O desenvolvimento da agricultura brasileira pode ser caracterizado pela incorporação contínua de novas terras. Um sinal de mudança nessa dinâmica ocorre a partir da institucionalização do Paradigma do Desenvolvimento Sustentável. Contudo, ainda persiste o avanço da fronteira agrícola, mas agoraamparado pelo uso intensivo de capital e tecnologia. Nesse contexto, o objetivo principal deste estudo é explorar a dinâmica agricultura e meio ambiente no Brasil a partir de uma perspectiva econômico-ecológica e histórica. O estudo adota uma abordagem qualitativa-exploratória, mas acompanhada de dadosestatísticos, a fi m de reforçar a análise da agricultura e sua interface ambiental no Brasil. Apesar do avanço tecnológico e das práticas de manejo no Brasil, não há sinais de reversão da tendência de degradação ambiental, ameaçando a sustentabilidade de longo prazo da agricultura.

N° ISBN - 978-2-7380-1284-5 ; International audience ; This paper has the aim to contribute to the Public Policies definition to the sustainable management of the environment hydrological services in watershed. Due to the freshness of the theme we show a particular methodology for the diagnostic phase of an ecosystem service based on the failure institutional framework merger (transaction, empowerment and government) of J. Opschoor (1992) theory and the methodology of analyses towards a tree of problems. This proposal was applied in a case study which was development in Peru, in 2009. The results were: An analyze of what happened in Andinos Countries and in Peru regarding the payments of environment hydrological services. The payment of environment hydrological services constitutes a strategy to transform the sustainable management of environment hydrological services in watershed, in a dynamic management. Then, it creates an acknowledgement to the families who are in these service areas, making them more sensitive to the need to protect these services. More than a real appreciation of the environmental services, it is a consensual means of economic resources generation which permits to make the society more sensitive, compensating the committed to environmental protection, promoting understanding actions of others ecosystem services and putting them in the market with value. The diagnostic methodology constitutes in an instrument of integral character, even the possibility to use in other environmental management researches, due to its integral character. There are elements to the definition of regulatory public policy to the hydrological environmental services in a logical sustainable management of the area (watershed)
