The Prince of Wales has said he wants his environmental Earthshot prize to "change the world for good" over the next decade as he celebrated this year's winners.
Prince William closed the awards ceremony in Cape Town by calling for people around the world to join the "movement for change". Each of the winners, from five different categories, were awarded £1m ($1.2m) in order to help scale-up their innovative ideas to "repair" the planet.
Fifteen finalists, from countries including France, Kenya, Indonesia, the USA, UK and Nepal, were competing for their category's prize pot after being whittled down from 2,500 applicants. Dubbed the prince's "Super Bowl" moment, the awards were broadcast live across Africa and streamed online. In his closing remarks, the prince said he believed the world could be "rich in possibility, in hope, and in optimism".
“These visionary innovators from Africa and beyond are not just solving the environmental challenges facing their communities – they are lighting the path for a sustainable future for us all,” said Prince William, president of the Earthshot Prize.
The winners from each of the five categories were:
Protect and Restore Nature: Altyn Dala Conservation Initiative, a project that has saved the critically endangered Saiga antelope from extinction in Kazakhstan.
Clean Our Air: Green Africa Youth Organization, who use behavioural change to help communities clean up waste and build circular waste management infrastructure across Africa.
Revive Our Oceans: High Ambition Coalition for Nature and People, an alliance of at least 119 countries with the ambitious goal to protect 30% of land and oceans by 2030.
Build a Waste-free World: Keep IT Cool, a Kenyan-based company using solar powered refrigeration to help cut harvest waste for farmers.
