In coastal aquifers, saltwater intrusion may cause serious consequences in terms of both environmental and economic impacts. An attempt has been made in the present study to elucidate the quality of groundwaterin the study area in terms of the chemical parameter change due to the seasonal variation of water level. The present study deals with the physio-chemical characteristics of groundwater quality in Nagapattinam district.The study area showed generally similar hydrochemical characteristics slightly higher level of Cl-, Na+, and EC was observed. Based on the Cl- , Na+ and EC data, the groundwater falls within high salinity.

The rise of industrial capitalism in the nineteenth century forged a new ecological order in North American and Western European states, radically transforming the environment through science and technology in the name of human progress. Far less known are the dramatic environmental changes experienced by Eastern Europe, in many ways a terra incognita for environmental historians and anthropologists. A New Ecological Order explores, from a historical and ethnographic perspective, the role of state planners, bureaucrats, and experts—engineers, agricultural engineers, geographers, biologists, foresters, and architects—as agents of change in the natural world of Eastern Europe from 1870 to the early twenty-first century. Contributors consider territories engulfed by empires, from the Habsburg to the Ottoman to tsarist Russia; territories belonging to disintegrating empires; and countries in the Balkan Peninsula, Central and Eastern Europe, and Eurasia. Together, they follow a rhetoric of “correcting nature,” a desire to exploit the natural environment and put its resources to work for the sake of developing the economies and infrastructures of modern states. They reveal an eagerness among newly established nation-states, after centuries of imperial economic and political impositions, to import scientific knowledge and new technologies from Western Europe that would aid in their economic development, and how those imports and ideas about nature ultimately shaped local projects and policies.

Named one of the best books of 2015 by The Economist A provocative exploration of the “new ecology” and why most of what we think we know about alien species is wrong For a long time, veteran environmental journalist Fred Pearce thought in stark terms about invasive species: they were the evil interlopers spoiling pristine “natural” ecosystems. Most conservationists and environmentalists share this view. But what if the traditional view of ecology is wrong—what if true environmentalists should be applauding the invaders? In The New Wild, Pearce goes on a journey across six continents to rediscover what conservation in the twenty-first century should be about. Pearce explores ecosystems from remote Pacific islands to the United Kingdom, from San Francisco Bay to the Great Lakes, as he digs into questionable estimates of the cost of invader species and reveals the outdated intellectual sources of our ideas about the balance of nature. Pearce acknowledges that there are horror stories about alien species disrupting ecosystems, but most of the time, the tens of thousands of introduced species usually swiftly die out or settle down and become model eco-citizens. The case for keeping out alien species, he finds, looks increasingly flawed. As Pearce argues, mainstream environmentalists are right that we need a rewilding of the earth, but they are wrong if they imagine that we can achieve that by reengineering ecosystems. Humans have changed the planet too much, and nature never goes backward. But a growing group of scientists is taking a fresh look at how species interact in the wild. According to these new ecologists, we should applaud the dynamism of alien species and the novel ecosystems they create. In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature’s wildness and capacity for change.

Often cited as one of the most decisive campaigns in military history, the Seven Days Battles were the first campaign in which Robert E. Lee led the Army of Northern Virginia-as well as the first in which Lee and Thomas "Stonewall" Jackson worked together.

Climate Fiction and Cultural Analysis argues that the popularity of the term "climate fiction" has paradoxically exhausted the term's descriptive power and that it has developed into a black box containing all kinds of fictions which depict climatic events and has consequently lost its true significance. Aware of the prospect of ecological collapse as well as our apparent inability to avert it, we face geophysical changes of drastic proportions that severely challenge our ability to imagine the consequences. This book argues that this crisis of imagination can be partly relieved by climate fiction, which may help us comprehend the potential impact of the crisis we are facing. Strictly assigning "climate fiction" to fictions that incorporate the climatological paradigm of anthropogenic global warming into their plots, this book sets out to salvage the term's speculative quality. It argues that climate fiction should be regarded as no less than a vital supplement to climate science, because climate fiction makes visible and conceivable future modes of existence within worlds not only deemed likely by science, but which are scientifically anticipated. Focusing primarily on English and German language fictions, Climate Fiction and Cultural Analysis shows how Western climate fiction sketches various affective and cognitive relations to the world in its utilization of a small number of recurring imaginaries, or imagination forms. This book will be of great interest to students and scholars of ecocriticism, the environmental humanities, and literary and culture studies more generally.

Though still a relatively young field, the study of Latin American environmental history is blossoming, as the contributions to this definitive volume demonstrate. Bringing together thirteen leading experts on the region, A Living Past synthesizes a wide range of scholarship to offer new perspectives on environmental change in Latin America and the Spanish Caribbean since the nineteenth century. Each chapter provides insightful, up-to-date syntheses of current scholarship on critical countries and ecosystems (including Brazil, Mexico, the Caribbean, the tropical Andes, and tropical forests) and such cross-cutting themes as agriculture, conservation, mining, ranching, science, and urbanization. Together, these studies provide valuable historical contexts for making sense of contemporary environmental challenges facing the region.
