GenesisAeon Package 126 — real biodiversity-driver ranking science, connecting existing GenesisAeon packages to the official IPBES driver framework. Deliberately has no UTAC/CREP/AFET bridge — see DISCLAIMER.md.

For a plain-language explanation of the same topic (German, no jargon, written for general audiences), see WHITEPAPER.md.

Where this package came from

Surfaced via a six-document multi-AI gap-analysis of the GenesisAeon climate/ecology portfolio (KlimaAktuell/, 2026-09-01), then independently deep-dive verified before building — the last of a five-package batch alongside ocean-acidification-utac (P122), tropical-glacier-ecosystem-rle-utac (P123), marine-compound-stressors-utac (P124), and assisted-gene-flow-utac (P125). Deliberately a relation package: it documents which existing GenesisAeon package — amazon-utac (P19), freshwater-ecosystem-stressors-utac (P106), mixed-forest-resilience-utac (P113), and biodiversity-utac (P115) — is actually about which official IPBES direct biodiversity driver, something none of those packages currently states explicitly.

What's real here

• IPBES Nexus Assessment (approved 2024-12, Windhoek, Namibia, 165 experts + 70 contributing authors) — the official list of five direct biodiversity drivers: land/sea-use change, direct exploitation, climate change, pollution, invasive alien species.
• Jaureguiberry et al. (2022, Science Advances) — a real, quantitative systematic synthesis: on land and in freshwater, land/sea-use change is the dominant driver, direct exploitation ranks second, pollution third — climate change and invasive species are significantly less important overall in these realms.

Deliberately not one-sided

is_land_use_dominant_in_every_realm() returns False — in the ocean realm, the ranking reverses: direct exploitation and climate change dominate instead, a real, documented realm-specific reversal of the land/freshwater ranking. There is no single global driver ranking that applies everywhere.

Quickstart

pip install climate-landuse-biodiversity-nexus-utac

from climate_landuse_biodiversity_nexus_utac import (
    land_freshwater_driver_ranking,
    ocean_dominant_drivers,
    primary_driver_for_package,
    is_land_use_dominant_in_every_realm,
)

print(land_freshwater_driver_ranking())
# ('land/sea-use change', 'direct exploitation', 'pollution')
print(ocean_dominant_drivers())
# ('direct exploitation', 'climate change')
print(primary_driver_for_package("amazon-utac"))  # 'land/sea-use change'
print(is_land_use_dominant_in_every_realm())  # False
