Trends in management of the global forests and impacts on carbon stocks
()
Abstract:
Global forests are increasingly affected by changes in land use, decentralization, changes in management objectives and degradation. This paper describes trends in global forest area through management intensity and outlines global carbon stock changes associated with forest management. Discussed the different interpretations of management and highlighted some important accounting and analysis issues. The global forest area has fallen by 3 per cent since 1990. As of 2010, the area of planted forests has increased worldwide and now accounts for nearly 7 per cent of the global forest area. The habitat fragmentation and degradation caused by human factors have resulted in a 34 per cent reduction in the virgin forest area of all forest land, especially in South America and Africa. At the same time, the area of natural regeneration forest has also declined. As a result of the increase in management intensity, non-operating forest area (usually defined as a lack of human management plan or protected land) has declined significantly since 1990, only 21% of the global forest, and for soil and water conservation, biodiversity protection and provision of ecosystem services such as non-timber forest product land area increased significantly. Globally, timber production has been relatively stable since 1990, but the area of non-timber forest products is increasing, indicating that the area of forest logging is smaller than the total forest area. Based on trends in the management of forests and regional research, it is clear that historical and current forest management is a very important determinant of current carbon stocks. At present, the completed forest has offset about 30% of the global CO2 emissions from fossil fuels, while reducing deforestation may reduce the total terrestrial carbon footprint from about 4.0 to 6.2 tonnes per year. However, our findings suggest that diversification of the use of forest land may have a significant impact on maintaining or enhancing the current terrestrial carbon sinks. In the future, indirect human impacts such as increased atmospheric carbon dioxide and climate change, as well as the direct impact of land management and the growing demand for wood biofuels, will become increasingly influential in land management strategies and the role of forests in the global carbon cycle.
