he said previously irritated his neighbors.

"Besides, this waste carries the soul of Tunisian olives and gives the pizza a special flavor," he added.

- 'Protect the environment' -

Given Tunisia's significant olive oil production, waste byproducts pose both a challenge and an opportunity.

Noureddine Nasr, an agricultural and rural development expert, said around 600,000 tons of olive waste is produced annually.

"Harnessing this waste can protect the environment, create jobs, and generate wealth," he said.

Nasr believes repurposing olive waste could also help alleviate Tunisia's heavy dependence on imported fuel.

The country imports more than 60 percent of its energy needs, a reliance that widens its trade deficit and strains government subsidies, according to a 2023 World Bank report.

Fuel and gas shortages are common during winter, particularly in Tunisia's northwestern provinces, where households struggle to keep warm.

Redirecting agricultural waste into alternative energy sources could ease this burden.

Yet for entrepreneurs like Khelifi, launching a startup in Tunisia is fraught with challenges.

"The biggest hurdle was funding," he said, lamenting high-interest bank loans. "It felt like walking on a road full of potholes."

But now his goal is "to leave my mark as a key player in Tunisia's transition to clean energy," he added. "And hopefully, the world's, too."
