Geography has a longer genealogy than any other science. In the ancient period, geography grew out of explorations, mapping of the areas known and speculation about the material collected. Though the development, diffusion and spread of geographical knowledge during prehistoric periods, cannot be ascertained. However there is a consensus that all civilizations contributed to the development of geographical concepts.

The present work on Geographical Thought is encyclopedic nature encompassing all relevant information on the theme. Supported by facts and figures derived from various authoritative sources, this will prove a veritable mine of information to one and all concerned.

In order to keep pace with the continuing rapid developments and expanding vocabularies in all areas of environment, an attempt has been made to include old as well as new terms in this dictionary. The terms have been written in clear, simple language that is understandable even to non-specialists but is consistent with the complexity of the term itself.
The environmental movement itself has changed. As governments and industries have taken steps to curb the pollution of the environment while Pollution has not been concerned, to some extent it has ceased to be a matter of primary concern. Some environmentalists have seen nuclear power s a major issue over which they must unite. An attempt has been made to include most entries relating to nuclear power.
Ecology is related to environmental science and is still a now discipline. Terms relating to ecology have been included. The earth sciences too have changed over the last few years mainly as a result of the examination of cores taken from the deep ocean floor. An attempt has been made to include changes to take account of recent findings.
The dictionary will be of value to students of environments and to scientists and engineers working on pollution problems.

Geography stands in the centre of natural sciences and social sciences. It makes use of may disciplines in its definitions. In making various entries in this dictionary (more than 3000) only those terms have been selected which are in common usage. While describing the terms and words the emphasis has always been laid on factual information rather than on a simple definition. At places formulae and statistics have been given for better illustration. Though it is a dictionary of geography yet certain geological terms have been included which a student of geography is likely to come across. This dictionary includes terms from oceanography, weather and climate, surveying and cartography, earth, economic and human geography, archaeology, etc. The definitions are written in clear, simple language that is understandable even to non-specialists but is consistent with the complexity of the term itself. Many definitions are supplemented by detailed, informative illustrations.

This dictionary will be of great assistance to a large number of students in schools, colleges and universities. The book is likely to be useful for general public also

Geography stands in the centre of natural sciences and social sciences. It makes use of many disciplines in its definitions. The present book Encyclopedic Dictionary of Geography includes those terms which are in common usage.

Throughout the process of compilation and editing the volumes, the main effort was to make the dictionary serve as a ready reference manual. The entries have been written in a clear, lucid and explanatory style to provide both straight forward definitions and invaluable background information. This approach, combined with an extensive cross-reference system, enables the reader to place each entry into a broader scientific context. At certain places, the diagrams have been included wherever the meaning of a word can be best understood by means of a diagram. At places formulae and statistics have been given for better illustration. Though it is a dictionary of geography, yet certain geological terms have been included which a student of geography is likely to come across. The main entries included in this dictionary come from oceanography, weather and climate, surveying and cartography, earth, economic and human geography, bio-geography, ecology and ecosystems.
This encyclopedic dictionary is packed with enormous conceptual and factual knowledge which shall be useful for the teachers, students, academicians, policy makers and for those who are interested in geography and earth sciences.
