Book Description
"En el presente estudio, se muestran cuáles son las tecnologías que mayor uso están teniendo en la actualidad para renovar y rehabilitar tuberías para distribución de agua potable identificando sus ventajas y desventajas frente al método tradicional de zanja abierta, en donde se hace un mayor énfasis en los aspectos ambientales, ecológicos, económicos y en costos sociales. Sin embargo, no necesariamente estas tecnologías con mayor uso en la actualidad serán las que sean utilizadas a futuro, por lo que en este estudio se reflejan cuáles son las tecnologías más promisorias para renovar y rehabilitar tuberías para distribución de agua potable tanto a corto plazo como a largo plazo." -- Tomado del Formato de Documento de Grado.

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
Vacant urban land--the product of land market activity, the actions of private agents, and the policies of public agents--is an important challenge for policy makers. Vacant lots on the urban fringe and in central and interstitial areas have affected growth patterns in Latin America. Contributors to this book analyze the problems and opportunities related to vacant urban land in five cities: Buenos Aires, Argentina; Rio de Janeiro, Brazil; Quito, Ecuador; Lima, Perú; and San Salvador, El Salvador.

Book Description
This book provides a systematic and comprehensive guide to the current state of knowledge on tourism and water. It is the first book to thoroughly examine the interrelationships of tourism and water use based on global, regional and business perspectives. Its assessment of tourism's global impact along with its overviews of sectoral and management approaches will provide a benchmark by which the water sustainability of tourism will be measured for years to come. In making a clear case for greater awareness and enhanced water management in the tourism sector, it is hoped that the book will contribute to the wise and sustainable use of this critical resource. The book is interdisciplinary in coverage and international in scope. It is designed as essential reading for not only students of tourism but also practitioners.

Book Description
This publication deals with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural development interventions, with often long-lasting, negative results. This guide is designed to assist technical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination, and conflicts, where land tenure is currently of critical concern.

Book Description
Based on twenty case studies of universities worldwide, and on a survey administered to leaders in 101 universities, this open access book shows that, amidst the significant challenges caused by the COVID-19 pandemic, universities found ways to engage with schools to support them in sustaining educational opportunity. In doing so, they generated considerable innovation, which reinforced the integration of the research and outreach functions of the university. The evidence suggests that universities are indeed open systems, in interaction with their environment, able to discover changes that can influence them and to change in response to those changes. They are also able, in the success of their efforts to mitigate the educational impact of the pandemic, to create better futures, as the result of the innovations they can generate. This challenges the view of universities as "ivory towers" being isolated from the surrounding environment and detached from local problems. As they reached out to schools, universities not only generated clear and valuable innovations to sustain educational opportunity and to improve it, this process also contributed to transform internal university processes in ways that enhanced their own ability to deliver on the third mission of outreach
