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.

Geophysics is a comparatively young science which only evolved as a distinct discipline during the 19th century. However, its phenomena (like earthquakes, tsunamis, volcanic eruptions and lightning) had been objects of fear, curiosity and speculation since ancient times. In this book, Johan de Beer and his research team reveal that geophysical activity in South Africa can be traced back to as early as 1488. This is a truly astonishing revelation which deserves to be firmly entrenched as part of the country?s proud history. The book also discusses the history and formation of South African geophysical institutions that made a huge and seldom acknowledged contribution to the technological development of southern Africa.

Climate change affects us all, but it can be a confusing business. In this book, three scientists with several decades of experience in assessing the potential effects of climate change for the southern African region share their insights. Complex issues are dealt with in plain language, without oversimplification and with attention to accuracy. The material is up-to-date as is possible in such a fast-developing field. Climate Change: Briefings from Southern Africa takes the form of 55 'frequently-asked' questions', each with a brief and clear reply. It is illustrated with colour diagrams and photographs, and examples are tailored to the regional context. The authors' introduction provides an overview of current national and international policies aimed at regulating climate change. The content is divided into four sections, which take the reader through the science of how climate system works; the projected impacts in southern Africa during the twenty-first century; what this means for the South African economy and society; and what can be done to avoid harm. The briefings can be read alone or in sequence. The year 2015 is regarded as a watershed for global climate change action if a global average temperature rise of more than two degrees abbove the pre-Industrial level is to be avoided. This book provides compelling evidence that the impact on agriculture, fisheries, water resources, human health, plants and animals as well as sea levels will be dangerous. However, the book ends on a positive note by offering advice on how the world can avoid such bleak outcomes, while allowing a good life for all. The volume is aimed at interested non-scientists, including business people, decision-makers, ordinary citizens and students
