HELSINKI (Xinhua) — With a striking charging plug pattern on its side, the blue-and-white bus runs quietly, making almost zero noise. Looking carefully, one may spot the Chinese logos on the car glass.

Since August this year, residents in the capital region of Finland have often encountered such new “guys” when they travel by bus.

Being the first batch of pure electric buses in operation in Finland, the 33 buses produced by China’s Zhengzhou Yutong Bus Co. Ltd have met the requirements of Finnish authorities, participants in a media visit held in Helsinki on Monday were told.

The buses were introduced to Finland by Pohjolan Liikenne, one of Finland’s largest public transport operators.

“China is very advanced in the development and production of electric buses. Our partner Yutong is the world’s largest manufacturer of electric buses,” Heikki Alanko, managing director of Pohjolan Liikenne, told journalists.

“The battery of the electric bus produced by Yutong has good performance, large storage capacity and fast charging speed. According to our estimation, after full charge, it can support at least 200 kilometers of driving even under harsh conditions,” said Alanko.

“Our drivers gave pretty good feedback on driving Yutong pure electric buses. The passengers also praised them for the comfort and low noise,” Alanko said. “We are very satisfied.”

According to Alanko, more than a year ago, the Helsinki Region Transportation Authority, which is responsible for maintaining the public transportation network of nine cities in the capital area, tendered the first batch of pure electric buses. Yutong’s products were selected by Pohjolan Liikenne, one of the bidders, for their outstanding quality, and finally got recognized by the government.

“The government and the Helsinki Regional Transportation Authority have strict control over the quality of public transport vehicles. Pure electric buses by Yutong met our requirements in terms of model size, comfort, energy consumption, safety and follow-up services,” Johanna Nyberg, head of city traffic of Espoo in the Helsinki region, said.

Pure electric buses produced in China will also play an important role in helping Finland save energy, reduce emissions and promote green travel.

According to Nyberg, several cities in the Helsinki region, including Espoo, plan to increase the proportion of zero-carbon public transport to 30 percent within five years, and reach 100 percent zero-carbon emissions in public transport system by 2030.

The arrival of the pure electric buses “will optimize our bus system,” marking an important step towards green travel in cities, Nyberg said.

Ma Kai, Nordic market project manager at Yutong, told Xinhua that in light of the long, cold and snowy winters in Finland, Pohjolan Liikenne was very concerned about the performance of the buses.

Representatives of the Finnish bus operator “came to Harbin (the capital of Heilogjiang, China’s northernmost province), which has a similar winter climate as Finland, for testing our products, and finally were convinced by the quality,” said Ma.

Ma said Yutong representatives had visited Finland many times before winning the contract with Pohjolan Liikenne.

“Yutong attaches great importance to follow-up services and sets up commissioners for overseas customers to ensure vehicle operation and provides skills training,” said Ma.

Yutong is a Chinese bus manufacturer that has an excellent track record in the new energy bus industry. The publicity department of Yutong told Xinhua that as of July 2019, the company had sold 120,000 new energy buses worldwide, including more than 8,000 in Europe. In 2018, its large and medium-sized passenger vehicles had a global market share of 13 percent.

“The development of our new energy bus business is largely due to China’s vigorous promotion of new energy vehicle research and development (R&D) and production in the past few years. The forward-looking policies have enabled us to touch the pulse of the industry, accumulate a wealth of experience and get our technical strength enhanced,” Ma said

ALONG THE VJOSA RIVER (AP) — Under a broad plane tree near Albania’s border with Greece, Jorgji Ilia fills a battered flask from one of the Vjosa River’s many springs.

“There is nothing else better than the river,” the retired schoolteacher says. “The Vjosa gives beauty to our village.”

The Vjosa is temperamental and fickle, changing from translucent cobalt blue to sludge brown to emerald green, from a steady flow to a raging torrent. Nothing holds it back for more than 270 kilometers (170 miles) in its course through the forest-covered slopes of Greece’s Pindus mountains to Albania’s Adriatic coast.

This is one of Europe’s last wild rivers. But for how long?

Albania’s government has set in motion plans to dam the Vjosa and its tributaries to generate much-needed electricity for one of Europe’s poorest countries, with the intent to build eight dams along the main river.

It’s part of a world hydropower boom, mainly in Southeast Asia, South America, Africa and less developed parts of Europe. In the Balkans alone, about 2,800 projects to tame rivers are underway or planned — a “dam tsunami,” says Olsi Nika of EcoAlbania, a nonprofit that opposes the projects.

Some tout hydropower as a reliable, cheap and renewable energy source that helps curb dependence on planet-warming fossil fuels like coal, oil and natural gas. The Intergovernmental Panel on Climate Change says it has “significant potential” to further reduce carbon emissions.

But some recent studies question hydropower’s value in the fight against global warming. Critics such as EcoAlbania say the benefits of hydropower are overstated — and outweighed by the harm dams can do.

Rivers are a crucial part of the global water cycle. They act as nature’s arteries, carrying energy and nutrients across vast landscapes, providing water for drinking, food production and industry. They’re a means of transportation for people and goods, and a haven for boaters and anglers. Rivers are home to a diversity of fish — including tiny minnows, trout and salmon — and provide shelter and food for birds and mammals.

But dams interrupt their flow, and the life in and around them. While installing fish ladders and widening tunnels to bypass dams helps some species, it hasn’t worked in places like the Amazon, says Julian Olden, a University of Washington ecologist who has studied the impacts of dams in Brazil, Australia and the U.S.

Dams block the natural flow of water and sediment, and can cause harmful temperatures swings. They also can change the chemistry of the water and cause toxic algae to grow.

“Once dams go in, there’s almost no going back,” Olden says. “You starve a river of water. It’s unsurprising that its inhabitants are likely to disappear.”

Those who live along the riverbank or rely on the waterway for their livelihood fear dams could kill the Vjosa as they know it. Its fragile ecosystem will be irreversibly altered, and many residents will lose their land and homes.

“It’s like humans,” says Elton Pashollari, a river rafting guide whose clients are increasingly attracted by the Vjosa’s wildness. “What happens if one of your arteries, it stops, blood doesn’t circulate anymore? It’s the same thing with the Vjosa.”

From Ilia’s plane tree near the Greek border, the Vjosa flows north through narrow gorges before passing by the town of Tepelene, growing more languid and broadening into wide gravel banks, its flow splitting into strands — what scientists call a braided river.

This characteristic is typical of wild rivers and is critical to the local ecosystem. It creates diverse habitats and allows sediment to flow, fertilizing the floodplains and rejuvenating the riverbed.

It is here that the Vjosa reveals another side of its wild nature. After seasonal floods, the river can change course, its braids re-forming along the deep gravel that serves as a filter and self-purification system. It skips from left to right to the center, across an area around 1.5 kilometers (1 mile) wide.

“A natural river is a dynamic river … a living river,” says Nika of EcoAlbania. “It’s living day by day and it changes its face. After each flood, you could never see the same scenery.”

The river’s ability to clean itself has proved crucial in a country where waste management is often rudimentary. For years, people have dumped trash in gullies that washed into the river, leaving trails of plastic and cloth clinging to tree branches. Some towns still dump raw sewage, but the river’s self-cleansing means that the overall water quality is passable.

About 25 kilometers (16 miles) northwest of Tepelene, the riverbed narrows into another tight, steep gorge teeming with life, where birds swoop from trees anchored precariously in the cliff-face. Just beyond that comes the first sign of how dramatically a dam would affect the river and the life connected to it.

Emerging from the canyon, it like a strip mine. This is Kalivac, one of the proposed dam sites. An Italian company was awarded a contract in the late 1990s. Construction began, but never finished, plagued with delays and financial woes. It now lies derelict with guards stationed to prevent looting.

Half the hill on one side has been dug away, creating giant steps into the rock. Vehicles sit abandoned, a digging machine sunken into the ground, branches and debris clinging to its frame.

Now, the government has awarded a new contract for the site to a Turkish company.

For Benedikt Baeumler, a German advertising executive kayaking the length of the river, the sight was a shock.

“I felt like there’s all this wonderful nature, and then suddenly to see these stairs, like the Egyptian pyramids,” he says.

A few days earlier and several miles upriver, the 43-year-old had been ambivalent about the hydropower projects, noting his own country had also dammed its rivers.

But what he saw at the Kalivac site changed his mind.

“It was really unbelievable what they did to nature, removing entire parts of the mountain,” he said, setting up camp on a sandbar back in June. “I hope this dam is never built.”

Many locals agree. Dozens of residents from the village of Kute, further downriver, joined nonprofits to file what was Albania’s first environmental lawsuit against the construction of a dam in the Pocem gorge, a short distance downriver from Kalivac. They won in 2017, but the government has appealed.

The victory, while significant, was just one battle. A week later, the government issued the Kalivac contract. EcoAlbania plans to fight that project, too.

Ecologically, there is a lot at stake.

A 2018 study led by University of Vienna’s Fritz Schiemer found the Vjosa was incredibly diverse. The team logged more than 90 types of aquatic invertebrates in the places where dams are planned, plus hundreds of fish, amphibian and reptile species, some endangered and others endemic to the Balkans.

But “the majority of the specific biodiversity will disappear in the case of the planned dam constructions,” they warned.

Dams can unravel food chains by reducing populations of insects that feed fish and by limiting spawning, which in turn leaves less prey for fish-eating birds and mammals. But the most well-known problem with building dams is that they block the paths of fish trying to migrate upstream to spawn. The U.S. Atlantic salmon population has plummeted, according to the National Oceanic and Atmospheric Administration, in great part due to dams.

As pressure to build dams intensifies in less developed countries, the opposite is happening in the U.S. and western Europe, where there’s a movement to tear down dams considered obsolete and environmentally destructive.

More than 1,600 have been dismantled in the U.S., most within the past 30 years, according to the advocacy group American Rivers. In Europe, the largest-ever removal began this year in France, where two dams are being torn down on Normandy’s Selune River.

With so few wild rivers left around the globe, the Vjosa also is a valuable resource for studying river behavior.

“Science is only at the beginning of understanding how biodiversity in river networks is structured and maintained,” says researcher Gabriel Singer of the Leibniz-Institute in Germany. “The Vjosa is a unique system.”

For Shyqyri Seiti, it’s much more personal.

The 65-year-old boatman has been transporting locals, goods and livestock across the river for about a quarter century. The construction of the Kalivac dam would spell disaster for him. Many of the fields and some of the houses in his nearby village of Ane Vjose would be lost.

“For me, the river is everything,” he says. “Someone will benefit from the construction of the dam, but it will flood everyone in the area. … What if they were in our place, how would they feel to lose everything?”

His love for the river runs deep: It feeds his family by providing work and fish to eat and sell. He taught his five children to swim here. Every morning, he runs down to the river just to take in the view.

Seiti has protested against the plans, but some of his neighbors disagree. The mayor, Metat Shehu, insists the community “has no interest” in the matter.

“The Vjosa is polluted. The plants and creatures of Vjosa have vanished,” Shehu says while tending his goats. The biggest issue, he adds, is that villagers are being offered too little to give up their land. He hopes the dam will bring investment to the area.

About 10 kilometers (6 miles) downriver of Ane Vjose lies the village of Kute, on a hill overlooking the Vjosa as it snakes its way north to the sea. Kute residents joined the lawsuit against the Pocem dam that would flood their fields, some houses and, crucially for many, a cemetery. Relieved by their victory, they now wait anxiously for the outcome of the government’s appeal.

There are some signs in their favor. In August, the government announced it was canceling a project in central Albania’s Holta Canyon near the town of Gramsh, and would tear down part of a dam that’s already built. The Infrastructure and Energy Ministry said in a statement the decision came after discussions with residents and an environmental review. Energy ministry officials rejected multiple interview requests to discuss the Vjosa River and the country’s hydropower plans.

Could the Vjosa projects also be stopped?

Jonus Jonuzi, a 70-year-old farmer who grew up along the river, still has hope.

He raised his children here and now watches his grandchildren play in its waters. Before dawn each day, he crosses a bridge over a narrow gorge to tend to his goats before his son drives them to drink from a local spring, where the water emerges cold and crystal clear.

“Everything I have, I have because of the river,” he says. “Albania needs electrical energy. But not by creating one thing and destroying another. Why do such damage that will be irreparable for life, that future generations will blame us for what we’ve done?”
