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 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, ...

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 applied geotechnologies to understand the cause and effect relationships between agricultural activities and greenhouse gas emissions processes, generating subsidies for management decisions that were agronomically and environmentally sustainable. For that, maps of pastures of the national territory were updated and geotechnologies were used to spatialize and monitor natural resources, human activities, and the consequences of these activities on the Earth's surface.

According to the Intergovernmental Panel on Climate Change (IPCC), a quarter of the national greenhouse gas (GHG) emissions comes from agricultural activities, and 93% of the CH4 emitted originates from enteric fermentation. Despite that, the agriculture practiced within given management standards can result in a lower GHG emissions. The GeoPecus project's goal is the application of geotechnologies for the understanding of the cause and effect relationship between agricultural activities and the

Data from 2006 the Agricultural Census indicate that the area of cultivated pasture in Brazil corresponds to about 106 million hectares. Since Brazilian cattle farming predominantly takes place in pastures, their degradation can represent economic and environmental damages for the sector. The process of pasture degradation is a complex phenomenon, which involves causes and consequences that lead to the gradual reduction of the pasture's support capacity. In order to adjust to the new environment

Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc

The experiment's goal is to study the interaction between nutrient availability and plant density over the production and allocation of biomass, nutrition and wood quality of homogenous populations of balsa wood ( Ochroma pyramidale )

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
