Book Description
This book addresses the technical, health, regulatory, and social aspects of ground water withdrawals, water use, and water quality in the metropolitan area of Mexico City, and makes recommendations to improve the balance of water supply, water demand, and water conservation. The study came about through a nongovernmental partnership between the U.S. National Academy of Sciences' National Research Council and the Mexican Academies of Science and Engineering. The book will contain a Spanish-language translation of the complete English text.

Book Description
Descended from a long and ancient lineage, tapirs are important tropical forest seed dispersers. However, today, all species of tapirs are threatened to various degrees by habitat destruction and hunting. This action plan was written with wildlife biologists, ecologists, administrators, educators and local conservation officials in mind and is aimed at those countries with tapir populations. It provides a brief natural history of each species and its objective is to aid in their conservation by catalyzing conservation action. In addition, it is hoped that the contents of the plan will stimulate further research into this fascinating group of animals.

Book Description
Issues In Agroecology – Present Status and Future Prospectus not only reviews aspects of ecology, but the ecology of sustainable food production systems, and related societal and cultural values. To provide effective communication regarding status and advances in this field, this series connects with many disciplines such as sociology, anthropology, environmental sciences, ethics, agriculture, economics, ecology, rural development, sustainability, policy and education, and integrations of these general themes so as to provide integrated points of view that will help lead to a more sustainable construction of values than conventional economics alone. Such designs are inherently complex and dynamic, and go beyond the individual farm to include landscapes, communities, and biogeographic regions by emphasizing their unique agricultural and ecological values, and their biological, societal, and cultural components and processes.

Book Description
This book provides a systematic and comprehensive guide to the current state of knowledge on tourism and water. It is the first book to thoroughly examine the interrelationships of tourism and water use based on global, regional and business perspectives. Its assessment of tourism's global impact along with its overviews of sectoral and management approaches will provide a benchmark by which the water sustainability of tourism will be measured for years to come. In making a clear case for greater awareness and enhanced water management in the tourism sector, it is hoped that the book will contribute to the wise and sustainable use of this critical resource. The book is interdisciplinary in coverage and international in scope. It is designed as essential reading for not only students of tourism but also practitioners.

Book Description
In 2020, a Special Issue titled "Sustainable Rural Development: Strategies, Good Practices and Opportunities" was launched, in which 16 papers were published. The aim of this monograph was to study a problem that is occurring on a global scale and, above all, in the most developed countries, which is the population emigration from rural areas to urban areas due to the labour and service opportunities offered by the latter. This is causing a demographic deterioration of rural areas, and those that remain show high rates of ageing, masculinisation, or low demographic growth. In addition, and interrelated with this demographic deterioration, there is economic and environmental degradation. Rural areas are territories with increasingly lower purchasing power, job opportunities, and services for the population, which are classified as "spaces in crisis". The papers in this Special Issue evidence the many public and private strategies that are being pursued to achieve sustainable rural development in declining areas. The diversity of approaches offer a vision of the practical application and the obstacles or difficulties that many of them are having to achieve their objectives. All of these strategies are intended to achieve economic dynamism that is respectful of the environment and from there to be able to reduce the regressive demographic processes in rural areas. These are different approaches that allow us to contribute, from scientific, holistic, and multidisciplinary knowledge, and they can help decision making in public policy and planning strategies.

Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
