🔬研究者:Integration of pasture management, by-products, and ICLF systems as complementary strategies; need for more in vivo and commercial-scale trials.

🏢実務担当者:Potential use of Amazonian fruit by-products (e.g., açaí seed cake) as feed additive to reduce methane, though evidence is preliminary.

🏛政策担当者:Support for integrated land-use policies that combine soil carbon sequestration, deforestation avoidance, and livestock mitigation in tropical regions.

Livestock production is a major contributor to greenhouse gas emissions, particularly enteric methane, and requires mitigation strategies that are compatible with sustainable intensification, regional development, and climate resilience. This review provides an integrated analysis of pasture management, Amazonian agro-industrial by-products, and integrated crop–livestock–forestry (ICLF) systems as complementary strategies for low-emission livestock production. Rather than addressing these approaches separately, the article proposes an integrated perspective in which soil carbon sequestration, enteric methane mitigation, circular bioeconomy, and deforestation avoidance are interpreted as interconnected components of sustainable livestock systems. Current evidence suggests that well-managed pastures can increase soil carbon stocks, improve land-use efficiency, reduce emission intensity per unit of animal product, and alleviate pressure for new deforestation. Amazonian agro-industrial residues, especially those derived from tucumã, cupuaçu, buriti, and açaí, show potential nutritional and functional value, particularly when used as lipid-rich oils or seed cakes capable of modulating ruminal fermentation. However, evidence supporting the methane mitigation effects of Amazonian oils and co-products remains limited and is mainly based on a small number of in vitro assays and small-scale in vivo studies. Therefore, additional animal trials, standardized inclusion levels, and long-term assessments under commercial production conditions are still required before broad practical recommendations can be established. ICLF systems further strengthen this mitigation pathway by combining productivity gains, carbon accumulation, restoration of degraded areas, and ecological diversification. Overall, the integration of pasture management, Amazonian co-products, and diversified production systems represents a promising strategy for transitioning toward more resilient and low-emission livestock systems in tropical regions.
