The State and the Development of Industrial Plantation Forest

Directory of Open Access Journals (Sweden)

2015-02-01

Full Text Available Development of industrial plantation forest is a form of principal-agent relationship, in which the Ministry of Forestry as a principal gives utilization permit to the entrepreneur as an agent, known as the Forest Timber Product Exploitation Permit on Planted Forest. This utilization permit obtained by the agents is operationally conducted by other parties through a cooperative agreement. The purpose of this study is to obtain an information regarding to the state position in the development of industrial plantation forest. The study was conducted in Riau Province, using the constructivist paradigm with phenomenological method. Data were obtained through in-depth interviews to selected informants. Data were also obtained from the review of documents to complement the interview. Data analysis was conducted using property rights and principal agent theories. The phenomenon of multi-chain transfer of the management rights of plantation forest that occoured in the observed companies showed that the state was unable to effectively control to the forest plantation. The study recommends that state should issue regulation to decrease or stops further transfer of the management rights of plantation forest. However, further study needs to overcome the existing over accumulation of plantation forest in a few hands.Keywords: industrial plantation forest, property right, principal agent, the state position, authority

Strategic choices: Swedish climate intervention policies and the forest industry's role in reducing CO2 emissions

International Nuclear Information System (INIS)

Nystroem, Ingrid; Cornland, Deborah W.

2003-01-01

Given adequate incentive, the forest industry could play a significant role in achieving Swedish objectives for reducing CO 2 emissions. Whether or not this potential can be harnessed depends on the types of energy policy interventions that are introduced. An analysis of the potential impacts of four policy-intervention strategies on the forest industry is presented in this article. The focus of the analysis is on the four strategies' impacts on forest industry electricity demand from, and renewable energy supply to, the energy system. The strategies analyzed include a reference strategy and strategies targeting electricity production, transportation and the energy system as a whole. The method applied combines scenario analysis with systems engineering modeling. Separate scenario sets were used to reflect visions of development from the forest industry and the energy sector. Separate models were used to enable a more in-depth analysis of the forest industry's role than is commonly the case in energy systems engineering studies

Is sustainable development attainable? Challenges facing forestry and the forest products industry

International Nuclear Information System (INIS)

Wrist, P.E.

1991-01-01

The challenges that face the forest industry in achieving sustainable development are reviewed. Sustainable development is not the same as sustained yield forest management. While sustained yield limits harvesting to an estimate of a forest's incremental annual growth, it is a policy which neither takes into account how improved forest management practices can increase future growth rates nor gives guidance on how multiple uses for the forest resource can be made compatible with periodic harvesting of that resource. Forests, in addition to meeting demands for timber production, must also meet demands for watershed management, recreation, preservation of wildlife and genetic diversity, moderation of climates, carbon sequestration, and land reclamation. Information is lacking from which to develop improved forest management programs that take these demands into account. Questions remain about such matters as the role of plantations in sustainable forestry and the maintenance of natural diversity. Some recent research being undertaken to generate better information for future forestry decision making is outlined, including work on gene pool maintenance, the interdependence of forest ecology and climate, the symbiotic role of mycorrhiza, forest fertilization, and the interdependence of sustainable forestry and sustainable fisheries. In the forest products industry, engineered wood products have been developed that meet tight specifications and require less raw material, and process changes have been introduced that greatly reduce pollutants from pulp manufacture

Effect of industrial pollution on behaviour of radionuclides in forest ecosystems

International Nuclear Information System (INIS)

Outola, I.

2009-01-01

To investigate how and to what extent industrial pollution affects the behaviour of radionuclides in forest ecosystems, studies were conducted in the vicinity of two Cu-Ni smelters: one in a pine forest at Harjavalta, Finland, and the other in a spruce forest at Monchegorsk, Russia. Industrial pollution had significant effects on the distribution of radionuclides in soil horizons. With the increase in pollution towards the smelter, radionuclides were accumulated more in the litter layer because the conversion of litter into organic material was diminished due to inhibited microbial activity. As a result, the organic layer contained less radionuclides towards the smelter. The effect of industrial pollution on soil-to-plant transfer was complex. The effect varied with radionuclide, plant species and also on forest type. For 137 Cs, soil-to-plant transfer decreased significantly as industrial pollution increased in pine forest, whereas the decrease was less pronounced in spruce forest. Root uptake of 239,240 Pu by plants is extremely small, and plant contamination by resuspended soil is an important factor in considering the soil-to-plant transfer of this radionuclide. In spruce forest, more plutonium was transferred into plants when pollution load increased due to resuspension of litter particles, which contained higher concentrations of plutonium in the vicinity of the smelter. Soil-to-plant transfer of plutonium was much less affected in pine forests contaminated with industrial pollution. This research clearly indicates the sensitivity of the northern forest ecosystem to inorganic pollutants. Prediction of the soil-to-plant transfer of radionuclides in industrially polluted forest ecosystems requires detailed information on the total deposition, vertical distribution of radionuclides in soil, soil microbiological factors, other soil parameters as well as the rooting depths of the plants.

Industry and forest wetlands: Cooperative research initiatives

International Nuclear Information System (INIS)

Shepard, J.P.; Lucier, A.A.; Haines, L.W.

1993-01-01

In 1989 the forest products industry responded to a challenge of the National Wetlands Policy Forum to initiate a cooperative research program on forest wetlands management organized through the National Council of the Paper Industry for Air and Stream Improvement (NCASI). The objective is to determine how forest landowners can manage wetlands for timber production while protecting other wetland functions such as flood storage, water purification, and food chain/wildlife habitat support. Studies supported by the NCASI in 9 states are summarized. Technical support on wetland regulatory issues to member companies is part of the research program. Since guidelines for recognizing wetlands for regulatory proposed have changed frequently, the NCASI has recommend an explicit link between wetland delineation and a classification system that considers difference among wetland types in vegetation, soils, hydrology, appearance, landscape position, and other factors. 16 refs

Analyses of the Competitiveness of Forest Industry in the Republic of Macedonia

Nenad Savić

2011-06-01

Full Text Available Background and Purpose: This paper gives a thorough picture of the competitiveness characteristics of the Macedonian forest based industry for the period 1993 to 2006, from its independence to present times. The main purpose of this study is to analyze competitiveness of Macedonian forest industry and the factors that influences the creation and development of competitive advantages. Material and Methods: The study is based on theoretical tool of the Porter`s ''diamond'' model of the national competitiveness using four linked factors like: factor conditions, demand factor, firm’s strategy, rivalry and structure and the forth one, related and supported industries. The method used is case study which includes collection of quantitative data, gathered through documentation, archival records, academic literature, publications, journals and websites. Results and Conclusion: The analyzes has shown that the main strengths of Macedonian forest based industry are due to the existence of favorable factor conditions, as a cheap labor and energy cost-compared with region, good geographic location and relatively decent transport infrastructure. Weaknesses come from the lack of infrastructural investments (lack of capital, inappropriate management strategies, outdated machinery, low productivity and low value added products. To achieve better results industry should be organised in a better way and further investments in modern technologies and human resources are necessary.

Radiocesium in the forest and forest industry. Studies on the flow, occurrence and technological enhancement of radionuclides in the forest industry with emphasis on the behaviour of radiocesium

International Nuclear Information System (INIS)

Ravila, A.

1998-01-01

In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium-contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ecosystem or its many components. Still, the impact from radioactive fallout on the forest industries that receive the bulk fraction of biomass removed from the forest has scarcely been investigated. Recycling process elements is a necessity in chemical pulping to be competitive. The chemical pulping process is primarily designed to extract, separate and recover the digesting agent carriers such as sodium and complementary carriers such as calcium needed for the production of fresh cooking liquors. Besides these chemical elements, unwanted elements in the process such as K and many other chemical elements are also retained as a consequence of their chemical similarity to sodium and calcium. Notably, two such elements are the long-lived fallout fission products radiocesium and radiostrontium which build-up to substantial activities in parts of the pulp mill recovery cycle and in ash and sludge deposits. Improvements of the pulp recovery processes and the striving towards completely closed systems are estimated to yield around 30 GBq 137 Cs per Bq kg -1 of 137 Cs in wood as an upper limit of the radiocesium activity inventory within an average Nordic pulp mill site. In the perspective of new emerging practices for industrial resource management of by-products, radionuclides will not only be transferred from the forest to the industries, but may be returned to the forest with by-products rich in valuable plant nutrients. The radionuclides in the forest soil and trees constitute a source of radiation and the consequences thereof can be evaluated in terms of the resulting absorbed

The Willingness of Non-Industrial Private Forest Owners to Enter California's Carbon Offset Market.

Kelly, Erin Clover; Gold, Gregg J; Di Tommaso, Joanna

2017-11-01

While non-industrial private forest landowners have a significant amount of forest landholdings in the US, they are underrepresented in the California cap-and-trade market forest offset program. Additional participation could benefit both the market and non-industrial private forest landowners. We developed a mail questionnaire which served as both a survey instrument and outreach tool about the market. Questions covered forest ownership objectives, landowners' future plans for forests, views of climate change, and attitudes and intentions regarding forest carbon offset project development. We sampled from five Northern California counties for a total of 143 usable surveys. Three different groups of landowners were identified based on their management objectives: amenity (including protecting nature and recreation); legacy (passing land to children and/or maintaining a farm or ranch); and income. Landowner objective groups differed on several key variables, particularly related to potential motivations for joining the market, while all landowners expressed concerns about protocol requirements. Regardless of ownership objectives, over half expressed that receiving revenue from their forests would be an important motivator to join, though most were unwilling to satisfy protocol requirements, even after learning of the potential benefits of program participation. Thus, participation appears to be limited by the costly and complex project development process, as well as a lack of landowner awareness. Extending these lessons, we assert that different landowners may approach payment for ecosystem services programs with different needs, awareness, and motivations, which provide important lessons for those who conduct landowner outreach and for PES program designers.

Impact of European Union Timber Regulation on Forest Certification Strategies in the Finnish Wood Industry Value Chain

Directory of Open Access Journals (Sweden)

Jani Holopainen

2015-08-01

Full Text Available The aim of this explorative study is to find out how the EU Timber Regulation (EUTR has affected the forest and chain of custody (CoC certification strategies and practices among the Finnish wood industry companies. We are especially interested to find out whether more integrated strategies and collaborative networks have emerged for enhanced communications throughout the industry value chains. This qualitative interview study included both EUTR ex ante and ex post analysis, based on three rounds of managerial and expert interviews during 2011–2015. The results indicate that the EUTR appears to have enforced the supplier–client relations in the Finnish wood industry value chain. The sector still lacks integrated communication strategies with better understanding of customer and stakeholder values, which could contribute to more cohesive communication and marketing efforts reflecting the values of the whole industry. The certification practices are fairly spontaneously implemented following the traditional industry culture, which is not supportive of innovations and gaining competitive advantages in the broader material markets. Furthermore, the existence of two parallel forest certificates (Forest Stewardship Council (FSC and Programme for the Endorsement of Forest Certification (PEFC seems to hamper the effective communication and building of an image of sustainable wood products among customers and end consumers, groups that are also exposed to more general environmental communication, e.g., in the building material markets.

Spatial and Temporal Analysis of Industrial Forest Clearcuts in the Conterminous United States

Science.gov (United States)

Huo, L. Z.; Boschetti, L.

2015-12-01

Remote sensing has been widely used for mapping and characterizing changes in forest cover, but the available remote sensing forest change products are not discriminating between deforestation (permanent transition from forest to non forest) and industrial forest management (logging followed by regrowth, with no land cover/ land use class change) (Hansen et al, 2010). Current estimates of carbon-equivalent emissions report the contribution of deforestation as 12% of total anthropogenic carbon emissions (van der Werf et al., 2009), but accurate monitoring of forest carbon balance should discriminate between land use change related to forest natural disturbances, and forest management. The total change in forest cover (Gross Forest Cover Loss, GFLC) needs to be characterized based on the cause (natural/human) and on the outcome of the change (regeneration to forest/transition to non/forest)(Kurtz et al, 2010). This paper presents the methodology used to classify the forest loss detected by the University of Maryland Global Forest Change product (Hansen, 2013) into deforestation, disturbances (fires, insect outbreaks) and industrial forest clearcuts. The industrial forest clearcuts were subsequently analysed by converting the pixel based detections into objects, and applying patch level metrics (e.g. size, compactness, straightness of boundaries) and contextual measures. The analysis is stratified by region and by dominant forest specie, to highlight changes in the rate of forest resource utilization in the 2003-2013 period covered by the Maryland Forest Cover Change Product.

2015-12-01

The southeast United States (SE-US) is dominated by tree plantations and other forms of industrial forests that provide vital socio-ecological services to the human society. Most of these forests are managed to maximize economic outcome, and hence are often subject to intensive management practices and have different harvest-regrowth cycles as compared with natural forest ecosystems. Through the North American Forest Dynamics (NAFD) study, we have mapped forest disturbances for the conterminous United States using dense time series Landsat observations. The derived map products revealed that more than 50% of the forests in SE-US were harvested or disturbed by other forms of human or natural disturbance events at least once between 1986 and 2010. These products are being analyzed together with ancillary GIS data sets and field inventory data to identify industrial forests and to quantify their logging intensity, timber output, recovery rate, and the harvest-regrowth cycle. The derived results will be summarized in this presentation, along with discussions of the underlying environmental and management factors that may drive the spatio-temporal dynamics of the industrial forests in SE-US.

Deforestation and Industrial Forest Patterns in Colombia: a Case Study

Huo, L. Z.; Boschetti, L.; Sparks, A. M.; Clerici, N.

2017-12-01

The recent peace agreement between the government and the Revolutionary Armed Forces of Colombia (FARC) offers new opportunities for peaceful and sustainable development, but at the same time requires a timely effort to protect biological resources, and ecosystem services (Clerici et al., 2016). In this context, we use the 2001-2017 Landsat data record to prototype a methodology to establish a baseline of deforestation, afforestation and industrial forest practices (i.e. establishment and harvest of forest plantations), and to monitor future changes. Two study areas, which have seen considerable deforestation in recent years, were selected: one in the South of the country, at the edge of the Amazon Forest (WRS path 008 row 059) and one in the center, in mixed forest (WRS path 008 row 055). The time series of all the available cloud free Landsat 5, Landsat 7 and Landsat 8 data was classified into a sequence of binary forest/non forest maps using a deep learning model, successfully used in the natural language processing field, trained to detect forest transitions. Recurrent Neural Networks (RNN) is a class of artificial neural network that extends the conventional neural network with loops in the connections (Graves et al., 2013). Unlike a feed-forward neural network, an RNN is able to process the sequential inputs by having a recurrent hidden state whose activation at each step depends on that of the previous steps. In this manner, the RNN provides a good framework to dynamically model time series data, and has been successfully applied to natural language processing in Google (Sutskever et al., 2014). The sequence of forest cover state maps was subsequently post-processed to differentiate between deforestation (e.g. transition from forest to non forest land use) and industrial forest harvest (i.e. timber harvest followed by regrowth), by integrating the detection of temporal patterns, and spatial patterns.

Annual and monthly-based emission inventories in northern, central and north-eastern provinces in Thailand, where agriculture and related agro-industries are very intensive, were estimated to evaluate the contribution of agricultural activity, including crop residue burning, forest fires and related agro-industries on air quality monitored in corresponding provinces. The monthly-based emission inventories of air pollutants, or, particulate matter (PM), NOx and SO 2 , for various agricultural crops were estimated based on information on the level of production of typical crops: rice, corn, sugarcane, cassava, soybeans and potatoes using emission factors and other parameters related to country-specific values taking into account crop type and the local residue burning period. The estimated monthly emission inventory was compared with air monitoring data obtained at monitoring stations operated by the Pollution Control Department, Thailand (PCD) for validating the estimated emission inventory. The agro-industry that has the greatest impact on the regions being evaluated, is the sugar processing industry, which uses sugarcane as a raw material and its residue as fuel for the boiler. The backward trajectory analysis of the air mass arriving at the PCD station was calculated to confirm this influence. For the provinces being evaluated which are located in the upper northern, lower northern and northeast in Thailand, agricultural activities and forest fires were shown to be closely correlated to the ambient PM concentration while their contribution to the production of gaseous pollutants is much less.

Full Text Available Improvements in the management of pine plantations result in multiple industrial and environmental benefits. Remote sensing techniques can dramatically increase the efficiency of plantation management by reducing or replacing time-consuming field sampling. We tested the utility and accuracy of combining field and airborne lidar data with Random Forest, a supervised machine learning algorithm, to estimate stem total and assortment (commercial and pulpwood volumes in an industrial Pinus taeda L. forest plantation in southern Brazil. Random Forest was populated using field and lidar-derived forest metrics from 50 sample plots with trees ranging from three to nine years old. We found that a model defined as a function of only two metrics (height of the top of the canopy and the skewness of the vertical distribution of lidar points has a very strong and unbiased predictive power. We found that predictions of total, commercial, and pulp volume, respectively, showed an adjusted R2 equal to 0.98, 0.98 and 0.96, with unbiased predictions of −0.17%, −0.12% and −0.23%, and Root Mean Square Error (RMSE values of 7.83%, 7.71% and 8.63%. Our methodology makes use of commercially available airborne lidar and widely used mathematical tools to provide solutions for increasing the industry efficiency in monitoring and managing wood volume.

Full Text Available International market requires producers to proof the legality of their wood products to address the issues of illegal logging and illegal trade. Timber Legality Verification System (TLVS has been prepared by the Government of Indonesia that covering the upstream and downstream wood industries. This paper aims to evaluate gaps in the implementation of TLVS policy and its impact on the sustainability of timber industry. This study was using gap, descriptive and costs-structure analyzes. The study was conducted in three provinces, namely: DKI Jakarta, West Java and D.I. Yogyakarta. Research found that the effectiveness of the TLVS implementation was low due to relatively rapid policy changes. This situation became disincetive for investments in timber business. Private sector perceived that TLVS policy should be applied in the upstream of timber business. Hence, the industry and market in the downstream have not been fully support to this system. Furthermore, TLVS policy implementation was considered ineffective by timber industry as well as private forest managers, especially by micro industry and smallholder private forests. This situation threatened the sustainability of timber industry and private forests. Therefore, Institutions should be strengthened in order to improve the quality of human resources and the competitiveness of products.

Assessing potential forest and steel inter-industry residue utilisation by sequential chemical extraction

Energy Technology Data Exchange (ETDEWEB)

Makela, M.

2012-10-15

Traditional process industries in Finland and abroad are facing an emerging waste disposal problem due recent regulatory development which has increased the costs of landfill disposal and difficulty in acquiring new sites. For large manufacturers, such as the forest and ferrous metals industries, symbiotic cooperation of formerly separate industrial sectors could enable the utilisation waste-labeled residues in manufacturing novel residue-derived materials suitable for replacing commercial virgin alternatives. Such efforts would allow transforming the current linear resource use and disposal models to more cyclical ones and thus attain savings in valuable materials and energy resources. The work described in this thesis was aimed at utilising forest and carbon steel industry residues in the experimental manufacture of novel residue-derived materials technically and environmentally suitable for amending agricultural or forest soil properties. Single and sequential chemical extractions were used to compare the pseudo-total concentrations of trace elements in the manufactured amendment samples to relevant Finnish statutory limit values for the use of fertilizer products and to assess respective potential availability under natural conditions. In addition, the quality of analytical work and the suitability of sequential extraction in the analysis of an industrial solid sample were respectively evaluated through the analysis of a certified reference material and by X-ray diffraction of parallel sequential extraction residues. According to the acquired data, the incorporation of both forest and steel industry residues, such as fly ashes, lime wastes, green liquor dregs, sludges and slags, led to amendment liming capacities (34.9-38.3%, Ca equiv., d.w.) comparable to relevant commercial alternatives. Only the first experimental samples showed increased concentrations of pseudo-total cadmium and chromium, of which the latter was specified as the trivalent Cr(III). Based on

Reducing Electrical Consumption in the Forest Products Industry Using Lean Thinking

Directory of Open Access Journals (Sweden)

Scott William Lyon

2014-01-01

Full Text Available The forest products industry has an opportunity to reduce energy costs using energy management practices, thereby boosting its global competitiveness. Increasing manufacturing costs have contributed significantly to the decline of the forest products manufacturing industries in the U.S.; these increasing costs limit manufacturers’ abilities to compete with their global competitors. U.S. companies are continually improving their products, processes, finances, and business practices to better compete with global marketplaces; however, they may not be seizing all of the opportunities available through more efficient energy consumption practices. By eliminating non-valued added activities, lean thinking is an example of one tool that may improve performance and reduce costs. A case study was conducted at a cabinet manufacturer in Virginia to examine the impact of lean thinking on the consumption of electricity in the manufacturing process. An energy management system was used to provide rapid feedback on electrical energy consumption for production operations. Significant changes were observed after implementing energy reduction practices identified by lean thinking tools.

Energy and industrial wood harvesting from young forests; Energia- ja ainespuun korjuu nuorista metsistae

Energy Technology Data Exchange (ETDEWEB)

Rieppo, K.; Mutikainen, A.; Jouhiaho, A. (eds.)

2011-07-01

In the METKA Forest Energy Profitably project TTS (Work Efficiency Institute) compared methods suitable for the harvesting of energy wood and industrial wood. During the thinning of a young forest by a forest worker, the whole-tree logging method was one-third less expensive than the pulpwood method, including terrain transport. In harvesting whole trees as part of the thinning of young forests, methods based on combinations of manual and mechanized workproved to be several dozen per cent less expensive than the entirely mechanized method. When cutting energy wood with a Harveri small harwarder productivity was slightly higher when using 40-metre distances two cutting trails than when using 20-metre distances. When using a Tehojaetkae small harvester, creating two cutting trails in addition to the standard four-metre-wide cutting trail resulted in slightly higher productivity than creating three narrow cutting trails. A Risutec L3A energy head was used in tests involving both clearing and energy wood cutting. This method proved to be very promising, and it seems highly proable that advance clearing will no longer be needed in energy wood harvesting under all circumstances. When using traditional harvester-forwarder chains and a harvarder for first thinning in pine stands, the harvesting of entirely or partly non-delimbed trees was 20 to 40 per cent less expensive per harvested cubic meter than the harvesting of delimbed trees. In tests carried out using the Naarva RS25 harvester head for first thinning in pine stands, the integrated method resulted in approximately one-third productivity than the traditional cutting of industrial wood. In a spruce-dominant site with delayed first thinning, the unit costs of harvesting delimbed energy wood were 16 per cent lower than those of the harvesting of pulpwood. In the future development of machinery, it will be important to aim at continuous motion, at least in terms of cutting small trees. (orig.)

Forecasting energy demand and CO{sub 2}-emissions from energy production in the forest industry

Energy Technology Data Exchange (ETDEWEB)

Malinen, H

1998-12-31

The purpose of this study was to develops new energy forecasting methods for the forest industry energy use. The scenarios have been the most commonly used forecasts, but they require a lot of work. The recent scenarios, which are made for the forest industry, give a wide range of results; e.g. from 27,8 TWh to 38 TWh for electricity use in 2010. There is a need for more simple and accurate methods for forecasting. The time scale for the study is from 1975 to 2010, i.e. 36 years. The basic data for the study is collected from time period 1975 - 1995. It includes the wood use, production of main product categories and energy use in the forest industry. The factors affecting energy use at both industry level and at mill level are presented. The most probable technology trends, which can have an effect on energy production and use and CO{sub 2}-emissions are studied. Recent forecasts for the forest industry energy use till the year 2010 are referred and analysed. Three alternative forecasting methods are studied more closely. These methods are (a) Regression analysis, (b) Growth curves and (c) Delphi-method. Total electricity demand, share of purchased electricity, total fuel demand and share of process-based biofuels are estimated for the time period 1996 - 2010. The results from the different methods are compared to each other and to the recent scenarios. The comparison is made for the results concerning the energy use and the usefulness of the methods in practical work. The average energy consumption given by the forecasts for electricity was 31,6 TWh and for fuel 6,2 Mtoe in 2010. The share of purchased electricity totalled 73 % and process based fuels 77 %. The figures from 1995 are 22,8 TWh, 5,5 Mtoe, 64 % and 68 % respectively. All three methods were suitable for forecasting. All the methods required less working hours and were easier to use than scenarios. The methods gave results with a smaller deviation than scenarios, e.g. with electricity use in 2010 from

Sharma, Naman; Nainwal, Shubham; Jain, Shivani; Jain, Siddharth

2015-11-01

The production of biofuels as alternative energy source over fossil fuels has gained immense interest over the years as it can contribute significantly to reduce the greenhouse gas (GHG) emissions from energy production and utilization. Also with rapidly increasing fuel price and fall in oil wells, the present scenario forces us to look for an alternative source of energy that will help us in the operation of industrial as well as the transportation sector. The pulp mills in India are one of the many options. The pulp mills in India can help us to produce bio-fuels by thermo-chemical/biochemical conversion of black liquor and wood residues. These technologies include extraction of hemi-cellulose from wooden chips and black liquor, lignin from black liquor, methanol from evaporator condensates, biogas production from waste sludge, syngas production from biomass using gasification and bio-oil production from biomass using pyrolysis. The objective of this paper is to overview these emerging bio-refinery technologies that can be implemented in Indian Forest Industry to get bio-fuels, bio-chemicals and bio-energy to reduce GHG emissions.

Coordinating the Uncoordinated: The EU Forest Strategy

Directory of Open Access Journals (Sweden)

Filip Aggestam

2018-03-01

Full Text Available The second European Union (EU Forest Strategy responds to new challenges facing both forests and the forest-based sector which highlights the EU’s need for a policy framework ensuring coordination and coherence of forest-related policies. The objective of the present article is to analyse whether the new Strategy contributes towards horizontal policy coherence of EU forest-related policies, given its shared and exclusive competences. This is achieved by comparing European Commission and forest industry policy priorities as articulated in the Strategy and through research carried out for the recent Cumulative Cost Assessment (CCA of forest-based industries. Results from the comparative analysis demonstrate that the Strategy does not address many EU policies and policy instruments that affect the whole forest value chain and that it clearly omits existing EU policy instrument objectives that entail significant costs for the forest-based industry. It is therefore argued that without coordinating collective EU goals and gathering strong political support, it is at best extremely difficult or at worst impossible, to achieve coherence for EU forest-related policies across the whole forest value chain. Improving coherence of Union forest-related policies will require the Strategy to address more policy areas and instruments, including clearly defined parameters of what constitutes an EU forest-related policy. These pressing needs reach beyond what the Strategy presently sets out to achieve.

Including Effects of Water Stress on Dead Organic Matter Decay to a Forest Carbon Model

Science.gov (United States)

Kim, H.; Lee, J.; Han, S. H.; Kim, S.; Son, Y.

2017-12-01

Decay of dead organic matter is a key process of carbon (C) cycling in forest ecosystems. The change in decay rate depends on temperature sensitivity and moisture conditions. The Forest Biomass and Dead organic matter Carbon (FBDC) model includes a decay sub-model considering temperature sensitivity, yet does not consider moisture conditions as drivers of the decay rate change. This study aimed to improve the FBDC model by including a water stress function to the decay sub-model. Also, soil C sequestration under climate change with the FBDC model including the water stress function was simulated. The water stress functions were determined with data from decomposition study on Quercus variabilis forests and Pinus densiflora forests of Korea, and adjustment parameters of the functions were determined for both species. The water stress functions were based on the ratio of precipitation to potential evapotranspiration. Including the water stress function increased the explained variances of the decay rate by 19% for the Q. variabilis forests and 7% for the P. densiflora forests, respectively. The increase of the explained variances resulted from large difference in temperature range and precipitation range across the decomposition study plots. During the period of experiment, the mean annual temperature range was less than 3°C, while the annual precipitation ranged from 720mm to 1466mm. Application of the water stress functions to the FBDC model constrained increasing trend of temperature sensitivity under climate change, and thus increased the model-estimated soil C sequestration (Mg C ha-1) by 6.6 for the Q. variabilis forests and by 3.1 for the P. densiflora forests, respectively. The addition of water stress functions increased reliability of the decay rate estimation and could contribute to reducing the bias in estimating soil C sequestration under varying moisture condition.

Ratnaningsih, Ambar Tri; Rayahu Prasytaningsih, Sri

2017-12-01

Riau Province has a high threat to forest fire in peat soils, especially in industrial forest areas. The impact of fires will produce carbon (CO2) emissions in the atmosphere. The magnitude of carbon losses from the burning of peatlands can be estimated by knowing the characteristics of the fire peat and estimating CO2 emissions produced. The objectives of the study are to find out the characteristics of fire-burning peat, and to estimate carbon storage and CO2 emissions. The location of the research is in the area of industrial forest plantations located in Bengkalis Regency, Riau Province. The method used to measure peat carbon is the method of lost in ignation. The results showed that the research location has a peat depth of 600-800 cm which is considered very deep. The Peat fiber content ranges from 38 to 75, classified as hemic peat. The average bulk density was 0.253 gram cm-3 (0.087-0,896 gram cm-3). The soil ash content is 2.24% and the stored peat carbon stock with 8 meter peat thickness is 10723,69 ton ha-1. Forest fire was predicted to burn peat to a depth of 100 cm and produced CO2 emissions of 6,355,809 tons ha-1.

Accounting for social impacts and costs in the forest industry, British Columbia

International Nuclear Information System (INIS)

Gale, Robert; Gale, Fred

2006-01-01

Business reviews of the forest industry in British Colombia, Canada, typically portray an unequivocally positive picture of its financial and economic health. In doing so, they fail to consider the following six categories of social impacts and costs: (1) direct and indirect subsidies; (2) government support through investment; (3) community dependence; (4) the maintenance of public order; (5) aboriginal title; and (6) the overestimation of employment. Our findings show that conventional economic and financial accounting methods inflate the industry's net contribution to the economy. We make a number of recommendations to address this shortcoming to improve future accounting and reporting procedures

Production and processing of fuel by the forest industry - opportunities and conditions

International Nuclear Information System (INIS)

Magnusson, L.

1991-01-01

The purpose of this study was to illustrate the opportunities for the forest industry to establish a system of handling and processing biofuels in conjunction with their existing activities, and which would supply a future market for biofuels in, for example, electricity generation. The sawmills report that it is difficult today to find a market for fuel products, especially for sawmills at greater distances from larger biofuel-consuming plants. The sawmills show great interest in cogeneration in their own plants, but report difficulties in achieving profitability. The main problem is reported to be that the price of the surplus electricity delivered to the grid is too low, but also that the electricity prices today are so low that it is difficult to justify even generating electricity for the mill's own use. There is an interest in the paper and pulp industry for integrated methods and production of biofuels since the part-tree methods used, at least in some parts of Sweden, are considered to contribute also to an increase in the availability of pulp wood to the industry. A fundamental viewpoint is, however, that the plants are built for the primary purpose of producing pulp or paper. It is unlikely that the industry would give priority to investments for production of a new secondary product in the form of fuel products, particularly when the conditions today imply that there are few possibilities to achieve any particular profitability. The most probable solution is that the fuel is processed outside the industry by other parties, e.g., the forest divisions. In the long term, increased efficiency in the processes may lead to a primary heat surplus which could be used to produce processed fuels

The energy research project of the mechanical forest industry studied the energy consumption in 1979 and the possibilities to save energy in the sawmill, plywood, particleboard, fibreboard, joinery, wooden houses, gluelam and impregnation industries. The energy consumption per product unit is on the minimum level in sawmilling, 1.38 GJ/m/sup 3/, and on the maximum level in fibreboard manufacturing, 9.98 GJ/t. In plywood production, 6.95 GJ/m/sup 3/, the energy consumption is about double compared with the consumption in particleboard production, 3.40 GJ/m/sup 3/. The main part of the energy is heat. In the drying process about 70-85% of the total energy is used in individual processes. Over a half, 53.9%, of the total energy consumption, 23 169 TJ, is used in sawmill industry. The proportion of plywood industry is 19.2%, of particleboard industry 12.2% and of fibreboard industry 7.2%. The proportion of the processing industry is 7.5%; the main part is used in joinery industry. The fuel consumption in transportation of wooden raw materials was 2 260 TJ and in transportation of products 4 800 TJ. In fibreboard industry it is possible to save energy by leading the waste steam from defibratory into chip silos for preheating of the chips. In veneer and chip drying it is possible to save energy by using higher moisture content of the drying air and by utilizing the drying capacity as well as possible. In kiln drying of timber the changing of drying circumstances can in some cases save 50-150 FIM per 1 cbm of dried timber.

Price of forest chips decreasing

International Nuclear Information System (INIS)

Hakkila, P.

2001-01-01

Use of forest chips was studied in 1999 in the national Puuenergia (Wood Energy) research program. Wood combusting heating plants were questioned about are the main reasons restricting the increment of the use of forest chips. Heating plants, which did not use forest chips at all or which used less than 250 m 3 (625 bulk- m 3 ) in 1999 were excluded. The main restrictions for additional use of forest chips were: too high price of forest chips; lack of suppliers and/or uncertainty of deliveries; technical problems of reception and processing of forest chips; insufficiency of boiler output especially in winter; and unsatisfactory quality of chips. The price of forest chips becomes relatively high because wood biomass used for production of forest chips has to be collected from wide area. Heavy equipment has to be used even though small fragments of wood are processed, which increases the price of chips. It is essential for forest chips that the costs can be pressed down because competition with fossil fuels, peat and industrial wood residues is hard. Low market price leads to the situation in which forest owner gets no price of the raw material, the entrepreneurs operate at the limit of profitability and renovation of machinery is difficult, and forest chips suppliers have to sell the chips at prime costs. Price of forest chips has decreased significantly during the past decade. Nominal price of forest chips is now lower than two decades ago. The real price of chips has decreased even more than the nominal price, 35% during the past decade and 20% during the last five years. Chips, made of small diameter wood, are expensive because the price includes the felling costs and harvesting is carried out at thinning lots. Price is especially high if chips are made of delimbed small diameter wood due to increased the work and reduced amount of chips. The price of logging residue chips is most profitable because cutting does not cause additional costs. Recovery of chips is

How Might Industry Governance Be Broadened To Include Nonproliferation

International Nuclear Information System (INIS)

Hund, Gretchen; Seward, Amy M.

2009-01-01

Broadening industry governance to support nonproliferation could provide significant new leverage in preventing the spread/diversion of nuclear, radiological, or dual-use material or technology that could be used in making a nuclear or radiological weapon. Industry is defined broadly to include (1) the nuclear industry, (2) dual-use industries, and (3) radioactive source manufacturers and selected radioactive source-user industries worldwide. This paper describes how industry can be an important first line of defense in detecting and thwarting proliferation, such as an illicit trade network or an insider theft case, by complementing and strengthening existing governmental efforts. For example, the dual-use industry can play a critical role by providing export, import, or security control information that would allow a government or the International Atomic Energy Agency (IAEA) to integrate this information with safeguards, export, import, and physical protection information it has to create a more complete picture of the potential for proliferation. Because industry is closest to users of the goods and technology that could be illicitly diverted throughout the supply chain, industry information can potentially be more timely and accurate than other sources of information. Industry is in an ideal position to help ensure that such illicit activities are detected. This role could be performed more effectively if companies worked together within a particular industry to promote nonproliferation by implementing an industry-wide self-regulation program. Performance measures could be used to ensure their materials and technologies are secure throughout the supply chain and that customers are legitimately using and/or maintaining oversight of these items. Nonproliferation is the overarching driver that industry needs to consider in adopting and implementing a self-regulation approach. A few foreign companies have begun such an approach to date; it is believed that

Synthesis report regarding the Forest Industry Program 1997-2002[Energy research]; Skogsindustriell energiforskning syntesrapport 1997-2002

2003-07-01

This synthesis report commissioned by the Thermal Engineering Research Institute (Varmeforsk) constitutes a summary of the Forest Industry Program up to and including turn of the year 2002/2003. According to the assignment the resulting reports of the program has specifically been related to the present and expected EU-directives and, as a base for interpretation, national rules and regulations of relevance to the programme. Also there is a discussion, from a broad perspective, of the value and usefulness of these reports as well as of how the resources should be spent and prioritised in a coming program. As a basis for the analysis a survey of the program directions and the aims descriptions for the periods 97-98, 99-00 and 01-02 has been carried out. Throughout the three periods there is a tendency going from specific areas of interest to a more general approach which in the last program period has resulted in program directions emphasizing utilization of energy, energy integration and coordination with industry and enterprises outside the forest industry where it applies. A survey of the relevant EU-directives has been carried out. A division was made between directives related to legislation overall, permits related to combustion, operation of combustion plants and landfilling of refuse. In total 26 reports have been summarized and evaluated. They include some, which, at the time of finishing the present report, had not yet been published. The overall result has been synthesized in a discussion covering contents, aims, fulfillment and value of the reports. The work have been structured and presented based on some main activity areas that have been possible to identify from the program directions and policy statements, they are: combustion efficiency, improved energy utilization and novel concepts. Some reports, which have not been possible to arrange under these headings and furthermore are difficult to associate with the main areas defined are covered under a

Post-harvest carbon emissions and sequestration in southern United States forest industries

Energy Technology Data Exchange (ETDEWEB)

Row, C.

1997-12-31

Whether the forest industries in the southern United States are net emitters or sequesters of carbon from the atmosphere depends on one`s viewpoint. In the short-term, the solid-wood industries-lumber, plywood, and panels--appear to sequester more carbon than is in the fossil fuels they use for processing. The paper industries, however, emit more carbon from fossil fuels than they sequester in the pulp and paper they manufacture. This viewpoint is quite limited. If one considers the life-cycles of solid-wood and paper products from seedlings to landfill, these industries sequester more carbon than they emit from burning fossil fuels. These industries also generate large amounts of energy by replacing fossil fuels with biofuels from processing residues, and wood-based products produce more energy from incineration and landfill gases. Use of the carbon in these biofuels in effect keeps fossil fuel carbon in the ground, considering that at least that amount of carbon would be emitted in producing alternative materials. Another way of looking the emission balances is that wood-based materials, pound for pound or use for use, are the most {open_quotes}carbon efficient{close_quotes} group of major industrial materials. 5 refs., 12 figs.

Potential of Basidiomycetous Fungi Isolated from Gunung Barus Forest North Sumatera in Decolorization of Wastewater of Textile Industry

Munir, E.; Priyani, N.; Suryanto, D.; Naimah, Z.

2017-03-01

A study of basidiomycetous fungi in decolorization of wastewater of textile industry has been started in our laboratory. The objective of this study was to obtain potential isolates and to examine their decolorization acitity. The fungi were isolated from local forest, Gunung Barus Forest, in North Sumatera and screened their ligninolytic activity qualitatively by bavendam method and the waste was obtained from local textile industry in Medan. Nineteen fungal isolates grew on plate agar medium containing 100% of waste supplemented with 2% glucose, and 6 of those exhibited good growth when glucose in the media was reduced to 1%. Surprisingly, these six potential isolates grew, although relatively at lower rate, when glucose was not included in the media. Meanwhile, there was no substantial decolorization of media could be observed on all plates cultures. Analyses of decolorization on liquid condition containing 25% of wastewater and no glucose showed that fungal grew at the bottom culture flask. All 6 isolates exhibited decolorization activity. Interestingly, mass of mycelia growth at the bottom absorbed dyes and dissolved suspended solid which was seemingly separated from very clean solution medium surrounding. These results indicated that the cultures utilized carbon source from waste and the extracellular matrixes produced by fungal isolates might involve in decolorization of textile wastewater.

Forest pathology in Hawaii

Science.gov (United States)

Gardner, D.E.

2003-01-01

Native Hawaiian forests are characterised by a high degree of endemism, including pathogens as well as their hosts. With the exceptions of koa (Acacia koa Gray), possibly maile (Alyxia oliviformis Gaud.), and, in the past, sandalwood (Santalum spp.), forest species are of little commercial value. On the other hand, these forests are immensely important from a cultural, ecological, and evolutionary standpoint. Forest disease research was lacking during the mid-twentieth century, but increased markedly with the recognition of ohia (Metrosideros polymorpha Gaud.) decline in the 1970s. Because many pathogens are themselves endemic, or are assumed to be, having evolved with their hosts, research emphasis in natural areas is on understanding host-parasite interactions and evolutionary influences, rather than disease control. Aside from management of native forests, attempts at establishing a commercial forest industry have included importation of several species of pine, Araucaria, and Eucalyptus as timber crops, and of numerous ornamentals. Diseases of these species have been introduced with their hosts. The attacking of native species by introduced pathogens is problematic - for example, Armillaria mellea (Vahl ex Fr.) Que??l. on koa and mamane (Sophora chrysophylla (Salisb.) Seem.). Much work remains to be done in both native and commercial aspects of Hawaiian forest pathology.

Full Text Available Model Forests are partnerships for shared decision-making to support social, environmental, and economic sustainability in forest management. Relationships among sustainable forest management partners are often strained, but the Prince Albert Model Forest (PAMF represents a process of effective stakeholder involvement, cooperative relationships, visionary planning, and regional landscape management. This article seeks to critically examine the history, drivers, accomplishments, and challenges associated with the PAMF. Four key phases are discussed, representing different funding levels, planning processes, research projects, and partners. Key drivers in the PAMF were funding, urgent issues, provincial responsibility, core of committed people, evolving governance, desire for a neutral organisation, role of protected areas, and potential for mutual benefits. The stakeholders involved in the Model Forest, including the forest industry and associated groups, protected areas, Aboriginal groups, local communities, governments, and research groups, were committed to the project, cooperated on many joint activities, provided significant staffing and financial resources, and gained many benefits to their own organisations. Challenges included declining funding, changing administrative structures, multiple partners, and rotating representatives. The PAMF process promoted consultative and integrated land resource management in the region, and demonstrated the positive results of cooperation between stakeholders interested in sustainable forest management.

Full Text Available Introduction: Petroleum hydrocarbons are widespread pollutant that enters to soil by some pathwayssuch as: Transportation of crude oil, conservation of oil compounds, crude oil spill and treatment process on refineries. Oil pollution has some ecological effect on soil that disturbed composition and diversity of microbial community. Also this pollution has some effects on microbial activity and enzymes of soil. Forests ecosystems may be polluted with petroleum hydrocarbons via different ways such as transportation and spill of crude oil from resource of petroleum storage. Industrial soil defined as the soils that located in industrial area such as petrochemical plant, mine, chemical factories and etc. These soils always contaminated to many pollutant such as: oil, diesel and heavy metals. These pollutants have some effects on the texture of the soil and microbial community. The aim of this research is to understand the effect of oil pollution on two different soils. Material and Methods: In order to evaluate the effect of crude oil on soil microbial community, two different soil samples were collected from industrial and forest soils. Six microcosms were designed in this experiment. Indeed each soil sample examined inthree microcosms asunpolluted microcosm, polluted microcosm, and polluted microcosm with nutrient supply of Nitrogen and PhosphorusSome factors were assayed in each microcosm during 120 days of experiment. The included study factors were: total heterotrophic bacteria, total crude oil degrading bacteria, dehydrogenase enzyme and crude oil biodegradation. For enumeration of heterotrophic bacteria nutrient agar medium was used. In this method serial dilutions were done from each soil and spread on nutrient agar medium then different colonies were counted. For enumeration of degrading bacteria Bushnel-Hass (BH medium were used. The composition of this medium was (g/lit: 1 gr KH2PO4, 1gr K2HPO4, 0.2 gr MgSO4.7H2O, 0.02 gr CaCl2, 1 gr NH4

This report compiles operating experience from eight forest industrial boilers converted to BFB technology. The conversion has in all cases been driven by the need by increasing the solid fuel capacity and an increased interest in electricity generation as rising electricity prices. Conversion of an existing boiler has proven to be a cost effective alternative which by responding plant owners is described as being equivalent to new construction in terms of reliability. The studied boilers exhibit run times of between 350 and more than 360 days per year. The choice of BFB is justified by the boiler type's good opportunities to burn wet fuel and its ability to cope with rapid load changes. In terms of emission it turns out that these boilers, as compared with NO{sub x}-register, are somewhat better than average for the forest industrial boilers and slightly worse than the average for boilers in total. Analysis of data of studied boilers shows that there is a clear correlation between high fire load and high emissions. Construction owners report a few cases of corrosion and erosion. Sintering and bed agglomeration occur, but is not a major problem. Most problem have been fuel related

The focal question of the study was to increase the understanding of electronic business in the forest and energy sectors. To recognize trends, business potential and best ideas in this field, we have used interviews, the Delphi method, Scenario method, Idea session methods, analysis of alliances, Clustering and Portfolio management tools. One purpose of this study is to combine 'top down' approaches in describing alternative future views in electronic business field and 'bottom up' approaches to situate business ideas into different scenarios and contexts. Electrification of business processes can be divided into the electrification of organizations' internal processes, processes between organizations, and electrification of customer interface. According to results organizations are already quite advanced in optimizing internal processes and the next phase is to optimize processes between different actors, which also provide opportunities for new kind of services and products. At the customer interface value orientation instead of an 'IT as your service' orientation is one of the main driving forces. Although the motivation for e-business projects primarily come now from cost savings and productivity improvements, opportunities for new business innovations increase significance in the future. Most important technological drivers of change include common global standards, interoperability, service oriented architecture (SOA), Web Services, radio frequency identification (RFID) and IT outsourcing. Business logic has changed toward a more networked action with a customer value orientation. An overall view resulting from the study is that the industries' opportunity spectrum for digital business development is relatively wide. Key questions in digitization strategies of industries include the division between industry core processes and support processes and in the outsourcing strategies of these different processes.

Slamet, B.; Agustiarni, Y.; Hidayati; Basyuni, M.

2018-03-01

Urban forest has many functions mainly on improving the quality of the urban environment. One of the functions is to increase pH and reduce dangerous chemical content. The aim of the research is to find out the role of vegetation density of urban forest around the industrial area in reducing the acid rain. The condition of land cover was classified into four classes which are dense, medium, sparse and open area. The water of the throughfall and stemflow was taken from each type of land cover except in the open area. Parameters measured in this study are water acidity (pH), anion content (SO4 2- and NO3 -), cation content (Ca2+, Mg2+, and NH4 +) and electrical conductivity (EC). The results indicated that urban forest vegetation was able to increase the pH of rain water from 5.42 which is in an open area without vegetation to be 7.13 and 7.32 in dense and moderate vegetation cover by throughfall mechanism, respectively. Rain water acidity also decreased through stemflow mechanism with a pH ranged from 5.92 - 6.43. Urban forest vegetation decreased sulfate content (SO42-) from 528.67 mg/l in open area to 44 - 118 mg/l by throughfall mechanism and ranged from 90 to 366.67 mg/l through stemflow mechanism. Urban forest vegetation significantly decreased the rainwater nitrate content from 27 mg/l to 0.03 - 0.70 mg/l through the mechanism of throughfall and between 1.53 - 8.82 mg/l through the stemflow mechanism. Urban forest vegetation also increased the concentration of cations (NH4+, Ca2+, Mg2+, Na+) compared with open areas. Urban forest vegetation showed increased the electrical conductivity (EC) from 208.12 μmhos/cm to 344.67 - 902.17 μmhos/cm through the through fall mechanism and 937.67 - 1058.70 μmhos/cm through the stemflow mechanism. The study suggested that urban forests play a significant role in reducing rainwater acidity and improving the quality of rainwater that reached the soil surface.

Broadening Industry Governance to Include Nonproliferation

Hund, Gretchen; Seward, Amy M.

2008-11-11

As industry is the first line of defense in detecting and thwarting illicit trade networks, the engagement of the private sector is critical to any government effort to strengthen existing mechanisms to protect goods and services throughout the supply chain. This study builds on previous PNNL work to continue to evaluate means for greater industry engagement to complement and strengthen existing governmental efforts to detect and stem the trade of illicit goods and to protect and secure goods that could be used in making a weapon of mass destruction. Specifically, the study evaluates the concept of Industry Self Regulation, defined as a systematic voluntary program undertaken by an industry or by individual companies to anticipate, implement, supplement, or substitute for regulatory requirements in a given field, generally through the adoption of best practices. Through a series of interviews with companies with a past history of non-compliance, trade associations and NGOs, the authors identify gaps in the existing regulatory infrastructure, drivers for a self regulation approach and the form such an approach might take, as well as obstacles to be overcome. The authors conclude that it is at the intersection of industry, government, and security that—through collaborative means—the effectiveness of the international nonproliferation system—can be most effectively strengthened to the mutual benefit of both government and the private sector. Industry has a critical stake in the success of this regime, and has the potential to act as an integrating force that brings together the existing mechanisms of the global nonproliferation regime: export controls, physical protection, and safeguards. The authors conclude that industry compliance is not enough; rather, nonproliferation must become a central tenant of a company’s corporate culture and be viewed as an integral component of corporate social responsibility (CSR).

Beer, G.; Sobinkovic, B.

2004-01-01

A decision to be made by Director of state-owned company Lesy SR Banska Bystrica (Slovak Forests), Karol Vins and the company management will influence the development of Slovak wood-processing industry for many years to come. He has to decide who will belong to an elite group of Slovak wood-processing companies. Those will be given a strategic advantage compared to their competitors: middle-term contracts for deliveries of wood from state forests. Majority of local wood-processing companies do not have longer than quarterly contracts signed for deliveries of wood from state-owned forests. And so they would like to introduce new business rules for Lesy SR by the end of this year. But K. Vins claims that the decision about key customers has to be made by Ministries of Economy and Land Management. Lesy SR cut about 50 percent of all wood cut in Slovakia and are therefore the most important supplier of this material on the market. And so all the major companies on the market focusing on immediate processing of wood are interested in it. . In general their prices are a few percent below the level as the volumes they offer are also lower. And so consumers complain mainly about high prices and the fact that they are not allowed to sign long-term contracts for wood deliveries. They also complain that the management of Lesy SR is not able to set realistic wood prices as it does not know the actual costs of wood and cutting price per 1 cubic meter of wood. Lesy SR are facing a major transformation. The management asked for a change organisation of the company, concentration of sale of wood, decreasing the number of staff by 3 600 people. The sale of redundant property should earn the company 1,4 bn Sk (35.03 mn Eur). The final decision on how the organization and economy of the company will change has to be made by the cabinet

Influence of air pollution on the northern forest vegetation

Energy Technology Data Exchange (ETDEWEB)

Huttunen, S

1976-01-01

The forest vegetation has been the object of air pollution research in the vicinities of several industrial processes in Finland; the main object has been the town of Oulu (65/sup 0/ N) and the area near a chemical processing plant there. The starting point was the altered forest ecosystem; on the basis of the changes in the vegetation attempts were made to seek the causes of the changes, that is, to analyze what gives cause to so-called industrial vegetation. The main objects of the investigation are the typical species of prevailing type of forest: Pinus sylvestris, Vaccinium vitis-idaea, Empetrum nigrum coll., mosses and lichens. The nutrition balance of the altering forest ecosystem has been studied for several years, including the studies of the hydrogen ion conditions of rainfall, snow and humus layer, the nutrients in plants, particularly in dwarf shrubs and pine needles, and changes in the soil.

Leaf and soil samples were collected in the conservation unit Parque Estadual da Serra do Mar (PESM) nearby the industrial complex of Cubatao, Sao Paulo State, Brazil, and analyzed for chemical elements by instrumental neutron activation analysis. Results were compared to background values obtained in the Parque Estadual Carlos Botelho (PECB). The higher As, Fe, Hg and Zn mass fractions in the tree leaves of PESM indicated anthropogenic influence on this conservation unit. (author)

Fertilization in Sweden and Finland is currently practiced by extensive fertilization regimens where nitrogen fertilizers are applied once, or up to three times, during a rotation period, mainly in mature forest. This type of fertilization...... gives, in most cases, a small and transient effect on the environment as well as a high rate of return to the forest owner with low-economic risk.

We review patterns and processes important for biodiversity in the Fennoscandian boreal forest, describe man's past and present impact and outline a strategy for conservation. Natural disturbances, particularly forest fire and gap formation, create much of the structural and functional diversity in forest ecosystems. Several boreal plants and animals are adapted to fire regimes. In contrast, many organisms (epiphytic lichens, fungi, invertebrates) require stable conditions with long continuity in canopy cover. The highly mechanized and efficient Fennoscandian forest industry has developed during the last century. The result is that most natural forest has been lost and that several hundreds of species, mainly cryptograms and invertebrates, are threatened. The forestry is now in a transition from exploitation to sustainable production and has recently incorporated some measures to protect the environment. Programmes for maintaining biodiversity in the boreal forest should include at least three parts. First, the system of forest reserves must be significantly improved through protection of large representative ecosystems and key biotopes that host threatened species. Second, we must restore ecosystem properties that have been lost or altered. Natural disturbance regimes must be allowed to operate or be imitated, for example by artificial fire management. Stand-level management should particularly increase the amount of coarse woody debris, the number of old deciduous trees and large, old conifers, by using partial cutting. Third, natural variation should also be mimicked at the landscape level, for example, by reducing fragmentation and increasing links between landscape elements. Long-term experiments are required to evaluate the success of different management methods in maintaining biodiversity in the boreal forest. (au) 260 refs

Consequences of long-term severe industrial pollution for aboveground carbon and nitrogen pools in northern taiga forests at local and regional scales.

Science.gov (United States)

Manninen, Sirkku; Zverev, Vitali; Bergman, Igor; Kozlov, Mikhail V

2015-12-01

Boreal coniferous forests act as an important sink for atmospheric carbon dioxide. The overall tree carbon (C) sink in the forests of Europe has increased during the past decades, especially due to management and elevated nitrogen (N) deposition; however, industrial atmospheric pollution, primarily sulphur dioxide and heavy metals, still negatively affect forest biomass production at different spatial scales. We report local and regional changes in forest aboveground biomass, C and N concentrations in plant tissues, and C and N pools caused by long-term atmospheric emissions from a large point source, the nickel-copper smelter in Monchegorsk, in north-western Russia. An increase in pollution load (assessed as Cu concentration in forest litter) caused C to increase in foliage but C remained unchanged in wood, while N decreased in foliage and increased in wood, demonstrating strong effects of pollution on resource translocation between green and woody tissues. The aboveground C and N pools were primarily governed by plant biomass, which strongly decreased with an increase in pollution load. In our study sites (located 1.6-39.7 km from the smelter) living aboveground plant biomass was 76 to 4888 gm(-2), and C and N pools ranged 35-2333 g C m(-2) and 0.5-35.1 g N m(-2), respectively. We estimate that the aboveground plant biomass is reduced due to chronic exposure to industrial air pollution over an area of about 107,200 km2, and the total (aboveground and belowground) loss of phytomass C stock amounts to 4.24×10(13) g C. Our results emphasize the need to account for the overall impact of industrial polluters on ecosystem C and N pools when assessing the C and N dynamics in northern boreal forests because of the marked long-term negative effects of their emissions on structure and productivity of plant communities.

Integrating strategic environmental assessment with industry planning: a case study of the Pasquai-Porcupine forest management plan, Saskatchewan, Canada.

Science.gov (United States)

Noble, Bram F

2004-03-01

Strategic environmental assessment (SEA) is gaining widespread recognition as a tool for integrating environmental considerations in policy, plan, and program development and decision-making. Notwithstanding the potential of SEA to improve higher-order decision processes, there has been very little attention given to integrating SEA with industry planning practices. As a result, the benefits of SEA have yet to be fully realized among industrial proponents. That said, SEA practice is ongoing, albeit informally and often under a different label, and is proving to be a valuable tool for industry planning and decision-making. Based on a case study of the Pasquai-Porcupine forest management plan in Saskatchewan, Canada, this paper illustrates how an integrated approach to SEA can contribute to industry environmental decision-making and can enhance the quality and deliverability of industry plans.

Forest health in Canada, Atlantic Maritime ecozone 2003

Energy Technology Data Exchange (ETDEWEB)

Hurley, J.E.; Loo, J.; DesRochers, P.; Hirvonen, H.

2004-07-01

This paper describes the key forest health issues affecting Canada's Atlantic Maritime ecozone which includes 9 main forest types known collectively as the Acadian Forest. In order to protect and conserve biological diversity, the Canadian Council of Forest Ministers adopted national criteria to measure sustainable forest management. This report describes the Acadian Forest landscape conditions, pre-industrial ecological influences, current ecological influences, and the impact of invasive alien insects and diseases on the diversity of tree species. Spruce trees in the Atlantic Maritime ecozone are threatened by the brown spruce longhorn beetle and pine trees are threatened by a pine shoot beetle recently introduced to North America from Asia. Diseases are also attacking the butternut, beech and dutch trees. The impact of land use practices such as forest harvesting on forest structure and composition was also addressed along with the impact of air pollution and climate change. It was noted that there is a direct relationship between deteriorating air quality and decline in mountain paper birch. Some of the anticipated impacts from climate change include a greater incidence of vector borne diseases resulting from the migration of new insect species in a warmer Canadian climate. An increase in extreme weather events such as ice storms may also weaken trees. refs., tabs., figs.

Quantifying the environmental impact of an integrated human/industrial-natural system using life cycle assessment; a case study on a forest and wood processing chain.

Science.gov (United States)

Schaubroeck, Thomas; Alvarenga, Rodrigo A F; Verheyen, Kris; Muys, Bart; Dewulf, Jo

2013-01-01

Life Cycle Assessment (LCA) is a tool to assess the environmental sustainability of a product; it quantifies the environmental impact of a product's life cycle. In conventional LCAs, the boundaries of a product's life cycle are limited to the human/industrial system, the technosphere. Ecosystems, which provide resources to and take up emissions from the technosphere, are not included in those boundaries. However, similar to the technosphere, ecosystems also have an impact on their (surrounding) environment through their resource usage (e.g., nutrients) and emissions (e.g., CH4). We therefore propose a LCA framework to assess the impact of integrated Techno-Ecological Systems (TES), comprising relevant ecosystems and the technosphere. In our framework, ecosystems are accounted for in the same manner as technosphere compartments. Also, the remediating effect of uptake of pollutants, an ecosystem service, is considered. A case study was performed on a TES of sawn timber production encompassing wood growth in an intensively managed forest ecosystem and further industrial processing. Results show that the managed forest accounted for almost all resource usage and biodiversity loss through land occupation but also for a remediating effect on human health, mostly via capture of airborne fine particles. These findings illustrate the potential relevance of including ecosystems in the product's life cycle of a LCA, though further research is needed to better quantify the environmental impact of TES.

Consequences of increasing bioenergy demand on wood and forests: An application of the Global Forest Products Model

Science.gov (United States)

Buongiorno, J.; Raunikar, R.; Zhu, S.

2011-01-01

The Global Forest Products Model (GFPM) was applied to project the consequences for the global forest sector of doubling the rate of growth of bioenergy demand relative to a base scenario, other drivers being maintained constant. The results showed that this would lead to the convergence of the price of fuelwood and industrial roundwood, raising the price of industrial roundwood by nearly 30% in 2030. The price of sawnwood and panels would be 15% higher. The price of paper would be 3% higher. Concurrently, the demand for all manufactured wood products would be lower in all countries, but the production would rise in countries with competitive advantage. The global value added in wood processing industries would be 1% lower in 2030. The forest stock would be 2% lower for the world and 4% lower for Asia. These effects varied substantially by country. ?? 2011 Department of Forest Economics, SLU Ume??, Sweden.

State forest timber sales in 2006

International Nuclear Information System (INIS)

Office National des Forets

2007-01-01

For the first time since the 1999 storms, forest owners have experienced a favourable market. The combination of buoyant demand for both industrial round-wood and timber and consolidation of supply led to a significant increase in prices. With a logging volume of 15 million m 3 (standing timber equivalent), state forest timber supply has remained at a high level, slightly above that of 1999. The improved business cycle situation has pushed prices up, including for beech for which rates had stagnated for some time. However, in spite of the 15% rise compared to 2005, the average per cubic metre price sold by the ONF (31.20 euros), all categories of timber and all state forests taken together, remains well below the average for the 1996-1999 period (37.80 euros). While unsold stocks have fallen considerably, the ONF has sought to facilitate access to products by industry by modernising its sales methods in line with the new 2005 legislative and regulatory provisions. Greater flexibility in the rules applicable to privately negotiated spot sales and supply contracts should over time contribute to stabilizing and reducing the accessory costs of supply. The changes implemented over the last decade in favour of private sales, which now account for nearly 40% of volumes sold, should continue in the future. Of those volumes, 20% were sold under supply contracts, a proportion that is rising sharply. These contracts covered more than one million m 3 in 2006, encouraging the ONF to adopt a new sales scheme and establish structures for consultations with both forest municipalities and the downstream component of the industry.

Heavy metal pollution and forest health in the Ukrainian Carpathians

International Nuclear Information System (INIS)

Shparyk, Y.S.; Parpan, V.I.

2004-01-01

The Ukrainian Carpathians are characterized by high air pollution caused by emissions from numerous industries. We have been monitoring the state of forests in this region since 1989. The highest levels of tree defoliation (>30%) are found close to industrial emission sources and in the upper mountain forests of the Ivano-Frankivsk and Chernivtsi regions. This is caused by a combination of strong anthropogenic influences (pollution, illegal uses, recreation) as well as poor site and climatic conditions. In the Ivano-Frankivsk region, Cd and Mo accumulate in forest soils; Cr, Mo and Zn soil concentrations are higher than their limit levels; and Pb concentrations exceed toxic levels close to industrial areas (10% of the region territory). Local background levels of heavy metals are greatly exceeded in snow close to industrial regions. Analysis of correlation matrices shows that the chemical elements Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, V and Zn occur at pollution levels in natural ecosystems in the Ukrainian Carpathians. Maximum concentrations of toxic elements occur in the oak forest zone; the most industrially developed area of the region. Toxic heavy metals in the Ukrainian Carpathians forests enter with precipitation and dustfall, then become fixed in soil and accumulate in leaves, needles of vascular plants and mosses. Concentrations of these metals decrease with altitude: highest in the oak forests, less in beech, and lowest in the spruce forest zones. However, some chemical elements have the highest concentrations in spruce forests; V in needles, As in snow, and Ba and Al in soils. - Local industrial emissions of heavy metal pollution and the condition of Ukrainian Carpathians forests are examined

U.S. forests occupy approx.1/3 of total land area (approx. 304 million ha). Since 2000, a growing number of regionally evident forest disturbances have occurred due to abiotic and biotic agents. Regional forest disturbances can threaten human life and property, bio-diversity and water supplies. Timely regional forest disturbance monitoring products are needed to aid forest health management work. Near Real Time (NRT) twice daily MODIS NDVI data provide a means to monitor U.S. regional forest disturbances every 8 days. Since 2010, these NRT forest change products have been produced and posted on the US Forest Service ForWarn Early Warning System for Forest Threats.

This paper explores the development of the urban forest in East Jakarta. By 2030 Jakarta area has a target of 30% green area covering 19,845 hectares, including urban forest covering an area of 4,631 hectares. In 2015, the city forest is only 646 hectares, while the city requires 3,985 hectares of new land Urban forest growth from year to year showed a marked decrease with increasing land area awoke to commercial functions, environmental conditions encourage the development of the city to become unsustainable. This research aims to support sustainable urban development and ecological balance through the revitalization of green areas and urban development. Analytical methods for urban forest area is calculated based on the amount of CO2 that comes from people, vehicles, and industrial. Urban spatial analysis based on satellite image data, using a GIS program is an analysis tool to determine the distribution and growth patterns of green areas. This paper uses a dynamic system model to simulate the conditions of the region against intervention to be performed on potential areas for development of urban forests. The result is a model urban forest area is integrated with a social and economic function to encourage the development of sustainable cities.

An exploratory assessment of the attitudes of Chinese wood products manufacturers towards forest certification.

Science.gov (United States)

Chen, Juan; Innes, John L; Kozak, Robert A

2011-11-01

Interviews with Chinese forest products manufacturers were conducted to explore their attitudes towards forest certification and related issues. Participants comprised owners, CEOs, and managers in 20 Chinese wood products companies, including producers of furniture, doors, flooring, and various engineered wood products. The interviews were used to analyze the extent to which participants were considering adopting forest certification and what might motivate such a decision. This was done by assessing their awareness and knowledge of certification. The results indicated that participants' understanding of forest certification was extremely low, despite major efforts in China to raise awareness of the issue. Potential economic benefits were the most frequently cited reason to adopt certification, including gaining or maintaining competitive advantage over their industry counterparts, improved access to both domestic and export markets, better customer recognition, and enhanced corporate responsibility practices. Some interviewees (3 out of 20) considered that certification would become a mandatory requirement or industry standard, and that this would be the only viable motivation for certification given that the financial benefits were potentially limited. According to the participants, the main differences between certified and uncertified wood products operations related to improved market access and public image. Interviewees felt that cooperation between and support from governments and the forest industry would enable the enhanced awareness of certification amongst manufacturers and the general public. This, in turn, could serve to stimulate demand for certified products. Copyright © 2011 Elsevier Ltd. All rights reserved.

The wood industry in Atlantic Canada: A focus on value-added

International Nuclear Information System (INIS)

1998-11-01

This report prepared by the Atlantic Canada Opportunities Agency in consultation with the four Atlantic provinces focuses on the value-added aspects of the wood products industry in Atlantic Canada. It also examines the state of the resource, the state of the industry, productivity and economic benefits, products and markets, trade and regulations, and needs, challenges and targets. The analysis was undertaken to determine the possibility of further utilization of forest resources in the region for value-added products, and to assess the possibilities for the wood products industry of Atlantic Canada exploring world markets for its products. The inventory of resources found 1.4 billion cubic meter of wood-growing productive forest land in the region, with softwoods accounting for 76 per cent of the forests. Concern was expressed about forest stands at regeneration levels. Total Annual Allowable Cut (AAC) for the Atlantic Provinces in 1995 was almost 20 million cubic meter, approximately 10 per cent of the national total. Although total harvests are below the AAC for the region, softwood harvesting in 1994 and in 1995 was well above the AAC. The analysis concluded that given the current level of harvesting, sustained growth in Atlantic Canada's wood industries will have to rely on access to external fibre sources and better use of the existing fibre source. At the same time, since many value-added manufacturers in the region rely on imported wood resources, the health of the value-added wood industry does not appear to be completely dependent on the sustainability of forest resources in the Atlantic region. Part Two of the report provides an economic profile of the industry, including brief reviews on employment, wages and salaries, exports and imports, transportation, education and training, research and technology and marketing. refs., tabs

Mudumalai is biologically rich with a wealth of plant and animal life. Increasing human numbers and current patterns of non-timber forest product, fodder and fuelwood extraction threaten the integrity of the ecosystem. Change in management of the protected areas that include the Mudumalai region is needed. In particular, policies relating to grazing and basic energy requirements need to be reexamined. At the same time, mechanisms must be developed to increase rural incomes using means other than exploitation of natural resources. 7 refs., 3 tabs

Using Goal-Programming to Model the Effect of Stakeholder Determined Policy and Industry Changes on the Future Management of and Ecosystem Services Provision by Ireland’s Western Peatland Forests

Directory of Open Access Journals (Sweden)

Edwin Corrigan

2016-12-01

Full Text Available Recent studies have highlighted land-use conflicts between stakeholder groups in Ireland. Some of these conflicts can be attributed to European directives, designed with sustainable forest management principles in mind, but imposing incoherencies for land-owners and stakeholders at the local level. This study, using Ireland’s Western Peatland forests as a case study area, focused on the development and implementation of a goal programming model capable of analysing the long term impact of policy and industry changes at the landscape level. The model captures the essential aspects of the changes identified by local level stakeholders as influencing forest management in Ireland and determines the future impact of these changes on ecosystem services provisions. Initially, a business as usual potential future is generated. This is used as a baseline against which to compare the impact of industry and policy changes. The model output indicated that the current forest composition is only really suited to satisfy a single, financial objective for forest management. The goal programming model analysed multiple objectives simultaneously and the results indicated that the stakeholders’ desired ecosystem service provisions in the future will be more closely met by diversifying the forest estate and/or by changing to an alternative, non-forest land-use on less productive areas.

Attraction of Foreign Investments in the Sphere of Economic Development of the Forest Resource Potential and Woodworking Industry: Institutional and Territorial Preconditions

Dzyubenko Oleksandr M.

2017-12-01

Full Text Available It has been found that it is possible to overcome the existing investment deficit in the forestry and woodworking segments of the forestry sector of the national economy on the basis of expanding the list of forms, methods and sources of attracting foreign investments into the sphere of economic development of the forest resource potential and wood processing. There revealed main trends in the dynamics of expenses for the maintenance and operation of equipment, as well as the maintenance and operation of forest roads across the regional forestry and hunting management departments. The priorities of improving the institutional environment for attracting foreign investments in the sphere of economic development of the forest resource potential and woodworking industry are substantiated based on implementing by state forest enterprises joint projects with foreign partners, as well as projects within the framework of public-private partnership agreements.

New ecology, global change, and forest politics

International Nuclear Information System (INIS)

Sampson, N.

1993-01-01

Ecosystems constantly change. Some changes are caused by natural conditions that evolve at a very slow pace including climate change, species evolution and migration, and soil formation. Forests don't always respond to gradual changes in gradual ways, though gradual change may be hidden for years within the normal variation in the ecosystem. The industrial age has resulted in a rapid and continuing buildup of atmospheric gases such as carbon dioxide, methane, and chlorofluorocarbons which trap heat in the greenhouse effect. Industrial processes also emit oxides of nitrogen and sulfur that change atmospheric chemistry and alter the nutrient input into ecosystems. Natural forests face a hard time adjusting to a rate of climatic change that is 3 to 10 times faster than species can migrate and that increases the occurrence of major windstorms. In the forest ecosystem where trees are removed or destroyed under rapid climatic change, conditions may not return to their original state, even if we try to restore it. When the ecosystem changes faster than the bureaucracy of the management agency, a serious problem exists. New understandings of ecology and global change may force new ways of thinking in these situations

Full Text Available Baseline entomological information should be collected before the implementation of industrial projects in malaria endemic areas. This allows for subsequent monitoring and evaluation of the project impact on malaria vectors. This study aimed at assessing the vectorial system and malaria transmission in two ecologically different villages of the South-Cameroon forest bloc targeted for the creation of an agro-industrial complex. For four consecutive seasons in 2013, adult mosquitoes were captured using Human Landing Catch in NDELLE village (located along a main road in a degraded forest with many fish ponds and KOMBO village (located 5km far from the main road in a darker forest and crossed by the Mvobo River. Morpho-taxonomic techniques were used alongside molecular techniques for the identification of mosquito species. ELISA test was used for the detection of circumsporozoite protein antigen of Plasmodium falciparum. Mosquito biting rate was higher in NDELLE than in KOMBO (28.18 versus 17.34 bites per person per night. Mosquitoes had a strong tendency to endophagy both in NDELLE (73.57% and KOMBO (70.21%. Three anophelines species were identified; An. gambiae, An. funestus s.s and An. moucheti s.s.. An. gambiae and An. funestus s.s. represented the bulk of aggressive mosquitoes in NDELLE (n=10,891; 96.62%. An. gambiae was responsible for 62.6% and 77.72% of malaria transmission in KOMBO and NDELLE respectively. Mean entomological inoculation rate recorded in KOMBO and NDELLE were 4.82 and 2.02 infective bites per person per night respectively. Vector control was mainly based on the use of long-lasting insecticidal nets and indoor residual spraying. The degraded forest environment added to the presence of fishponds resulted in the increase of aggressive mosquito density but not of malaria transmission. The managers should use these data for monitoring and evaluation of the impact of their project; malaria control strategies should be included in

Full Text Available The purpose of this study is to provide an overview of the development of community forests in South Kalimantan and information about the properties and benefits of community forest timber, the hopes community forests timber can be developed into a source of raw materials of natural forest wood substitute that can support the development of the wood processing industry in South Kalimantan. The result showed that Community forest proved to be very useful both for the owner, the community and the environment as well as for the government especially in order to meet the timber supply for local. Until the year 2011 the community forest area that was developed by the government in South Kalimantan has reached 2,895 ha, and the most widely are the Tanah Laut district covering 935 ha. The wood species that developed is sengon, jati, mahoni, karet, petai, akasia, galam, kemiri. The properties of the wood need to be understood and known before the relevant timber used both as a building material or as raw material for the industry, because these properties are basically determining the quality of wood products that will be produced. Technically private community forest wood can be used for building materials, components boat/ship and industrial raw materials.

Polands once considerable forest resource suffered destruction during World War II and is now a victim of the legacy of past forest practices, the toxic effects of industrial pollution, and the urgent needs of its people today. Polish forest are threatened by a variety of abiotic, biotic and anthropogenic factors. Extremes of climate and declining groundwater tables add to the problem. Pollution is the most serious problem, particularly air pollution. Much of the air pollution in Poland is attributable to mining and burning high-sulfur coal. Besides describing the causes of the forest decline, this article discusses solutions

Forest health in Canada, Montane cordillera ecozone 2003

2004-07-01

This paper describes the key forest health issues affecting the 6 main forest types in Canada's Montane Cordillera ecozone in the central interior of British Columbia and the Alberta Foothills. In order to protect and conserve biological diversity, the Canadian Council of Forest Ministers adopted national criteria to measure sustainable forest management. This report describes the Montane Cordillera landscape conditions, pre-industrial ecological influences, current ecological influences, and the impact of invasive alien insects and diseases on the diversity of tree species. Pine forests in the Montane Cordillera ecozone are threatened by the mountain pine beetle. Fire suppression has also resulted in ecological changes to forests in the Montane Cordillera, including an increase in Douglas-firs, gradual replacement of Lodgepole pine forests, and reduced health of Ponderosa pine ecosystems. Alien insects are being monitored by provincial forestry agencies through annual surveys. They are also being controlled through localized treatment programs. The impact of land use practices such as forest harvesting on forest structure and composition was also addressed. It was noted that the unrestricted movement of wood and forestry products also increases the threat of invasive alien diseases and insects. The trees in this ecozone have not been damaged by air pollution. refs., tabs., figs.

Near surface air temperature and rainfall are major weather factors affecting forest insect dynamics. The recent developments in remote sensing retrieval and geographic information system spatial analysis techniques enable the utilization of weather factors to significantly enhance forest pest forecasting and warning systems. The current study focused on building forest pest digital data structures as a platform of correlation analysis between weather conditions and forest pest dynamics for better pest forecasting and warning systems using the new technologies. The study dataset contained 3 353 425 small polygons with 174 defined attributes covering 95 counties of Guangxi province of China currently registering 292 forest pest species. Field data acquisition and information transfer systems were established with four software licences that provided 15-fold improvement compared to the systems currently used in China. Nine technical specifications were established including codes of forest districts, pest species and host tree species, and standard practices of forest pest monitoring and information management. Attributes can easily be searched using ArcGIS9.3 and/or the free QGIS2.16 software. Small polygons with pest relevant attributes are a new tool of precision farming and detailed forest insect pest management that are technologically advanced. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

The potential for wood fired energy production in the UK is significant. Large scale developments are currently underway which could utilise over 100,000 green tonnes of forest residues. The fuel supply chain is likely to be complicated and there are perceived risks in its organisation and security. This report sets out to address some of these perceived risks and suggest suitable measures to reduce it. Six areas of the fuel supply chain have been studied, namely; Extraction, Comminution, Transport, Assessment and payment of wood fuel; Environmental impact; Nutrient recycling (ash disposal).

Full Text Available Tourism appeal includes natural places like beaches, eco-parks, lakes, valleys, rivers, islands etc., archeological sites, historic mosques and monuments, resorts, picnic spots, forest and wildlife. Bangladesh is a riverine country having attractive panoramic beauty. There are hills, valley, canals, lake, eco-park and mangrove forests, rivers, so many islands and the longest beach in the world. In this country, the scope of nature based tourism, resource based tourism, culture based tourism and eco-tourism is quite evident. Bangladesh is trying hard to develop its tourism industry. Therefore the whole situation deserves to be seen from right perspectives. Role of government is positive since the last twenty years both private and public organizations have come forwarded to attract the local and foreign tourists. The cracks of problem could not identify accurately because of the paucity number of researches and investigations in our country. Developed and organized tourism industry could change the economic condition and contribute a big share in the GDP of Bangladesh. This study will impede the opportunities of developing tourism industry in the light of existing resources.

Tropical Forest Gain and Interactions amongst Agents of Forest Change

Directory of Open Access Journals (Sweden)

Sean Sloan

2016-02-01

Full Text Available The tropical deforestation literature advocates multi-agent enquiry in recognition that key dynamics arise from inter-agent interactions. Studies of tropical forest-cover gain have lagged in this respect. This article explores the roles and key aspects of interactions shaping natural forest regeneration and active reforestation in Eastern Panama since 1990. It employs household surveys of agricultural landholders, interviews with community forest-restoration organisations, archival analysis of plantation reforestation interests, satellite image analysis of forest-cover change, and the consideration of State reforestation policies. Forest-cover gain reflected a convergence of interests and land-use trends amongst agents. Low social and economic costs of sustained interaction and organisation enabled extensive forest-cover gain, but low transaction costs did not. Corporate plantation reforestation rose to the fore of regional forest-cover gain via opportunistic land sales by ranchers and economic subsidies indicative of a State preference for autonomous, self-organising forest-cover gain. This reforestation follows a recent history of neoliberal frontier development in which State-backed loggers and ranchers similarly displaced agriculturalists. Community institutions, long neglected by the State, struggled to coordinate landholders and so effected far less forest-cover gain. National and international commitments to tropical forest restoration risk being similarly characterised as ineffective by a predominance of industrial plantation reforestation without greater State support for community forest management.

Governance of private forests in Eastern and Central Europe: An analysis of forest harvesting and management rights

Full Text Available A property rights-based approach is proposed in the paper to underlinethe common characteristics of the forest property rights specificationin ten ECE countries, the specific patterns governing the harvesting of timber in private forestry and the role of the forest management planning in determining the content of the property rights. The analysis deals with the private forests of the individuals (non industrial ownership from ten countries, covering 7.3 million ha and producing yearly some 25 million timber. The study shows that the forest management rights in private forests belong to the State and that the withdrawal rights on timber, yet recognized in the forest management plans, are in reality strongly restricted from aneconomic viewpoint. The forest management planning is the key instrument of the current forest governance system, based on top-down, hierarchically imposed and enforced set of compulsory rules on timber harvesting. With few exceptions, the forest owners’ have little influence in the forest planning and harvesting. The rational and State-lead approach of the private forest management has serious implications not only on the economic content of the property rights, but also on the learning and adaptive capacity of private forestry to cope with current challenges such the climate change, the increased industry needs for wood as raw material, or the marketingof innovative non wood forest products and services. The study highlights that understanding and comparing the regime of the forest ownership require a special analysis of the economic rights attached to each forest attribute; and that the evolution towards more participatory decision-making in the local forest governance can not be accurately assessed in ECE region without a proper understanding of the forest management planning process.

Forest managers often seek to balance economic benefits from timber harvesting with maintenance of habitat for wildlife, ecosystem function, and human uses. Most research on the relationship between avian abundance and active timber management has been short-term, lasting one to two years, creating the need to investigate long-term avian responses and to identify harvest thresholds when a small change in habitat results in a disproportionate response in relative abundance and nest success. Our objectives were to identify trends in relative abundance and nest success and to identify landscape-scale disturbance thresholds for avian species and habitat guilds in response to a variety of harvest treatments (clear-cuts, heavy and light partial harvests) over 14 years. We conducted point counts and monitored nests at an industrial forest in the central Appalachians of West Virginia during 1996–1998, 2001–2003, and 2007–2009. Early successional species increased in relative abundance across all three time periods, whereas interior-edge and forest-interior guilds peaked in relative abundance mid-study after which the forest-interior guild declined. Of 41 species with >10 detections, four (10%) declined significantly, 13 (32%) increased significantly (only three species among all periods), and 9 (22%) peaked in abundance mid-study (over the entire study period, four species had no significant change in abundance, four declined, and one increased). Based on piecewise linear models, forest-interior and interior-edge guilds’ relative abundance harvest thresholds were 28% total harvests (all harvests combined), 10% clear-cut harvests, and 18% light partial harvests, after which abundances declined. Harvest thresholds for the early successional guild were 42% total harvests, 11% clear-cut harvest, and 10% light partial harvests, and relative abundances increased after surpassing thresholds albeit at a reduced rate of increase after the clear-cut threshold.

Full Text Available The article discusses the construction process of forest certification in the Brazilian Amazon, emphasizing its importance for the new frame of lumber industry on that region. We sustain that one of the main results of the promotion of forest certification by the Forest Stewardship Council (FSC in Amazon was the constitution of an alliance between the environmentalist Non-Governmental Organizations, representative segments of forest business and members of the state bureaucracy for the promotion of lumber exploration based on forest management. In this perspective, the results produced by certification must be understood as part of a process of promotion of forest resources access policies, such as the approval of the Public Forests Management Law, and the creation of state entities destined to the promotion of lumber extraction on Amazon.

The project is part of a larger one promoted by the Italian Agency for Cellulose and Paper (E.N.C.C.) for an enhanced utilization of coppice forests in Italy. It concerns a Turkey oak (Quercus cerris) stand in Calabria. Stand characteristics and results of harvesting trials, first after-felling observations and technological investigations are reported. Results of an estimate of coppice forests biomass availability and of possibilities of expanding its use for energy are also given. Machinery damage to stumps was greatly reduced (1.7% of high-damaged stumps) by sprouts concentration by skyline. Sprouts weight appeared as a major factor affecting harvesting yield, Harvesting costs varied with different stand and terrain characteristics from 28,000 to 39,500 It. liras/t. Because of the high transport costs, the use of current coppice forests biomass is restricted within a short distance from the harvesting area. Industrial trials for fiberboard and paper pulp production from coppice whole-tree chipped biomass proved the possibility of its use in mixture with current raw material up to 75% for fiberboard production and up to 35-50% for corrugated paper pulp production. Relative expansion possibilities of coppice forest biomass consumption for energy were estimated, mainly localized in the central-northern Appennine and the Alpine areas. Given the permanence of a high convenience for its home consumption, wide development programs for coppice biomass industrial use for energy appear to be inconvenient. On the other hand, its use by local communities (schools, hospital, etc.) might be incentived in particular areas with high coppice production potential far from wood industries.

Whole-system carbon balance for a regional temperate forest in Northern Wisconsin, USA

Peckham, S. D.; Gower, S. T.

2010-12-01

The whole-system (biological + industrial) carbon (C) balance was estimated for the Chequamegon-Nicolet National Forest (CNNF), a temperate forest covering 600,000 ha in Northern Wisconsin, USA. The biological system was modeled using a spatially-explicit version of the ecosystem process model Biome-BGC. The industrial system was modeled using life cycle inventory (LCI) models for wood and paper products. Biome-BGC was used to estimate net primary production, net ecosystem production (NEP), and timber harvest (H) over the entire CNNF. The industrial carbon budget (Ci) was estimated by applying LCI models of CO2 emissions resulting from timber harvest and production of specific wood and paper products in the CNNF region. In 2009, simulated NEP of the CNNF averaged 3.0 tC/ha and H averaged 0.1 tC/ha. Despite model uncertainty, the CNNF region is likely a carbon sink (NEP - Ci > 0), even when CO2 emissions from timber harvest and production of wood and paper products are included in the calculation of the entire forest system C budget.

Tropical forest change is driven by demand in distant markets. Equally, investments in tropical forest landscapes by capital originating from distant emerging economies are on the rise. Understanding how forest outcomes vary by investment source is therefore becoming increasingly important. We empirically evaluate the relationship between investment source and deforestation from 2000 to 2010 in the Republic of Congo. A Congolese forestry code was implemented in 2000 to mitigate degradation of production forests by standardizing all logging in the country according to sustainable forest management (SFM) guidelines. Following the implementation of this law, the majority (73%) of Congo’s production forests were managed by European (40%) and Asian (33%) companies. European concessions had the highest rates of total and core deforestation, followed by Asian concessions, indicating that the fragmentation of intact forests in Congo is strongly associated with industrial logging fueled by foreign capital. European concession holders were also far more likely to comply with SFM policies, followed by Asian concessions, suggesting that compliance with Sustainable Forest Management policies may not mitigate degradation in tropical production forests. Further evaluation of the relationship between investment source, regulatory compliance, and outcomes in tropical countries is essential for effective conservation of tropical forest ecosystems.

-growing planting stock and shorter rotations, and weed, disease, and insect control, and increasing the interval between harvests or decreasing harvest intensity. Economic drivers will affect future carbon cycle of forests such as shifts in forest age class structure in response to markets, land-use changes such as urbanization, and forest type changes. Future changes in forestland objectives include the potential for bioenergy based on forestland resources, which is as large as 504 million acres of timberland and 91 million acres of other forest land out of the 751 million acres of U.S. forestland. Implications of forest product use for bioenergy depend on the context of specific locations such as feedstock type and prior management, land conditions, transport and storage logistics, conversion processes used to produce energy, distribution and use. Markets for energy from biomass appear to be ready to grow in response to energy pricing, policy and demand, although recent increases in the supply of natural gas have reduced urgency for new biomass projects. Beyond use in the forest industry and some residences, biopower is not a large-scale enterprise in the United States. Societal choices about forest policy will also affect the carbon cycles on public and private forestland.

Last years there was no case registered of drinking water with the content of radioactive substances exceeding the permissible level. Radiation control of food and agricultural raw products is carried out in several stages: at the place of production, during reprocessing and a control of ready made product. The fact that there was no case of delivery of the products with the content of radionuclides higher than permissible level for sale says about the reliability of the system of the control. The permissible levels of the content of radionuclides are presented for food, drinking water, products of forest industry and agricultural production. 1 tab

Natural disturbances, such as avalanches, snow breakage, insect outbreaks, windthrow or fires shape mountain forests globally. However, in many regions over the past centuries human activities have strongly influenced forest dynamics, especially following natural disturbances, thus limiting our understanding of natural ecological processes, particularly in densely-settled regions. In this contribution we briefly review the current understanding of changes in forest cover, forest structure, and disturbance regimes in the mountain forests across the European Alps over the past millennia. We also quantify changes in forest cover across the entire Alps based on inventory data over the past century. Finally, using the Swiss Alps as an example, we analyze in-depth changes in forest cover and forest structure and their effect on patterns of fire and wind disturbances, based on digital historic maps from 1880, modern forest cover maps, inventory data on current forest structure, topographical data, and spatially explicit data on disturbances. This multifaceted approach presents a long-term and detailed picture of the dynamics of mountain forest ecosystems in the Alps. During pre-industrial times, natural disturbances were reduced by fire suppression and land-use, which included extraction of large amounts of biomass that decreased total forest cover. More recently, forest cover has increased again across the entire Alps (on average +4% per decade over the past 25–115 years). Live tree volume (+10% per decade) and dead tree volume (mean +59% per decade) have increased over the last 15–40 years in all regions for which data were available. In the Swiss Alps secondary forests that established after 1880 constitute approximately 43% of the forest cover. Compared to forests established previously, post-1880 forests are situated primarily on steep slopes (>30°), have lower biomass, a more aggregated forest structure (primarily stem-exclusion stage), and have been more

Ecological consequences of forest elephant declines for Afrotropical forests.

Poaching is rapidly extirpating African forest elephants (Loxodonta cyclotis) from most of their historical range, leaving vast areas of elephant-free tropical forest. Elephants are ecological engineers that create and maintain forest habitat; thus, their loss will have large consequences for the composition and structure of Afrotropical forests. Through a comprehensive literature review, we evaluated the roles of forest elephants in seed dispersal, nutrient recycling, and herbivory and physical damage to predict the cascading ecological effects of their population declines. Loss of seed dispersal by elephants will favor tree species dispersed abiotically and by smaller dispersal agents, and tree species composition will depend on the downstream effects of changes in elephant nutrient cycling and browsing. Loss of trampling and herbivory of seedlings and saplings will result in high tree density with release from browsing pressures. Diminished seed dispersal by elephants and high stem density are likely to reduce the recruitment of large trees and thus increase homogeneity of forest structure and decrease carbon stocks. The loss of ecological services by forest elephants likely means Central African forests will be more like Neotropical forests, from which megafauna were extirpated thousands of years ago. Without intervention, as much as 96% of Central African forests will have modified species composition and structure as elephants are compressed into remaining protected areas. Stopping elephant poaching is an urgent first step to mitigating these effects, but long-term conservation will require land-use planning that incorporates elephant habitat into forested landscapes that are being rapidly transformed by industrial agriculture and logging. © 2017 Society for Conservation Biology.

Factors driving the development of forest energy in Finland

International Nuclear Information System (INIS)

Hakkila, Pentti

2006-01-01

Renewable energy sources play an important role in the Finnish energy and climate strategies which are implemented partly through the Action Plan for Renewable Energy Sources. Enhancement of wood energy plays a key role in the plan. A special emphasis is given to forest chips produced from small-sized trees from early thinnings and above-ground and below-ground residual biomass from regeneration cuttings. The production goal of forest chips is 5 million m 3 solid (10TWh) in 2010. The use of forest chips is promoted by means of environmental taxes, financial aid for investments, and financial support for research, development and commercialization of technology. In 2002, altogether 365 heating and power plants larger than 0.4MW used forest chips. The total consumption was 1.7 million m 3 , the use of small houses and farms included. The growth of use is presently about 350000 m 3 per annum, but reaching the official goal will require an annual growth of 400000 m 3 during this decade. The consumption of roundwood per capita, 15m 3 per annum, is in Finland 20 times as high as the average consumption of the EU countries, respectively. Consequently, residual forest biomass is abundantly available. The capacity of heating and power plants to use forest chips is large enough to meet the goal. However, users require competitive chip prices, good quality control of fuel and reliable supply chains, and new efficient procurement systems are being developed. The paper deals with the drivers of this development: support measures of the Government; strong support to research, development and commercialization of forest chip production from the National Technology Agency Tekes; advanced infrastructure for the procurement of timber for the forest industries; positive attitude and active participation of the forest industries; the active role of leading forest machine and boiler manufacturers, and the possibility to cofire wood and peat fuels in large fluidized bed boilers so as to

Full Text Available The forest is one of the main types of natural resources, the national wealth of the country that has that resource. Forests play an important role not only in maintaining the gas balance of the atmosphere, but also serve as a source of building material, fuel, paper and other useful products. The article presents information about the changes and the current state of the timber industry complex of the Republic of Belarus for the years of independence (since 1991. At the present stage of development of the forest industry was given much attention. This contributes to the high availability of forest resources, which at the moment is 40%. This factor does not only take place from the point of view of satisfaction of domestic needs but also export. Functional role of the complex – provision of economy and population in timber and products from it, as well as a variety of wild and non-wood forest products. The leading place belongs to the complex industrial activities, but a fundamental part of his development is the forestry sector, which supplies them with wood. In connection with the transition of Belarus from OKUD international standard (OKRB 005-2006 statistical reporting according to the 01.01.2011 in the article it is timber industry the timber industry. Timber industry complex of the country has a high export orientation. But the possibility of export potential is not fully used. From sales, the country receives considerably less than Europe. The reason lies in a shallow wood processing. High country’s forest cover attracts investors (China, European countries. With the participation of investors built a number of businesses. The main task of the complex in the coming years is to increase its competitiveness and efficiency and renewal of fixed assets, modernization of existing and establishment of new production facilities for deep processing of wood raw material.

Forecast for the dynamics of forests in Krasnoyarsk Krai

Directory of Open Access Journals (Sweden)

V. A. Sokolov

2017-08-01

Full Text Available Dynamics of the forest ecosystems connects closely with the natural and anthropogenic changes (succession processes, forest fires, windfalls, forest insects, forest diseases, forest harvesting, reforestation, the infrastructure development associated and not associated with forestry and so forth. Authors do not consider the up-to-day problem of global warming on the Earth, as opinions of scientists are controversial. Retrospective analysis of forest dynamics of the Krasnoyarsk Territory for the last 50 years has allowed to assess the impact of these changes on condition of forests. The univocal conclusion of deterioration of forest quality has been drawn. Area of coniferous forests has decreased by 9 %, including the 25 % reduction of mature and overmature forest stands. To forecast forest dynamics, modelling of natural and anthropogenic processes in the forest ecosystems has been applied, taking into account that the existing system of measures for reforestation and tending care of forest actually does not affect dynamics of the forests. The provision about increase in forest harvesting volume to 37.6 million м3 of the Development Strategy of the Krasnoyarsk Forest Industrial Complex has been used for forecasting. It has been proved that such scale of forest harvesting will inevitably lead to the over-cutting of ecological and economic accessible allowable cut that will negatively affect the forest condition in 50 years. Our forecast of forest dynamics of the Krasnoyarsk Territory for the next 50 years has showed that negative changes will continue at the same pace under the current extensive form of forest management. What is more, the maximum decrease of forest area might be in pine forests (32.9 % with the significant increase of broadleaves forests – 22.7 %. To improve the situation in the Russian forest sector, a radical change in the system of forest management is needed.

The composition of soil water under coniferous forests of Murmansk oblast—an industrially developed region of northern Russia—was investigated. The studied objects were dwarf-shrub-green-moss spruce forests and dwarf-shrub-lichen pine forests on Al-Fe-humus podzols ( Albic Rustic Podzols) that are widespread in the boreal zone. The concentrations and removal of organic carbon performing the most important biogeochemical and pedogenic functions were estimated. The results proved significant intra- and inter-biogeocenotic variability in the composition of atmospheric depositions and soil water. Carbon removal with soil water from organic and mineral horizons within elementary biogeoareas (EBGA) under tree crowns was 2-5 and 2-3 times (in some cases, up to 10 times) greater than that in the intercrown areas, respectively. The lowest critical level of mineral nitrogen (0.2 mg/L) was, as a rule, exceeded in tree EBGAs contrary to intercrown areas. Concentrations of sulfates and heavy metals in water of tree EBGA were 3-5 times greater than those in inter-crown areas. Significant inter-biogeocenotic variations related to differences in the height of trees and tree stand density were found. It is argued that adequate characterization of biochemical cycles and assessment of critical levels of components in soil water of forest ecosystems should be performed with due account for the intra- and inter-biogeocenotic variability.

Scenarios for power production with biomass in the Finnish forest industry

International Nuclear Information System (INIS)

Nousiainen, I.K.; Malinen, H.O.; Villa, A.O.

1997-01-01

This study presents three scenarios for power production with biomass in Finnish pulp and paper mills. The basic scenario assumes that the production capacity in the forest industry increases as in the past. The green energy scenario assumes that there is a strong demand from the market for sustainable green energy production. The maximum scenario assumes that the production capacity of chemical pulp increases significantly and the use of wood raw material extends to the maximum level. According to the basic scenario the use of biofuels in the pulp and paper mills will increase from starting level, 3.24 Mtoe in 1992, to 5.07 Mtoe by the year 2010. The utilization potential of biofuels will increase to 5.45 Mtoe in green energy and to 6.43 Mtoe in the maximum biofuels scenario. The power production with biomass will increase from the starting level, 572 MW in 1992, to 930 MW in the basic, to 1 100 MW in the green energy and to 1 670 MW in the maximum biofuels scenario by the year 2010.

2012-06-01

Full Text Available Background and Purpose: Caused by appearance of new stakeholders and diversification of their interests towards forests, different forest-related conflicts emerged worldwide. As a country with economy in transition and relatively young democracy, Bosnia-Herzegovina might be suitable for understanding the roots, actors and varieties of these conflicts. This paper deals with the most frequent forest-related conflicts, main actors involved as well as undertaken actions in order to manage them in Bosnia-Herzegovina. Material and Methods: The theoretical framework is based on the Conflict Management Progress Triangle consisting of three dimensions of conflict: substance, process and relations. As particular focus in this paper is given to conflicts between forestry and wood-processing industry, the primary parties in this study were public forestry companies and wood processing companies. For the purpose of this survey a special questionnaire has been designed. The survey population included the most important actors of forest and wood-processing industry as follows: ministries of forestry, nature protection and physical planning at all levels, managers/owners of wood-processing companies, managers of public forest companies and public forest administration, representatives of the most important environmental NGOs and professional associations, managers of protected areas and water management authorities, heads of forest research institutions, economy of chambers and international institutions. In total 136 questionnaires were collected, out of which 68 respondents identified conflicts between forestry and wood-processing industry as the most important ones. Results and Conclusion: The numerical (tabulated yield table of normative nature presents data given to six yield classes (base age: 25 years including the most important stand structural and yield features expressing in terms of main stand, removing stand (which can be removed in tending

Energy consumption in the mechanical forest industry in 1979 was studied by sending questionnairies to all the significant factories Information was requested on power and heat consumption and installed power in separate process phases. For background information, some aspects of the production process were also requested. The factories which answered the inquiry produced about one half of the doors and windows manufactured in 1979, one sixth of the finger jointed timber and about one third of other products in the branch. The total energy consumption in the branch was 1 556 TJ, 77% was heat. The share of the joinery industry (doors, windows and fixtures) in the total was 2/3, of which 86% was heat energy. The energy needed in the wooden house industry was 219 TJ, in planing works 137 TJ, in the gluelam industry 86 TJ, in finger jointing 76 TJ and in the production of roof trusses about 6 TJ. The investigated brances accounted for 7% of the energy consumption of the whole mechanical forest industry. The energy consumption in producing products of the same type in different factories varied very much. The differences were partially structural. However, there is considerable room for energy savings in many of the factories.

Full Text Available Forest destruction both in the form of deforestation and degradation continues. Forest management on the basis of partnership with the community is also one of forest management methods to tackle deforestation. Agroforestry company has a commitment to support legal teak supplies and support teak forest afforestation. Plant breeding efforts were being undertaken all national agroforestry company and implemented in cooperation with BPPT as a partner to obtain superior teak plants. A problem in producing a superior teak seedling is the high cost of seed production. Because of this, teak seedlings produced. Materials used for the study were obtained from questionnaires carried out by employees. The data were analyzed using descriptive analysis, structured equation model and value stream analysis tools. The results reveal that the main factors affecting the production process of teak seedlings are transportation, process, human, material and machine. The improvement of production system teak seedlings will be applied in the following order of priority: transportation with 60.8% influential level, motion with 49.5% effective level, defect with 3.8% influential level, and inventory with 2.5% influential level.

Although the Australian forest plantation industry acknowledges that there is a role for corporate social responsibility (CSR) in forest management, there is confusion as to what this constitutes in practice. This paper describes the conflicts between internal and external stakeholder views on CSR in plantation forestry. We conducted in-depth interviews with key informants across three plantation management regions in Australia: Tasmania, the Green Triangle and south-west Western Australia. We interviewed a range of stakeholders including forest company employees, local councils, Indigenous representatives, and environmental non-government organisations. CSR-related initiatives that stakeholders believed were important for plantation management included the need for community engagement, accountability towards stakeholders, and contribution to community development and well-being. Although there was wide support for these initiatives, some stakeholders were not satisfied that forest companies were actively implementing them. Due to the perception that forest companies are not committed to CSR initiatives such as community engagement, some stakeholder expectations are not being satisfied. Copyright © 2012 Elsevier Ltd.

Is more serious damage of forest observed in the vicinity of nuclear reactors. How are those decline patterns to be explained. Does the combined effect of radioactivity and different air pollutants (such as nitrogen oxides, sulfur dioxide, oxidants etc.) have an influence in the decline of the forest. In what way do synergisms, i.e. mutually enhanced effects, participate. How does natural and artificial radioactivity affect the chemistry of air in the polluted atmosphere. What does this mean for the extension of nuclear energy, especially for the reprocessing plant planned. Damage in the forests near nuclear and industrial plants was mapped and the resulting hypotheses on possible emittors were statistically verified. Quantitative calculations as to the connection between nuclear energy and forest decline were carried through: they demand action. (orig./HP) [de

Full text: The Radiation Protection Program of the Environmental Protection Agencies of countries employ scientists, engineers, statisticians, economists, lawyers, policy analysts, and public affairs professionals amongst others. These professionals aim to protect workers, the general public, and the environment from harmful radiation exposures and to provide the technical basis for radiation protection policies and regulations. Professionals include Health physicists, Bio statistician, Radio chemist, Radio ecologist, Radio biologist etc. With a large proportion of the population of the nuclear workforce of many countries now approaching retirement age, existing power plants of these countries will be hard pressed to find enough qualified professionals to support their operations. The potential shortage of skilled manpower not only affects utilities, but also impacts the entire nuclear infrastructure, including national laboratories, federal and state agencies, nuclear technology vendors and manufacturing companies, nuclear construction companies, and university nuclear engineering departments. Manpower requirements exist in the nuclear power industry, universities and research establishments, hospitals, government departments, general industry e.g. radiography, transport, instrumentation etc., specialist contractors, agencies and consultancies serving radiation protection. India is no exception. India has the world's 12 th largest economy. Assuming India's average growth rate p.a. of more than 5%, total GDP by 2050 will increase substantially which will require proportionate increase of manpower for all industries. Also chance of brain drain is very high from developing countries e.g. from India to developed countries because of much higher pay and better lifestyle as there will be shortage of manpower in developed countries as explained above. With population growth to be stabilized in future in India, the working age population may not increase in the year 2030

According to the Seventh National Forest Inventory (2004-2008), China's forests cover an area of 195.45 million ha, or 20.36% of the total land area. China has the most rapidly increasing forest resources in the world. However, China is also a country with serious forest pest problems. There are more than 8,000 species of potential forest pests in China, including insects, plant diseases, rodents and lagomorphs, and hazardous plants. Among them, 300 species are considered as economically or ecologically important, and half of these are serious pests, including 86 species of insects. Forest management and utilization have a considerable influence on the stability and sustainability of forest ecosystems. At the national level, forestry policies always play a major role in forest resource management and forest health protection. In this paper, we present a comprehensive overview of both achievements and challenges in forest management and insect pest control in China. First, we summarize the current status of forest resources and their pests in China. Second, we address the theories, policies, practices and major national actions on forestry and forest insect pest management, including the Engineering Pest Management of China, the National Key Forestry Programs, the Classified Forest Management system, and the Collective Forest Tenure Reform. We analyze and discuss three representative plantations-Eucalyptus, poplar and Masson pine plantations-with respect to their insect diversity, pest problems and pest management measures.

Comparing Sustainable Forest Management Certifications Standards: A Meta-analysis

Directory of Open Access Journals (Sweden)

Michael Rawson. Clark

2011-03-01

Full Text Available To solve problems caused by conventional forest management, forest certification has emerged as a driver of sustainable forest management. Several sustainable forest management certification systems exist, including the Forest Stewardship Council and those endorsed by the Programme for the Endorsement of Forest Certification, such as the Canadian Standards Association - Sustainable Forestry Management Standard CAN/CSA - Z809 and Sustainable Forestry Initiative. For consumers to use certified products to meet their own sustainability goals, they must have an understanding of the effectiveness of different certification systems. To understand the relative performance of three systems, we determined: (1 the criteria used to compare the Forest Stewardship Council, Canadian Standards Association - Sustainable Forestry Management, and Sustainable Forestry Initiative, (2 if consensus exists regarding their ability to achieve sustainability goals, and (3 what research gaps must be filled to improve our understanding of how forest certification systems affect sustainable forest management. We conducted a qualitative meta-analysis of 26 grey literature references (books, industry and nongovernmental organization publications and 9 primary literature references (articles in peer-reviewed academic journals that compared at least two of the aforementioned certification systems. The Forest Stewardship Council was the highest performer for ecological health and social sustainable forest management criteria. The Canadian Standards Association - Sustainable Forestry Management and Sustainable Forestry Initiative performed best under sustainable forest management criteria of forest productivity and economic longevity of a firm. Sixty-two percent of analyses were comparisons of the wording of certification system principles or criteria; 34% were surveys of foresters or consumers. An important caveat to these results is that only one comparison was based on

DEPENDENCE OF GRASS COVER TAXONOMIC AND ECOLOGICAL STRUCTURE ON THE ANTHROPOGENIC IMPACT IN FOREST ECOSYSTEMS

Full Text Available Pine forests Chigirinsky Bor grow on fresh sod-podzolic soils formed on ancient alluvial deposits. Pine forests are characterized by stringent moisture regimes and constantly suffer from lack of productive moisture in soil.  Industrial development of Cherkasy in 60th years of ХХ century leaded air pollution and emissions of SO2, NOx, NH3, and dust. This contributed to significant negative influence on the surrounding forest ecosystems from enterprises of  Cherkassy industrial agglomeration. The grass cover in pine stands of Chigirinsky Bor transforms into xerophytic grasses and ruderal communities under the impact of negative biotic and abiotic factors. They are namely the anthropogenic violation of forest conditions, stands decline, recreational and industrial tree crowns understocking, xerophytic and heliophytic transformations of forest conditions. All the above mentioned caused strong ruderal and adventive transformation of grass cover. We registered the changes in nitrophilous plant spread regards the Cherkasy industrial agglomeration approaching which emits toxic with nitrogen-containing gases. Adventive and other non-forest species displace ferns and mosses, the ratio of ecomorfs is also changes due to increase of the quantity and development activation of annuals, xerophytic, ruderal, and nitrofil plants. The Asteraceae/Brassicaceae 3:1 ratio indicates significant anthropogenic violations in the region. We fixed the xerophytic, ruderal, and adventive transformation of grass cover in forest ecosystems. It is also founded the tendency of expanding the fraction of mesophilic plant species due to alterations in water regime (creation of Kremenchug reservoir and draining of floodplain Tyasmyn. When approaching the Cherkasy industrial agglomeration the grass cover degradation is clearly observed on the environmental profile. All this causes the forest ecosystem degradation and gradual loss of forest vegetation typical characteristics. We

African forests, which host some of the world's richest biodiversity, are rapidly diminishing. The loss of flora and fauna includes economically and socially important insects. Honey bees and silk moths, grouped under commercial insects, are the source for insect-based enterprises that provide income to forest-edge communities to manage the ecosystem. However, to date, research output does not adequately quantify the impact of such enterprises on buffering forest ecosystems and communities from climate change effects. Although diseases/pests of honey bees and silk moths in Africa have risen to epidemic levels, there is a dearth of practical research that can be utilized in developing effective control mechanisms that support the proliferation of these commercial insects as pollinators of agricultural and forest ecosystems. This review highlights the critical role of commercial insects within the environmental complexity of African forest ecosystems, in modern agroindustry, and with respect to its potential contribution to poverty alleviation and pollination services. It identifies significant research gaps that exist in understanding how insects can be utilized as ecosystem health indicators and nurtured as integral tools for important socioeconomic and industrial gains.

The overall objective of the thesis is to analyse the procurement competition for forest resources in Sweden. The thesis consists of an introductory part and two self-contained papers. In paper I a translog cost function approach is used to analyse the factor substitution in the sawmill industry, the pulp and paper industry and the heating industry in Sweden over the period 1970 to 2008. The estimated parameters are used to calculate the Allen and Morishima elasticities of substitution as well as the price elasticities of input demand. The utilisation of forest resources in the energy sector has been increasing and this increase is believed to continue. The increase is, to a large extent, caused by economic policies introduced to reduce the emission of greenhouse gases. Such policies could lead to an increase in the procurement competition between the forest industries and the energy sector. The calculated substitution elasticities indicate that it is easier for the heating industry to substitutes between by-products and logging residues than it is for the pulp and paper industry to substitute between by-products and roundwood. This suggests that the pulp and paper industry could suffer from an increase in the procurement competition. However, overall the substitutions elasticities estimated in our study are relatively low. This indicates that substitution possibilities could be rather limited due to rigidities in input prices. This result suggests that competition of forest resources also might be relatively limited. In paper II a partial equilibrium model is constructed in order to asses the effects an increasing utilisation of forest resources in the energy sector. The increasing utilisation of forest fuel is, to a large extent, caused by economic policies introduced to reduce the emission of greenhouse gases. In countries where forests already are highly utilised such policies will lead to an increase in the procurement competition between the forest sector and

Social impact mitigation strategies are implemented by the proponents of policies and projects with the intent of reducing the negative, and increasing the positive social impacts of their activities, and facilitating the achievement of policy/project goals. Evaluation of mitigation strategies is critical to improving their future success and cost-effectiveness. This paper evaluates two Forest Industry Structural Adjustment Packages (FISAP) implemented in Australia in the 1990s to 2000s as part of broader policy changes that reduced access to timber from publicly owned native forests. It assesses the effectiveness of the structure, design, implementation and monitoring of the FISAPs, and highlights the interactions between these four elements and their influence on social impacts. The two FISAPs were found to be effective in terms of reducing negative impacts, encouraging positive impacts and contributing towards policy goals, although they did not mitigate negative impacts in all cases, and sometimes interacted with external factors and additional policy changes to contribute to significant short and long term negative impacts. -- Highlights: ► Mitigation strategies aim to reduce negative and enhance positive social impacts ► Mitigation strategy design, implementation, and monitoring are critical to success ► Effective mitigation enhanced the capacity of recipients to respond to change ► Mitigation strategies influenced multiple interacting positive and negative impacts ► Success required good communication, transparency, support, resources and timing

Making Forest Values Work: Enhancing Multi-Dimensional Perspectives towards Sustainable Forest Management

Directory of Open Access Journals (Sweden)

Doni Blagojević

2016-06-01

Full Text Available Background and Purpose: Sustainability, sustainable development and sustainable forest management are terms that are commonly, and interchangeably used in the forest industry, however their meaning take on different connotations, relative to varying subject matter. The aim of this paper is to look at these terms in a more comprehensive way, relative to the current ideology of sustainability in forestry. Materials and Methods: This paper applies a literature review of the concepts of: i sustainable development; ii sustainable forest management; and iii economic and non-economic valuation. The concepts are viewed through a historical dimension of shifting paradigms, originating from production- to service-based forestry. Values are discussed through a review of general value theory and spatial, cultural and temporal differences in valuation. Along the evolution of these concepts, we discuss their applicability as frameworks to develop operational guidelines for forest management, relative to the multi-functionality of forests. Results and Conclusions: Potential discrepancies between the conceptual origins of sustainable development and sustainable forest management are highlighted, relative to how they have been interpreted and diffused as new perceptions on forest value for the human society. We infer the current paradigm may not reflect the various dimensions adequately as its implementation is likely to be more related to the distribution of power between stakeholders, rather than the value stakeholders’ place on the various forest attributes.

The handling and sustainable use of the forest ecosystems of the country is one of the purposes of the politicians from Colombia, in particular, and of the world in general; and the forest handling plans (PMF) they are constituted in one of the existent technical and legal instruments for its administration. However, the current national situation as for the use and conservation of the natural forests points out that the PMF is not completing its function and that they suffer of a hypothetical suitability lack for such ends. With base in the previous situation, it decided to carry out this investigation that was guided to evaluate and to determine the suitability of the PMF and the corresponding forest inventories, as instruments to plan and to carry out the handling and the use of the natural forests in Colombia, taking like case study; the Municipalities of Olaya Herrera, Francisco Pizarro, Mosquera, Roberto Payan and Magui, in the pacific coast of the Narino Department, that is one of the main areas of forest use in the country and supplying of an important volume of wood for the national industry, reason for which the use of the local forests is there the main productive activity of the black communities seated. The study was carried out during a lapse of six months, including two months of field work, in the mark of the Project: Application and Evaluation of Approaches and Indicators for the sustainable ordination of the natural forests, carried out under the auspices of the Ministry of the environment of Colombia and the International Organization of Tropical Wood - IOTW

efficiency for the heat upgrading process. The project was started with a questionnaire to the forest industry, including questions on temperature requirements for the upgraded heat. Out of 16 addressed and evaluated industries, three were selected for a more in-deep assessment. The following mills were selected: Braviken, Froevi and Malaa saw mill. Cost effective process solutions production of both process steam and district heating were studied for a number of waste heat sources. Upgraded waste heat is primary considered on the level of 85-90 deg C, but also hot water and process steam on 1-3 bar level. Waste heat sources evaluated in the techno-economic assessment are paper machine outlet, flue gases from power and recovery boilers as well as from lumber dryers. The results within every category are considered to be relatively general for similar companies in the forest industry. For all cases, a heat factor (coefficient of performance) 1.5-1.7 is calculated, i.e. the relation between upgraded waste heat (when applicable also incl. process steam) and the driving steam. A feasibility study for the three industries was carried out for four different process solutions for a pre-fabricated module of approximately 5 MW upgraded waste heat capacity. The investment cost for these modules was calculated to MSEK 14-19 on a +-30% level. The specific investment cost in relation to the upgraded waste heat capacity, varies between SEK 2,700 and 3,700 per kW of useful heat. The economic assessment shows a payback time under 2 years for three of the four processes that produce hot water and LLP steam. The forth process, for upgrading waste heat to LP steam (3 bara) via steam compression, is not profitable with the present assumptions. With the current energy costs there are no incentives to upgrade waste heat to LP steam with an absorption heat pump and steam compression. The study has shown that this novel absorption heat pump technology has technical and economical potential to

An outlook for sustainable forest bioenergy production in the Lake States

International Nuclear Information System (INIS)

Becker, Dennis R.; Skog, Kenneth; Hellman, Allison; Halvorsen, Kathleen E.; Mace, Terry

2009-01-01

The Lake States region of Minnesota, Wisconsin and Michigan offers significant potential for bioenergy production. We examine the sustainability of regional forest biomass use in the context of existing thermal heating, electricity, and biofuels production, projected resource needs over the next decade including existing forest product market demand, and impacts on price and feasibility. Assuming $36 per dry tonne at roadside, 4.1 million dry tonnes of forest biomass could be available region-wide. However, less is likely available due to localized environmental and forest cover type constraints, and landowner willingness to harvest timber. Total projected demand of 5.7 million dry tonnes, based on current and announced industry capacity, exceeds estimates of biomass availability, which suggests that anticipated growth in the forest-based bioeconomy may be constrained. Attaining projected demand will likely require a combination of higher cost feedstocks, integration of energy and non-energy uses, and careful management to meet environmental constraints. State distinctions in biomass harvest guidelines and the propensity for third-party forest certification will be critical in providing environmental safeguards. The cumulative effect of policy initiatives on biomass competition are discussed in the context of an emerging Lake States bioeconomy.

Geomorphology and forest management in New Zealand's erodible steeplands: An overview

Science.gov (United States)

Phillips, Chris; Marden, Michael; Basher, Les R.

2018-04-01

In this paper we outline how geomorphological understanding has underpinned forest management in New Zealand's erodible steeplands, where it contributes to current forest management, and suggest where it will be of value in the future. We focus on the highly erodible soft-rock hill country of the East Coast region of North Island, but cover other parts of New Zealand where appropriate. We conclude that forestry will continue to make a significant contribution to New Zealand's economy, but several issues need to be addressed. The most pressing concerns are the incidence of post-harvest, storm-initiated landslides and debris flows arising from steepland forests following timber harvesting. There are three areas where geomorphological information and understanding are required to support the forest industry - development of an improved national erosion susceptibility classification to support a new national standard for plantation forestry; terrain analysis to support improved hazard and risk assessment at detailed operational scales; and understanding of post-harvest shallow landslide-debris flows, including their prediction and management.

Full Text Available Combining protected areas with natural forest timber concessions may sustain larger forest landscapes than is possible via protected areas alone. However, the role of timber concessions in maintaining natural forest remains poorly characterized. An estimated 57% (303,525 km² of Kalimantan's land area (532,100 km² was covered by natural forest in 2000. About 14,212 km² (4.7% had been cleared by 2010. Forests in oil palm concessions had been reduced by 5,600 km² (14.1%, while the figures for timber concessions are 1,336 km² (1.5%, and for protected forests are 1,122 km² (1.2%. These deforestation rates explain little about the relative performance of the different land use categories under equivalent conversion risks due to the confounding effects of location. An estimated 25% of lands allocated for timber harvesting in 2000 had their status changed to industrial plantation concessions in 2010. Based on a sample of 3,391 forest plots (1×1 km; 100 ha, and matching statistical analyses, 2000-2010 deforestation was on average 17.6 ha lower (95% C.I.: -22.3 ha- -12.9 ha in timber concession plots than in oil palm concession plots. When location effects were accounted for, deforestation rates in timber concessions and protected areas were not significantly different (Mean difference: 0.35 ha; 95% C.I.: -0.002 ha-0.7 ha. Natural forest timber concessions in Kalimantan had similar ability as protected areas to maintain forest cover during 2000-2010, provided the former were not reclassified to industrial plantation concessions. Our study indicates the desirability of the Government of Indonesia designating its natural forest timber concessions as protected areas under the IUCN Protected Area Category VI to protect them from reclassification.

The writings and speeches in this book have been selected to illustrate Jack Westoby's contributions to international forestry over the last two decades and more, and to show something of the evolution of his thinking. The problems he addresses are ones central to international forest policy and to the proper social responsibilities of foresters. This paper covers the following topics: Part I is a selection of papers which Westoby wrote during the 1960s on forest industries and their part in propelling economic development. The papers of Part II explore the responsibilities and dilemmas of the forestry profession in deciding which, among conflicting interests, to serve. Part III develops and enlarges Westoby's ideas of what forestry should be about-which he earlier defined as making trees serve people

Forest Rent as an Object of Economic Analysis

Directory of Open Access Journals (Sweden)

Lisichko Andriyana M.

2018-01-01

Full Text Available The article is aimed at researching the concept of forest rent as an object of economic analysis. The essence of the concept of «forest rent» has been researched. It has been defined that the forest rent is the object of management of the forest complex of Ukraine as a whole and forest enterprises in particular. Rent for special use of forest resources is the object of interest om the part of both the State and the corporate sector, because its value depends on the cost of timber for industry and households. Works of scholars on classification of rents were studied. It has been determined that the rent for specialized use of forest resources is a special kind of natural rent. The structure of constituents in the system of rent relations in the forest sector has been defined in accordance with provisions of the tax code of Ukraine.

Public perceptions of risk to forest biodiversity.

Science.gov (United States)

McFarlane, Bonita L

2005-06-01

This study examines the perceived risks to forest biodiversity and perceived effectiveness of biodiversity conservation strategies among the general public. It tests the hypotheses that perceived risk to forest biodiversity is influenced by cognitive factors (value orientation and knowledge) and social-cultural factors (such as gender and environmental membership) and that risk perceptions influence other cognitive constructs such as support for natural resource policy and management. Data were collected from a sample of the general public (n= 596) in British Columbia, Canada by mail survey in 2001. Results show that insects and disease were perceived as the greatest risk. Educating the public and industry about biodiversity issues was perceived as a more effective conservation strategy than restricting human uses of the forest. Value orientation was a better predictor of perceptions of risk and perceived effectiveness of conservation strategies than knowledge indicators or social-cultural variables. Examining the indirect effects of social-cultural variables, however, revealed that value orientation may amplify the effect of these variables and suggests that alternative paths of influence should be included. Perceived risk showed an inconsistent association with perceived effectiveness of conservation strategies.

In 1998 the electricity production in industrial installations in Germany was about 40 TWh. This accounts for 66% of the total electricity production with CHP plants in Germany. The presentation will analyse the developments for industrial CHP throughout the last 10 years and will try to explain the developments. The difficult situation for the industrial CHP shows up from the sharp decrease of the total installed capacity by about 2000 MW during 1996 and 1998, already in approach of the full liberalisation of the electricity market in Germany, which has resulted in further and even more plant shut downs. Based on a survey of the German Association of Industrial Autoproducers and Energy Consumers (VIK) plants with a total capacity of 500 MW were closed down in 1999, and about 60% of the industrial CHP installation are facing serious economic problems. The presentation will show some sample economic calculations for different types of plants (Coal fired steam turbines, gas turbines, IC-engines). These results will be compared to the actual energy cost structures for industrial customers. Based on large over capacity in power generation, the offered electricity prices for industrial customers tend to be in the range off the operating cost of the industrial CHP plants. One way out of this dilemma is sometimes the outsourcing and contracting of CHP installations, which has been and still is a growing business in Germany, and utilities regard these options as a possibility to keep their industrial customers.

The amount of economically producible energy wood, the effects of energy wood harvesting on the development of forests, and the changes required by harvesting of energy wood on the forest processing instructions at the area of the Forestry Board of Central Ostrobothnia were investigated. The calculations were made using the Metsaelaskelma (Forest calculation) MELA program. At the energy wood production cost level 45 FIM/MWh, and when the energy wood competes with the industrial wood, the annual energy wood accumulation was about 120 000 m{sup 3}, which would be sufficient for three heating plants using about 100 000 m{sup 3} of chips annually. Even if the fellings of industrial wood would remain on the low level of the beginning of 1990`s the harvesting of energy wood would not become much higher than this. By harvesting of energy wood it is impossible to effect on the forestry state and the future development of the Finnish forests remarkably before the separate harvesting of energy wood becomes profitable. Harvesting of felling residues from spruce predominant final cutting sites and integrated harvesting of pine predominant first thinning forests would be more profitable harvesting methods than the separate harvesting. On the basis of the information on the future net income obtained from the forests, the harvesting of the energy wood seemed, however, to be a profitable alternative. Harvesting of energy wood was not observed to effect on the forest cultivation models remarkably because the harvesting of energy wood was just a small fragment of the complete forest processing chain (first thinning phase) studied, and the economical profitability controlled the thinnings strongly independently on where the wood was utilized.

Full Text Available The quarrying industry is changing the local landscape, forming deep open pits and spoil heaps in close proximity to them, especially lignite mines. The impact can include toxic soil material (low pH, heavy metals, oxidations etc. which is the basis for further reclamation and afforestation. Forests that stand on spoil heaps have very different growth conditions because of the relief (slope, aspect, wind and rainfall shadows, supply of solar energy, etc. and type of soil that is deposited. Airborne laser scanning (ALS technology deliver point clouds (XYZ and derivatives as raster height models (DTM, DSM, nDSM=CHM which allow the reception of selected 2D and 3D forest parameters (e.g. height, base of the crown, cover, density, volume, biomass, etc. The automation of ALS point cloud processing and integrating the results into GIS helps forest managers to take appropriate decisions on silvicultural treatments in areas with failed plantations (toxic soil, droughts on south-facing slopes; landslides, etc. or as regular maintenance. The ISOK country-wide project ongoing in Poland will soon deliver ALS point cloud data which can be successfully used for the monitoring and management of many thousands of hectares of destroyed post-industrial areas which according to the law, have to be afforested and transferred back to the State Forest.

Fire in the forest: The air quality dilemma

International Nuclear Information System (INIS)

Core, J.E.

1992-01-01

Fire has long been an important tool of forest land managers. Air regulators responsible for assuring that the provisions of the Clean Air Act are met, see smoke from forest land burning as just another source of air pollution. From an air quality standpoint, pollutants released by forestry burning practices are no different than those emitted from other sources since smoke is smoke, regardless of whether it comes from a woodstove, a wood products industry stack, agricultural burning, or forestry land management. This paper discusses the dilemma that air quality and forest land managers face when balancing air quality protection with the role of fire in the forest

Full Text Available Changes in forest area may include changes in forest designation through exchange process and release of forest areas such as for plantation and industry. The changes will have direct impact on the community, especially those adjacent to the changed forest areas. The study was conducted to find out knowledge and expectations of forest communities as a result of changing in forest areas in Indragiri Hilir Regency, Riau Province.The data were collected by using community interview method. Respondents were selected by purposive random sampling. The results showed that community's knowledge to the forest, benefits and consequences of forest destruction is negative, while community's knowledge to the existence oil palm companies is positive. This is because community awareness on the forest is still low. The community generally agree if forest area that become oil palm plantations be released from forest area designation, and they expect increase in their income. This is motivated by the fact that the land that had been cultivated for coconut plantations is no longer productive, due to frequent sea water intrusion. Cooperation with company is expected to help the communities build embankments on lands affected by seawater intrusion so that the land can be reused

An interdisciplinary, outcome-based approach to astmospheric CO2 mitigation with planted southern pine forests

Martin, T.; Fox, T.; Peter, G.; Monroe, M.

2012-12-01

The Pine Integrated Network: Education, Mitigation and Adaptation Project ("PINEMAP") was funded by National Institute of Food and Agriculture to produce outcomes of enhanced climate change mitigation and adaptation in planted southern pine ecosystems. The PINEMAP project leverages a strong group of existing networks to produce synergy and cooperation on applied forestry research in the region. Over the last 50 years, cooperative research on planted southern pine management among southeastern U.S. universities, government agencies, and corporate forest landowners has developed and facilitated the widespread implementation of improved genetic and silvicultural technology. The impact of these regional research cooperatives is difficult to overstate, with current members managing 55% of the privately owned planted pine forestland, and producing 95% of the pine seedlings planted each year. The PINEMAP team includes the eight major forestry cooperative research programs, scientists from eleven land grant institutions, the US Forest Service, and climate modeling and adaptation specialists associated with the multi-state SE Climate Consortium and state climate offices. Our goal is to create and disseminate the knowledge that enables landowners to: harness planted pine forest productivity to mitigate atmospheric CO2; more efficiently use nitrogen and other fertilizer inputs; and adapt their forest management to increase resilience in the face of changing climate. We integrate our team's infrastructure and expertise to: 1) develop breeding, genetic deployment and innovative management systems to increase C sequestration and resilience to changing climate of planted southern pine forests ; 2) understand interactive effects of policy, biology, and climate change on sustainable management; 3) transfer new management and genetic technologies to private industrial and non-industrial landowners; and 4) educate a diverse cross-section of the public about the relevance of forests

Sustainable Biofuels from Forests: Woody Biomass

Directory of Open Access Journals (Sweden)

Edwin H. White

2011-11-01

Full Text Available The use of woody biomass feedstocks for bioenergy and bioproducts involves multiple sources of material that together create year round supplies. The main sources of woody biomass include residues from wood manufacturing industries, low value trees including logging slash in forests that are currently underutilized and dedicated short-rotation woody crops. Conceptually a ton of woody biomass feedstocks can replace a barrel of oil as the wood is processed (refined through a biorefinery. As oil is refined only part of the barrel is used for liquid fuel, e.g., gasoline, while much of the carbon in oil is refined into higher value chemical products-carbon in woody biomass can be refined into the same value-added products.

The Role of Eucalyptus Globulus Forest and Products in Carbon Sequestration

International Nuclear Information System (INIS)

Arroja, L.; Dias, A.C.; Capela, I.

2006-01-01

This study is a contribution to the ongoing debate about the selection of the approach for carbon accounting in wood products to be used, in the future, in the national greenhouse gas inventories under the UNFCCC (United Nations Framework Convention on Climate Change). Two accounting approaches are used in this analysis: the stock-change approach and the atmospheric-flow approach. They are applied to the Portuguese Eucalyptus globulus forest sector. To achieve this objective, the fluxes of wood removed from the forest are tracked through its life cycle, which includes products manufacture (mainly pulp and paper), use and final disposal (landfilling, incineration and composting). This study develops a framework to the estimation of carbon sequestration in the forest of E. globulus, a fast growing species, more specifically, in the calculation of the conversion factors such as bark and foliage percentages and densities, used to convert wood volumes into total biomass. A mass balance approach based on real data from mills is also proposed, in order to assess carbon emissions from wood processing. The results show that E. globulus forest sector was a carbon sink, but the magnitude of the carbon sequestration differs substantially depending on the accounting approach used. The contribution of the forest ecosystem was smaller than the aggregated contribution of wood products in use and in landfills (including industrial waste), which reinforces the role that wood products play in national carbon budgets

This project supported research on science and technology that forms a basis for integrated forest product refinery for co-production of chemicals, fuels and materials using existing forest products industry infrastructure. Clear systems view of an Integrated Forest Product Refinery (IFPR) allowed development of a compelling business case for a small scale technology demonstration in Old Town ME for co-production of biofuels using cellulosic sugars along with pulp for the new owners of the facility resulting in an active project on Integrated Bio-Refinery (IBR) at the Old Town Fuel & Fiber. Work on production of advanced materials from woody biomass has led to active projects in bioplastics and carbon nanofibers. A lease for 40,000 sq. ft. high-bay space has been obtained to establish a Technology Research Center for IFPR technology validation on industrially relevant scale. UMaine forest bioproducts research initiative that began in April 2006 has led to establishment of a formal research institute beginning in March 2010.

Håkan Olsson

2012-09-01

Full Text Available The introduction of Airborne Laser Scanning (ALS to forests has been revolutionary during the last decade. This development was facilitated by combining earlier ranging lidar discoveries [1–5], with experience obtained from full-waveform ranging radar [6,7] to new airborne laser scanning systems which had components such as a GNSS receiver (Global Navigation Satellite System, IMU (Inertial Measurement Unit and a scanning mechanism. Since the first commercial ALS in 1994, new ALS-based forest inventory approaches have been reported feasible for operational activities [8–12]. ALS is currently operationally applied for stand level forest inventories, for example, in Nordic countries. In Finland alone, the adoption of ALS for forest data collection has led to an annual savings of around 20 M€/year, and the work is mainly done by companies instead of governmental organizations. In spite of the long implementation times and there being a limited tradition of making changes in the forest sector, laser scanning was commercially and operationally applied after about only one decade of research. When analyzing high-ranked journal papers from ISI Web of Science, the topic of laser scanning of forests has been the driving force for the whole laser scanning research society over the last decade. Thus, the topic “laser scanning in forests” has provided a significant industrial, societal and scientific impact. [...

As part of its Industries of the Future strategy, the Industrial Technologies Program within the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy works with energy-intensive industries to improve efficiency, reduce waste, and increase productivity. These seven Industries of the Future (IOFs) – aluminum, chemicals, forest products, glass, metal casting, mining, and steel – rely on several other so-called “supporting industries” to supply materials and processes necessary to the products that the IOFs create. The supporting industries, in many cases, also provide great opportunities for realizing energy efficiency gains in IOF processes.

Full Text Available With recently announced federal funding and subsidies to redevelop vacant mills and the communities they were in, the forest products industry in Maine is poised to gain its momentum once again. One of the important components influencing the cost of delivered forest products is transportation. A recent study in the region has shown that the location and availability of markets along with lack of skilled labor force are the major challenges faced by the forest products transportation sector in Maine. This study was focused on developing a management guideline which included various field level options for improving trucking enterprises in Maine. For this, a qualitative research approach utilizing a case study research tradition was employed, with in-depth semi-structured interviews with professionals directly related to the forest products transportation sector used for data generation. Thirteen semi-structured interviews were conducted, with each being audio recorded and later transcribed verbatim. Interview transcriptions were analyzed using NVivo 11. Suggestions, like increasing benefits to drivers and providing training, were proposed for challenges related to manpower shortage, while the marketing of new forest products and adjustment in some state-level policies were proposed for challenges related to the forest products market condition of the state.

Fuelling a BioMess. Why Burning Trees for Energy Will Harm People,the Climate and Forests

International Nuclear Information System (INIS)

Mainville, N.

2011-10-01

The global bioenergy boom is driven by a surge of interest in biological materials - or biomass - to produce heat, electricity and fuels. In a world of declining fossil fuel deposits and rising fuel prices, industries and governments are hastily switching back to an ancient source of energy: trees. In Canada, forest bioenergy once referred to a sensible, small-scale and local solution to produce heat and power by using mill and pulp residues at the plant. This is no longer the case. Now, the sector is rapidly developing into large-scale, industrial use of natural forests for energy. This is due to new government biomass extraction policies and subsidies. Without public hearings, exhaustive science or adequate environmental standards in place, provincial governments have allocated large volumes of biomass from publicly owned forests to be burnt, thereby radically changing the way forests are used in Canada. This is turning to ash sustainable job opportunities, threatening the greening of the forest sector and the value-added product trend that has been emerging in recent years. The premise on which the forest bioenergy industry is based - i.e. that woody biomass is infinitely available and that burning it is clean and carbon neutral - does not stand up to scientific scrutiny and needs to be revisited. Exploiting forests for energy increases carbon emissions and contributes to climate change for decades, even centuries, before proving to be better than fossil fuels. The Canadian government has failed to report those emissions. Accounting properly for the climate footprint of forest bioenergy is crucial if governments really want to tackle climate change and meet greenhouse gas reduction targets by 2020 and 2050. Large-scale combustion of wood is also a health hazard due to significant toxic emissions of fine particulates, carbon monoxide and heavy metals. Because enormous amounts of forest biomass are needed to produce small amounts of energy, drastic ecological

SOUTH AMERICA: INDUSTRIAL ROUNDWOOD SUPPLY POTENTIAL

Directory of Open Access Journals (Sweden)

Ronalds W. Gonzalez

2008-02-01

Full Text Available South America has substantial potential to expand its forest plantations and raw material supply. From 1997 to 2005, South America had a high annual growth rate in the production of industrial roundwood, with Brazil and Chile being the most important countries. In the same period, Asia had the only negative regional production growth rate in the world, and China became the largest round wood importer in the world. This paper summarizes the status of production, consumption, imports, and exports of industrial roundwood and forest products in South America. Produc-tion and exports from South America have continually increased at annual growth rates exceeding the forestry sector in general and the U.S. in particular. Based on timber growing investments to date, a strong timber production and forest products manufacturing sector has developed in the Southern Cone countries of Chile, Brazil, Argentina, and Uruguay, and is increasing in other countries in Latin America. There will be continued opportunities for forest plantations and new manufacturing facilities throughout South America, tempered somewhat by perceived country financial and political risks. These opportunities will allow South America to increase its share of world production and increase imports to North America and to Asia.

Expansion of Industrial Plantations Continues to Threaten Malayan Tiger Habitat

2017-07-01

Full Text Available Southeast Asia has some of the highest deforestation rates globally, with Malaysia being identified as a deforestation hotspot. The Malayan tiger, a critically endangered subspecies of the tiger endemic to Peninsular Malaysia, is threatened by habitat loss and fragmentation. In this study, we estimate the natural forest loss and conversion to plantations in Peninsular Malaysia and specifically in its tiger habitat between 1988 and 2012 using the Landsat data archive. We estimate a total loss of 1.35 Mha of natural forest area within Peninsular Malaysia over the entire study period, with 0.83 Mha lost within the tiger habitat. Nearly half (48% of the natural forest loss area represents conversion to tree plantations. The annual area of new plantation establishment from natural forest conversion increased from 20 thousand ha year−1 during 1988–2000 to 34 thousand ha year−1 during 2001–2012. Large-scale industrial plantations, primarily those of oil palm, as well as recently cleared land, constitute 80% of forest converted to plantations since 1988. We conclude that industrial plantation expansion has been a persistent threat to natural forests within the Malayan tiger habitat. Expanding oil palm plantations dominate forest conversions while those for rubber are an emerging threat.

Product Life Cycle of the Manufactured Home Industry

Directory of Open Access Journals (Sweden)

Gavin Wherry

2014-09-01

Full Text Available Residential construction consumes an estimated 26 percent of the total U.S. wood harvest and thus plays an important role in the forest products value chain. While being a relatively small part of the U.S. residential construction market, the factory-built residential housing industry, originating from manufactured homes (e.g. mobile homes, is embracing emerging industry segments such as modular or panelized homes. Since indications exist that factory-built home production is slated to gain a more prominent role in the U.S. construction markets at the cost of traditional stick-built production, the factory-built home industry sub-segment is of considerable importance to the forest products industry. This research looks at manufactured home producers as a benchmark for analyzing the current economic state of the industry and discusses competitive strategies. The analysis concludes, through macroeconomic modeling, that manufactured homes are in the declining stage of their product life cycle due to changes to the U.S. residential construction sector and the factory-built home industry and by advancements of rival industry-segments. As market share continues to decline, firms operating in this industry-segment seek to either hedge their losses through product diversification strategies or remain focused on strategically repositioning the manufactured home segment.

2012-12-01

Full Text Available There are some key drivers that favor deforestation and forest degradation. Consequently, levels of carbon stock are affected in different parts of same forest types. But the problem lies in exploring the extent of the effects on level of carbon stocking. This paper highlights the variations in levels of carbon stocks in three different collaborative forests of same forest type i.e. tropical sal (Shorea robusta forest in Mahottari district of the central Terai in Nepal. Three collaborative forests namely Gadhanta-Bardibas Collaborative Forest (CFM, Tuteshwarnath CFM and Banke- Maraha CFM were selected for research site. Interview and workshops were organized with the key informants that include staffs, members and representatives of CFMs to collect the socio-economic data and stratified random sampling was applied to collect the bio-physical data to calculate the carbon stocks. Analysis was carried out using statistical tools. It was found five major drivers namely grazing, fire, logging, growth of invasive species and encroachment. It was found highest carbon 269.36 ton per ha in Gadhanta- Bardibash CFM. The findings showed that the levels of carbon stocks in the three studied CFMs are different depending on how the drivers of deforestation and forest degradation influence over them.

Open absorption heat pump for waste heat utilization in the forest industry. A study of technical and economic potential; Oeppen absorptionsvaermepump foer uppgradering av spillvaerme fraan skogsindustrin. Studie av teknisk och ekonomisk potential

Waste heat from the forest industry is mainly humid air or humid flue gases with somewhat too low dew point for direct use as district heating or for other qualified purposes. Upgrading of the temperature by heat pumps is thus often necessary for the full use of the waste heat. This study evaluates an open absorption heat, based on hygroscopic condensation. The hygroscopic condenser has the potential to replace mechanical heat pumps or conventional absorption heat pumps (based on lithium bromide) for the upgrading of heat from humid gases. The goal for the project is to evaluate technology and potential for an open absorption heat pump for heat recovery from humid gases in the forest industry. In an open heat pump the humid gas is brought in direct contact with the hygroscopic liquid (whereas a conventional heat pump uses an intermediate circuit with evaporation of water in the evaporator). The direct contact makes it possible to recover the heat at a higher temperature than the dew point of the humid gas without the use of evaporator. The target group for the study is the forest industry and its suppliers of technology and knowledge. The study has been carried out in cooperation with representatives from the forest industry and from suppliers of equipment. The study shows that the forest industry has good potential to upgrade waste heat from humid air to district heating. The waste heat can be extracted from various humid gases such as exit air from paper machines, wood driers, green liquid quenchers and flue gases from soda boilers, mesa kilns, bark-fired boilers and gas engines. Hygroscopic condensation is considered to give economic and environmental advantages compared to conventional absorption heat pumps due to much less consumption of driving heat. An interesting special case is the regeneration of the hygroscopic medium by direct contact with hot flue gases and for this application a patent application has been filed.

Changes in Species Composition in Alder Swamp Forest Following Forest Dieback

Directory of Open Access Journals (Sweden)

Remigiusz Pielech

2018-06-01

Full Text Available It is generally hypothesized that forest dieback is a characteristic of alder swamp forests (alder carrs, Alnion glutinosae alliance. Different internal and external factors may trigger this process, including human disturbance, changes in river discharge, unusually severe and prolonged flooding, terminal age of an even-aged alder forest (ca. 100–150 years and others. Although forest dieback in this type of forest may cause major changes in environmental conditions, the influence of this change on the floristic composition has not been well recognized. The study aimed to detect any possible changes in floristic variation in alder swamp forest following forest dieback. Vegetation plots in alder swamp forests affected by forest dieback were resurveyed 20 years after a previous study. PERMANOVA was used to test the significance of the compositional change and nonmetric multidimensional scaling (NMDS with passively fitted means of the Ellenberg’s Indicator Values were used to interpret its ecological meaning. In addition, different structural and diversity indices were compared, including species richness, percentage cover of vegetation layers, Shannon and Simpson diversity and evenness. Finally, we analyzed changes in the frequency of vascular plant species using Chi square tests. We recorded clear and significant compositional changes following alder swamp forest dieback. This change was most related to the gradient of moisture, followed by the gradients of light and temperature. The analysis of the individual species showed that the species of hummocks declined, while the species of hollows increased. Moreover, the current communities are dominated by some hydrophytes that were not recorded 20 years ago. Forest dieback resulted in profound changes in the hydrological regime. The observed changes are consistent with a model of cyclic succession as proposed for alder swamps. In addition, we conclude that the natural forest dynamics have to be

Wood-energy market impact on competition, procurement practices, and profitability of landowners and forest products industry in the U.S. south

International Nuclear Information System (INIS)

Conrad, Joseph L. IV.; Bolding, M. Chad; Smith, Robert L.; Aust, W. Michael

2011-01-01

Recent emphasis on producing energy from woody biomass has raised questions about the impact of a wood-energy market on the U.S. South's wood supply chain. We surveyed wood-energy facilities, fibermills, sawmills, private landowners, and government landholders to investigate the expected impact of a vibrant wood-energy market on the southern wood supply chain. Specifically, our study was designed to document potential competition for resources, wood supply chain profitability, and landowner willingness to sell timber to energy facilities. Results indicate that wood-energy facilities and traditional mills were not competing for raw material on a large scale at the time of the study, but competition is expected over the next decade. Almost 90% of fibermills reported that traditional forest industry mills should enter the wood-energy market, but most were skeptical that the new market would improve profitability. Ninety percent of responding landowners reported a willingness to sell to energy facilities if the right price is offered and all of those who had already sold timber to an energy facility were satisfied with the experience. Only 3.5% of respondents were unwilling to sell timber to an energy company, and only one of these respondents listed timber production as a primary objective, which indicates those who would not harvest timber for energy, may be unlikely to harvest timber for other purposes also. This study suggests that the southern wood supply chain is in position to profit from a wood-energy market; however, concerns remain about the coexistence of the forest products and wood-energy industries.

Full Text Available Matang Mangrove Forest is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. This research was conducted to measure the time and productivity of forest harvesting operation and also to analyze the cost and revenue of mangrove forest harvesting operation at Matang mangrove forest. This project had been carried out in cooperation with Seri Sepetang Enterprise, one of the harvesting licenses in Kuala Sepetang, Perak. Data collections were taken in every station starting from standing tree until to the Kiln-Drying jetty. The data then calculated by using the formulas of productivity and cost analysis. As the result, the productivity for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are 1.84 tan/hour, 3.82 tan/hour and 4.64 tan/hour respectively. The cost for each operation of 9 tan log volume for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are RM 56.88, RM 10.80 and RM 36.72 respectively. As the revenue, the company paid RM 260 per 9 tan of log for the in-forest operation (felling, manual skidding and loading to the ship and pay RM 80 per 9 tan for the water transportation, and they gained the net profit of RM 192.32 and RM 43.28 respectively. The average of forest harvesting operation is twice operation in a day (equal with 2 x 9-ton volume of log production a day, so they will gain a double profit. In conclusion, the forest harvesting operation is sustainably managed for supplying the raw material of charcoal industries in Matang mangrove forest. Since, they work manually and spend much energy in this forest harvesting operation, so for further study it recommends to conduct the ergonomics evaluation during forest harvesting operation at Matang Mangrove Forest.

Cost structure of and competition for forest-based biomass

International Nuclear Information System (INIS)

Lundmark, Robert

2007-01-01

Biomass has become a popular alternative to satisfy expanding energy demand and as a substitute for fossil fuels and phased-out nuclear energy in Europe. The European Union White Paper stipulates that the utilization of biomass shall increase to 1566 TWh by 2010. However it is often overlooked that the forest resources are already, to a large extent, used by the forest industries. When promoting biomass for energy generation the consequences for the forest industries also need to be considered. Sweden is an excellent case study, as there are vast quantities of forest resources, nuclear power is starting to be phased out, there are restrictions on expanding hydropower and the political desire exists to 'set an example' with respect to carbon dioxide emissions. This paper attempts to estimate and analyse the supply of two types of forest resource, namely, roundwood and harvesting residues derived from final harvesting and commercial thinnings. Two separate supply curves are estimated: one for roundwood and one for harvesting residues. The cost structure is based on an economic-engineering approach where the separate cost components are constructed from the lowest cost element into aggregates for labour, capital, materials and overhead costs for each forest resource. The results indicate an unutilized economic supply of 12 TWh of harvesting residues in Sweden. However, after these 12 TWh have been recovered it becomes more profitable to use roundwood for energy purposes than to continue extracting further amounts of harvesting residues

Energy of forest biomass in Croatia

Cupin, N.; Krivak, B.; Dundovic, J.

2005-01-01

Forest biomass is organic substance raised in forest ecosystem, consisting of trees and bushes which are used for mechanical processing and thermal use. Croatia, with 44 percent of surface under forests, has the renewable energy potential in forest biomass that could cover as much as about 50 percent of the current heating consumption. The existence of an appropriate heating consume and district heating are a prerequisite for exploitation of the mentioned potential. At the same time, heating consumption enables the utilization of cogeneration plants and the paper gives examples of such possibilities in industry, community and special facilities (sport centres, hotels, hospitals etc.). Among them, the so called 'Croatian energy absurdum' is mentioned. The paper underlines the feasibility of exploitation of forest biomass at the national level and suggests that, in order to promote and accelerate the development of cogeneration plants, the HED expert group should be established. The task of the expert group would be to draft proposal for appropriate measures in this regard and submit it to the Government for consideration.(author)

Estimating the carbon budget and maximizing future carbon uptake for a temperate forest region in the U.S.

Science.gov (United States)

2012-01-01

Background Forests of the Midwest U.S. provide numerous ecosystem services. Two of these, carbon sequestration and wood production, are often portrayed as conflicting. Currently, carbon management and biofuel policies are being developed to reduce atmospheric CO2 and national dependence on foreign oil, and increase carbon storage in ecosystems. However, the biological and industrial forest carbon cycles are rarely studied in a whole-system structure. The forest system carbon balance is the difference between the biological (net ecosystem production) and industrial (net emissions from forest industry) forest carbon cycles, but to date this critical whole system analysis is lacking. This study presents a model of the forest system, uses it to compute the carbon balance, and outlines a methodology to maximize future carbon uptake in a managed forest region. Results We used a coupled forest ecosystem process and forest products life cycle inventory model for a regional temperate forest in the Midwestern U.S., and found the net system carbon balance for this 615,000 ha forest was positive (2.29 t C ha-1 yr-1). The industrial carbon budget was typically less than 10% of the biological system annually, and averaged averaged 0.082 t C ha-1 yr-1. Net C uptake over the next 100-years increased by 22% or 0.33 t C ha-1 yr-1 relative to the current harvest rate in the study region under the optized harvest regime. Conclusions The forest’s biological ecosystem current and future carbon uptake capacity is largely determined by forest harvest practices that occurred over a century ago, but we show an optimized harvesting strategy would increase future carbon sequestration, or wood production, by 20-30%, reduce long transportation chain emissions, and maintain many desirable stand structural attributes that are correlated to biodiversity. Our results for this forest region suggest that increasing harvest over the next 100 years increases the strength of

Being used to the practiced processing of raw materials for many decades the industry had to tap the advantage of renewable raw materials again. Conventional processing methods had to be changed and to be newly developed. This has been a rewarding task considering the ecological advantages but also considering the interesting markets for products based upon renewable raw materials. Today the German industry above all the chemical industry again processes agricultural and forestal raw materials to a considerable extent. Ten percent of the raw materials processed by the chemical industry are renewable. The wood processing industry is an important economic sector that achieves a value creation with the raw material wood exceeding the value creation of other industries by far. This brochure gives an overview of the possible substances, which are processed from renewable raw materials in Germany and it shows the important role that agricultural raw materials and wood already play for the industry nowadays.

incentives to clear natural forests through CDM crediting for afforestation and reforestation, we recommend for the first commitment period that policymakers establish an early base year, such as 1990, such that lands cleared after that year would be ineligible for crediting. We further recommend an exception to this rule for CDM projects that are explicitly designed to promote natural forest restoration and that pass rigorous environmental impact review. Restoration efforts are typically most effective on lands that are adjacent to standing forests and hence likely to have been recently cleared. Thus, we recommend for these projects establishing a more recent base year, such as 2000. For the second and subsequent commitment periods, we recommend that climate policymakers act to restrain inter-annex leakage and its impacts by ensuring that crediting for forest management in industrialized countries is informed by modelling efforts to anticipate the scale of leakage associated with different Annex I 'Land use, land-use change and forestry' policy options, and coupled with effective measures to protect natural forests in developing countries. The latter should include expanding the options permitted under the CDM to carbon crediting for projects that protect threatened forests from deforestation and forest degradation. Ultimately, carbon market incentives for forest clearing can be reduced and incentives for forest conservation most effectively strengthened by fully capturing carbon emissions associated with deforestation and forest degradation in developing countries under a future emissions cap. Finally, we note that these recommendations have broader relevance to any forest-based measures to reduce greenhouse-gas emissions developed outside of the specific context of the Kyoto Protocol.

Vulnerability of the boreal forest to climate change: are managed forests more susceptible?

International Nuclear Information System (INIS)

Leduc, A.; Gauthier, S.

2004-01-01

This paper postulates that forests dominated by younger seral stages are less vulnerable to climate change that those composed of mature and overmature stands. To support this analysis, an overview of expected changes in climate conditions was provided. Expected changes include higher maximum temperatures, higher minimum temperatures and a decrease in periods of intense cold and fewer frost days; reduction in the diurnal temperature range; an increase in the apparent heat index; greater numbers of intense precipitation; and, increased risk of drought associated with air mass movements. A comparison between conditions in a managed forest mosaic and natural forests was made, with managed forests differing due to efforts to regulate the age structure. The inversion in the age structure of forest mosaics creates significant changes in structural characteristics and composition, including greater hardwood components and more even-aged stands. It was concluded that in Canada, managed boreal forests are younger and have less black spruce and more hardwoods and fir, making younger forests less vulnerable to fire and more amenable to fire control due to increased accessibility. It was also noted that because of their relative youth, managed forests are more vulnerable to regeneration failure and that managed forests with more balsam fir and trembling aspen are at greater risk for insect outbreaks. In addition, wind throw, a threat to older forests, is not significant in managed forests. 15 refs., 1 tab., 2 figs

Interactions among Amazon land use, forests and climate: prospects for a near-term forest tipping point.

Some model experiments predict a large-scale substitution of Amazon forest by savannah-like vegetation by the end of the twenty-first century. Expanding global demands for biofuels and grains, positive feedbacks in the Amazon forest fire regime and drought may drive a faster process of forest degradation that could lead to a near-term forest dieback. Rising worldwide demands for biofuel and meat are creating powerful new incentives for agro-industrial expansion into Amazon forest regions. Forest fires, drought and logging increase susceptibility to further burning while deforestation and smoke can inhibit rainfall, exacerbating fire risk. If sea surface temperature anomalies (such as El Niño episodes) and associated Amazon droughts of the last decade continue into the future, approximately 55% of the forests of the Amazon will be cleared, logged, damaged by drought or burned over the next 20 years, emitting 15-26Pg of carbon to the atmosphere. Several important trends could prevent a near-term dieback. As fire-sensitive investments accumulate in the landscape, property holders use less fire and invest more in fire control. Commodity markets are demanding higher environmental performance from farmers and cattle ranchers. Protected areas have been established in the pathway of expanding agricultural frontiers. Finally, emerging carbon market incentives for reductions in deforestation could support these trends.

Global change is impacting forests worldwide, threatening biodiversity and ecosystem services, including climate regulation. Understanding how forests respond is critical to forest conservation and climate protection. This review describes an international network of 59 long-term forest dynamic research sites useful for characterizing forest responses to global change. The broad suite of measurements made at the CTFS-ForestGEO sites make it possible to investigate the complex ways in which global change is impacting forest dynamics. ongoing research across the network is yielding insights into how and why the forests are changing, and continued monitoring will provide vital contributions to understanding worldwide forest diversity and dynamics in a era of global change

The relationship between human beings and forests has been important for the development of society. It is based on various productive, ecological, social and cultural functions of forests. The cultural functions, including the spiritual and symbolic role of forests, are often not addressed...... with the same attention as the other functions. The aim of this paper is to put a stronger emphasis on the fact that the acknowledgement of cultural bonds is needed in the discussion of sustainable development. Forest should not only be considered as a technical means to solve environmental and economic...... problems. To achieve a deeper understanding of the dependency of society on forests, it is necessary to recognise the role of forests in our consciousness of being human. Giving a historical overview about the cultural bonds between people and forests, the first part of the paper puts focus on non...

Forests often rebound from deforestation following industrialization and urbanization, but for many regions our understanding of where and when forest transitions happened, and how they affected carbon budgets remains poor. One such region is Eastern Europe, where political and socio......-economic conditions changed drastically over the last three centuries, but forest trends have not yet been analyzed in detail. We present a new assessment of historical forest change in the European part of the former Soviet Union and the legacies of these changes on contemporary carbon stocks. To reconstruct forest...... carbon stock dynamics. Our results revealed that forest transitions in Eastern Europe occurred predominantly in the early 20th century, substantially later than in Western Europe. We also found marked geographic variation in forest transitions, with some areas characterized by relatively stable...

Harvesting Carbon from Eastern US Forests: Opportunities and Impacts of an Expanding Bioenergy Industry

Directory of Open Access Journals (Sweden)

Sarah C. Davis

2012-06-01

Full Text Available Eastern forests of the US are valued both as a carbon sink and a wood resource. The amount of biomass that can be harvested sustainably from this biome for bioenergy without compromising the carbon sink is uncertain. Using past literature and previously validated models, we assessed four scenarios of biomass harvest in the eastern US: partial harvests of mixed hardwood forests, pine plantation management, short-rotation woody cropping systems, and forest residue removal. We also estimated the amount and location of abandoned agricultural lands in the eastern US that could be used for biomass production. Greater carbon storage was estimated to result from partial harvests and residue removals than from plantation management and short-rotation cropping. If woody feedstocks were cultivated with a combination of intensive management on abandoned lands and partial harvests of standing forest, we estimate that roughly 176 Tg biomass y⁻¹ (~330,000 GWh or ~16 billion gallons of ethanol could be produced sustainably from the temperate forest biome of the eastern US. This biomass could offset up to ~63 Tg C y⁻¹ that are emitted from fossil fuels used for heat and power generation while maintaining a terrestrial C sink of ~8 Tg C y⁻¹.

Full Text Available The review presents data on 23 rare species of the Central Forest Reserve included in the Red Data Book of the Russian Federation. The state of their populations (groups of populations is assessed. The characteristics of landscape and coenotic confinement are given. Their biological and ecological features are briefly described, and the limiting factors determining the reduction in the number of some species are indicated. Over 85 years, many species have remained their biological positions in the Reserve, and their quantity has remained stable. At the same time, species of sedentary birds (Bubo bubo, Lagopus lagopus rossicus and birds nesting in the Protected Area (representatives of the Accipitridae family are now few in number due to the changes in the main habitats and deterioration of the forage resources. It is noted that the Central Forest Reserve is the largest Protected Area in Central Russia for the rare lichens Lobaria pulmonaria and Menegazzia terebrata.

Environmental concerns gaining importance in industry operations

This paper reports that environmental concerns have leapt to the forefront of industry's concerns in operating in Latin America. The United Nations Conference on Environment and Development in Rio de Janeiro June 3-14 focused a strong world spotlight on the region's environmental and commercial resources. Protection of the region's rain forests, which accounts for a huge share of the world's total, is emerging as an especially contentious issue. Ecuador's Oriente region may well prove the litmus test of how or whether oil and gas companies are able to operate in Latin American rain forests. Controversy over industry operations in the Oriente have heated to the point that environmentalist and native groups have routinely picketed company offices in Quito and used mass fundraiser mailings in North America

Indonesia and Malaysia have emerged as leading producers of palm oil in the past several decades, expanding production through the conversion of tropical forests to industrial plantations. Efforts to produce "sustainable" palm oil, including certification by the Roundtable on Sustainable Palm Oil (RSPO), include guidelines designed to reduce the environmental impact of palm oil production. Fire-driven deforestation is prohibited by law in both countries and a stipulation of RSPO certification, yet the degree of environmental compliance isunclear, especially during El Niño events when drought conditions increase fire risk. Here, we used time series of satellite data to estimate the spatial and temporal patterns of fire-driven deforestation on and around oil palm plantations. In Indonesia, fire-driven deforestation accounted for one-quarter of total forest losses on both certified and noncertified plantations. After the first plantations in Indonesia received RSPO certification in 2009,forest loss and fire-driven deforestation declined on certified plantations but did not stop altogether. Oil palm expansion in Malaysia rarely involved fire; only 5 % of forest loss on certified plantations had coincident activefire detections. Interannual variability in fire detections was strongly influenced by El Nino and the timing of certification. Fire activity during the 2002, 2004, and 2006 El Nino events was similar among oil palm plantations in Indonesia that would later become certified, noncertified plantations, and surrounding areas. However, total fire activity was 75% and 66% lower on certified plantations than noncertified plantations during the 2009 and 2015 El Nino events, respectively. The decline in fire activity on certified plantations, including during drought periods, highlights the potential for RSPO certification to safeguard carbon stocks in peatlands and remaining forests in accordance with legislation banning fires. However, aligning certification

Extreme differences in forest degradation in Borneo: comparing practices in Sarawak, Sabah, and Brunei.

Directory of Open Access Journals (Sweden)

Jane E Bryan

Full Text Available The Malaysian states of Sabah and Sarawak are global hotspots of forest loss and degradation due to timber and oil palm industries; however, the rates and patterns of change have remained poorly measured by conventional field or satellite approaches. Using 30 m resolution optical imagery acquired since 1990, forest cover and logging roads were mapped throughout Malaysian Borneo and Brunei using the Carnegie Landsat Analysis System. We uncovered ∼364,000 km of roads constructed through the forests of this region. We estimated that in 2009 there were at most 45,400 km(2 of intact forest ecosystems in Malaysian Borneo and Brunei. Critically, we found that nearly 80% of the land surface of Sabah and Sarawak was impacted by previously undocumented, high-impact logging or clearing operations from 1990 to 2009. This contrasted strongly with neighbouring Brunei, where 54% of the land area remained covered by unlogged forest. Overall, only 8% and 3% of land area in Sabah and Sarawak, respectively, was covered by intact forests under designated protected areas. Our assessment shows that very few forest ecosystems remain intact in Sabah or Sarawak, but that Brunei, by largely excluding industrial logging from its borders, has been comparatively successful in protecting its forests.

This paper presents the detection of Angsi and Berembun Reserve Forest change for years 1996 and 2013. Forest is an important part of our ecosystem. The main function is to absorb carbon oxide and produce oxygen in their cycle of photosynthesis to maintain a balance and healthy atmosphere. However, forest changes as time changes. Some changes are necessary as to give way for economic growth. Nevertheless, it is important to monitor forest change so that deforestation and development can be planned and the balance of ecosystem is still preserved. It is important because there are number of unfavorable effects of deforestation that include environmental and economic such as erosion of soil, loss of biodiversity and climate change. The forest change detection can be studied with reference of several satellite images using remote sensing application. Forest change detection is best done with remote sensing due to large and remote study area. The objective of this project is to detect forest change over time and to compare forest health indicated by Normalized Difference Vegetation Index (NDVI) using remote sensing and image processing. The forest under study shows depletion of forest area by 12% and 100% increment of deforestation activities. The NDVI value which is associated with the forest health also shows 13% of reduction

Harvesting Adaptation to Biodiversity Conservation in Sawmill Industry: Technology Innovation and Monitoring Program

2007-09-01

Full Text Available Social demands related to native forest ecosystems are based on an efficient management, with a balance between conservation and timber production. This paper describes the industry adaptation to a biodiversity program with an alternative regeneration method. The proposed method leaves 30% of the timber-quality forest as aggregated retention and 15 m² ha-1 basal area as dispersed retention. While many costs increased considerably, the incomes also may increase by applying new management strategies and technology innovation. A monitoring program was established in the harvested stands to evaluate the ecological functionality of the applied regeneration system (forest structure, climate change, regeneration dynamics, habitat quality and abiotic cycles. The implementation of an innovated technology and monitoring program in the forest and industry determined a balance between economic values and biodiversity conservation.

Managing the world's forests.

Science.gov (United States)

Sharma, N; Rowe, R

1992-06-01

Forests play a vital role in balancing natural systems: the stabilization of global climate and the management of water and land. 30% of the earth's total land area is forested. 66% of the tropical moist forests are in Latin America and the remainder in Africa and Asia. 75% of tropical dry forests are in Africa. Temperate forests are primarily in developed countries. Deforestation and misuse of forests occurs primarily in developing countries at significant social, economic, and environmental costs. Losses have occurred in fuelwood, fodder, timber, forest products, biological diversity, habitats, genetic materials for food and medicine. The World Bank's evolving role in forestry is briefly described. Agreement has not been reached among people or nations about the most appropriate means to balance conservation and development goals. The challenge is to stabilize existing forests and increase forest planting. The causes of forest degradation must be understood. Direct causes include agricultural encroachment, cattle ranching, fuelwood gathering, commercial logging, and infrastructure development. These direct causes are driven by economic, social, and political forces: market and policy failures, population growth, and poverty. The market failures include: 1) the lack of clearly defined property rights on forest resources for now and the future, 2) the conflict between individual and societal needs, 3) the difficulty in placing a value on nonmarket environmental services and joint products, and 4) the separation between private and social costs. The solution is action at the local, national, and global levels. Countries must establish forest policy. The existing government incentives which promote deforestation must be changed. For example, concession policy and royalty systems must be corrected; explicit and implicit export subsidies on timber and forest products must be stopped. Private incentives must be established to promote planting of trees, practicing

Trace metal inventories and lead isotopic composition chronicle a forest fire's remobilization of industrial contaminants deposited in the angeles national forest.

The amounts of labile trace metals: [Co] (3 to 11 µg g-1), [Cu] (15 to 69 µg g-1), [Ni] (6 to 15 µg g-1), [Pb] (7 to 42 µg g-1), and [Zn] (65 to 500 µg g-1) in ash collected from the 2012 Williams Fire in Los Angeles, California attest to the role of fires in remobilizing industrial metals deposited in forests. These remobilized trace metals may be dispersed by winds, increasing human exposures, and they may be deposited in water bodies, increasing exposures in aquatic ecosystems. Correlations between the concentrations of these trace metals, normalized to Fe, in ash from the fire suggest that Co, Cu, and Ni in most of those samples were predominantly from natural sources, whereas Pb and Zn were enriched in some ash samples. The predominantly anthropogenic source of excess Pb in the ash was further demonstrated by its isotopic ratios (208Pb/207Pb: 206Pb/207Pb) that fell between those of natural Pb and leaded gasoline sold in California during the previous century. These analyses substantiate current human and environmental health concerns with the pyrogenic remobilization of toxic metals, which are compounded by projections of increases in the intensity and frequency of wildfires associated with climate change.

2017-01-01

After the accident at the Fukushima Daiichi Nuclear Power Station (FDNPS) in 2011, the residential areas within the evacuation order areas around FDNPS were extensively decontaminated, but the need for forest decontamination remains controversial. Almost 70% of Fukushima prefecture is covered by forest, and forestry is one of the key industries there. From the perspective of forestry recovery and environmental preservation, Fukushima residents desire the further decontamination of forests; from the perspective of cost-effectiveness and priorities, however, this has both pros and cons(1). Bearing in mind the need to discuss priorities regarding the decontamination of forest, therefore, a radiation dose evaluation of foresters working in the FDNPS vicinity is important. This paper reports on the measurement of individual radiation doses by occupation in Kawauchi village (Figure 1a), which is located within 30 km from the FDNPS(2, 3), using the personal dosimeter (D-Shuttle"R, Chiyoda Technol Corp, Tokyo, Japan). Our results showed that estimated annual doses of 1.19 mSv/year (median) with a range of 0.71 1.89 among foresters, 0.97 (0.66 1.48) mSv/year for farmers, 0.94 (0.59 1.51) mSv/year for builders, 0.88 (0.54 1.48) mSv/year for officers, 1.01 (0.55 1.75) mSv/year for unemployed individuals and 0.98 (0.54 7.07) mSv/ year for decontamination workers (Figure 1b). Thus, the annual doses of foresters was not significantly higher than farmers, builders, officers and unemployed individuals, whereas those of decontamination workers were significantly higher than for other workers, including foresters, suggesting that in terms of protecting foresters from radiation, forest decontamination is not a high-priority policy in Fukushima. The International Commission on Radiological Protection (ICRP) recommends that for the protection of residents living in radio-contaminated areas during the recovery process, the justification of protection strategies goes far beyond the scope

During the year 2000, The Swedish Forest Administration and Forest Department, Ministry of Environment in Lithuania, started a bilateral co-operation project, named: 'Swedish Lithuanian Wood Fuel Development Project', financed by the Swedish Energy Agency. The project was divided into 2 phases. The first phase objectives were to make a feasibility study in the eastern part of Lithuania and to identify the present conditions for the utilization of wood fuel within seven state forest enterprises and to define a demonstration and experimental area for the phase 2. The purpose of this work was to find solutions for creating horizontal and vertical integration in the handling of forest fuels in ordinary forestry and supply systems. The aim would be to give specific recommendations on which methods are the most suitable and profitable and on what type of equipment to use for various conditions and by the means of demonstrations to show how to integrate the positive results into the ordinary forestry activities. Different kinds of activities have been carried out to ensure capacity building and development on other levels within the system. 3 activity groups were established and have been working side by side with the appointed team leaders for each activity group from the institutions leading in the specific area within the forest sector in Lithuania. Swedish specialists from the Swedish Forest Administration were involved into the project and the activity groups as well. Lithuanian Forest Research Institute was involved into the project with research support. Additional to the project a mobile drum wood chipper was purchased from Sweden. 3 separate investigations have been conducted, one by Kaunas Univ. of Tech. on the analysis and estimation of material balance in Lithuania saw milling industry, another by Forest Economy Centre on wood fuel produced in industry in Lithuania and the third one by Lithuanian Energy Institute and AF international on Bio fuel

The paper presents a succinct history of Russian forests during the time period of 1960-2010 and reanalysis of their impacts on global carbon and nitrogen cycles. We present dynamics of land cover change (including major categories of forest land) and biometric characteristics of forests (species composition, age structure, growing stock volume etc.) based on reconciling all relevant information (data of forest and land inventories, official forest management statistics, multi-sensor remote sensing products, data of forest pathological monitoring etc.). Completeness and reliability of background information was different during the period of the study. Forest inventory data and official statistics were partially modified based on relevant auxiliary information and used for 1960-2000. The analysis for 2001-2010 was provided with a crucial use of multi-sensor remote sensing data. For this last period a hybrid forest mask was developed at resolution of 230m by integration of 8 remote sensing products and using geographical weighted regression and data of crowdsourcing. During the considered 50 years forested areas of Russia substantially increased by middle of 1990s and slightly declined (at about 5%) after. Indicators needed for assessment of carbon and nitrogen cycles of forest ecosystems were defined for the entire period (aggregated estimates by decades for 1960-2000 and yearly for 2001-2010) based on unified methodology with some peculiarities following from availability of information. Major results were obtained by landscape-ecosystem method that uses as comprehensive as possible empirical and semi-empirical information on ecosystems and landscapes in form of an Integrated Land Information System and complimentary combines pool- and flux-based methods. We discuss and quantify major drivers of forest cover change (socio-economic, environmental and climatic) including forest management (harvest, reforestation and afforestation), impacts of seasonal weather on

Accurate and spatially-explicit maps of tropical forest carbon stocks are needed to implement carbon offset mechanisms such as REDD+ (Reduced Deforestation and Degradation Plus). The Random Forest machine learning algorithm may aid carbon mapping applications using remotely-sensed data. However, Random Forest has never been compared to traditional and potentially more reliable techniques such as regionally stratified sampling and upscaling, and it has rarely been employed with spatial data. Here, we evaluated the performance of Random Forest in upscaling airborne LiDAR (Light Detection and Ranging)-based carbon estimates compared to the stratification approach over a 16-million hectare focal area of the Western Amazon. We considered two runs of Random Forest, both with and without spatial contextual modeling by including--in the latter case--x, and y position directly in the model. In each case, we set aside 8 million hectares (i.e., half of the focal area) for validation; this rigorous test of Random Forest went above and beyond the internal validation normally compiled by the algorithm (i.e., called "out-of-bag"), which proved insufficient for this spatial application. In this heterogeneous region of Northern Peru, the model with spatial context was the best preforming run of Random Forest, and explained 59% of LiDAR-based carbon estimates within the validation area, compared to 37% for stratification or 43% by Random Forest without spatial context. With the 60% improvement in explained variation, RMSE against validation LiDAR samples improved from 33 to 26 Mg C ha(-1) when using Random Forest with spatial context. Our results suggest that spatial context should be considered when using Random Forest, and that doing so may result in substantially improved carbon stock modeling for purposes of climate change mitigation.

In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in FY95 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven `Vision Industries` that use about 80% of industrial energy and generated about 90% of industrial wastes. These are: aluminium; chemical; forest products; glass; metal casting; refineries; and steel. OIT is working with these industries, through appropriate organizations, to develop Visions of the desired condition of each industry some 20 to 25 years in the future and then to prepare Road Maps and Implementation Plans to enable them to reach their goals. The mission of AIM has, therefore, changed to `Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`

Determination of Dioxins in Soil Samples from industrial and burned forest sites in Syria Using an Enzyme Linked Immunosorbent Assay (ELIZA)

International Nuclear Information System (INIS)

Ghanem, I.; Orfi, M.; Abu-Alnaser, A.

2013-01-01

Sixty soil samples were collected from three industrial locations and burnt forest locution of Syria, namely, Banyas refinery and the Thermal Electricity Generation Station area (7 samples), Central factory area, Tartous (11 samples), AlFrunlok Forest, Lattakia (22 samples), Alwaer and Oil refinery area in Homs (20 samples) Dioxin presence in these samples was determined using a specific ELIZA Kit, Results indicate the absence of any detectable levels of Dioxins from any of the samples collected in Banyas refinery, Electricity Generation Station of Banyas, Central factory and the area of Hsain AlBaher, Mazrahat AlArous in Tartous. Likewise, all samples (22 samples) taken from AlFrunlok forest area were free of Dioxin contamination except the samples taken from the road to Nubu Issa, and Shahrura, where 8 samples (36.36%) and 6 samples (27.27%) contained concentration of Dioxin ranging between 5-15 and 15-25 PPT respectively. Results showed the presence of Dioxins in samples collected at AlWa-er area, Homs (17 sample) at high concentration in comparison with samples collected in other areas. Three of those samples (17.6%) and four samples (23.5%) contained Dioxins at levels ranging between 15-25 and 15-25 PPT respectively. (58.8%) of all samples (10 samples) collected in this area, contained Dioxins at levels exceeding the maximum level detectable by the ELIZA kit (i.e. 50 PPT). The results reported in the present study justify a follow up and detailed study in AlWa-er area. (author)

Ecological restoration of peatlands in steppe and forest-steppe areas

Minayeva, Tatiana; Sirin, Andrey; Dugarjav, Chultem

2016-04-01

Peatlands in the arid and semi-arid regions of steppe and forest steppe belt of Eurasia have some specific features. That demands the special approach to their management and restoration. The distribution of peatlands under conditions of dry climate is very limited and they are extremely vulnerable. Peatlands in those regions are found in the highlands where temperate conditions still present, in floodplains where they can get water from floods and springs, or in karst areas. Peatlands on watersheds present mainly remains from the more humid climate periods. Water and carbon storage as well as maintenance of the specific biodiversity are the key ecosystem natural functions of peatlands in the steppe and forest steppe. The performance of those functions has strong implications for people wellness and livelihood. Anyhow, peatlands are usually overlooked and poorly represented in the systems of natural protected areas. Land management plans, mitigation and restoration measures for ecosystems under use do not usually include special measures for peatlands. Peatlands'use depends on the traditional practices. Peat extraction is rather limited in subhumid regions but still act as one of the threats to peatlands. The most of peatlands are used as pastures and grasslands. In densely populated areas large part of peatlands are transformed to the arable lands. In many cases peatlands of piedmonts and highlands are affected by industrial developments: road construction, mining of subsoil resources (gold, etc.). Until now, the most of peatlands of steppe and forest steppe region are irreversibly lost, what also effects water regime, lands productivity, biodiversity status. To prevent further dramatic changes the ecological restoration approach should be introduced in the subhumid regions. The feasibility study to assess the potential for introducing ecological restoration techniques for peatlands in the arid and semi-arid conditions had been undertaken in steppe and forest

New plantations can either cause deforestation by replacing natural forests or avoid this by using previously cleared areas. The extent of these two situations is contested in tropical biodiversity hotspots where objective data are limited. Here, we explore delays between deforestation and the establishment of industrial tree plantations on Borneo using satellite imagery. Between 1973 and 2015 an estimated 18.7 Mha of Borneo’s old-growth forest were cleared (14.4 Mha and 4.2 Mha in Indonesian and Malaysian Borneo). Industrial plantations expanded by 9.1 Mha (7.8 Mha oil-palm; 1.3 Mha pulpwood). Approximately 7.0 Mha of the total plantation area in 2015 (9.2 Mha) were old-growth forest in 1973, of which 4.5-4.8 Mha (24-26% of Borneo-wide deforestation) were planted within five years of forest clearance (3.7-3.9 Mha oil-palm; 0.8-0.9 Mha pulpwood). This rapid within-five-year conversion has been greater in Malaysia than in Indonesia (57-60% versus 15-16%). In Indonesia, a higher proportion of oil-palm plantations was developed on already cleared degraded lands (a legacy of recurrent forest fires). However, rapid conversion of Indonesian forests to industrial plantations has increased steeply since 2005. We conclude that plantation industries have been the principle driver of deforestation in Malaysian Borneo over the last four decades. In contrast, their role in deforestation in Indonesian Borneo was less marked, but has been growing recently. We note caveats in interpreting these results and highlight the need for greater accountability in plantation development.

SO/sub 2/ injury to forests

Energy Technology Data Exchange (ETDEWEB)

Hontvedt, R

1970-01-01

Sulfur dioxide is one of the most important of the air pollutants which has produced damage to trees and other vegetation. This article gives some examples of SO/sub 2/ damage to forests: At Rjukan in Norway, at Naerkes-Kvarntorp in Sweden and in German industrial regions. Then a brief summary is given of the factors which determine the effects of SO/sub 2/ on plants. Significant differences in SO/sub 2/ resistance exist, both between species and between individuals of the same species. Deciduous trees are more resistant than conifers. There appears to be a positive correlation between CO/sub 2/ assimilation and SO/sub 2/ damage in some individuals. Factors which influence co2 assimilation include, for example, the leaf development state and environmental factors (light, water, temperature, etc.). High SO/sub 2/ concentrations in the air over a brief time period are distinctly more injurious than low concentrations over a long time. Fertilization may increase the resistance of forest trees to SO/sub 2/. Some insect types predispose to SO/sub 2/, partly by increasing the number of dead and weakened trees and partially by increasing parasitization by insects.

Full Text Available Turkey should benefit from its own resources by realizing their value in the period that it turned its face to Europe. Therefore, the economical potential of the country should be analyzed thoroughly. Knowing its own strength and taking the necessary steps to this effect in order to take the fullest advantage of the strength are of vital importance for the countries in attaining the development level. Within the existing potential, the necessary importance and support should be given to small and medium enterprises that are forming the most effective part of the economic life and to the forest products industry which has a significant position among these enterprises. In this study, certain product groups belonging to paper and paperboard industry situated in forest products industry were discussed what situation they are in Turkey and European Union countries and competition position. In this context, hierarchical cluster analysis and discriminant analysis being of multidimensional statistical methods were used.

Fire regime in a Mexican forest under indigenous resource management.

2011-04-01

The Rarámuri (Tarahumara) people live in the mountains and canyons of the Sierra Madre Occidental of Chihuahua, Mexico. They base their subsistence on multiple-use strategies of their natural resources, including agriculture, pastoralism, and harvesting of native plants and wildlife. Pino Gordo is a Rarámuri settlement in a remote location where the forest has not been commercially logged. We reconstructed the forest fire regime from fire-scarred trees, measured the structure of the never-logged forest, and interviewed community members about fire use. Fire occurrence was consistent throughout the 19th and 20th centuries up to our fire scar collection in 2004. This is the least interrupted surface-fire regime reported to date in North America. Studies from other relict sites such as nature reserves in Mexico or the USA have all shown some recent alterations associated with industrialized society. At Pino Gordo, fires recurred frequently at the three study sites, with a composite mean fire interval of 1.9 years (all fires) to 7.6 years (fires scarring 25% or more of samples). Per-sample fire intervals averaged 10-14 years at the three sites. Approximately two-thirds of fires burned in the season of cambial dormancy, probably during the pre-monsoonal drought. Forests were dominated by pines and contained many large living trees and snags, in contrast to two nearby similar forests that have been logged. Community residents reported using fire for many purposes, consistent with previous literature on fire use by indigenous people. Pino Gordo is a valuable example of a continuing frequent-fire regime in a never-harvested forest. The Rarámuri people have actively conserved this forest through their traditional livelihood and management techniques, as opposed to logging the forest, and have also facilitated the fire regime by burning. The data contribute to a better understanding of the interactions of humans who live in pine forests and the fire regimes of these

The implications of new forest tenure reforms and forestry property markets for sustainable forest management and forest certification in China.

Science.gov (United States)

Chen, Juan; Innes, John L

2013-11-15

This study examines issues existing in the southern collective forests in China, particularly prior to the implementation of new forest tenure reforms, such as continued illegal logging and timber theft, inadequate availability of finance and inconsistent forest-related policies. Such problems are believed to be hindering the adoption of sustainable forest management (SFM) and forest certification by forest farmers in China. Two strategies were introduced by the Chinese government with the purpose of addressing these issues, namely forest tenure reforms and their associated supporting mechanism, forestry property markets. Through two case studies in southern China, we investigated the effectiveness of the two strategies as well as their implications for the adoption of SFM and forest certification. The two cases were Yong'an in Fujian province and Tonggu in Jiangxi province. Personal interviews with open-ended questions were conducted with small-scale forest farmers who had already benefited from the two strategies as well as market officers working for the two selected forestry property markets. The study identified eight issues constraining the potential adoption of SFM and certification in China, including limited finance, poorly developed infrastructure and transport systems, insecure forest tenures, inconsistent forest policies, low levels of awareness, illegal forest management practices, lack of local cooperative organizations, and inadequate knowledge and technical transfer. We found that the new forest tenure reforms and forestry property markets had generally fulfilled their original objectives and had the capacity to assist in addressing many of the issues facing forests prior to the reforms.

Flux and concentration processes of radioactive elements in the forest industry; dosimetry, biofueled heating plants, the alkaline and the acidic pulp mill processes

International Nuclear Information System (INIS)

Ravila, A.; Holm, E.

1992-01-01

A fraction of the radionuclides released to the forest ecosystem will be incorporated into different parts of the trees and the wood. A common factor for both biofueled power plants and pulp mills is that they concentrate the radionuclides initially present in the in the biofuel or wood in ashes or other products. The enrichment of radioactive elements is due to the combustion process or in a pulp mill, the combustion of bark and liquors, and also the processes in the pulp mill recycling system. The radiological impacts to man from forest industry arises form radiation emitted from the radionuclides present in ash and pulp mill liquors and liquor sludge. The quantification and calculation of past, present and future activity concentrations in biofuels, ash and pulp mill waste products are all important when assessments of the radiation dose is done. In order to assess the resulting dose to staff working close to radionuclide containing recycling systems and waste dumps, it is necessary to know the dynamics (inflow rate and residence time) of the radionuclides in that system

Trace Metal Inventories and Lead Isotopic Composition Chronicle a Forest Fire’s Remobilization of Industrial Contaminants Deposited in the Angeles National Forest

Odigie, Kingsley O.; Flegal, A. Russell

2014-01-01

The amounts of labile trace metals: [Co] (3 to 11 µg g−1), [Cu] (15 to 69 µg g−1), [Ni] (6 to 15 µg g−1), [Pb] (7 to 42 µg g−1), and [Zn] (65 to 500 µg g−1) in ash collected from the 2012 Williams Fire in Los Angeles, California attest to the role of fires in remobilizing industrial metals deposited in forests. These remobilized trace metals may be dispersed by winds, increasing human exposures, and they may be deposited in water bodies, increasing exposures in aquatic ecosystems. Correlations between the concentrations of these trace metals, normalized to Fe, in ash from the fire suggest that Co, Cu, and Ni in most of those samples were predominantly from natural sources, whereas Pb and Zn were enriched in some ash samples. The predominantly anthropogenic source of excess Pb in the ash was further demonstrated by its isotopic ratios (208Pb/207Pb: 206Pb/207Pb) that fell between those of natural Pb and leaded gasoline sold in California during the previous century. These analyses substantiate current human and environmental health concerns with the pyrogenic remobilization of toxic metals, which are compounded by projections of increases in the intensity and frequency of wildfires associated with climate change.

Energy conservation in pulp and paper industry: some thoughts

Energy Technology Data Exchange (ETDEWEB)

Sadawarte, N. S.; Prasad, A. K.; Khanolkar, V. D.; Shenoy, S. C.

1980-03-15

The pulp and paper industry is highly energy intensive. In view of the spiralling fuel prices and rising power costs, there is an urgent need to conserve energy through better management of various operations in the industry, from the optimal utilization of the forest residues to the shipment of the final product. The total energy concept, e.g., energy generation, distribution and utilization in Indian paper industry is discussed. The need for an energy audit is emphasized and the formats of energy reporting forms are included. Short and long term measures to be enforced to achieve energy savings in the pulp and paper mills are outlined. Some important energy conservation approaches are also discussed. Factors affecting energy efficiency in a pulp and paper mill are reviewed. Some areas where sustained R and D efforts should be focused to make the paper industry nearly self-sufficient in energy generation and utilization are also given. It is essential to have a National Energy Policy clearly defining achievable targets of energy conservation for industry. The Indian paper industry could advantageously form its own committee to review the operation of the various mills in the country and come out with concrete solutions for higher energy efficiency and more effective conservation of energy.

Water cycle observations in forest watersheds of Cambodia

The Lower Mekong River flows through Cambodia, where forests cover ~60% of the country and are believed to have a marked effect on the water cycle. These tropical seasonal forests in the Cambodian flat lands are very precious in the Indochinese Peninsula as few forests of this type remain. However, few hydrological observations have been conducted in these areas. In Cambodia, deciduous and evergreen forests make up 42% and 33% of the total forest area, respectively. We established experimental watersheds both in deciduous and evergreen forests containing meteorological observation towers in Cambodia and collected various observational data since 2003 (O'Krieng, deciduous forest watershed including a 30-m-high observation tower, 2,245 km2; Stung Chinit, evergreen forest watershed including a 60-m-high observation tower, 3,700 km2 including three small watersheds). The basic data from these sites included various kinds of information related to the composition of vegetation, soil characteristics, etc. Hydrologic data was collected and linked to the above data; the main hydrologic research results follow. The water budget for each watershed was determined using an observational rainfall and runoff dataset. The evapotranspiration rate in an evergreen forest was obtained using various observational methods including the Bowen energy-balance ratio and the bandpass eddy covariance method. The annual evapotranspiration of evergreen forests, estimated using the Bowen energy-balance ratio method and water balance, was about 1100-1200 mm, corresponding to 70-80% of annual rainfall. While considering the importance of the presence of evergreen forest, we conducted sap flow measurements to analyze the transpiration process that maintains water uptake through root systems that reach to depths exceeding 8 m. Characteristics of the evaporation from the forest floor that form an important element of the evaporation system were estimated in both evergreen and deciduous forests.

BRAZILIAN FOREST SEEDS: A PRECARIOUS BEGINNING, A HEADY PRESENT AND THE FUTURE, WILL IT BE PROMISING?

Directory of Open Access Journals (Sweden)

João Paulo Ribeiro-Oliveira

2014-09-01

Full Text Available http://dx.doi.org/10.5902/1980509815738By analyzing the trajectory of forest seed sector, it is widely known the relationship between the studies on native species and the Brazilian Forest Legislation. The Brazilian market for forest seed species is mostly informal and there are only a few species with laboratory tests registered in the Rules for Seed Testing (RAS. However, Law number 10,711, when ruling as to the marketing of seeds and seedlings, granted legal subsidies to promote the formalization of the forest seeds industry. Compliance with this law is conditioned to standardized laboratory methodologies for evaluating seed quality. For this reason, the formulation of a supplement or specific RAS for native forest seeds seems to be near. This fact will certainly consolidate the national seed industry sector. However, what were the paths that native forest seed science had to walk down to reach this standardization? What are the prospects for the future relating to the native forest seed sector? These are just some of the questions this work intends to answer, based on the perspectives of forestry and environmental organizations, such as the Seeds Networks.

Perceptions on the Importance of Forest Sector Innovations: Biofuels, Biomaterials, or Niche Products?

Directory of Open Access Journals (Sweden)

T. Stern

2018-05-01

Full Text Available New innovations are called for to renew the European forest sector into bioeconomy. However, little research exists on how the industry innovativeness is publicly perceived. Using data collected with an online questionnaire in four European countries, we investigate perceptions related to forest sector innovations on 13 current and new bioeconomy-related products and services. Altogether, 218 valid responses were received in 2015, and the data were analysed using descriptive statistics, performance-importance analysis, and Gartner’s innovation hype cycle. Based on our results, the respondents were in the strongest agreement that the forest sector has since the year 2000 has produced innovations related to wood building systems, construction materials, and wood composites. In the next 15 years, they foresaw a decline in innovations related to biofuels and paper products. The European forest sector also has future potential in wood construction, which is likely related to international policy targets related to carbon mitigation and capture. The observed variation in perceptions among the respondents on forest sector innovativeness calls for strengthening industry R&D, as well as by improving societal awareness of ongoing innovation projects by developing better communication.

Uncertainty in future water supplies from forests: hydrologic effects of a changing forest landscape

Jones, J. A.; Achterman, G. L.; Alexander, L. E.; Brooks, K. N.; Creed, I. F.; Ffolliott, P. F.; MacDonald, L.; Wemple, B. C.

Forests account for 33 percent of the U.S. land area, process nearly two-thirds of the fresh water supply, and provide water to 40 percent of all municipalities or about 180 million people. Water supply management is becoming more difficult given the increasing demand for water, climate change, increasing development, changing forest ownership, and increasingly fragmented laws governing forest and watershed management. In 2006, the US National Research Council convened a study on the present understanding of forest hydrology, the hydrologic effects of a changing forest landscape, and research and management needs for sustaining water resources from forested landscapes. The committee concluded that while it is possible to generate short-term water yield increases by timber harvesting, there are a variety of reasons why active forest management has only limited potential to sustainably increase water supplies. These include the short-term nature of the increases in most environments, the timing of the increases, the need for downstream storage, and that continuing ground- based timber harvest can reduce water quality. At the same time, past and continuing changes in forest structure and management may be altering water supplies at the larger time and space scales that are of most interest to forest and water managers. These changes include the legacy of past forest management practices, particularly fire suppression and clearcutting; exurban sprawl, which permanently converts forest land to nonforest uses; effects of climate change on wildfires, insect outbreaks, forest structure, forest species composition, snowpack depth and snowmelt; road networks; and changes in forest land ownership. All of these changes have the potential to alter water quantity and quality from forests. Hence, the baseline conditions that have been used to estimate sustained water yields from forested watersheds may no longer be applicable. Stationarity also can no longer be assumed for the

A new look at the forest industry and global warming

International Nuclear Information System (INIS)

Atkinson, W.

2000-01-01

The relationship between cutting and replanting a climax forest and the control of carbon dioxide emission is examined. The result is a new interpretation which suggests that cutting and replanting of mature trees may actually benefit the environment, provided that the wood goes to long-lasting uses such as houses or furniture. The new interpretation rests on the concept of carbon sequestration technology, or sucking carbon away from the air where it cannot turn up the heat. It is suggested that when an old-growth forest is harvested, its 'carbon tank' is emptied. Second-growth stands that arise to replace the old-growth will bind carbon for several hundred years, until carbon equilibrium is re-established. If the wood produced from harvesting the old-growth forest goes to short-term uses such as for example toilet paper, the carbon locked up in the wood will return to the atmosphere within a matter of a few weeks, with the result that there is no net removal of carbon dioxide. However, if the harvested wood is used to produce houses or furniture (i.e. long-term uses, estimated at 65-70 years) the wood will continue to function as a carbon sink, the carbon will remain locked away from the air, while the replacement saplings trap and bind new carbon. Even after the 65-70 years life expectancy as a house or furniture the wood, at the expected decay rate of three per cent or less per year in an anaerobic landfill, the wood will not release all its stored carbon for a century or more, hence the result is a net removal of atmospheric carbon dioxide. Alternatively, wood from a demolished house could be used as feedstock for generating engine fuels such as methanol. The release of carbon dioxide to the atmosphere would be no greater than allowing the wood to decay naturally. Converted to methanol, it would displace its BTU equivalent in fossil fuels

Generally, although all industrial by product can be toxic and non-toxic pollutant that have potential hazard for human being and environmental. One of these pollutants is carbon dioxide that has potential contribution for greenhouse effect. Although carbon dioxide can be absorbed by plants at the forest but quantity of this emission more higher than quantity of forest area. For this reason rehabilitation of the forest and diversifications and energy saving can be used for decreasing of greenhouse effect. The synergy action such as economical instrumentation (specially microeconomics) can be implemented base on regulators, taxing and incentive and effluent charge by deeper assessment on environmental economics. By identification of quality and quantity fossil fuels that was burned in the industrial process so with stoichiometry calculation will be found quantity of carbon dioxide emission and the taxes can be estimated.

Ontario electricity rates and industrial competitiveness

International Nuclear Information System (INIS)

2006-01-01

Industrial electricity prices in Ontario rose significantly after the opening of the competitive Ontario electricity market in 2002, thereby widening the gap between industrial electricity prices in Ontario and those in other Canadian provinces. Navigant Consulting Ltd. conducted this study at the request of the Association of Major Power Consumers in Ontario (AMPCO) to research and compare current and historical electricity prices in Ontario and other jurisdictions in North America. The study provided an independent analysis of how industrial electricity prices in Ontario compare to those in other jurisdiction in which AMPCO members operate. It also formed the basis for comparing the impacts of electricity policy on the economic competitiveness of major power consumers in Ontario. The relative electricity intensity in the United States, Ontario and other Canadian provinces was reviewed for specific industries, including forest products, steel manufacturing, petroleum refining, chemical manufacturing and cement manufacturing. Publicly available aggregate data from Statistics Canada and the United States Bureau of the Census was then used to compare average electricity prices for industrial customers in Ontario. The data confirmed that Ontario has experienced a decline in its competitive price advantage in industrial electricity. Delivered industrial electricity prices in Ontario have increased by more than 60 per cent since 2001. Industrial electricity prices in Ontario rose above those in Quebec, Manitoba, British Columbia and New Brunswick. In addition, industrial electricity prices in Ontario rose above those in competing states such as Ohio and Illinois, in part due to the increase in the value of the Canadian dollar. It was concluded that the price increase may lead to a greater decline in economic output in Ontario compared to competing jurisdictions. 2 tabs., 14 figs., 1 appendix

Forest management in India. Local versus state control of forest resources

1998-12-31

Degradation and substantial losses to India`s forests have prompted a change in existing forestry management strategy. The new approach includes recognition of local participation in forestry management schemes but state control over most decisions is still dominant. Seen in terms of a common property resource system, India`s forests lack many of the factors usually considered inherent to successful management programs. Though India`s latest Forest Act affords more local involvement in forestry management, there continues to be an apparent lack of rights for local management groups over decision-making and the resource itself. Can this system enable the required balance between state and local management of India`s forests? 24 refs, 1 tab

Rehabilitation of radioactive contaminated forests

International Nuclear Information System (INIS)

Panfilov, A.V.; Uspenskaya, E.Ju.

2002-01-01

As a result of radiation accidents and nuclear-weapon tests at the territory of the former USSR a part of the Forest Fund of 23 subjects of the Russian Federation has been contaminated by radionuclides. The contaminated forests, which are included in a structure of more than 130 forest management units (leskhozes) and more then 330 local forest management units, as a rule, are located in highly inhabited regions with traditionally intensive forestry management and high level of forest resources use. To provide radiologically safe forest management in the contaminated areas, the Federal Forest Service has developed and validated a special system of countermeasures. Use of this system makes it possible to diminish significantly the dose to personnel, to exclude the use of forest products with contamination exceeding radiological standards and to provide protection of the forest as a biogeochemical barrier to radionuclide migration from contaminated areas to human habitat.

Forests play a key role in the European economy and environment. This role incorporates ecological functions which can be affected by the occurrence of insect infestations, forest fire, heavy snowfall or windfall events. Local or Regional Authorities (LRAs) thus require detailed information on the degradation status of their forests to be able to take appropriate measures for their forest management plans. In the EUFODOS project, state-of-the-art satellite and laser scanning technologies are used to provide forest authorities with cost-effective and comprehensive information on forest structure and damage. One of the six test sites is located in the Austrian province of Styria where regional forest authorities have expressed a strong need for detailed forest parameters in protective forest. As airborne laser-scanning data is available, it will be utilized to derive detailed forest parameters such as the upper forest border line, tree height, growth classes, forest density, vertical structure or volume. At the current project status, the results of (i) the forest border line, (ii) the segmentation of forest stands and (iii) the tree top detection are available and presented including accuracy assessment and interim results are shown for timber volume estimations. The final results show that the forest border can be mapped operationally with an overall accuracy of almost 99% from LiDAR data. For the segmentation of forest stands, a comparison of the automatically derived result with visual-manual delineation showed in general a more detailed segmentation result, but for all visual-manual segments a congruence of 87% within a 4 m buffer. Tree top detections were compared to stem numbers estimated based on angle-count samplings in a field campaign, which led to a correlation coefficient (R) of 0.79.

The Forest Energy Project of Central Finland (1994 - 1996) was one of the leading regional demonstration projects in Finland for testing and studying of the complete energy wood delivery chains and energy wood utilisation. The target of this provincial project was to collect and demonstrate the most promising energy wood procurement technologies and methods for utilisation of energy producers, forest industry and small and medium sized industries co- operating with forest owners, contractors and forest organisations. The project was a large development and technology transfer venture concentrated primarily on practical needs. Total delivery chains were formed of the best machine and method alternatives, and they were also demonstrated. The project offered hence a wide test field for regional and national techno / economical wood fuel development. The Forest Energy Project of Central Finland was a demonstration project supervised by the Regional Council of Central Finland. The project was a part of the national Bioenergy Research Programme. VTT Energy and the Forestry Board of Central Finland were responsible for the practical development work. A large number of provincial partners interested in wood fuels took part in the project. The project were carried out during the years 1994 - 1996. The total costs were 4.4 million FIM. The aim is to create a practical model for the entire system, by which enables the economically profitable increment of the utilisation of chip fuels in Central Finland by 100 GWh/1996 and 500 GWh/a (about 250 000 m{sup 3}) to the end of the decade.

Drought effects on large fire activity in Canadian and Alaskan forests

International Nuclear Information System (INIS)

Xiao Jingfeng; Zhuang Qianlai

2007-01-01

Fire is the dominant disturbance in forest ecosystems across Canada and Alaska, and has important implications for forest ecosystems, terrestrial carbon dioxide emissions and the forestry industry. Large fire activity had increased in Canadian and Alaskan forests during the last four decades of the 20th century. Here we combined the Palmer Drought Severity Index and historical large fire databases to demonstrate that Canada and Alaska forest regions experienced summer drying over this time period, and drought during the fire season significantly affected forest fire activity in these regions. Climatic warming, positive geopotential height anomalies and ocean circulation patterns were spatially and temporally convolved in causing drought conditions, which in turn enhanced fuel flammability and thereby indirectly affected fire activity. Future fire regimes will likely depend on drought patterns under global climate change scenarios

permafrost areas. Overall, Russia should expect a disproportionate escalation of fire regimes compared to increasing climatic fire danger. Thus, development and implementation of an efficient adaptation strategy is a pressing problem of current forest management of the country. An appropriate system of forest fire protection which would be able to meet challenges of future climates is a corner stone of such a strategy. We consider possible systems solutions of this complex problem including (1) integrated ecological and socio-economic analysis of current and future fire regimes; (2) regional requirements to and specific features of a new paradigm of forest fire protection in the boreal zone of Northern Eurasia; (3) anticipatory strategy of the prevention of large-scale disturbances in forests, including adaptation of forest landscapes to the future climates (regulation of tree composition; setup of relevant spatial structure of forest landscapes; etc.); (4) implementation of an effective system of forest monitoring as part of integrated observing systems; (5) transition to ecologically-friendly systems of industrial development of northern territories; (6) development of new/ improvement of existing legislation and institutional frameworks of forest management which would be satisfactory to react on challenges of climate change; and (6) international cooperation.

The carbon balance and greenhouse effects of the Finnish forest sector at present, in the past and future

Energy Technology Data Exchange (ETDEWEB)

Pingoud, K [Technical Research Centre of Finland, Espoo (Finland)

1997-12-31

In this study the greenhouse impact of the total Finnish forest sector was considered, which means that the estimated emissions and sink effects from exported forest products were also included. The forest biomass is and seems to be in the next decades the most important factor in the carbon balance of the total forest sector. The development alternatives of forest industries and waste management practices has still a remarkable influence on the greenhouse impact of the Finnish forest sector. The waste management practices in the future has an important influence on the emissions but the exact net greenhouse impact of the landfills is still uncertain. However, the methane emissions from existing landfills can be reduced essentially by gas recovery. Increased incineration and energy recovery of wood waste (and replacing fossil fuel use by it) is also a future alternative for reducing the greenhouse effects in the forest sector. The sequestration of carbon by increasing the storages of long-lived wood products in use meets difficulties in practice because of all the material losses in wood using chain and the natural removal of old wood products. An important advantage of mechanical wood processing and the succeeding refinement chain is still their relative low use of energy

Local versus landscape-scale effects of anthropogenic land-use on forest species richness

Science.gov (United States)

Buffa, G.; Del Vecchio, S.; Fantinato, E.; Milano, V.

2018-01-01

The study investigated the effects of human-induced landscape patterns on species richness in forests. For 80 plots of fixed size, we measured human disturbance (categorized as urban/industrial and agricultural land areas), at 'local' and 'landscape' scale (500 m and 2500 m radius from each plot, respectively), the distance from the forest edge, and the size and shape of the woody patch. By using GLM, we analyzed the effects of disturbance and patch-based measures on both total species richness and the richness of a group of specialist species (i.e. the 'ancient forest species'), representing more specific forest features. Patterns of local species richness were sensitive to the structure and composition of the surrounding landscape. Among the landscape components taken into account, urban/industrial land areas turned out as the most threatening factor for both total species richness and the richness of the ancient forest species. However, the best models evidenced a different intensity of the response to the same disturbance category as well as a different pool of significant variables for the two groups of species. The use of groups of species, such as the ancient forest species pool, that are functionally related and have similar ecological requirements, may represent an effective solution for monitoring forest dynamics under the effects of external factors. The approach of relating local assessment of species richness, and in particular of the ancient forest species pool, to land-use patterns may play an important role for the science-policy interface by supporting and strengthening conservation and regional planning decision making.

Pyrogenic Transformations of the Baikal Lake Forests. Retrospective and Contemporary Issues

Directory of Open Access Journals (Sweden)

M. D. Yevdokimenko

2014-06-01

Full Text Available In the forests of the Baikal Lake basin annual fire activity historically has been higher as compared to surrounding forest areas due to specific climatic conditions and altitude-controlled vegetation structure. The regional forests, predominantly light coniferous, develop under a high or, in dry years, extreme-fire-activity regime. Common pine and larch tree stands of fire origin are periodically thinned by fire. The productivity of the fire-intact parts of such stands decreases as a result of fire-caused soil condition disturbances. In extreme fire years, large fires cover landscapes and lead to irreversible forest ecosystem degradation and, hence, to local deforestation. In the past, forest fire activity and area burned increased with increasing use of the regional forests beginning with hunting, wood extraction by dwellers of local settlements, Trans-Siberian Rail Road building and, finally, industrial-scale logging. In 1970–1980, the regional fire situation was successfully controlled due to improvements of forest use and protection. However, the recently relaxed forest economy standards have resulted in loss of the progress achieved.

Opportunities and impediments to the expansion of forest bioenergy in Australia

International Nuclear Information System (INIS)

Raison, R.J.

2006-01-01

There are significant opportunities for expansion of a forest bioenergy industry in Australia based on distributed electricity generation and production of liquid fuels (ethanol and bio-oil). If the large amounts of forest residues already available annually could be utilized, this would deliver useful greenhouse benefits, assist regeneration of new forests that have increased environmental values, and benefit silvicultural management. Creation of new forests in low rainfall environments for both environmental and commercial reasons will also provide residues in the future that could be used for energy production, thus enhancing overall viability of such ventures. Currently, there are several serious impediments to realising the potential. These include: - Large reserves of accessible coal, and low cost of electricity generated in coal-fired power plants. - Uncertain greenhouse and renewable energy policy (specifically that relating to implementation of the Mandated Renewable Energy Target (MRET)). - Lack of proven efficient small-scale technology to enable distributed electricity generation that would reduce transportation costs for delivery of biofuels. - Controversy over the sustainable use of native forest residues for renewable energy generation. - Lack of markets for environmental credits (carbon, salinity, biodiversity). - Lack of efficient processes for producing ethanol from wood, inadequate commercial products from lignin, and the need for further development before diesel engines can be run on bio-oil for stationary power generation and transport. In Australia, apart from the use of firewood for domestic heating, forest bioenergy has developed only to a very limited extent, despite the existence of significant opportunities. A major impediment to expansion is lack of public acceptance and support, especially for the use of native forest residues which are the main available biomass source. A concerted effort at several levels is needed to address this

Impacts of elevated atmospheric CO2 on forest trees and forest ecosystems: knowledge gaps

International Nuclear Information System (INIS)

Karnosky, D.F.

2003-06-01

Atmospheric CO 2 is rising rapidly, and options for slowing the CO 2 rise are politically charged as they largely require reductions in industrial CO 2 emissions for most developed countries. As forests cover some 43% of the Earth's surface, account for some 70% of terrestrial net primary production (NPP), and are being bartered for carbon mitigation, it is critically important that we continue to reduce the uncertainties about the impacts of elevated atmospheric CO 2 on forest tree growth, productivity, and forest ecosystem function. In this paper, 1 review knowledge gaps and research needs on the effects of elevated atmospheric CO 2 on forest above- and below-ground growth and productivity, carbon sequestration, nutrient cycling, water relations, wood quality, phonology, community dynamics and biodiversity, antioxidants and stress tolerance, interactions with air pollutants, heterotrophic interactions, and ecosystem functioning. Finally, 1 discuss research needs regarding modelling of the impacts of elevated atmospheric CO 2 on forests. Even though there has been a tremendous amount of research done with elevated CO 2 and forest trees, it remains difficult to predict future forest growth and productivity under elevated atmospheric CO 2 . Likewise, it is not easy to predict how forest ecosystem processes will respond to enriched CO 2 . The more we study the impacts of increasing CO 2 , the more we realize that tree and forest responses are yet largely uncertain due to differences in responsiveness by species, genotype, and functional group, and the complex interactions of elevated atmospheric CO 2 with soil fertility, drought, pests, and co-occurring atmospheric pollutants such as nitrogen deposition and O 3 . Furthermore, it is impossible to predict ecosystem-level responses based on short-term studies of young trees grown without interacting stresses and in small spaces without the element of competition.

The evolution of international policies and mechanisms to advance sustainable forest management and mitigate global climate change

International Nuclear Information System (INIS)

Bologna, J.; Lyke, J.; Theophile, K.

1995-01-01

Scientific findings regarding global climate change and deforestation led industrialized nations to bring both issues to the forefront of an international dialogue on the environment. International institutional attention to deforestation began in 1985 with the Tropical Forestry Action Program which helped countries develop plans for sustainable forest management. A few years later, the International Tropical Timber Organization, though designed to facilitate tropical timber trade, adopted guidelines for sustainable management of tropical production forests. Next, the activities before and after UNCED established a general set of forest principles and regional efforts to define sustainable forest management. The World Bank has also sought to reduce past lending failures that led to deforestation and other environmental degradation, through programmatic redirections and macro-economic policy reforms. Finally, through innovative financial incentives, industrialized and developing countries are identifying opportunities to offset debts and increase economic development without depleting forest resources. Collectively, these efforts have let to some trends that support sustainable forest management and mitigate climate change. The upcoming years will see a proactive set of multilateral programs to address deforestation, an increasing link between trade and the environment, and more uses of financial incentives to encourage sustainable forest management

Forests and competing land uses in Kenya

Science.gov (United States)

Allaway, James; Cox, Pamela M. J.

1989-03-01

Indigenous forests in Kenya, as in other developing countries, are under heavy pressure from competing agricultural land uses and from unsustainable cutting. The problem in Kenya is compounded by high population growth rates and an agriculturally based economy, which, even with efforts to control birth rates and industrialize, will persist into the next century. Both ecological and economic consequences of these pressures need to be considered in land-use decision making for land and forest management to be effective. This paper presents one way to combine ecological and economic considerations. The status of principal forest areas in Kenya is summarized and competing land uses compared on the basis of ecological functions and economic analysis. Replacement uses do not match the ecological functions of forest, although established stands of tree crops (forest plantations, fuel wood, tea) can have roughly comparable effects on soil and water resources. Indigenous forests have high, although difficult to estimate, economic benefits from tourism and protection of downstream agricultural productivity. Economic returns from competing land uses range widely, with tea having the highest and fuel wood plantations having returns comparable to some annual crops and dairying. Consideration of ecological and economic factors together suggests some trade-offs for improving land allocation decisions and several management opportunities for increasing benefits or reducing costs from particular land uses. The evaluation also suggests a general strategy for forest land management in Kenya.

The use of forest chips in Finland

International Nuclear Information System (INIS)

Hakkila, P.

2001-01-01

International commitments require the industrial world to restrict their greenhouse gas emissions. In Finland, where the annual timber cut per capita is more than ten times the average cut in the other EU countries, the primary means to reduce CO 2 emissions is to replace fossil fuels with forest biomass. The annual consumption of wood-based energy corresponds to 6 million tonnes of oil equivalent (toe) or almost 20% of the total primary energy consumption. The goal is to rise the annual production of wood-based energy to 7.8 million toe by 2010. Substantial part of the targeted increase could be obtained by forest chips produced of unmerchantable small-diameter trees and logging residues. The goal for 2010 is to use 5 million solid m 3 of forest chips, which equals to 0.9 million toe. The use of forest chips is increasing. About 474 000 solid m 3 of forest chips were used as fuel in 1999. At the moment, the growth is rapid especially in cogeneration plants producing both heat and electricity. The growth is based primarily on chips obtained from logging residues. The price of forest chips decreased considerably during the 1990s but the price range remained wide. Chips made of logging residues are cheaper than those made of small trees. The average price of forest chips at the plant, VAT excluded, is about 53 FIM per MWh. In Sweden, the average price is more than 40% higher

McLellan, Iain; Hursthouse, Andrew; Morrison, Calum; Varela, Adélia; Pereira, Cristina Silva

2014-02-01

A major concern for the cork and wine industry is 'cork taint' which is associated with chloroanisoles, the microbial degradation metabolites of chlorophenols. The use of chlorophenolic compounds as pesticides within cork forests was prohibited in 1993 in the European Union (EU) following the introduction of industry guidance. However, cork produced outside the EU is still thought to be affected and simple, robust methods for chlorophenol analysis are required for wider environmental assessment by industry and local environmental regulators. Soil samples were collected from three common-use forests in Tunisia and from one privately owned forest in Sardinia, providing examples of varied management practice and degree of human intervention. These provided challenge samples for the optimisation of a HPLC-UV detection method. It produced recoveries consistently >75% against a soil CRM (ERM-CC008) for pentachlorophenol. The optimised method, with ultraviolet (diode array) detection is able to separate and quantify 16 different chlorophenols at field concentrations greater than the limits of detection ranging from 6.5 to 191.3 μg/kg (dry weight). Application to a range of field samples demonstrated the absence of widespread contamination in forest soils at sites sampled in Sardinia and Tunisia.

Area of study: Spain and California (USA. Material and methods: This conceptual article has developed a critical revision of the existing literature on the main economic issues for multifunctional natural forest silviculture in the last decades. Main results: Multifunctional natural silviculture has secular roots as a local practice, but as a science of the natural environment applied to the economic management of forest lands it is still in the process of maturation. Timber silviculture remains the central concern of forest economics investment in scientific publications. By contrast, silvicultural modeling of the natural growth of firewood, browse and other non-timber forest products from trees and shrubs receives scant attention in scientific journals. Even rarer are publications on multifunctional natural silviculture for forest and woodland managements, including environmental services geared to people’s active and passive consumption. Under this umbrella, private environmental self-consumption is represented by the amenities enjoyed by private non-industrial landowners. As for environmental public products, the most relevant are carbon, water, mushrooms, recreation, landscape and threatened biodiversity. Research highlights: This paper is a good example for the conceptual research on forestry techniques and economic concepts applied to multifunctional silviculture in Mediterranean areas of Spain and California. The combination of technical knowledge and private and public economic behaviors definitively contributes to the multifunctional management of natural forest systems.

2013-05-01

Full Text Available Forests play a key role in the European economy and environment. This role incorporates ecological functions which can be affected by the occurrence of insect infestations, forest fire, heavy snowfall or windfall events. Local or Regional Authorities (LRAs thus require detailed information on the degradation status of their forests to be able to take appropriate measures for their forest management plans. In the EUFODOS project, state-of-the-art satellite and laser scanning technologies are used to provide forest authorities with cost-effective and comprehensive information on forest structure and damage. One of the six test sites is located in the Austrian province of Styria where regional forest authorities have expressed a strong need for detailed forest parameters in protective forest. As airborne laser-scanning data is available, it will be utilized to derive detailed forest parameters such as the upper forest border line, tree height, growth classes, forest density, vertical structure or volume. At the current project status, the results of (i the forest border line, (ii the segmentation of forest stands and (iii the tree top detection are available and presented including accuracy assessment and interim results are shown for timber volume estimations. The final results show that the forest border can be mapped operationally with an overall accuracy of almost 99% from LiDAR data. For the segmentation of forest stands, a comparison of the automatically derived result with visual-manual delineation showed in general a more detailed segmentation result, but for all visual-manual segments a congruence of 87% within a 4 m buffer. Tree top detections were compared to stem numbers estimated based on angle-count samplings in a field campaign, which led to a correlation coefficient (R of 0.79.

Development of a spatial forest data base for the eastern boreal forest region of Ontario. Forest fragmentation and biodiversity project technical report No. 14

NONE

1994-12-31

In 1991, a spatial forest database over large regions of Ontario was initiated as the basis for research into forest fragmentation and biodiversity using data generated from the digital analysis of LANDSAT thematic mapper satellite data integrated into a geographic information system (GIS). The project was later extended into the eastern segment of the Boreal forest system. This report describes preparation of the spatial forest data base over the eastern Boreal Forest Region that extends from the northern boundary of the Great Lakes-St. Lawrence Forest Region and the southern margin of the James Bay Lowland, between the Ontario-Quebec border and a point west of Michipicoten on Lake Superior. The report describes the methodology used to produce the data base and results, including mapping of water, dense and sparse conifer forest, mixed forest, dense and sparse deciduous forest, poorly vegetated areas, recent cutovers of less than 10 years, old cutovers and burns, recent burns of less than 10 years, wetlands, bedrock outcrops, agriculture, built-up areas, and mine tailings.

Geospatial technology perspectives for mining vis-a-vis sustainable forest ecosystems

Directory of Open Access Journals (Sweden)

Goparaju Laxmi

2017-06-01

Full Text Available Forests, the backbone of biogeochemical cycles and life supporting systems, are under severe pressure due to varied anthropogenic activities. Mining activities are one among the major reasons for forest destruction questioning the survivability and sustainability of flora and fauna existing in that area. Thus, monitoring and managing the impact of mining activities on natural resources at regular intervals is necessary to check the status of their depleted conditions, and to take up restoration and conservative measurements. Geospatial technology provides means to identify the impact of different mining operations on forest ecosystems and helps in proposing initiatives for safeguarding the forest environment. In this context, the present study highlights the problems related to mining in forest ecosystems and elucidates how geospatial technology can be employed at various stages of mining activities to achieve a sustainable forest ecosystem. The study collates information from various sources and highlights the role of geospatial technology in mining industries and reclamation process.

The U.S. Forest Service (USFS) Special Uses-Lands Program is in jeopardy. Although this program, authorized in Title 36, Part 251, of the U.S. Code of Federal Regulations (36 CFR Part 251), ranks among the top four revenue-generating programs for use of National Forest System (NFS) lands, along with the Timber, Minerals, and Special Uses-Recreation Programs, the Special Uses-Lands Program is in a state of neglect. Repeated cuts in funding (a decrease of 26% from fiscal years 2010 to 2014) are adversely affecting staffing and training, which in turn is affecting timely permit processing and ultimately the public’s ability to use and benefit from NFS lands. In addition, highly experienced staff with valuable institutional knowledge of the program have begun to retire. The ability of the program to function under these dire circumstances can be attributed to the dedication of Special Uses staff to the program and their commitment to the public. The initial focus of this report was to identify opportunities for improving performance of permitting and review for large energy infrastructure-related projects. However, it became clear during this analysis that these projects are generally adequately staffed and managed. This is due in large part to the availability of cost-recovery dollars and the high-profile nature of these projects. However, it also became apparent that larger issues affecting the bulk of the work of the Special Uses-Lands Program need to be addressed immediately. This report is a preliminary examination of the state of the Special Uses-Lands Program and focuses on a few key items requiring immediate attention. Further investigation through case studies is recommended to dig deeper into the Special Uses-Lands Program business process to determine the most costeffective strategies for streamlining the overall process and the metrics by which performance can be evaluated, including for the permitting and tracking of energy infrastructure projects.

The Forest of Romania: a Social - Economic's Dramma

Directory of Open Access Journals (Sweden)

Toma Roman

2009-06-01

Full Text Available Forests were covering at the start of the third millennium around 26.5% of Romania's territory. Comprised into forest zones expanded in all historical provinces of the country, they are representing an important economic resource, an also an essential factor of the man-environment equilibrium. The organization of the rational exploitation of the forestry fund, adopted ever since the XIX Century, was abandoned after the forests nationalization, imposed by the communist regime in 1948. Urbanization and industrialization, held in view by this regime, did not take into account the ecological requirements and neither those linked to the renewal of the natural economic resources. The transition coming after the fall of communism, with pervert economic, psychological and sociological effects, has led to a savage exploitation of the forestry fund, the lack of some compensation measures (re-forestations, young forest protection, under the context of statal authority's dissolution (after the excessive communist authoritarism, having catastrophic consequences: land slides, desertification, pollution. The remake of the forest ownership structure, from before nationalization, is not, as a consequence, sufficient, the putting into possession having to be accompanied, in the goal of remaking the natural harmony of man with his existential environment, by a series of economic, legislative, educational initiatives, which the EU integration could facilitate.

Restoring Forests and Associated Ecosystem Services on Appalachian Coal Surface Mines

Zipper, Carl E.; Burger, James A.; Skousen, Jeffrey G.; Angel, Patrick N.; Barton, Christopher D.; Davis, Victor; Franklin, Jennifer A.

2011-05-01

Surface coal mining in Appalachia has caused extensive replacement of forest with non-forested land cover, much of which is unmanaged and unproductive. Although forested ecosystems are valued by society for both marketable products and ecosystem services, forests have not been restored on most Appalachian mined lands because traditional reclamation practices, encouraged by regulatory policies, created conditions poorly suited for reforestation. Reclamation scientists have studied productive forests growing on older mine sites, established forest vegetation experimentally on recent mines, and identified mine reclamation practices that encourage forest vegetation re-establishment. Based on these findings, they developed a Forestry Reclamation Approach (FRA) that can be employed by coal mining firms to restore forest vegetation. Scientists and mine regulators, working collaboratively, have communicated the FRA to the coal industry and to regulatory enforcement personnel. Today, the FRA is used routinely by many coal mining firms, and thousands of mined hectares have been reclaimed to restore productive mine soils and planted with native forest trees. Reclamation of coal mines using the FRA is expected to restore these lands' capabilities to provide forest-based ecosystem services, such as wood production, atmospheric carbon sequestration, wildlife habitat, watershed protection, and water quality protection to a greater extent than conventional reclamation practices.

Composition and Elevation of Spruce Forests Affect Susceptibility to Bark Beetle Attacks: Implications for Forest Management

Directory of Open Access Journals (Sweden)

Massimo Faccoli

2014-01-01

Full Text Available The spruce bark beetle, Ips typographus (L. (Coleoptera: Curculionidae, Scolytinae, is one of the most destructive insects infesting spruce forests in Europe. Data concerning infestations of I. typographus occurring over the last 19 years (1994–2012 on the Southern Alps were analyzed in seven spruce forest types: (1 pure spruce plantations; (2 pure spruce reforestations; (3 pure spruce mountain forests; (4 pure spruce alpine forests; (5 spruce-conifer mixed forests; (6 spruce-broadleaf mixed forests; and (7 spruce-conifer-broadleaf mixed forests. The collected data included the amount of I. typographus damage and the location and composition of the infested forests. The results indicate that different forest types are differently susceptible to I. typographus. Plantations, reforestations and mountain spruce forests show mean damage and mean number of infestations higher than other forest types. Within pure spruce forests, alpine forests growing at high elevations (>1300 m suffer low damage. Furthermore, the mean number of infestation spots recorded annually in the different spruce forest types is negatively correlated with a Naturality Index value. The results suggest that forest composition and elevation are the main factors driving the risk of I. typographus damage. A new management strategy for some spruce forest types is needed, with a progressive reduction of pure spruce forests at low altitude and an increase of broadleaf composition.

Economics of forest and forest carbon projects. Translating lessons learned into national REDD+ implementation

Energy Technology Data Exchange (ETDEWEB)

Zaballa Romero, M.; Traerup, S.; Wieben, E.; Ravnkilde Moeller, L.; Koch, A.

2013-01-15

The financial implications of implementing a new forest management paradigm have not been well understood and have often been underestimated. Resource needs for e.g., stakeholder consultation, capacity building and addressing the political economy are seldom fully accounted for in the resource needs estimates put forward in connection to REDD+. This report investigates the economics of implementing forest and REDD+ projects through eight case studies from Africa, Latin America and Asia, analyzing real forest and REDD+ investments. The report is part of efforts to share financial experiences and lessons learned with policymakers, project developers and stakeholders, with the objective to inform forest project and strategy development. It presents experiences and advice on the risks, costs and revenues of forest projects, thereby informing not only the development of future REDD+ initiatives but also the testing of advanced market commitments as a finance option for sustainable forest management. The findings in the report underline the fact that only through sound and transparent financial information will forest projects and national forest initiatives become interesting for private financial institutions and comparable with other investment opportunities. It is therefore important to include robust analysis of the operations business case and its financial attractiveness to commercial investors, early in the design process. As for the economics of forest and forest carbon projects, it appears that REDD+ payments alone, especially at current prices, will not deliver the revenues that cover all expenses of transparent and long-term mitigation of forest carbon emissions. Instead the findings underline the importance of building up forest operations which effectively manages risk and delivers several revenue streams. These findings are aligned with the advocacy efforts of UNEP and the UN-REDD Programme on multiple benefits and the combination of various funding and

Estimating Aboveground Forest Carbon Stock of Major Tropical Forest Land Uses Using Airborne Lidar and Field Measurement Data in Central Sumatra

Tropical forests are providing environmental goods and services including carbon sequestration, energy regulation, water fluxes, wildlife habitats, fuel, and building materials. Despite the policy attention, the tropical forest reserve in Southeast Asian region is releasing vast amount of carbon to the atmosphere due to deforestation. Establishing quality forest statistics and documenting aboveground forest carbon stocks (AFCS) are emerging in the region. Airborne and satellite based large area monitoring methods are developed to compliment conventional plot based field measurement methods as they are costly, time consuming, and difficult to implement for large regions. But these methods still require adequate ground measurements for calibrating accurate AFCS model. Furthermore, tropical region comprised of varieties of natural and plantation forests capping higher variability of forest structures and biomass volumes. To address this issue and the needs for ground data, we propose the systematic collection of ground data integrated with airborne light detection and ranging (LiDAR) data. Airborne LiDAR enables accurate measures of vertical forest structure, including canopy height and volume demanding less ground measurement plots. Using an appropriate forest type based LiDAR sampling framework, structural properties of forest can be quantified and treated similar to ground measurement plots, producing locally relevant information to use independently with satellite data sources including synthetic aperture radar (SAR). In this study, we examined LiDAR derived forest parameters with field measured data and developed general and specific AFCS models for tropical forests in central Sumatra. The general model is fitted for all types of natural and plantation forests while the specific model is fitted to the specific forest type. The study region consists of natural forests including peat swamp and dry moist forests, regrowth, and mangrove and plantation forests

Trends and Possible Future Developments in Global Forest-Product Markets—Implications for the Swedish Forest Sector

Directory of Open Access Journals (Sweden)

Ragnar Jonsson

2011-01-01

Full Text Available This paper analyzes trends and possible future developments in global wood-product markets and discusses implications for the Swedish forest sector. Four possible futures, or scenarios, are considered, based on qualitative scenario analysis. The scenarios are distinguished principally by divergent futures with respect to two highly influential factors driving change in global wood-product markets, whose future development is unpredictable. These so-called critical uncertainties were found to be degrees to which: (i current patterns of globalization will continue, or be replaced by regionalism, and (ii concern about the environment, particularly climate change, related policy initiatives and customer preferences, will materialize. The overall future of the Swedish solid wood-product industry looks bright, irrespective of which of the four possible futures occurs, provided it accommodates the expected growth in demand for factory-made, energy-efficient construction components. The prospects for the pulp and paper industry in Sweden appear more ambiguous. Globalization is increasingly shifting production and consumption to the Southern hemisphere, adversely affecting employment and forest owners in Sweden. Further, technical progress in information and communication technology (ICT is expected to lead to drastic reductions in demand for newsprint and printing paper. Chemical pulp producers may profit from a growing bio-energy industry, since they could manufacture new, high-value products in integrated bio-refineries. Mechanical pulp producers cannot do this, however, and might suffer from higher prices for raw materials and electricity.

Forest health conditions in North America

Tkacz, Borys; Moody, Ben; Castillo, Jaime Villa; Fenn, Mark E.

2008-01-01

Some of the greatest forest health impacts in North America are caused by invasive forest insects and pathogens (e.g., emerald ash borer and sudden oak death in the US), by severe outbreaks of native pests (e.g., mountain pine beetle in Canada), and fires exacerbated by changing climate. Ozone and N and S pollutants continue to impact the health of forests in several regions of North America. Long-term monitoring of forest health indicators has facilitated the assessment of forest health and sustainability in North America. By linking a nationwide network of forest health plots with the more extensive forest inventory, forest health experts in the US have evaluated current trends for major forest health indicators and developed assessments of future risks. Canada and Mexico currently lack nationwide networks of forest health plots. Development and expansion of these networks is critical to effective assessment of future forest health impacts. - The forests of North America continue to face many biotic and abiotic stressors including fragmentation, fires, native and invasive pests, and air pollution

Predicting hydrological response to forest changes by simple statistical models: the selection of the best indicator of forest changes with a hydrological perspective

Forest plays an important role in hydrological cycle, and forest changes will inevitably affect runoff across multiple spatial scales. The selection of a suitable indicator for forest changes is essential for predicting forest-related hydrological response. This study used the Meijiang River, one of the headwaters of the Poyang Lake as an example to identify the best indicator of forest changes for predicting forest change-induced hydrological responses. Correlation analysis was conducted first to detect the relationships between monthly runoff and its predictive variables including antecedent monthly precipitation and indicators for forest changes (forest coverage, vegetation indices including EVI, NDVI, and NDWI), and by use of the identified predictive variables that were most correlated with monthly runoff, multiple linear regression models were then developed. The model with best performance identified in this study included two independent variables -antecedent monthly precipitation and NDWI. It indicates that NDWI is the best indicator of forest change in hydrological prediction while forest coverage, the most commonly used indicator of forest change is insignificantly related to monthly runoff. This highlights the use of vegetation index such as NDWI to indicate forest changes in hydrological studies. This study will provide us with an efficient way to quantify the hydrological impact of large-scale forest changes in the Meijiang River watershed, which is crucial for downstream water resource management and ecological protection in the Poyang Lake basin.
