Solar-powered plane leaves Japan bound for Hawaii

A solar-powered plane took off from Japan early Monday to attempt a five-day flight over open water to Hawaii, the eighth leg of its bid to fly around the world without fuel.

Its long wings lighting up the night sky, the Solar Impulse 2 departed at 3:03 a.m. after an unscheduled, month-long stop in Japan because of unfavorable weather.

The flight to Hawaii, by far the longest of the journey so far, is risky because there are few if any places to land in an emergency.

Swiss pilot Andre Borschberg is flying solo. The plane, which started in Abu Dhabi on March 9, is powered by more than 17,000 solar cells on its wings that recharge its batteries. From Hawaii, it is to continue on to Phoenix, then hopscotch across the United States and the Atlantic to Europe, before returning to Abu Dhabi.

Borschberg originally left Nanjing, China, for Hawaii on May 31, but diverted to an airport in Nagoya in central Japan on June 1 because a cold front threatened to block his way. After a wing repair, he and team members waited in Nagoya for the right conditions to depart.

The project is meant to demonstrate the potential of improved energy efficiency and clean power, though solar-powered air travel is not yet commercially practical.

Solar Impulse 2 is dependent on the right weather conditions, and organizers waited about nine hours after takeoff for the plane to pass what they called “the point of no return” before officially announcing that it was aloft.

Cameroon fishing industry and tourism battered by extreme weather

As storms wreak havoc on a key industry, prompting visitors to stay away, fishermen in Kribi fear not only the sea but also the future.

For more than 15 years, Raoul Meno has been fishing the waters off the coastal town of Kribi in southern Cameroon. Occasionally, he has had to face down storms and high seas to bring home a catch to support his family. But now, he is scared.

“I go for days without going to sea for my catch because of the frightening weather,” Meno says.

A bout of persistent heavy rains and surging tides this year has made fishing in Kribi increasingly difficult and left fishermen like him struggling to make a living.

“This is the first time we are witnessing such aggressive weather,” he says. “I wonder what is really going wrong with nature.”

As Kribi struggles to cope with hard times in its fishing industry, the weather is also hitting tourism, simultaneously threatening to destroy the town’s two main sources of income.

With its sandy beach, seaside resort and beautiful lowland scenery, Kribi contributes significantly to Cameroon’s tourism industry. It is the country’s second most popular destination after the Waza and Bouba N’Djida parks in the north.

But statistics from Kribi’s city council show that tourist visits to the region in 2014 dropped by more than 60% compared with the year before.

According to Eric Serge Epoune, a spokesman for Cameroon’s ministry of tourism, the loss of income from just one coastal town is having a catastrophic impact when combined with other pressures on the nation’s economy. “At a time when the Boko Haram scare has ground to a halt tourism in Cameroon’s far north, a harsh climate is preventing our second most popular tourist zone from pulling in visitors,” he says. “Tourism and crafts are at a dead end, and let’s not even talk about the hotel business – it is virtually nonexistent.”

Erratic rains and high tides have played havoc with Kribi’s hopes of giving the city a facelift – and an economic boost. According to city council authorities, rains have caused major delays to the start of construction on a new urban development master plan, due to be completed by 2025.

The revitalisation was scheduled to begin once building was finished on a new deep-sea port and gas plant, but Cameroon’s increasingly extreme weather has slowed down construction on those projects.

Environmental experts in Yaoundé, the capital, say all the new construction might have made the area more vulnerable to erratic rains and sea surges as a result of worsening deforestation.

Most of the forests in Cameroon’s south have been sacrificed for development projects, they say, including huge tracts of land around Kribi that have been cleared for the new port and gas plant.

Experts say mangrove forests along the coast are crucial to protecting the shoreline and mitigating damage from storms and high seas. “Even if we negate all benefits of mangroves as forests, their value as the ‘shoreline protector’ should be enough to convince us to conserve them,” says Youssoufa Bele, one of the authors of a 2014 report about the importance of mangroves by the Centre for International Forestry Research.

The trees’ roots spread across large areas, soaking up water and holding soil and sediment, he says.

Samuel Nguiffo of the Centre for Environment and Development in Cameroon, an NGO that deals with forest and land issues, says the first step to protecting the port and gas plant from extreme weather could be through major reforestation efforts.

“A tree-planting initiative by the Kribi local council with support from the government is necessary along the entire coastline,” he says. “This would restore the dune ecosystem and reduce the impact of rising sea levels, as well as minimise any future storm surges that could pose a potential danger to the port’s infrastructure.”

For now, Kribi is still grappling with the harsh weather that has undercut its economy. While fishermen have become afraid of the sea, the women who buy, smoke and sell fish also are struggling to stay in business.

Many have been left with no alternative but to drive to Douala, Cameroon’s commercial capital, about 250km from Kribi, to buy imported fish and sell it on at a higher price.

“The selling of fresh and smoked fish is my life,” said Helen Taku, a fish vendor in Kribi. “I feed my family and send my children to school on income from the fish trade. I really fear for the future.”
