Este libro presenta lineamientos para el diseño de sistemas de abastecimiento rurales que apliquen el concepto de usos múltiples del agua. Además de lineamientos técnicos, incluye lineamientos para la administración, operación y mantenimiento de tales sistemas. Su estructura se basa en los principios que deben cumplir los sistemas de uso múltiple, buscando un servicio de agua sostenible, que satisfaga las distintas necesidades de la familia rural.
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
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.
Los usos múltiples del agua son un concepto asociado al acceso al agua por parte de las familias campesinas de las zonas rurales tanto para sus actividades humanas como productivas de subsistencia desde sistemas de abastecimiento domésticos. Esta tendencia implica que los sistemas incluyan en sus dotaciones de agua la cantidad suficiente para que la gente realice sus actividades productivas de subsistencia considerando el uso de diversos tipos de fuentes de agua y la conservación del agua dentro del ciclo antrópico la mayor cantidad de tiempo y usos posibles. En Colombia, la normatividad separa los sectores doméstico y agropecuario, por lo que las actividades productivas de subsistencia no son cobijadas por ningún sector, dejándolas en la ilegalidad de tomar agua de sistemas considerados domésticos o sin el beneficio de un distrito de riego, lo que les implica a las familias campesinas una lucha constante para conseguir su sustento. En aras de avanzar hacia la disminución de la inequidad, lograr una mejor calidad de vida de los habitantes y reivindicar las labores fundamentales de los campesinos rurales colombianos, este libro presenta los resultados de una investigación doctoral orientada a la construcción de lineamientos de políticas públicas para las actividades de subsistencia de la zona rural andina colombiana, es decir, para los usos múltiples del agua. Los lineamientos son un primer paso para abordar el abastecimiento de agua para actividades domésticas y productivas pensados desde la delimitación de las magnitudes de las actividades, la disponibilidad de fuentes de agua y tipos de sistemas de abastecimiento, las necesidades de renovación institucional para adoptarlas y la adaptación del manejo de los sistemas. Los lineamientos de política de uso del agua incluyen una caracterización de las actividades productivas de subsistencia y están estructurados en principios, objetivos y líneas estratégicas, basados en la magnitud de las actividades, la delimitación de las fuentes de agua y los sistemas de abastecimiento, la promoción de la renovación institucional y el fortalecimiento del manejo de los sistemas. Además, el libro presenta una metodología de evaluación de los lineamientos de política pública usando lógica difusa, lo cual permite determinar el estado de los sistemas de abastecimiento antes, durante y después de aplicar los lineamientos. Esta investigación se enmarca en los preceptos conceptuales de la gestión integrada del recurso hídrico, los socioecosistemas, la pobreza, las políticas públicas y la ecología política, fundamentalmente.
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.
Focusing on how to provide clean water for all - one of the key Millennium Development Goals, this book integrates technical and social perspectives. A broad, international range of case studies are provided, from developed, middle income and developing countries, in Europe, Asia, Africa, and the Americas.
