A smallholder, environmental consultant and writer, Mark Diacono is known for his commitment to sustainable, ethically produced food. He has become synonymous with climate change growing, an approach to producing food that takes sustainable advantage of the new conditions; Otter Farm, his smallholding in East Devon, has become famous as home to the UK's first olive grove, as well as orchards of almonds, peaches and apricots. Mark also works closely with the River Cottage team, and has recently planted a kitchen garden at the River Cottage stores in Axminster.
