RELAÇÃO ENTRE GASES DE EFEITO ESTUFA (GEE) E O USO DOS BIOINSUMOS NA AGRICULTURA: UM RELACIONAMENTO FRENTE À MERCADOS GLOBAIS EXIGENTES

Abstract

This study analyzes the relationship between the use of bioinputs and the reduction of greenhouse gases (GHG) in agriculture, focusing on the Brazilian cotton production chain. Using methodologies such as carbon balance, life cycle assessment (LCA), and mathematical models DAYCENT and DNDC, the research demonstrates that biological management systems can reduce GHG emissions by up to 25% compared to conventional systems. The results indicate that replacing chemical inputs with bioinputs promotes soil carbon sequestration (0.5-2 t CO₂/ha/year), reduces N₂O emissions, and decreases the total carbon footprint of production. Beyond environmental benefits, the adoption of bioinputs offers economic advantages such as cost reduction and access to demanding international markets, strengthening Brazil's position as a sustainable cotton producer. It is concluded that the integration of bioinputs into agricultural practices represents an effective strategy to mitigate climate change and increase the competitiveness of Brazilian agribusiness in the global scenario.
