14 maltatoday | WEDNESDAY • 7 DECEMBER 2022 NEWS CLIMATE change is one of the greatest threats ever to face hu- manity. With mounting storms, fires, floods and droughts and the annual disappointment of international negotiations, it's easy to despair about how bad the future climate will be. But exciting work is being done to find solutions. This is where the Prince of Wales's Earthshot prize makes a difference. The prize celebrates and supports solutions to save the planet by giving each winner £1 million (US$1.2 million) to de- velop their innovations. There are five categories, with three finalists and one ultimate win- ner in each. Here are the winners of the Earthshot prize in each of the categories. Safe air: Mukuru clean stoves, Kenya Charlot Magayi grew up in Mukuru, one of the biggest slums in Nairobi, Kenya. She was orphaned at the age of ten and became a mother at 16. She used a traditional stove fuelled by firewood to cook food for her family, a method that cre- ates indoor air pollution and kills over two million people worldwide each year. Her daughter suffered a se- vere burn from the stove when it fell on her when she was only two. Magayi vowed to develop a safer alternative. She went to college and invented a more stable and efficient stove that uses 60% less fuel and can run on smokeless fuel if available. Mukuru clean stoves are made from locally sourced waste metal and can reduce toxic air pollution by up to 90%, while also reducing carbon emis- sions. The increased efficiency reduces the burden on women who must spend hours each day collecting firewood. Adapting to climate change: the greenhouse in a box, India When Sathya Raghu Mok- kapati was just 17 years old, he saw a farmer in his village eating mud. When Mokkapati asked him why he said: "I'm a farmer, my crops have failed. My stomach doesn't know that my pocket is empty." Mokkapati teamed up with entrepreneur Kaushik Kappa- gantulu and the pair spent six months travelling India meet- ing hundreds of farmers who told the same story: it did not matter how hard they worked, unpredictable weather linked to climate change could wipe out their crops, reduce their income to zero and leave them to starve. There are over 600 million farmers globally tending plots smaller than two hectares, and collectively, they grow nearly a third of the world's food. As part of an international team, Earthshot Prize: five winners that will help Prince William at the awards in Boston, US Mokkapati and Kappagantulu created a greenhouse in a box that protects crops from the elements during the worst weather and even provides irrigation
