Mexico is currently facing severe problems with water availability, wastage and contamination. The most contaminated and over-exploited water resources are concentrated in the most populated areas of the country, where water is scarcer and its quality makes it unsuitable for a variety of uses, including human consumption. At the same time it is indisputable that water quality is a determining factor in public health and ecosystems. The significant growth in population and industry results in a high demand for water, along with contaminating discharges, few of which are treated – and the impact upon the ecosystems is evident. This book addresses all these topics in a single volume, taking into account the challenges presented by the economic, institutional and environmental considerations in Mexico’s water policy framework.

This report is intended for development practitioners This report is intended for development practitioners, extensionists and leaders or pioneers in farming communities, to inform them about the experiences and initiatives of farming communities in conservation agriculture in Santa Catarina State, Brazil, there have been widespread improvements in soil management. This has led to lower costs and improved returns combined with better conservation and soil resources. The main elements of success were minimum tillage, soil cover management and direct seeding practices, together with an effective and creative extension service. While these developments probably cannot be duplicated as such elsewhere, the methods and strategies may well inspire others to adapt and modify them for application in their own environments elsewhere, the methods and strategies may well inspire others to adapt and modify them for application in their own environments.

Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation. This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.
