In this theoretical chapter, we argue that management of contaminated sites cannot be understood separately from the institutional context that binds these processes. Within the policy sciences, rational choice institutionalism is presently the dominant scientifi c paradigm in studies of the relationship between institutions and the outcomes of environmental management processes. However, in order to analyze contaminated sites management in modern democracies, we found it necessary to partially depart from this mainstream. We argue that there is in rational choice institutionalism a problematic oblivion of power and politics that leads to institutional determinism, a neglect of actor processes in environmental decision-making that produces causal reductionism, and a weak understanding of the socio-legal nature of institutions, which does not allow one to fully grasp the changes to environmental management that relate to the governance era. Therefore, we present our own theoretical framework that combines institutional analysis and policy process analysis, in order to study the politics of contaminated sites. Drawing from the literature on institutional regimes, policy process theories and network analysis, we discuss several research hypo theses on what might infl uence the environmental performance of contaminated sites management.The management of a contaminated site is embedded in an institutional context that must be apprehended in order to understand the processes involved in ecological management. The work of renowned Anglo-Saxon scholars like Elinor Ostrom ( 1990 ) has contributed to demonstrate that besides economic and macro structural factors such as the GDP or the population, institutions are fundamental research objects to understanding why natural resources are under stress, and how ecosystems are actually managed.Among the various approaches to institutional analysis that deal with environmental management, rational choice institutionalism (Ostrom, 2007b ) has been the most fruitful analytical framework. However, in order to analyze contaminated sites management in European countries, and to account for the changes related to the governance era, we found it necessary to partially depart from this mainstream out of several reasons that will be discussed below, before we introduce our own theoretical framework.
A Critical Perspective on Rational Choice InstitutionalismFirst, institutions and governance, which are some of the most basic theoretical notions that underpin rational choice institutionalism, have become so widely used that they can be considered as "magic words" (Pollitt & Hupe, 2011 ) under which contradictory meanings are confl ated. Notwithstanding the vagueness of the term of "institution" and the frequent confusions between the concepts of institute, organization, policy, regulations, formal and informal rules which can all be referred to as "institution", at least four different theoretical perspectives on institutions exist, each with singular understanding of the meaning, s...
