Available in PDF, EPUB and Kindle. Book excerpt: This innovative interdisciplinary study focuses on the history, science, and policy of tree planting and water conservation in South Africa. South Africa’s forestry sector has sat—often controversially—at the crossroads of policy and scientific debates regarding water conservation, economic development, and biodiversity protection. Bennett and Kruger show how debates about the hydrological impact of exotic tree planting in South Africa shaped the development of modern scientific ideas and state policies relating to timber plantations, water conservation, invasive species control, and biodiversity management within South Africa as well as elsewhere in the world. Forestry and Water Conservation in South Africa shows how scientific research on the impact of exotic and native vegetation led to the development of a comprehensive national policy for conserving water, producing timber, and protecting indigenous species from invasive alien plants. Policies and laws relating to forests and water began to change in the late 1980s and early 1990s as a result of political and administrative changes within South Africa. This book suggests that the country’s contemporary policies towards timber plantations, guided by the National Water Act of 1998, need to be reconsidered in light of the authors’ findings. Bennett and Kruger also call for more interdisciplinary research and greater emphasis on integrated policies and management plans for forestry, invasive alien plants, water conservation, and biodiversity preservation.

Book excerpt: It has become clear that soil water repellency is much more wide-spread than formerly thought. Water repellency has been reported in most continents of the world for varying land uses and climatic conditions. Soil water repellency often leads to severe runoff and erosion, rapid leaching of surface-applied agrichemicals, and losses of water and nutrient availability for crops. At present, no optimum management strategies exist for water repellent soils, focusing on minimizing environmental risks while maintaining crop production. The book starts with a historical overview of water repellency research, followed by seven thematic sections covering 26 research chapters. The first section discusses the origin, the second the assessment, and the third the occurrence and hydrological implications of soil water repellency. The fourth section is devoted to the effect of fire on water repellency, section five deals with the physics and modeling of flow and transport in water repellent soils, section six presents amelioration techniques and farming strategies to combat soil water repellency, and section seven concludes the book with an extensive bibliography on soil water repellency.

This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists are increasingly being drawn into the task of addressing problems of environmental degradation. They are expected to find solutions that will lead to sustainable resource use throughout the world. In doing so, the robustness of the science becomes increasingly important, and the problem of extrapolating the results of research conducted within what is usually a relatively limited geographical scope is increasingly highlighted. One approach to developing a globally robust ecology involves more or less formal intercontinental comparative studies, usually focused on the question of ecological convergence. These studies are directed at testing the prediction that similar physical and other environmental factors in different parts of the world, through their selective influences, will give rise to ecosystems which share com mon structural and functional features. Should this be true, the predictive power of ecology developed within such a framework should be sufficient to solve similar problems elsewhere in such biomes. There is a long history of such an approach in mediterranean type ecosystems, documented in a series of volumes and their accompanying scientific papers beginning with that of Di Castri and Mooney (1973).

Download or read book Biological Invasions in South Africa written by Brian W. van Wilgen and published by Springer Nature. This book was released on 2020-03-10 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Book excerpt: 'Blue Revolution upturns some environmental applecarts - not for the hell of it, but so we can manage our environment better.' Fred Pearce, New Scientist This updated and revised edition of The Blue Revolution provides further evidence of the need to integrate land management decision-making into the process of integrated water resources management. It presents the key issues involved in finding the balance between the competing demands for land and water: for food and other forms of economic production, for sustaining livelihoods, and for conservation, amenity, recreation and the requirements of the environment. It also advocates the means and methodologies for addressing them. A new chapter, 'Policies, Power and Perversity,' describes the perverse outcomes that can result from present, often myth-based, land and water policies which do not consider these land and water interactions. New research and case studies involving ILWRM concepts are presented for the Panama Canal catchments and in relation to afforestation proposals for the UK Midlands.

Available in PDF, EPUB and Kindle. Book excerpt: The environmental movement is plagued by pessimism. And that’s not unreasonable: with so many complicated, seemingly intractable problems facing the planet, coupled with a need to convince people of the dangers we face, it’s hard not to focus on the negative But that paints an unbalanced—and overly disheartening—picture of what’s going on with environmental stewardship today. There are success stories, and Our Once and Future Planet delivers a fascinating account of one of the most impressive areas of current environmental experimentation and innovation: ecological restoration. Veteran investigative reporter Paddy Woodworth has spent years traveling the globe and talking with people—scientists, politicians, and ordinary citizens—who are working on the front lines of the battle against environmental degradation. At sites ranging from Mexico to New Zealand and Chicago to Cape Town, Woodworth shows us the striking successes (and a few humbling failures) of groups that are attempting to use cutting-edge science to restore blighted, polluted, and otherwise troubled landscapes to states of ecological health—and, in some of the most controversial cases, to particular moments in historical time, before widespread human intervention. His firsthand field reports and interviews with participants reveal the promise, power, and limitations of restoration. Ecological restoration alone won’t solve the myriad problems facing our environment. But Our Once and Future Planet demonstrates the role it can play, and the hope, inspiration, and new knowledge that can come from saving even one small patch of earth.

This book was released on 2012-12-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a stimulating tale of the interplay of observation, experimentation, working hypotheses, tentative conclusions, niggling and weightier doubts and great aspirations, on the part of some score of students, on varied ecological and other aspects of the regime and role of fire in relevant biomes and ecosystem- mainly in South Africa - and on other pertinent features of fire ecology. The impressive contents is a tribute to conveners and authors alike. One can expect a profound range and depth ofinvestigation and interpretation, a closeknit fabric of knowledge, delicately interwoven with wisdom, an exposition and quintessence of information. Admipable is the collective vision responsible for selecting appropriate topics: the wide sweeps of the brush picturing the nature of the biomes; ably describing the fire regimes - whether in grassland, savanna, fynbos or forest; skillfully defining the effects of such regimes - according to ecosystem - upon aerial and edaphic factors of the habitat, upon constituent biota, individually, specifically and as a biotic community; elucidating the basic implications in the structure and dynamics of the plant aspect of that community ... and unravelling to some degree the tangled knot of the conservation and dissipation of moisture and nutrients. Moreover, gratitude is owed for efforts exerted to understand the interplay of fire and faunal behaviour and dynamics as well as composition, together with the principle of adaptive responses of organisms of diverse kinds.

Book excerpt: Cape Town's iconic Table Mountain and the surrounding peninsula has been a crucible for attempts to integrate the social and ecological dimensions of wild fire. This environmental history of humans and wildfire outlines these interactions from the practices of Khoikhoi herders to the conflagrations of January 2000. The region's unique, famously diverse fynbos vegetation has been transformed since European colonial settlement, through urbanisation and biological modifications, both intentional (forestry) and unintentional (biological invasions). In all the diverse visions people have formed for Table Mountain, aesthetic and utilitarian, fire has been regarded as a central problem. This book shows how scientific understandings of fire in fynbos developed slowly in the face of strong prejudices. Human impacts were intensified in the twentieth century, which provides the temporal focus for the book. The disjunctures between popular perception, expert knowledge, policy and management are explored, and the book supplements existing short-term scientific data with proxies on fire incidence trends recovered from historical records.
