A mathematical framework for dissecting the normative foundations of conservation decisions
A mathematical framework for dissecting the normative foundations of conservation decisions
Abstract Perspectives in conservation are based on a variety of value systems and normative postulates. Such differences in how people value nature and its components lead to different perceptions of the morality of conservation goals and approaches, and often underlie disagreements in the formulation and implementation of environmental management policies. Specifically, whether a specific conservation decision (e.g. killing feral cats to save birds threatened with extinction) is viewed as appropriate or not can vary among people with different value systems. Here, we present a conceptual framework that mathematically formalises the interplay of value systems. This framework is intended to serve as a heuristic tool to clarify normative postulates in conservation approaches, and it highlights how different value systems can lead to different prioritizations of available management options. We compare how management decisions would likely be viewed under three different idealised value systems (ecocentric conservation, new conservation, and sentientist conservation). We illustrate the utility of the framework by applying it to case studies involving invasive alien species, rewilding, and trophy hunting. By making value systems and their consequences in practice explicit, the framework facilitates debates on contested conservation issues. Finally, we believe dissecting the normative postulates of conservation decisions will facilitate understanding and addressing conservation conflicts.
