It’s Noah’s Ark but not as we know it

January 17th, 2011

In the movie 2012 (roundly criticised

by scientists for being wildly unrealistic), the world as we know it ends in a great flood and people only survive by virtue of giant

arks – in the same vein as Noah’s famous vessel but infinitely

more advanced. Old Noah has done more than inspire

Hollywood; he has also provided the basic idea from which other great minds have leapt, such as Russian architect Alexander Remizov, who has designed an eco-friendly dome capable of withstanding biblical floods.

Remizov’s dome, unimaginatively called “The Ark” is designed to be constructed in a very short period of time (under six months), uses eco-friendly materials and is entirely self-sustaining. It can be built for life on land or on water and is capable of withstanding earthquakes and tornados.

Remizov designed the dome with one of his colleagues, Lev Britvin, in connection with the International Union of Architects’ Disaster Relief programme. In line with the principles of the union’s “Architecture and Renewable Energy Sources” programme, the Ark doesn’t require external support systems, can be constructed quickly in adverse climate conditions and its construction has minimal impact on the environment.

The Ark is built from wood, steel, high-tech plastic, and solar panels and can be scaled to accommodate between 50 and 10 000 people. Instead of glass, Remizov uses a high-tech durable and self-cleaning foil, which is transparent so that indoor plants can grow. An indoor jungle will help establish a microclimate, while energy will be generated from the sun and wind.

In an email interview with the Star, Remizov said, “I like the idea of creating an independent-from-power-networks building that can be constructed in the most beautiful places, including the water surface, while respecting the environment. The building (would have an) organised community which has everything necessary for its prosperity and growth.”

Remizov is currently in discussions with investors and the Russian Council of Sustainable Buildings, to bring his vision to life.

Other ideas for futuristic, self-sustaining biospheres include:

Lilypad, a floating ecopolis is designed by Vincent Callebaut Architects as an “auto-sufficient amphibious city”. It is based on the capable design of the lily pads found in the Amazon River basin and incorporates all aspects of eco-living to achieve a “positive energetic balance with zero carbon emission”. It will be able to accommodate up to 50 000 people.

The Magic Mountains designed by the CEBO/Chongqing University architect team is a series of green buildings in the business district in Chongqing, China which are built to mimic the surrounding mountainous landscape. The unique design is not simply for aesthetics but will also optimise the passive heating and cooling system and reduce energy consumption. The Magic Mountains are effectively a self-contained city in which only walking and cycling will be permitted.

Will China lead the fight against climate change?

January 17th, 2011

When Beijing hosted the Olympics in 2008 much hue and cry was made of the appalling pollution and the fact that one very seldom saw blue sky. There were rumours that the government went to extreme measures to bring the level of contamination down, at least temporarily, such as limiting the number of cars on the city’s roads and shooting chemicals in the sky (which seems counter-productive). Whatever it did, worked and very few athletes complained of the conditions. But after the crowds left the smog and smoke were back and Beijing’s citizens dug out their surgical masks.

China is notorious for its carbon emissions, as well as its apparent reluctance to do anything about them. The perception is not helped much by public statements like those issued in February 2010 by Su Wei, the chief negotiator of China for climate change talks in Copenhagen and the director of the department for combating climate change under the National Development Reform Commission. According to Su Wei, China would not set an upper limit on greenhouse gas emissions as “China’s greenhouse gas emissions have to grow correspondingly as the country still has a long way to go in improving people’s livelihoods and eradicating poverty”.

Su Wei added, however, that the country would do everything it could to fight the negative effects caused by global warming and cut carbon intensity. Not many people took comfort in that.

That was then

By November 2010, China seemed to have changed its tune when, one week before the UN Cancun Conference, it vowed to “effectively control” emissions over the next five years. It also reiterated its dedication to reduce its carbon intensity by 40 – 45% by 2020.

According to Xie Zhenhua, deputy director of the National Development and Reform Commission (NDRC), China has cut carbon emissions by about 1.5 billion tones. This is a result of energy-saving and emission-reduction measures in its 11th Five-Year Plan (2005-2010). “The size of the emission reduction is greater than any other country in the world. This is China’s contribution (to preventing global climate change),” said Xie. Considering that China is the world’s biggest emitter of carbon dioxide, this is less impressive than it sounds.

Looking ahead

What is heartening is the fact that China is dedicated to reducing carbon emissions, carbon intensity and the effects of climate change. It’s been suggested that China might even provide a leading example for the rest of the world. It starts with engaging local municipalities, education and incentives and is being driven by a government that really has no choice.

Pollution is expensive; it costs the country 8 – 12% of its GDP annually, it’s estimated that 460 000 people die from pollution-related causes every year and it has led to large-scale desertification, which will probably never be reversed.

Jonathan Watts, Asia Environment correspondent for the Guardian, says that China’s environmental problems are worse than assumed, but that it’s “doing more to try and solve them than people give them credit for”.

This can be seen in the country’s recognition of its dire water problem (50% of China’s water is considered too contaminated for human consumption), its programme to try and reclaim desert land (which is a very long-term plan – at least 300 years), its intention to address problematic farming methods and the tightening of environmental laws, which are currently vague, ambiguous and not adequately enforced.

China’s environmental problems are many, and attempts to combat them will be fraught with challenges, most notably the continued need for development, but with the government and NGOs finally agreeing to certain measures, and growing public awareness there could be blue skies on China’s horizon.

Lewis Gordon Pugh: The Best Cold Water Swimmer In The World

June 24th, 2010
Lewis Gordon Pugh

Lewis Gordon Pugh is well-known for his (crazy?) cold water swimming. An environmental campaigner, extreme swimmer, lawyer and motivational speaker, it seems there’s little this inspirational man can’t do.

Born in Plymouth, England and having spent some time studying at the University of Cape Town, Lewis is a global man and spends much of his time traveling the world, swimming and speaking at events to raise awareness for issues he feels strongly about. He has a busy speaking schedule, undertaking to do over 100 talks a year around the world – his leadership speech in America at the Business Innovation Forum Conference has been voted one of the 7 most inspiring video talks not he internet. He is widely liked within global media and his topics range from “Vision”, “Goal Setting” and “Planning and Preparation” to “Power of the mind”, “Self Belief” and “Protecting the Environment”.

Lewis was the very first man to complete long distance swims in every ocean in the world, and is arguably known as the best cold water swimmer there is. He says on a simple level he loves pushing boundaries and is passionate about swimming. But on a deeper level he sees and experiences first-hand the effects of climate change – he swims in water from melting glaciers.
Last night (Wednesday 23 June) Kalkbay Books (funnily enough, situated in Kalkbay) presented an interview with Lewis Gordon Pugh to launch his new book “Achieving The Impossible”. I was lucky enough to attend the launch with my mom and aunt.

Two things I must say about Lewis; firstly he has an insanely quick and refreshing sense of humour, secondly Lewis is truly a down-to-earth and honest person. He has swum in some of the most extreme conditions and in vulnerable ecosystems. In 2007 he was the first person to swim across the North Pole. His reason – to highlight the melting Arctic sea ice. In 2010 he undertook to swim across the glacial lake on Mount Everest. This time to highlight the Himalayas’ melting glaciers.

The water degrees (2 degrees C) and the altitude (5,300m) meant that this was one of Lewis’ most difficult swims. On May 22 2010 Lewis commenced his 1km swim. He wants the world to know that these (melting) glaciers are a lifeline, and the effects of them disappearing will be catastrophic. Approximately 2 billion people rely on these Himalayan glaciers for their water supply. Lewis relies heavily on the strength and knowledge of the team behind him. He is openly grateful to the doctors, scientists and coaches who support and aid him in his actions.

During the intimate interview, we got a view of a humble man who felt his career as a lawyer was not enough for him some years back, and who has been inspired by his mother’s “never give up” attitude to really reach far beyond what most people would think they could reach. In the question and answer session, Lewis answered queries with insight and humility – about his past swimming endeavours, about his childhood and his time spent in the icy waters.
He is passionate about our planet and the ever-growing issue of climate change, and is not apologetic about this – when asked what he is doing locally he said he felt the main issue to focus on right now is climate change which is global. He admitted that he wasn’t involved in any local initiatives, as he explained that he felt the issue of climate change was the right battle for him to be fighting. His aim is to get stubborn world leaders to listen to their pleas so maybe something could be done about the situation.

When I asked him what was next he replied that the Himalayas are still in the spotlight for him and his team. He is planning a 150-day swim, and will be planning, training and organising this next trip for the next few months. He is not even sure it can be done, but if his past experiences and adventures are anything to go by there is very little that will stop this amazing swimmer. Watch his regularly updated website for more info.
Lewis won the crowd over, easily. Everyone in the room wanted to hear what he had to say, and, I hope, were inspired by his passion and dedication. After the questions were all asked and the answers given, either in seriousness or in a joking way with playful look in his eye, both my aunt and mother eagerly stood in line to get him to sign their newly acquired book, written by an inspiring author – Lewis Gordon Pugh.

What a magical evening with a motivational personality who has a great sense of humour and modesty, Lewis, it was very nice to meet you.

Greenpeace on climate control

June 10th, 2010

In a recent online article Greenpeace talk about how renewable resources can create around 8.5 million jobs by 2030!1214808_decommissioned

Their whole campaign is to try get countries and corporations to see the value of investing in people rather than “dirty and dangerous” fossil fuels.

If these statistics are true then why aren’t these countries and corporations convinced?

Greenpeace’s argument is pretty persuasive numbers-wise – according to them the global market for renewable energy sources could be worth around 600 billion dollars by 2030.

While some countries are pledging to lower their emissions, there has not been an across-the-board emissions cut target.

Greenpeace have even proffered a detailed report on how to go about cutting carbon emissions while concurrently building economic growth.

So, why is no one listening closely to Greenpeace? You can read the full article here: http://economictimes.indiatimes.com/news/news-by-industry/jobs/Renewables-can-create-85-mn-jobs-Greenpeace/articleshow/6019620.cms

And tell me what you think.
