There is currently a strong interest to comprehend, evaluate and minimize anthropic impacts on hydric resources. It has been particularly studied the effect of removing native vegetal covering over water availability and quality. In order to estimate the effects of changing vegetal covering over hydric resources, hydrologic modeling becomes an adequate tool. However, hydrologic models need great amounts of information, which in most times are unavailable. On the other hand, data obtained through

This project aims to evaluate the productive potential of explored forest areas after one cutting cycle (30 years) and propose a forestry management system for the second cutting cycle in the Amazon. Technological ability and floristic variety of arboreal species will also be evaluated, in areas previously submitted to forest exploration 30 years ago (Tapajós National Forest). This project, headed by Oriental Amazon Embrapa in partnership with Federal Rural University of the Amazon, aims to deve ...

Despite agri-business's great importance, our principal products are exported in the form of commodities, without any quality specification. In order to commercialize them with quality attributes, it is necessary to make use of processes of quality determination and certification, at low costs, so that the price of the analyzed product won't rise significantly. Thus, it is necessary to develop ultrafast sensors that allow the analysis of thousands of samples an hour and non destructively, which

Precision farming and agricultural practices that take into consideration the protection of the environment have brought forward a number of research challenges. The scale of sampling and the precision required by such new agricultural practices are often higher than those required by traditional agriculture, increasing production costs. Methods and devices for on-the-go measurements are being developed to equip agricultural vehicles to support these practices. The proposed project was guided

Promoting the diffusion of integrated peanut production practices, with emphasis on the biological control of fungi to reduce product contamination by aflatoxin in Mali, is the goal of this project. The action has made the knowledge exchange between Brazilian and African researchers possible. Mali is the second largest peanut producing country of the African continent. However, the product's high contamination rates in the country affect the crops and cause health risk for consumers. As an alter

Legal norms and market behavior demand a new posture when facing the environment of various economical factors. In the forest sector, this posture has been defined through the restructuring of the use and occupation of cultivated areas with commercial forests, promoting the environmental compliance of productive activities. This reorganization of rural areas, and areas of permanent preservation and legal reserves which were improperly occupied by forest activities, and thus opposing current legi

This project's goal is to evaluate and quantify the impacts caused by global climate changes in Brazilian's most important economic cultures . For such a purpose, the input database of all the models of all the proposed projects will consist of projections or regional scenarios released by the Intergovernmental Panel on Climate Change (IPCC), and serve as downscalings of the global climatic scenarios. These regional scenarios will define future agricultural scenarios based in mathematical models
