Perennial bioenergy grasses can restore Midwest soil carbon, but only within broader agro‑ecological reforms and policy shifts

The loss of soil carbon traces back to the Homestead Act of 1862, which incentivized rapid conversion of prairie to monoculture farms, and later to the 1930s Dust Bowl, which revealed the fragility of such systems. Subsequent New Deal policies and the rise of synthetic fertilizers entrenched corn‑soy dominance, further depleting organic matter. Understanding these policy legacies clarifies why simple crop swaps cannot reverse decades of systemic soil degradation without broader reforms.
The Midwest's soil carbon loss is a legacy of policy‑driven monoculture, dispossession of Indigenous stewardship, and market forces that prioritize short‑term yields.
Restoring carbon through perennial bioenergy grasses can succeed only when paired with reforms that re‑value ecosystem services, embed Indigenous land‑care practices, and provide equitable access to resources for marginalised farmers. Cross‑cultural examples from the Loess Plateau and Ethiopian highlands demonstrate that community‑governed, mixed‑species approaches yield resilient carbon gains while supporting livelihoods. By integrating scientific modelling, artistic engagement, and trickster‑style critical reflection, stakeholders can design a multi‑layered pathway that addresses climate mitigation, social justice, and cultural renewal.
