Book Description
De acuerdo con los resultados obtenidos apuntamos que es factible diseñar una metodología de evaluación social para los proyectos de apoyo a la producción. En cuanto a las inversiones públicas en el sistema de caminos rurales se observa que los beneficios sociales que rinden superan a sus costos sociales por lo que socialmente son aceptables. En esta forma se verifican las hipótesis planteadas al principio de la investigación. Se considera que la estructura y conducción de la metodología aplicada, expone con claridad el sentido de el análisis, por lo que su extensión para analizar y decidir qué proyecto realizar, cuándo y en qué lugar, con inversiones del sector público, no representan mayor dificultad. La posibilidad de poder expresar en unidades económicas bien precisas la rentabilidad de un proyecto y su repercusión específica sobre determinados objetivos de prioridad e interés para las entidades responsables de la planificación nacional, confiere a este tipo de análisis cuantitativo un grado de confiabilidad que crece en la medida que los parámetros nacionales derivados de un plan de desarrollo tengan mayor coherencia y poder de predicción. El programa carretero es altamente rentable para los tres objetivos evaluados independientemente (excepto a la tasa de 30.0% y Pmo donde B=-0.0) al tener el VAN valores positivos, asimismo en forma agregada el rendimiento es bien satisfactorio para las mismas tasas de actualización. Dentro del rendimiento global el objetivo que mayormente contribuye es el de redistribución regional del ingreso a los tres niveles empleados para la tasa de descuento y el que menor repercusión tiene es el consumo global de acuerdo con el criterio del valor actual neto. El impacto del Pdiv sobre el rendimiento global de la inversión es notoriamente bajo, en realidad se ha utilizado este precio sombra sólo para hacer más completa la metodología de evaluación, sin embargo, tiene gran relevancia para otro tipo de proyectos. De acuerdo al análisis de sensibilidad el objetivo más afectado es el de consumo global que a la tasa de 18% reduce en 15.0% el valor de la REN. El conocimiento de la rentabilidad social de los caminos rurales debe influir positivamente para considerar la conveniencia de elevar las normas de su construcción.

Book Description
Benchmarking has become a key tool in the water industry to promote and achieve performance targets for utilities. The use of this tool for performance improvement through systematic search and adaptation of leading practices, has expanded globally during the past decade. Many ongoing projects worldwide aim to address different needs and objectives, in varying contexts, with outstanding results and impact. Benchmarking Water Services provides valuable information to everyone interested in benchmarking in the water industry. The text is aimed at utilities considering joining a benchmarking project, experienced practitioners in charge of organizing a benchmarking exercise, consultants, regulators and researchers. The document is presented with a clear practice oriented approach and can be used as a how-to-benchmark guide presented from different perspectives (participants, organizers, supervising bodies). Readers will gain practical insight on real life benchmarking practices and will benefit from the experiences gained in some of the leading benchmarking projects of the water industry (including the IWA-WSAA benchmarking efforts, the European Benchmarking Co-operation and the several benchmarking projects carried out in Austria and Central Europe). The manual also presents the new IWA Benchmarking Framework, which aims to harmonize the terms used to describe benchmarking and performance indicators practices in the water industry, guaranteeing a more fluent and efficient communication. This Manual of Best Practice is edited by the IWA Specialist Group on Benchmarking and Performance Assessment, and co-published by AWWA and IWA Publishing. Praise for Benchmarking Water Services: "The continual trend of conceptual to specifics throughout the book provides for an educational experience each time the book is either casually perused or carefully studied." "The authors (Cabrera, Haskins and Fritiz) diligently pursue the focus of improvement." "Benchmarking Water Services is an in depth and practical ‘must have’ guide for any utility currently engaged in or planning to develop a benchmarking process" - Gregory M. Baird (2012) Benchmarking: An International Journal 19:2.

Book Description
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.

Book Description
The book is based on the exchange of professional experiences which featured in an IUCN CEC workshop in August 2002. Practitioners from around the world shared their models of good practice and explored the challenges involved in engaging people in sustainability. The difficulties facing practitioners vary between country and context but some challenges are universal: A lack of clarity in communicating what is meant by sustainable development; An ambition to educate everyone to bring about a global citizenship; Social, organisational or institutional factors constrain change to sustainable development, yet there is an emphasis on formal education, and community educators do not receive the same support; A lack of balance in addressing the integration of environmental, social and economic dimensions leading to an interpretation that ESD is mainly about environment and conservation issues; New learning (rather than teaching) approaches are called for to promote more debate in society. Yet, few are trained or experienced in these new approaches. Practitioners need support to explore new ways of promoting learning. [Foreword, ed].

Book Description
The questionnaire-based Contingent Valuation Method (CVM) asks people what would they be willing to pay for an environmental good or attribute, or willing to accept for its loss. These papers consider the real value of such surveys.
