An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.
The Guiana Shield is an ancient geological formation located in the northern part of South America, covering an area of one million square kilometres. Despite its hostile environment, it is home to many unusual and highly specialized plants and animals, which constitute a rich area of biodiversity. Chapters in this book include hydrology, nutrient cycling, forest phenology, insect-plant interactions, forest microclimate, plant distributions, forest dynamics and conservation and management of flora and fauna. It provides a comprehensive and detailed review of the ecology, biology and natural history of the forests of the area.
"This book presents results of a soil inventory carried out in the Mabura-Kurupukari area in Central Guyana. Included are a soil map with description of mapping units, and profile descriptions with soil analytical data." -- T.p. verso.
Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.
New perspectives on transitions in human history This book is about transitional periods of cultural and environmental change as seen through the lenses of archaeology and ethnography. Incorporating data from across six continents and tracing the human experience from the Late Pleistocene to the present, these chapters offer a global comparative perspective on transitional states. Questions of causality are considered, as are hypotheses about the processes of cultural change. Archaeology on the Threshold focuses on major transitions such as the shift from foraging to agriculture, the adoption of new technologies, the emergence of large-scale societies, the transition from egalitarian to inegalitarian leadership, and changes that occur in socioeconomic and ideological systems as a result of climate change and disease. Theoretical approaches range from processual to postprocessual, humanistic, and interpretive. Methodologies include ethnoarchaeology, the use of ethnographic analogy, cross-cultural comparisons and large-scale data approaches, oral history, the historical record, participant observation, and focus group discussions. Challenging archaeologists to query long-held assumptions and theoretical positions, this volume aims to refocus inquiry into change-causing and larger evolutionary processes to problematize notions of revolutionary, irrevocable change. These case studies examine and shed light on assumptions regarding the linearity and oscillations of adaptations, with intriguing implications for archaeological inferences.
