This book was released on 1994 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with arbuscular mycorrhizas, an essential component of soil/plant systems occurring in the majority of plant species in natural agro-ecosystems. It contains the most recent advances in; the field of the development of biomolecular methods adapted to arbuscular mycorrhizal fungi; the promotion of innovative ecological research which considers biodiversity; elucidating the role of arbuscular mycorrhizas in plant development and root morphology; and defining the cellular and molecular basis of plant-fungus exchanges
Download or read book Water and Sustainability in Arid Regions written by Graciela Schneier-Madanes and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: International voices fill the pages of Water and Sustainability in Arid Regions, forming an original scientific exploration of current water research and management issues. In arid regions, agriculture that is ill-adapted to the environment, accelerated urbanization, poverty, and increasing pollution challenge access to and uses of water. Understanding these issues requires incorporating findings from both the physical and social sciences at different temporal and spatial scales. The chapters in this book were written by hydrologists, remote sensing specialists, ecologists, historians, economists, political scientists, architects, archaeologists, and other experts who live in and study arid lands. The authors present updates, overviews, and analyses of water challenges these areas have faced and are striving to address, from salinization in the fabled Taklimakan Desert in China to land degradation in the northern Mediterranean to groundwater over-exploitation in the southwestern United States. The book also examines desertification, remote sensing, qanat systems, architecture, arsenic contamination, and other case studies from Iran, the Maghreb region, Argentina and Chile, and Mexico. From this conceptual mosaic of comparative perspectives and research methods emerges a strong assumption: an interdisciplinary approach that combines physical and social sciences is the first step toward globally and comprehensively addressing water and sustainability."This book is a valuable and welcome contribution to the discussion of water and sustainable development. Through the collection of chapters, the book clearly illustrates the contemporary diversity of approaches to water scarcity and presents pertinent and new research findings that readers generally do not find compiled together. The result is a highly relevant, accessible, and timely resource that is unique in its international and interdisciplinary content. This is a must-read for anyone working on environmental and sustainability issues in arid lands."André Mariotti, University Pierre et Marie Curie, and INSU - CNRS (National Institute for Earth Sciences and Astronomy-National Center for Scientific Research/Centre National de la Recherche Scientifique), France "Anyone who reads this book will find himself or herself contemplating the need to rethink how we approach the issue of water and sustainability in arid lands. Drawing on the expertise of both physical and social scientists, the chapters taken as a whole present global, historic, and current perspectives on water scarcity in a multi-layered way that rarely has been done before."

Download or read book Agroforestry Parklands in Sub Saharan Africa written by Jean-Marc Boffa and published by Food & Agriculture Org.. This book was released on 1999 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document attempts to present the current state of knowledge on agroforestry parkland systems. These systems, which for many local populations are very important for food security, income generation and environmental protection, are found primarily in the semi-arid and sub-humid zones of West Africa. The document first provides a thorough description of their distribution and diversity and discusses different ways of classifying them. It also presents data on current trends in parkland development and assesses determining factors. The document then provides an in-depth analysis of biophysical tree-soil-crop interactions and the factors regulating them, and describes various improved parkland management techniques. It goes on to examine the strength and limitations of institutional arrangements as well as the constraints imposed by Sahelian forest policies on the sustainable management of parklands. The production, use and marketing of parkland products is reviewed with an emphasis on their contribution to food security, local and national income as well as social values. Overall costs and benefits of the practice of parkland agroforestry are evaluated. In conclusion, the document identifies crucial research needs and promising avenues for promoting sustainable management of parkland systems.
