The Sustainable Forestry and African American Land Retention Program is a comprehensive effort to address the long-standing problem of underparticipation of African Americans in forest management. We conducted rapid appraisal baseline research for pilot projects in this program in three Southern states using a carefully selected purposive sample to enhance our understanding of minority landowne...

Introduction In normal times Great Britain imports all but 4 per cent. of the timber needed for her industrial requirements, chiefly from Canada, Scandinavia and the Baltic States, and forestry work in this country is carried on by the Forestry Commission and private owners, who do research and reafforestation, and clean up woodland areas. War with Germany, however, resulted in a rapid and cons...

The United States Climate Change Initiative includes improvements to the U.S. Department of Energy's Voluntary Greenhouse Gas Reporting Program. The program includes specific accounting rules and guidelines for reporting and registering forestry activities that reduce atmospheric CO2 by increasing carbon sequestration or reducing emissions. In the forestry sector, there is potential for the eco...

Carbon nanotubes (CNTs) have been readily functionalized by microwave activation using two different reactions affording functional derivatives characterized by two orthogonally protected amino groups. The doubly functionalized CNTs can serve as multipurpose, versatile synthons in materials science and biological applications.

Forestry is an effective strategy for climate change mitigation. However, forestry activities not only sequester carbon but also release CO2. It is therefore important to formulate carbon subsidy and carbon taxation policies on the basis of the price of carbon. In this study, a forestry-based Computable General Equilibrium (CGE) model was built by using input-output data of China in 2014 to con...

State-owned forestry enterprises are important elements of the forestry economy in China. The operational efficiency of such enterprises depends on technological progress and other input factors. Total factor productivity (TFP) is an important means to evaluate the efficiency of technical elements. The growth of production efficiency can be classified into efficiency variation and technical var...

Industrial forestry typically leads to a simplified forest structure and altered species composition. Retention of trees at harvest was introduced about 25 years ago to mitigate negative impacts on biodiversity, mainly from clearcutting, and is now widely practiced in boreal and temperate regions. Despite numerous studies on response of flora and fauna to retention, no comprehensive review has ...
