All pollution is taught at length in environmental science engineering life sciences and social science courses. The syllabi of these courses are as vast and varied as the dimensions of this global problem. Consequently there is ever increasing need of information on sources effects and control of air pollution. The present book is an attempt in this direction and has been particularly written to fill up the visible gaps in the information required by various users in India. Having taught this subject for over two and a half decades the authors were constantly conscious of a comprehensive book in this field. The book has 20 chapters and an appendix dealing extensively on history of air pollution primary and secondary air pollutants industrial sources of air pollution automobiles generated air pollution natural air pollution the effects of air pollution on plants and man as well as on property and cultural heritage. The global effects like ozone depletion and green house effects are discussed incorporating most latest developments in the field. Air pollution meteorology is discussed in considerable detail. Subject of air pollution has received attention especially after supreme court directive for states to start Environmental Science course in undergraduate colleges of all universities in India. 284 pp.…

Hardcover. Condizione: New. Wetlands are transitional areas between aquatic and terrestrial ecosystems where the water table is usually at or near the surface, or the land is covered by shallow water. Wetlands are among the most productive life support systems in the world and are of immense socio-economic and ecological importance to mankind. In India wetlands are distributed in different geographical regions. Wetlands play critical role in the improvement of water quality through the arrest of pollutants (organic inorganic) from direct release to the natural water bodies and by removal of sediments, production of oxygen, recycling of nutrients, and treatment of wastewater by removing nitrogen, phosphorus, bacteria and viruses. The wetlands act as habitat for fish shellfish, and for birds, mammals, reptiles amphibians, many of which are of economic value in terms of subsistence and commercial fishing, hunting and trapping. Non-consumptive uses of the wetlands, viz. bird watching, recreation, aesthetics, educational activities, and scientific research are also well recognized. Population pressures in the past few decades led to rapid utilization of natural resources for land based development. In this process wetlands were treated with contempt. Ignoring their importance, wetlands were considered obstacles in the path of progress and reservoirs of diseases. Wetlands were hence drained, filled and reclaimed for more economic gains. The rivers were dammed, regulated and channellized leading to modification or elimination of floodplains. This led to a considerable alteration of wetland habitats and the composition of associated flora and fauna. A select list of activities that affected wetlands is presented in Table - 1. In the recent past importance of wetlands has been realized by the policy makers worldover and efforts are being made to protect the wetlands from further deterioration and loss. Environmental Impact Assessment (EIA) is potentially one of the most valuable, inter-disciplinary and objective decision-making tools with respect to alternate routes for development, process technologies and project sites. It is an anticipatory mechanism which establishes quantitative values for parameters indicating the quality of the environment and natural systems before, during and after the proposed developmental activity, thus allowing measures ensuring environmental compatibility and economic efficacy. EIA is designed to present a clear and concise picture of all benefits and costs associated with alternative courses of action, and thus provides a mechanism for merging concerns for ecology and economics in the process of decision-making. In many cases developmental activities adversely affect wetland benefits which are of value to communities and natural processes. EIA can provide very useful information on how wetlands will be affected by the proposed developmental activities to ensure effective management of wetlands. EIA can help planners make rational decisions about resource allocation and ensure that the wetland benefits required for sustainable development are maintained. The objective of this manual is to assist project proponents, conservation activists and decision makers to identify the wetland benefits present at a particular site as also benefits which are likely to be adversely affected by a particular project activity. This would enable assessing the extent and cost of the management plan required to mitigate these impacts. With the backdrop of international conventions for wetland protection and initiatives of the Ministry of Environment and Forests, Government of India, manual delineates step by step procedure for EIA of developmental activities affecting wetland benefits. Worksheets that could enable preparation of case studies are included in the manual. Four casestudies prepared by the institutions that participated in the March 1995 workshop organized by the British Council, at Calcutta, have been included in the manual.…
