Two decades after the Brundtland Commission''s Report "Our Common Future" adopted the concept of ''sustainable development'', this book provides a renewal of the concept exploring the potential for new practices and fields for those involved in sustainability activity. The book addresses a number of themes concerning firstly, the provision of a "next generation perspective", which was a central, and still unresolved, notion of the original Brundtland definition and, secondly the provision of new milestones for policy and research that can expand the discussion on this second generation concept on sustainability. The material dealt with in the book offers a wide variety of perspectives on sustainability and reflects the importance of interdisciplinary and transdiciplinary work in the field. Suggesting targets for future analytical and political efforts in achieving global sustainability, this book offers new analytical opportunities for holistic politics and research at a general and sector level.
