In Brazil's Pará State, 60% of potentially managed forests are on community lands, while commercial timber concessions cannot cover more than half of current demand. With a few exceptions, traditional communities and smallholder families have neither the technical knowhow nor the economic capacity to conduct commercial logging operations: these are undertaken through agreements with a company under varying arrangements. Given this context, contracts between communities and companies are highly variable and always lead to the company exercising complete control over all operations, from management plans through to production. Public policies and land tenure regulations are now seeking to improve local community capacities for protecting their interests in partnerships of this kind. This study analyses how the financial business framework compares with smallholder organisation in the execution of these contracts, and addresses the key factors that could ensure better control: pre-logging inventories, diversification of production to include non-timber forest products as well as timber, marketing, monitoring and inspections of logging operations. Some possibilities of public policies are put forward to help disseminate the smallholder development under different land tenure regimes, such as conservation units in production forests or agricultural production boundaries. The article discusses ways in which a public service for technical and financial assistance to farmers and communities could act and become established. The potential for integrating forest management into small-scale farming systems is discussed in the light of the current debate on reform of the forest code. Source

This work aims to determine an optimal storage time of forest biomass for use in energy production, through analysis of variations in physical and chemical properties of with bark timber over the storage period. The study was conducted in the municipality of Lages, SC, over a span of 18 months. The experiment used with bark logs of Pinus taeda and Eucalyptus dunnii, with varying diameters, and slabs of Pinus spp., stored in piles. The material was sampled freshly harvested (control), after two, after four and after six months of storage. Four lots were used, harvested and stored at the spring, summer, autumn and winter seasons. Properties being assessed included moisture content (wet basis), gross calorific value, net calorific value and ash content. Results demonstrated that storage time influenced moisture content and net calorific value, yet it had no influence on gross calorific value and ash content. Optimal storage time ranged from two to four months, depending on the species, form of biomass and storage season. The best behavior regarding quality after storage was from Pinus slabs, followed by Eucalyptus logs and Pinus logs, the latter showing the worst behavior. Source

This research aimed to study the increase in diameter, basal area, volume, the entry, and the mortality of an open/seasonal ombrophilous forest in the city of Marcelândia. Data were collected in 69 permanent plots established in 2001 and remeasured in 2003 and 2007. The number of individuals and the increases in diameter, basal area, and volume for the period 2001 to 2007 were evaluated. The entry was determined by the trees that have reached or exceeded a diameter of 17 cm. Mortality was calculated as the sum of all found dead trees in each measurement with a diameter equal or more than 17 cm. In the considered period of six years, the results to the increase in diameter, basal area, and volume were respectively, 0.34 cm, 0.22 m2.ha-1, and 2.11 m3.ha-1. The average values for the mortality rates and entry respectively were 0.78% and 0.30%. Source

This research develops a strategic analysis of supported timber production in the Brazilian Amazonia, with focus in the sustainable forest management plans in the region. The methodology is based on the use of SWOT Analysis to determine the strengths and weaknesses, opportunities and threats of forest in the Amazon. Therefore, we interviewed 40 professionals who work with forest management. As result, we identified as the main positive point the management as way of maintenance of the forest covering. On the other hand, the main weake point is the lack of control of illegal wooden extraction. The main opportunity is the great amount of available areas for the forest management. Finally, the main threat is the unfair competition with the illegal wood. Source

Brazil has a predominantly renewable origin electricity generation matrix, with hydro generation accounting for about 69% of the supply. This paper promotes hydropower projects in Brazil environmental licensing procedure critical assessment, with the aim of identifying and assessing possible solutions to enhance the process, especially through Strategic Environmental Assessment (SEA) application to hydroelectric generation expansion planning processes. It was concluded that impact assessment has led to significant environmental improvements, as it is capable of preventing, controlling and compensating significant - and very often irreversible - environmental impacts, especially through projects optimization and environmental programs that were not initially foreseen in the EIA inclusion. However, as has been expounded throughout this study, there are still several gaps and limitations in the current process, both in power generation expansion planning aspect and project environmental impact assessment aspect. SEA application in the planning phase could contribute to facilitate and simplify hydroelectric plants licensing. Many currently compulsory stages that are carried out after the request for a prior license, such as the consultation made to involved entities and the area environmental diagnosis could already be commenced in the planning phase. © 2015 Elsevier Ltd.
