1. WOOD RESOURCE BALANCE FOR PLANTATION FORESTS IN BRAZIL: RESOURCES, CONSUMPTION AND CASCADING USE
ABSTRACT A resource balance comprises a method to monitor sources and uses of a given material. The wood resource balance analyses origins of wood resources used in the production of semi finished forest products. At the same time, the resource balance helps tracking wood processing residues and its further uses. A primary survey with 113 companies was condu

2. MULTILEVEL NONLINEAR MIXED-EFFECTS MODEL AND MACHINE LEARNING FOR PREDICTING THE VOLUME OF Eucalyptus SPP. TREES
ABSTRACT Volumetric equations is one of the main tools for quantifying forest stand production, and is the basis for sustainable management of forest plantations. This study aimed to assess the quality of the volumetric estimation of Eucalyptus spp. trees using a mixed-effects model, artificial neural network (ANN) and support-vector machine (SVM). The datab

5. A desvalorização cambial e a exportação de produtos florestais madeireiros
Resumo O objetivo deste artigo é analisar o comportamento das exportações de produtos madeireiros do setor florestal após a desvalorização cambial, a partir de 2012. O método de avaliação de impacto foi o de diferença em diferenças (DD). Os resultados apontam que, apesar de as exportações representarem, em média, volume menor que a comercializa

6. Painéis de partículas elaborados do mesocarpo do dendê como alternativa ao MDF utilizado na construção civil
RESUMO A escassez dos recursos florestais integrada à necessidade de aquisição de produtos mais ecológicos demanda o uso de outros tipos de biomassa, além da madeira no setor construtivo. Diante disso, o mesocarpo do dendê - resíduo oriundo da agroindústria e com grande potencial de utilização para desenvolvimento de novos materiais - surge como al

7. Comparing the Performance of Ground Filtering Algorithms for Terrain Modeling in a Forest Environment Using Airborne LiDAR Data
ABSTRACT The aim of this study was to evaluate the performance of four ground filtering algorithms to generate digital terrain models (DTMs) from airborne light detection and ranging (LiDAR) data. The study area is a forest environment located in Washington state, USA with distinct classes of land use and land cover (e.g., shrubland, grassland, bare soil, an

10. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this
