This week on the Mongabay Newscast, Samantha Murray, CEO of the Indigenous Desert Alliance, joins the program to discuss the IDA’s recent nomination for an Earthshot Prize. The alliance is a network of 70 ranger teams across the Australian desert, covering 270 million hectares (667 million acres), an area almost as large as Argentina. This makes it the largest Indigenous-led conservation corridor on the planet.

Murray and her network of 885 rangers have helped restore biodiversity to 140 million hectares (346 million acres) of land over the past four years using the practice of cultural burning, a cultural and ecological management practice that has been present in Aboriginal culture for millennia. The IDA administers this through its “Right Way Desert Fire” program.
