If you ask a local from the Kansas City area where the West Bottoms are located, several would not be able to pinpoint the location. But a quiet renaissance has begun, reviving the area and reminding locals of its existence. |

Every city has streets where you won’t feel completely safe from crime. Research has shown that ‘fear of crime’ affects urban walkability, but now a new project has shown that the reverse may also be true: that improving the walkability of a street can reduce the number of crimes in an area. |

Most of the history of cities is underground. Evidence of foundations below the surface can tell us what buildings used to be on the site, and artifacts could reveal what life was like for a building’s occupants. These discoveries don’t just provide historical insight – they can also influence current urban development. |

An often under-utilised resource sits above our cities – the roofs of buildings. But as the world urbanises and cities become more dense, rooftops are beginning to be used more efficiently. This project in Yemen shows how a bit of creative thinking can solve a local challenge. |

Recycling and re-use are novel notions for space programmes. So why bother? Because the abandoned equipment in space originally cost $300 billion, and a lot of it would still work. And putting new payloads into orbit costs around $20,000 per kilo. Re-use could be a whole lot cheaper. |
