Embrapa Satellite Monitoring, in a partnership with Indiana University (USA), coordinated the research project "Human and Physical Dimensions of Land Use/Cover Change in Amazônia: A multi-scale synthesis”. The project ended in 2010, and was part of the Large-Scale Biosphere-Atmosphere Experiment in Amazônia (LBA). The research encompassed seven study areas and made a transversal analysis of the social and biophysical dimensions of transformations in the Amazon landscape. Rural settlements wer

This project has developed approaches of analysis, categorization and disclosure of information regarding agricultural development in centers with expressive production of soy and sugarcane, and with focus on their relationship between land use and occupation dynamics, agricultural practices and other environmental and socio-economic variables. In the agro-environmental sense, the analysis and mapping were focused in processes of agricultural development, highlighting the importance of the secon

A country's sovereignty is directly related to ensuring the three types of security: food, energy, and territorial security. Basically, food security and renewable energy security depend on agriculture and its water resources. Brazil, which contains about 12% of the world availability of water resources, is a privileged country in view of the possibility of using these resources in different sectors, of which the agricultural sector, as a broad concept that involves agriculture, husbandry, and f

The national and international demand for ethanol and the increasing concerns with world climatic changes is generating the expectation of an increase in the use of biofuels and consequently an increase in the area planted with sugarcane in Brazil. Brazil is the largest producer and exporter of sugarcane products in the world, and the state of São Paulo has been responsible for nearly half of the national production in the latest years. Among the state's regions, the northeastern portion, whi

A geomorphological mapping of the Restinga de Jurubatiba National Park, in the State of Rio de Janeiro, was proposed in this project, to assist in environmental planning, using geotechnologies and geographic information systems. The delimitation of preservation areas such as the Restinga de Jurubatiba National Park aims to maintain the environmental balance of these environments, a necessary measure due to the expansion of urban areas that suppress natural areas. The paper presented a tempora

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

Pasture as an exclusive feeding source accounts for almost 90% of the beef consumed in Brazil and for most of the nearly 35 billion liters of milk produced annually in the country. It is estimated today that, in Brazil, grasses of the genus Brachiaria are cultivated in approximately 84 million hectares. In Brazil, the most cultivated species of Brachiaria are B. decumbens, B. brizantha, B. humidicola and B. ruziziensis. With the increasing agricult ...

Pastures assume a prominent position in the Brazilian agricultural scenario, covering about three quarters of the cultivated area nationwide. In addition to the physical aspect, pastures are the main feeding source for the Brazilian herd. Pastures account for almost 90% of the beef consumed in Brazil and for most of the 21 billion liters of milk produced annually in the country. It is estimated today that in Brazil grasses of the genus Brachiaria are cultivated in approximately 84 millio

Pastures assume a prominent position in the Brazilian agricultural scenario. The area occupied by forage plants accounts for three quarters of the national agricultural area. Pasture, as an exclusive food source, is the basis for nearly 90% of the beef consumed in Brazil and most of the milk produced in the country. It is estimated that, in Brazil, the grasses of the Brachiaria genus are cultivated in approximately 84 million hectares. Despite the nationwide importance of this grass for

Brazil leads the research on reproduction of forage plants, but faces as a challenge the low diversity of pastures, mainly formed by apomictic plants. Apomixia - asexual reproduction by seeds - is an area of biotechnology with great potential to optimize the genetic improvement of these species, as it develops genetic materials and procedures for plant cloning by the direct use of seeds. This project proposes the determination of strategies to regulate the genes associated with the mode of repro
