The global trend of gradually replacing fossil energy sources with fuels from biomass benefts Brazil enormously, expanding the need to increase the area of forest plantations and promoting the strengthening of partnerships with specifc segments of the private sector for the development of products that are appropriate to clonal forestry. Currently, there is a lack of genetic material that is adapted to face the natural edaphoclimatic limitations in certain regions under the concept of forest plantations that serve multiple uses, especially in a scenario aggravated by climate change. The objective of the project was to expand opportunities for feld experimentation, improvement in multi-environments and product validation, contributing so that the territorial expansion of eucalyptus plantations, even under possible efects of global climate change, may take place in the future and be less subject to the risk of compromised production. The project brought together actions from the Eucalyptus Genetic Improvement Program (PMGE) to launch products prepared for planting in rural properties in the country, with the raw material produced being applied for multiple uses, with emphasis on energy and wood solids (Figure 1). Emphasis was placed on obtaining wood for sawn products and energy, considering not only traditional production systems, but also silvopastoral and agroforestry systems. Using practical processes to produce hybrid experimental seeds by open pollination, the improvement of techniques for the early selection of technological characteristics of wood, the application of controlled pollination in a pot crossing orchard and genetic prospection and transformation studies make up a set of innovative actions presented in the technical content of this project. The project aimed to meet the demands of man-made forest plantations and demands for the production of material from forest origin, mainly on small and medium sized rural properties, established in diferent and diverse Brazilian regions. • In order to understand the thermal, water and biotic stresses that afect the productivity of wood from notably clonal genotypes, the specifc objective of the project was to identify genotypes that are tolerant to the environmental stresses mentioned; • Predominantly conventional forest production systems were used, through experimental/ technological reference units established in seminal and clonal form, and developed actions in the Atlantic Forest, Cerrado, Caatinga and Amazon biomes; • As a methodology, the experimental feld modules were systematically monitored through assessments on survival, wood production and the direct and indirect efects on trees caused by diferent stresses, evaluating their nature and intensity; • The project seeks to contribute to climate change adaptation through identifying and using genotypes with adaptive responses consistent with desired silvicultural performances, that have greater capacity for survival under observed conditions, refected by the productivity of wood; • The target audience, in general, was represented by forest nurseries, rural farmers and wood consumers; • The budget allocated to R&D was provided by Embrapa from direct and indirect resources contributed through partnerships with seedling producers, forest-based companies, cooperatives and mining companies.
