How does your city sound? Are we even aware of the noises that surround us on a daily basis? A new project is asking residents of Edinburgh, Sheffield and Brighton and Hove to take part in a survey of sound with the hope it'll help preserve areas of quiet and reduce noise pollution. BRENDAN MONTAGUE reports
Ahead of this week's 29th meeting of the CITES Animals Committee, in Geneva, Switzerland, the London-based Environmental Investigation Agency (EIA) reveals how the legal trade in lion bones from captive-bred lions serves only to exacerbate and drive the illegal trade in wild tiger parts
By shifting from globalisation to localisation, and creating smaller, self-sufficient communities within sustainable developments, cities could regain their equilibrium, writes Paul Jones. From where we stand today, the Organicity may sound like a Utopian dream. But if we're to avoid an urban apocalypse, we're going to need strong alternative visions, to change the way we imagine and plan for the cities of the future. Too good to be true? Or the way to human survival?
A crucial component of concrete, sand is vital to the global construction industry, writes Nick Meynen. China alone is importing a billion tonnes of sand a year, and its increasing scarcity is leading to large scale illegal mining and deadly conflicts. With ever more sand fetched from riverbeds, shorelines and sandbanks, roads and bridges are being undermined and beaches eroded. And the world's sand wars are only set to worsen.
Ten villages and surrounding farmland have already been wiped from the map for a 50 sq.km airport and surrounding 'aeropolis' or airport city in West Java, Indonesia, writes Rose Bridger. And while investors are offered an 'attractive incentives plan', villagers are subject to fierce state repression and brutality. Now only a single village remains standing, but residents continue to resist eviction and demand an end to the project.
The facts are simple: a new London runway means more planes, more noise, more pollution and more global warming, write David Howarth & Steven Griggs. The 'Heathrow 2.0' initiative's conflation of 'sustainability' and 'sustainable growth' and its avoidance of climate change reek of Trumpian 'alternative facts'.
The government's 'misclassification' of an eight-lane M25 road bridge over the river Thames East of London as a 'rural road' meant they did not have to report the illegal levels of pollution found there, writes Keith Taylor - getting off the UK off the hook for a 17th breach of EU air quality standards. What an unfortunate error!
The green belt is part of the critical green infrastructure that delivers multiple benefits for cities, writes Alister Scott. It provides space for recreation, biodiversity and farms supplying local food. It protects us from flooding and drought, improves air quality and mitigates the urban heat island effect. In short, it's far too valuable to allow developers to build all over it!
London Mayor Sadiq Khan promised electors that he would be the 'Greenest Mayor ever'. In spite of his apparent support for a new Thames road crossing in East London and an expanded London City Airport, he still has huge opportunities to make good his pledge. And Green Assembly Members will be working hard to make sure he does.
First we heat up cold water for baths, showers and washing, write Jan Hofman & Laura Piccinini. Then we chuck all that precious heat down the plughole. So how about recycling our waste heat to warm up water on its way to the boiler or hot water tank, cutting bills and emissions? Or on a larger scale, use the sewage from entire communities as a free energy source for heat pumps?
A proposed redesign of the Natural History Museum's grounds in London would cause some unfortunate collateral damage, writes Gary Grant - the destruction of the Museum's 21 year-old wildlife garden, an ecological jewel in the heart of London which features over 3,000 species of plant and animal in just one lovingly tended acre. The Museum must think again!
Bristol's decision to trial vinegar as a weedkiller in place of glyphosate certainly grabbed headline-writers' imaginations, writes Harriet Williams. But with a wide choice of proven chemical-free weed control strategies available, might this experiment be 'set up to fail'?
Stop Killing Cyclists are staging a protest in London on 27th April to demand an end to the UK's intolerable air pollution, writes Donnachadh McCarthy. With an estimated 40,000 people dying every year from filthy air, much of it caused by diesel cars, all are welcome to join in, denounce the government's 'polluters' friend' policies, and insist on swift action to stop the needless deaths.
Low Emissions Zones have their place in cleaning up the UK's worst air pollution hotspots, writes Richard Howard. But we also need to adopt fiscal measures to encourage a shift away from diesel vehicles, at once delivering cleaner air, increased tax revenues, and lower carbon emissions.
The lead poisoning crisis in Flint, Michigan is just the tip of a vast iceberg of lead contamination afflicting mainly urban black communities, writes Leif Fredrickson. A rigid 'race bar' on postwar suburban housing and mortgages left black families in inner cities, exposed to flaking lead paint in run down housing, leaded gasoline residues and lead pipework. Now is the time to correct this shocking historic injustice.
Today's threats of legal action by ClientEarth against the UK Government highlight the problem of London's poisonous air, which is killing some 10,000 people a year, writes John Weeks. Fortunately there are simple, low cost, effective measures that could be taken to bring about big improvements to the city's air quality, fast.
Just as rich and poor are separated by walls of money, the Latin American trend is to add physical walls to keep wealthy and deprived communities entirely apart, write Camillo Boano & Belen Desmaison. On the one side people enjoy lavish homes, security, public services and piped water. On the other residents live in tiny shacks built of scraps, in a desert landscape ruled by criminals.
Britain's 20th century architecture is in danger of obliteration, writes Sebastian Messer, with a 'new brutalism' that holds that socially deprived council estates are fit only for demolition. But these buildings are an important part of our cultural heritage, and more than that, they provide affordable housing to millions of people.
Erdogan's horrific 'war on terror' in the Kurdish cities of Eastern Turkey may have a silver lining, writes Defne Kadıoğlu Polat - at least for property developers and ruling party insiders. Plans are already under way for 'urban renewal' projects that will see the valuable real estate cleansed of buildings and people by the war developed into luxury apartments and shopping malls.
Demolishing 'sink' council estates is no way to solve social problems, writes Loretta Lees. All it does is force low income communities out of affordable housing, and open valuable urban sites up for profitable redevelopment. But then, maybe that's the point?
