Using land-use models in deliberative planning is promoted as an example of how environmental decision-making can be subject to both: 1) facts about how the interaction between human action and natural processes; and, 2) local perspectives on how land-use planning processes can incorporate normative concerns. This ‘normative’ input is often shaped and limited by the presentation of the modelled facts. This paper, however, shows that the selection and measurement of indicators, the primary outcomes of modelling exercises, are subject to a (...) highly particular assessment, influenced by social factors, political choices and technical limitations. This revised understanding does not invalidate the use of models in participatory planning. But it does open up considerable space for stakeholders in deliberative contexts to question and challenge the evidence-based policy implications of so-called ‘fact-based’ modelling exercises.

ArgumentThis article studies the roles three science-based models play in Dutch policy and decision making processes. Key is the interaction between model construction and environment. Their political and scientific environments form contexts that shape the roles of models in policy decision making. Attention is paid to three aspects of the wider context of the models: a) the history of the construction process; b) the political and scientific environments; and c) the use in policy processes over longer periods of time. Models (...) are more successfully used when they are constructed in astablepolitical and scientific environment. Stability and certainty within a scientific field seems to be a key predictor for the usefulness of models for policy making. The economic model is more disputed than the ecology-based model and the model that has its theoretical foundation in physics and chemistry. The roles models play in policy processes are too complex to be considered as straightforward technocratic powers. (shrink)

This paper explores the context of environmental justice (EJ) in Scotland, and presents a case study whereby the main attributes for an indicator of EJ were identified, encompassing procedural and distributive aspects of justice. Through a participatory process, weights were assigned using a Multi-Criteria Analysis tool, the Analytical Hierarchy Process (AHP). Results show that overall, environmental injustices are mostly associated by respondents to unequal distribution of health burdens due to pollution, yet greater weight is attached to procedural justice by community (...) environmental activists. The paper suggests that AHP may be applied to many situations and could form a basis for the development of tools to address and deliver EJ in Scotland. (shrink)
