Carbon sequestration activities in the forest: strategies and challenges.

摘要

Climate change, land use change and the world's forests arc inextricably linked. Forests cover more than 4 billion hectares of the earth's land surface area and contain huge reservoirs of carbon in their biomass and soils. Understanding the role of forests in carbon cycles and predicting whether they will be carbon sinks or sources in the future are important in the ongoing international dialogue on climate change. Long-term storage of carbon on land provides a solution, by which humans can modify the dynamics of the carbon cycle. Methods include reducing land disturbance, reforestation, afforestation, altered forest management practices, altered land-use patterns and consumption, and fossil-fuel substitution. Man-made emissions of the greenhouse gas. carbon dioxide, into the earth's atmosphere continue to escalate. There is a need to improve forest management and its economic implications with respect to improving carbon sequestration.
