Ecological economics
A transdisciplinary field treating the economy as a subsystem of the finite ecosphere — founded institutionally by the ISEE and its journal in 1989.
Expert review openNo editor-accepted expert review yetDefinition
Ecological economics is a transdisciplinary field that studies the economy as embedded in and constrained by the Earth's ecological systems, addressing scale (physical limits to throughput), distribution (equity) and allocation (efficiency) together. Founded institutionally with the International Society for Ecological Economics and its journal in 1989, its intellectual lineage runs through Kenneth Boulding, Nicholas Georgescu-Roegen and Herman Daly, whose steady-state economy remains a defining model. It differs from environmental economics by grounding analysis in biophysical limits rather than assuming substitutability of natural capital.

Overview
What it means
Economics rebuilt on thermodynamics and ecology: the ecosphere is the containing system, not a sector of the economy.
How it is used
The field underpins natural-capital accounting, strong sustainability, degrowth scholarship and critiques of GDP as a progress measure.
Why it matters
Ecological economics supplies the theoretical foundations for planetary-boundaries thinking, wellbeing economies and post-growth policy debates.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
