Why Ecological Economics Calls for Degrowth

It argues that infinite growth on a finite planet is impossible.
So it favours degrowth, steady-state, or slow growth, especially in high-income countries.
The aim is to keep human demand within the Earth's biocapacity.

Three Post-Growth Models

Degrowth
1. A planned reduction in consumption and production that eases environmental pressure while protecting wellbeing.
Steady-state (zero growth)
1. A stable economy that holds resource use within regenerative limits and redistributes rather than accumulates.
Slow growth (post-growth)
1. Gradual growth kept within ecological limits through efficiency and clean technology.

Example

Bhutan's Gross National Happiness index measures wellbeing, culture, and sustainability instead of GDP.

Footprint vs Biocapacity: The Core Balance

The ecological footprint is the demand human activity places on ecosystems.
Biocapacity is the Earth's ability to regenerate resources and absorb waste.
