The importance of Environmental Studies cannot be disputed since the need for sustainable development is a key to the future of mankind. Recognizing this, the Honourable Supreme Court of India directed the UGC to introduce a basic course on environmental education for undergraduate courses in all disciplines, to be implemented by every university in the country. Accordingly, the UGC constituted an expert committee to formulate a six-month core module syllabus for environmental studies. This textbook is the outcome of the UGC s efforts and has been prepared as per the syllabus. It is designed to bring about an awareness on a variety of environmental concerns. It attempts to create a pro-environmental attitude and a behavioural pattern in society that is based on creating sustainable lifestyles and a new ethic towards conservation. This textbook stresses on a balanced view of issues that affect our daily lives. These issues are related to the conflict between existing `development strategies and the need for `conservation . It not only makes the student better informed on these concerns, but is expected to lead the student towards positive action to improve the environment. Based on a multidisciplinary approach that brings about an appreciation of the natural world and human impact on its integrity, this textbook seeks practical answers to make human civilization sustainable on the earth s finite resources. Attractively priced at Rupees One Hundred and Fifteen only, this textbook covers the syllabus as structured by the UGC, divided into 8 units and 50 lectures. The first 7 units, which cover 45 lectures are classroom teaching-based, and enhance knowledge skills and attitude to environment. Unit 8 is based on field activities to be covered in 5 lecture hours and would provide students with first hand knowledge on various local environmental issues.
