Описание: This book presents various aspects of agroforestry research and development, as well as the latest trends in degraded landscape management. Over the last four decades, agroforestry research (particularly on degraded landscapes) has evolved into an essential problem-solving science, e.g.
Описание: Agroforestry systems (AFS) are becoming increasingly relevant worldwide as society has come to recognize their multiple roles and services: biodiversity conservation, carbon sequestration, adaptation and mitigation of climate change, restoration of degraded ecosystems, and tools for rural development. This book summarizes advances in agroforestry research and practice and raises questions as to the effectiveness of AFS to solve the development and environmental challenges the world presents us today. Currently AFS are considered to be a land use that can achieve a compromise among productive and environmental functions. Apparently, AFS can play a significant role in rural development even in the most challenging socioeconomic and ecological conditions, but still there is a lot of work to do to reach these goals. Considerable funding is spent in projects directed to enhancing productivity and sustainability of smallholders forestry and agroforestry practices. These projects and programs face many questions and challenges related to the integration of traditional knowledge to promote the most suitable systems for each situation; access to markets for AFS products, and scaling up of successful AFS. These complex questions need innovative approaches from varying perspectives and knowledge bases. This book gathers fresh and novel contributions from a set of Yale University researchers and associates who intend to provide alternative and sometimes departing insights into these pressing questions. The book focuses on the functions that AFS can provide when well designed and implemented: their role in rural development as they can improve food security and sovereignty and contribute to provision of energy needs to the smallholders; and their environmental functions: contribution to biodiversity conservation, to increased connectivity of fragmented landscapes, and adaptation and mitigation of climate change. The chapters present conceptual aspects and case studies ranging from traditional to more modern approaches, from tropical as well as from temperate regions of the world, with examples of the AFS functions mentioned above.
Описание: Focuses on the issue of how best to design, manage and operate water control facilities so as to meet ecological and environmental as well as economic objectives. This book describes case examples, covering the restoration needs and activities taking place in river basins in Central Asia, Eastern and Western Europe and North America.
Описание: In the continued quest for increased economic benefits from our water resources, numerous structures and operating policies for controlling the river flow have been built and implemented. These structures and associated operating policies can facilitate navigation; they can provide greater quantities of reliable water supplies to meet agricultural, industrial and municipal water demands; they can generate hydroelectric power and energy; and they can provide increased flood protection, recreation, and other benefits. Over the past half-century we have converted many of our rivers into engineered waterways. These straightened, often periodically dredged, engineered rivers are complete with dikes, reservoirs, weirs, and diversion canals. All this engineering has enhanced economic development. However, as rivers and their floodplains become stressed from the excessive use and misuse of their resources, their contribution to economic development can be threatened. Evidence of economic and ecological degradation, especially in relatively large river systems such as the Danube, the Mississippi, the Rhine, and the Volga, has increased our appreciation of beneficial roles natural aquatic and terrestrial ecosystems play in water quantity and quality management. We have recognized the need to pay more attention to letting nature help us regulate water quantity and quality rather than working against nature and its variabilities and uncertainties. Today there are efforts underway in many developed river basins to 'de- engineer' or return these straightened and controlled rivers to a more natural state.

Описание: Agroforestry has come of age during the past three decades. While it is true that the tropics, compared to the temperate regions, have a wider array of agroforestry systems and hold greater promise for potential agroforestry interventions, it is also true that agroforestry has several opportunities in the temperate regions too.
Описание: Comprises a selection of contributions presented at a workshop held in Montpellier in 1997. The two main objectives of the workshop were to bring together what is understood about the processes underlying agroforestry practice, and to provide a forum to explore models and modelling approaches.

Описание: This book gathers and classifies available information into different system ecologies, problems and solutions, and converges them into a policy support study of India, which has long practiced agroforestry and helped to foster scientific developments.
Описание: This volume elucidates new aspects of the problems faced in utilization of salt-tolerant plants as a resource for livestock. It also explores the roles of halophytes in the rehabilitation of degraded lands, especially in the world`s drier regions.
