DOWNLOAD EBOOKThe orang-utan is a superb representative of a major sector of the structure of biological diversity in Sumatra and Borneo. Conservation of the living conditions of the orang-utan implies maintaining the integrity of the entire natural ecosystem of indigenous plant and animal species known as the West Malesian rainforest, i.e. the natural tropical evergreen forests of distinctive floral composition which stretch from the isthmus of Kra, in Thailand, across peninsular West Malaysia, south and eastwards, including Sumatra, Borneo and Java. The main question behind this study is: What is the current status of the orang-utan? Or in other words: • what is the current geographical distribution range? • what have been the trends in the size of its range and numbers? • to what extent is this range covered by (a) conservation areas, (b) timher concessions (i.e. modified habitat) and (c) plans for conversion (i.e. obliteration of the habitat)? • what is the current quality of habitat in this range and what is the prospect for conservation or restoration of such habitat? • what is a plausible average density of the ape in such habitat? • what are the prospects for protection of the ape? • what should and can be clone to give the ape a chance of survival? Several actions were undertaken to find answers to these questions, and the major results are: • In Sumatra the orang-utan has a much more extensive range than was hitherto

DOWNLOAD EBOOKAgricultural lands worldwide are deteriorating, becoming acidic and losing essential humus content. This impacts global food quality and nutrition. Causes include extreme natural events and harmful human activities like deforestation. The consequences are stark—shrinking agricultural land, reduced fertility, lower crop yields, and increased costs. Developing nations face food shortages, population decline, and shortened life expectancy. The urgency demands international cooperation, legislation, and technological advancements. Ecological Aspects of Soil and Land Preservation delves into this critical issue, emphasizing the need for collective action and sustainable solutions. Ecological Aspects of Soil and Land Preservation serves as a resource for scholars, students, and professionals committed to addressing the crisis. This book collects, summarizes, and analyzes the latest information on agricultural land and forest degradation. Beyond that, it introduces groundbreaking hypotheses, theories, and solutions, enriching the scientific community's understanding. The objective is clear: to be an informative resource that not only sheds light on the problem but also catalyzes actionable solutions.

DOWNLOAD EBOOKWith descriptions of hundreds of the most important environmental and ecological models, this handbook is a unique and practical reference source. The Handbook of Environmental and Ecological Modeling is ideal for those working in environmental modeling, including regulators and managers who wish to understand the models used to make assessments. Overviews of more than 360 models are easily accessed in this handbook, allowing readers to quickly locate information they need about models available in a given ecosystem. The material in the Handbook of Environmental and Ecological Modeling is logically arranged according to ecosystem. Each of the sixteen chapters of the handbook covers a particular ecosystem, and includes not only the descriptions of the models, but also an overview of the state-of-the-art in modeling for that particular ecosystem. A summary of the spectrum of available models is also provided in each chapter. The extensive table of contents and the easy-to-use index put materials immediately at your fingertips.

Human Activities and the Tropical Rainforest

DOWNLOAD EBOOKArising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself. Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has been to suggest that rainforest, because of its complexity and the complexity of people-rainforest relationships throughout time, deserves study from a broad perspective. This book poses more questions than answers about the rainforest and it is hoped that it will encourage readers to think about the rainforest in a wider way than hitherto. This book is aimed at geographers (physical and human), social anthropologists, archaeologists, pedologists, foresters and tropical botanists and will be of value to graduates of various disciplines setting out to research the rainforest.
