This title was first published in 2003. There has been increasing recognition around the world that wetlands are fragile ecosystems which require sensitive and sustainable management if they are to continue to provide their range of functions and benefits. These functions and benefits, which include contributions to food security and environmental regulation, play a critical role in sustaining rural livelihoods in many developing countries. Drawing upon research carried out in the area, this book identifies and discusses the importance of wetlands to local communities in south-west Ethiopia, and in particular, how indigenous wetland management practices contribute to sustainable wetland use. As the basis of wetland management, particular attention is paid to the role of Indigenous Knowledge Systems, and how knowledge of wetland functioning is acquired, disseminated, developed and applied by local communities in their wetland management strategies. Critically, this community knowledge is examined in the context of scientific data, specifically that obtained from a wetland hydrology monitoring programme, thereby drawing attention to the strengths and weaknesses of both systems. This has major implications not only for the ways in which wetlands and other natural resources are managed at the local level, but also for the wider rural development strategies of governments and non-governmental organizations.

Indigenous Knowledge (IK) reviews cutting-edge research and links theory with practice to further our understanding of this important approach's contribution to natural resource management. It addresses IK's potential in solving issues such as coping with change, ensuring global food supply for a growing population, reversing environmental degradation and promoting sustainable practices. It is increasingly recognised that IK, which has featured centrally in resource management for millennia, should play a significant part in today's programmes that seek to increase land productivity and food security while ensuring environmental conservation. An invaluable resource for researchers and postgraduate students in environmental science and natural resources management, this book is also an informative read for development practitioners and undergraduates in agriculture, forestry, geography, anthropology and environmental studies.

Fundamentals of Tropical Freshwater Wetlands: From Ecology to Conservation Management is a practical guide and important tool for practitioners and educators interested in the ecology, conservation and management of wetlands in tropical/subtropical regions. The book is written in such a way that, in addition to scientists and managers, it is accessible to non-specialist readers. Organized into three themed sections and twenty-three chapters, this volume covers a variety of topics, exposing the reader to a full range of scientific, conservation and management issues. Each chapter has been written by specialists in the topic being presented. The book recognizes that wetland conservation, science and management are interlinked disciplines, and so it attempts to combine several perspectives to highlight the interdependence between the various professions that deal with issues in these environments. Within each chapter extensive cross-referencing is included, so as to help the reader link related aspects of the issues being discussed. - Contributed to by global experts in the field of tropical wetlands - Includes case studies and worked examples, enabling the reader to recreate the work already done - Focuses on tropical systems not available in any other book

In this book the authors argue for a paradigm shift in the way African wetlands are considered. Current policies and wetland management are too frequently underpinned by a perspective that views agriculture simply as a threat and disregards its important contribution to livelihoods. In rural areas where people are entrenched in poverty, wetlands (in particular wetland agriculture) have a critical role to play in supporting and developing peoples' livelihoods. Furthermore, as populations rise and climate change takes grip they will be increasingly important. The authors argue that an approach to wetland management that is much more people focused is required. That is an approach that instead of being concerned primarily with environmental outcomes is centred on livelihood outcomes supported by the sustainable use of natural wetland resources. The authors stress the need for Integrated Water Resource Management and landscape approaches to ensure sustainable use of wetlands throughout a river catchment and the need for wetland management interventions to engage with a wide range of stakeholders. They also assess the feasibility of creating incentives and value in wetlands to support sustainable use. Drawing on nine empirical case studies, this book highlights the different ways in which sustainable use of wetlands has been sought, each case focusing on specific issues about wetlands, agriculture and livelihoods.

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Wetland Habitatsis a practical manual that puts developments in the field of wetland restoration and conservation of diverse animal species into plain English, placing much of the more recent work in this field into a single, coherent and user-friendly framework. As with Planting Wetlands and Dams, the text explains the various approaches to and aspects of each problem, so that readers will be able to make informed decisions about managing wetlands on their own properties. Although the examples are drawn from a wide range of wetland animals, including some which aren't necessarily found in wetlands on private properties, the primary emphasis will be on species and aspects of management that are likely to be of most use to landholders with wetlands to be restored, or species in need of conservation. The plants and planting aspects of created wetlands and dams are dealt with in detail in the second edition of Planting Wetlands and Dams. Key features: * Reversing the effects of drainage, grazing, weirs, deteriorating water quality and associated algal problems, and allowing for global warming and sea level rises * Setting realistic targets for wetland restoration and longer-term goals for management * Understanding natural change in wetlands - seasonal, ecological and chemical

This comprehensive guide to wetland weeds covers both native and introduced species, ranging from minor or localised environmental problems to those that should not be tolerated in any situation. The author takes a pragmatic approach to weed control, recognising that some weeds may not be possible to eradicate, and emphasising the need to assess the extent and future potential of any infestation before taking action. Weed control should be planned in the context of the overall management goals for any type of wetland, the types of habitat weeds provide or overrun, and whether they can be replaced successfully with more appropriate plants. A range of strategies for controlling wetland weeds are considered, from containment actions to prevent the development of a soil seed bank to physical removal, and biological approaches from biocontrol to shading, overplanting and use of turbidity. The widespread use of chemical controls is also discussed, with the warning that these are often only a short-term cure and can cause more harm to aquatic ecosystems than the weeds they are holding at bay. More than 130 species of established weeds are included with information on their origins, nutrient responses, environmental effects, habitat values, prospects for containment or eradication, and even culinary uses. Other sections look at native plants as weeds, including a number of species of uncertain origins, and potential weeds still being legally sold through the aquarium and nursery trades.
