Descrição

Doutoramento em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia The production flows in the sector of wood construction and furniture, paper and paper board and that of wood, paper and paper board wrapping and packaging sector are analyzed. The macroeconomic indicators associated with them are characterized, showing their importance in the Portuguese national economy. The characteristics of the corresponding enterprises and workforce, as well as the main domestic and international market trends for the different phases of the productive cycle are described. The recent evolution of wood production from maritime pine (Pinus pinaster Aiton) and eucalyptus (Eucalyptus globulus) is described and analyzed in a context that takes in account their potential to supply raw material for wood based industries. The effect of forest fire regimes and cuts on wood availability is modeled, using National Forest Inventories data and wildfire statistics. The models were used in predictions of future wood availability under various fire scenarios. Models for the supply and domestic consumption of sawn wood, wood panels, wood pulp, and paper and paper board, based on econometric equations, were developed.
