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

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

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

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

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

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

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products

Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met

Some results of practical interest to soil management can be extracted from the soil's water retention curve. The recent validation of the Arya and Paris model for Brazilian soils created excellent opportunities to expand the functionality of the soil granulometric analyzer which is used to obtain in detail the entire particle distribution curve. Since the granulometric analysis takes only 20 minutes, at the same time, through the developed computing implementation, the following results can als
