The intense world demand for food together with environmental issues related to the sustainable use of natural resources draw a picture of search for the maximum efficiency in agricultural productivity, which involves greater efficiency in monitoring crop areas. Analytical tools capable of encompassing sample variation and territorial reach demand high costs for their operation and for the replication of results. Remote sensing has proved a very efficient tool for mapping/monitoring agricultu ...Status: Completed Start date: Thu Sep 01 00:00:00 GMT-03:00 2011 |
| Along with current demand for palm oil ("dendê" oil) by the industries of food, pharmaceuticals, chemicals, and bio-fuel, it is important to encourage the advance of researches regarding handling techniques that allow longevity, increase in cultivated areas and productivity of the Palm Oil Tree ( Elaeis guineensis Jacq.).

Forest systems are part of an important land-use strategy aimed at the maintenance of biodiversity, at the commercialization of wood products and other products, at quality of life and at environmental services such as carbon fixation. The greenhouse gas emission flows and the carbon stocked in the forests are indispensable information, and their estimation may support public policies on development and sustainability. Project GeoSaltus focuses on the use of geotechnologies for the developmen ...Status: Completed Start date: Fri Jun 01 00:00:00 GMT-03:00 2012 |
| This project arose from the need to generate and consolidate geospatial databases, implementing an infrastructure in order to organize and make this data available to improve Embrapa's RD&I capacity. As well as to allow sharing of the data collection to other government agencies and to society, and also the establishment of a multiuser reference center for obtaining spectroradiometric measurements of targets of interest to tropical agriculture. The implementation of Embrapa's Spatial Data Infras ... Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| 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 Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| The project aimed to assess the forms of land use and forest degradation processes in the Amazon, by reconstructing the history of degradation in three municipalities (Paragominas and Santarém – PA and Feliz Natal – MT). In these municipalities, the socio-environmental aspects of forest degradation, related to changes in land use and coverage, were analyzed (pasture, agriculture, secondary use, logging, etc.), along with data produced by research partner networks and the vast literature already ...

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 ...Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2008 |
| 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 Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| 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 Status: Completed Start date: Wed Sep 01 00:00:00 GMT-03:00 2010 |
