Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-dat...

The Chainsaw Operator's Manual is an essential safety tool for chainsaw operators. It is the ultimate guide to basic chainsaw operating techniques covering safety, maintenance and cross-cutting, but not tree felling. Detailed diagrams illustrate horizontal, vertical and boring cuts, as well as trimming and cross-cutting techniques.Safety considerations are discussed, including workplace safety, occupational hazards, kick-back and identifying dangerous trees. An explanation...

Forest Management and Planning provides a focused understanding of contemporary forest management issues through real life examples to engage students. The methodology for the development of quantitatively-derived forest management plans – from gathering information to the implementation of plans at the forest level – are clearly explained. Emphasis is placed on the development of traditional commodity production forest plans using linear programming, the development of alternative forest ...

Ivermectin and abamectin, members of the avermectin family of compounds, were introduced to the market in the 1980's as a veterinary antiparasitic drug and agricultural pesticide, respectively. Their acceptance and commercial success have been remarkable; both are highly effective and in worldwide use. The efficacy of ivermectin in river blindness has expanded the interest in its use in human medicine. In response to the intense scientific and industrial i...

Improving the dynamic relationship between nature and human well-being is a pressing issue of our time. Landscapes embody this tight interconnectedness and serve as unique sustainability learning hubs, showcased by the global rise of place-based and holistic landscape stewardship initiatives. Incorporating these exciting developments, this book explores the principles of landscape stewardship and their function in fields such as agriculture, ecological restoration and urban green infrastru...

This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environmental management. Each volume will be a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement human's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between human...

Jointly published with INRA, Paris.Pesticide resistance is becoming more frequent and widespread with more than 500 insect species known to have become resistant to synthetic insecticides. On the other hand, consumers increasingly demand agricultural products without any pesticide residues. This book, for the first time, shows the alternative: solely physical methods for plant protection by means of thermal, electromagnetic, mechanical and vacuum processes. A glossary rounds up thi...

This book was written to help the forest industry assess wood quality by using non-destructive samples taken from specific points within a tree. It is the first compilation of research data on sampling of eucalypts, describing new methods and tools for rapid and cost-effective analysis. The book provides information needed to design a sampling program, obtain and process wood samples, and shows how to relate the data to an average tree value.

Roots represent half of the plant body – and arguably the more interesting half. Despite its obvious importance for the whole plant, until recently our knowledge of the root apparatus was very limited, mostly due to the inadequacy of the techniques available. Recent advances in the visualization and measurement of roots have resulted in significant progress in our understanding of root architecture, growth and behaviour. In this book international experts highlight the most advanced techni...

This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume1 mainly focuses on 126 species of grass weeds and 34 species of sedge weeds.With the deve...

Aimed at taking the mystery out of soil science, Soils: Principles, Properties and Management is a text for undergraduate/graduate students who study soil as a natural resource. Written in a reader-friendly style, with a host of examples, figures and tables, the book leads the reader from the basics of soil science through to complex situations, covering such topics as:the origin, development and classification of soilphysical, chemical and biological prope...

Forest ecosystems are characterized by a steady change in their structure of function. Natural developments are more and more radically disturbed by human impact. Air pollution leads to soil acidification, change in nutrient budget and to a decreasing vitality of the trees. Forest management can prevent natural succession and often leads to less stable forests. In this book, selected results of 10 years of interdisciplinary ecosystem research are presented. Not only growth and physiologica...
