Soil degradation is reducing crop yields and adding to climate change. It's a big headache not just for farmers, but for all of us.But fear not, as Ed Butler heads to a wheat field in eastern England where farmer Simon Cowell thinks he has a simple, counter-intuitive solution to the problem: Cut back on fertilisers and pesticides, and plough less. He claims it restored his land in two years. But if it's this simple, why isn't everyone doing it? And what happens if we don't do anything? How quickly will we run out of usable soil, and how much carbon will our soils emit into the atmosphere?The programme also features interviews with Ronald Vargas of the UN Food and Agriculture Organization; professor of soil conservation Jane Rickson of Cranfield University; and geologist David Montgomery of the University of Washington.Producer: Josh Thorpe(Picture: Close-up young plant growing in the soil; Credit: Mintr/Getty Images)

Folge vom 13.01.2020The next big thingHow easy is it to predict where tech will take us in the next decade, and have we hit a plateau in the pace of innovation?Manuela Saragosa speaks to author and artist Douglas Coupland, who retells how a mind-bending run-in with a Google research team left him convinced that the next huge development hurtling towards us like a meteor is what he calls "talking with yourself".Science fiction predictions of the future are notoriously wayward - where are the hoverboards and ubiquitous fax machines promised by the Back to the Future films? Nonetheless, forecasting tech developments can be 85% accurate over a 10-year time horizon, according to professional futurologist Dr I D Pearson.But while tech may continue to take us to new and strange places in the long term, has Silicon Valley run out of earth-shattering new products, at least in the short term? The BBC's Zoe Kleinman reports from a rather subdued CES 2020 tech conference in Las Vegas.Producer: Laurence Knight(Picture: Cracked egg containing computer circuitry; Credit: sqback/Getty Images)
