Manual para el desarrollo de ferrocarriles urbanos


Book Description

A nivel global, ciudades buscan desarrollar soluciones de transporte asequibles, ecológicas y socialmente responsables que puedan satisfacer las necesidades de conectividad de las crecientes poblaciones metropolitanas y respaldar el futuro desarrollo económico y urbano. Cuando los sistemas ferroviarios urbanos se planifican e implementan adecuadamente como parte de una red de transporte público más amplia, éstis pueden brindar vías rápidas de movilidad y acceso vital a los centros urbanos desde la periferias. Los servicios ferroviarios urbanos de alto rendimiento, cuando se abordan cuidadosamente en el contexto de un proyecto de desarrollo, pueden ayudar a mejorar la calidad de vida de los ciudadanos brindándoles acceso a oportunidades laborales y servicios esenciales, tanto del entorno urbano inmediato como de comunidades vecinas. Este manual sintetiza y difunde conocimientos sobre planificación, implementación y operación de los proyectos ferroviarios urbanos para: i) destacar la necesidad de realizar estudios tempranos y planificar los proyectos, ii) contribuir a que los proyectos sean más sostenibles (desde el punto de vista económico, social y ambiental); iii) mejorar los beneficios socioeconómicos de los usuarios y el acceso de estos a distintas oportunidades; iv) maximizar el valor de la participación privada, cuando corresponda, y v) fortalecer la capacidad de las instituciones encargadas de la gestión e implementación de los proyectos. Se ofrece experiencia para lidiar con los desafíos técnicos, institucionales y financieros a los que se enfrentan los tomadores de decisiones de proyectos ferroviarios urbanos. Se reúnen los conocimientos especializados del personal del Banco Mundial y el aporte de numerosos especialistas para sintetizar buenas prácticas y recomendaciones basadas en experiencia global que no responden a intereses comerciales, financieros ni políticos, entre otros. El material presentado tiene como objetivo servir de guía imparcial para maximizar el impacto y afrontar los desafíos que conllevan los sistemas ferroviarios urbanos en las ciudades de países desarrollados y en desarrollo. No se brinda un enfoque único, sino que se reconocen las complejidades y los distintos contextos existentes cuando se aborda un proyecto de desarrollo ferroviario urbano; de ese modo, se apoya a las autoridades a prepararse para formular las preguntas adecuadas, analizar las cuestiones clave, llevar a cabo los estudios necesarios, aplicar las herramientas apropiadas y aprender de las buenas prácticas internacionales, todo ello en el oportuno momento del proceso de desarrollo del proyecto.

The North American Mosaic


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.
