Forests are important for providing wood for products and energy and the demand for wood is expected to increase. Our aim was to estimate the potential supply of woody biomass for all uses from the forests in the European Union (EU), while considering multiple environmental, technical and social constraints.The potential woody biomass supply was estimated for the period 2010-2030 for stemwood, residues (branches and harvest losses), stumps and other biomass (woody biomass from early thinnings in young forests). We estimated the theoretical biomass potential from recent, detailed forest inventory data using the EFISCEN model. Constraints reducing the availability of woody biomass were defined and quantified for three mobilisation scenarios (high, medium, low). Finally, the theoretical potentials from EFISCEN were combined with the constraints to assess the realisable potential from EU forests.The realisable potential from stemwood, residues, stumps and other biomass was estimated at 744 million m3 yr−1 overbark in 2010 and could range from 623 to 895 million m3 yr−1 overbark in 2030, depending on the mobilisation scenario. These potentials represented 50-71% of the theoretical potential. Constraints thus significantly reduced the biomass potentials that could be mobilised. Soil productivity appeared to be an important environmental factor when considering the increased use of biomass from forests. Also the attitude of private forest owners towards increased use of forest biomass can have an important effect, although quantifying this is still rather difficult.The analysis showed that it is possible to increase the availability of forest biomass significantly beyond the current level of resource utilisation. Implementing these ambitious scenarios would imply quite drastic changes in forest resource management across Europe.  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

Norway has set ambitious targets for increasing bioenergy production. Forest residue extraction levels are currently very low, but residues have the potential to be an important component of the wood energy supply chain. A representative sample of Norwegian nonindustrial private forest owners having at least 8 ha (20 acres) of productive forest land was surveyed about their willingness to supply logging residues for wood energy production. About 59 % responded that they were willing to do so. Logistic regression analyses revealed that the following factors were positively associated with the likelihood of being willing to supply logging residues: total forest area, education level, living in a region with active timber markets and a history of forest production, and having positive perceptions of residue extraction and forestry’s role in mitigating climate change. Four variables were negatively associated with the likelihood to supply residues: living on property, being older than 65 years, having family or friends who are opposed to residue extraction, and having negative perceptions of residue extraction. The study provides insight regarding nonindustrial forest owners’ attitudes towards extraction of forest residues that may aid policy-makers designing effective means to meet national bioenergy production goals.  相似文献

In Montana, USA, there are substantial opportunities for mechanized thinning treatments on public forests to reduce the likelihood of severe and damaging wildfires and improve forest health. These treatments produce residues that can be used to generate renewable energy and displace fossil fuels. The choice modeling method is employed to examine the marginal willingness of Montanans' to pay (MWTP) for woody biomass energy produced from treatments in their public forests. The survey instrument elicited social preferences for important co-benefits and costs of woody biomass energy generation in Montana, namely the extent of healthy forests, the number of large wildfires, and local air quality. Positive and statistically significant MWTP is found for woody biomass energy generation, forest health and air quality. MWTP to avoid large wildfires is statistically insignificant. However, MWTP for woody biomass energy diminishes quickly, revealing that Montanans do not support public forestland management that produces more than double the current level of woody biomass harvested for energy generation. These findings can be used by policy makers and public land managers to estimate the social benefits of utilizing residues from public forest restoration or fuel treatment programs to generate energy.  相似文献

Among other factors, harvesting intensity in private forests depends on property, resource and forest owner characteristics. The research was conducted in Slovenia, a Central European country with very fragmented and small-scale forest property, a large number of owners and co-owners and a long tradition of sustainable forest management. In the nationwide study, data from the Land and Property Register and forest inventory database were used to build a logistic regression model to identify factors that influence harvesting intensity. The results of the model revealed that growing stock, share of conifers, share of forest area under regeneration, total size of forest property in owner- and co-ownership, parcel size and accessibility of the forest area to forest operations increase harvesting intensity. Slope, number and age of owners and co-owners, and skidding distance negatively influence harvesting intensity. The results can offer useful information for policy and decision makers for formulating policy as well as implementing the most suitable mix of policy instruments.  相似文献

Ownership is a multidimensional phenomenon that includes legal, social, and emotional aspects. In addition to legal aspects, the social and emotional aspects, “feelings of ownership,” potentially have behavioral effects. Nevertheless, these aspects are often overlooked in the research influencing the forest owners' behavior and thus their forest management decisions. This article examines how private forest owners with inherited forest holdings construct feelings of ownership toward their forests and how these constructions are reflected in their forest management decisions. Forest ownership is addressed through the theory of psychological ownership. On the basis of 15 thematic in-depth interviews, we suggest that a sense of identity and control, as dimensions of psychological ownership, can influence whether forest management decisions are guided by tradition, economic incentives, or responsibility toward property. Based on the results, a forest owner typology (restricted, indifferent, informed, and detached forest owners) was constructed, further enabling us to understand the differences among private forest owners and the roots of their forest management decisions. More generally, the study highlights the important role of emotions in forest management decisions.  相似文献

The heterogeneous nature of non-industrial private forest (NIPF) owners and the challenge this heterogeneity presents for effective policy and program design and delivery is widely recognised. Understanding the socio-economic and motivational differences between various types of landowners will better equip policymakers and forest extension professionals to design policies and programs that efficiently promote private sector timber production and forest conservation outcomes. The purpose of this study was to develop a survey-based empirical typology of Tasmanian NIPF owners based on their stated objectives of forest ownership and to relate owner type to a range of observable property and owner characteristics as well as to timber harvesting and forest management behaviour. Using principal component analysis (PCA) followed by means cluster analysis, four distinct groups are identified: income and investment owners, non-timber output owners, agriculturalists, and multi-objective owners. Members of these groups are found to differ significantly in terms of their personal and property characteristics, as well as their timber harvesting and management behaviour. For example, members of the non-timber output owners, who are motivated solely by objectives related to the production and protection of the non-timber outputs of forests, have similar proportions of timber on their property, but are less likely to have harvested timber from their property, than all other groups.  相似文献

Forest policy in Denmark aims to increase the environmental values of forests. For policy implementation it is essential to know how to motivate private owners. Based on a survey among private forest owners in Denmark, four types of owners have been identified, clustered according to their forest management attitudes and practices: (1) the production-oriented owner, (2) the classic forest owner, (3) the environmental/recreational owner, and (4) the indifferent forest owner. Owners in Clusters 1 and 2 are mainly motivated by financial and wood production aspects, whereas owners in Cluster 3 are to a greater extent motivated by environmental and recreational aspects. Cluster 4 is the least motivated cluster. For effective policy intervention, the clusters should be addressed by different means. Owners in Clusters 1 and 2 should be met on their agricultural-production logic, Cluster 3 on their interest to improve environmental values, whereas owners in Cluster 4 might mainly be interested in passive nature management solutions.  相似文献

Non-industrial private forest owners in Sweden are encouraged to mitigate environmental damages from forestry on their properties under a principle of “freedom with responsibility,” although the level of mitigation is generally left to the owners’ discretion. One voluntary measure private forest owners are encouraged to take is setting aside a part of their productive forests for conservation. The purpose of this paper is to evaluate how non-industrial private forest owner beliefs concerning both their own and the Swedish state’s responsibility for nature protection differ among owners of certified forests, who automatically leave a set-aside, and those who have stayed out of forest certification but have decided to leave a set-aside. Results of a Heckman selection bivariate probit model show that the more a respondent believes the state is responsible for fulfilling environmental goals compared to private forest owners, the less likely it is that an owner of a non-certified forest will leave a set-aside for conservation. Beliefs about responsibility do not, however, differ among owners of certified and non-certified forests. From a policy perspective, Swedish government agencies may have difficulty steering specific measures taken by private forest owners who are interested in conservation but have stayed out of forest certification regimes.  相似文献

More than half of the forest land in Bavaria belongs to private forest owners, who contribute a large amount of the industrial timber supply. The level of information about private forests is in comparison to the communal forests inadequate. The increasing demand for data about the forest sector in Bavaria can be partially covered by regular inventories but requires supplementary monitoring activities. Regular surveys based on voluntary participation deliver data, but often do not fulfil statistical requirements due to low response rates of 15–20% to postal surveys. The Bavarian annual postal cutting survey has been built up over 5 years using a roster of voluntary participants. This pragmatic and cost-effective approach provides reliable data for statistical purposes and gives insight in the forest management activities of small-scale forest owners. Recent technical developments, in particular the availability of grids and digital land-use maps, facilitate the random sampling of forest owners. This approach has been applied in a climate change project, but the results did not meet the expectations because of low response rates. The rather labour- and cost-intensive census of forest owners as applied in the project in Eastern Bavaria cannot be recommended except in exceptional circumstances. In the described project a qualitative approach with four distinct questionnaires has been adopted in order to identify ways to reach forest owners that are either not interested in their forests or do not respond to requests. Due to low response rates the objectives of the study could only be partially achieved.  相似文献

The transformation of the forest sector toward a bioeconomy calls for finding new sources of competitive advantage for the whole sector to retain its future viability. Non-industrial private forest owners are an important group of actors in the Finnish forest-based sector, as they supply 80% of industrial roundwood and control numerous other tangible and intangible forest-based ecosystem services. Our study analyzes forest owner views on the future use of forests in Finland, their perceptions on the evolving sectorial interlinkages and the position of the forest sector now and in the future bioeconomy. The data were collected in two phases: through telephone interviews of forest owners (n?=?278) and four focus group (FG) discussions (n?=?17), and were analyzed both qualitatively and quantitatively. The interviews showed that forest owners consider the highest potential for strengthening the sector toward bioeconomy to come from collaboration with energy and construction businesses. During the FG phase, we identified new possibilities founded on forest-based recreational services, cooperation with nature-based tourism and in increasing value-added wood products. In total, forest owners as a high-involvement group emphasized future value creation to be based upon forest ecosystem services and in diversifying the utilization of forests beyond the dominant raw material-driven mindset.  相似文献

All too often, a small, private forest property fails to meet its potential for the owner or for the community. This is particularly true of depopulating rural areas in industrialized countries where community demographics are changing most. Some attention has recently been given to rural tourism as an option to assist Asian farmers in these circumstances, but what of its potential to assist small-scale forestry producers? This paper examines a population of small forest property owners in Hokkaido Prefecture, Japan. The paper assesses the receptiveness of this community of forest owners to the idea of tourism in their forests. Using original survey data, the paper illustrates that private forest owners’ openness to tourism is strongly related to their interpretation of ‘forest’ in metaphorical terms. The paper concludes by suggesting the best way to pursue the development of ‘forest tourism’ in this community is to rely on the forest owners cooperative to re-package the concept as a ‘secondary forest use’, more closely reflecting forest owners’ interpretations of the forest resource.  相似文献

Given the high percentage of private forest ownership in Finland, family forest owners have an important role in mitigating climate change. The study aims to explore Finnish family forest owners’ perceptions on climate change and their opinions on increasing carbon storage in their forests through new kinds of management activities and policy instruments. The data consists of thematic face-to-face interviews among Helsinki metropolitan area forest owners (n?=?15). These city-dwellers were expected to be more aware of and more interested in climate change mitigation than forest owners at large. Forests as carbon fluxes appear to be a familiar concept to most of the forest owners, but carbon storage in their own forests was a new idea. Four types concerning forest owners’ view on storing carbon in their forests could be identified. The Pioneer utilizes forestland versatilely and has already adopted practices to mitigate climate change. The Potential is concerned about climate change, but this is not seen in forest practices applied. The Resistant is generally aware of climate change but sees a fundamental contradiction between carbon storing and wood production. The Indifferent Owner believes that climate change is taking place but does not acknowledge a relation between climate change and the owner’s forests.  相似文献

Ample research on private forest owners (PFOs) has established high heterogeneity in owners' objectives, motivations and management decisions. Such heterogeneity is, however, rarely taken into account in forest scenario modelling. This study, in contrast, conducts a detailed forest owner mapping that feeds into simulations of ecosystem services (ES) under alternative future scenarios. First, we identify four private forest owner types (FOT) – Forest Businessmen, Household Foresters, Passive Forest Lovers, and Ad Hoc Owners through in-depth interviews and qualitative analyses on a case study area in western Lithuania. Next, each forest estate and forest compartment is assigned a FOT by combining the property registry and forest characteristics with opinions of two types of local experts: state forest managers and inspectors from the State Forest Service. Third, a set of forest management (FM) programmes is specified using field interviews and desktop research, FM records, and expert judgement for each forest compartment. Finally, ES provision is projected using a behavioural matrix combining management styles of FOTs with details of FM programmes. We simulate the dynamics of profits from forestry activities, accumulated carbon in live biomass and tree species diversity under a reference scenario without substantial changes; and a policy intervention scenario. The study demonstrates that treating forest owners as a homogenous group overestimates profits from timber and underestimates the provision of the other analysed ES, potentially misinforming policy decisions.  相似文献

The development of private ownership is an important outcome of structural changes for the whole economy as well as for the forestry sector in Estonia. Cooperation between forest owners has been seen as one possibility for increasing the provision of various forest-related benefits and goods. Yet the extent of cooperation between forest owners is still not at a sufficient level, but the reasons have not been extensively studied. The authors’ aim was to find out the key determinants for forest owners to join a forest owner association and to explore how cooperation between owners could be increased. Survey data were used to divide the respondents into two groups according to whether they were members of forest owners associations or not. It was found that one key aspect is the size of the forest property—association members usually manage larger forest areas than non-members. In addition, the members tend to be more active and consistent in forest management activities than non-members. Also there is potential towards cooperation within non-members as their plans for the future are much more targeted. Although there are limits to voluntary cooperation, a huge potential for Estonian private forest owners could be realised by diversifying forest owner association activities and services to meet the different expectations of forest owners.  相似文献

The consumption of energy wood in Finland has increased dramatically since the early 2000s, and the region of South Savo is a bellwether for its usage across the country. This increase is partly due to the national policy of sustainable energy, region's wealth of forests but is also dependent on non-industrial private forest owners (NIPF) deciding to sell energy wood. In this study, a survey with a structured questionnaire was conducted among the NIPFs in the region of South Savo to enlarge the understanding of their willingness to sell energy wood in the future and adopt new approaches to forestry that involves energy wood thinning as well as their current production of energy wood. Moreover, the factors influencing forest owner's motivations relating to energy wood thinning as well as information needs were analysed with multivariate techniques. The results show that almost half of the forest owners in the South Savo region had not sold energy wood. However, forest owners within the region generally had positive attitudes towards selling small-sized energy wood and forestry methods that involve energy wood thinning. Moreover, forest owners' willingness to sell different types of energy wood varied, depending on their background. The study suggests that the increase in supply of energy wood presumes both intensified extension services for forest owners and markets that are better organised than at the moment. The results may also prove beneficial in informing policy-makers regarding which specific target group(s) to focus on when promoting energy wood sales among NIPFs and which aspects of energy wood harvesting and sales to promote.  相似文献

As global competition increases for wood-based products, the need for more efficient supply chains becomes increasingly important. In the forest products sector, these supply chains involve individuals and firms ranging from private forestland owners with standing timber to factories producing final finished products. Long-term timber leases are one mechanism that can be used to develop access to timber supplies for companies unable or unwilling to purchase land outright for growing timber. To investigate private forest owner opinions and attitudes regarding long-term timber leases, we conducted a survey of landowners from Wetzel county, West Virginia. No long-term leases were reported by respondents, but 24% claimed they would enter a lease under certain conditions. The most frequently listed concern related to long-term timber leases was for the “loss of control”. Results of this survey are discussed in the light of forest management efforts that might be used to improve the social, financial, and environmental benefits for private forest owners.  相似文献

Climate change is a global concern. Within Nordic countries such as Finland it has particular influence on the use of natural resources. Family forest owners own 61% of the forested land in Finland and 80% of the industrial roundwood purchased comes from these forest owners. Thus how private forest owners approach climate change is of high national economic and ecological importance. In order to understand family forest owners' perspectives on climate change in their own forests, qualitative interviews along walks through the owner's forests were conducted. Analysis of the conversations during these walks highlighted that forest owners discussed the phenomenon without prompting more often than hypothesized. Additionally, forest owners were less certain as to the causes of changes observed in their forests, mostly willing to take advice from professionals, and economically-driven in their response. For those forest owners who did express concern regarding climate change, they were at a loss for ways their efforts could make a meaningful difference. The prevalent uncertainty among forest owners calls for guidance from authority. Policy practices should make an effort to combine monetary incentives along with climate change focused forest management practices. Additionally, forest owner's reliance on the advice and expertise of forestry professionals should be utilized when pursuing climate-motivated forest management.  相似文献

The number of family forest owners in the USA has increased continuously in recent decades, and the fate of much of US forests lies in the hands of this diverse and dynamic group of people. The National Woodland Owner Survey (NWOS) is a recurring and comprehensive national survey of US private forest owners, including family forest owners. The NWOS includes an open-ended question that explores forest owners’ motivations and values related to their woodland. The open-ended question format allows respondents to express their own frame of reference in their own words, rather than respond to predetermined, fixed-response categories of motivations. This paper describes the system of values and motivations that emerged from analysis of responses to the open-ended question, and compares these findings to a closed-ended, fixed-response question also included in the NWOS. Diverse and multidimensional motives were expressed by respondents. Eight broad categories and 37 sub-categories of motives and values emerged from analysis of the open-ended question. The fixed categories of the closed-ended question failed to capture many dimensions of forest owner motivations. A more detailed, qualitative understanding of forest owner motivations and values is needed to provide extension foresters and others who work with family forest owners important insights and help guide public policy related to private forestland. Open-ended survey questions can help provide such understanding.  相似文献

Biomass plays a vital role in the energy supply of many developing countries. It is the major energy source for the rural population of Nepal, where 70 % of the total energy is derived from woody plant biomass in the form of fuelwood. The main aim of this study is to describe the fuelwood consumption pattern and the role of community forests and trees on private farmland in biomass supply to rural households in Nepal. The study investigates whether demography and socioeconomic attributes of households affect fuelwood consumption. A household survey was conducted, along with measurements of fuelwood mass for six community forest user groups in Dolakha district of Nepal. Average daily household fuelwood consumption was estimated to be 8.4 kg, giving a mean annual consumption of 3060 kg per household. Per capita fuelwood consumption per day was found to be 1.7 kg. Total fuelwood consumption of households is significantly correlated with household size, ownership of cultivated irrigated terraces and number of livestock per household, and negatively significantly correlated with ownership of cultivated rain-fed terraces. Fuelwood consumption varies significantly between seasons. Among various sources of biomass energy, fuelwood from community forests contributes 23 % and trees on private farmland contribute 12 %. The rest is provided from other biomass sources, including the remains of fodder collected from private farmland vegetation, wood previously used for fences and trellises in private farmland, crop residues, and purchased fuelwood.  相似文献
