Book Description
This volume comprises the proceedings of the Second International Rangelands Congress held in Adelaide, Australia in May 1984, and includes some 350 contributions drawn from 43 different countries. The Congress addressed the problem of the conflict between land-users and the degradation of this valuable resource. Some 40% of the Earth's land surface is and or alpine and therefore unsuitable for agricultural cultivation. Collectively, these lands are known as rangelands and in their natural state they constitute a habitat for grazing animals, both domestic and wild. Despite their low productivity, rangelands have been used for thousands of years as a source of food and fibre, but other uses such as mining, tourism, recreation and conservation are exerting increasing demands. The result is often conflict between land-users and degradation of the resource.

Book Description
This book presents a hypothesis and evidence that organisms promote and ecosystems maximize biodiversity. All species have a net positive effect on their environment, other species, and diversity. The sun is 30% hotter than when life began, but the temperature has been kept moderate by life. Life created high oxygen, the ozone layer, and fertile soil, a diverse, living system. No species evolves in isolation, and most evolution is coevolution. The nature and number of links between species are as important as species number. Eukaryotes coevolve with complex ecosystems of microbes with which they exchange genes. Genomes and intraspecific interactions both act to promote evolution and diversification. Viruses increase diversity of their hosts and cause macroevolutionary transitions. Key Features Life alters the Earth in ways that increase biodiversity All species make their environment better for other species and promote diversity Life created the life-friendly atmosphere, temperature, and soil of today

Book Description
The new revised fifth edition of Natural Hazards remains the go-to introductory-level survey intended for university and college courses that are concerned with earth processes that have direct, and often sudden and violent, impacts on human society. The text integrates principles of geology, hydrology, meteorology, climatology, oceanography, soil science, ecology, and solar system astronomy. The textbook explains the earth processes that drive hazardous events in an understandable way, illustrates how these processes interact with our civilization, and describes how we can better adjust to their effects. Written by leading scholars in the area, the new edition of this book takes advantage of the greatly expanding amount of information regarding natural hazards, disasters, and catastrophes. The text is designed for learning, with chapters broken into small consumable chunks of content for students. Each chapter opens with a list of learning objectives and ends with revision as well as high-level critical thinking questions. A Concepts in Review feature provides an innovative end-of-chapter section that breaks down the chapter content by parts: reviewing the learning objectives, summary points, important visuals, and key terms. New case studies of hazardous events have been integrated into the text, and students are invited to actively apply their understanding of the five fundamental concepts that serve as a conceptual framework for the text. Figures, illustrations, and photos have been updated throughout. The book is designed for a course in natural hazards for nonscience majors, and a primary goal of the text is to assist instructors in guiding students who may have little background in science to understand physical earth processes as natural hazards and their consequences to society.

Book Description
A bold redefinition of historical inquiry based on the “cropscape”—the people, creatures, technologies, ideas, and places that surround a crop Human efforts to move crops from one place to another have been a key driving force in history. Crops have been on the move for millennia, from wildlands into fields, from wetlands to dry zones, from one imperial colony to another. This book is a bold but approachable attempt to redefine historical inquiry based on the “cropscape”: the assemblage of people, places, creatures, technologies, and other elements that form around a crop. The cropscape is a method of reconnecting the global with the local, the longue durée with microhistory, and people, plants, and places with abstract concepts such as tastes, ideas, skills, politics, and economic forces. Through investigating a range of contrasting cropscapes spanning millennia and the globe, the authors break open traditional historical structures of period, geography, and direction to glean insight into previously invisible actors and forces.

Book Description
Long considered both best friend and worst enemy to humankind, fire is at once creative and destructive. On the endangered tropical island of Madagascar, these two faces of fire have fueled a century-long conflict between rural farmers and island leaders. Based on detailed fieldwork in Malagasy villages and a thorough archival investigation, Isle of Fire offers a detailed analysis of why Madagascar has always been aflame, why it always will be aflame, and ultimately, as Christian Kull argues, why it should remain aflame.

Book Description
Flame and Fortune in the American West creatively and meticulously investigates the ongoing politics, folly, and avarice shaping the production of increasingly widespread yet dangerous suburban and exurban landscapes. The 1991 Oakland Hills Tunnel Fire is used as a starting point to better understand these complex social-environmental processes. The Tunnel Fire is the most destructive fire—in terms of structures lost—in California history. More than 3,000 residential structures burned and 25 lives were lost. Although this fire occurred in Oakland and Berkeley, others like it sear through landscapes in California and the American West that have experienced urban growth and development within areas historically prone to fire. Simon skillfully blends techniques from environmental history, political ecology, and science studies to closely examine the Tunnel Fire within a broader historical and spatial context of regional economic development and natural-resource management, such as the widespread planting of eucalyptus trees as an exotic lure for homeowners and the creation of hillside neighborhoods for tax revenue—decisions that produced communities with increased vulnerability to fire. Simon demonstrates how in Oakland a drive for affluence led to a state of vulnerability for rich and poor alike that has only been exacerbated by the rebuilding of neighborhoods after the fire. Despite these troubling trends, Flame and Fortune in the American West illustrates how many popular and scientific debates on fire limit the scope and efficacy of policy responses. These risky yet profitable developments (what the author refers to as the Incendiary), as well as proposed strategies for challenging them, are discussed in the context of urbanizing areas around the American West and hold global applicability within hazard-prone areas.

Book Description
Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.

Book Description
From the time of the continent's formation tens of millions of years ago as the Godwana twin of Antarctica, Australia has been dominated by fire much as its sister has been by ice. Now Stephen Pyne, one of our foremost environmental historians, proposes a major reinterpretation of the Australian experience by using fire and Australia to explain one another. He narrates the story of how fire came to Australia and interacted with the Australian biota and its human inhabitants, while at the same time he relates the planetary saga of fire as it has been played out on this special island continent. Much as the Aborigines exploited fire to remake their environment into something more usable, so Stephen Pyne exploits fire to transform the landscape of history into something more accessible, to use its transmuting power to extract new meaning out of familiar events. Pyne traces the impact of fire, from its initial influence on the evolving vegetation of the new continent, through its use by the Aborigines and the subsequent European settlers, to the holocaust of February 1983 known as Ash Wednesday, and he shows us that the dynamic nature of fire has made it a most powerful environmental determinant in Australia, shaping both its social and natural histories. In his critically acclaimed study of Antarctica, The Ice, Pyne explored the myriad dimensions of the cold continent; now Burning Bush offers us an equally absorbing examination of a continent informed by fire.
