Download or read book The Organization of Agricultural Production at a Classic Maya Center written by Rodrigo Liendo Stuardo and published by Center for Comparative Arch. This book was released on 2002 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed analysis of the economic foundations of the prehispanic Maya city of Palenque. Full information on extensive ridged field systems in Palenque's immediate hinterland and on the rural settlement associated with them. The study concludes that, initially, the construction and use of these ridged fields systems was strongly controlled and managed by elites residing in the city itself. Later in the sequence there is a substantial decrease in central administrative control. Detailed data are available electronically. Complete text in English and Spanish.

This book was released on 2008-04-16 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: El cambio global afectará de forma importante a la biodiversidad y a los servicios ecosistémicos. El empleo de atributos funcionales de los ecosistemas a escala regional en la evaluación de las consecuencias de estos cambios se muestra ventajoso a la hora de conectar los estudios locales y globales y de cara a establecer programas de seguimiento. Sin embargo, no son muchos los trabajos a escala regional que analizan los efectos del cambio global sobre el funcionamiento de los ecosistemas de la Península Ibérica o que proporcionen una situación de referencia frente a la que comparar el efecto del uso de la tierra y de los cambios climáticos y atmosféricos sobre los ecosistemas. En esta Tesis se documentaron los patrones espaciotemporales de la fracción de radiación fotosintéticamente activa (fPAR) interceptada por parte de la vegetación actual de la Península Ibérica, así como las tendencias observadas en la misma para los ecosistemas protegidos bajo la Red Española de Parques Nacionales. También, se exploraron los controles climáticos y de usos del suelo que subyacen detrás de los patrones encontrados. Para ello, se empleó como medida integradora del funcionamiento ecosistémico un estimador del fPAR y, por tanto, de la productividad primaria neta: el Índice Verde Normalizado (NDVI) obtenido a partir de imágenes NOAA/AVHRR entre 1982 y 1999. Se utilizaron los siguientes atributos funcionales de las curvas estacionales de este índice: la integral anual, la variabilidad intraanual o rango relativo, los valores máximo y mínimo de NDVI, la época en la que se alcanzan estos valores, y las variabilidades interanuales de todos ellos. Se identificaron Tipos Funcionales de Ecosistemas que recogieron de forma sintética la heterogeneidad espacial del fPAR en la Península y cuyos patrones sugieren que el uso de la tierra modifica a escala regional los ciclos del carbono. La precipitación, la temperatura, la vegetación potencial y el tipo de uso por el cual se la reemplaza, controlaron la magnitud y el sentido de las diferencias en la dinámica del NDVI. La caracterización de atributos funcionales en áreas naturales, seminaturales y protegidas de España reveló los diferentes controles que determinan la dinámica del NDVI a lo largo de los gradientes ambientales entre la Región Mediterránea y la Eurosiberiana. El análisis sobre parques nacionales mostró algunos huecos en la Red y permitió diferenciar aquellos parques que representan tipos de funcionamiento ecosistémico singulares en el contexto ibérico, de aquellos otros que constituyen paisajes representativos del funcionamiento de gran parte de la vegetación ibérica. Además, nuestros resultados pusieron de manifiesto cómo los parques nacionales españoles, áreas con altos niveles de protección, tendieron a aumentar la productividad y a disminuir las diferencias entre las estaciones de crecimiento y de reposo en el corto plazo. En conjunto, esta Tesis ofrece una caracterización de referencia frente a la que evaluar los efectos del cambio global sobre el funcionamiento de los ecosistemas ibéricos y con la que incorporar aspectos funcionales de los ecosistemas a las políticas de conservación de la naturaleza y de mantenimiento de los servicios ecosistémicos, en concreto, los relacionados con el secuestro de carbono.

Download or read book Pay written by Mark Smith and published by IUCN. This book was released on 2006 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide aims to provide practical tools to non specialists-essentially water resources planners, river basin managers, non-governmental organizations and private sector operators. It links the most recent practice on payments for hydrological services to current discourse on integrated water resources management and looks into the different aspects to consider when exploring the potential feasibility of establishing reward or payments for ecosystem services related to water security. Pay demystifies concepts and jargon, and through a series of tools, case studies and stories from around the world, describes pitfalls to avoid and provides hints to fill gaps in knowledge. It is based on a demand-driven approach, linking text, tools and illustrations to key questions emerging from current and potential practitioners.
