Leena A. Leskinen 《Small-Scale Forestry》2006,5(2):231-247
This paper examines the process of adaptation of the regional forestry administration in Finland to cross-scale socio-ecological
changes in national policies and in the forest ecosystem. Self-organisation and knowledge building are the key elements employed
in this case study conducted in the Southern Ostrobothnia Forestry Centre to analyse how the knowledge claims and networks
are created in order to implement wood energy development projects. The case study method and the theory of adaptive co-management
are found to be useful in explaining and understanding policy implementation and outcomes at the regional and local levels.
A wood energy project met the forest, climate change and rural development policy targets by facilitating the establishment
of a small heating business producing renewable energy from young forest thinnings. The practical outputs at the local level
were energy generation from a renewable source; an increase in the area of young forest management; and increased rural entrepreneurship
and employment. The unintentional output was that a new wood market arose. As a result of the case study, a two-level network
has been introduced as an adaptive policy implementation practice. 相似文献

U.S. forests, including family-owned forests, are a potential source of biomass for renewable energy. Family forest owners constitute a significant portion of the overall forestland in the U.S., yet little is known about family forest owners' preferences for supplying wood-based biomass. The goal of this study is to understand how Massachusetts family forest owners feel about harvesting residual woody biomass from their property. The study estimates the probability that Massachusetts landowners will harvest biomass as part of a timber harvest using data from a survey of 932 Massachusetts family forest owners. Logistic regression results suggest that the likelihood of harvesting for biomass is quite low, and that the supply of participation in biomass harvesting is inelastic with respect to price. These low probabilities may be due to the method used to account for preference uncertainty, as well as the unique nature of Massachusetts forests, forest markets, and landowner attitudes in comparison to other states (e.g., Minnesota). The study suggests that it would be more effective to target renewable energy policy toward different regions and/or markets rather than develop a uniform national policy. 相似文献

The review gives an overview of the increased utilization of forest biomass for energy. The emphasis is on Nordic countries, especially on Sweden and Finland with large biomass potentials and a high share of renewable energy in gross final energy consumption. The utilization and potential of forest chip sources such as logging residues, small-size tree stems and stumps that are normally not harvested in conventional harvesting are described. Environmental potential and impacts that may reduce the utilization of forest biomass are discussed based on recent publications. Finally, the review summarizes the future developments based on their relationship to policies, certifications and guidelines and forest owners' decisions. 相似文献

燃料能源林树种选育及培育技术研究进展 总被引:4,自引:0,他引:4
能源林作为生产并提供生物质能源的一种重要方式, 以其可再生、生物量大、环境友好及适应地域广而倍受国际社会关注。文中依据其主要用途将能源林分为燃油能源林、生物发电能源林与薪炭能源林等3类。燃油能源林树种包括续随子、霍霍巴、油楠等, 生物发电能源林树种包括柳树、桉树、杨树等, 薪炭能源林树种相对较多。生物发电能源林与薪炭能源林可统称为燃料能源林。目前, 国外十分重视燃料能源林树种选育及高产培育技术研究和实践。不同树种、无性系、种源的燃料能源林生物产量差异很大, 瑞典选育出蒿柳和毛枝柳等, 南魁北克选育出了柳树无性系SX64与SX61。造林密度与收获周期紧密相关, 巴西的澳洲金合欢树3年收获时密度以10000株/hm2生物量最大; 欧洲2年收获与3年收获的柳树能源林适宜密度为15000株/hm2。另外, 文中对能源林类型、燃料能源林树种选育、立地条件、造林整地、造林密度、收获周期、抚育管理等技术进行了介绍, 希望对能源林的栽培提供依据。 相似文献
