Life cycle thinking in graduate education: an experience from Brazil

PurposeThis study presents an educational experience, of a Brazilian center of technological education, focused on the involvement of undergraduate and graduate students, according to directions of UNEP/SETAC Life Cycle Initiative. It describes an institutional collaborative work, aligned with the Life Cycle Initiative, and evaluates the main actions implemented through a set of indicators, which show the organizational dynamics and changes in the professional profiles of students, between 2006 and 2012.MethodsThe description of the institutional collaborative work was based on direct observations conducted by the authors, who participated in the experience, and on a documentary research involving data from academic system. This effort led to representations of (a) key interactions among actors of organizations and (b) a set of 11 indicators of changes for individuals and organizations. Interviews with students and representatives of organizations also contributed to generate the structure of the network and to fulfill the set of indicators.Results and discussionAmong the research findings, two were considered more relevant from the direct observation: (a) the structuring of an effective laboratory supported by public funds to conduct the educational experience and (b) the introduction of life cycle thinking (LCT), life cycle management (LCM), and the methodology of life cycle assessment (LCA) as optional areas of study for students. The offer of regular classes, supported by software, and the organization of small-scale research projects made the work feasible, altogether, improving the interest and cooperation of different graduate and undergraduate student groups. This outcome increased the interactions with other public and private organizations; much additional research was accomplished.ConclusionsThe experience contributed to materialize the LCT, LCM, and LCA themes and persuades the actors to reflect on new reflections concerning the necessity of changes in their professional profiles. This suggests a potential to produce organizational improvements and innovations. However, some challenges must be faced in Brazil: organization of the national inventory, improvement of academic knowledge and more engagement of scholars, as well as the lack of guidance and assistance to consolidate local and national collaborative work.

Study of the sustentability indicator ecological footprint: a theoretical-empirical approach

Neste artigo, tem-se como objetivo descrever a metodologia da Pegada Ecologica (Ecological Footprint), uma ferramenta para medir, comunicar e comparar o desenvolvimento das nacoes, utilizando uma fundamentacao teorico-empirica por meio de uma pesquisa bibliografica realizada na literatura especializada. Este estudo aborda, inicialmente as definicoes, as premissas adotadas, o metodo para o calculo do indicador e as principais vantagens e desvantagens da utilizacao do metodo da Pegada ecologica. Os resultados obtidos para este indicador, em diferentes paises, revelam que o Brasil possui um superavit ecologico, que permite o desenvolvimento social e economico com a conservacao dos recursos naturais.
