    A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere, i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest management can contribute to the sequestration of carbon. The potential role of forests and forestry in sequestrating carbon to reduce the buildup of greenhouse gases in the atmosphere is now well recognized. A number of alternative approaches to utilizing forestry and forest management for carbon sequestration are examined. These include forest protection; the management of forests for carbon for joint products, i.e., the management of forests to generate both carbon and timber as products; the establishment of plantation forests dedicated to carbon sequestration; and increased production of wood products. Replacing other materials with wood will sequester carbon while reducing energy requirements, thereby reducing carbon emissions. Studies examining the costs of carbon sequestration using forestry are also discussed. The recent Kyoto Protocol (K.P.) explicitly recognizes certain forestry activities as “certifiable” for sequestration credits. But some definitions and aspects of carbon sequestration through forestry were left incomplete or inadequately defined by the Protocol. Furthermore, the KP has changed due to the recent withdrawal of the US for the Protocol (although not from the Kyoto Process). Nevertheless, further clarification is necessary to understand the full potential and set of opportunities from forestry both within the framework of the Protocol and more generally. Alternative types of vehicles for sequestration credits are discussed below,m both within and outside the context of the KP , and their advantages and disadvantages in terms of periods covered and liability are also examined. Finally, some ongoing real-world activities utilizing forestry specifically to sequester carbon are discussed.forests, carbon, sinks, sequestration, forest management, Kyoto Protocol

    Impact of forestry practices on fitness correlates and population productivity in an open-nesting bird species

    In the boreal forests of Fennoscandia, over 99% of the forest area has been altered by forestry practices, which has created forests of differing age structures and stand characteristics than primary forest stands. Although many researchers have investigated how forestry affects species abundance, few have assessed how forestry affects fitness correlates of species living in altered habitats, and this has negatively affected management efforts. We experimentally addressed the effect of standard forestry practices on fitness correlates of an open-nesting, long-lived bird species typical to boreal forests of Eurasia, the Siberian Jay (Perisoreus infaustus L.). Using a before-after comparison of reproductive data on the level of territories, we found that standard forestry practices had a strong negative effect on the breeding success of jays. Both partial thinning of territories and partial clearcutting of territories reduced future breeding success by a factor of 0.35. Forestry practices reduced territory occupancy. Thus, over the 15 years of the study the productivity of the affected population declined over 50% as a result of territory abandonment and reduced breeding success. Results of previous studies on Siberian Jays suggest that the strong effect of forest thinning on fitness is explained by the fact that most common predators of nests and adults are visually oriented, and thinning makes prey and nests more visible to predators. The consequences of thinning we observed are likely to apply to a wide range of species that rely on understory to provide visual protection from predators. Thus, our results are important for the development of effective conservation management protocols and for the refinement of thinning practices

    Economic parameters of deforestation

    Recent debate about how timber prices affect deforestation has focused mainly on how log export bans (imposed in many developing countries to protect domestic timber processing) affect deforestation. One side argues that the lower domestic timber prices that result from banning log exports increase deforestation by making forestry less profitable than competing land uses, such as agriculture. The other argues that lower timber prices reduce profits from logging, so they slow down deforestation caused by logging. The author argues that the conflicting views result from simplistic analysis that ignores differences between types of forest. The two positions are reconciled by distinguishing between unmanaged forests (for example, biologically mature, previously unlogged primary forests) and managed forests (such as forest plantations cultivated for periodic harvest). This distinction allows the derivation of unambiguous comparative static results and is useful because many nontimber benefits from forests (such as biodiversity conservation) are associated mainly with unmanaged forests. The distinction between managed and unmanaged forests leads to both unconventional and conventional results. All things being equal, a lower timber price results in larger areas of unmanaged forests and smaller areas of managed forests. That is, measures that reduce the producer price for timber (for example, import restrictions in timber-consuming countries and export restrictions in timber-producing countries) are suitable as a second-best policy to reduce the pressure on unmanaged forest frontiers. Most logging in tropical forests occurs in unmanaged forests, so the claim that trade restrictions (such as log export bans) increase deforestation is inconsistent with profit-maximizing land use. A fee on land used for logging is preferable to a tax on timber output,which is far more common but encourages logging waste. Technological interventions that increase the intensity of forestry or alternative land uses are an ambiguous instrument for the conservation of unmanaged forests. If demand elasticity for outputs is high, an intervention that increases the intensity of agriculture, logging, or other land uses increases incentive for conversion of unmanaged forests. The building of roads is particularly harmful to the conservation of unmanaged forests, as it increases incentives for logging and subsequent alternative land uses. Proper pricing of forest lands would increase land prices and lead to market-driven intensification accompanied by forest protection. Such pricing policies would be preferable to a technological intervention that increases land use intensity with ambiguous outcomes for forest protection. If unmanaged forest is converted to agriculture, the effect of lowering the decisionmaker's discount rate depends on the size of timber rents from logging unmanaged forests. If the standing timber has high commercial value, a lower discount rate would slow conversion of unmanaged forests. If the standing timber has no commercial value, logging is an investment for obtaining future benefits of alternate land use. A lower discount rate would stimulate this investment and increase the conversion of unmanaged forests. Also, if unmanaged forests are converted to managed forests, a lower discount rate can increase conversion since profits from managed forestry are higher with a lower discount rate.Silviculture,Agribusiness,Forestry,Environmental Economics&Policies,Forests and Forestry

    Fuelwood consumption and participation in community forestry in India

    Get PDF
    Decentralized forest management is an important policy issue in India and elsewhere. Yet there are few careful studies of the impacts of community forestry. The authors try to fill this gap by analyzing National Sample Survey data from 524 villages in five states in India. Their analysis seeks to answer two key questions: (1) Who participates in community forestry and what are the determinants of participation? (2) What is the impact of participation on household fuelwood consumption? The authors find that proximity to forests, leadership, and fuelwood dependence are significant factors in explaining village participation in community forestry. Household participation is strongly correlated with scarcity, a result that has implications for a recent policy to expand community forestry from degraded to less degraded forests. The authors'most important findings are that fuelwood consumption and participation are linked, and household participation has a significant positive impact on consumption. However, the presence of a village level forestry institution does not have a direct effect.Community Development and Empowerment,Silviculture,Housing&Human Habitats,Environmental Economics&Policies,Crops&Crop Management Systems,Forestry,Silviculture,Community Development and Empowerment,Environmental Economics&Policies,Housing&Human Habitats

    Forestry data have been included in the global general equilibrium MAGNET model at LEI Wageningen UR. This provides the opportunity to analyse substitution between forestry, natural forests and agriculture with the model, which is essential to analyse biodiversity and greenhouse gas effects of different policies options with respect to feed, food and fuel. The report discusses the background of the GTAP land use database used for the implementation, the way it has been implemented and some first simulation results. The report investigates the weaknesses of the implementation determining a research agenda for further improvements of modeling forestry into the MAGNET model

    The Benefits of Local Forest Recreation in Austria and Its Dependence on Naturalness and Quietude

    The benefits of local recreation in the State-owned forests in Austria (i.e., about 15% of all Austrian forests) are ascertained in this paper. A representative survey of households dealt with their local recreation, perceptions of and disturbances in forests. Total annual benefits of local recreation activities in State-owned forests, such as walking, hiking, cycling and wildlife observation, amount to about EUR 500 per person. Based on the respondents’ valuation of the degree of naturalness and quietude, as well as the options of forest management, the current management increases recreation benefits by EUR 13 per person through increased naturalness, and EUR 1.30 per person and year through increased quietude. Emphasis was placed on the benefits of the current management regime of multifunctional forestry compared to the benefits of a baseline scenario that was drafted specifically for this study, assuming higher levels of lumbering up to the limits allowed by existing nature conservation and forestry laws. The results suggest that forest management has a higher impact on recreational benefits through the naturalness of forests than through reducing artificial noise. A more sustainable forest management could further increase the benefits people derive from both naturalness and lower levels of artificial noise

    The internet revolution: opportunities for tourism and forestry

    Get PDF
    This paper highlights the potential of the Internet for forestry and tourism, with special emphasis on ecotourism. The paper discusses some of the issues involved in developing forestry and ecotourism information resources on the Internet. The justification which underpins the paper (especially in its discussion of ecotourism) is that sustainable management of New Zealand’s biological resources, including its forests, entails their use for tourism purposes; but that such tourism must be ecologically sensitive and responsible

    The role of university forests in education, scientific research and social services at Beijing Forestry University, p. r. China

    Get PDF
    University forests are very important in academic forestry education. They are not only used for the in-forest teaching but also serve for scientific research and public education for people to gain knowledge of forests. Besides these functions, the university forests can also provide social services, such as camping and recreation. People can go into the university forests to enjoy the nature and relax. Taking Beijing Forestry University as an example, this paper will describe the system of university forests in China, their categories, and their roles in forestry education, research and social services. Furthermore, this paper will also explain the development and management system of university forests, and key challenges to the university forests in the future

    Optimal Timber Utilisation Strategies for Wik People on Cape York Peninsula

    Get PDF
    A forestry industry based on the native Darwin stringybark forests of Cape York Peninsula has been identified as a potential generator of employment and income for Wik people. Information appropriate for examining potential Wik timber utilisation strategies is scarce, necessitating primary data collection activities in north Queensland. A mixed-integer, single-period goal program is developed to produce a suite of ‘optimal’ timber utilisation strategies from the perspective of Wik people. Optimal forestry strategies predicted by the goal programming model are financially viable and suggest, in general, that relatively low-technology forestry activities are likely to best satisfy Wik forestry objectives
