Improving livestock health reduces emissions by addressing systemic feed, land, and welfare practices worldwide

Lifecycle assessments demonstrate that improving animal health can reduce enteric methane by 5‑15 % through better digestion efficiency, yet the net climate benefit depends on feed composition, manure management, and land‑use change. Recent meta‑analyses highlight the importance of integrating veterinary interventions with feed‑quality upgrades to achieve measurable emission cuts. Robust, open‑source modelling platforms are needed to capture these complex interactions at regional scales.
A systemic lens reveals that improving livestock health cannot be isolated from the broader agro‑ecological, economic, and cultural matrices that drive emissions.
Historical subsidy regimes, corporate supply chains, and global trade policies have entrenched high‑intensity dairy systems, while Indigenous and marginalised practices offer alternative pathways rooted in ecological balance. By integrating scientific lifecycle assessments with Indigenous grazing wisdom, fostering transparent value chains, and reshaping policy incentives, we can align animal welfare with genuine climate mitigation. The trickster insight warns us to remain vigilant against narratives that disguise power preservation as progress, ensuring that reforms truly redistribute benefits across societies and ecosystems.
