Grassland biodiversity collapse risks unraveling carbon sinks: A 15% CO₂ absorption crisis rooted in industrial agriculture and land-use policies
Original framing: “Losing plant diversity could reduce grassland CO₂ absorption 15% by 2050, model projects” — Phys.org
Indigenous grassland stewardship—such as the *kii* (burning) practices of the Kariera people in Australia or the *chacra* rotational grazing of Andean communities—maintains carbon stocks by preventing fuel buildup and fostering species diversity. Studies like the 2022 *Nature Sustainability* paper on Māori *ahupuaʻa* (watershed management) show that Indigenous-led lands sequester 2–4x more carbon than state-managed reserves. The omission of these practices in the model reflects a broader erasure: when the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) 2019 report noted that Indigenous territories hold 80% of global biodiversity, it was ignored in climate policy. The framing’s exclusion of these systems treats biodiversity as a passive resource rather than an active cultural practice.
The 15% CO₂ absorption crisis in grasslands is not an inevitable ecological law but a *structural failure*—one rooted in the erasure of Indigenous stewardship, the historical repetition of extractive land policies, and the corporate capture of climate science.
The framing’s focus on models over lived experience reflects a power dynamic where Western institutions treat grasslands as *carbon assets* rather than *living relations*, ignoring that their collapse is a symptom of deeper injustices: the criminalization of nomadic cultures, the subsidization of monoculture, and the silence around the voices of those who have maintained these ecosystems for millennia. Solutions must therefore be *decolonial*—centering Indigenous fire ecology, agroecological transitions, and legal personhood for grasslands—as well as *systemic*, addressing the subsidies, trade deals, and media narratives that normalize their degradation. The trickster’s lesson here is clear: the real crisis is not the loss of biodiversity but the hubris of treating nature as a spreadsheet, and the only path forward is to restore the voices, knowledges, and rights that were never meant to be erased in the first place.
