These photographs of the transition to self-rule of the former Portuguese colonies, were captured by photographers of the Argus Africa News Service, "a small, highly professional South African agency. These have been compiled here by its then editor, Wilf Nussey, who wrote the accompanying text." -- Back cover.
Exploring the cultural politics of Cuba's epic military engagement in the Angolan civil war, this book narrates the transformation of Cuban national identity from Latin African to Caribbean through the experience of internationalism in Angola.
"Helen Kitchen has drawn on the expertise of a trio of respected U.S., British, and West German analysts to assist in what she does best--explaining the diversity and complexity of African political dynamics. As this book ably demonstrates, U.S. policy choices will go awry if they are made on the assumption that Africa is a collection of immutably labeled ideological boxes." David D. Newsom, Director of the Institute for the Study of Diplomacy, Georgetown University
Integrated Assessment of Scale Impacts of Watershed Interventions is the outcome of a multi-disciplinary research team of social scientists, hydrologists (groundwater and surface water), modellers; and bio-physical scientists who have worked together over five years to develop an integrated model of the sustainability of biophysical, economic and social impacts of watersheds. Impacts of watershed interventions are assessed at upstream, mid-stream and downstream locations of two hydrological units that are characterised with differential bio-physical attributes. The editors propose that watershed interventions, when integrated with hydro-geology and bio-physical aspects, have greater influence on the resilience of the socio-ecological system. This book takes these aspects in to consideration and in the process provides insights in to watershed design and implementation. Integrates hydrogeology, bio-physical, and socioeconomic aspects of watersheds in a hydrological context Provides a comprehensive understanding of the impacts of watershed interventions Assesses the role of watershed interventions in enhancing household resilience Provides hydrological and socio-economic methodologies for design of sustainble watershed interventions including scale and institutional arrangements for implementing and sustaining watershed interventions

With the continuing increase in population, more people are sharing the finite resources of the urban watershed, resulting in new and increasingly complex interactions between humans and the environment. Environmental contamination is a chronic problem—and an expensive one. In urban areas, water and soil contamination poses a threat to public health and has implications for future development. Taking an interdisciplinary approach, Urban Watersheds: Geology, Contamination, and Sustainable Development offers a framework for those working to improve the urban environment and create sustainable urban watersheds. The book presents over 20 years of research and professional practice on urban watersheds from the fields of environmental geology, geochemistry, risk analysis, hydrology, and urban planning. The geological characteristics of urbanized watersheds along with the properties of their common contaminants are integrated to assess risk factors for soil, groundwater, and air. With a framework rooted in scientific knowledge, the authors demonstrate the benefits of scientifically informed planning and decision making, offering guidelines to improve watershed management practices as well as urban development and redevelopment practices. Suitable for use as a textbook and as a professional practice reference, the book includes case studies on successful and unsuccessful approaches to contaminant remediation as well as practical methods for environmental risk assessment. PowerPoint® presentations of selected portions of the book are available with qualifying course adoption.
The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today’s pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970’s studies of atmospheric deposition; the 1980’s research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990’s investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century’s research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who’s who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.
This new edition is a major revision of the popular introductory reference on hydrology and watershed management principles, methods, and applications. The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use watersheds. Case studies and examples throughout the book show practical ways to use web sites and the Internet to acquire data, update methods and models, and apply the latest technologies to issues of land and water use and climate variability and change.
With contributions from a wide array of economists, ecologists, and government agency professionals, Economics and Ecological Risk Assessment: Applications to Watershed Management provides a multidisciplinary approach to environmental decision-making at a watershed level. It introduces the fields of ecological risk assessment (ERA) and economic analysis and discusses their application to the practice of watershed management. The book presents a general framework for the integration of ERA and economic analysis to improve environmental management in a diversity of watersheds. Focusing on real-world decisions, this book describes studies conducted in six U.S. watersheds where both ecological and economic analyses were needed. Decision contexts for these studies include negotiations to satisfy Endangered Species Act requirements, natural resource damage assessment, Clean Water Act permitting, and community development planning. The success of ecological-economic integration in each study, and the contribution to decision making, is critically examined.
With $2 billion spent annually on stream restoration worldwide, there is a pressing need for guidance in this area, but until now, there was no comprehensive text on the subject. Filling that void, this unique text covers both new and existing information following a stepwise approach on theory, planning, implementation, and evaluation methods for the restoration of stream habitats. Comprehensively illustrated with case studies from around the world, Stream and Watershed Restoration provides a systematic approach to restoration programs suitable for graduate and upper-level undergraduate courses on stream or watershed restoration or as a reference for restoration practitioners and fisheries scientists. Part of the Advancing River Restoration and Management Series. Additional resources for this book can be found at: www.wiley.com/go/roni/streamrestoration.
