Boundary work in climate policy making in Brazil: Reflections from the frontlines of the science-policy interface

Despite challenges to the authority and legitimacy of science as a neutral representation of the world, expert advisors are playing an increasingly central role in environmental policy-making in both the Global North and South. This article explores the science-policy interface, based on the experience of the main author as a scientist and policy-maker at FEAM, a state-level environmental agency in Brazil. Contributing to the literature on boundary objects and organizations, the article details the practices necessary to manage the relationship between political and scientific norms in the development of the regional Climate and Energy Plan (CEP) for the state of Minas Gerais. To sustain the role of FEAM as a boundary organization mediating between political and scientific demands, a team of scientists and policy-makers had to perform different types of boundary work in a closely connected manner. It was necessary to actively frame climate change as an economic problem, and structure its solution in terms of mitigation mechanisms. Responding to changes in the national and international political context, FEAM reframed climate change from mitigation into largely an adaptation issue that could lead to win-win solutions as to attain saliency and avoid insurmountable political obstacles for its approval. Based on this experience, the article argues that the performance of boundary objects and organizations in the science-policy interface not only requires an ability to bring ‘truth to power’ but to also the capacity to sense, anticipate and avoid political obstacles. For this reason even though boundary organizations provide a breeding ground for institutional learning it is an unsuitable location for scientific or political revolutions.     

Environmental policy indicators: A systems model

This article describes and tests a systems theory-based policy indicators model. The framework is used to examine propositions about linkages between states' ecological-spatial characteristics and subsequent selected solid waste management (SWM) -related environmental policies. It was hypothesized that state characteristics of: (1) population density (used as a garbage-per-land area index), (2) population convergence within urban areas, and (3) percent population change in the interval 1980–1985, could jointly explain state variation in both the number and the vigor of SWM policy outputs. Greater levels of spatial pressure were proposed to be related directly to more numerous, more convincing policies. Proposals are grounded in the literature of organizational search theory, crisis stimulation, and technological pressure. Results revealed that the sociospatial model in fact could explain a reasonable proportion of policy variation across states. However, not all hypotheses are supported. Population change shows an indirect, rather than the anticipated direct, relationship with policy output levels. In addition, when used in the model as a pollution intensity index, population density failed to contribute significantly to an explanation of differences in state SWM policy levels. The analysis raises questions about changes occurring over time in the nature and direction of linkages between sociospatial measures and policy responses. This study suggests that strengthening policy indicator models may require questioning key assumptions and theoretical bases, conducting longitudinal studies, and factoring in political, economic, and other policy environment forces.
