Se han ido formando políticas ambientales, con especial atención al papel correspondiente a la Unión Europea, en la que se ha llegado a una esencial función pública de protección al medio ambiente, que se sustenta en unos principios generales y unos derechos básicos. La política ambiental europea introdujo aire fresco, mecanismos renovadores, en las anquilosadas posturas sobre el medio ambiente de nuestras regulaciones tradicionales, obligando a actuar a las administraciones públicas españolas en términos más efectivos. El impacto del Derecho derivado europeo se dejó sentir en la regulación de todos los elementos ambientales: aguas, residuos, evaluación ambiental, costas, espacios naturales, delito ecológico… Todo esto nos hace confiar en que hay indicios de cambios profundos en la reacción del Derecho frente a la problemática ambiental.

In recent times what has become known as "the case of Medellín " has generated a growing interest in the international community. These urban transformation that Medellín has experimented have become a focus of attention and reference for experts in many fields, around the world. The book ́Medellin: Environment, Urbanism and Society ́, that now published the Center for Urban and Environmental Studies, Urbam, of EAFIT University is a testimony of the value given by our culture to the accomplishments of the city, to the idea of the public sphere and the growing relationship between the technical sphere and the political sphere, understood in the broad sense as a form of disciplinary knowledge and construction of civil society. This book brings together a knowledge of the city from multiple perspectives; knowledge that is, without any doubt, impressive for its extension and profoundity, as well as for its capacity to combine objective data with conceptual reflections about the scope and impact of the different perspectives concerning the theme of urban transformation and the different actors that have participated in such processes. The book weaves a broad net over the city, its history and development, adopting a multidisciplinary vision. I think that this will be the first step in creating a speech that might finally liberate itself from the strict disciplinary boundaries, building a trans-disciplinary perspective that can amplify the urban dimension of the city. This is the beginning of a profound and complex reflection that is, at the same time, a project of knowledge and an instrument of action and participation.

Water Consumption, Tariffs and Regulation aims to provide a statistical overview about water abstraction, consumption, tariffs and data on sewage and wastewater treatment at an international level. It is mainly based on the statistical information provided by IWA Specialist Group on Statistics and Economics. The book is structured in three main parts. Part I presents tables and figures relative to water consumption and sanitation status and focuses on water abstraction, water delivered, water consumption and the evolution of sewer connection and wastewater treatment. Part II focuses on the analysis of water tariffs by investigating the structure of water tariffs by analysing the importance of the variable and fixed charge. It presents drinking water tariffs and illustrates the relationship between tariffs and GDP and also the size of the cities. Finally, charges in wastewater are dealt with country by country. Part III analyses the main aspects relative to water regulation and describes the importance of private operators in the management of the water cycle. Information relative to the principles used to fix drinking water prices is presented with an assessment of access to public water services.

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.

In recent years, the increasing number of tourists traveling to specific urban and resort destinations has caused challenges for the effective management of tourism in these areas, with a resulting negative impact on towns, cities, and host communities. Such issues have included placing undue pressure on infrastructure; destruction of the physical, economic, and socio-cultural environment; and affecting the quality of residents’ daily lives by impacting their mobility and, in some cases, the price and rent of resident accommodation, goods, and services. To achieve a certain level of balance between the interests of local residents and visitors, new regulatory measures and legislation in high tourism areas must be discussed. TheHandbook of Research on the Impacts, Challenges, and Policy Responses to Overtourism is a collection of innovative research on best practices and legislation solutions for the management of tourism destinations suffering from overtourism, tourismophobia, or antitourism movement issues. While highlighting topics including overcrowding, social displacement, and tourism management, this book is ideally designed for local government officials, policymakers, lawmakers, researchers, entrepreneurs, industry professionals, travel agencies, hotels, academicians, and students seeking current innovative empirical research on destination-management practices and application techniques.
