The threats from global cultural change and abandonment of traditional landscape management increased in the last half of the twentieth century and ten years into the twenty-first century show no signs of slowing down. Their impacts on global biodiversity and on people disconnected from their traditional landscapes pose real and serious economic and social problems which need to be addressed now. The End of Tradition conference held in Sheffield, UK, was organised by Ian D. Rotherham and colleagues. It addressed the fundamental issues of whether we can conserve the biodiversity of wonderful and iconic landscapes and reconnect people to their natural environment. And, if we can, how can we do so and make them relevant for the twenty-first century. The book is in two parts: Part 1. A History of Commons and Commons Management and Part 2. Commons: Current Management and Problems.
