Air pollution is a huge problem for China, but did you know it’s actually getting better? The Air Quality Index in several cities is improving, because of a variety of experimental projects that are being rolled out.
In this special edition of World Hacks as part of the #SoICanBreathe season, we are in Beijing to gather together some of the thinkers and entrepreneurs leading China’s efforts to clean its air. We work through their ideas with an audience of students and entrepreneurs, as well as hearing reports about clever pollution solutions from around the country.Presented by Mukul Devichand and Vincent Ni.

But a small group of academics and activists in the US are experimenting with a new way of getting people to turn up and put their cross in a box – a lottery. Every voter is entered and one lucky winner gets a big cash prize. World Hacks investigates whether it works.Presenter: Kathleen Hawkins Reporter: Gemma Newby Producer: Tom CollsImage caption: Lottery balls about to be drawn, Image credit: Thomas Samson / Stringer / Getty Images

Folge vom 18.02.2017Denmark’s Food Waste VigilanteFood waste is a massive global problem: the EU alone throws away 88 million tonnes a year. Much of this ends up in landfill and produces dangerous greenhouse gasses which contribute to climate change. In Europe 53% of food waste comes from households, and one woman has made it her mission to stop Danes throwing away food. We travel to Copenhagen to meet Selina Juul, a key part of Denmark’s food waste revolution.

Folge vom 11.02.2017The Sun Water SolutionThis is a story about how the most amazing ideas do not always work how you would like in practise. In theory it is so simple. You put disease-ridden water into a two litre plastic bottle, screw on the lid and leave it in the sun. After six hours on a cloudless day, almost all the bacteria and bugs that cause diseases like cholera and diarrhoea are killed or inactivated by the UV light and gentle warming. Professor Kevin McGuigan has proven this in the lab, but for the last 20 years he has been trying to get it working in rural African communities. It has not been anywhere near as easy as you might think.(Photo: Godfrey putting his water bottle out to disinfect in the sunshine)
