Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.

Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food sec

Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

This book contains case histories intended to show how societies and landscapes interact. The range of interest stretches from the small groups of the earliest Neolithic, through Bronze and Iron Age civilizations, to modern nation states. The coexistence is, of its very nature reciprocal, resulting in changes in both society and landscape. In some instances the adaptations may be judged successful in terms of human needs, but failure is common and even the successful cases are ephemeral when judged in the light of history. Comparisons and contrasts between the various cases can be made at various scales from global through inter-regional, to regional and smaller scales. At the global scale, all societies deal with major problems of climate change, sea-level rise, and with ubiquitous problems such as soil erosion and landscape degradation. Inter-regional differences bring out significant detail with one region suffering from drought when another suffers from widespread flooding. For example, desertification in North Africa and the Near East contrasts with the temperate countries of southern Europe where the landscape-effects of deforestation are more obvious. And China and Japan offer an interesting comparison from the standpoint of geological hazards to society - large, unpredictable and massively erosive rivers in the former case, volcanoes and accompanying earthquakes in the latter. Within the North African region localized climatic changes led to abandonment of some desertified areas with successful adjustments in others, with the ultimate evolution into the formative civilization of Egypt, the "Gift of the Nile". At a smaller scale it is instructive to compare the city-states of the Medieval and early Renaissance times that developed in the watershed of a single river, the Arno in Tuscany, and how Pisa, Siena and Florence developed and reached their golden periods at different times depending on their location with regard to proximity to the sea, to the main trunk of the river, or in the adjacent hills. Also noteworthy is the role of technology in opening up opportunities for a society. Consider the Netherlands and how its history has been formed by the technical problem of a populous society dealing with too much water, as an inexorably rising sea threatens their landscape; or the case of communities in Colorado trying to deal with too little water for farmers and domestic users, by bringing their supply over a mountain chain. These and others cases included in the book, provide evidence of the successes, near misses and outright failures that mark our ongoing relationship with landscape throughout the history of Homo sapiens. The hope is that compilations such as this will lead to a better understanding of the issue and provide us with knowledge valuable in planning a sustainable modus vivendi between humanity and landscape for as long as possible. Audience: The book will interest geomorphologists, geologists, geographers, archaeologists, anthropologists, ecologists, environmentalists, historians and others in the academic world. Practically, planners and managers interested in landscape/environmental conditions will find interest in these pages, and more generally the increasingly large body of opinion in the general public, with concerns about Planet Earth, will find much to inform their opinions.

Issues In Agroecology – Present Status and Future Prospectus not only reviews aspects of ecology, but the ecology of sustainable food production systems, and related societal and cultural values. To provide effective communication regarding status and advances in this field, this series connects with many disciplines such as sociology, anthropology, environmental sciences, ethics, agriculture, economics, ecology, rural development, sustainability, policy and education, and integrations of these general themes so as to provide integrated points of view that will help lead to a more sustainable construction of values than conventional economics alone. Such designs are inherently complex and dynamic, and go beyond the individual farm to include landscapes, communities, and biogeographic regions by emphasizing their unique agricultural and ecological values, and their biological, societal, and cultural components and processes.

In recent years, tropical forests have received more attention and have been the subject of greater environmental concern than any other kind of vegetation. There is an increasing public awareness of the importance of these forests, not only as a diminishing source of countless products used by mankind, nor for their effects on soil stabilization and climate, but as unrivalled sources of what today we call biodiversity. Threats to the continued existence of the forests represent threats to tens of thousands of species of organisms, both plants and animals. It is all the more surprising, therefore, that there have been no major scientific accounts published in recent years since the classic handbook by Paul W. Richards, The Tropical Rain Forest in 1952. Some excellent popular accounts of tropical rain forests have been published including Paul Richard's The Life of the Jungle, and Catherine Caulfield's In the Rainforest and Jungles, edited by Edward Ayensu. There have been numerous, often conflicting, assessments of the rate of conversion of tropical forests to other uses and explanations of the underlying causes, and in 1978 UNESCO/UNEPI FAO published a massive report, The Tropical Rain Forest, which, although full of useful information, is highly selective and does not fully survey the enormous diversity of the forests.
