Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.
This comprehensive volume presents the topic of water resources of Mexico from a different angle. Besides covering the geohydrology it also offers a brief account of the ancient water resources works, explains from where the water is coming, how the water is being used in homes and in the industry, how the dams are operated in the hurricane season, some aspects of the water-energy-food securities nexus and the expectations for the future in connection with global climate change. The book is of interest to every one connected with the water resources of Mexico, e.g. federal and state employees of agencies related with water management, water supply and wastewater treatment. It is also of value to those in academia and employed at water related professional associations and the general public.
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.
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 book presents case studies that share important experiences regarding Integrated Water Resource Management (IWRM) in various countries. Following an introduction to theoretical concepts, responsibilities, and challenges, the subsequent chapters address, among other topics, an analysis of policies and regulations for water management in Brazil, the drivers that led California to adapt to the IWRM framework, and the international regulations for water markets and water banking in Australia and Chile. The implications of climate change for water resource systems in Mexico are discussed, as well as management strategies from California that could potentially serve as IWRM adaptation schemes in Mexico. Critical cases from Guanacaste (Costa Rica), and from Zayandehrud River Basin and Lake Urmia (Iran) are reviewed in terms of management practices and solutions. The book also provides an overview of the current availability and use of water resources in South Korea, and discusses the management of and international water law instruments for transboundary groundwater in Africa.
From time immemorial, people have been managing rain. The availability of water and water sources determined where people would be able to live. Adequate rainfall decided on the quality of agriculture. Technical advances and finance may have enabled societies to inhabit big cities and expand agriculture into dry areas, but only because of the resource rain provided through the water cycle. Due to population growth, pollution, and climate change, water scarcity will be one of the most critical problems all around the world in the next 15 years. Today, around 10% of the world’s population lacks a proper water supply service. Harvesting rainwater and using it for drinking, domestic, industrial, and agricultural uses will help to supply quality water to urban and rural populations. Divided into four sections, basic concepts, narratives of RWH, programs implemented by diverse sectors of society, and notable cases, the book summarizes experiences from 14 different countries all around the globe, developed and developing countries, urban and rural areas. The subject of this book is related to the promotion of different international rainwater experiences that provides sustainable water services and climate resilience, including technical aspects and socio-cultural and policy affairs. This book was written for all people interested in sustainable rainwater management. Students, people just starting in the subject, and experts will find this book interesting as it creates an overview of rainwater harvesting practice and technology all around the world. We encourage all readers to read these stories and arguments at your leisure. Some many ideas and techniques can be picked up and applicable for serving the last 10% that is waiting for water security and proper water service.
Leonardo da Vinci, the eminent Renaissance scholar and philosopher said, "water is the driver of nature". Many may have considered it to be an overstatement in the past, but at the beginning of the third millennium, no sane individual would disagree with Leonardo's view. Water is becoming an increasingly scarce resource for most of the world's citizens. The current trends indicate that the overall situation is likely to deteriorate further, at least for the next two decades, unless the water profession eschews its existing "business as usual" practices, which can only allow incremental changes to occur. Somewhat surprisingly, the water profession as a whole neither realised nor appreciated the gravity of the global water situation as late as 1990, even though a few serious scholars have been pointing out the increasing criticality of the situation from around 1982. For example, the seriousness of the crisis was not a major issue, either at the International Conference on W ater and the Environment, which was organised by the UN system in Dublin and also at the UN Conference on Environment and Development at Rio de Janeiro. Held in 1992, both are considered to be important events for the water sector of the past decade. It is now being increasingly recognised that the Dublin Conference was poorly planned and organised, and thus not surprisingly it produced very little, if any, worthwhile and lasting results.
In Watering the Revolution Mikael D. Wolfe transforms our understanding of Mexican agrarian reform through an environmental and technological history of water management in the emblematic Laguna region. Drawing on extensive archival research in Mexico and the United States, Wolfe shows how during the long Mexican Revolution (1910-1940) engineers’ distribution of water paradoxically undermined land distribution. In so doing, he highlights the intrinsic tension engineers faced between the urgent need for water conservation and the imperative for development during the contentious modernization of the Laguna's existing flood irrigation method into one regulated by high dams, concrete-lined canals, and motorized groundwater pumps. This tension generally resolved in favor of development, which unintentionally diminished and contaminated the water supply while deepening existing rural social inequalities by dividing people into water haves and have-nots, regardless of their access to land. By uncovering the varied motivations behind the Mexican government’s decision to use invasive and damaging technologies despite knowing they were ecologically unsustainable, Wolfe tells a cautionary tale of the long-term consequences of short-sighted development policies.
This book addresses water management issues in the State of New Mexico. It focuses on our current understanding of the natural world, capabilities in numerical modeling, existing and evolving regulatory frameworks, and specific issues such as water quality, endangered species and the evolution of new water management institutions. Similar to its neighboring states, New Mexico regularly experiences cycles of drought. It is also experiencing rapid economic growth while at the same time is experiencing a fundamental climate shift. These factors place severe demands on its scarce water resources. In addition to historical uses by the native inhabitants of the region and the agricultural sector, new competitive uses have emerged which will require reallocation. This effort is complicated by unadjudicated water rights, the need to balance the ever-increasing needs of growing urban and rural populations, and the requirements of the ecosystem and traditional users. It is clear that New Mexico, as with other semi-arid states and regions, must find efficient ways to reallocate water among various beneficial uses. This book discusses how a proper coordination of scientific understanding, modeling advancements, and new and emerging institutional structures can help in achieving improved strategies for water policy and management. To do so, it calls upon the expertise of academics from multiple disciplines, as well as officials from federal and state agencies, to describe in understandable terms the issues currently being faced and how they can be addressed via an iterative strategy of adaptive management.
