Japan's Fukushima nuclear plant opened to reporters

Reporters have been allowed inside the Fukushima nuclear plant in Japan for the first time since it was crippled by an earthquake and tsunami in March.

The journalists toured the plant wearing full protective clothing.

A reporter from the Associated Press described seeing "twisted and overturned trucks, crumbling reactor buildings and piles of rubble virtually untouched since the wave struck".

Three reactors melted down after the tsunami wrecked their cooling systems.

The authorities have previously rejected requests by journalists to visit the plant, on the grounds that radiation levels were too high and it could hamper operations to tackle the crisis.

This tour was designed to show that the situation at the plant is gradually becoming more stable.

The reporters arrived at Fukushima on Friday and were shown a nearby football-training complex which is now being used as a base for the clean-up operation.

On Saturday they were shown around the Fukushima site itself and were able to take the first pictures inside the damaged plant.

The media tour was accompanied by the head of the Fukushima plant, Masao Yoshida, who described the dire conditions there following the tsunami.

"In the first week immediately after the accident I thought a few times, I'm going to die," he said.

However, he suggested that the situation there was now much better.

"I believe the plant is stabilised to the level that residents in surrounding communities can live without fear."

"But it's still very tough conditions for the recovery workers inside the complex," he added.

The government minister in charge of the clean-up operation, Goshi Hosono, was also there and made a speech to workers at the plant praising them for the progress being made.

"Every time I come back, I feel conditions have improved. This is due to your hard work," he said.

'Cold shutdown'

Large quantities of radioactive material leaked into the surrounding area following the disaster and much of the countryside around the plant is sealed-off.

The authorities are hoping to complete a "cold shutdown" of the damaged reactors by the end of the year. But it could take decades to completely decommission the plant.

Of the six reactors at Fukushima, four were badly damaged by the tsunami.

The nuclear fuel rods in reactors one, two and three melted down due to a failure of the cooling systems, causing damage to their containment structures.

There were also explosions caused by a build-up of hydrogen gas.

Completing the process of stabilising these reactors remains the main task at the plant, but the authorities have also been trying to tackle the accumulation of highly contaminated waste water in the reactor buildings.

'Ten years' to solve nature crisis, UN meeting hears

Nagoya, Japan

Delegates will consider adopting new set of targets for 2020 that aim to tackle biodiversity loss

The UN biodiversity convention meeting has opened with warnings that the ongoing loss of nature is hurting human societies as well as the natural world.

The two-week gathering aims to set new targets for conserving life on Earth.
Japan's Environment Minister Ryo Matsumoto said biodiversity loss would become irreversible unless curbed soon.

Much hope is being pinned on economic analyses showing the loss of species and ecosystems is costing the global economy trillions of dollars each year.
Ahmed Djoghlaf, executive secretary of the UN Convention on Biological Diversity (CBD), described the meeting in Nagoya, Japan, as a "defining moment" in the history of mankind.

"[Buddhist scholar] Daisetsu Teitaro Suzuki said 'the problem of nature is the problem of human life'. Today, unfortunately, human life is a problem for nature," he told delegates in his opening speech.

Referring to the target set at the UN World Summit in 2002, he said:
"Let's have the courage to look in the eyes of our children and admit that we have failed, individually and collectively, to fulfil the Johannesburg promise made by 110 heads of state to substantially reduce the rate of loss of biodiversity by 2010.
"Let us look in the eyes of our children and admit that we continue to lose biodiversity at an unprecedented rate, thus mortgaging their future."
Earlier this year, the UN published a major assessment - the Global Biodiversity Outlook - indicating that virtually all trends spanning the state of the natural world were heading downwards, despite conservation successes in some regions.

It showed that loss and degradation of forests, coral reefs, rivers and other elements of the natural world was having an impact on living standards in some parts of the world - an obvious example being the extent to which loss of coral affects fish stocks.

In his opening speech, Mr Matsumoto suggested impacts could be much broader in future.
"All life on Earth exists thanks to the benefits from biodiversity in the forms of fertile soil, clear water and clean air," he said.
"We are now close to a 'tipping point' - that is, we are about to reach a threshold beyond which biodiversity loss will become irreversible, and may cross that threshold in the next 10 years if we do not make proactive efforts for conserving biodiversity."
Climate clouds
In recent years, climate change has dominated the agenda of environmental politics.
And Achim Steiner, executive director of the UN Environment Programme, suggested there is a lack of understanding at political levels of why tackling biodiversity is just important.

"This is the only planet in this Universe that is known to have this kind of life," he said.
"This fact alone should give us food for thought, But more importantly, we are destroying the very foundations that sustain life on this planet; and yet when we meet in these intergovernmental fora, society somehow struggles to understand and appreciate what it is what we're trying to do here, and why it matters."
On the table in Nagoya is a comprehensive draft agreement that would tackle the underlying causes of biodiversity loss, as well as setting new targets for conservation.
At the heart of the idea is the belief that if governments understand the financial costs of losing nature, they can adopt new economic models that reward conservation and penalise degradation.
A UN-sponsored project called The Economics of Ecosytems and Biodiversity (TEEB) calculates the cost at $2-5 trillion per year, predominantly in poorer parts of the world.
Jane Smart, head of the species programme at the International Union for the Conservation of Nature (IUCN), said that although the problem was huge and complex, there were some encouraging signs.
"The good news is that when we carry out conservation, it does work; we increasingly know what to do, and when we do it, it works really really well," she told BBC News.
"So we need to do a lot more conservation work, such as protected areas - particularly in the sea, in the marine realm - we need to save vast areas of ocean to protect fish stocks - not to stop eating fish, but to eat fish in a sustainable way."
Triple win
Governments first agreed back in 1992, at the Rio Earth Summit that the ongoing loss of biodiversity needed attention. The CBD was born there, alongside the UN climate convention.
It aims to preserve the diversity of life on Earth, facilitate the sustainable use of plants and animals, and allow fair and equitable exploitation of natural genetic resources.
The UN hopes that a protocol on the final element - known as access and benefit sharing (ABS) - can be secured here, 18 years after it was agreed in principle.
However, the bitter politicking that has soured the atmosphere in a number of UN environment processes - most notably at the Copenhagen climate summit - looms over the Nagoya meeting.
Some developing nations are insisting that the ABS protocol be signed off before they will agree to the establishment of an international scientific panel to assess biodiversity issues.
The Intergovernental science-policy Platform on Biodiversity and Ecosystem Services (IPBES) is due to be signed off during the current UN General Assembly session in New York.
Many experts - and Western governments - believe it is necessary if scientific evidence on the importance of biodiversity loss is to be transmitted effectively to policymakers.
