Veld is 'n lewensbelangrike natuurlike hulpbron vir ons aardse bestaan. Sowat 80% van ons mooi land bestaan uit veld. Die grootste deel daarvan word vir vee- en wildboerdery asook vir bewaring van biodiversiteit en vir ontspanning gebruik. Goeie veldbestuur is nodig om grondagteruitgang te stuit en om volhoubare voedselproduksie en bewaring van biodiversiteit te verseker. Maar goeie veldbestuur berus op 'n goeie kennis van ekologiese beginsels en veldbestuurspraktyke, iets wat baie grondgebruikers nie beskore was om te verkry nie. Die boek poog om die nodige kennis te verskaf om grondgebruikers te help om die grond in hul sorg doeltreffend te bestuur - inderdaad 'n reuseverantwoordelikheid. Die insluiting van meer as 380 foto's en illustrasies en die gebruik van maklik verstaanbare taal in Veldbestuur - Beginsels en Praktyke is daarop gemik om die taamlik tegniese onderwerp te vereenvoudig.

In 1517, the Ottoman Sultan Selim "the Grim" conquered Egypt and brought his empire for the first time in history into direct contact with the trading world of the Indian Ocean. During the decades that followed, the Ottomans became progressively more engaged in the affairs of this vast and previously unfamiliar region, eventually to the point of launching a systematic ideological, military and commercial challenge to the Portuguese Empire, their main rival for control of the lucrative trade routes of maritime Asia.
The Ottoman Age of Exploration is the first comprehensive historical account of this century-long struggle for global dominance, a struggle that raged from the shores of the Mediterranean to the Straits of Malacca, and from the interior of Africa to the steppes of Central Asia. Based on extensive research in the archives of Turkey and Portugal, as well as materials written on three continents and in a half dozen languages, it presents an unprecedented picture of the global reach of the Ottoman state during the sixteenth century. It does so through a dramatic recounting of the lives of sultans and viziers, spies, corsairs, soldiers-of-fortune, and women from the imperial harem. Challenging traditional narratives of Western dominance, it argues that the Ottomans were not only active participants in the Age of Exploration, but ultimately bested the Portuguese in the game of global politics by using sea power, dynastic prestige, and commercial savoir faire to create their own imperial dominion throughout the Indian Ocean.

A year-round escape for one million annual tourists, Catalina Island is gaining popularity as a world-class eco-destination. Eighty-eight percent of the island is under the watch of the Catalina Island Conservancy, which preserves, manages and restores the island's unique wild lands. Bison, foxes and bald eagles are its best-known inhabitants, but Catalina is home to more than sixty other animal and plant species that exist nowhere else on earth. And they are all within the boundaries of one of the world's most populous regions: Los Angeles County. Biologists Frank Hein and Carlos de la Rosa present a highly enjoyable tour through the fascinating origins, mysterious quirks and ecological victories of one of the West Coast's most remarkable places.

Wick will chronicle the history of this multifaceted river, from canals, to the fishing industry, to transportation.

Aims and Scope Growing social and economic needs exert major pressures on landscapes, challenging preserved landscape values and the regional significance of places. As a result, the scope oflandscape management has broadened and diversifiedin response to international calls for greater landscape protection, and to existing and new challenges, such as thoserelating to climate change adaptation and ecosystem services. Within this context, landscape impact assessment and more in general landscape planning have been regarded as effective mechanisms for promoting and, at the same time, as the basis of sustainable landscape development. Set within the European context, thisbookaims to provide acontemporary review of landscape impact assessment theory and practice, looking at both the project and planning level. It coversthe overall process, content and scope of landscape impact assessment, including the main principles for good practice. Thisbook also provides guidance on a rangeof methods and techniques for different aspects of landscape impact assessment and public participation needs; and explains the advantages of close co-ordination between landscape impact assessment and landscape planning, especially in land use planning. Finally, a selection of case studies reviewing different aspects and practices of landscape impact assessment are reviewed. This book will be of interest to professionals involved in the day-to-day application of landscape impact assessment, as well as scholars and teachers working in the broad area of landscape planning andmanagement. The authors of thisbook have vast experiencein the research and practice of environmental assessment and landscape management.

This book will explore our forests as the most readily available and renewable source of carbon as well as the building block of chemicals, plastics, and pharmaceuticals as the next 100 years gradually push consumers toward alternate sources of chemicals. Meeting these needs from trees requires that new chemistry be developed so that plant materials is converted to commodity chemicals. This focused discussion on ongoing global efforts at creativity using forest and biomass based renewable materials will include six different mechanisms for bringing about change on this very innovative topic.

""Waves in Ocean Engineering"" covers the whole field of wave studies of interest to applied oceanographers and ocean engineers. It has considerable relevance to coastal engineering.
The book is split into 12 sections, the first of which is devoted to the practical applications of wave studies and to the history of wave research. The rest of the book covers the measurement of waves, including remote sensing; the analysis and interpretation of wave data; estimating the properties of the extreme "Design Wave," as well as of the generality of waves for fatigue calculations; waves in finite depth, wave generation by wind and wave forecasting models; non-linear effects, and errors and uncertainties in wave data.

In the first decade of the 21st century, five rising powers (Brazil, Russia, India, China, and South Africa) formed an exclusive and informal international club, the BRICS. Although neither revolutionaries nor extreme revisionists, the BRICS perceive an ongoing global power shift and contest the West's pretensions to permanent stewardship of the existing economic order. Together they have exercised collective financial statecraft, employing their expanding financial and monetary capabilities for the purpose of achieving larger foreign policy goals. This volume examines the forms and strategies of such collective financial statecraft, and the motivations of each individual government for collaborating through the BRICS club. Their cooperative financial statecraft takes various forms, ranging from pressure for "inside reforms" of either multilateral institutions or global markets, to "outside options" exercised through creating new multilateral institutions or jointly pushing for new realities in international financial markets. To the surprise of many observers, the joint actions of the BRICS are largely successful. Although each member has its unique rationale for collaboration, the largest member, China, controls resources that permit it the greatest influence in intra-club decision-making. The BRICS cooperate due to both common aversions (for example, resentment over being perennial junior partners in global economic and financial governance and resistance to infringements on their autonomy due to U.S. dollar dominance and financial power) and common interests (such as obtaining greater voice in international institutions, as the IMF). The group seeks reforms, influence, and enhanced leadership roles within the liberal capitalist global system. Where blocked, they experiment with parallel multilateral institutions in which they are the dominant rule-makers. The future of the BRICS depends not only on their bargaining power and adjustment to market players, but also on their ability to overcome domestic impediments to sustainable economic growth, the basis for their international influence.

Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million
years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth.
The first edition of McElhinny's book was heralded as a "classic and definitive text." It thoroughly discussed the theory of geomagnetism, the geologic
reversals of the Earth's magnetic field, and the shifting of magnetic poles. In the 25 years since the highly successful first edition of Palaeomagnetism and Plate Tectonics (Cambridge, 1973) the many advances in the concepts, methodology, and insights into paleomagnetism warrant this new treatment. This completely updated and revised edition of Paleomagnetism: Continents and Oceans will be a welcome resource for a broad audience of earth scientists as well as laypeople curious about magnetism, paleogeography, geology, and plate tectonics.
Because the book is intended for a wide audience of geologists, geophysicists, and oceanographers, it balances the mathematical and descriptive aspects of each topic.
* Details the theory and methodology of rock magnetism, with particular emphasis onintrepreting crustal movements from continental and oceanic measurements
* Outlines Earth history for the past 1000 million years, from the Rodinia super-continent through its breakup and the formation of Gondwana to the formation and breakup of Pangea and the amalgamation of Eurasia
* Provides a comprehensive treatment of oceanic paleomagnetism
* Provides a set of color pateogeographic maps covering the past 250 million years
* Written by two internationally recognized experts in the field

European explorers were captivated by the seemingly endless bounty of natural resources on Cape Cod Bay. One Englishman declared that the codfish were so thick one "could" walk on their backs. Early settlers quickly learned how to harness the bay's resources and excelled at shore whaling, shipping and salt making. But as these new industries flourished, the native Wampanoag, who helped the fledgling colony to take root, nearly vanished. Author Theresa Mitchell Barbo's skillful narrative weaves together the natural and cultural histories of the bay, highlighting some of the region's diverse milestones- from the drafting of the Mayflower Compact in 1620 to the establishment of the Pilgrim Nuclear Power Plant 350 years later. "Cape Cod Bay: A History of Salt & Sea" inspires new appreciation for this storied and stunning seascape, and underscores the importance of new efforts to preserve the bay's unique ecosystem.

Appreciating that coastal areas are under threat from misuse and overuse worldwide, this book reviews the need for marine conservation, summarizes general measures for ocean and coastal conservation, and explains the rationale for establishing marine protected areas.

This book brings together current thought on several aspects of the use of pesticides in and around homes, schools and workplaces. The book addresses several parts of the process, from the discovery and development of new active ingredients, their formulation, use, longevity, environmental fate and human exposure.

'Seawater' has been substantially updated in this second edition to take account of recent developments in marine science. Sections dealing with difficult physical and chemical concepts have been developed on the basis of feedback from the first edition, making this an ideal learning tool for oceanography students.

Chapter 1 summarizes the special properties of water and the role of the oceans in the hydraulic cycle. The distribution of temperature and salinity in the oceans and how they influence water density and movements is then discussed. Light and sound in seawater are considered next, along with some uses of acoustics. These are followed by an examination of the composition and behaviour of dissolved constituents, including such topics as residence times, the control of pH, and redox relationships.
Finally, the history of seawater and its role in global cycles is reviewed, with special reference to climatic change and the CO2 problem.

In Quality Peace, leading peace researcher Peter Wallensteen offers a broad analysis of peacebuilding, isolating what does and not work when settling conflicts. The book uses statistical analysis to compare two war outcomes-negotiated settlement and victory- in the post-Cold War era. Wallensteen finds that if peace is to last, three conditions must be met: a losing party must retain its dignity; security and the rule of law must be ensured for all; and the time horizon for the settlement must be long enough to ensure a sense of normalcy. Wallensteen breaks down the components of all of these conditions and applies them to interstate conflicts, civil wars in which rebels are aiming to take over the entire state, and separatist rebellions. He also delves into the issue of world order and the significance of major power relations for local peace efforts. Thus, the work provides a remarkable understanding of how different types of war outcomes deal with post-war conditions. Sharply argued and comprehensive, Quality Peace will invigorate peace research and stimulate peace practice, becoming an authoritative work in the field.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes readers across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a twenty-five-foot tidal bore that crashes eighty miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation; and in Panama and Venice, he delves into how the threat of sea level rise is changing human culture the very old and very new. Tides combines lyrical prose, colorful adventure travel, and provocative scientific inquiry into the elemental, mysterious paradox that keeps our planet's waters in constant motion. Photographs, scientific figures, line drawings, and sixteen color photos dramatically illustrate this engaging, expert tour of the tides.

Could low-level exposure to polluting chemicals be analogous to exercise-a beneficial source of stress that strengthens the body? Some scientists studying the phenomenon of hormesis (beneficial or stimulatory effects caused by low-dose exposure to toxic substances) claim that that this may be the case. Is A Little Pollution Good For You? critically examines the current evidence for hormesis. In the process, it highlights the range of methodological and interpretive judgments involved in environmental research: choices about what questions to ask and how to study them, decisions about how to categorize and describe new information, judgments about how to interpret and evaluate ambiguous evidence, and questions about how to formulate public policy in response to debated scientific findings. The book also uncovers the ways that interest groups with deep pockets attempt to influence these scientific judgments for their benefit. Several chapters suggest ways to counter these influences and incorporate a broader array of societal values in environmental research: (1) moving beyond conflict-of-interest policies to develop new ways of safeguarding academic research from potential biases; (2) creating deliberative forums in which multiple stakeholders can discuss the judgments involved in policy-relevant research; and (3) developing ethical guidelines that can assist scientific experts in disseminating debated and controversial phenomena to the public. Kevin C. Elliott illustrates these strategies in the hormesis case, as well as in two additional case studies involving contemporary environmental research: endocrine disruption and multiple chemical sensitivity. This book should be of interest to a wide variety of readers, including scientists, philosophers, policy makers, environmental ethicists and activists, research ethicists, industry leaders, and concerned citizens. "This is a timely, well-researched and compelling book .Elliott admirably combines insights and strategies from philosophy of science with those of applied ethics to carefully analyze contemporary science and science policy around pollutants and human health. There is a growing interest in the philosophy of science community in bringing the work of philosophers to bear on contemporary social issues. This book stands out as a model for how to do just that." - Sandra D. Mitchell, Philosophy, University of Pittsburgh Is A Little Pollution Good For You? is a wonderfully clear and insightful book dealing with the interplay between social values and economic and political interests in scientific research. He articulates an account of how societal values should and should not enter into science and illustrates his views with an extended discussion of research on hormesis-the hypothesis that chemicals that are toxic at high doses may be benign or even beneficial at low doses. The chemical industry has a strong financial interest in promoting scientific acceptance of hormesis, as this could convince regulatory agencies to loosen up restrictions on allowable exposures to pesticides and other chemicals. Elliott argues that because scientists have an obligation to minimize the harmful effects of their research, they must be mindful of the social context of their work and how it may be interpreted and applied by private companies or interest groups, to the potential detriment of public and environmental health. Elliott's book is a must read for researchers, scholars, and students who are interested in the relationship between science, industry, and society." - David B. Resnik, National Institute of Environmental Health Sciences, National Institutes of Health, author of Playing Politics With Science: Balancing Scientific Independence And Government

We are becoming increasingly aware of the overwhelming pollution of our limited water resources on this planet. And while many contaminants originate from Mother Earth, most water pollution comes as a direct result of anthropogenic activities. This problem has become so immense that it threatens the future of all humanity. If effective measures to reduce and/or remediate water pollution and its sources are not found, it is estimated by UN that 2.7 billion people will face water shortage by 2025 as opposed to 1.2 billion people who do not have access to clean drinking water now. Therefore, development of novel green technologies to address this major problem represents a priority of the highest importance. This book discusses green chemistry and other novel solutions to the water pollution problems which includes some interesting applications of nanoparticles. Novel Solutions to Water Pollution is a useful and informative text for those engaged in issues of water quality and water pollution remediation at operational, administrative, academic, or regulatory levels.

In this volume, Stephen M. Gardiner and David A. Weisbach present arguments for and against the relevance of ethics to global climate policy. Gardiner argues that climate change is fundamentally an ethical issue, since it is an early instance of a distinctive challenge to ethical action (the perfect moral storm), and ethical concerns (such as with justice, rights, political legitimacy, community and humanity's relationship to nature) are at the heart of many of the decisions that need to be made. Consequently, climate policy that ignores ethics is at risk of "solving " the wrong problem, perhaps even to the extreme of endorsing forms of climate extortion. This is especially true of policy based on narrow forms of economic self-interest. By contrast, Weisbach argues that existing ethical theories are not well suited to addressing climate change. As applied to climate change, existing ethical theories suffer from internal logical problems and suggest infeasible strategies. Rather than following failed theories or waiting indefinitely for new and better ones, Weisbach argues that central motivation for climate policy is straightforward: it is in their common interest for people and nations to agree to policies that dramatically reduce emissions to prevent terrible harms.
