Biological Invasions in South Africa by Brian W. van Wilgen,John Measey,David M. Richardson,John R. Wilson,Tsungai A. Zengeya Pdf
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.
Biological Control in IPM Systems in Africa by P. Neuenschwander,C. Borgemeister,J. Langewald Pdf
Annotation. Biological control has made a major contribution to integrated pest management (IPM) in Africa, but its documentation has been scattered and often under-reported. This book provides a review of the most important studies, including not only successes, but also on-going challenges. The focus is on arthropod pests and weeds, but diseases are also covered where significant. In 24 chapters, case studies and promising research results are presented that cover biocontrol by naturally occurring agents, by exotic agents or by seasonal manipulation. This book provides a valuable resource for scientists worldwide. It is particularly useful for pest control professionals working in Africa.
The Long-Term Fate of Invasive Species by Arne Jernelöv Pdf
This book examines the long-term fate of invasive species by detailing examples of invaders from different zoological and botanical taxa from various places around the world. Readers will discover what happened, after a century or so, to 'classical' invaders like rabbits in Australia, house sparrows in North America, minks in Europe and water hyacinths in Africa and Asia. Chapters presented in the book focus on eighteen species in the form of in-depth case studies including: earthworms, zebra mussels, Canadian water weed, Himalayan balsam, house sparrows, rabbits, crayfish plague, Colorado beetles, water hyacinths, starlings, Argentine ant, Dutch elm disease, American mink, cane toad, raccoons, Canadian beavers, African killer bees and warty comb jelly. Invaded areas described are in Africa, Asia, Australia, Europe, North America, Pacific islands, and South America. Readers will get some ideas about the likely future of current invaders from the fate of old ones. This book is intended for undergraduates studying environmental sciences, researchers and members of environmental NGO's.
Invasive Alien Species by Thammineni Pullaiah,Michael R. Ielmini Pdf
INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.

Agricultural Intensification, Environmental Conservation, Conflict and Co-Existence at Lake Naivasha, Kenya by Anonim Pdf
This interdisciplinary volume provides a comprehensive and rich analysis of the century-long socio-ecological transformation of Lake Naivasha, Kenya. Major globalised processes of agricultural intensification, biodiversity conservation efforts, and natural-resource extraction have simultaneously manifested themselves in this one location. These processes have roots in the colonial period and have intensified in the past decades, after the establishment of the cut-flower industry and the geothermal-energy industry. The chapters in this volume exemplify the multiple, intertwined socio-environmental crises that consequently have played out in Naivasha in the past and the present, and that continue to shape its future.

Historical Dictionary of Malawi by Owen J. M. Kalinga Pdf
Malawi, established as the British protectorate of Nyasaland in 1891, gained its independence in 1964 and moved immediately into three decades of one-party rule. Since the mid-1990s, however, the country has held multi-party elections, as directed by its constitution, and President Bingu wa Mutharika is currently serving his second term. The fourth edition of the Historical Dictionary of Malawi, now newly expanded and updated, covers a wide range of areas in Malawi history, including the rise and fall of state systems, religious and socio-political movements, the economy, environment, transportation, war, disease, and natural sciences. Author Owen J. M. Kalinga charts developments from pre-history to the post-Banda Malawi, from Tom Bokwito to James Sangala, and from the UMCA mission at Magomero to the second term of Bingu wa Mutharika's presidency, paying particular attention to the individuals, groups, communities, and forces that have molded this South African country. The dictionary itself contains over 1,000 cross-referenced entries on crucial aspects of Malawi history, and it is the most extensive single-volume reference work on Malawi available. In addition to the dictionary entries, Kalinga provides a chronology containing important dates and events and an informative bibliographical section organized by subject. The final part of the bibliography gives the reader a list of current and obsolete newspapers and periodicals related to Malawi, an ideal resource for further research. This newly updated edition is an excellent access point for students, researchers, and anyone wanting to know more about Malawi.
