The physics of land drainage. The theory of land drainage. Engineering aspects of land drainage. Drainage invfestigation methods. Land drainage in relation to soils and crops.

Fully renewed and extended, this edition is a valuable source of information for anyone involved in drainage engineering and management. It provides new theories, technologies, knowledge and experiences in combination with traditional land development practices in the humid temperature zone. Aspects covered include: management and maintenance; drainage application and design; and adverse impacts on the environment. Intended as both a handbook and a textbook, this work is of particular value to university students as well as professionals within drainage development, engineering and management.

This text book brings together 26 chapters, 546 fugures, 166 tables, a glossary of 332 definitions. Being the result of ILRI's core business: bringing together the principles and applications of drainage, by giving international courses on drainage

North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.

Man’s control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.
