During the past two centuries, hundreds of millions of people lived around rivers, which necessitated control of these rivers to provide assured water supply for domestic, agricultural and industrial purposes and to reduce flood and drought damages. Thus, the building of dams has gained steady momentum. More recently, after the 1930s, water requirements increased exponentially in countries where there was significant immigration to satisfy the needs of their expanding populations.

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.

The book covers from how to characterize groundwater and evaluate its resources to determining the interactions between surface water and groundwater. This expansive guide reviews both established and innovative aquifer restoration techniques and technologies, including the control and remediation of contaminant sources and groundwater contaminant plumes, resource augmentation, the engineering necessary for resource development, and building comprehensive databases for efficient, cost-effective assessment.

Geostatistical technology has advanced much in the last few years and many of these developments are being incorporated into the practitioner’s repertoire. This second edition describes these techniques for environmental scientists. Topics such as stochastic simulation, sampling, data screening, spatial covariances, the variogram and its modeling, and spatial prediction by kriging are described in rich detail. At each stage the underlying theory is fully explained, and the rationale behind the choices given, allowing the reader to appreciate the assumptions and constraints involved.

En este trabajo se aborda el análisis de la pobreza a partir de las dificultades de su conceptualización y de los distintos métodos para medirla, empleados con el fin de determinar quiénes se encuentran en esa condición, y establece también si en dichos parámetros está contemplada la escasez de agua. De igual manera, se estudia si hay elementos para sostener la existencia del derecho humano al agua y la relación que guarda con las políticas públicas que tienen que ver con los grupos en situación de pobreza y se discute sobre la forma en que las políticas públicas mexicanas contribuyen a combatir la escasez de agua que padecen los mencionados grupos.
