Historically, the agricultural activities in the northeast of Pará have been concentrated in the hands of small farmers and family-based workforce, who dedicate themselves almost exclusively to subsistence farming with focus on yuca (Manihot esculenta), corn and caupi-beans (Vigna Unguiculata) as crops with most significant socio-economic expression. This practice is done with little or no use of agricultural supplies, such as lime and fertilizers, leading the region's lands, which already have ...

This research project aims to study organic sugarcane cultivation areas of the Santo Antônio Sugar Mill in Sertãozinho, São Paulo, with emphasis on mapping and characterizing the current status of the vegetation within Permanent Preservation Areas (APPs, from the acronym in Portuguese), for the implementation of an agro-ecological project. The research project should promote an increment to the faunal biodiversity and production systems in such properties, helping the dispersion of seeds along t ...

This project aims to recover legal reserve areas (ARL) or areas of permanent preservation (APP), in regions of family agriculture at the Brazilian Oriental Amazon, in the hopes of reducing impacts resulted from agricultural and forest practices. The project aims to train at least 150 family farmers in management of natural resources in areas which are close to bodies of water, and also to recover and monitor these areas' environment. The project will be developed in micro-basins of the Bragança, ...

Sustainability of traditional cultivation systems (slash-and-burn) depends especially on long periods of set-aside in order to reestablish the stock of the soil's nutrients and raw organic material used and/or lost during the agricultural period. Population growth and decrease in the region's secondary vegetation availability has progressively reduced the set-aside period, subsequently increasing the pressure on riparian areas and cultivated ones. The result if degradation of natural resources a

Com o objetivo principal de aumentar a qualidade e a produtividade da maçã brasileira, foram gerados subsídios importantes ao setor produtivo para o estabelecimento de tecnologias apropriadas ao manejo da planta e do fruto. Além disso, foram desenvolvidos estudos fundamentais relacionados aos aspectos moleculares e fisiológicos da qualidade do fruto, visando ampliar conhecimentos acerca de fenômenos que ocorrem nas frutas durante sua vida pós-colheita. Em termos de resultados principais, destaca ...
