Vietnamese push back on Facebook to save Hanoi's trees

Vietnamese are often wary of talking about politics for fear of running afoul of their communist government - but the garden gloves came off in a fight over Hanoi's beloved trees.

It's sometimes called the "Paris of Asia" on account of its wide boulevards and well-preserved French-influenced architecture. Hanoians are justifiably proud of their city's beauty - which is part of the reason why a government plan to axe hundreds of the city's trees resulted in a huge push back on Facebook.

A Facebook page set up to save the trees quickly garnered more than 50,000 fans. And following a massive outpouring of opposition by celebrities and ordinary people, the government reversed its decision and promised to replace trees that had already been felled.

But the victory was about more than just foliage. Speaking out against the government can earn Vietnamese a jail sentence, and it seems the outpouring over the capital's tree population pointed to a more general sentiment inside the country.

"To be precise it's not only this tree chopping but virtually every policy of the government is being complained about," said one Facebook user. "Many things are short-termish and unreasonable that are not to the people's liking and people have lost trust [in the government]."

Hung Nguyen of BBC Vietnamese says the nature of the campaign - or rather, the fact it was a nature campaign - allowed Hanoians to question their government.

Facebook users including model Ha Anh Vu posted pictures of themselves enjoying Hanoi's parks and trees.

"This is a rare example of civil society in Vietnam," Nguyen says. "Challenging the government or party is still something rare in Vietnam and can land people in jail quite easily. But this issue appears to be non-                                                                                            political which is why it got momentum on Facebook."

'Water man of India' Rajendra Singh bags top prize

An award known as "the Nobel Prize for water" has been given to an Indian campaigner who has brought water to 1,000 villages.

The judges of the Stockholm Water Prize say his methods have also prevented floods, restored soil and rivers, and brought back wildlife.

The prize-winner, Rajendra Singh, is dubbed "the Water Man of India"The judges say his technique is cheap, simple, and that his ideas should be followed worldwide.Mr Singh uses a modern version of the ancient Indian technique of rainwater harvesting.It involves building low-level banks of earth to hold back the flow of water in the wet season and allow water to seep into the ground for future use.

Mr Singh discovered the vital need for solutions to disappearing water while working in a rural village

He first trained as a medic, but when he took up a post in a rural village in arid Rajasthan he was told the greatest need was not health care but drinking water.

Groundwater had been sucked dry by farmers, and as water disappeared, crops failed, rivers, forests and wildlife disappeared and people left for the towns.

"When we started our work, we were only looking at the drinking water crisis and how to solve that," Mr Singh said.

"Today our aim is higher. This is the century of exploitation, pollution and encroachment. To stop all this, to convert the war on water into peace, that is my life's goal."

The Stockholm International Water Institute, which presented the prize, said his lessons were essential as climate change alters weather patterns round the world.

The methods are based on an ancient Indian technique

Its director, Torgny Holmgren, said: "In a world where demand for freshwater is booming, we will face a severe water crisis within decades if we do not learn how to better take care of our water. Mr Singh is a beacon of hope."

In its citation, the judges say: "Today's water problems cannot be solved by science or technology alone. They are human problems of governance, policy, leadership, and social resilience.

"Rajendra Singh's life work has been in building social capacity to solve local water problems through participatory action, empowerment of women, linking indigenous know-how with modern scientific and technical approaches and upending traditional patterns of development and resource use."

The award was applauded by Katherine Pygott, a leading UK water engineer who has drawn on Mr Singh's work to help prevent flooding in the UK.

Spain: Rare Iberian lynx tracked in Madrid region

The critically endangered Iberian lynx has returned to the Madrid region of Spain for the first time in decades, it's reported.

Conservation efforts have successfully raised the Iberian lynx population to more than 300, but many have been killed on Spanish roads

It's more than 40 years since the species has set foot in the region, but now one has been tracked near a town just 50km (31 miles) south of the Spanish capital, El Pais reports. The male lynx, called Kentaro, was born in captivity and released along with seven others in Toledo in late 2014. Since then he's been quite the adventurer, travelling about 100km and crossing several motorways, according to conservationists. "Not all lynxes are this adventurous. They tend to stay close to where they were born," says Ramon Perez de Ayala from the World Wildlife Fund (WWF). But Kentaro has "packed his bags and set off on his travels," he says. "We've been lucky because the roads he has crossed are well fenced and he hasn't been run over. He will have followed the fences until he found a bridge, and then crossed over there." Kentaro wears a GPS collar which allows conservationists to track his whereabouts.

The Iberian Lynx is the world's most endangered feline, and the only breeding populations are both in southern Spain. Traffic is one of the the biggest dangers for the species - according to El Pais, at least 21 lynxes were hit and killed on Spanish roads in 2014, and 14 died the year before. The WWF wants Spain's regional governments to put in place special measures which would help protect lynxes, including fencing off roads and motorways.

Global CO2 emissions 'stalled' in 2014

 The growth in global carbon emissions stalled last year, according to data from the International Energy Agency.

 

China is now by far the world's biggest investor in renewable energy, far outstripping the US

 

It marks the first time in 40 years that annual CO2 emissions growth has remained stable, in the absence of a major economic crisis, the agency said.

Annual global emissions remained at 32 gigatonnes in 2014, unchanged from the previous year.

But the IEA warned that while the results were "encouraging", this was "no time for complacency".

"This is both a very welcome surprise and a significant one," said IEA Chief Economist Fatih Birol.

 

It provides much-needed momentum to negotiators preparing to forge a global climate deal in Paris in December: for the first time, greenhouse gas emissions are decoupling from economic growth."

And IEA Executive Director Maria van der Hoeven said while the data was "encouraging", this was "no time for complacency" and "certainly not the time to use this positive news as an excuse to stall further action".

Changing patterns

Analysts attribute the slowdown in emissions to changing patterns of energy consumption in China and OECD countries.

Prof Corinne Le Quere, of the Tyndall Centre for Climate Change Research at the University of East Anglia, said: "An important factor could be that China's coal consumption fell in 2014, driven by their efforts to fight pollution, use energy more efficiently and deploy renewables.

"Efforts to reduce emissions elsewhere will have played a role, but there are also more random factors such as the weather and the relative price of oil, coal and gas."

The IEA said changing patterns of energy use in China and in OECD countries, including the shift towards more renewable energy, was having the desired effect of decoupling economic growth from greenhouse emissions.

The Paris-based organisation said that in the 40 years it had been collecting data on carbon dioxide emissions, annual emissions had stalled or fallen only three other times, which were all associated with global downturns:

• after the US recession in the early 1980s
• in 1992 after the collapse of the former Soviet Union
• in 2009 during the global financial crisis

Greenhouse gas emissions may finally be decoupling from economic growth

Full details of the IEA report will be released in June, ahead of UN negotiations to sign a new international climate change agreement at talks in Paris in December.

Countries are aiming to reach agreement on a deal that will come into force from 2020.

The aim is to limit the increase of the average global surface temperature to no more than 2C (3.6F) compared with pre-industrial levels, to avoid "dangerous" climate change.

Energy and Climate Change Secretary Ed Davey said the figures showed that green growth is achievable not just for Britain but for the world.

He added: "However we cannot be complacent - we need to dramatically cut emissions, not just stop their growth.

"Getting a new global climate deal is absolutely vital, and the year ahead is going to be of critical importance. "

Solar Impulse: Oman to India journey sets new record

Solar Impulse, the fuel-free aeroplane, has successfully completed the second leg of its historic attempt to fly around the world.

Project chairman, Bertrand Piccard, piloted the vehicle from Muscat in Oman to Ahmedabad in India, crossing the Arabian Sea in the process.

Tuesday's journey took just over 15 hours.

The distance covered - 1,468km - set a new world record for a flight in a piloted solar-powered plane.

The vehicle has another 10 legs ahead of it over the course of the next five months.

Included in that itinerary will be demanding stretches when the craft has to fly over the Pacific and Atlantic oceans.

Piccard is sharing the flying duties with project partner and CEO, Andre Borschberg, who made Monday's inaugural trip from Abu Dhabi to Muscat.

Solar Impulse arrived in Ahmedabad in darkness, its wings illuminated by LEDs, and its propellers driven by the energy stored in its batteries.

The plane had left Muscat at 06.35 (02:35 GMT) and put its wheels down at Sardar Vallabhbhai Patel International Airport at 23.25 local time (17:55 GMT).

Preparations are already under way for the next leg to Varanasi in northeast India, although mission planners say that will not be for another four days, at least.

The time will be spent carrying a campaigning message on the topic ofclean technologies to the local Ahmedabad people, and the wider Indian population.

Solar Impulse heads out over the Arabian Sea

The Solar Impulse project has already set plenty of other world records for solar-powered flight, including making a high-profile transit of the US in 2013.

But the round-the-world venture is altogether more dramatic and daunting, and has required the construction of an even bigger plane than the prototype, Solar Impulse-1.

This new model has a wingspan of 72m, which is wider than a 747 jumbo jet. And yet, it weighs only 2.3 tonnes.Its light weight will be critical to its success.

So, too, will the performance of the 17,000 solar cells that line the top of the wings, and the energy-dense lithium-ion batteries it will use to sustain night-time flying.Operating through darkness will be particularly important when the men have to cross the Pacific and the Atlantic.

The slow speed of their prop-driven plane means these legs will take several days and nights of non-stop flying to complete.Piccard and Borschberg - they take it in turns to fly solo - will have to stay alert for nearly all of the time they are airborne.

They will be permitted only catnaps of up to 20 mins - in the same way a single-handed, round-the-world yachtsman would catch small periods of sleep.They will also have to endure the physical discomfort of being confined in a cockpit that measures just 3.8 cubic metres in volume - not a lot bigger than a public telephone box.

The Solar Impulse venture recalls other great circumnavigation feats in aviation - albeit fuelled ones.In 1986, the Voyager aircraft became the first to fly around the world without stopping or refuelling.

Piloted by Dick Rutan and Jeana Yeager, the propeller-driven vehicle took nine days to complete its journey.Then, in 2005, this time was beaten by the Virgin Atlantic GlobalFlyer, which was solo-piloted by Steve Fossett. A jet-powered plane, GlobalFlyer completed its non-stop circumnavigation in just under three days.
