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.

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'?
