This book is a collective academic response from environmental law scholars sharing an interest in Welsh perspectives on today’s local and global environmental challenges. The editors brought colleagues together at a ground-breaking colloquium at Swansea University in April 2011, seeking to foster new legal approaches at a time that sees a new dynamic toward a devolved Wales, including in the environmental policy field. This afforded the opportunity to reflect on pressing environmental quandaries, and to bring together contributors’ conceptual insights and technical legal know-how in identifying ideas for potential responses and solutions. These environmental problems with palpably global implications, such as climate change, thus require engagement at regional and local levels to look to the future.
