Forest loss and degradation remains a leading environmental problem. The long history of sustainable forest management has often failed to meet expectations—constrained by funding, governance, capacity and competing interests. Initiatives from the climate change policy arena are opening new ways for a broader mainstreaming of forest management, specially through foreign aid mechanisms towards R...

Mr Gray dealt very largely with the finances of growing a crop of trees but there are a number of other factors which have considerable influence on forest policy and economic planning and I propose to highlight a few of these The details are relevant to Northern Ireland and were originally prepared in somewhat greater detail for a symposium of forest officers Opinions and forecasts are not off...

Carbon leakage can be a problem when seeking to reduce carbon emissions through forest policy. International market leakage is mainly caused by supply and demand imbalances in the timber market. This paper selects China, which is implementing forestry policy changes, as the research object. We begin by offering a brief analysis of China’s forestry policy changes, such as the logging quota and S...

Understanding forest changes and its trajectory is important to develop policy options and future scenarios for climate analysis. This research is conducted to gain insights on secondary forests change using Mississippi, USA, as a case study. We investigate the spatial patterns and temporal dynamics of secondary forests at high resolution and examine the forces driving their changes. An extensi...

Forest management worldwide is increasingly focused on values such as biodiversity conservation, carbon, water and recreation as well as timber production. Ownership and governance arrangements are also changing, with an increase in private ownership of forest resources that is focused on timber production and devolution of management and control to the community level. Forest management is par...

Forest biomass is a significant indicator for substance accumulation and forest succession, and a spatiotemporal biomass map would provide valuable information for forest management and scientific planning. In this study, Landsat imagery and field data cooperated with a random forest regression approach were used to estimate spatiotemporal Above Ground Biomass (AGB) in Fuyang County, Zhejiang P...

The 21”’ century continues a trend of rapid growth in both international trade of forest products and a concern for forests. These two trends are connected. Forces causing trade growth are linked to the loss of native forest resources in some countries and the accumulation of nonnative forest resources in other countries. Factors increasing trade include relaxation of trade barriers, income gro...

Efforts to increase wood mobilization have highlighted the need to appraise drivers of short-run timber supply. The current study aims to shed further light on harvesting decisions of private forest owners, by investigating optimal harvesting under uncertainty, when timber revenues are invested on financial markets and uncertainty is mitigated by news releases. By distinguishing between aggrega...

Codes of forest practice are sets of regulations or guidelines developed by governments or other organisations to assist forest managers select practices to be followed when carrying out forest management and utilisation operations. These practices, when correctly applied, should meet standards for sustainable forest management (Dykstra 1996; Dykstra and Heinrich 1996). A code of practice is al...
