Book Description
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.

Book Description
The large-scale application of new silvicultural systems has become a political reality in many parts of the world. This involves a gradual transformation of traditional silvicultural practice towards Continuous Cover Forestry, also known as near-natural forest management, favouring mixed uneven-aged stands, site-adapted tree species and selective harvesting. Selective harvesting systems have a long tradition. Specific CCF-related resource assessment, forecasting and sustainable harvest control techniques have been developed, but details about their use are not widely known. The objective of this volume is to present state-of-the-art research results and techniques relating to CCF management with an emphasis on systems engineering and modelling. Using a very simple classification based on the development of timber volume over age or time we may distinguish two types of sustainable forest management systems. Rotation forest management (RFM) systems, characterized by standard silvicultural treatments and repetitive cycles of clearfelling followed by planting; and continuous cover forestry (CCF) systems which are characterized by selective harvesting and natural regeneration, resulting in uneven-aged structures and frequently also in multi-species forests. The distinction is usually the result of decisions relating to the cost of timber harvesting, simplicity of management, or various intangible benefits. The oldest and most perfect examples of CCF systems are the so called plenter selection forests found in France, Switzerland, Slowenia and Germany. Today, CCF systems are encountered in various regions of Europe, North America and in some tropical and sub-tropical forests of South Africa, Asia and South America.

Book Description
It was in late 2002 that the idea of preparing a collection of multi-authored chapters on different aspects of ag- st forestry as a compendium for the 1 World Congress of Agroforestry, June 2004, was tossed around. With the approval of the idea by the Congress Organizing Committee, serious efforts to make it a reality got under way in early 2003. The rigorously peer-reviewed and edited manuscripts were submitted to the publisher in December 2003. Considering the many differentindividualsinvolved in the task as authors and manuscriptreviewers, we feel quite pleased that the task could be accomplished within this timeframe. We are pleased also about the contents on several counts. First of all, the tropical-temperate mix of topics is a rare feature of a publication of this nature. In spite of the scienti?c commonalities between tropical and temperate practices of agroforestry, the differences between them are so enormous that it is often impossible to mesh them together in one publication. Secondly, several of the chapters are on topics that have not been discussed or described much in agroforestryliterature. A third feature is that some of the authors, though well known in their own disciplinary areas, are somewhat new to agroforestry; the perceptions and outlooks of these scholars who are relatively unin?uenced by the past happenings in agroforestry gives a whole new dimension to agroforestry and broadensthescopeofthesubject. Finally, ratherthanjustreviewingandsummarizingpastwork,mostchapterstake the extra effort in attempting to outline the next steps.

Book Description
Die moderne Geschichte Ägyptens und des Sudan hat mehrfach radikal in die nubische Lebenswelt eingegriffen und tut dies bis auf den heutigen Tag: Nach den großen Staudammbauten des 20. Jahrhunderts sind neue Damm-, Bau- und Schürfprojekte auch im 21. Jahrhundert der Anlass, unter enormem Zeitdruck großflächig nubisches Terrain zu erforschen. Hierdurch bedingt wurde auf allen Gebieten der Kulturgeschichte ein gewaltiger Wissenszuwachs erreicht. Ergänzt wird dies durch Entdeckungen in ägyptischen Fundplätzen, angrenzenden Wüstengebieten und benachbarten Großräumen. Die 42 Beiträge dieses Handbuches zielen auf die diachrone, regionale und großräumliche Perspektive. Beginnend mit den Befunden der Altsteinzeit wird der Weg hin zu dem Nebeneinander pastoraler Gesellschaften und größerer Kulturäume in der Flussaue dargestellt. Über die bronzezeitlichen Kulturen wird der Bogen zu den Königreichen von Napata und Meroe bis hin zu den christlichen Königreichen und der islamischen Frühneuzeit gespannt. Dieser Sammelband beabsichtigt, den interessierten Kulturwissenschaftler auf den jüngsten Stand der Forschung zu bringen und die wechselvolle Geschichte dieses Bindeglieds zwischen dem Mittelmeerraum und Afrika zu vermitteln.

Book Description
The cultures of Nubia built the earliest cities, states, and empires of inner Africa, but they remain relatively poorly known outside their modern descendants and the community of archaeologists, historians, and art historians researching them. The earliest archaeological work in Nubia was motivated by the region's role as neighbor, trade partner, and enemy of ancient Egypt. Increasingly, however, ancient Nile-based Nubian cultures are recognized in their own right as the earliest complex societies in inner Africa. As agro-pastoral cultures, Nubian settlement, economy, political organization, and religious ideologies were often organized differently from those of the urban, bureaucratic, and predominantly agricultural states of Egypt and the ancient Near East. Nubian societies are thus of great interest in comparative study, and are also recognized for their broader impact on the histories of the eastern Mediterranean and the Near East. The Oxford Handbook of Ancient Nubia brings together chapters by an international group of scholars on a wide variety of topics that relate to the history and archaeology of the region. After important introductory chapters on the history of research in Nubia and on its climate and physical environment, the largest part of the volume focuses on the sequence of cultures that lead almost to the present day. Several cross-cutting themes are woven through these chapters, including essays on desert cultures and on Nubians in Egypt. Eleven final chapters synthesize subjects across all historical phases, including gender and the body, economy and trade, landscape archaeology, iron working, and stone quarrying.
