The Amapá state has extensive forests and savannas, which are important carbon stocks being negatively affected due to agricultural, forestry and industrial activities. Thus the project aims to develop a methodology applicable to the entire State of Amapá, aiming to reach all types of existing vegetation, being the basis for estimates of forest biomass and the quantification of carbon stocks, in addition to enabling the monitoring of changes caused on biomass due to the economic activities de

The goal is to assess the economic and ecological effectiveness of different models of forest restoration of degraded areas through the induction of secondary ecological succession, by natural regeneration, planting of seedlings, and the direct sowing of native and exotic tree species to compose the Legal Reserve.

In the last century, the wide use of Guzerá breed in crossbreeding led to the expressive reduction of their effective population size, to worrying numbers. Due to its adaptation to diverse environmental conditions, its potential for dual-purpose production (i.e. meat and milk), and its risk of extinction, in 1991, this breed was included by FAO (Food and Agriculture Organization of the United Nations) in the list of genetic resources to be preserved. In view of this, and due to the demand for br ...

This project proposes the morphological and physico-chemical analysis of Brazil nut trees, in addition to the study of their diversity, intrapopulation spatial genetic structure, reproductive system, and patterns of seed and pollen dispersal in natural populations located in the Brazilian states of Mato Grosso and Acre. Furthermore, abiotic aspects such as weather variables and soil fertility and structure will be monitored, and there will be a survey on the constitution of the historical ethnob

Despite the growth in the production and productivity rates of dairy farming in Brazil, the globalization of the economy, the fluctuations in domestic and foreign food prices, the changing feeding habits of the population, with the growing interest in functional foods as well as foods from agroecological or organic production systems, coupled with the strong demand for genetically improved and adapted animals, are relevant factors that have challenged research and development agencies in proposi

The ‘cipó-titica’ vine (Heterops flexuosa) is a non-timber forest product of economical importance in Amapá. Its long and resistant aerial roots have historically been used for crafting furniture, utensils and handcrafts. The project will be situated in Nova Canaã settling, at Porto Grande municipality (Amapá) and aims to evaluate cipó-titica plants density in the forest in order to identify phorophytes (tree species that host the vine) and thus determine the rate of growth and emission of ne

Oriental Amazon Embrapa has an ample research history in various native essences of the amazonian ecosystem, including the big leaf mahogany ( Swietenia macrophylla King). However, the formation of a research network focused in studies regarding the interaction between the mahogany shoot borer ( Hypsipyla grandella Zeller), its natural enemies and its most important host remains a demand to be fulfilled. The damage caused by this insect consists of the destruction of the tree's ter ...

Project focused on the development of collaborative research on the ecology, management and technological processing of andiroba oil, strengthening the integration of related countries and the conservation of the Amazon rainforest in the region of the Guiana shield. Among the specificities of this study are the comparison of traditional andiroba oil extraction processes in the Brazilian Amazon and in Suriname; monitoring the production and physical-chemical quality of oil associated with best
