EDITORIAL EDITORIAL Pedro Roberto Jacobi1 1Editor-in-Chief, Ambiente & Sociedade Journal Full Professor, Graduate Programin Environmental Science, University of São Paulo Full Professor, Education School, University of São Paulo This volume of Ambiente e Sociedade features nine articles that discuss alternative food networks, environmental conflicts in mining and hydroelectric projects, strategic environmental assessment, climate change adaptation and risk, reverse logistics, environmental services and recovery of degraded areas, associations in protected areas and social representation of sustainability. The construction of hydroelectric dams, and specially the forecast construction of more than 65 in the future is a key issue that Ambiente e Sociedade shares with its readers from the perspective of environmental justice. Since its inception in 1975, the construction project of the Belo Monte hydroelectric mobilizes Brazilian and international environmental movements and mainly local indigenous communities, triggering controversy, protests, conflicts and a sequence of reports and uncontested expertise. The choice of this energy matrix, is being questioned due to the negative impacts arising from the construction of large hydroelectric plants. [...]the process has been notified by reports of civil society organizations concerned with issues relating to environmental justice, which have shown the continuing lack of dialogue between the state and the scientific community, local communities and social movements. In "Risk, vulnerability and adaptation to Climate Change: An interdisciplinary approach" Allan Yu Iwama, Mateus Batistella, Lúcia da Costa Ferreira, Diogenes Salas Alves and Leila da Costa Ferreira feature based on the literature on the subject and a study case on the northern coast of São Paulo - Brazil, a vulnerability analysis under three interconnected axes (physical risk, vulnerability and social role).
