Dominant approaches to sustainability have focused on ecological way of life with efficient mechanisms and technical quick-fixes for regulatory changes and policy reforms within the growth-centred economic development. However, they fail to develop a humanitarian ecological for a more fundamental change in the framework of moral values guiding individuals' behaviour and attitude towards the environment and their choices to live lightly on earth. This book argues that the transformation to a sustainable society necessitates deeper moral changes and the development of an ecological morality at the individual level as the core of sustainability. It also examines the distinctiveness of the Gandhian approach to ‘ecological and sustainable development’ within his paradigm of non-violence and ethical holism as an alternative to the dominant thinking. Within his broader moral-philosophical framework, the book focuses on Gandhi's theories of ecolocalism, unity of life and economics of well-being realized by the human self through an ‘inner revolution’ with a goal to bring about a societal transformation towards a sustainable society based on freedom, equity, justice and peace.
