Los desiertos y la desertificación
Author: Jaime Martínez ValderramaPublisher: LOS LIBROS DE LA CATARATA
ISBN: 8490973121
Category : Science
Languages : es
Pages : 104
Book Description
Los desiertos no son una suerte de monstruos con voluntad propia que arrasan territorios fértiles y prósperos. Son ecosistemas complejos y maduros fruto de unas condiciones extremas de aridez. La desertificación, por el contrario, es un proceso que permanece latente, propio de las zonas secas, y que se desencadena por intervenciones humanas inadecuadas, es decir, por una mala planificación cuya solución pasa por la prevención y el desarrollo de herramientas de vigilancia y de alerta temprana. Esta obra trata de aclarar la diferencia entre ambos conceptos, pues los mitos y la confusión han rodeado siempre este proceso de degradación propio de las tierras secas. Conocer sus causas es indispensable para proponer actuaciones efectivas.

Pages : 240
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.

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.
War Against All Puerto Ricans
Author: Nelson A DenisPublisher: Bold Type Books
ISBN: 1568585020
Category : Political Science
Languages : en
Pages : 402
Book Description
The powerful, untold story of the 1950 revolution in Puerto Rico and the long history of U.S. intervention on the island, that the New York Times says "could not be more timely." In 1950, after over fifty years of military occupation and colonial rule, the Nationalist Party of Puerto Rico staged an unsuccessful armed insurrection against the United States. Violence swept through the island: assassins were sent to kill President Harry Truman, gunfights roared in eight towns, police stations and post offices were burned down. In order to suppress this uprising, the US Army deployed thousands of troops and bombarded two towns, marking the first time in history that the US government bombed its own citizens. Nelson A. Denis tells this powerful story through the controversial life of Pedro Albizu Campos, who served as the president of the Nationalist Party. A lawyer, chemical engineer, and the first Puerto Rican to graduate from Harvard Law School, Albizu Campos was imprisoned for twenty-five years and died under mysterious circumstances. By tracing his life and death, Denis shows how the journey of Albizu Campos is part of a larger story of Puerto Rico and US colonialism. Through oral histories, personal interviews, eyewitness accounts, congressional testimony, and recently declassified FBI files, War Against All Puerto Ricans tells the story of a forgotten revolution and its context in Puerto Rico's history, from the US invasion in 1898 to the modern-day struggle for self-determination. Denis provides an unflinching account of the gunfights, prison riots, political intrigue, FBI and CIA covert activity, and mass hysteria that accompanied this tumultuous period in Puerto Rican history.
VOLUNTARY GUIDELINES ON NATIONAL FOREST MONITORING

Pages : 76
Book Description
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.
