Book Description
Spain is facing an increasingly difficult situation in terms of water stress. This is an issue that is due mostly to poor management practices in all sectors. Large amounts of water have been used for agricultural purposes at very low prices for too long; there is an uncontrolled use of most aquifers in rural areas which result from ineffective control by the public administration; per capita consumption continues increasing as well as water used for industrial and energy generation, the construction and tourism sectors and for recreation activities. In fact, they have all exerted additional pressure on available water resources. In order to face the above challenges, water policy has made a gradual shift towards more rational and sustainable management of water resources. This has also been influenced by the European Water Framework Directive about which, as the book discusses, there are both myths and misunderstandings. This book analyses the very complex position of all sectors in the country, the alternatives available and the challenges ahead. In so doing, it makes an important contribution to the literature on water resources management. This book was published as a special issue of the International Journal of Water Resources Development.

Book Description
"El agua, como fuente de vida para el desarrollo de las funciones sociales, económicas y ambientales, condiciona sin duda el progreso de la ciudad. La alta concentración urbana, el cambio de uso del suelo y la progresiva contaminación someten hoy los recursos hídricos a una fuerte presión, lo que ocasiona insoportables y permanentes escenarios de crisis. La tendencia actual urbana en el uso del agua es sencillamente insostenible, dado el actual modelo de desarrollo urbano, que no contempla las consecuencias del uso indiscriminado de los recursos naturales de su entorno. No es razonable financiar el costo económico, social y ambiental para el abastecimiento de grandes poblaciones con escurrimientos superficiales transportados de otras vertientes, con sobre-explotación y agotamiento de acuíferos o deterioro sin freno de la calidad de las aguas. Para mitigar esta grave situación y hacer posible un aprovechamiento sostenible del agua, es necesario poseer un amplio conocimiento de las causas que originan su escasez y deterioro, así como de los instrumentos de gestión y de las herramientas más adecuadas para corregir el problema. Hay en este documento información valiosa para comprender y ahondar sobre el tratamiento idóneo de los recursos hídricos para asegurar su permanencia en el mundo urbano y rural."--Page 4 of cover.

Book Description
For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.
