Principles of Public Trust Thinking

Public trust thinking (PTT) offers a philosophical orientation toward natural resources and a means of addressing persistent and emerging challenges in environmental conservation. It has inspired laws and policies around the world and is receiving increasing attention among scholars and natural resource practitioners. Nevertheless, attempts to develop and implement PTT are hampered by lack of clarity: no clear single statement of principles that unite PTT’s diverse expressions exists. We address this need by synthesizing PTT literature across academic disciplines. We identify four areas that are in need of development and offer five principles that characterize PTT: (1) Human well-being is dependent on benefits provided by ecosystems; (2) Certain resources are not suitable for exclusive private ownership; (3) All beneficiaries are equal; (4) Future generations should be considered in current resource management decisions; and (5) Trustees are bound by fiduciary obligations and are publicly accountable.
