Graham spent his formative years on a 75 acre farm, surrounded by forest on the eastern seaboard of Nova Scotia, Canada. He received his bachelors from Concordia University in Montréal in 2009, with a specialization in Human Environment and a minor in Ecology and received his PDC at Pacific Permaculture in 2009. Later that year he traveled to Australia to apprentice under Geoff Lawton with the Permaculture Research Institute of Australia (PRI), where he managed Lawton’s nursery. In 2009, he founded P3 Permaculture: a social enterprise with a mission to make permaculture accessible. To date Calder has taught over 16 courses and has certified over 200 students in permaculture.
