A geografia agrária brasileira: dinâmica, variada e complexa

This paper is a contribution to the debate on the methodological issues surrounding the Land Geography, demonstrating why the Brazilian Agrarian Geography is dynamic, varied and complex. It was chosen as the theme of Research Groups in Geography Agrarian present in Directory Groups CNPq and they held on a characterization considering: home institution, location, year of training, Group name, words and lines of research. The survey allowed the treatment of 70 groups in 2009 had the agrarian geography, agriculture, rural development, rural, rural areas, organization of space and rural development as guiding their research and performances. The analysis of the research lines identifi ed groups concerned with economic, political, ecological, demographic and cultural, and also found concerns with farmers, with their production and the functioning of the agricultural system, being thus, the set of raised lines one can say that there is signifi cant diversity in themes, which reinforces the hypothesis of dynamism, variety and complexity of studies on agriculture today.

Indicadores de sustentabilidade para conservação genética de Erythrina velutina Willd., em área de mata ciliar

One of the greatest challenges for the agricultural system is to establish agricultural production combined with the conservation of genetic resources, mainly aiming to protect the Permanent Preservation Areas. In this context, mulungu ( Erythrina velutina Willd), among other native species, has been suffering with anthropogenic pressures in various ecosystems, causing reductions in its genetic basis. This work aims to identify ecological and genetic population parameters as indicators of sustainability in two natural populations of mulungu, located in riparian forest, in the state of Sergipe, and to assess the tendency to their sustainability, aiming genetic conservation of the species. The matrix of Pressure-State-Impact/Effect-Response (PEI/ER) was used with the selection of 13 indicators, from the use of RAPDmolecular markers and biochemical (enzymes) markers in populations, in order to present them as relevant information to measure progress as for sustainability and conservation ofmulungu. The studied populations presented low tendency to sustainability, requiring strategies to change this status.
