ABSTRACT Housing deficit is a problem that affects low-income populations in Brazil, with over 6 million families affected nationwide and approximately 631 thousand in the North region of the country. Ordinance no. 318/2014 of the Brazilian Ministry of Cities authorized the construction of popular housing using timber as raw material in that region. The objective of this study was to establish the unit cost of a wooden dwelling, referenced in the project Popular Wooden Housing (PWH) developed by the Laboratory of Forest Products and the University of Brasília (UNB) for the National Rural Housing Program (NRHP). The Basic Unit Cost (BUC/m2 ) methodology was used, with collection of prices in Rio Branco, capital of the state of Acre, for composition of the Final Unit Cost (FCU/m2) of a wood construction. Mean cost of R$ 934.52/m2 was observed from September 2015 to April 2016. Feasibility of wood construction was demonstrated by a final cost per m2 28.06% lower than that of a conventional masonry house.

RESUMO Este trabalho testa a importância relativa de um grupo de temas pré-selecionados, contribuindo para a construção de um Sistema de Informações Florestais para o Brasil – SIFLOR-BR. A metodologia empregada se pauta em um conjunto de 12 módulos temáticos e 58 subtemas para serem avaliados por um grupo de pessoas (método de juízes holístico). As informações referem: 1) Cobertura florestal; 2) Florestas de produção; 3) Propriedade das terras florestais; 4) Indústria de base florestal; 5) Mercado de produtos florestais; 6) Tecnologia de produtos; 7) Biodiversidade florestal; 8) Mudanças florestais e climáticas; 9) Economia e estatística florestal; 10) Legislação florestal; 11) Certificação florestal; 12) Ensino e pesquisa florestal. Conclui-se que as principais informações que deve conter o SIFLOR concentram-se nos temas Produção e Economia florestal.

ABSTRACT Determinants for a forest information system. This paper tests the relative importance of a group of pre-selected themes for the construction of a Forestry Information System for Brazil – BR-SIFLOR. The methodology that was used lies on a set of 12 thematic modules and 58 sub-themes in order to be evaluated by a group of people (holistic judging method). The information relates to: 1) Forest cover; 2) Production Forests; 3) Ownership of Forest Lands; 4) Forest-based Industry; 5) Forest Products Market; 6) Technology Products; 7) Forest Biological Diversity; 8) Climate Change and Forest; 9) Forest Economics and Statistics; 10) Forest Law; 11) Forest Certification; 12) Forestry Teaching and Research. We conclude that the key information to be included in the SIFLOR focus on themes of Forest Economy and Production.
