This book contains a selection of papers presented at the first International Symposium on Windbreak Technology, summarising the available worldwide literature on windbreaks and the response, both positive and negative, to wind protection. State-of-the-art information is presented on general design criteria, and principles of planting and establishment for a wide range of conditions and objectives. It provides descriptive information of tree and shrub species for arid, semi-arid, temperate and tropical areas, and their use in windbreaks.

This volume is a collection of 31 multi-authored, rigorously peer-reviewed chapters on different aspects of agroforestry, produced as a compendium on the occasion of the 1st World Congress of Agroforestry, June 2004. Its contenst include a tropical-temperate mix of topics, which is a rare feature of a publication of this nature. Several of the chapters are on topics that have not been discussed or described much in agroforestry literature. 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 uninfluenced by the past happenings in agroforestry gives a whole new dimension to agroforestry and broadens the scope of the subject. Finally, rather than just reviewing and summarizing past work, most chapters take the extra effort in attempting to outline the next steps. Agroforestry stands to gain enormously from the infusion of these new and different ideas and bold initiatives, thus making the title "New Vistas" quite justifiable.

The Great Depression of the 1930s set the stage for "the greatest afforestation program the world has known" when the Forest Service was given the task of planting shelterbelts from Texas to Canada in a zone a hundred miles wide. The venture, known as the Prairie States Forestry Project or the Shelterbelt Project, resulted in the planting of millions of trees between 1834 and 1942. Today, the millions of trees planted in the Depression stand as a monument to President Franklin D. Roosevelt, who originated the idea of the project, and to friends of environmental concern everywhere. Not all the trees are living, and many of the belts have been removed in the interest of technological advances in Plains' agriculture or the farmer's decision to increase his planting acreage. Conservationists and spokesmen in government have become alarmed by the destruction of the belts. The time has come to re-evaluate the importance of trees to the environment of the prairies and plains of mid-America, for recent droughts again created a need to plant trees to combat erosion and to make the region more hospitable to the people who live there and who provide the world with its bread.

Windbreaks is a comprehensive guide to the theory and practice of windbreak establishment. Based on many years' research, this book presents the latest scientific information on the subject in an accessible and practical manner.

This college-level textbook summarizes the state of current knowledge in the rapidly expanding field of agroforestry. The book, organized into 25 chapters in six sections, reviews the developments in agroforestry during the past 15 years and describes the accomplishments in the application of biophysical (plant and soil related) and socioeconomic sciences to agroforestry. Although the major focus of the book is on the tropics, where the practice and potential of agroforestry are particularly promising, the developments in temperate zone agroforestry are also discussed. This text is recommended for students, teachers, and researchers in agroforestry, farming systems, and tropical land use.
