Articulação entre política agrícola e ambiental: uma análise do caso brasileiro

O modo de produção agrícola vigente é causador de impactos ambientais. Estes impactos podem ser representados, por exemplo, pela devastação de matas e florestas com o intuito de expandir a fronteira agrícola, a erosão do solo e a poluição das águas, da terra e do ar. Este trabalho mostra que a relação entre a atividade agrícola e o meio ambiente não precisa ser litigiosa, podendo conviver de forma harmônica. Para isso, foram estudados os programas criados pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA) que articulam as políticas ambientais e agrícolas em prol do desenvolvimento sustentável. São exemplos destes programas a Integração Lavoura-Pecuária-Floresta (ILPF), o plantio direto na palha e o programa Agricultura de Baixo Carbono (ABC)

Crise da cafeicultura e seus efeitos socioeconômicos no município de Dracena (SP)

The coffee crisis in the 1980s reached deeply municipality of Dracena, considering that the coffee had significant social and economic importance to the area. In this context, the research aimed to analyze the socioeconomic consequences that this crisis has provided small rural proprietors of the county. To achieve this goal we seek to articulate the theoretical reference, with data from secondary sources, interviews with the main responsible for the agricultural sector and an application questionnaire to 21 small rural proprietors of the county. It was found that, due to the dependence relationship with the coffee, the economy of the city suffered from the attack of said culture during the 1980s. Rural producers who cultivated such crops as the main, had to readjust productively to remain in the countryside, but the economic and social development that coffee was brought in earlier times was not rescued. As a consequence, there has been an intensification of evasion demographic of rural municipality, a process that had begun in the 1970s and was strongly reinforced by the crisis of the coffee culture. We note that from the 2000s, the situation became better for small rural proprietors in order that public policies implemented now serve, in part, the needs of those with greater efficiency. This situation can be evidenced by a slight reduction in the number of rural people dracenense. Despite improvements recorded since the 2000s, the situation is still not ideal, given that many small proprietors surveyed expressed dissatisfaction. In this context, we note that the performance and joint of federal, state and municipal government are essential so that public policies are efficient, thus providing decent conditions for social reproduction of small rural proprietors and their dependents in the countryside

Desempenho e uso eficiente da terra de modalidades de consorciação com milho e forrageiras

This study was developed with the aim of evaluating the performance and land use efficiency of different arrangements of intercropping with maize and forage. The field experiment was conducted in Tangar da Serra/MT. The experimental design was a randomized block in factorial scheme 3x2 + 1, were as three arrangements of intercropping, two species of forage and an additional treatment with maize monoculture in four replication. In maize monoculture and intercropping were evaluated: plant height and ear insertion height, plant population, weight of 100 grains, productivity, number of grain rows and number of grain per row. In forages intercropping with maize were evaluated plant population and dry matter accumulation. The arrangements with Maize + Forage sown in the line and Maize + Forage sown in two rows between rows with the species Urochloa hybrid promoted best corn yields. The modality and species affect both the productivity of maize as forages species. Grain yield of maize is higher in monoculture. The higher dry matter accumulation of Urochloa hybrid occurs in the Maize + Forage sown in one row between rows, while, for the Urochloa brizantha the arrangements studied do not affect their yields. The arrangement with best land use efficiency is Maize + Forage sown in two rows between rows for both study forage species.
