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.

The multiple purposes of nature – livelihood for communities, revenues for states, commodities for companies, and biodiversity for conservationists – have turned environmental governance in Latin America into a highly contested arena. In such a resource-rich region, unequal power relations, conflicting priorities, and trade-offs among multiple goals have led to a myriad of contrasting initiatives that are reshaping social relations and rural territories. This edited collection addresses these tensions by unpacking environmental governance as a complex process of formulating and contesting values, procedures and practices shaping the access, control and use of natural resources. Contributors from various fields address the challenges, limitations, and possibilities for a more sustainable, equal, and fair development. In this book, environmental governance is seen as an overarching concept defining the dynamic and multi-layered repertoire of society-nature interactions, where images of nature and discourses on the use of natural resources are mediated by contextual processes at multiple scales.

The publication provides guidance principles for Life Cycle Assessment (LCA) databases; this includes how to collect raw data, how to develop datasets and how to manage databases. It also addresses questions concerning data documentation and review, coordination among databases, capacity building and future scenarios. LCA databases provide fundamental energy, materials, land, water consumption data and emissions data into water, air and soil for a wide range of processes, products and materials. In this way the publication provides the bridge between the data users and the data providers, making basic information easily accessible for computing the environmental footprints of materials and products that are key to make and judge green claims and to allow institutional and individual consumers to make informed consumption choices.

This book offers a detailed presentation of the principles and practice of life cycle impact assessment. As a volume of the LCA compendium, the book is structured according to the LCIA framework developed by the International Organisation for Standardisation (ISO)passing through the phases of definition or selection of impact categories, category indicators and characterisation models (Classification): calculation of category indicator results (Characterisation); calculating the magnitude of category indicator results relative to reference information (Normalisation); and converting indicator results of different impact categories by using numerical factors based on value-choices (Weighting). Chapter one offers a historical overview of the development of life cycle impact assessment and presents the boundary conditions and the general principles and constraints of characterisation modelling in LCA. The second chapter outlines the considerations underlying the selection of impact categories and the classification or assignment of inventory flows into these categories. Chapters three through thirteen exploreall the impact categories that are commonly included in LCIA, discussing the characteristics of each followed by a review of midpoint and endpoint characterisation methods, metrics, uncertainties and new developments, and a discussion of research needs. Chapter-length treatment is accorded to Climate Change; Stratospheric Ozone Depletion; Human Toxicity; Particulate Matter Formation; Photochemical Ozone Formation; Ecotoxicity; Acidification; Eutrophication; Land Use; Water Use; and Abiotic Resource Use. The final two chapters map out the optional LCIA steps of Normalisation and Weighting.
