A general methodology is proposed to evaluate forestry programs which are aimed at increasing timber supply from non-industrial private forest lands. A financial analysis of the forestry activities included in the program or a questionnaire submitted to the landowners should serve to establish what would have been done in the absence of the program. An economic analysis aggregating the marginal benefits and costs for each program participant can be related in different benefit—cost ratios.The methodology is applied to the evaluation of the Forestry Incentives Program (FIP) in Massachusetts. The study shows that the efficiency benefit—cost ratio is > 1 at 4% and 6.625% and that the landowner's management decisions are crucial to the performance of the program.  相似文献

This paper reports findings of surveys into small-scale sawmilling and timber processing in Phu Tho Province and the Tam Dao National Park buffer zone in northern Vietnam. The objective of these surveys was to examine the extent to which small sawmills and timber processors utilise farm-grown timber, so as to explore the prospects for expansion of farm-grown timber markets. The operational scope, supply chain and value chain of the industry are reported. Resource availability and current and future perspectives are discussed. Timber prices were found to vary greatly between species and study areas. Species most in demand by enterprises are Artocarpus heterophyllus, Melia azedarach, Manglietia conifera, Acacia spp., Chukrasia tabularis and Erythrophloeum fordii. Small-scale sawmilling and timber processing activities fit well with rural communities in Vietnam and have potential for further development if current constraints can be overcome. Further tree planting is needed to meet the presently unsatisfied timber demand and to create income and employment. Information from sawmillers and timber processors suggests the types of species that farmers should be considering for their plantings.  相似文献

Data collection and maintenance of databases concerning smallholder forestry presents special problems in developing countries. This paper examines forestry data collection experiences in a series of research projects in Leyte, Philippines, supported by the Australian Centre for International Agricultural Research, and the prospects for developing forestry accounting networks. A variety of financial data have been collected in relation to seedling production, plantation performance and timber marketing. Seedling production cost and revenue data have been obtained through snapshot surveys conducted in 2002 and 2008, and repeated attempts have been made to estimate financial returns from growing the most popular tree species. Diverse sources have been identified for timber market information. On the supply side, these include government records of registered plantations, obtaining inventory data from barangay (community) leaders, and reporting information about timber available for harvest on community notice boards. On the demand side, official records of registered timber merchants have been accessed, a detailed survey of timber processors has been conducted, and estimates are being made of apparent per capita timber consumption by district. Experiences in the Philippines reinforce that the potential for forestry accounting networks is limited by the resource-constrained situations of developing countries, placing greater reliance on one-off surveys. Use of pre-existing local networks and institutional structures offers potential for routine collection of forestry data, such as through barangay (village) leaders in the Philippines.  相似文献

The large and unutilised native forest timber resource on traditional Wik land on Cape York Peninsula, Australia, could be managed for timber production to contribute to Wik socio-economic objectives. Wik elders have a set of forestry objectives and envisage that these will be best achieved by a timber industry selling unprocessed logs and woodchips. On the other hand, Balkanu Cape York Development Corporation, a government-funded indigenous community development organisation, anticipate that an industry utilising high-technology equipment and producing dried and dressed finished products including strip-flooring will best satisfy Wik forestry objectives. The Wilderness Society envisages small-scale ‘community development’ activities such as protable sawmilling and niche market furniture manufacture as being appropriate types of forestry activities on Wik land. Goal programming analysis of forest use opportunities indicates that Wik forestry objectives are unlikely to be best satisfied by adopting the timber utilisation options espoused by any one of the stakeholder groups.  相似文献

The Community Rainforest Reforestation Program (CRRP) in north Queensland, Australia, was a multi-faceted experiment in facilitating farm forestry. It was motivated in part by the World Heritage listing of the Wet Tropics of Queensland rainforests, which removed a large resource from the timber industry. Survey results indicate that some landholders have applied high-quality silvicultural management to their stands with a view to timber production, while others have been more interested in wildlife habitat and other non-wood benefits. Although not necessarily a success in terms of its stated goals, the program can be credited with a number of achievements. It yielded valuable experience in growing native tree species, job training for young unemployed people, and collaboration between Federal, State and local government in forest industry development. The program generated positive environmental outcomes and lessons for future timber and environmental planting programs on private lands. While the area planted and quantity of timber produced will fall far short of initial expectations, and some limitations arose with the job training activities, it nevertheless appears to have been a worthwhile project.  相似文献

1973~2003年中国林业生态足迹的研究   总被引:2,自引:0,他引:2  
生态足迹是评价可持续发展能力重要指标之一,该方法自提出以来得到广泛关注和迅速应用。首先,本文分析了中国1973-2003年木材生产、进口和出口情况,结果表明,中国在1973-1995年期间木材生产呈明显波动变化趋势,1995年后呈现连续下降趋势;木材进口在1995年后特别是天然林保护工程实施后呈增长趋势,而木材出口在1995年后呈逐年下降趋势。然后,采用改进的生态足迹方法(即森林可持续产量法与森林实际生产法)计算了中国1973-2003年间的林业生态足迹(包括进口与出口林业生态足迹),分析表明,1978-1988年期间,实际生产法计算林地真实面积小于可持续产量法计算结果,而1989-2003年正相反,上述两种方法的计算结果均大于用全球产量计算的林业生态足迹。说明中国在1978-1988年间森林资源消耗量大于生长量,林业发展是不可持续的;1989年后森林资源消耗出现长大于消的局面,林业朝着可持续的方向发展,但同林业发达国家相比仍有较大的差距。最后,讨论了林业生态足迹与国家重要政策(包括外贸、经济与森林保护政策)的关系,并提出了减少林业生态足迹与增强林业可持续发展能力的几点建议。图3表1参31。  相似文献

Large forest estates actively participate in the marketing of timber in France. However, the marketing of wood from private and public large forest estates (over 25 ha) could be improved by better managing price risk in multiannual supply contracts of the timber industry: creation of compensation funds for forest owners or calls to financial markets linked to processed timber products for industrialists. But, the development of supply contracts does not mean that private or public auction procedures should be abandoned. Similarly, by supplementing “forest area development schemes”, it would be possible to increase the mobilisation of timber produced on small (1 to 10 ha) and medium (10 to 25 ha) forest estates: more forestry cooperatives or local forest agencies and a new timber pre-sale mode adapted to small forest estates are necessary (sales subject to the buyer's choice of purchasing standing timber or cut wood delivered to a depot by the seller).  相似文献

About 80% of annual wood fiber consumption in Japan is imported. Even though most of the land surface is covered by forests in Japan, the domestic forestry and forest industry are threatened by such imports flooding the local market. Fragmented land ownership, steep terrain, rapid growth of weeds, and high labor costs have all contributed to the decline of domestic forestry. Further, the purchasing power of the Japanese Yen has become very strong in recent years, and the decreasing prices of imported timber have depressed the prices of domestic timber, eroding profitability and discouraging small-scale forestry. In spite of these difficult circumstances, there are several interesting new developments in Japanese forestry. One is the revision of the Basic Forestry Law of 1964, through which the Japanese government is steering forest policy from timber production towards environmental services. Because of this change, new ways to assist rural forestry activities will become available in the near future. Another change is the certification movement, where recent examples of Japanese companies acquiring ISO 14001 and Forest Stewardship Council (FSC) forest certifications provide hope to depressed domestic forestry activities. In particular, FSC group certification is useful in motivating small-scale forest owners to implement and maintain sustainable forestry practices. This paper is based on the presentation at IUFRO Group 3.08.00 Symposium at Joensuu, Finland 2001. The original article, ‘The economic situation of small-scale forestry in Japan’, is in Niskanen and Vayrynen (2001).  相似文献

This article investigates the regional economic impact sensitivity to the current mountain pine beetle infestation in five study areas of British Columbia, Canada, using a computable general equilibrium framework. Baseline general equilibrium economic databases are constructed for each region using a hybrid data collection approach involving primary and secondary sources. A computable general equilibrium model is constructed for each region and used to simulate the sensitivity of a suite of economic indicators to changes in forestry sector exports resulting from the impacts of mountain pine beetle on the available timber supply. The computable general equilibrium models constructed for each region provides an indication of economic vulnerability to the infestation and can assist decision-makers with the identification of policy considerations and priority areas for mitigation planning in response to the anticipated fluctuations in timber supply.  相似文献
