摘要: Este artigo tenta enfatizar a importância das tendencias e desafios dos impactos da agricultura sobre o ar agua. Dentre os componentes poluidores do que devem ser monitorados temos metano, oxido nitroso, nitrico, amonia, dioxido de carbono, sendo estes gases podem contribuir para mudanca climatica eutrofizacao e acidificacao. No caso da poluicao agua, devemos considerar seriamente esgotamento dos lencois freaticos, alagamentos salinizacao, por fertilizantes pesticidas manejo inadequado rebanhos. A experiencia paises desenvolvidos pode servir alerta aos paises em desenvolvimento no diz respeito aos impactos agro-ambientais, pois estes adotam padroes intensidade uso bastante similares aqueles. Diversas medidas estao sendo tomadas estudadas carater regulatorio, economico tecnico pelos paises desenvolvidos frear ritmo expansao diversos tipos de degradacao
