Amazonian dark earths are highly rich soils that resist degradation. They have an extraordinarycapacity to sequester carbon and are known to augment agricultural production. Because ofthese characteristics, these dark earths have been proposed as a model for sustainableagriculture. But most attempts to recreate them have been unsuccessful, with little research ordata on the role of soil biota in the productivity and resilience of this ecosystem. An initialassay in a greenhouse simulated dark ear

The project aimed to quantify carbon stocks and assess the impact of human activity on changes in carbon stocks in the Amazon Forest. In that region, in response to the potential climatic effects of deforestation, policy makers have paved the way for policy changes that drive emission reductions by reducing deforestation and forest degradation and the improvement of forest carbon stocks. The project was part of the “Sustainable Landscapes” program of technical cooperation from USAID and the U.S.

The GUIAMAFLOR project includes French (Guyana and Montpellier) and Brazilian (Manaus and Macapá) research partners. The fieldwork is located in four sustainable systems in three Amazonian regions (French Guyana, Amapá and Amazonas) aiming to understand how environmental factors influence the forest dynamic after logging in multiple intensity levels. With the project’s results it will be possible to make a synthesis of the knowledge about forests’ functioning after logging to improve forest m

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

The project aims to estimate carbon balance in different grain production system scenarios in the major Brazilian biomes, ranking those that reduce the consequences of climate change, via computational simulators. The information generated in this project will be used in the project "Classification and spatialization of grain production systems with the use of remote sensing", aiming to produce regional estimates of the carbon balance and GHG emissions for Brazil's entire grain production area. ...

Low-carbon agriculture, a program introduced by the Ministry of Agriculture, Livestock and Food Supply in mid-2010, aims to combine the sustainable production of food, fibers and energy with the reduction of greenhouse gas emissions and the conservation of natural resources. To this end, the Brazilian government encourages the use of the following techniques: no-till farming, biological nitrogen fixation, integrated crop-livestock-forest systems, planting of commercial forests, recovery of de

Agricultural systems basically depend on ecological processes and services provided by ecosystems. These ecological processes and services, called ecosystem services or environmental services, relate to the conditions and processes through which ecosystems sustain human life by supplying provisions (food, timber, fiber and fuel production), regulation (of water, of climate, protection against droughts, flooding, storms, spread of diseases and soil degradation, waste purification), support (hydro

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
