Systemic overshoot: Global population growth driven by extractive economies threatens planetary boundaries and equity

Indigenous worldviews universally frame human population as one thread in a larger ecological tapestry, where balance is maintained through reciprocal relationships rather than control. Systems like the Amazon’s *terra preta* soils or the Māori *marae* governance demonstrate sustainable coexistence with high biodiversity despite dense populations. Western demographic models ignore these precedents, instead framing growth as a mechanical problem requiring technical fixes like contraception or migration restrictions.

Colonial expansion (1500–1950) redistributed 90% of global wealth to Europe while depopulating continents through disease and genocide, creating artificial 'empty lands' for settler economies. Post-WWII development models (e.g., Green Revolution) prioritised export crops over subsistence, displacing 500 million people and accelerating land degradation. The 1970s 'population bomb' discourse mirrored colonial fears of non-white fertility, used to justify sterilisation campaigns in India and forced family planning in Latin America.

In Kerala, India, high literacy and gender equity achieved through communist governance reduced fertility rates to 1.7 without coercion, proving that education and women’s autonomy—not austerity—stabilise populations. The Islamic principle of *khilafa* (stewardship) and the African concept of *ubuntu* (interconnectedness) both reject the commodification of life, offering alternatives to Western growth paradigms. Meanwhile, China’s one-child policy, despite reducing fertility, created a demographic time bomb and social crises, illustrating the failures of top-down control.

Planetary boundaries research (Rockström et al., 2009) identifies nine critical thresholds, with climate change, biodiversity loss, and biogeochemical flows already exceeded. The 'IPAT' formula (Impact = Population × Affluence × Technology) is critiqued for obscuring power dynamics; affluence (consumption per capita) is the dominant driver in high-income nations. Studies show that 50% of global emissions stem from 10% of the population, while the poorest 3.5 billion contribute <10%.

Artists like Agnes Denes (*Wheatfield—A Confrontation*) and indigenous poets such as Joy Harjo (*How We Became Human*) reframe population as a crisis of imagination, not biology. Spiritual traditions from Sufism to Zen warn that attachment to growth (*tanha*) leads to suffering (*dukkha*), while creation myths (e.g., Māori *Ranginui* and *Papatūānuku*) depict humanity as kin to the land, not its conqueror. These perspectives challenge the Cartesian separation of humans from nature that underpins modern demographic discourse.

Scenario modelling by the Stockholm Resilience Centre shows that stabilising population at 9 billion by 2050 requires reducing per-capita consumption in the Global North by 75% while increasing it in the Global South—achievable through degrowth policies and wealth taxes. Alternative futures include 'ecological swaraj' (Gandhian self-rule) or 'bioregional democracy,' where governance aligns with ecological limits. The most plausible collapse scenarios (e.g., +3°C warming) predict 1 billion climate refugees by 2050, disproportionately affecting high-fertility regions, but these are not inevitable.

Women of colour, particularly in the Global South, bear the brunt of population control narratives, with sterilisation campaigns in Peru (1990s) and India (2010s) targeting indigenous and Dalit communities. Climate refugees from Bangladesh or Pacific Islands—whose per-capita emissions are <1% of a U.S. citizen’s—are framed as 'overpopulating' rather than as victims of colonial carbon debt. The 'demographic dividend' myth justifies austerity in Africa, ignoring that 60% of the continent’s land is controlled by foreign agribusinesses.
