Environmental studies have developed slowly within social sciences in Latin America. This paper seeks to assess and systematize the contribution of social sciences in the research on the human dimensions of global environmental change (HDGEC) in the region outlining its state of the art and process of development.

The approach taken is the organization of a manual compilation and systematic review of publications on topics related to the HDGEC in order to investigate major research topics covering the period between 2001 and 2008.

Although it is possible to identify an emergent body of the literature and scholarship in the region, the involvement of Latin American social science in the HDGEC research is still timid and tentative and not yet institutionalized. The evidence from this compilation has shown that this literature is fragmented bringing difficulties for the homogenization of criteria for analysis and assessment.

The paper is one of the very few attempts to assess and analyze the research on HDGEC in Latin America through an international perspective. It provides an overview of its development building upon the progress of environmental studies in the region and looks to its challenges ahead in order to call for more involvement of social sciences in these research activities.

The purpose of this paper is to analyze the factors shaping climate policies in two megacities in Brazil – São Paulo and Rio de Janeiro – through a multilevel perspective. The paper seeks to explore how climate change is being framed and how local governments are responding to it in terms of policy strategies.

Through empirical research based on two case studies, the authors discuss the governing of climate change action and analyze the factors that can constrain or undermine these actions based on information collected from reports, institutional web sites and academic and newspaper articles.

The participation in transnational municipal networks has been central for promoting and supporting climate change actions in both cities following the international experience. The organization and implementation of climate change measures rely on a landscape formed by multiple actors often spanning several sectors and levels of governance.

Most of the literature on climate change policy at the local level focuses on the context of developed countries. Analyses of advanced developing countries like Brazil are sparse as well as comparison in light of the international experience. The paper also draws attention for the lack of awareness for adaptation at the local level in these countries, building upon recent scientific findings on global climate change.
