Can we improve the modern city by applying Indigenous technologies to food production, flood defences and carbon sequestration? And could a repeat of Australia’s bushfires be avoided by using Indigenous fire management methods? Themed around extinction, reconnection and redesign, this issue explores what we can learn from ancient wisdom to improve the modern world, how plants have survived the worst manmade disasters, and how community groups and retailers are changing the way we access and engage with food and with each other. We also look at how wild coffee plants are being saved from extinction, and hear how Ayisha Siddiqa’s personal history led her to the climate movement.
