Every species plays an important role in maintaining an ecological balance among the living systems of the earth. These systems must continue to function if life is to survive. Loss of any species threatens the survival of several species inclusive of man. Man's own survival depends on his willingness and ability to cooperate with the living environment. Human beings turn to nature and wildlife for spiritual, psychological, physical and cultural benefits. Why should we care about disappearing animals? The answer to such a question can be attributed to many reasons. To protect wildlife many laws are framed and promulgated. This book portrays the real picture of wildlife and many applied laws. This will equip the readers with fundamental knowledge in the field.

Today not only do all human activities, agricultural, transport of industrial, affect human perceptions of the environment but they also have their impact on the ecological system and the resource base. The four point focus of population, resources, development and environment gives rise to a complexity of relationships which both the development planner and the environmental manager has to take into account. Man likes, at least occasionally, to live in forest, hillsides and on seashores. Any society would be resentful if these are spoiled and rendered unusable. Natural beauty spots are easy to destroy and they are difficult and costly, and often impossible, to regenerate.

The world environment has deteriorated in all dimensions, Thus, conservation is a practice embracing preservation maintenance, sustainable utilization, restoration and enhancement of the natural environment.

The book presents kaleidoscopic view of all major aspects of world environment. Thus, current scenario of world environment is portrayed vividly. Natural resources; environmental protection; air pollution; water pollution; atmosphere; natural environment and management; land management etc. are the main topics competently dealt with in this volume.

This encyclopaedia has been essentially a compilation and editing of terms and expressions to provide a reference source for students of agriculture, farmers, environmentalists, biologists, geologists, biochemists, rural economists, and all those involved in or associated with the agriculture in whatever capacity. This encyclopaedia is concerned essentially with agriculture, biology, geography, physical geomorphology, and chemical and rural economics terms as may be needed to provide adequate information. Entries also incorporate the most common and agriculturally significant diseases and pests of farm animals or crops with their symptoms.

The entries have been written in clear and explanatory style to provide both straight forward definitions and invaluable background information. This approach, combined with an extensive cross referencing system, enables the reader to place each entry into a broader scientific context. Line diagrams have been incorporated whenever the meaning of a term can be best conveyed by means of a diagram.

The terms included in this encyclopaedia have been presented in brief analytical phrases thereby avoiding the more comprehensive type of treatment appropriate to large reference works. The extent of each entry has been determined by the need for definition of meaning function and agriculture relevance. Certain entries also have been added to take into account of recent developments and terms in agriculture.

This set will provide a reference work for students of agriculture, biology, geomorphology, environmental science, forestry and biochemistry.

Encyclopaedia of Energy, in five volumes, is a pioneering effort to cover every aspect of energy such as generation/ production, conversion, transmission and use. Comprehensive and well illustrated entries cover fossil and other types of chemical fuel, hydro-electric and nuclear power, energy conservation, solar energy of every kind, wind, wave and tidal energy. Every type of nuclear reactors has been described with emphasis on the energy technologies that have the great relevance and future promise. This set also includes entries relating to a careful explanation of the energy units used and tables of international energy statistics.

No doubt, many will use this work not merely for reference but also as a readable and systematic survey of the energy field, written formally and without lengthy discussion of the controversial issues. This set is an excellent introduction and invaluable reference book for general readers, students and all workers in energy-related fields.
