planetarie

Planetarie is a neologism used in speculative fiction and futurist discussions to describe a holistic, planetary-scale approach to the study and stewardship of planetary systems. In this sense, it combines elements of planetary science with considerations of governance, ethics, and long-term resilience of environments and populations.

In mainstream science, there is no widely accepted discipline called planetarie. The established terms include planetary science, geoscience, astrobiology, terraforming, geoengineering, and planetary governance; planetarie is used primarily in fictional or theoretical contexts to propose an integrated framework.

Core themes associated with planetarie include planetary habitability, climate dynamics, biosphere interactions, geologic processes, resource planning, planetary protection, and the design of sociotechnical systems that operate across an entire planet. The field- or conceptually oriented approach emphasizes systems thinking, sustainability, and intersubjective accountability across nations and cultures.

History and usage: The term has appeared sporadically since the late 20th or early 21st century in science fiction and futurist literature; it has no formal curricula or institutions, and its definitions vary by author or project.

Etymology: Planetarie appears to derive from planet and a suffix suggesting a field of study, but there is no standardized origin or pronunciation, and the term remains informal and contextual.
