In Wales, the average citizen uses almost three times their share of the world's resources. But Cassandra [Lishman] and her family are part of a groundbreaking scheme launched by the Welsh government in 2011 that aims to address that imbalance. The One Planet Development Policy (OPD) and its predecessor, Pembrokeshire's Policy 52, allow people to bypass tight planning laws and move to protected areas to live ecologically sustainable lifestyles. So far, 46 individual smallholdings have signed on to the programs, which require residents to sustain themselves using the resources available on land they inhabit. The policy aims to combat an array of problems: rising temperatures, soil degradation, rural depopulation, a rampant housing crisis and wasteful global supply chains. But ... by limiting consumption and allocating resources wisely, ecologically responsible development is possible, even in pristine environments. To qualify for the scheme, there are four requirements. First, each household must use only their global fair share of resources, which has been calculated by the Welsh government as equivalent to six acres of land. Second, applicants must show that within five years this land can fulfill 65 percent of their basic needs, including food, water, energy and waste. Third, they must come up with a zero-carbon house design using locally sourced and sustainable materials. Finally, they must set up a land-based enterprise to pay the sort of bills ... that can't be met with a subsistence lifestyle.
