The adoption of agro-forest systems (SAFs) which are based in (agro) ecological practices has great potential for generating social, economic and environmental benefits, above all to family farmers. Thus, it was implanted, in the county of Tomé-Açu, Pará, SAFs composed by annual and perennial species, combined with Palm Oil Trees (Elaeis guineensis), in three family estates. In each one of them, the SAFs were installed after the area's preparation without the use of fires, based in the principle ...

Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc

The general objective of this project was to identify microbial strains that produce enzymes capable of degrading fibers or hydrolyzing secondary anti-nutritional compounds, aiming to identify microbial isolates (rumen bacteria or fungi) with fibrolytic capacity or tolerant to anti-nutritional factors, as well as to expeditiously isolate and characterize fibrolytic enzymes. It was also the objective of this project that the use of laboratory procedures would serve to train undergraduate and grad

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

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

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

The project “Technology transfer to consolidate low carbon emission agriculture in Tocantins” was carried out to consolidate an agriculture based in low carbon emission technologies, sharing the knowledge in conservation agriculture through capacity building of scientists, agronomists, extension workers and consultants, which were then capable to transfer low carbon technologies such as no-till system, degraded pastures recovery and integrated crop-livestock-forestry systems to farmers of all st
