Thirsty Cities


Book Description

Many cities in Latin America and the Caribbean are experiencing a water crisis as sources become exhausted or degraded. Urbanization, deteriorating infrastructures with a lack of funds for repairs, and inadequate polices are conspiring to cause water shortages. People are becoming concentrated in megacities, such as Mexico City with a population of almost 23 million, that have outgrown their water-supply systems. Urban areas are increasingly incapable of supplying water and sewer systems for their populations. By the year 2020, more than 500 million inhabitants of Latin America (two-thirds of.




Groundwater and Society


Book Description

This book takes stock of the development and abuse of groundwater over the past century and measures present approaches to groundwater management against the reality of declining water tables and polluted aquifers. It discusses the impact these have had on people, their livelihoods, communities and environment. The prospects for sustainable development are then examined.







Sustaining the World's Wetlands


Book Description

Wetlands throughout the world, including those described in this book are among the most sensitive and vulnerable ecosystems. They are critical habitats to the world’s migratory birds and a broad range of endangered mammal, reptile, amphibian, and plant species. They provide a broad range of flood storage, pollution control, water supply, ecotourism functions to indigenous peoples and country populations as a whole. They are also at the center of severe land and water use conflicts. These are conflicts between counties where wetland resources or the water supplies required for such resources involve more than one country. These are conflicts in use such as conflicts between habitat protection and charcoal production in mangroves. These are conflicts between groups of peoples such as indigenous peoples and hydropower advocates. Many wetlands have already been destroyed by water extractions, dams, levees, channelization, and fills. Others have been degraded by water pollution, overfishing and overhunting, timber harvest, and a host of other activities. This book describes these conflicts and international policies and institutions developed to protect and manage wetland resources. Most of the broader literature and other books on wetlands focuses on wildlife. Wildlife is described in the case studies, which follow. But, Richard Smardon provides us with more. He traces the history of conflicts and the development of policies and insti- tions to protect and manage wetland resources.

The Roman Villa in the Mediterranean Basin


Book Description

This volume offers a comprehensive survey of Roman villas in Italy and the Mediterranean provinces of the Roman Empire, from their origins to the collapse of the Empire. The architecture of villas could be humble or grand, and sometimes luxurious. Villas were most often farms where wine, olive oil, cereals, and manufactured goods, among other products, were produced. They were also venues for hospitality, conversation, and thinking on pagan, and ultimately Christian, themes. Villas spread as the Empire grew. Like towns and cities, they became the means of power and assimilation, just as infrastructure, such as aqueducts and bridges, was transforming the Mediterranean into a Roman sea. The distinctive Roman/Italian villa type was transferred to the provinces, resulting in Mediterranean-wide culture of rural dwelling and work that further unified the Empire.




The Handbook of Groundwater Engineering


Book Description

Due to the increasing demand for adequate water supply caused by the augmenting global population, groundwater production has acquired a new importance. In many areas, surface waters are not available in sufficient quantity or quality. Thus, an increasing demand for groundwater has resulted. However, the residence of time of groundwater can be of the order of thousands of years while surface waters is of the order of days. Therefore, substantially more attention is warranted for transport processes and pollution remediation in groundwater than for surface waters. Similarly, pollution remediation problems in groundwater are generally complex. This excellent, timely resource covers the field of groundwater from an engineering perspective, comprehensively addressing the range of subjects related to subsurface hydrology. It provides a practical treatment of the flow of groundwater, the transport of substances, the construction of wells and well fields, the production of groundwater, and site characterization and remediation of groundwater pollution. No other reference specializes in groundwater engineering to such a broad range of subjects. Its use extends to: The engineer designing a well or well field The engineer designing or operating a landfill facility for municipal or hazardous wastes The hydrogeologist investigating a contaminant plume The engineer examining the remediation of a groundwater pollution problem The engineer or lawyer studying the laws and regulations related to groundwater quality The scientist analyzing the mechanics of solute transport The geohydrologist assessing the regional modeling of aquifers The geophysicist determining the characterization of an aquifer The cartographer mapping aquifer characteristics The practitioner planning a monitoring network
