Synopsis This book is the outcome of research papers presented in the international and national conferences / seminars / workshops, by the authors.  This book emphasizes on environmental to function indefinitely without going into a decline from the stresses (such as soil, water, and air) that maintain life.  When the environment is sustainable, humanity’s present needs are met without endangering the welfare of future generations.  The papers have common thread running over different approaches; and providing policy options for achieving sustainable development.  Environmental sustainability should harmonize with economic, social, political, cultural and technological sustainability.  The integration of different sustainabilities is essential in the context of global environmental crises, which threaten the mankind in the form of global warming, ozone layer depletion, acid rain, desertification, loss of biodiversity, and their associated problems. With this background, the authors have made a sincere effort to compile  the selected papers written on different points of time which reverberated the major environmental events in the world.
