    Recent interest in sustainable forest management planning coincides with increased public awareness of climate change. This thesis examined how strategic forestry plans for the Champagne and Aishihik First Nations Traditional Territory in the Yukon are incorporating climate change. A climate-driven, large-scale spruce bark beetle disturbance in the area has been driving forest management planning. However, climate change considerations have not been directly addressed in the planning process. This study identified 24 adaptation options for implementing in forest development areas to achieve regional goals of forest management across three scenarios of climate change. In addition, the performance of alternative strategies to re-establish forests was assessed. Management policies and practices that adapt to climate change were identified and a typology was proposed for classifying sustainable forest management plans according to how they address and manage climate change risks. The plans incorporate best management practices for sustainable forest management that are consistent with climate adaptation responses. A structured decision making (SDM) approach showed that forestry planning processes have yet to come to terms with the risks that climate change may pose to the ability of forest managers to achieve the stated goals and objectives of sustainable forest management plans.

  4. Forest Management Challenges for Sustaining Water Resources in the Anthropocene

    2016-03-01

    Full Text Available The Earth has entered the Anthropocene epoch that is dominated by humans who demand unprecedented quantities of goods and services from forests. The science of forest hydrology and watershed management generated during the past century provides a basic understanding of relationships among forests and water and offers management principles that maximize the benefits of forests for people while sustaining watershed ecosystems. However, the rapid pace of changes in climate, disturbance regimes, invasive species, human population growth, and land use expected in the 21st century is likely to create substantial challenges for watershed management that may require new approaches, models, and best management practices. These challenges are likely to be complex and large scale, involving a combination of direct and indirect biophysical watershed responses, as well as socioeconomic impacts and feedbacks. We discuss the complex relationships between forests and water in a rapidly changing environment, examine the trade-offs and conflicts between water and other resources, and propose new management approaches for sustaining water resources in the Anthropocene.

    Over the past 20 years, Participatory Forest Management (PFM) has become a dominant forest management strategy in Tanzania, covering more than 4.1 million hectares. Sustainable forest use and supply of wood products to local people are major aims of PFM. This paper assesses the sustainability...... of forest utilisation under PFM, using estimates of forest condition and extraction rates based on forest inventories and 480 household surveys from 12 forests; seven under Community Based Forest Management (CBFM), three under Joint Forest Management (JFM) and two under government management (non......-PFM). Extraction of products is intense in forests close to Dar es Salaam, regardless of management regime. Further from Dar es Salaam, harvesting levels in forests under PFM are, with one prominent exception, broadly sustainable. Using GIS data from 116 wards, it is shown that half of the PFM forests in Tanzania...

    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 Based on theoretical underpinnings and an empirical review of forest laws and regulations of selected countries throughout the Americas, we examine key components of natural forest management and how they are addressed in the legal frameworks of Argentina, Brazil, Chile, Costa Rica, Guatemala, Nicaragua, Paraguay, Uruguay, and the U.S. We consider forest policy directives in terms of legislative, planning, operational, environmental/ecological, social, and economic aspects and classify them by the type of policy obligation: (1 non-discretionary laws or rules; or (2 discretionary, voluntary directives; and, further, by the type of policy approach: (1 a specific technology or practice required or recommended; (2 a process or system requirement or recommendation; or (3 a performance or outcome based requirement or recommendation. Protection of at-risk species and riparian buffers are required in all countries and include specific prescriptions in most; forest management planning and secure, legal land title or tenancy are commonly required; and mandatory processes to protect soil and water quality are customary. Less common requirements include forest monitoring and social and economic aspects, and, when in place, they are usually voluntary. Implications for improved policies to achieve sustainable forest management (SFM are discussed.

  15. Evolution of Sustainability in American Forest Resource Management Planning in the Context of the American Forest Management Textbook

    Directory of Open Access Journals (Sweden)

    Thomas J. Straka

    2009-10-01

    Full Text Available American forest resource management and planning goes back to the European roots of American Forestry. Timber management plans, documents based on forest regulation for timber production, were the foundation of American forestry. These types of management plans predominated until World War II. Multiple use forestry developed after World War II and issues like recreation, wildlife, water quality, and wilderness became more important. In the 1970’s harvest scheduling became part of the planning process, allowing for optimization of multiple goals. By 2001 social, environmental, and economic goals were integrated into the timber production process. American forestry experienced distinct historical periods of resource planning, ranging from classic sustained yield timber production, to multiple use-sustained yield, to sustainable human-forest systems. This article traces the historical changes in forest management planning philosophy using the forest management textbooks of the time. These textbooks provide insight into the thought process of the forestry profession as changes in the concept of sustainability occurred.

    Makundi, Willy R.

    1997-12-31

    In this paper, sustainable forest management is discussed within the historical and theoretical framework of the sustainable development debate. The various criteria and indicators for sustainable forest management put forth by different institutions are critically explored. Specific types of climate change mitigation policies/projects in the forest sector are identified and examined in the light of the general criteria for sustainable forest management. Areas of compatibility and contradiction between the climate mitigation objectives and the minimum criteria for sustainable forest management are identified and discussed. Emphasis is put on the problems of monitoring and verifying carbon benefits associated with such projects given their impacts on pre-existing policy objectives on sustainable forest management. The implications of such policy interactions on assignment of carbon credits from forest projects under Joint Implementation/Activities Implemented Jointly initiatives are discussed. The paper concludes that a comprehensive monitoring and verification regime must include an impact assessment on the criteria covered under other agreements such as the Biodiversity and/or Desertification Conventions. The actual carbon credit assigned to a specific project should at least take into account the negative impacts on the criteria for sustainable forest management. The value of the impacts and/or the procedure to evaluate them need to be established by interested parties such as the Councils of the respective Conventions.

    Model forests are nongovernmental organizations at local, regional and international level which are mainly focused on reconciling the conflicts between the stakeholders. This is an innovative approach to organization, which has been receiving more and more attraction from increasing number of countries, which gradually increased the number of model forests for the last 25 years. If these organizations reach desired levels of structure, medium, impacts and assets their contribution in sustainable forest resources management will increase ipso facto. The very first model forest of Turkey was created in Yalova Province in 2010. Yalova Province has certain fundamental problems including but not limited to; population growth and unplanned urbanization caused by industrialization, uncontrolled increase in demand for fire wood and non-wooden products of forestry resources, questionable resource management decisions adopted in the past and low-income levels of the people especially those in the rural areas. The main objective of present case study is to analyze Yalova Model Forest (YMF) so as to determine the possible problems that may occur during implementation of sustainable management for forestry resources through a planning approach with multiple stakeholders. As a result of research, it has been revealed that YMF has certain significant structural, environmental and impact-related problems. In order to ensure continuity of YMF's contribution to sustainable forestry resources management, these problems need to be addressed promptly. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

    2014-01-01

    Full Text Available The forest cover of Serbia occupies around 29% of its territory, which puts it among fairly well wooded countries in Europe. The forests of Serbia are characterized by both state and private forests, medium preservation status, i.e. 27% of area that is covered by insufficiently stocked stands. Coppice forests cover about 50% of the area, and private forests are additionally burdened by fragmented plots. Forest management planning in Serbia is older than 200 years (The Plan of Deliblato Sands Afforestation 1806. There are two basic assumptions that define forest management planning: sustainability and multifunctionality. Today, forest management planning in Serbia is regulated by the Law on forests and it has the characteristics of a system. The planning also has the characteristics of an integral, integrated and adaptive system. The latter is particularly important in terms of pronounced climatic changes. For the forests in protected objects of nature, there are also other types of plans that complement sector plans in forestry (e.g. management plans in protected areas.

  6. The Waswanipi Cree Model Forest: Demonstrating Aboriginal leadership in sustainable forest management

    Energy Technology Data Exchange (ETDEWEB)

    Jolly, A.

    1999-09-01

    Experiences of the Waswanipi Cree community in being partners in sustainable forest management are discussed. The Waswanipi Cree Model Forest was designated as such in 1997. Since then, it has come to be seen as a forum for the community to express its needs, goals and objectives for the future, and as the first opportunity for the Cree community to exercise leadership and decision-making authority related to land management issues. The Waswanipi land is situated on the southernmost tip of eastern James Bay. It extends to some 35,000 sq km, divided into 52 family hunting territories, called traplines. Each trapline has a designated custodian, who is responsible for ensuring that wildlife is harvested in a sustainable manner. Community life is organized around the traplines, although families will sometimes temporarily relocate close to paid employment opportunities. Nevertheless, the purpose of employment is always to return to the bush, with sufficient materials and supplies to last the hunting and trapping season. Prior to the designation of the Model Forest, the major problems have been the rate and extent of forestry activities on Cree land by outside timber companies, the absence of opportunities for the Cree to have a meaningful role in decisions that impacted their future and the difficulties of convincing government experts and forestry companies to allow the Cree to bring their experience-based knowledge to bear on forest resource management issues. The manner in which the new partnership resulting from the designation of the Model Forest is opening the way to better understanding, mitigation of the negative effects of forestry operations on traplines, mediation of conflicts between trappers and forestry companies with timber licences on Waswanipi land, are described as one of the major achievements of the Model Forest Program. The rate and extent of cutting continues to be a problem, however, there are signs of a growing understanding among the timber

  8. 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

  10. Experts’ Analysis of the Quality and Usability of SILVANET Software for Informing Sustainable Forest Management

    Directory of Open Access Journals (Sweden)

    Jose Eugenio Martínez-Falero

    2017-07-01

    Full Text Available It is important today to take account of the opinions of both experts and stakeholders in the sustainable management of forests. SILVANET (Universidad Politécnica de Madrid, Madrid, Spain is a software package that offers a useful methodology for assessing the preferences of individuals or groups, and applying them to the design of a sustainable forest management plan. The program starts by identifying the personal preferences of the evaluators based on information provided individually when comparing and selecting sustainability options from a series of site pairs. The evaluator is given information on certain sustainability indicators obtained in the area to be assessed. The scope of the evaluator’s knowledge of sustainable forest management and the consistency of his/her decisions is assessed, and he/she is then included in a group of people with similar systems of preferences to encourage interaction between evaluators in the same group. The preferences are characterized by matrices that encode individual assessments, the maximization of their utility and the analysis of past decisions. Finally, by identifying preferences, we are able to design the forest management system that maximizes the concept of sustainability for each individual or group of individuals. In this paper, we present the results of its application to mono-specific conifer forest stands, although it can be adapted to other forest types. The forestry management experts classify its usability as good, although non-expert users give it a lower rating.

    2018-01-15

    This paper presents a methodology to elicit the preferences of any individual in the assessment of sustainable forest management at the stand level. The elicitation procedure was based on the comparison of the sustainability of pairs of forest locations. A sustainability map of the whole territory was obtained according to the individual's preferences. Three forest sustainability indicators were pre-calculated for each point in a study area in a Scots pine forest in the National Park of Sierra de Guadarrama in the Madrid Region in Spain to obtain the best management plan with the sustainability map. We followed a participatory process involving fifty people to assess the sustainability of the forest management and the methodology. The results highlighted the demand for conservative forest management, the usefulness of the methodology for managers, and the importance and necessity of incorporating stakeholders into forestry decision-making processes.

  12. Sustainable Forest Management and Carbon in Tropical Latin America: The Case for REDD+

    Directory of Open Access Journals (Sweden)

    Sven Wunder

    2011-02-01

    Full Text Available In this review paper, we assess the economical, governance, and technical conditions that shape forest management in tropical Latin America with particular regard to efforts to reduce forest-based carbon emissions. We provide a framework for discussions about ways to improve forest management that achieve environmental objectives while promoting local and national development and contributing to local livelihoods. We argue that many management practices that lead towards sustainability are only likely to be adopted where there is good governance backed by financial incentives for effective enforcement of management regulations. We propose some policy interventions designed to lower net greenhouse gas emissions by decreasing rates of forest degradation and increasing carbon stock recovery in logged-over or otherwise degraded forests. Implementation of REDD+ could provide critical compensation to forest users for improved management practices in the absence of, or in combination with other economic incentives.

  13. The sustainable management and protection of forests: analysis of the current position globally.

    Science.gov (United States)

    Freer-Smith, Peter; Carnus, Jean-Michel

    2008-06-01

    The loss of forest area globally due to change of land use, the importance of forests in the conservation of biodiversity and in carbon and other biogeochemical cycles, together with the threat to forests from pollution and from the impacts of climate change, place forestry policy and practice at the center of global environmental and sustainability strategy. Forests provide important economic, environmental, social, and cultural benefits, so that in forestry, as in other areas of environmental policy and management, there are tensions between economic development and environmental protection. In this article we review the current information on global forest cover and condition, examine the international processes that relate to forest protection and to sustainable forest management, and look at the main forest certification schemes. We consider the link between the international processes and certification schemes and also their combined effectiveness. We conclude that in some regions of the world neither mechanism is achieving forest protection, while in others local or regional implementation is occurring and is having a significant impact. Choice of certification scheme and implementation of management standards are often influenced by a consideration of the associated costs, and there are some major issues over the monitoring of agreed actions and of the criteria and indicators of sustainability. There are currently a number of initiatives seeking to improve the operation of the international forestry framework (e.g., The Montreal Process, the Ministerial Convention of the Protection of Forests in Europe and European Union actions in Europe, the African Timber Organisation and International Tropical Timber Organisation initiative for African tropical forest, and the development of a worldwide voluntary agreement on forestry in the United Nations Forum on Forests). We suggest that there is a need to improve the connections between scientific understanding

    Even-aged forest management with natural regeneration under continuous cover (i.e. close to nature management) is considered to be sustainable regarding the yield, biodiversity and stability of forest ecosystems. Recently, in the context of climate change, there is a raising question of sustainable forest management regarding carbon uptake. Aim of this research was to explore whether current close to nature forest management approach in Croatia can be considered sustainable in terms of carbon uptake throughout the life-time of Pedunculate oak forest. In state-owned managed forest a chronosequence experiment was set up and carbon stocks in main ecosystem pools (live biomass, dead wood, litter and mineral soil layer), main carbon fluxes (net primary production, soil respiration (SR), decomposition) and net ecosystem productivity were estimated in eight stands of different age (5, 13, 38, 53, 68, 108, 138 and 168 years) based on field measurements and published data. Air and soil temperature and soil moisture were recorded on 7 automatic mini-meteorological stations and weekly SR measurements were used to parameterize SR model. Carbon balance was estimated at weekly scale for the growing season 2011 (there was no harvesting), as well as throughout the normal rotation period of 140 years (harvesting was included). Carbon stocks in different ecosystem pools change during a stand development. Carbon stocks in forest floor increase with stand age, while carbon stocks in dead wood are highest in young and older stands, and lowest in middle-aged, mature stands. Carbon stocks in mineral soil layer were found to be stable across chronosequence with no statistically significant age-dependent trend. Pedunculate Oak stand, assuming successful regeneration, becomes carbon sink very early in a development phase, between the age of 5 and 13 years, and remains carbon sink even after the age of 160 years. Greatest carbon sink was reached in the stand aged 53 years. Obtained results

    Full Text Available Biodiversity and forest management are analyzed for a 500 ha privately owned forest within the Natura 2000 area “ROSCI0122 Muntii Fagaras”. Habitat types and indicator species are identified to measure environmental quality. Working towards an integrated approach to conservation, a range of options that will result in sustainable forest management are then considered. For beech forests light heterogeneity emerges as a crucial management target to ensure tree species richness and structural diversity as a basis for saving indicator species such as Morimus funereus, Cucujus cinnaberinus, Bolitophagus reticulatus and Xestobium austriacum. For spruce forests thinning over a broad range of diameters and maintenance of veteran trees would provide habitats for indicator species such asOlisthaerus substriatus. The populations of a number of bird species would be increased by strip-harvesting slopes: species such as Tetrao urogallus, Bonasia bonasia and Ficedula parva prefer forest margins. Steep slopes, and the areas around springs and watercourses, as well as rock faces, should remain unmanaged. Future management should start with a grid-based inventory to create an objective database of forest structure and life. An example is presented for high-elevation spruce forest. The inventory should quantify the variations in diameter, height and volume of trees per unit area. Such data would allow the advanced planning of forest operations.

  2. Balancing the Relationship Between Protection and Sustainable Management in Canada′s Boreal Forest

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Protection and sustainable forest management are related but unique, with protection focusing on minimising risk to ecosystems and sustainable management emphasising economic development. Given these distinct roles, a defining characteristic of the relationship between the two approaches is their relative abundance and distribution. The relationship is currently imbalanced, with only 12% of Canada allocated to protection, indicating that ecological values have historically been traded off in favour of resource production. The intactness of Canada′s boreal forest provides an opportunity for a more holistic approach that conserves its globally significant environmental attributes while also supporting resource production. The Boreal Forest Conservation Framework proposes a balanced relationship that allocates land approximately equally between protection and sustainable management. It is a framework that has been endorsed by industry, Aboriginal, and conservation organisations, and is supported by conservation science. Recent commitments to comprehensive land-use planning at regional scales are consistent with the collaborative approach promoted by the Boreal Forest Conservation Framework, and suggest that conservation objectives are likely to receive increased attention in Canada′s boreal region relative to recent history. Ensuring that land-use planning is proactive and balanced will be essential to forging a cooperative relationship between sustainable management and protection in the region.

  3. EO Underpinning the Quality of Ecosystem Services with Geospatial Data- The Case of Sustainable Forest Management

    Science.gov (United States)

    Crosthwaite Eyre, Charles

    2010-12-01

    Payments for Ecosystem Services (PES) is an exciting and expanding opportunity for sustainably managed forests. PES are derived from a range of ecosystem benefits from forests including climate change mitigation through afforestation and avoided deforestation, green power generation, wetland and watershed rehabilitation, water quality improvement, marine flood defence and the reduction in desertification and soil erosion. Forests are also the ancestral home to many vulnerable communities which need protection. Sustainable forest management plays a key role in many of these services which generates a potentially critical source of finance. However, for forests to realise revenues from these PES, they must meet demanding standards of project validation and service verification. They also need geospatial data to manage and monitor operational risk. In many cases the data is difficult to collect on the ground - in some cases impossible. This will create a new demand for data that must be impartial, timely, area wide, accurate and cost effective. This presentation will highlight the unique capacity of EO to provide these geospatial inputs required in the generation of PES from forestry and demonstrate products with practical examples.

In the 1970’s harvest scheduling became part of the planning...

  5. Carbon sequestration, biological diversity, and sustainable development: Integrated forest management

    Science.gov (United States)

    Cairns, Michael A.; Meganck, Richard A.

    1994-01-01

    Tropical deforestation provides a significant contribution to anthropogenic increases in atmospheric CO2 concentration that may lead to global warming. Forestation and other forest management options to sequester CO2 in the tropical latitudes may fail unless they address local economic, social, environmental, and political needs of people in the developing world. Forest management is discussed in terms of three objectives: carbon sequestration, sustainable development, and biodiversity conservation. An integrated forest management strategy of land-use planning is proposed to achieve these objectives and is centered around: preservation of primary forest, intensified use of nontimber resources, agroforestry, and selective use of plantation forestry.

  6. Assisting Sustainable Forest Management and Forest Policy Planning with the Sim4Tree Decision Support System

    Directory of Open Access Journals (Sweden)

    Floris Dalemans

    2015-03-01

    Full Text Available As European forest policy increasingly focuses on multiple ecosystem services and participatory decision making, forest managers and policy planners have a need for integrated, user-friendly, broad spectrum decision support systems (DSS that address risks and uncertainties, such as climate change, in a robust way and that provide credible advice in a transparent manner, enabling effective stakeholder involvement. The Sim4Tree DSS has been accordingly developed as a user-oriented, modular and multipurpose toolbox. Sim4Tree supports strategic and tactical forestry planning by providing simulations of forest development, ecosystem services potential and economic performance through time, from a regional to a stand scale, under various management and climate regimes. Sim4Tree allows comparing the performance of different scenarios with regard to diverse criteria so as to optimize management choices. This paper explains the concept, characteristics, functionalities, components and use of the current Sim4Tree DSS v2.5, which was parameterized for the region of Flanders, Belgium, but can be flexibly adapted to allow a broader use. When considering the current challenges for forestry DSS, an effort has been made towards the participatory component and towards integration, while the lack of robustness remains Sim4Tree’s weakest point. However, its structural flexibility allows many possibilities for future improvement and extension.

    2013-03-01

    This paper analyzes how sustained yield (SY) forestry is defined and implemented in Sweden and Russia, two countries with different forest-industrial regimes. We first compare definitions of SY forestry in national legislation and policies. Then we study forest management planning in two large forest management units with respect to: delivered forest products and values, how the harvest level of timber is defined, where the harvest takes place, and what treatments are used to sustain desired forest products and values. In Sweden SY forestry is maximum yield based on high-input forest management, and in Russia it is forestry based on natural regeneration with minimum investments in silviculture. We conclude that how SY forestry contributes to SFM depends on the context. Finally, we discuss the consequences of SY forestry as performed in Sweden and Russia related to its ability to support diverse forest functions, as envisioned in sustainable forest management policy.

    2015-01-01

    Background Cumulative impacts of wildfires and forest harvesting can cause shifts from closed-crown forest to open woodland in boreal ecosystems. To lower the probability of occurrence of such catastrophic regime shifts, forest logging must decrease when fire frequency increases, so that the combined disturbance rate does not exceed the Holocene maximum. Knowing how climate warming will affect fire regimes is thus crucial to sustainably manage the forest. This study aimed to provide a guid...

  11. ORGEST: Regional guidelines and silvicultural models for sustainable forest management

    2017-11-01

    Aim of the study: To develop regional guidelines for sustainable forest management. Area of the study: Forests of Catalonia (NE Spain). Material and methods: The process of developing the forest management guidelines (FMG) started by establishing a thorough classification of forest types at stand level. This classification hinges on two attributes: tree species composition and site quality based on ecological variables, which together determine potential productivity. From there, the management guidelines establish certain objectives and silvicultural models for each forest type. The forest type classifications, like the silvicultural models, were produced using both existing and newly-built growth models based on data from the National Forest Inventory (NFI) and expert knowledge. The effort involved over 20 expert working groups in order to better integrate the expertise and vision of different sectorial agents. Main results: The FMG consist in quantitative silvicultural models that include typical silvicultural variables, technical descriptions of treatments and codes of good practice. Guidelines now cover almost all forest types in Catalonia (spanning up to 90% of the Catalan forest area). Different silvicultural models have been developed for pure and mixed stands, different site quality classes (2–3 classes per species), and even- and multi-aged stands. Research highlights: FMG: i) orient the management of private and public forests, (ii) provide a technical scaffold for efficient allocation/investment of public subsidies in forest management, and (iii) bridge forest planning instruments at regional (strategic-tactical) and stand (operational) level.

    2016-03-01

    Full Text Available Forest benefit analysis is vital in ensuring sustainable community-based natural resources management. Forest depletion and degradation are key issues in rural Zimbabwe and strategies to enhance sustainable forest management are continually sought. This study was carried out to assess the impact of forests on communities from Nyanga, Guruve and Zvimba districts of Zimbabwe. It is based on a Big Lottery Fund project implemented by Progressio-UK and Environment Africa. Itfocuses on identifying replicable community forest and landmanagement strategies and the level of benefits accruing to the community. Analysis of change was based on the Income and Food Security and Forest benefits, which also constitutes the tools used during the research. The study confirms the high rate of deforestation and the increased realisation by communities to initiate practical measures aimed at protecting and sustaining forest and land resources from which they derive economic and social benefits. The results highlight the value of community structures (Farmer Field Schools and Environmental Action Groups as conduits for natural resource management. The interconnectivity among forests, agricultural systems and the integral role of people are recognised as key to climate change adaptation.Keywords: Forest benefits; sustainability,;livelihoods; farmer field schools

  13. Consequences of More Intensive Forestry for the Sustainable Management of Forest Soils and Waters

    Directory of Open Access Journals (Sweden)

    Eva Ring

    2011-02-01

    Full Text Available Additions of nutrients, faster growing tree varieties, more intense harvest practices, and a changing climate all have the potential to increase forest production in Sweden, thereby mitigating climate change through carbon sequestration and fossil fuel substitution. However, the effects of management strategies for increased biomass production on soil resources and water quality at landscape scales are inadequately understood. Key knowledge gaps also remain regarding the sustainability of shorter rotation periods and more intensive biomass harvests. This includes effects of fertilization on the long-term weathering and supply of base cations and the consequences of changing mineral availability for future forest production. Furthermore, because soils and surface waters are closely connected, management efforts in the terrestrial landscape will potentially have consequences for water quality and the ecology of streams, rivers, and lakes. Here, we review and discuss some of the most pertinent questions related to how increased forest biomass production in Sweden could affect soils and surface waters, and how contemporary forestry goals can be met while minimizing the loss of other ecosystem services. We suggest that the development of management plans to promote the sustainable use of soil resources and water quality, while maximizing biomass production, will require a holistic ecosystem approach that is placed within a broader landscape perspective.

  15. 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.

  16. Forest crimes as a threat to sustainable forest management

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available From ancient times to the present day, forest public relations has been an issue on the agenda. This relationship’s purpose was initially needed for shelter and nutrition; however today this process has changed with urbanization, overpopulation and understanding the new functions of forests. When land ownership became a tool of production, offenses occurred in order to convert forestlands to agricultural lands. So the vast majority of the world’s forests have been lost for this reason. Today, deforestation is occurring in tropical countries that are expecting to gain agricultural area. The purpose of this study is to investigate the relationship between urbanization and the qualitative and quantitative characteristics of forest crimes, which are a major obstacle for sustainable forestry. Although forests cover about 27 % of Turkey’s territory, the forests are losing viability; the status of wood raw material per unit area and the total area of the country in the ratio of productive forests are becoming critical in Turkey. Turkey’s rugged terrain and factors such as human interventions, fires, deforestation for agriculture, illegal cuttings, or improper grazing reduce existing forests or cause deterioration of their structure. In the past, deforestation, as a result of human interventions in Turkey, was done by forest villagers who live in rural areas. The forest crimes depend on various socio-economic reasons and have many adverse effects on the sustainability of forest and forest existence. In developed countries, illegal interventions such as opening, grazing, cutting, occupation, use, settlement, or hunting crimes have been largely eliminated because of the absence of cadastral problems, the existence of more responsive people to protect the environment and forests and a rural population, which has a higher standard of living. In the last 20 years, there has been both a dramatic decrease in the population living in rural areas and a

    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

  19. SUSTAINABLE MANAGEMENT OF NATURAL FORESTS IN PANTANAL REGION, BRAZIL

    Directory of Open Access Journals (Sweden)

    Patricia Póvoa de Mattos

    2010-01-01

    Full Text Available The Pantanal region in Brazil has an area of 140,000 km², with approximately 30 % of natural forests distributed as deciduous, semideciduous, and forested savannas. The subregion of Nhecolandia represents 19 % of this area. There is constant concern about the sustainability of these forested areas, as there is a constant demand for wood for farm maintenance, mainly for making fence poles. The objective of this article is to indicate sustainable forest management practices in the Pantanal region of Nhecolandia. The methodology of this novel approach consisted of the recovery and organization of the available information to calculate the sustainable allowable cut per hectare, considering: cutting cycle, wood stock, periodic annual increment (PAI in percentage of volume from the commercial or interesting species and the stand structure. For forested savannas, the diameter at breast height (DBH of 529 trees per hectare were estimated as follows: 28 % with a DBH lower than 10 cm, 36 % from 10 to 20 cm, 21 % from 20 to 30 cm, 10 % from 30 to 40 cm and only 4 % greater than 40 cm. The estimated total volume per hectare was 84.2 m³ and the estimated basal area was 18.6 m². The forested areas of the Pantanal region present potential for sustainable use. However, due to regional characteristics and the lack of available information, an enhancement in research is recommended to establish a basic management guide to ensure its perpetuation for future generations.

    2014-03-01

    Full Text Available The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO. According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input

    Mumtaz, S; Durr-e-nayab

    1991-01-01

    The terms of access to the resources of the Chaprote forest in the Nagar valley of Northern Pakistan are discussed. The Nagar valley became part of the Federally Administered Areas of Pakistan in 1972. The regime was undergoing political transformation and this resulted in continuous changes in the local requirements, allocation, and access to natural resources. This work examines the concerns of environmentalists, among other issues, in relation to the conservation of finite natural resources and maintaining a symbiosis between regeneration and depletion of renewable natural resources. Subjects covered include: rights to the forest, forest management under government jurisdiction, indigenous systems of forest management, and the effectiveness of management systems compared to local management systems. A comparison is made between communal forestry and commercial forestry with consideration for effective management of the Chaprote forest being the central idea.

  8. Sustainable management in crop monocultures: the impact of retaining forest on oil palm yield.

    2014-01-01

    Tropical agriculture is expanding rapidly at the expense of forest, driving a global extinction crisis. How to create agricultural landscapes that minimise the clearance of forest and maximise sustainability is thus a key issue. One possibility is protecting natural forest within or adjacent to crop monocultures to harness important ecosystem services provided by biodiversity spill-over that may facilitate production. Yet this contrasts with the conflicting potential that the retention of forest exports dis-services, such as agricultural pests. We focus on oil palm and obtained yields from 499 plantation parcels spanning a total of ≈23,000 ha of oil palm plantation in Sabah, Malaysian Borneo. We investigate the relationship between the extent and proximity of both contiguous and fragmented dipterocarp forest cover and oil palm yield, controlling for variation in oil palm age and for environmental heterogeneity by incorporating proximity to non-native forestry plantations, other oil palm plantations, and large rivers, elevation and soil type in our models. The extent of forest cover and proximity to dipterocarp forest were not significant predictors of oil palm yield. Similarly, proximity to large rivers and other oil palm plantations, as well as soil type had no significant effect. Instead, lower elevation and closer proximity to forestry plantations had significant positive impacts on oil palm yield. These findings suggest that if dipterocarp forests are exporting ecosystem service benefits or ecosystem dis-services, that the net effect on yield is neutral. There is thus no evidence to support arguments that forest should be retained within or adjacent to oil palm monocultures for the provision of ecosystem services that benefit yield. We urge for more nuanced assessments of the impacts of forest and biodiversity on yields in crop monocultures to better understand their role in sustainable agriculture.

  14. Forest Policy and Law for Sustainability within the Korean Peninsula

    Directory of Open Access Journals (Sweden)

    Mi Sun Park

    2014-08-01

    Full Text Available Since the early 1990s, sustainable forest management (SFM has emerged as a paradigm of forest management on global, regional and national levels. In developing countries, avoiding deforestation is a preliminary step towards SFM. The Korean peninsula experienced severe deforestation and forest degradation after the Korean War (1950–1953. In the 1970s and 1980s, South Korea achieved forest restoration through the National Greening Program. In contrast, North Korea failed to restore forests in spite of continuous trials with forest restoration plans. In North Korea, deforestation has accelerated since the mid-1980s. Deforestation and forest degradation in North Korea threatens stability throughout the Korean peninsula. This study focuses on comparing the forest policy and laws of South Korea and North Korea and suggesting forest policy that promotes sustainability in the Korean peninsula. The research findings can provide developing countries with significant information on forest policy and laws to avoid deforestation and forest degradation and move towards sustainability.

    2013-07-01

    Aim of study: There is a lack of empirical research that deals with sustainable forest management in Mediterranean regions, among the most vulnerable ecosystems. The main purpose of this work is to define the strategic criteria and objectives for sustainable forest management and aggregate the preferences of stake holders in a Mediterranean region, using AHP and Goal Programming. Area of study: Valencian Community (Spain). Material and Methods: Firstly, we identified forest stake holders and structured a decision hierarchy. Then a workshop was carried out to test and validate the proposed criteria and objectives, as well as a survey to determine social preferences. Secondly, another survey was conducted amongst experts to prioritize action plans. Main results: Stake holders preferences gave the greatest importance to the environmental criteria (hydrological regulation and erosion, climate change mitigation and biodiversity) with an average weight of 40%. Social criteria (employment, recreational activities and landscape) had a weight of 38% and 22% the economic criteria case (wood, hunting and fishing, livestock, renewable energies, rural tourism and mining). The results showed that new products and services such as tourism, renewable energies, landscape, hydrological regulation and erosion control, biodiversity or climate change mitigation are very relevant objectives. We also prioritized action plans comparing them with the distribution of the administration budget. Research highlights: The environmental and social criteria are much more important than the economic ones in the regional planning of the Mediterranean forest, regardless of the method used to aggregate the social preferences and if the forest is public or private.

  16. Measuring biodiversity and sustainable management in forests and agricultural landscapes

    Dudley, Nigel; Baldock, David; Nasi, Robert; Stolton, Sue

    2005-01-01

    Most of the world's biodiversity will continue to exist outside protected areas and there are also managed lands within many protected areas. In the assessment of millennium targets, there is therefore a need for indicators to measure biodiversity and suitability of habitats for biodiversity both across the whole landscape/seascape and in specific managed habitats. The two predominant land uses in many inhabited areas are forestry and agriculture and these are examined. Many national-level criteria and indicator systems already exist that attempt to assess biodiversity in forests and the impacts of forest management, but there is generally less experience in measuring these values in agricultural landscapes. Existing systems are reviewed, both for their usefulness in providing indicators and to assess the extent to which they have been applied. This preliminary gap analysis is used in the development of a set of indicators suitable for measuring progress towards the conservation of biodiversity in managed forests and agriculture. The paper concludes with a draft set of indicators for discussion, with suggestions including proportion of land under sustainable management, amount of produce from such land, area of natural or high quality semi-natural land within landscapes under sustainable management and key indicator species.

    The International Workshop on Sustainable Forest Management: Monitoring and Verification of Greenhouse Gases was held in San Jose, Costa Rica, July 29-31, 1996. The main objectives of the workshop were to: (1) assemble key practitioners of forestry greenhouse gas (GHG) or carbon offset projects, remote sensing of land cover change, guidelines development, and the forest products certification movement, to offer presentations and small group discussions on findings relevant to the crucial need for the development of guidelines for monitoring and verifying offset projects, and (2) disseminate the findings to interested carbon offset project developers and forestry and climate change policy makers, who need guidance and consistency of methods to reduce project transaction costs and increase probable reliability of carbon benefits, at appropriate venues. The workshop brought together about 45 participants from developed, developing, and transition countries. The participants included researchers, government officials, project developers, and staff from regional and international agencies. Each shared his or her perspectives based on experience in the development and use of methods for monitoring and verifying carbon flows from forest areas and projects. A shared sense among the participants was that methods for monitoring forestry projects are well established, and the techniques are known and used extensively, particularly in production forestry. Introducing climate change with its long-term perspective is often in conflict with the shorter-term perspective of most forestry projects and standard accounting principles. The resolution of these conflicts may require national and international agreements among the affected parties. The establishment of guidelines and protocols for better methods that are sensitive to regional issues will be an important first step to increase the credibility of forestry projects as viable mitigation options. The workshop deliberations led

    2015-04-01

    Full Text Available Aim of study: to identify criteria and indicators (C&I of sustainable forest management (SFM under Mediterranean conditions. The indicators are meant to monitor changes in the provision of ecosystem services at a local scale (forest management unit, FMU. We support that if a forest provides a bundle of ecosystem services its management can be considered sustainable; thus, we adjust C&I to an ecosystem services classification. Area of study: La Hunde y La Palomera, a public FMU in the region of Valencia (east of Spain, 100km southwest of the city of Valencia. Material and methods: first, a literature review of the following themes took part: SFM, features of Mediterranean forests, ecosystem services and C&I. Some C&I were proposed and, later on, a participatory process in Ayora, the municipality where the mentioned FMU is located, was carried out with different stakeholders (forestry professionals, users for recreation, hunters, environmentalists and professionals of cultural and rural development activities in order for them to value the C&I proposed according to their management preferences for La Hunde y La Palomera. Research highlights: 15 criteria and 133 indicators were identified: a balance has been achieved among economic, social and ecological concerns. People value the ecological issues associated to forestry on top and the economic ones at the bottom. Results suggest that SFM under Mediterranean conditions is based on more than one product and on the provision of several ecosystem services.

    Full Text Available To pursue the usage of forests resources in the processes of economic and social development it is determining that the principles of natural heritage protection join in a concept of progress, based on evolution and technological innovation; the realization of innovative investigation and representation tools turns out to be useful to ease the integration of forests’ resources in shared development processes aimed at enhancing the cooperation of local actors, and to ease the territory’s sustainable growth and the development of the natural heritage. The integrated management of the actions aimed at protecting and easing the ecologic and recreative functioning of forests, which are increasingly exposed to pressures caused by several catastrophic factors, requires the tuning of modelling and active monitoring systems of the forests based on social networks and volunteering for the processes of data updating.

  3. Small Mushrooms for Big Business? Gaps in the Sustainable Management of Non-Timber Forest Products in Southwest China

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available The challenge of managing forests for the production of commercial non-timber forest products (NTFPs lies in promoting economic development by maintaining and even increasing production while simultaneously maintaining or improving ecological conditions. The discussion of forest management therefore encompasses a wide range of social, economic, political, and ecological questions. Empirically, it is clear that both market and government failure can lead to unsustainable management in commercial NTFP use. How can we manage the market and at the same time formulate good policies? Taking cases from Southwest China, this paper critically examines the current development of NTFP commercialization in the mountainous region of Southwest China. It focuses particularly on three pieces of research on mushroom collection and marketing. By examining empirical data, the paper analyzes current gaps in the policy and the market in mountainous areas in the context of promoting sustainable use of NTFP. It examines the market structure from the perspective of market failure and explores the government’s failure to promote commercial NTFPs. We recommend economic and political decentralization, capacity building, and government investment as means to improve sustainable management.

  13. The Contribution of Forests and Trees to Sustainable Diets

    2013-11-01

    Full Text Available With the growing demands from a population expected to reach 9 billion people by 2050, it is unclear how our current global food system will meet future food needs. Ensuring that all people have access to adequate and nutritious food produced in an environmentally and socio-culturally sustainable manner is one of the greatest challenges of our time. “Sustainable diets” have been proposed as a multidimensional framework to address the need for nutritious and adequate food in the context of the many challenges facing the world today: reducing poverty and hunger, improving environmental health, enhancing human well-being and health, and strengthening local food networks, sustainable livelihoods and cultural heritage. This paper examines the contribution of forests and trees to sustainable diets, covering among others, nutritional, cultural, environmental and provisioning aspects. The literature reviewed highlight major opportunities to strengthen the contribution of forest and tree foods to sustainable diets. However, several constraints need to be removed. They relate to: cultural aspects, sustainable use of non-wood forest products, organization of forest food provisioning, limited knowledge of forest food composition, challenges in adapting management of forests and trees to account for forest foods, and in integrating forest biodiversity into complex landscapes managed for multiple benefits. Finally, the paper identifies research gaps and makes recommendations to enhance the contribution of forest foods to sustainable diets through increased awareness and better integration of information and knowledge on nutritious forest foods into national nutrition strategies and programs.

  14. Significant increase in ecosystem C can be achieved with sustainable forest management in subtropical plantation forests.

    Wei, Xiaohua; Blanco, Juan A

    2014-01-01

    Subtropical planted forests are rapidly expanding. They are traditionally managed for intensive, short-term goals that often lead to long-term yield decline and reduced carbon sequestration capacity. Here we show how it is possible to increase and sustain carbon stored in subtropical forest plantations if management is switched towards more sustainable forestry. We first conducted a literature review to explore possible management factors that contribute to the potentials in ecosystem C in tropical and subtropical plantations. We found that broadleaves plantations have significantly higher ecosystem C than conifer plantations. In addition, ecosystem C increases with plantation age, and reaches a peak with intermediate stand densities of 1500-2500 trees ha⁻¹. We then used the FORECAST model to simulate the regional implications of switching from traditional to sustainable management regimes, using Chinese fir (Cunninghamia lanceolata) plantations in subtropical China as a study case. We randomly simulated 200 traditional short-rotation pure stands and 200 sustainably-managed mixed Chinese fir--Phoebe bournei plantations, for 120 years. Our results showed that mixed, sustainably-managed plantations have on average 67.5% more ecosystem C than traditional pure conifer plantations. If all pure plantations were gradually transformed into mixed plantations during the next 10 years, carbon stocks could rise in 2050 by 260.22 TgC in east-central China. Assuming similar differences for temperate and boreal plantations, if sustainable forestry practices were applied to all new forest plantation types in China, stored carbon could increase by 1,482.80 TgC in 2050. Such an increase would be equivalent to a yearly sequestration rate of 40.08 TgC yr⁻¹, offsetting 1.9% of China's annual emissions in 2010. More importantly, this C increase can be sustained in the long term through the maintenance of higher amounts of soil organic carbon and the production of timber products

More importantly, this C increase can be sustained in the long term through the maintenance of higher amounts of soil organic carbon and the production

    2015-05-01

    Full Text Available Background Cumulative impacts of wildfires and forest harvesting can cause shifts from closed-crown forest to open woodland in boreal ecosystems. To lower the probability of occurrence of such catastrophic regime shifts, forest logging must decrease when fire frequency increases, so that the combined disturbance rate does not exceed the Holocene maximum. Knowing how climate warming will affect fire regimes is thus crucial to sustainably manage the forest. This study aimed to provide a guide to determine sustainable forest harvesting levels, by reconstructing the Holocene fire history at the northern limit of commercial forestry in Quebec using charcoal particles preserved in lake sediments. Methods Sediment cores were sampled from four lakes located close to the northern limit of commercial forestry in Quebec. The cores were sliced into consecutive 0.5 cm thick subsamples from which 1 cm3 was extracted to count and measure charcoal particles larger than 150 microns. Age-depth models were obtained for each core based on accelerator mass spectroscopy (AMS radiocarbon dates. Holocene fire histories were reconstructed by combining charcoal counts and age-depth models to obtain charcoal accumulation rates and, after statistical treatment, long-term trends in fire occurrence (expressed as number of fires per 1000 years. Results Fire occurrence varied between the four studied sites, but fires generally occurred more often during warm and dry periods of the Holocene, especially during the Holocene Thermal Maximum (7000–3500 cal. BP, when fire occurrence was twice as high as at present. Conclusions The current fire regime in the study area is still within the natural range of variability observed over the Holocene. However, climatic conditions comparable to the Holocene Thermal Maximum could be reached within the next few decades, thus substantially reducing the amount of wood available to the forest industry.

    2017-01-01

    Full Text Available Forest management planning focusing on sustainable supply of forest-based services such as wood and Non-Wood Forest Products (NWFPs is important for the sustainability of forest ecosystems over time. This study explores the development of a mushroom integrated decision support system (ETÇAPOptimization for multiple use forest management planning and for the analysis of long-term effects of different forest management scenarios on the joint production of timber and mushroom. The Decision Support System (DSS integrates both mushroom and timber production derived from the same forest ecosystem using empirical models for mushroom occurrence and yield as well as for tree growth. The DSS takes further into account the spatial distribution and productivity models of Lactarius deliciosus and Lactarius salmonicolor generated for the Kızılcasu Planning unit in Northwest Turkey. Six different forest management scenarios were considered, each with a different set of objectives, e.g., maximization of both the amount and the income from timber or mushroom production. Some scenarios include further timber even flow constraints (10% fluctuation. The Net Present Value (NPV and the amount of timber and of mushroom production were used as performance indicators to discuss and elaborate on forest dynamics under different management scenarios. The results indicated that forest management planning strategies to address the maximization of NPV from mushroom production scenarios are characterized by substantial decreases in total income from the forest due mainly to the conservation of forest areas to favor mushroom production. On the other hand, the integration of regulatory constraints into forest management plans lead to a substantial decrease of both the economic profit and the amount of forest ecosystem services, e.g., timber and mushroom. The results showed that the NPV from mushroom production can be two to three times higher than the NPV from timber

    Lichens are a bottleneck resource for circumpolar populations of reindeer, and as such, for reindeer husbandry as an indigenous Sami land-use tradition in northern Sweden. This study uses ground lichen data and forest information collected within the Swedish National Forest Inventory since 1953, on the scale of northern Sweden. We found a 71 % decline in the area of lichen-abundant forests over the last 60 years. A decline was observed in all regions and age classes and especially coincided with a decrease of >60 year old, open pine forests, which was the primary explanatory factor in our model. The effects of reindeer numbers were inconclusive in explaining the decrease in lichen-abundant forest. The role that forestry has played in causing this decline can be debated, but forestry can have a significant role in reversing the trend and improving ground lichen conditions.

  2. Interpreting Sustainability for Urban Forests

    2010-06-01

    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

    1997-01-01

    This article focuses on deforestation and women's participation in environmental development. Deforestation substantially contributes to accelerated changes in global climates and robs the world of irreplaceable biodiversity. Approximately 100 million hectares of forests have been lost throughout the world since 1950, with the world losing up to 20.4 million hectares of tropical forests annually. Moreover, women's participation in environmental development is currently impeded by many factors such as problems of land tenure and ownership. In order to have a balance between greater productivity and environmental protection, policymakers should ensure that agricultural and forestry extension services are designed incorporating a balanced gender perspective, including women's full participation in decision-making fora, and building upon their knowledge of community concerns. This article further cited examples of women's participation in several countries and identified eight steps to incorporate women in project design.

    Korea, China, Japan and Canada are all members of the Montreal Process (MP). However, there has been little comparative research on the public awareness of forest values within the framework of Sustainable Forest Management, not only between Asia and Canada, but also among these three Asian countries. This is true of aesthetic values, especially as the MP framework has no indicator for aesthetic values. We conducted surveys to identify similarities and differences in the perceptions of various forest values, including aesthetic values, between residents of the four countries: university student groups in Korea, China, Japan and Canada, as well as a more detailed assessment of the attitudes of Koreans by including two additional groups, Korean office workers, and Koreans living in Canada. A multivariate analysis of variance test across the four university student groups revealed significant differences in the rating of six forest functions out of 31. However the same test across the three Korean groups indicated no significant differences indicating higher confidence in the generalizability of our university student comparisons. For the forest aesthetic values, an analysis of variance test showed no significant differences across all groups. The forest aesthetic value was rated 6.95 to 7.98 (out of 10.0) depending on the group and rated relatively highly among ten social values across all the groups. Thurstone scale rankings and relative distances of six major forest values indicated that climate change control was ranked as the highest priority and scenic beauty was ranked the lowest by all the groups. Comparison tests of the frequencies of preferred major forest values revealed no significant differences across the groups with the exception of the Japanese group. These results suggest that public awareness of aesthetic and other forest values are not clearly correlated with the cultural backgrounds of the individuals, and the Korean university students' awareness

    Guyana officials were certain that an efficient forest management could yield economic benefits to the country, while still allowing for the sustainability of its forest resources. Standards will be set in a Code of Practice (COP). Lectures, presented in the proceeding, were mixed with group discussions and finally the 26 participants gave their written view of `What has to be done in Guyana and by whom?`. Amerindians wanted their own foresters should be recruited to oversee the activities on their own land. Bushmilling need to be controlled but not banned. Monitoring timber products and control of hunting should be stricter. COP should set standards for the residual stand. Environmental Protection Agency wanted more research and training, with aim of self-monitoring capability for forest users. Forest Products Association recommended government to co-operate for refinement of: training, mapping of resources, harvesting plans, concession agreements, road building, and bushmilling. Forestry Commission wanted concession allocation procedures to be reviewed: zonation of chainsaw activities, protection of small-scale operators, management plans. COP should be revised and tested in practice. Suggestion about standards for residual stand should be considered. ORGUT Lecturers recommended a standard for residual stand, a vertical and horizontal spot density measure. Based on that the concession holder could harvest what, where and when be preferred and chose the most efficient technique

    2014-01-01

    Full Text Available Local success stories of sustainable forest management can inspire scientists and decision-makers. This article analyses the traditional ′Adat′ institution that plays a role in the management of Grand Forest Park ′Herman Yohannes′, in the Western part of Timor where the Adat forest management regulation has been formally restored. The original set of design principles for sustainable management of common pool resources of Elinor Ostrom (1990 has been used in this study as an analytical framework for understanding the role of the Adat institution in respect to the forest. In the park, the local community applies Adat for protection and management of the forest that has been its home for centuries. It appears that Ostrom′s design principles can be identified in the current Adat institution and play a role in the sustainable management of the forest. Although many other variables can lead to success or failure of institutions, the original (internal design principles are still valuable as a practical tool for building institutions that are - under certain conditions - able to sustain common pool resources. The findings confirm the importance of traditional institutions in successful forest management. The study recommends that decision-makers take into account existing traditional management systems that have shown long term functionality.

    Mountain ecosystems are extremely vulnerable to climate change. The real potential for adaptation depends upon the existence of a wide genetic diversity in trees populations, upon the adaptive genetic variation, respectively. Genetic diversity offers the guarantee that forest species can survive, adapt and evolve under the influence of changing environmental conditions. The aim of this study is to evaluate the genetic diversity and adaptive genetic potential of two local species - Norway spruce and European silver fir - in the context of regional climate change. Based on data from a long-term provenance experiments network and climate variables spanning over more than 50 years, we have investigated the impact of climatic factors on growth performance and adaptation of tree species. Our results indicate that climatic and geographic factors significantly affect forest site productivity. Mean annual temperature and annual precipitation amount were found to be statistically significant explanatory variables. Combining the additive genetic model with the analysis of nuclear markers we obtained different images of the genetic structure of tree populations. As genetic indicators we used: gene frequencies, genetic diversity, genetic differentiation, genetic variance, plasticity. Spatial genetic analyses have allowed identifying the genetic centers holding high genetic diversity which will be valuable sources of gene able to buffer the negative effects of future climate change. Correlations between the marginal populations and in the optimal vegetation, between the level of genetic diversity and ecosystem stability, will allow the assessment of future risks arising from current genetic structure. Therefore, the strategies for sustainable forest management have to rely on the adaptive genetic variation and local adaptation of the valuable genetic resources. This work was realized within the framework of the project GENCLIM (Evaluating the adaptive potential of the main

Some actions were initiated by national Governments and the European Union, like Nature 2000 Network and Sustainable Forest Management. Pursuing the above EU targets, the administration of the Latium region (central Italy has issued several acts with the aim of creating a system of protected areas where the main focus for silvicultural activities is on biodiversity conservation and the preservation of multi-functionality of forests. Priority of forest planning activities and financing has been given to main habitats and species, sensu 92/43/CEE and 79/409/CEE European Directives. The Nature 2000 Network and the regional offices of Forestry and Protected Areas worked together to increase the forest managed areas, to apply the SFM (Sustainable Forest Management practices and to promote local community development. The Forest Conservation Area, with the help of EU Funds, is financing a Forest Management Plan in Nature 2000 sites and protected areas. The offices for Protected Areas and Nature 2000 Network are working to simplify the administrative procedures for logging in special Protected areas and in forest habitats with no specific conservation priority.

    Full Text Available The relationship between protected areas and forest management has been one that has often been fraught with conflict. New practices in the forest sector and new ecological insights have led more recently to better co-operation in some regions, although it is debatable to what extent cooperative approaches are desirable. In this introduction to the special section on the relationships between protected areas and sustainable forest management, we outline the history of the forestry and protected areas sectors in Canada, and the evolution of the relationships between them. We define key terms for the debate and offer a novel framework for understanding the relationship between the two sectors as management regimes that occur along parallel continua of sustainability. This framework is contrasted against real-world findings from across Canada, and with examples from elsewhere in the world.

    2015-09-01

    Full Text Available Nowadays, deforestation of territories and degradation of forest resources is a global problem as it leads to a climate change, soil degradation, the decline in natural reproduction of forest resources and to the disappearance of many valuable species of forest cultures. Due to the importance of the preservation of forest resources for environment it is necessary to revise the conceptual approach to the reflection of such resources both at the micro- and at the macroeconomic level. Preservation, rational use and reproduction of forest resources is one of the priorities of forestry development inUkraine. Accounting is a tool which allows to form the information about the condition and availability of forest resources. In this regard, we consider that the accounting information is an important tool for the preservation of forest assets and the reduction of anthropogenic impacts on these slowly recovering natural resources. The reflection of forest resources in accounting should be implemented on the basis of the rules defined in the P(S BU 30 called «Biological Assets» and IAS 41 called «Agriculture». In addition, we consider that while reflecting of forest resources in accounting it’s necessary to take into account the life cycle of the tree stand which consists of several stages where each one should be taken into account in the recognition of expenses on their reproduction. For the formation of analytical cuts of the costs of care for the forest resources and their protection is proposed to open the following 3 sub-accounts to the account 155 called «Expenses on the formation of forest resources»: the first is «Expenses on the landing of forest cultures», the second is «Expenses on care for forest resources» and the third one is «Expenses on the protection of forest resources». Sustainable forest management involves the reproduction of forest resources. One of the main criteria for evaluating the effectiveness of forest management

    2006-06-01

    Full Text Available Systems devised for managing tropical forests sustainably have yet to prove successful. In many instances, they have fallen short of initial prospects, but the reasons for these shortfalls are often not apparent. Here, we explore factors that can shape the likelihood of success, collectively referred to as background conditions, which are not always adequately considered prior to selecting a suitable management system. We examine the ability of one background condition, geologic terrane, to explain crude spatial variation in a number of trailing indicators of varying forest land use. Forest areas on Precambrian and Phanerozoic terranes show significant differences in production of fossil hydrocarbons, gold, and tropical roundwood, among other indicators, even after considering regional effects. Background conditions are considered to be factors capable of quantifying spatial variation in the likelihood of achieving management success given predefined benchmarks of sustainability. A number of avenues for further exploring and discriminating spatial variation of background conditions are discussed.

    Full Text Available The concept of sustainable development assigns all the social and economic development methods and forms, whose fundament is firstly represented by the insurance of a balance between these socialeconomic systems and the elements of the natural capital. The most known definition of sustainable development is surely the one of the World Commission on Environment and Development (WCED in the “Our common future” report, also known as the Brundtland Report: “sustainable development is the development that aims at satisfying the present need without compromising future generations‟ possibility to satisfy their own needs”. Sustainable development also aims at and tries to establish a theoretical frame in order to make decisions in all situations that include a human/environment report, whether it is about the environment, the economic or the social environment. Though sustainable development has initially been regarded as a solution to the ecological crisis determined by the huge industrial exploitation of resources and the continuous soil degradation of the environment and it has sought to preserve the quality of the environment, nowadays the concept has been extended to the living quality in its intricacy, involving the economic and social issue. Nowadays, the concern of sustainable development also represents a concern for right and country equality, not only for generations. Within the process, several international conventions have been adopted, which establish precise country requirements and strict implementation terms regarding climate changing, biodiversity preservation, protection of the forest fund and of the wet areas, access to environment quality information and others, that outline an international judicial space for the implementation of the sustainable development concepts.

    Full Text Available BACKGROUND: Sustainable forest management (SFM, which has been recently introduced to tropical natural production forests, is beneficial in maintaining timber resources, but information about the co-benefits for biodiversity conservation and carbon sequestration is currently lacking. METHODOLOGY/PRINCIPAL FINDINGS: We estimated the diversity of medium to large-bodied forest-dwelling vertebrates using a heat-sensor camera trapping system and the amount of above-ground, fine-roots, and soil organic carbon by a combination of ground surveys and aerial-imagery interpretations. This research was undertaken both in SFM applied as well as conventionally logged production forests in Sabah, Malaysian Borneo. Our carbon estimation revealed that the application of SFM resulted in a net gain of 54 Mg C ha(-1 on a landscape scale. Overall vertebrate diversity was greater in the SFM applied forest than in the conventionally logged forest. Specifically, several vertebrate species (6 out of recorded 36 species showed higher frequency in the SFM applied forest than in the conventionally logged forest. CONCLUSIONS/SIGNIFICANCE: The application of SFM to degraded natural production forests could result in greater diversity and abundance of vertebrate species as well as increasing carbon storage in the tropical rain forest ecosystems.

    Full Text Available Urban forestry is increasingly used as a tool for climate change mitigation and for providing environmental services to inhabitants of urban areas. However, tree species used in urban forestry are usually different from the ones used in commercial forestry. As a consequence, available data on growth and yield under alternative management scenarios are usually scarce. As forest models can be used to explore potential forest futures, they are of special interest as decision-support tools in urban forestry. In this research, we used the FORECAST ecosystem-level forest model to define the management prescriptions for Metasequoia glyptostroboides plantations in Shanghai that reach the highest net primary productivity (NPP. In a first step, a battery of different stand densities (from 500 to 4000 stems ha−1 was used to identify those with the highest NPP at stand level. Then, different thinning regimes (with intensities ranging from 15% to 40% of trees removed and applied at stand age 5 to 20 years were simulated on those initial densities with the highest NPP (3000 and 4000 stems ha−1. Planting 4000 stems ha−1 and not applying thinning achieved the highest annual NPP (14.39 ± 3.92 Mg ha−1 yr−1 during the first rotation, but it was not significantly different from the NPP achieved with the same initial density but thinning 40% of trees at year 10. NPP was estimated to decrease with consecutive rotations, and for the second rotation thinning was needed to significantly increase NPP (10.11 ± 2.59 Mg ha−1 yr−1 with 4000 stems ha−1 and 25% thinning at year 10 above non-thinning management. For the third rotation, the highest NPP was reached with initial density 3000 stems ha−1 and 25% thinning at year 10. Nitrogen flows were also estimated to decrease with consecutive rotations. These results indicate the potential of managing M. glyptostroboides urban plantations to reach their maximum productivity potential, but also that additional

    Forested watersheds, an important provider of ecosystems services related to water supply, can have their structure, function, and resulting streamflow substantially altered by land use and land cover. Using a retrospective analysis and synthesis of long-term climate and streamfiow data (75 years) from six watersheds differing in management histories we explored whether streamflow responded differently to variation in annual temperature and extreme precipitation than unmanaged watersheds. We show significant increases in temperature and the frequency of extreme wet and dry years since the 1980s. Response models explained almost all streamflow variability (adjusted R2 > 0.99). In all cases, changing land use altered streamflow. Observed watershed responses differed significantly in wet and dry extreme years in all but a stand managed as a coppice forest. Converting deciduous stands to pine altered the streamflow response to extreme annual precipitation the most; the apparent frequency of observed extreme wet years decreased on average by sevenfold. This increased soil water storage may reduce flood risk in wet years, but create conditions that could exacerbate drought. Forest management can potentially mitigate extreme annual precipitation associated with climate change; however, offsetting effects suggest the need for spatially explicit analyses of risk and vulnerability.

The fact the strategic in implementing the REDD+ and carbon trading in MU level is still lack of pilot project and methodology. Therefore, some scenarios must be developed and tested to find out the best potential of carbon credit in MU level. The objectives of the research were: to calculate carbon credit in some SFM scenarios, to analyze of carbon trading project feasibility, and to determine carbon stock recovery period of logged over area (LOA. The result revealed that carbon stock and carbon credit of LOA was affected by timber cutting intensity.  The 6th scenario with lowest annual allowable cutting (AAC obtained greater carbon credit and profit coming from timber harvesting income and carbon trading. In other hand, this scenario has shortest duration of carbon stock recovery period (27 years and shorter than its cutting cycle.  In this case, the MU has to recalculate and to decrease its AAC to have highest benefits from carbon trading in the same cutting cycle period.  It will provide double benefits from carbon trading, those are contribution in achieving the SFM purposes (production, ecology, social and climate change mitigation.Keywords: sustainable forest management, AAC, carbon stocks, recovery period, carbon trading

  2. Forest Productivity and Diversity: Using Ecological Theory and Landscape Models to Guide Sustainable Forest Management

    Energy Technology Data Exchange (ETDEWEB)

    Huston, M.A.

    1998-11-01

    Sustainable forest management requires maintaining or increasing ecosystem productivity, while preserving or restoring natural levels of biodiversity. Application of general concepts from ecological theory, along with use of mechanistic, landscape-based computer models, can contribute to the successful achievement of both of these objectives. Ecological theories based on the energetics and dynamics of populations can be used to predict the general distribution of individual species, the diversity of different types of species, ecosystem process rates and pool sizes, and patterns of spatial and temporal heterogeneity over a broad range of environmental conditions. This approach requires subdivision of total biodiversity into functional types of organisms, primarily because different types of organisms respond very differently to the spatial and temporal variation of environmental conditions on landscapes. The diversity of species of the same functional type (particularly among plants) tends to be highest at relatively low levels of net primary productivity, while the total number of different functional types (particularly among animals) tends to be highest at high levels of productivity (e.g., site index or potential net primary productivity). In general, the diversity of animals at higher trophic levels (e.g., predators) reaches its maximum at much higher levels of productivity than the diversity of lower trophic levels (e.g., plants). This means that a single environment cannot support high diversity of all types of organisms. Within the framework of the general patterns described above, the distributions, population dynamics, and diversity of organisms in specific regions can be predicted more precisely using a combination of computer simulation models and GIS data based on satellite information and ground surveys. Biophysical models that use information on soil properties, climate, and hydrology have been developed to predict how the abundance and spatial

    , tree mortality has been observed also in stands on favourable soils (rusty brown forest soil, brown earth, lessivated brown forest soil) because these soil sites can only mitigate the damage of extremes. Consequently, there is ongoing change of site conditions that are important for the sustainable forest management planning. Therefore it is an urgent need to rethink regulations considering the changing climate and soil conditions in order to decide about sustainable tree species preference and to maintain forest cover.

    Impacts from human activities at varying scales and intensities have a profound influence on forest carbon dynamics in addition to interactions with climate. As such, forest carbon stocks and fluxes are among the least well-defined elements of the global carbon cycle, and great uncertainty remains in predicting the effect of climate change on forest dynamics. In some cases, these management-climate interactions are well known, but often represent a fundamental gap in our understanding of ecosystem responses and are likely to be important in improving modeling of climate change, and in valuing forest carbon. To improve understanding of human induced forest management-climate interactions, a network of permanent study plots has been established in five sites around the world - in the US, UK, Brazil, India and China. The sites are near larger global monitoring (Smithsonian CTFS) plots to facilitate comparisons. At each site, a series of 1-ha plots have been placed in forest stands with differing management regimes and histories. Utilizing citizen scientists from HSBC bank, all trees >5 cm dbh are tagged, mapped, identified to species, and diameter is recorded within each plot. A subset of trees have dendrometer bands attached, to record seasonal growth. Dead wood and litterfall samples are taken, and microclimate is recorded with automatic sensors. Serial measurements will allow correlation of forest dynamics with weather. Although the studies are at an early stage current results indicate above-ground biomass estimates are 102-288 Mg ha-1 for intermediate and mature Liriodendron tulipifera-dominated stands in the US, respectively. In India, mature semi-natural evergreen forests biomass estimates are 192-235 Mg ha-1 while plantation and semi-natural core forests in the UK are estimated at 211-292 Mg ha-1. Successional Atlantic forests in Brazil are estimated to contain 192-235 Mg ha-1. In the US, initial results have demonstrated dramatic differences in microclimate

    Forest certification is a mechanism involving the regulation of trade of forest products in order to protect forest resources and improve forest management. Although China had a late start in adopting this process, the country has made good progress in recent years. As of July 31, 2009, 17 forest management enterprises and more than one million hectares of forests in China have been certified by the Forest Stewardship Council (FSC). Several major factors affect forest certification in China. The first set is institutional in nature. Forest management in China is based on centralized national plans and therefore lacks flexibility. A second factor is public awareness. The importance and value of forest certification are not widely understood and thus consumers do not make informed choices regarding certified forest products. The third major factor is the cost of certification. Together these factors have constrained the development of China's forest certification efforts. However, the process does have great potential. According to preliminary calculations, if 50% of China's commercial forests were certified, the economic cost of forest certification would range from US0.66-86.63 million while the economic benefits for the forestry business sector could exceed US150 million. With continuing progress in forest management practices and the development of international trade in forest products, it becomes important to improve the forest certification process in China. This can be achieved by improving the forest management system, constructing and perfecting market access mechanisms for certificated forest products, and increasing public awareness of environmental protection, forest certification, and their interrelationship.

  8. SUSTAINABLE MANAGEMENT OF CAMEROON FORESTS RESOURCES: PROVIDING TIMBER WASTE TO THE POOR POPULATIONS AS ALTERNATIVE SOURCE OF ENERGY

    Directory of Open Access Journals (Sweden)

    Serge Benjamin Noumo Foko

    2014-01-01

    Full Text Available Cameroon is covered by about 20 million hectares of forests. Timber exploitation is the second source of external income after petroleum. Besides, Cameroon’s forest has several other functions. Yet the threat to the very existence and survival of this forest is rapidly increasing due to overexploitation by logging companies and for firewood. Despite its usefulness, a substantial volume of the wood felled by timber exploiters is abandoned as waste to rot. This waste can be used as firewood by households even for building and making of furniture by small-scale users like carpenters if they had access to it. This paper encourages the use of timber waste as an alternative to kerosene, which has become very expensive and unaffordable due to the general rise in the price of petroleum products in recent years. The overexploitation of forests can therefore be limited by putting the waste timber into use. It will go along to reduce freshly cut wood which is usually cut illegally and uncontrollably and which is a major source of depletion of forest resources. This project, once achieved will forever last because it will always generate revenue to the groups involve in the collection and the distribution of forest waste which will make money from sales even if they were to sell cheaper since the major cost is transportation and the waste wood is also cheap to obtain from the logging companies or even costless since they have less interest in it.

    Since the United Nations Conference on Environment and Development (UNCED) [1992, Agenda 21: programme of action for sustainable development. United Nations Conference on Environment and Development (UNCED), 3-14 June 1992. Rio de Janeiro, Brazil, 294pp.], the management of information has become central to the management of forest resources. In the cases of North America and Europe, similar issues have been challenging policy makers as they determine the information suitable for monitoring progress towards sustainable forest management (SFM). Using an 'online' survey, this research explored multiple stakeholder perspectives on monitoring and information reporting for SFM in different jurisdictions. The research was based on the premise that an analysis of the variation in stakeholder observations across a range of SFM 'issue areas' could provide valuable insight into the perceived need for SFM-related monitoring and information reporting in the regions of Europe, Canada and the USA. Despite the traditional limitations associated with exploratory survey research, the results indicate a demand for more information on SFM-related issues. The results also highlight the degree to which the perceptions of a sample of stakeholders can differ between Europe, USA and Canada. While these results cannot be generalized beyond the present study, they do suggest that further studies are needed to understand stakeholder perspectives on forestry-related monitoring and information reporting in different jurisdictions.

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available External actor interventions in community forest management (CFM attempt to support communities with developing forest institutions and/or improving their livelihoods portfolio. Common pool resource (CPR scholars argue that forest institutions are required to prevent overharvesting of the forest resource stock (appropriation dilemma, and to encourage investment in its maintenance (provision dilemma. The sustainable livelihoods approach (SLA has been widely used to analyse the influence of interventions on rural livelihoods portfolios. As interventions in CFM span the academic divide between CPR and SLA literatures, analysis of such interventions through either a CPR or SLA lens risks overlooking intervention activities, significant outcomes of the intervention, and the interplay between these outcomes. We propose here an analytical framework which combines CPR and SLA insights and ascertain its applicability by analysing interventions in a forest dependent community in Andhra Pradesh, India. We developed multiple indicators to measure the community’s ability to deal with appropriation and provision dilemmas, and their livelihoods portfolio. Using data from forest plots, household questionnaires, focus group meetings and interviews, we analysed the intervention approaches, activities and outcomes. Our results show that a community’s ability to deal with appropriation and provision dilemmas both affects, and is affected by its livelihoods portfolio. These intricate and dynamic interplays strongly influence the direct and indirect outcomes of intervention activities. Incorporating the synergy between the CPR and SLA perspectives in our analytical framework led us to a much more nuanced understanding of intervention approaches, activities and outcomes than would have otherwise been gained from a single perspective framework.

    Globally, deforestation continues, and although protected areas effectively protect forests, the majority of forests are not in protected areas. Thus, how effective are different management regimes to avoid deforestation in non-protected forests? We sought to assess the effectiveness of different national forest-management regimes to safeguard forests outside protected areas. We compared 2000-2014 deforestation rates across the temperate forests of 5 countries in the Himalaya (Bhutan, Nepal, China, India, and Myanmar) of which 13% are protected. We reviewed the literature to characterize forest management regimes in each country and conducted a quasi-experimental analysis to measure differences in deforestation of unprotected forests among countries and states in India. Countries varied in both overarching forest-management goals and specific tenure arrangements and policies for unprotected forests, from policies emphasizing economic development to those focused on forest conservation. Deforestation rates differed up to 1.4% between countries, even after accounting for local determinants of deforestation, such as human population density, market access, and topography. The highest deforestation rates were associated with forest policies aimed at maximizing profits and unstable tenure regimes. Deforestation in national forest-management regimes that emphasized conservation and community management were relatively low. In India results were consistent with the national-level results. We interpreted our results in the context of the broader literature on decentralized, community-based natural resource management, and our findings emphasize that the type and quality of community-based forestry programs and the degree to which they are oriented toward sustainable use rather than economic development are important for forest protection. Our cross-national results are consistent with results from site- and regional-scale studies that show forest-management regimes that

  18. Sustainability of forest management under changing climatic conditions in the southern United States: adaptation strategies, economic rents and carbon sequestration.

    Science.gov (United States)

    Susaeta, Andres; Carter, Douglas R; Adams, Damian C

    2014-06-15

    The impacts of climate change on profitability and carbon storage in even-aged forest stands of two dominant commercial pine species, loblolly and slash pine, in the southern United States were assessed under alternative assumptions about the impact of climate change on forest productivity and catastrophic disturbance rates. Potential adaptation strategies to reduce losses from disturbance included: 1) alternative planting densities, and 2) planting slash pine instead of loblolly pine. In addition, the amount of sequestered carbon was used to develop an index of economic efficiency for carbon sequestration, which further helps rank the suitability of alternative adaptation strategies. Our results indicate that greater economic rents from forests occur with lower planting densities and the substitution of slash pine for high density loblolly pine. However, less carbon is sequestered by low density loblolly pine compared to slash pine and high density loblolly pine. Both adaptation strategies are economically more effective in terms of carbon sequestration compared to the baseline since they generate more economic revenues per Mg of sequestered carbon.

    2004-04-13

    The objective of this work was to use a simple compartment model of soil carbon (C) and nitrogen (N) dynamics to predict forest recovery on degraded soils and forest sustainability, following recovery, under different regimes of prescribed fire and timber management. This report describes the model and a model-based analysis of the effect of prescribed burning and forest thinning or clearcutting on stand recovery and sustainability at Fort Benning, GA. I developed the model using Stella{reg_sign} Research Software (High Performance Systems, Inc., Hanover, NH) and parameterized the model using data from field studies at Fort Benning, literature sources, and parameter fitting. The model included (1) a tree biomass submodel that predicted aboveground and belowground tree biomass, (2) a litter production submodel that predicted the dynamics of herbaceous aboveground and belowground biomass, (3) a soil C and N submodel that predicted soil C and N stocks (to a 30 cm soil depth) and net soil N mineralization, and (4) an excess N submodel that calculated the difference between predicted plant N demands and soil N supplies. There was a modeled feedback from potential excess N (PEN) to tree growth such that forest growth was limited under conditions of N deficiency. Two experiments were performed for the model-based analysis. In the first experiment, forest recovery from barren soils was predicted for 100 years with or without prescribed burning and with or without timber management by thinning or clearcutting. In the second experiment, simulations began with 100 years of predicted forest growth in the absence of fire or harvesting, and sustainability was predicted for a further 100 years either with or without prescribed burning and with or without forest management. Four performance variables (aboveground tree biomass, soil C stocks, soil N stocks, and PEN) were used to evaluate the predicted effects of timber harvesting and prescribed burning on forest recovery and

    Full Text Available Forests provide a full spectrum of goods and services that contribute to the socio-economic development of forest dependent communities. In tropical countries, the diversity of stakeholders depending on forests with their divergent interests and expectations, make sustainable forest management (SFM difficult to achieve. Although several studies advocate the decentralization of forest management and public participation as important processes for SFM, little has been done to demonstrate how these processes could contribute to forest sustainability and socioeconomic development of forest dependent communities. Moreover, almost no seminal paper has demonstrated how to integrate the ecological, economical and social issues of forest management, which have nevertheless been recognized as essential for sustainable forest management. This study develops an ecosystemic forest management approach based on “Stakeholder-Resource-Usage-Institution” dynamics as an appropriate framework for ensuring forest sustainability and socio-economic development. This approach is supported with lessons drawn on the limitations and pitfalls of the traditional forest management approach in Southeast Cameroon.Les forêts fournissent toute une gamme de biens et de services qui contribuent au développement socio-économique des communautés dépendantes de la forêt.

    Full Text Available Building the adaptive capacity of interlinked social and ecological systems is assumed to improve implementation of sustainable forest management (SFM policies. One mechanism is collaborative learning by continuous evaluation, communication, and transdisciplinary knowledge production. The Model Forest (MF concept, developed in Canada, is intended to encourage all dimensions of sustainable development through collaboration among stakeholders of forest resources in a geographical area. Because the MF approach encompasses both social and ecological systems, it can be seen as a process aimed at improving adaptive capacity to deal with uncertainty and change. We analyzed multi-stakeholder approaches used in four MF initiatives representing social-ecological systems with different governance legacies and economic histories in the northwest of the Russian Federation (Komi MF and Pskov MF and in Sweden (Vilhelmina MF and the Foundation Säfsen Forests in the Bergslagen region. To describe the motivations behind development of the initiative and the governance systems, we used qualitative open-ended interviews and analyzed reports and official documents. The initial driving forces for establishing new local governance arrangements were different in all four cases. All MFs were characterized by multi-level and multi-sector collaboration. However, the distribution of power among stakeholders ranged from clearly top down in the Russian Federation to largely bottom up in Sweden. All MF initiatives shared three main challenges: (a to develop governance arrangements that include representative actors and stakeholders, (b to combine top-down and bottom-up approaches to governance, and (c to coordinate different sectors' modes of landscape governance. We conclude that, in principle, the MF concept is a promising approach to multi-stakeholder collaboration. However, to understand the local and regional dimensions of sustainability, and the level of adaptability

    The demand for forest biomass is increasing and there is large potential for increasing biomass production of northern forest ecosystems by various management strategies involving N fertilization. Increased biomass production also leads to more atmospheric carbon sequestration that potentially can mitigate climate change. N fertilization has been shown to increase biomass production and to decrease soil respiration rates. However, the potential increase in N2O emissions following N addition may counteract the sustainability of such management practices in terms of its impact on the sink/source relationship of greenhouse gases. Here we evaluate the effect of various N addition intensities on the soil-atmosphere exchange of CO2 and N2O in a long-term field experiment in a boreal Scots pine (Pinus sylvestris) forest stand. The stand was planted in 1953 and the experiment was established in 1974 with annual N addition at four levels (N0, N1, N2, and N3 receiving 0, 35, 70, and 110 kg N ha-1 year-1, respectively) organized in a randomized block design (n=3) in plots of 30x30m. The high (N3) and intermediate (N2) N addition levels were terminated in 1990 and 2006, respectively, and offered an opportunity to investigate recovery of greenhouse gas exchange following high N loading. Soil-atmosphere exchange of GHGs were estimated weekly during 2010-2011 based on static chamber measurements during the snow free period and snow concentration gradients during winter. In the ongoing treatment (N1) the annual N2O emissions were 25 mg N2O m-2 yr-1, as compared to 6 mg N2O m-2 yr-1 in the control plots, representing a ca 4-fold significant increase due to N-addition. The N2O-N loss from the treatment corresponded to ca 0.5% of the annually added N (35 kg N ha-1). In the N2 treatment (terminated in 2006) annual N2O emissions were 15 mg N2O m-2 yr-1, while in the N3 treatment N2O emissions were the same as in the control plots with no N-additions. Thus the system has capacity to

    Full Text Available The first objective of this paper was to provide an inventory of developments of certification schemes for sustainable biomass production, following recent EU legislation (both formalized and under development. One main pillar is the EU Timber Regulation for legal harvesting; a second one is the EU’s 2010 recommendations for sustainable woody biomass sourcing for energy; the third one is the EU Waste Directive. The second objective was to benchmark the coverage of this (draft legislation, when wood product certificates for sustainable forest management (SFM are used as proof of the related legislative requirements. We studied North America, as it is a major biomass supplier to the EU-28. Together with existing forest legislation in the US and Canada, SFM certificates are actively used to cover the EU’s (draft legislation. However, North American forests are only partially certified with fibers coming from certified forests; these are referred to as forest management (FM fibers. Other certified fibers should come from complementary risk assessments downstream in the supply chain (risk based fibers. Our benchmark concludes that: (a FM fiber certification by the Forest Stewardship Council (FSC and the Program for the Endorsement of Forest Certification (PEFC international standards show the highest level of coverage with EU’s (draft legislation; (b There is insufficient coverage for risk based fibers by FSC Controlled Wood (FSC-CW, PEFC Due Diligence (PEFC-DD, or SFI-fiber sourcing (SFI-FS. Other weaknesses identified for elaboration are: (c Alignment in definitions are needed, such as for primary forest, high carbon stock, and wood waste (cascading; (d Imperfect mass balance (fiber check downstream needs to be solved, as non-certified fiber flows are inadequately monitored; (e Add-on of a GHG calculation tool is needed, as GHG life cycle reporting is not covered by any of the SFM frameworks.

  7. Assessment of Selected Parameters of the Automatic Scarification Device as an Example of a Device for Sustainable Forest Management

    Full Text Available Due to technological progress in forestry, seedlings with covered root systems—especially those grown in container nurseries—have become increasingly important in forest nursery production. One the trees that is most commonly grown this way is the common oak (Quercus robur L.. For an acorn to be sown in a container, it is necessary to remove its upper part during mechanical scarification, and evaluate its sowing suitability. At present, this is mainly done manually and by visual assessment. The low effectiveness of this method of acorn preparation has encouraged a search for unconventional solutions. One of them is the use of an automated device that consists of a computer vision-based module. For economic reasons related to the cost of growing seedlings in container nurseries, it is beneficial to minimize the contribution of unhealthy seeds. The maximum accuracy, which is understood as the number of correct seed diagnoses relative to the total number of seeds being assessed, was adopted as a criterion for choosing a separation threshold. According to the method proposed, the intensity and red components of the images of scarified acorns facilitated the best results in terms of the materials examined during the experiment. On average, a 10% inaccuracy of separation was observed. A secondary outcome of the presented research is an evaluation of the ergonomic parameters of the user interface that is attached to the unit controlling the device when it is running in its autonomous operation mode.

  9. Evolution of Forest Systems: the Role of Biogeochemical Cycles in Determining Sustainable Forestry Practices

    Directory of Open Access Journals (Sweden)

    Werner T. Flueck

    2009-12-01

    Full Text Available The exploitation of natural resources such as forests leads to sustainable forest management (SFM. The key question is how to define and parametrize "sustainable use." Promoting forest use that conserves spatial characteristics of forest landscapes and the structure and composition of forest stands was proposed as a way of maintaining elements of biodiversity such as species richness and genetic variation. However, to establish the parameter space for sustainable forest use, it is essential to consider the nutrient requirements of forest systems, that is, plants and animals, the need for fertilizer application, and the effects on biogeochemical cycles, a cornerstone of biological evolution and, thus, biodiversity. The use of forest products is inevitably tied to exporting biomass from those ecosystems because products are used elsewhere, thus changing natural practically steady-state ecosystems to open ones. Continued biomass export results in soil acidification and nutrient removal. Among macronutrients, phosphorus takes a key position, but several others have been shown to be depleted in managed-forest systems. Micronutrients are more crucial for forest-dwelling animals, particularly those nutrients that are only essential to animals. Depletion of their reserves, selenium for instance, through biomass export will not affect plants, and initial subclinical effects on animals are difficult to detect. The generalized effect may be reflected in changing rates of recruitment or disease resistance, and thus ecosystem processes. Forest products and their export reduces soil-nutrient reserves, and slash burning and water runoff further add to cumulative losses of several minerals. Such impacts from forest products need to be addressed, particularly for mammals and their unique needs for several microelements. Biogeochemical cycles disturbed by exporting forest products will affect plants and animals and, therefore, ecosystems and their processes, and

    Through centuries of farming practices the farmers and pastoralists in Ethiopia were managing their land resources pertaining to the needs of prevalent populations. With an increasing population and growing demands, more land was put under cultivation. Subsequently forest areas were cleared, encroaching agriculture into steep slopes and areas that were not suitable for agricultural activities. Land degradation and particularly soil erosion by water not only reduced the productivity of the land but also aggravated the effects of drought, such as famine and migration. Obvious signs of degradation in the highlands of Ethiopia are wide gullies swallowing fertile lands and rock outcrops making farming a risky business. But also less visible sheet erosion processes result in a tremendous loss of fertile topsoil, particularly on cropland. Efforts have been made by the farming communities to mitigate land degradation by developing local practices of conserving soil and water. With keen interest and openness one can observe such indigenous practices in all corners of Ethiopia. Notwithstanding these practices, there were also efforts to introduce other soil and water conservation interventions to control erosion and retain the eroded soils. Since the early 1980s numerous campaigns were carried out to build terraces in farmlands and sloping areas. Major emphasis was given to structural technologies rather than on vegetative measures. Currently the landscape of the northern highlands is dotted with millions of hectares of terraced fields and in some places with planned watershed management interventions including exclosures. Apparently these interventions were introduced without prior investigating the detailed problems and conservation needs of the local population. Intensive research is undertaken on the processes of degradation, the impact of the different intervention measures and the role of communities in sustainably managing their land. This paper attempts to review the

    Full Text Available Normal 0 14 false false false IT JA X-NONE The European Community has long recognized the need to further promote renewable energy. Under the overall objective to support and enhance sustainable management, the promotion of the use of forest biomass could help to mitigate climate change by substituting fossil fuel, increasing carbon stock in wood products and improve energy self-sufficiency enhancing security of supply and providing job opportunities in rural areas. To what extent Italian forests can satisfy an increased wood demand, without compromising the others Ecosystem Services (ESs remains an open question. Our aim was to assess the potential supply of woody biomass from the network of protected areas in Italy considering the felling constraints. We estimated the theoretical annual potential increment from forest inventory data performing a correlation with the Corine Land Cover 2006 at the IV level with a 1:100,000 resolution elaborated in a GIS (Geographic Information System environment. The average annual potential increment at national level available for felling was 4.4 m3ha-1. Within the network of protected areas (EUAP and Natura 2000, the average annual increment, available to felling, was 0.98 m3ha-1, respectively, 0.81 m3ha-1 from coppice and 1.14 m3ha-1 from non-coppice forests. Based on data obtained from this study, the availability of wood materials could be increased of almost 20 % at national level by pursuing an active management within the network of protected areas. In Italy, the actual level of resource utilization is rather low; increasing felling together with the implementation of an active management within protected areas could allow satisfying, theoretically, the Italian wood consumption. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabella normale"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0

  16. A Toolkit Modeling Approach for Sustainable Forest Management Planning: Achieving Balance between Science and Local Needs

    Brian R. Sturtevant

    2007-12-01

    Full Text Available To assist forest managers in balancing an increasing diversity of resource objectives, we developed a toolkit modeling approach for sustainable forest management (SFM. The approach inserts a meta-modeling strategy into a collaborative modeling framework grounded in adaptive management philosophy that facilitates participation among stakeholders, decision makers, and local domain experts in the meta-model building process. The modeling team works iteratively with each of these groups to define essential questions, identify data resources, and then determine whether available tools can be applied or adapted, or whether new tools can be rapidly created to fit the need. The desired goal of the process is a linked series of domain-specific models (tools that balances generalized "top-down" models (i.e., scientific models developed without input from the local system with case-specific customized "bottom-up" models that are driven primarily by local needs. Information flow between models is organized according to vertical (i.e., between scale and horizontal (i.e., within scale dimensions. We illustrate our approach within a 2.1 million hectare forest planning district in central Labrador, a forested landscape where social and ecological values receive a higher priority than economic values. However, the focus of this paper is on the process of how SFM modeling tools and concepts can be rapidly assembled and applied in new locations, balancing efficient transfer of science with adaptation to local needs. We use the Labrador case study to illustrate strengths and challenges uniquely associated with a meta-modeling approach to integrated modeling as it fits within the broader collaborative modeling framework. Principle advantages of the approach include the scientific rigor introduced by peer-reviewed models, combined with the adaptability of meta-modeling. A key challenge is the limited transparency of scientific models to different participatory groups

    In this article, we introduce China's major forest types and discuss the historical development of forest management in China, including actions taken over the last decade toward achieving SMF. Major challenges are identified, and a strategy for SFM implementation in China is presented. China's forests consist of a wide variety of types with distinctive distributional patterns shaped by complex topography and multiple climate regimes. How to manage this wide array of forest resources has challenged forest managers and policy-makers since the founding of the country. Excessive exploitation of China's forest resources from the 1950s to the late 1990s contributed to environmental problems and calamities, such as floods, soil erosion, and desertification. At the start of the new millennium, the Chinese government decided to shift its emphasis from timber production towards the achievement of sustainable forest management (SFM). With a series of endeavors such as the implementation of the "Six Key Forestry Projects" and the reform of forest tenure policies, and the adoption of a classification system for China's forests, a beginning has been made at reversing the trend of environmental degradation that occurred throughout the latter half of the last century. At the same time, huge challenges remain to be tackled for the development of forestry in China.

This paper uses Gansu Baishuijiang National Natural Reserve in China as a case study for livelihood improvements under CBCM projects. We demonstrate change from 2006 to 2010 in five classes of livelihood capital (social, human, natural, physical and financial capitals), illustrating the effectiveness of CBCM projects. Specifically, there are increases in mean family income and improvements in forest conservation. However, some problems in the design and implementation of CBCM projects remain, including the complicated social and political relationship between government and community, social exclusion and uneven application of benefits within communities, and the lack of integration of indigenous cultures and traditional beliefs. Attention for special groups in community and improving the design of CBCM Projects. Study shows that under the cooperation of government, CBCM projects and local community residents, the harmonious development of sustainable livelihood improvement and forest resources conservation will be an important trend in the future.

    Forests are complex systems, and it is necessary to include this characteristic in every forest definition, in order to consider the restriction that this imposes in terms of prediction and control. This lost of predictability and controllability should be incorporated in every Environmental Impact Assessment or management program. We present two case-studies located in Mexico and one in the US to illustrate three relevant indicators of complexity. First, we introduce an informational framework to measure the Zoquiapan forest systemic complexity. Then, we analyze complexity changes among different types of forest and management systems, related with spatial distributions, using data from a floristic study in the Montes Azules National Park. Finally, we analyze time series of $CO_{2}$ fluctuations taken from AMERIFLUX data bases. Our results show firstly that it is possible to measure the systemic complexity of different forests, characteized by a criticality state (1/f noise) which has been proposed as a fing...

    Full Text Available Sustainability and sustainable behaviour is of crucial importance in the management of Fennoscandian forests and forest-related industries. This paper reviews a number of voluntary instruments, which aim at promoting or assessing sustainability impacts at different levels. The multitude of available instruments brings confusion in practice, where companies, consumers and investors meet legal and different voluntary regulatory and non-regulatory instruments. The practical suitability and covered sustainability dimension for each instrument is reviewed with an analysis of strengths, weaknesses, actors and purposes for assessing different aspects of sustainability. Each of them is compared against the other in an overview about which sustainability dimensions they cover (workplace, human rights, community, market place, environment, economy. Results highlight covered, overlapping and missing aspects for each approach and how they can support or reinforce each other. Special attention is given to current approaches in impact assessment, particularly on their areas of application (companies, NGOs, products, operations, production practices, etc., and recommendations for supplementing it with sustainability impact assessment.

    Full Text Available Mountain ecosystems are highly sensitive to global change. In fact, the continued capacity of mountain regions to provide goods and services to society is threatened by the impact of environmental changes on ecosystems. Although mapping ecosystem services values is known to support sustainable resource management, the integration of spatially explicit local expert knowledge on ecosystem dynamics and social responses to global changes has not yet been integrated in the modeling process. This contribution demonstrates the importance of integrating local knowledge into the spatially explicit valuation of ecosystem services. Knowledge acquired by expert surveys flows into a GIS-based Bayesian Network for valuing forest ecosystem services under a land-use and a climate change scenario in a case study in the Swiss Alps. Results show that including expert knowledge in ecosystem services mapping not only reduces uncertainties considerably, but also has an important effect on the ecosystem services values. Particularly the iterative process between integrating expert knowledge into the modeling process and mapping ecosystem services guarantees a continuous improvement of ecosystem services values maps while opening a new way for mutual learning between scientists and stakeholders which might support adaptive resource management.

    2017-12-01

    Full Text Available The basic principle of silviculture is the rational use of natural regeneration. The acceleration and equalisation of seed germination and an increase of the field seed germination ability are affected by seed scarification, which results in the destruction or weakening of the seed cover. Acorn scarification is performed manually, in the standing position, most often in adapted work stations, whose geometry is adjusted by the staff to their own anthropometric dimensions. An added value of acorn scarification consists in the ability to visually assess the health status of the cotyledons visible on the cross-section, making it possible to infer the potential use of a seed for sowing. However, due to the scope and duration of the activities involved, manual scarification is a process that is monotonous and physically as well as psychologically tiring for its performer. Automating of this process allows for effective replacement of human labour. The results obtained from the use of the vision system designed to determine the length and orientation of acorns may be considered satisfactory. The implementation of the seed orientation detection algorithm using the Harris detector was 90% accurate. Studies and analyses have shown that the process of acorn scarification has a positive effect on the later improvement of uniformity and acceleration of seedling emergence. In the case of seeds subjected to scarification, 83% of the acorns germinated within 4 to 6 weeks after sowing.

The United Nations' 17 sustainable development goals (SDGs and their 169 targets are ambitious, broadly encompassing, and indivisible. They are intended to guide nations and communities toward attaining healthy and peaceful livelihoods free of poverty and hunger. Collectively the goals envision sound and safe environments, where global threats like climate change are successfully combated through both mitigation and adaptation. Agenda 2030 envisages sustainable production patterns with inclusive, effective economies and institutions. It is of specific relevance to mountain communities, where the population is predominantly rural and half of the rural inhabitants experience food insecurity and are often highly dependent on forest resources. Mountain forests also contribute to human welfare well beyond the local community: through functions such as climate and hydrological services provided at regional and global scales, and harvested commodities traded at multiple economic scales. In this introductory essay we argue that sustainable forest management in mountain areas disproportionately contributes to achieving the SDGs. We discuss (1 the potential of mountain forests to help achieve SDGs in mountainous regions and beyond, (2 the potential of the SDGs to help solve severe socioeconomic and ecological problems in forested mountain areas, and (3 challenges and opportunities associated with implementing the SDGs. We base our argumentation also on the 8 papers presented in this Focus Issue of Mountain Research and Development. Together, they establish a clear connection between sustainable use and protection of mountain forests and vital ecosystem services upon which many regions depend. We

    Full Text Available For a sustainable forest management, beside the choice of the right species in artificial regeneration, the right provenances present their own importance. The existing legal regulation on forest reproductive material moving in trade can only provide an absolute proof of identity, at an unproportionally intense level of controlling. Techniques based on the analysis of DNA markers are a powerful tool for the genetic traceability of forest reproductive material, but on a European level, the traceability systems are yet missing, excepting the two certification systems implemented in Germany (ZüF and FfV. The reference samples collected from individuals in different steps of the forest reproductive material production, and the comparison of their genetic composition, are the principle underlying the German certification systems. The seeds from seed orchards can be identified with highly polymorphic SSR markers, once the the genetic profile of the reference clone is known, without reference samples. For different pourpose, suitable DNA markers are available, and the nuclear microsatellies are the more usefull in individual identification. Different statistical approaches can still be used to assign individual or groups of individuals to a population, but this requires further evaluation for their use in traceability. The control procedures are under development at European level. Their implementation are necessary also in Romania, as connecting to the present scientifical trends, and also related to its position as seeds provided for other European countries.

  15. Experts’ Perceptions of the Effects of Forest Biomass Harvesting on Sustainability in the Alpine Region

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Background and Purpose: In the EU political agenda, the use of forest biomass for energy has grown rapidly and significantly, in order to mitigate carbon dioxide emissions and reduce the energy dependence on fossil fuels of European member countries. The target of the EU climate and energy package is to raise the share of renewable energy consumption produced from renewable resources to 20% in 2020 (Directive 2009/28/EC. With regards to biomass energy, the supply of forest wood biomass is expected to rise by 45% (reference period: 2006-2020, in response to increasing demand for renewable sources. The increase of forest biomass supply could have both positive and negative effects on several forest ecosystem services (ESs and local development. These effects should be assessed in a proper manner and taken into account when formulating management strategies. The aim of the paper is to assess the environmental, economic and social sustainability of forest biomass harvesting for energy, using the Figure of Merit (FoM approach. Materials and Methods: Sustainability was assessed through a set of four indicators: two focused on experts’ opinions regarding the effects of forest biomass harvesting and the other two focused on the cost-benefit analysis (potential energy obtained and costs for wood chips. The research was developed through four case studies located in the Alpine Region. A semi-structured questionnaire was administered face-to-face to 32 selected experts. The perceived effects of forest biomass harvesting for energy on ESs and local development were evaluated by experts using a 5-point Likert scale (from “quite negative effect” to “quite positive effect”. Results: All experts agree that forest biomass harvesting has a positive effect on forest products provision and local economic development (employment of local workforce, local entrepreneurship and market diversification, while the effects on other ESs are controversial (e

  18. Historical Patterns of Natural Forest Management in Costa Rica: The Good, the Bad and the Ugly

    Directory of Open Access Journals (Sweden)

    J. Pablo Arroyo-Mora

    2014-07-01

    Full Text Available We present an in-depth analysis of natural forest management practices in Costa Rica based on a new historical forestry GIS database encompassing five conservation regions in the country where selective logging has been prevalent for the last 18 years. Natural forest management refers to the selective logging practices for the production of timber in natural forest ecosystems. The study considers natural forest management plans developed following a standardized format, based on Forestry Law 7575, established in 1996. Our results show a positive aspect of forest management where a large percentage of the managed forest is still standing, contrary to other tropical countries where selective logging promotes land use change. The negative finding is that managed forest areas occur in the last remaining forest fragments outside of protected areas, which challenges the continuity of selective logging in the near and mid future due to the potential impoverishment of the isolated forest stands. The most negative aspect is the recent establishment, by law, of a very short return logging cycle (10–15 years—minimum cutting cycle as it contradicts ecological studies showing that tropical forests require over 60 years for the forest structure and composition to return to a state similar to pre-logging states. Our results should inform decision makers and managers in conservation areas to review current policies and establish new benchmarks for sustainable forest management in the country.

  20. Analysis and deliberation as a mechanism to assess changes in preferences for indicators of sustainable forest management: a case study in Puebla, Mexico.

    Rodriguez-Piñeros, Sandra; Lewis, David K

    2013-10-15

    The purpose of this study was to assess changes in forest owners' preferences regarding indicators of sustainable forest management. The analysis and deliberation framework served as a platform upon which to explore these changes in a rural community in Puebla, Mexico. Sixty-two indicators were selected from existing sets to design a five-point Likert survey instrument. The instrument was administered three times: early in the study to capture the forest owners' preferences before intervention (baseline); following an educational meeting in which the participants learned of three alternative forest management plans (analysis); and following a community meeting in which the forest owners deliberated to choose one of the alternatives (deliberation). As forest owners were exposed to knowledge (analysis) and deliberation, their preferences for the indicators changed significantly. An examination of the instrument demonstrated how the indicators increased or decreased in importance. Social and economic indicators tended to be ranked differently following analysis and again following deliberation because of the commitment to pursue a forest management plan that would benefit the community without jeopardizing stakeholder values. The ecological indicators directly associated with forest structure gained relevance following the analysis meeting. The deliberation process elucidated the importance of forest administration and professional help. Forest owners' preferences were reflected by the selection of the management plan that included good science and accommodated community values. The forest owners changed their preferences in response to new knowledge, management objectives, and their commitment to safeguarding the future condition of the forest. Analysis and deliberation is a participatory forum that facilities communication and learning and allows stakeholders to share values; thus, it serves as a mechanism for forest planning.

  2. Is Matang Mangrove Forest in Malaysia sustainably rejuvenating after more than a century of conservation and harvesting management?

    Directory of Open Access Journals (Sweden)

    Arnaud Goessens

    Full Text Available Matang Mangrove Forest Reserve (MMFR in Peninsular Malaysia is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. The present study on silvimetrics assessed the ongoing MMFR forest management, which includes a first thinning after 15 years, a second thinning after 20 years and clear-felling of 30-year old forest blocks, for its efficiency and productivity in comparison to natural mangroves. The estimated tree structural parameters (e.g. density, frequency from three different-aged mangrove blocks of fifteen (MF15, twenty (MF20, and thirty (MF30 years old indicated that Bruguiera and Excoecaria spp. did not constitute a significant proportion of the vegetation (<5%, and hence the results focused majorly on Rhizophora apiculata. The density of R. apiculata at MF15, MF20 and MF30 was 4,331, 2,753 and 1,767 stems ha(-1, respectively. In relation to ongoing practices of the artificial thinnings at MMFR, the present study suggests that the first thinning could be made earlier to limit the loss of exploitable wood due to natural thinning. In fact, the initial density at MF15 was expected to drop down from 6,726 to 1,858 trees ha(-1 before the first thinning. Therefore the trees likely to qualify for natural thinning, though having a smaller stem diameter, should be exploited for domestic/commercial purposes at an earlier stage. The clear-felling block (MF30 with a maximum stem diameter of 30 cm was estimated to yield 372 t ha(-1 of the above-ground biomass and suggests that the mangrove management based on a 30-year rotation is appropriate for the MMFR. Since Matang is the only iconic site that practicing sustainable wood production, it could be an exemplary to other mangrove locations for their improved management.

    Full Text Available This paper presents a comparative study of forest management across four countries in East Africa and Latin America: Kenya, Uganda, Bolivia, and Mexico. It focuses on one question: Do varying proportions of women (low, mixed, high in forest user groups influence their likelihood of adopting forest resource enhancing behavior? We found that higher proportions of females in user groups, and especially user groups dominated by females, perform less well than mixed groups or male dominated ones. We suggest that these differences may be related to three factors: gender biases in technology access and dissemination, a labor constraint faced by women, and a possible limitation to women's sanctioning authority. Mixed female and male groups offer an avenue for exploiting the strengths of women and men, while tempering their individual shortcomings.

    new markets and incentives for sustainable forest management and community-based forest management, and e changes in forest land ownership, including the decentralisation of forest governance and devolution of forest land. We conclude that the changes are generating different effects. Whereas the expansion of external markets is leading to increased deforestation, the decentralisation and democratisation of forest governance and a global preoccupation with the loss of environmental services and livelihood opportunities for local people is creating new incentives for sustainable forest management. The greatest challenge is to find ways to make family-based logging and sawmill operations in settlement areas more sustainable, for instance through innovative company-community partnerships.

    2013-12-01

    We explored different management strategies for a Cembran pine forest close to the timber line with respect to maintenance of the stand structure, the sequestration of carbon in the biomass and the soil, and the economical relevance of timber production. We used the forest growth simulation model Caldis for the implementation of three management intensities (zero managment, thinning every 30 years, thinning every 50 years) under two climate scenarios (IPCC A1B and B1). The soil carbon dynamics were analyzed with the simulation model Yasso07. The ecological evaluation of our simulation data showed that the extensive management with cutting interventions every 50 years allows the maintenance of the ecosystem carbon pool. Zero managment leads to the build-up of the carbon pool because the forest stand is rather unvulnerable to disturbances (bark beetle, storm). The more intensive mangement causes a decline in the ecosystem carbon pool. The economical evaluation showed the marginal relevance of the income generated by timber production. The main challenge is the compensation for the high harvesting costs (long-distance cable logging system). Even at extremely favorable market prices for timber from Cembran pine it is impossible to extract an appropriate amount of timber to justify the temporary instalment of the harvesting system and to maintain a stand density expected for a protection forest. We conclude that timber production is not a feasible object for mountain forests close to the timber line. Even in a warmer climate the productivity situation of forests close to the timberline will not change sufficiently. Therefore it will require public subsidies and personal efforts to maintain the silvicultural intensity at a level that is required for the sustainable maintenance of protection forests.

The correlation coefficient shows although all forest variables did have a significant correlation with the forest classes, stand volume appeared to have the strongest correlation with forest classes. These are 0.64 and 0.59 for four and three strata respectively. The results of supervised classification also show the four strata of heavily degraded forest, moderate disturbance, insignificant disturbance, and dense forest were discriminated more clearly comparing to the forest stratified into three classes. The proof is that overall accuracy of supervised classification was 86% with Kappa of 0.8 for four classes, meanwhile, these are 77% and 0.62 respectively for forest area classified into 3 classes.

    Aim of the study: To review and acknowledge the value of carbon sequestration by forest management in the Mediterranean area. Material and methods: We review the main effects of forest management by comparing the effects of silviculture systems (even-aged vs. uneven-aged stands, coppice systems, agroforestry systems), silvicultural options (thinning, rotation period, species composition), afforestation, harvesting, fire impact or effects of shrub layer on carbon sequestration in the Mediterranean area. Main results: We illustrate as forest management can clearly improve forest carbon sequestration amounts. We conclude that forest management is an effective way to maintain and enhance high carbon sequestration rates in order to cope with climate change and provision of ecosystem services. We also think that although much effort has been put into this topic research, there are still certain gaps that must be dealt with to increase our scientific knowledge and in turn transfer this knowledge to forest practitioners in order to achieve sustainable management aimed at mitigating climate change. Research highlights: It is important to underline the importance of forests in the carbon cycle as this role can be enhanced by forest managers through sustainable forest management. The effects of different management options or disturbances can be critical as regards mitigating climate change. Understanding the effects of forest management is even more important in the Mediterranean area, given that the current high climatic variability together with historical human exploitation and disturbance events make this area more vulnerable to the effects of climate change.

    Sweeping across Bangladesh and India, the Sundarbans forest is the world's largest contiguous mangrove forest. Although the human population density is high at the edge, Sundarbans has not encountered significant areal transformation in the last four decades. However, we argue that forest degradation can occur discontinuously within the forest without alteration of the entire forest area. In this paper, we used MODIS land products to compare the spatiotemporal ecological dynamics of the Bangladesh and Indian part of this mangrove forest between 2000 and 2010. We used the following 5 ecological parameters for our analysis: the Percent Tree Cover (PTC), Enhanced Vegetation Index (EVI), Net Primary Productivity (NPP), Leaf Area Index (LAI), and Evapotranspiration (ET). Our pixel-based time-series trend analysis for each MODIS image stack, using an ordinary least square (OLS) regression method, showed that forest degradation is happening in fragmented parcels within the forest. The degradation rate is comparatively higher in the Bangladesh part than in the Indian part of Sundarbans. Compartments 8, 10, 12, and 15 in the Bangladesh part, in particular, show high degradation, while compartment 48 and the southern edge of 45 show slight increases in PTC or EVI. Forest degradation in the Indian part of the forest is evident in the National Park and Reserve Forest blocks; however, no substantial degradation is evident in the western section. We have identified certain anthropogenic stressors (i.e., oil pollution, shrimp farming) and natural stressors (i.e., increased salinity, cyclones, forest fire) which might be responsible for the observed degradation. We have provided sustainable planning options and policy transformation alternatives for those areas under pressure from these stressors. We anticipate that our analysis of forest degradation will help management agencies, conservators, and policy makers achieve better management of this world's largest mangrove forest for

    We examine five forested landscapes in Africa (Cameroon, Madagascar, and Tanzania) and Asia (Indonesia and Laos) at different stages of landscape change. In all five areas, forest cover (outside of protected areas) continues to decrease despite local people's recognition of the importance of forest products and services. After forest conversion, agroforestry systems and fallows provide multiple functions and valued products, and retain significant biodiversity. But there are indications that such land use is transitory, with gradual simplification and loss of complex agroforests and fallows as land use becomes increasingly individualistic and profit driven. In Indonesia and Tanzania, farmers favor monocultures (rubber and oil palm, and sugarcane, respectively) for their high financial returns, with these systems replacing existing complex agroforests. In the study sites in Madagascar and Laos, investments in agroforests and new crops remain rare, despite government attempts to eradicate swidden systems and their multifunctional fallows. We discuss approaches to assessing local values related to landscape cover and associated goods and services. We highlight discrepancies between individual and collective responses in characterizing land use tendencies, and discuss the effects of accessibility on land management. We conclude that a combination of social, economic, and spatially explicit assessment methods is necessary to inform land use planning. Furthermore, any efforts to modify current trends will require clear incentives, such as through carbon finance. We speculate on the nature of such incentive schemes and the possibility of rewarding the provision of ecosystem services at a landscape scale and in a socially equitable manner.

An inappropriate policy is more important a cause of the forest sustainability than a corrupt behavior. Therefore, fixing this structural mistake needs to be prioritized in combating the forest destruction, for this structural mistake is the real primary cause of the forest destruction in Indonesia. Fixing this structural mistake is much more effective in combating the forest destruction than finding honest bureaucrats. Keywords:     Birokrat, Distortionary, Nondistortionary, Kelestarian, Korup.

    The Sumatran orangutan is currently listed by the IUCN as critically endangered and the Bornean species as endangered. Unless effective conservation measures are enacted quickly, most orangutan populations without adequate protection face a dire future. Two main strategies are being pursued to conserve orangutans: (i) rehabilitation and reintroduction of ex-captive or displaced individuals; and (ii) protection of their forest habitat to abate threats like deforestation and hunting. These strategies are often mirrored in similar programs to save other valued and endangered mega-fauna. Through GIS analysis, collating data from across the literature, and combining this information within a modelling and decision analysis framework, we analysed which strategy or combination of strategies is the most cost-effective at maintaining wild orangutan populations, and under what conditions. We discovered that neither strategy was optimal under all circumstances but was dependent on the relative cost per orangutan, the timescale of management concern, and the rate of deforestation. Reintroduction, which costs twelve times as much per animal as compared to protection of forest, was only a cost-effective strategy at very short timescales. For time scales longer than 10-20 years, forest protection is the more cost-efficient strategy for maintaining wild orangutan populations. Our analyses showed that a third, rarely utilised strategy is intermediate: introducing sustainable logging practices and protection from hunting in timber production forest. Maximum long-term cost-efficiency is achieved by working in conservation forest. However, habitat protection involves addressing complex conservation issues and conflicting needs at the landscape level. We find a potential resolution in that well-managed production forests could achieve intermediate conservation outcomes. This has broad implications for sustaining biodiversity more generally within an economically productive landscape

    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 USD36 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. (author)

  11. Ecological Sustainability of Birds in Boreal Forests

    Gerald Niemi

    1998-12-01

    Full Text Available We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and sustaining these populations affords many benefits to the health of boreal forests. Many issues must be approached with caution, including the lack of knowledge on our ability to mimic natural disturbance regimes with management, our lack of understanding on fragmentation due to logging activity, which is different from permanent conversion to other land uses such as agriculture or residential area, and our lack of knowledge on what controls variability in boreal bird populations or the linkage between bird population fluctuations and productivity. The essential role that birds can provide is to clarify important ecological concerns and variables that not only will help to sustain bird populations, but also will contribute to the long-term health of the boreal forest for all species, including humans.

    Although mangroves dominated by Avicennia germinans and Rhizophora mangle are extending over 6000 ha in the Tanbi Wetland National Park (TWNP) (The Gambia), their importance for local populations (both peri-urban and urban) is not well documented. For the first time, this study evaluates the different mangrove resources in and around Banjul (i.e., timber, non-timber, edible, and ethnomedicinal products) and their utilization patterns, including the possibility of ecotourism development. The questionnaire-based results have indicated that more than 80% of peri-urban population rely on mangroves for timber and non-timber products and consider them as very important for their livelihoods. However, at the same time, urban households demonstrate limited knowledge on mangrove species and their ecological/economic benefits. Among others, fishing (including the oyster-Crassostrea cf. gasar collection) and tourism are the major income-generating activities found in the TWNP. The age-old practices of agriculture in some parts of the TWNP are due to scarcity of land available for agriculture, increased family size, and alternative sources of income. The recent focus on ecotourism (i.e., boardwalk construction inside the mangroves near Banjul city) received a positive response from the local stakeholders (i.e., users, government, and non-government organizations), with their appropriate roles in sharing the revenue, rights, and responsibilities of this project. Though the guidelines for conservation and management of the TWNP seem to be compatible, the harmony between local people and sustainable resource utilization should be ascertained.

  16. A Quantitative Index of Forest Structural Sustainability

    Directory of Open Access Journals (Sweden)

    Jonathan A. Cale

    2014-07-01

    Full Text Available Forest health is a complex concept including many ecosystem functions, interactions and values. We develop a quantitative system applicable to many forest types to assess tree mortality with respect to stable forest structure and composition. We quantify impacts of observed tree mortality on structure by comparison to baseline mortality, and then develop a system that distinguishes between structurally stable and unstable forests. An empirical multivariate index of structural sustainability and a threshold value (70.6 derived from 22 nontropical tree species’ datasets differentiated structurally sustainable from unsustainable diameter distributions. Twelve of 22 species populations were sustainable with a mean score of 33.2 (median = 27.6. Ten species populations were unsustainable with a mean score of 142.6 (median = 130.1. Among them, Fagus grandifolia, Pinus lambertiana, P. ponderosa, and Nothofagus solandri were attributable to known disturbances; whereas the unsustainability of Abies balsamea, Acer rubrum, Calocedrus decurrens, Picea engelmannii, P. rubens, and Prunus serotina populations were not. This approach provides the ecological framework for rational management decisions using routine inventory data to objectively: determine scope and direction of change in structure and composition, assess excessive or insufficient mortality, compare disturbance impacts in time and space, and prioritize management needs and allocation of scarce resources.

  17. The Influence of Forest Management Regimes on Deforestation in a Central Indian Dry Deciduous Forest Landscape

    Directory of Open Access Journals (Sweden)

    Shivani Agarwal

    2016-08-01

    Full Text Available This research examines the impact of forest management regimes, with various degrees of restriction, on forest conservation in a dry deciduous Indian forest landscape. Forest change is mapped using Landsat satellite images from 1977, 1990, 1999, and 2011. The landscape studied has lost 1478 km2 of dense forest cover between 1977 and 2011, with a maximum loss of 1002 km2 of dense forest between 1977 and 1990. The number of protected forest areas has increased, concomitant with an increase in restrictions on forest access and use outside protected areas. Interviews with residents of 20 randomly selected villages indicate that in the absence of alternatives, rather than reducing their dependence on forests, communities appear to shift their use to other, less protected patches of forest. Pressure shifts seem to be taking place as a consequence of increasing protection, from within protected areas to forests outside, leading to the creation of protected but isolated forest islands within a matrix of overall deforestation, and increased conflict between local residents and forest managers. A broader landscape vision for forest management needs to be developed, that involves local communities with forest protection and enables their decision-making on forest management outside strict protected areas.

  7. Post-Fire Restoration Plan for Sustainable Forest Management in South Korea

    Directory of Open Access Journals (Sweden)

    Soung-Ryoul Ryu

    2017-05-01

    Full Text Available This review was to determine a standard post-fire restoration strategy for use in South Korea according to the magnitude of the damage and the condition of the affected site. The government has strongly enforced reforestation in deforested areas as well as fire prevention and suppression since the 1960s. These efforts have successfully recovered dense even-aged forests over the last five decades. However, high fuel loading and the homogeneous structure have made forests vulnerable to large fires. In recent years, large forest fires have occurred in the eastern coastal region of Korea. Forest fires can significantly influence the economic and social activities of the residents of such affected forest regions. Burned areas may require urgent and long-term restoration strategies, depending on the condition of the affected site. Erosion control is the most important component of an urgent restoration and should be completed before a rainy season to prevent secondary damage such as landslides and sediment runoff in burned areas. Long-term restoration is necessary to renew forest functions such as timber production, water conservation, ecosystem conservation, and recreation for residents. Sound restoration for burned areas is critical for restoring healthy ecological functions of forests and providing economic incentives to local residents.

  9. Integrating spatial modeling, climate change scenarios, invasive species risk, and public perceptions to inform sustainable management in mixed hemlock-hardwood forests in Maine

    Science.gov (United States)

    Dunckel, Kathleen Lois

    Introduced invasive pests and climate change are perhaps the most important and persistent catalyst for changes in forest composition. Infestation and outbreak of the hemlock woolly adelgid (HWA, Adelges tsugae) along the eastern coast of the USA, has led to widespread loss of hemlock (Tsuga canadensis (L.) Carr.), and a shift in tree species composition towards hardwood stands. Maine's forest dominated landscape and position at the leading edge of the HWA invasion provides an excellent opportunity to inform sustainable forest management (SFM) practices by using spatially explicit models to predict current tree species distribution, future range shifts, and solicit broad based feedback from Maine residents about forest management goals and preferences. This paper describes an interdisciplinary study of the ecological and social implications of changes in mixed northern hardwood forests due to disturbance. A two stage mapping approach was used where presence/absence of eastern hemlock is predicted with an overall accuracy of 85% and the continuous distribution (% basal area) was predicted with an accuracy of 83%. Given the importance of climate variables in predicting eastern hemlock, forecasts of future range shifts are possible using data generated through climate scenarios. The NASA Earth Exchange (NEX) Downscaled Climate Projections (NEX-DCP30) dataset was used to model future shifts in the geographic range of eastern hemlock throughout the state of Maine. The results clearly describe a significant shift in eastern hemlock range with gains in total geographic area that is suitable habitat. Sustaining forest systems across the landscape requires not only ecological knowledge, but also the integration of multiple socio-economic criteria as well, including data obtained through broad-based public participation approaches. Here, 3000 Maine residents were surveyed and asked how they: (1) value local forests; (2) view forest management goals and threats to forest

  12. Climate Change Mitigation Through Reduced-Impact Logging and the Hierarchy of Production Forest Management

    Directory of Open Access Journals (Sweden)

    Ben Vickers

    2012-01-01

    Full Text Available The proposed hierarchy of production forest management provides modus operandi for forest concessions to move incrementally towards Sustainable Forest Management (SFM via Reduced-Impact Logging (RIL and forest certification. Financial benefits are sourced in the “Additionality Zone”, financing the rise in the hierarchy and offsetting prohibitive forest and carbon certification costs. RIL carbon registration components consist of developing credible baseline, additionality and leakage arguments around the business-as-usual scenario through the quantification of historical forest inventory and production records, forest infrastructure records and damage to the residual forest. If conventional harvesting is taken as a baseline, research indicates RIL can potentially reduce emissions by approximately 1–7 tCO2e ha−1yr−1. The current market price of USD $7.30 per tCO2e may result in over USD $50 ha−1yr−1 in additional revenue, well above the estimated USD $3–5 ha−1 in carbon transaction costs. Concessions in Sabah Malaysia demonstrate the financial viability of long-term RIL and certification planning. This may act as a basis for future planned forest management activities involving RIL, carbon and forest certification through the hierarchy of production forest management.

  14. The Contribution of Traditional Ecological Knowledge and Practices to Forest Management: The Case of Northeast Asia

    Directory of Open Access Journals (Sweden)

    Seongjun Kim

    2017-12-01

    Full Text Available This study aims to introduce the potential applicability of traditional ecological knowledge and community forestry in Northeast Asia, including China, Japan, and South Korea. In ancient Northeast Asia, forest policies and practices were based on Fengshui (an old Chinese concept regarding the flow of vital forces, with which forests were managed under community forestry. However, these traditional systems diminished in the twentieth century owing to the decline of traditional livelihood systems and extreme deforestation. Recently, legacies from traditional ecological knowledge and community forestry have been revisited and incorporated into forest policies, laws, and management practices because of growing needs for sustainable forest use in China, Japan, and Korea. This reevaluation of traditional ecological knowledge and community forestry has provided empirical data to help improve forestry systems. Although traditional ecological knowledge and community forestry in Northeast Asia have been scarcely theorized, they play a significant role in modifying forest management practices in the face of socioeconomic changes.

    The ecological impacts of changing forest management practices in Europe are poorly understood despite European forests being highly managed. Furthermore, the effects of potential drivers of forest biodiversity decline are rarely considered in concert, thus limiting effective conservation or sustainable forest management. We present a trait-based framework that we use to assess the detrimental impact of multiple land-use and management changes in forests on bird populations across Europe. Major changes to forest habitats occurring in recent decades, and their impact on resource availability for birds were identified. Risk associated with these changes for 52 species of forest birds, defined as the proportion of each species' key resources detrimentally affected through changes in abundance and/or availability, was quantified and compared to their pan-European population growth rates between 1980 and 2009. Relationships between risk and population growth were found to be significantly negative, indicating that resource loss in European forests is an important driver of decline for both resident and migrant birds. Our results demonstrate that coarse quantification of resource use and ecological change can be valuable in understanding causes of biodiversity decline, and thus in informing conservation strategy and policy. Such an approach has good potential to be extended for predictive use in assessing the impact of possible future changes to forest management and to develop more precise indicators of forest health.

    2006-04-01

    Full Text Available Forest management plans were firstly prepared and implemented in Turkey between 1963 and 1973. All forests in Turkey have been managed with timber oriented forest management philosophy; however, there have been some developments about inventory and silviculture techniques for approximately 40 years. Last decade, Turkey participated in Convention of Biological Diversity in Rio (1992 and included in both Pan – European and Near East Region Conventions. Nowadays, Turkish forest management philosophy has changed from timber management to ecosystem-based multiple-use forest planning with the principles of “sustainable forest management” criteria and indicators drafted in a few national and international agreements. Thus, Turkish forestry is underway in a restructuring process. This paper presents evolution of the traditional forest management philosophy in Turkey since 1963. This study was carried out in Artvin Planning Unit. Past two decade planning periods (managed under timber management approach was compared with current case study data used for forest multiple use management approach based on ecosystem in terms of distribution of age class, site class and change of volume and increment.

    The challenge of sustainable forest management is to integrate diverse and sometimes conflicting management objectives. In order to achieve this goal, we need a better understanding of the aspects influencing the preferences of diverse groups and how these groups make trade-offs between different attributes of SFM. We compare the SFM preferences of interest groups in regions with different forest use histories based on the reasoning that the condition of the forest reflects the forest use history of the area. The condition of the forest also shapes an individual's forest values and attitudes. These held values and attitudes are thought to influence SFM preferences. We tested whether the SFM preferences vary amongst the different interest groups within and across regions. We collected data from 252 persons using a choice experiment approach, where participants chose multiple times among different options described by a combination of attributes that are assigned different levels. The novelty of our approach was the use of choice experiments in the assessment of regional preference differences. Given the complexity of inter-regional comparison and the small sample size, this was an exploratory study based on a purposive rather than random sample. Nevertheless, our results suggest that the aggregation of preferences of all individuals within a region does not reveal all information necessary for forest management planning since opposing viewpoints could cancel each other out and lead to an interpretation that does not reflect possibly polarised views. Although based on a small sample size, the preferences of interest groups within a region are generally statistically significantly different from each other; however preferences of interest groups across regions are also significantly different. This illustrates the potential importance of assessing heterogeneity by region and by group.

  8. Redefining Secondary Forests in the Mexican Forest Code: Implications for Management, Restoration, and Conservation

    Directory of Open Access Journals (Sweden)

    Francisco J. Román-Dañobeytia

    2014-05-01

    Full Text Available The Mexican Forest Code establishes structural reference values to differentiate between secondary and old-growth forests and requires a management plan when secondary forests become old-growth and potentially harvestable forests. The implications of this regulation for forest management, restoration, and conservation were assessed in the context of the Calakmul Biosphere Reserve, which is located in the Yucatan Peninsula. The basal area and stem density thresholds currently used by the legislation to differentiate old-growth from secondary forests are 4 m2/ha and 15 trees/ha (trees with a diameter at breast height of >25 cm; however, our research indicates that these values should be increased to 20 m2/ha and 100 trees/ha, respectively. Given that a management plan is required when secondary forests become old-growth forests, many landowners avoid forest-stand development by engaging slash-and-burn agriculture or cattle grazing. We present evidence that deforestation and land degradation may prevent the natural regeneration of late-successional tree species of high ecological and economic importance. Moreover, we discuss the results of this study in the light of an ongoing debate in the Yucatan Peninsula between policy makers, non-governmental organizations (NGOs, landowners and researchers, regarding the modification of this regulation to redefine the concept of acahual (secondary forest and to facilitate forest management and restoration with valuable timber tree species.

  10. The Contribution of Multiple Use Forest Management to Small Farmers’ Annual Incomes in the Eastern Amazon

    2014-06-01

    Full Text Available Small-scale farmers in the Brazilian Amazon collectively hold tenure over more than 12 million ha of permanent forest reserves, as required by the Forest Code. The trade-off between forest conservation and other land uses entails opportunity costs for them and for the country, which have not been sufficiently studied. We assessed the potential income generated by multiple use forest management for farmers and compared it to the income potentially derived from six other agricultural land uses. Income from the forest was from (i logging, carried out by a logging company in partnership with farmers’ associations; and (ii harvesting the seeds of Carapa guianensis (local name andiroba for the production of oil. We then compared the income generated by multiple-use forest management with the income from different types of agrarian systems. According to our calculations in this study, the mean annual economic benefits from multiple forest use are the same as the least productive agrarian system, but only 25% of the annual income generated by the most productive system. Although the income generated by logging may be considered low when calculated on an annual basis and compared to incomes generated by agriculture, the one-time payment after logging is significant (US$5,800 to US$33,508 and could be used to implement more intensive and productive cropping systems such as planting black pepper. The income from forest management could also be used to establish permanent fields in deforested areas for highly productive annual crops using conservation agriculture techniques. These techniques are alternatives to the traditional land use based on periodic clearing of the forest. Nevertheless, the shift in current practices towards adoption of more sustainable conservation agriculture techniques will also require the technical and legal support of the State to help small farmers apply these alternatives, which aim to integrate forest management in

    Despite widespread acceptance of sustainability as the ultimate goal of forest management, perspectives about its meaning, significance, and relevant indicators may still differ. This paper examines local perspectives on sustainability, and evaluates their similarities and differences. A systematic procedure based on criteria of proximity, pre-existing rights, dependency, knowledge of forest management, forestry spirit, daily activity, and legal rights was used to identify a small group of relevant stakeholders representing different groups, institutions, and organizations. Using participatory action research (PAR), stakeholders were asked to identify relevant indicators of sustainable forest management. The indicators identified by each stakeholder were then compared to a consolidated list assembled by field facilitators with respect to whether relevant indicators are present or not. Based on the resulting presence/absence matrix, a statistical tool called the simple matching coefficient was used to estimate the similarity measures among the stakeholders' perspectives. In addition, cluster analysis was used to classify groups of stakeholders depending on their similarities to each other. Finally, hypotheses related to the 'closeness' of perspectives among local communities, non-governmental organizations, a timber company, and government organizations, as revealed by their selection of indicators, were tested. Results show that: (a) local communities have different perceptions in terms of what they consider to be important indicators compared to the NGOs, (b) there are significantly different perceptions between the government and the timber companies, and (c) there are also different perceptions between urban and field-based personnel of the same organization.

  13. On the potential of Kriging for forest management planning

    Energy Technology Data Exchange (ETDEWEB)

    Gunnarsson, F.

    1996-12-31

    Forest management planning aims at fulfilling the overall goals for the forest owner. The economic optimal scheduling of treatments in spatially discrete forest stands, the time dimension, has been thoroughly investigated in research. The spatial dimension is less investigated. Normally, spatially discrete stands are defined as treatment units. These are inventoried using subjective methods with unknown precision. As an alternative to this conventional way to describe the forest, the present investigation used kriging for estimating forest characteristics spatially continuously using georeferenced sample plots. Using stratification by age, several variables interesting for forest management planning displayed spatial autocorrelation, even though the estate was thoroughly managed. No hardwood variables displayed the autocorrelation necessary for using kriging. 20 refs, 6 figs, 2 tabs

  14. Basic problems of management in the sphere of forest relations in retrospect of public prosecutor

    Full Text Available Public administration of forests is one of the most important sectors of ecological public administration at the national and local levels. Forest legislation is the legal basis for management, whose quality and regulatory capacity ensure the effectiveness of state power activities aimed at sustainable use, protection and regeneration of forests. The need for reforming and properly updating forest legislation and law enforcement is long overdue, which is confirmed by scientific studies and actual facts. A basic problem of forest management is the absence of an official definition of «forest» and «urban forest». Problems of forest fire protection and management problems in the forest sector (e.g. related to the provision of forest plots and the sale and purchase of forest stands are widespread. Management problems also cover a mismatch of legislative activity of the competent entities regarding the regulation of forestry relations, the one-time combination of regulatory and supervisory functions in the same bodies, as well as the lack of a single current and objective system of state cadastral registration. The paper mentions peculiarities of identifying legal responsibility for forest offenses. It is noted that office of public prosecutor, being a central supervisory agency of the state due to the nature of its job and position in a system of separation of powers, has vast (if compared with other subjects of administrative relations opportunities to identify, overcome and eliminate the problems of management of forests. The paper considers separate case materials that show an active role of the national public prosecutor’s office in supporting law and order in the examined field. Generalized conclusions are drawn based on the results of the study.

    Leaf litter decomposition is the key ecological process that determines the sustainability of managed forest ecosystems, however very few studies hitherto have investigated this process with respect to silvicultural management practices. The aims of the present study were to investigate the effects of forest management practices on leaf litter decomposition rates, nutrient dynamics (C, N, Mg, K, Ca, P) and the activity of ligninolytic enzymes. We approached these questions using a 473 day long litterbag experiment. We found that age-class beech and spruce forests (high forest management intensity) had significantly higher decomposition rates and nutrient release (most nutrients) than unmanaged deciduous forest reserves (Pforest management (low forest management intensity) exhibited no significant differences in litter decomposition rate, C release, lignin decomposition, and C/N, lignin/N and ligninolytic enzyme patterns compared to the unmanaged deciduous forest reserves, but most nutrient dynamics examined in this study were significantly faster under such near-to-nature forest management practices. Analyzing the activities of ligninolytic enzymes provided evidence that different forest system management practices affect litter decomposition by changing microbial enzyme activities, at least over the investigated time frame of 473 days (laccase, Pforest system management practices can significantly affect important ecological processes and services such as decomposition and nutrient cycling.

  2. Rural aquaculture as a sustainable alternative for forest conservation in the Monarch Butterfly Biosphere Reserve, Mexico.

    Forest conservation plays a significant role in environmental sustainability. In Mexico only 8.48 million ha of forest are used for conservation of biodiversity. Payment for Environmental Services in the Monarch Butterfly Biosphere Reserve, one of the most important national protected areas, contributes to the conservation of these forests. In the Reserve, production of rainbow trout has been important for the rural communities who need to conserve the forest cover in order to maintain the hibernation cycle of the butterfly. Aquaculture is a highly productive activity for these protected areas, since it harnesses the existing water resources. In this study, changes from 1999 to 2012 in vegetation and land-use cover in the El Lindero basin within the Reserve were evaluated in order to determine the conservation status and to consider the feasibility of aquaculture as a means of sustainable development at community level. Evaluation involved stereoscopic interpretation of digital aerial photographs from 1999 to 2012 at 1:10,000 scale, comparative analysis by orthocorrected mosaics and restitution on the mosaics. Between 1999 and 2012, forested land recovered by 28.57 ha (2.70%) at the expense of non-forested areas, although forest degradation was 3.59%. Forest density increased by 16.87%. In the 46 ha outside the Reserve, deforestation spread by 0.26%, and land use change was 0.11%. The trend towards change in forest cover is closely related to conservation programmes, particularly payment for not extracting timber, reforestation campaigns and surveillance, whose effects have been exploited for the development of rural aquaculture; this is a new way to improve the socio-economic status of the population, to avoid logging and to achieve environmental sustainability in the Reserve.

    In the context of advanced valorization of the log residues in the forests of great Congo basin, particularly in East Cameroon, techniques of cogeneration should be applied in order to develop this type of biomass in form of electricity profitable to industries and local populations. Forest concessions FMU (Forest Management Unit) assigned by the Cameroon government state do not promote logs residues resulting from forestry site. These woods are abandoned in forest and parks, whereas they should contribute to production of green energy, alternative to oil/diesel which is responsible for greenhouse effect. Enquiries on diesel use for electrical generator sets show 75000 litres consumption per day in the province; That is to say 20 563 466 Euros per year. In spite of this very high cost, only 40% of the population have access to electricity and the slice that benefit from this is regularly victim of power cut. Considering this assessment, it is evident from our study, circumscribes of 30 forest concessions FMU in activity belonging to 15 forest industries that potential volume of logs residues exploitable in form of electrical and thermal energy is 614 522 m3 per year, equivalent to 361 229 tonnes of residues; giving a possibility in electrical energy of 361 229 MWh and 722 400 MWh in thermal energy

  9. The community resource management area mechanism: a strategy to manage African forest resources for REDD+.

    Asare, Rebecca A; Kyei, Andrew; Mason, John J

    2013-01-01

    Climate change poses a significant threat to Africa, and deforestation rates have increased in recent years. Mitigation initiatives such as REDD+ are widely considered as potentially efficient ways to generate emission reductions (or removals), conserve or sustainably manage forests, and bring benefits to communities, but effective implementation models are lacking. This paper presents the case of Ghana's Community Resource Management Area (CREMA) mechanism, an innovative natural resource governance and landscape-level planning tool that authorizes communities to manage their natural resources for economic and livelihood benefits. This paper argues that while the CREMA was originally developed to facilitate community-based wildlife management and habitat protection, it offers a promising community-based structure and process for managing African forest resources for REDD+. At a theoretical level, it conforms to the ecological, socio-cultural and economic factors that drive resource-users' decision process and practices. And from a practical mitigation standpoint, the CREMA has the potential to help solve many of the key challenges for REDD+ in Africa, including definition of boundaries, smallholder aggregation, free prior and informed consent, ensuring permanence, preventing leakage, clarifying land tenure and carbon rights, as well as enabling equitable benefit-sharing arrangements. Ultimately, CREMA's potential as a forest management and climate change mitigation strategy that generates livelihood benefits for smallholder farmers and forest users will depend upon the willingness of African governments to support the mechanism and give it full legislative backing, and the motivation of communities to adopt the CREMA and integrate democratic decision-making and planning with their traditional values and natural resource management systems.

À ce titre, il est nécessaire de trouver des instruments juridiques, politiques ou économiques susceptibles de gérer cette « ressource-paysage » sur le long terme. Le gouvernement suisse a introduit récemment l’instrument des parcs naturels régionaux, organisés selon le modèle français, dans sa législation de protection de la nature et du paysage. Une mise en regard des nouveaux parcs avec des structures de gestion beaucoup plus anciennes, les bourgeoisies et les corporations, permet de mettre en évidence les forces et les faiblesses de chacun de ces instruments dans leur contribution à résoudre les rivalités d’usage entre acteurs utilisant ou influençant la ressource paysage. Cette comparaison permet de formuler des recommandations pratiques concernant la gestion de cette ressource.The landscape is increasingly perceived as a resource. For this reason, it is necessary to find legal, political and economic instruments that will succeed in managing this "resource landscape" in the long term. The Swiss government recently introduced the instrument of regional nature parks into the legislation governing nature and landscape preservation; the proposed parks are organized on the basis of the French model. The examination of the new parks from the perspective of much older management structures, i.e. the civic municipalities (bourgeoisies and corporations, makes it possible to demonstrate the strengths and weaknesses of each of these instruments in their contribution to the resolution of use rivalries between actors who use or influence the resource landscape. This comparison also enables the formulation of practical recommendations regarding the management of this resource.

    Directory of Open Access Journals (Sweden)

    Moritz Albrecht

    2012-01-01

    Full Text Available The integration of improved environmental or sustainable aspects in forest management is often affiliated with the rise of market-driven governance systems, such as forest certification. In terms of forest resource peripheries, like North-Karelia, Finland, these are often attributed to environmental business and consumer demands from the green Central European markets. While acknowledging these aspects related to the supply chains of wood-based products, this study evaluates the actual perceptions about environmental forest governance and its spaces in the resource peripheries themselves. It displays the perceived changes and practices in forestry by comparing private and corporate ownership and their governance networks. This is accomplished by a qualitative, interview based case study of North Karelian and Finnish forestry actors. Transnational forest governance is hereby treated as a relational space, with forest certification systems as possible technologies used to achieve improved, sustainable forest management. Utilizing the North-Karelian forestry sector, the varying positionalities of actors and institutions within such a relational space shape the knowledge networks, perceptions and decision-making. The study evaluates how these local-global positionalities of actors and individuals shapes their understanding, and guide the direction of sustainable forest management in Finland while it (re-produces opposing regimes of practice. With the discourse on forest certification being twofold, a more complex picture emerges if aspects of even- versus uneven-aged forest management in Finland are integrated. Shaped by the actor’s positionalities and related knowledge networks, perceptions regarding the quality of forest management practices and technologies used to achieve sustainability differ and thereby shape governance processes. The green markets are not perceived as the main driving force and a strong governmental influence, particularly

    Directory of Open Access Journals (Sweden)

    Brenda C. McComb

    2007-12-01

    Full Text Available To understand the potential effects of forest policies on sustaining biological diversity at broad scales, we used spatial simulation models to evaluate current and potential future habitat availability over 100 yr for three focal species: Pacific Fisher (Martes pennanti, Pileated Woodpecker (Dryocopus pileatus, and Warbling Vireo (Vireo gilvus. The habitats of these species represent a broad range of spatial scales and forest types. Area of habitat for fishers and Pileated Woodpeckers is predicted to increase over time under current forest land management policies. Habitat for Warbling Vireos is predicted to decline. These patterns are consistent with past analyses that predicted declines in diverse early successional forests and hardwood forests and increases in late-successional forests under current and two alternative policies. Land ownership influenced the spatial arrangement of habitat for all three focal species. Public lands subsidized habitat for wide-ranging species on adjacent private lands. A land use policy that required greater green tree retention on private lands seemed to result in modest increases in habitat quality over 100 yr for Pileated Woodpeckers. Thinning of plantations on federal lands had little effect on these focal species. Policy analyses such as these highlight incongruities between historic habitat patterns and contemporary spatial and temporal scales of habitat in managed landscapes.

  2. Sustainability Reporting in Higher Education: Interconnecting the Reporting Process and Organisational Change Management for Sustainability

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Although there has been a considerable increase in the publication of sustainability reports in the corporate world in the last decade, sustainability reporting in higher education institutions is still in its early stages. This study’s aim was to explore the relationship between sustainability reporting and organizational change management for sustainability in higher education. A survey was sent to higher education institutions worldwide that have published sustainability reports in the last ten years. The survey was answered by 23 institutions out of a total of 64. The findings showed that sustainability reporting has been predominantly driven by internal motivations, and that the sustainability reporting process leads to incremental changes, such as an increase in awareness of sustainability and improvements in communication with internal stakeholders. Some factors impeding change are the absence of an external stakeholder engagement process, the lack of inclusion of material impacts in reports, and the lack of institutionalization of sustainability reporting in the higher education system. The paper proposes that higher education institutions need to consider sustainability reporting as a dynamic tool to plan sustainability changes, and not just as a communication activity.

  3. Sustainable Risk Management in the Banking Sector

    Županović Ivo

    2014-01-01

    Full Text Available The globalization of financial markets and negative consequences of the financial crisis resulted in negative connotations in the operation of many financial institutions, businesses and citizens and imposed the need to implement appropriate risk management measures in the banking sector. Evolution of the financial sector makes a lot of news in the field of risk management and particularly the modelling of market, credit and operational risk. The main methodology for risk management is the value-at-risk, which is used in practice with other techniques such as the capital- at-risk method in order to minimize business risks and achieve optimal results in the banking and, generally, financial operations. Accordingly, at all levels of governance in the banking sector, there are prudential policies in place governing the management of all types of financial and operational risks. Based on the abovementioned, the focus of the examination was on the above postulate, and prompt recognition, control and proper management of banking risks.

  4. Human resource management in the construction industry – Sustainability competencies

    Directory of Open Access Journals (Sweden)

    Renard Yung Jhien Siew

    2014-06-01

    Full Text Available While environmental sustainability has been the subject of much debate in the last decade, it was not until recently that attention started to shift towards human resource management as an enabler for sustainability.  Yet, this is still a relatively under researched area.  Much is still unknown about the role of an individual worker in contributing towards sustainable development.  This paper addresses the gap by proposing a framework to measure sustainability competencies of employees within the construction industry sector.  As part of the framework, four proficiency levels together with relevant descriptions are defined for a total of eight sustainability competencies.  Suggested proficiency levels are then mapped to main construction related jobs based on the framework.  An example is also given to illustrate the manner in which competencies should be assessed.  This framework is original and of practical use to construction managers and human resource practitioners.

    Valade, Aude; Luyssaert, Sebastiaan; Bellassen, Valentin; Vallet, Patrick; Martin, Manuel

    2015-04-01

    International agreements now recognize the role of forest in the mitigation of climate change through the levers of in-situ sequestration, storage in products and energy and product substitution. These three strategies of carbon management are often antagonistic and it is still not clear which strategy would have the most significant impact on atmospheric carbon concentrations. With a focus on France, this study compares several scenarios of forest management in terms of their effect on the overall carbon budget from trees to wood-products. We elaborated four scenarios of forest management that target different wood production objectives. One scenario is 'Business as usual' and reproduces the current forest management and wood production levels. Two scenarios target an increase in bioenergy wood production, with either long-term or short-term goals. One scenario aims at increasing the production of timber for construction. For this, an empirical regression model was developed building on the rich French inventory database. The model can project the current forest resource at a time horizon of 20 years for characteristic variables diameter, standing volume, above-ground biomass, stand age. A simplified life-cycle analysis provides a full carbon budget for each scenario from forest management to wood use and allows the identification of the scenario that most reduces carbon emissions.

    2009-07-01

    In the last decade, forestry policies in Spain have undergone changes needed to comply with the European and world directives on forest conservation. The elaboration of strategic plans has to take into account the State organization (Central and Autonomous Regional Governments share the responsibilities), resulting in agreed documents, effective at a national level and fulfilling the peculiarities and aspirations of each region. The most recent development has been the elaboration of a Strategy for Conservation and Sustainable Use of Forest Genetic Resources, which can be seen as a consequence of, among other factors, the implementation of the Spanish Strategy for Conservation and Sustainable Use of Biodiversity along with Spains participation in the European Forest Genetic Resources Programme. This document arose from the lack of approaches to the conservation of population diversity of forest species in the current policies, and as a means to promote and coordinate activities on conservation and use of genetic resources. The Strategy has been arranged through a participative process involving the Forest Administration, Research Centres and Universities. The document includes a definition of priorities and proposals of activities, which are mainly focused on optimising the efficiency of existing tools and infrastructures and on increasing synergy among different initiatives. Implementation of the Strategy is expected to occur through the development of National Action Plans. Finally, coordination mechanisms must be enhanced in order to maintain the levels of cooperation achieved during the elaboration process. (Author) 18 refs.

    Ekstrand, Sam; Loefmark, Magnus; Johansson, Desiree

    2001-02-01

    The objective of this project was to develop methods for estimation of forest stand variables using digital analysis of near infrared air photography. Near Infrared air photography covering an area 200 km northwest of Stockholm was scanned and ortho rectified. Methods for digital classification, normalisation of view angle effects and estimation of parameters such as timber volume, stand density, crown coverage, species composition, defoliation and number of dead or dying trees have been developed. Major results were that the functions for normalisation on view angle effects on tree size as viewed from the focal point strongly improved the stand estimates. Timber volume, stand density, species composition as well as the ecological variables were estimated with accuracies comparable to those of subjective field inventory methods. In spite of the photography being of high quality, differences in colour between flight lines gave problems with separation of pine and spruce. This may be solved using post-classification manual editing, but will cause an increase in costs. In the future, digital cameras or calibration lamps within the photograph could further reduce this problem.

  19. Influence of different forest system management practices on leaf litter decomposition rates, nutrient dynamics and the activity of ligninolytic enzymes: a case study from central European forests.

    Full Text Available Leaf litter decomposition is the key ecological process that determines the sustainability of managed forest ecosystems, however very few studies hitherto have investigated this process with respect to silvicultural management practices. The aims of the present study were to investigate the effects of forest management practices on leaf litter decomposition rates, nutrient dynamics (C, N, Mg, K, Ca, P and the activity of ligninolytic enzymes. We approached these questions using a 473 day long litterbag experiment. We found that age-class beech and spruce forests (high forest management intensity had significantly higher decomposition rates and nutrient release (most nutrients than unmanaged deciduous forest reserves (P<0.05. The site with near-to-nature forest management (low forest management intensity exhibited no significant differences in litter decomposition rate, C release, lignin decomposition, and C/N, lignin/N and ligninolytic enzyme patterns compared to the unmanaged deciduous forest reserves, but most nutrient dynamics examined in this study were significantly faster under such near-to-nature forest management practices. Analyzing the activities of ligninolytic enzymes provided evidence that different forest system management practices affect litter decomposition by changing microbial enzyme activities, at least over the investigated time frame of 473 days (laccase, P<0.0001; manganese peroxidase (MnP, P = 0.0260. Our results also indicate that lignin decomposition is the rate limiting step in leaf litter decomposition and that MnP is one of the key oxidative enzymes of litter degradation. We demonstrate here that forest system management practices can significantly affect important ecological processes and services such as decomposition and nutrient cycling.

    Conservation International (CI) has a decade of experience developing near real-time fire and deforestation monitoring and forecasting systems that channel monitoring information from satellite observations directly to national and sub-national government agencies, Non-Government Organizations (NGOs), and local communities. These systems are used to strengthen forest surveillance and monitoring, fire management and prevention, protected areas management and sustainable land use planning. With support from a NASA Wildland Fires grant, in September 2013 CI will launch a brand new near real-time alert system (FIRECAST) to better meet the outstanding needs and challenges users face in addressing ecosystem degradation from wildland fire and illegal forest activities. Outreach efforts and user feedback have indicated the need for seasonal fire forecasts for effective land use planning, faster alert delivery to enhance response to illegal forest activities, and expanded forest monitoring capabilities that enable proactive responses and that strengthen forest conservation and sustainable development actions. The new FIRECAST system addresses these challenges by integrating the current fire alert and deforestation systems and adding improved ecological forecasting of fire risk; expanding data exchange capabilities with mobile technologies; and delivering a deforestation alert product that can inform policies related to land use management and Reduced Emissions from Deforestation and forest Degradation (REDD+). In addition to demonstrating the capabilities of this new real-time alert system, we also highlight how coordination with host-country institutions enhances the system's capacity to address the implementation needs of REDD+ forest carbon projects, improve tropical forest management, strengthen environmental law enforcement, and facilitate the uptake of near real-time satellite monitoring data into business practices of these national/sub-national institutions.

    2016-07-01

    Full Text Available The world’s habitat is being deteriorated despite of the precautions taken. Construction industry is among the industries which highly effect the environment adversely not only through its outputs but also through the construction process and its inputs. The main focus in dealing with the reduction of its footprint has been on sustainable building certificates which mainly analyse the output of the construction activies. There is need to analyse the construction supply chain as a whole and to embed sustainability dynamics in construction supply chain management. Lean construction project management contributes to the reduction of the environmental footprint of the construction industry, enabling reduction in waste, and increasing value added activities. For this reason, based on an in depth literature review, this paper analyses and establishes the principles of the integration of the sustainability dynamics into lean construction supply chain management.

  9. Does the Establishment of Sustainable Use Reserves Affect Fire Management in the Humid Tropics?

    Directory of Open Access Journals (Sweden)

    Rachel Carmenta

    Full Text Available Tropical forests are experiencing a growing fire problem driven by climatic change, agricultural expansion and forest degradation. Protected areas are an important feature of forest protection strategies, and sustainable use reserves (SURs may be reducing fire prevalence since they promote sustainable livelihoods and resource management. However, the use of fire in swidden agriculture, and other forms of land management, may be undermining the effectiveness of SURs in meeting their conservation and sustainable development goals. We analyse MODIS derived hot pixels, TRMM rainfall data, Terra-Class land cover data, socio-ecological data from the Brazilian agro-census and the spatial extent of rivers and roads to evaluate whether the designation of SURs reduces fire occurrence in the Brazilian Amazon. Specifically, we ask (1 a. Is SUR location (i.e., de facto or (1 b. designation (i.e. de jure the driving factor affecting performance in terms of the spatial density of fires?, and (2, Does SUR creation affect fire management (i.e., the timing of fires in relation to previous rainfall? We demonstrate that pre-protection baselines are crucial for understanding reserve performance. We show that reserve creation had no discernible impact on fire density, and that fires were less prevalent in SURs due to their characteristics of sparser human settlement and remoteness, rather than their status de jure. In addition, the timing of fires in relation to rainfall, indicative of local fire management and adherence to environmental law, did not improve following SUR creation. These results challenge the notion that SURs promote environmentally sensitive fire-management, and suggest that SURs in Amazonia will require special attention if they are to curtail future accidental wildfires, particularly as plans to expand the road infrastructure throughout the region are realised.

    2015-03-15

    Community resilience, the capacity of a community to adapt to change in ways that result in positive impacts on its well-being, is increasingly used as a framework for understanding and enhancing the sustainability of forest-dependent communities as social-ecological systems. However, studies linking community resilience to the implementation of forest management programs are limited. This study uses community resilience literature and analyzes data collected from interviews to study barriers of forest-dependent communities of collaborative forest management (CFM) in two forest-dependent communities in the Ashanti region of Ghana. Analysis revealed the barriers in community response to CFM programs in these two communities comprise institutional shortfalls in the design and implementation of the CFM program that have constrained the incentives, capacity and opportunities for communities to successfully adapt to the program. The paper offers recommendations on how the CFM program can contribute to building the resilience of communities in managing their forests. The first is to build institutional capacity of communities to play an active role in forest governance, and the second is the prioritization of well-being and livelihood enhancement as forest management goals.

  11. Managing the forest for more than the trees: effects of experimental timber harvest on forest Lepidoptera.

    Summerville, Keith S

    2011-04-01

    Studies of the effects of timber harvest on forest insect communities have rarely considered how disturbance from a range of harvest levels interacts with temporal variation in species diversity to affect community resistance to change. Here I report the results of a landscape-scale, before-and-after, treatment-control experiment designed to test how communities of forest Lepidoptera experience (1) changes in species richness and composition and (2) shifts in species dominance one year after logging. I sampled Lepidoptera from 20 forest stands allocated to three harvest treatments (control, even-aged shelterwood or clearcuts, and uneven-aged group selection cuts) within three watersheds at Morgan-Monroe State Forest, Indiana, USA. Moths were sampled from all forest stands one year prior to harvest in 2007 and immediately post-harvest in 2009. Species composition was most significantly affected by temporal variation between years, although uneven-aged management also caused significant changes in lepidopteran community structure. Furthermore, species richness of Lepidoptera was higher in 2007 compared to 2009 across all watersheds and forest stands. The decrease in species richness between years, however, was much larger in even-aged and uneven-aged management units compared to the control. Furthermore, matrix stands within the even-aged management unit demonstrated the highest resistance to species loss within any management unit. Species dominance was highly resistant to effects of timber harvest, with pre- and post-harvest values for Simpson diversity nearly invariant. Counter to prediction, however, the suite of dominant taxa differed dramatically among the three management units post-harvest. My results suggest that temporal variation may have strong interactions with timber harvest, precipitating loss of nearly 50% species richness from managed stands regardless of harvest level. Even-aged management, however, appeared to leave the smallest "footprint" on moth

  15. Factors Influencing Adaptive Capacity in the Reorganization of Forest Management in Alaska

    Directory of Open Access Journals (Sweden)

    Colin Beier

    2011-03-01

    Full Text Available Several studies of U.S. National Forests suggest that declines of their associated forest products industries were driven by synergistic changes in federal governance and market conditions during the late 20th century. In Alaska, dramatic shifts in the economic and political settings of the Tongass National Forest (Tongass drove changes in governance leading to collapse of an industrial forest management system in the early 1990s. However, 15 years since collapse, the reorganization of Tongass governance to reflect 'new' economic and political realities has not progressed. To understand both the factors that hinder institutional change (inertia and the factors that enable progress toward reorganization (adaptation, I analyzed how Tongass forest management, specifically timber sale planning, has responded to changes in market conditions, local industry structure, and larger-scale political governance. Inertia was evidenced by continued emphasis on even-aged management and large-scale harvesting, i.e., the retention of an industrial forestry philosophy that, in the current political situation, yields mostly litigation and appeals, and relatively few forest products. Adaptation was evidenced by flexibility in harvest methods, a willingness to meet local demand instead of political targets, and a growing degree of cooperation with environmental advocacy groups. New partnerships, markets, and political leaders at state and national levels can frame a new blueprint for reorganization of Tongass management toward a more sustainable future.

Improved data collection, quality control, analysis, and data management will provide a firm basis for future scientific understanding of the East Mediterranean coast of Turkey and will support long-term management. Various innovative procedures were proposed for a promising ecosystem-based approach to manage coastal wetlands in the Mediterranean: remote data acquisition with new technologies; environmental quality monitoring program that will provide a baseline for monitoring; linking a Geographic Information System (GIS) with natural resource management decision routines in the context of operational wetlands, fisheries, tourism management system; environmental sensitivity analysis to ensure that permitted developments are environmentally sustainable; and use of natural species to restore the wetlands and coastal dunes and sustain the system processes. The proposed management scheme will benefit the scientific community in the Mediterranean and the management/planning community in Eastern Turkey.

    China's forest cover has been increasing in the past three decades, which is in sharp contrast to rapid declines in other natural resources. Understanding the mechanisms of forest recovery and their effects is essential for sustaining forests in China and elsewhere. Some studies suggest that imports of forest products have contributed to the increase in forest cover of China and the decline in forest cover of exporting countries. However, it is not clear whether other countries beyond the exp...

    Full Text Available This paper describes one of the major challenges of the future: the sustainable development of the society. Sustainability is now increasingly recognized as central to the growth of emerging market economies. For the banking sector, this represents both a demand for greater social and environmental responsibility as well as a new landscape of business opportunity. Several years ago, the main part of the banks did not consider the social and environmental problems relevant for their operations. Recently, the banks began to realize the major impact of the sustainable development over the way of ulterior development of the society and, implicitly over the way of creating of the banking value in the future. In this context, the development of a banking management system, based on sustainable principles represents one of the provocations of these days.Starting from literature in the sustainable banking management field in this paper are presented several relevant issues related to risk management in the context of sustainable banking financing: the need to implement the sustainable management principles in financial and banking industry; the role of banks in sustainable development of society; social and environmental risk management policies, events that have shaped the role of the banking sector in sustainable development; international standards regarding sustainable banking management such us: Equator Principles for sustainable investment projects’ financing or GRI principles for sustainable reporting. Furthermore, we developed a practical case study related to the implementation of sustainable banking management at Bank of America.

  1. Evaluating the impact of abrupt changes in forest policy and management practices on landscape dynamics: analysis of a Landsat image time series in the Atlantic Northern Forest.

    Sustainable forest management is based on functional relationships between management actions, landscape conditions, and forest values. Changes in management practices make it fundamentally more difficult to study these relationships because the impacts of current practices are difficult to disentangle from the persistent influences of past practices. Within the Atlantic Northern Forest of Maine, U.S.A., forest policy and management practices changed abruptly in the early 1990s. During the 1970s-1980s, a severe insect outbreak stimulated salvage clearcutting of large contiguous tracts of spruce-fir forest. Following clearcut regulation in 1991, management practices shifted abruptly to near complete dependence on partial harvesting. Using a time series of Landsat satellite imagery (1973-2010) we assessed cumulative landscape change caused by these very different management regimes. We modeled predominant temporal patterns of harvesting and segmented a large study area into groups of landscape units with similar harvest histories. Time series of landscape composition and configuration metrics averaged within groups revealed differences in landscape dynamics caused by differences in management history. In some groups (24% of landscape units), salvage caused rapid loss and subdivision of intact mature forest. Persistent landscape change was created by large salvage clearcuts (often averaging > 100 ha) and conversion of spruce-fir to deciduous and mixed forest. In groups that were little affected by salvage (56% of landscape units), contemporary partial harvesting caused loss and subdivision of intact mature forest at even greater rates. Patch shape complexity and edge density reached high levels even where cumulative harvest area was relatively low. Contemporary practices introduced more numerous and much smaller patches of stand-replacing disturbance (typically averaging Management regimes impacted different areas to different degrees, producing different trajectories

    2009-07-01

    This study describes the state of coarse dead wood (CDW) in the Forest Reserve and the Managed Forest zones of northern conifer-broad-leaved mixed forest. The results showed mean total CDW volumes in the ranges 30,05{+-}11,06 m3/ha in the Forest Reserve (6,33{+-}2,98% of the LW volume), and 9,31{+-}2,84 m3/ha in the Managed Forest (1,96{+-}0,84% of the LW volume). The total CDW volume was 3,22 times higher in the Forest Reserve than in the Managed Forest. The CDW{sub l}og1 and CDW{sub s}nag1 were the most abundant CDW decay classes, whilst CDW{sub l}og2 and CDW{sub s}nag2 were the lowest. Comparisons of ratios between the Managed Forest and the Forest Reserve with abundant decay classes CDW{sub l}og1 and CDW{sub s}nag1 indicated large differences. The CDW{sub l}og1 volume was 4,09 times higher, and the CDW{sub s}nag1 volume was 3,68 times greater in the Forest Reserve than in the Managed Forest. The ratio of different CWD classes in the Managed Forest to CWD classes in the Reserve Forest confirms the pattern. In both Managed and Reserve Forest zones there is balance between total CDW{sub l}ogs and total CDW{sub s}nags, but the differences between total CDW{sub l}ogs and total CDW{sub s}nags was not statistically significant. The total CDW volume was significantly dependent on the forest management system. The system influenced amount and diversity of CDW. In commercially managed forest the abundance and structure of CDW retained is a compromise between the needs of timber production and nature conservation. (Author) 38 refs.

    Full Text Available With regard to forest management, rural livelihood, and poverty in India, it is often debated that JFM regime is not delivering livelihood functions of the forests to their dependents. This paper examines the state and scale of two decades old people-centric JFM system of India, and analyses the reasons with their indicators to shade off its shine in reducing povertyamong forest dependent people in several parts of the country. Paper also iscuss, how and to what extent, adoption of a multi-agency linked Collaborative Forest Management (CFM system could be a better strategy over JFM regime to reassure delivery of livelihood functions of the forests to their dependents in rural India. Arguments in this communication are intended to provide forest managers and policy-makers with necessary input to consider some location specific forest based entrepreneurial activities in CFM mode to provide a continuous source of small income to forest dependent people to ensure long lasting success of their forest management endeavours. Paper concludes with a recommendation to convert unviable JFM areas of India into a multiagency linked CFM system in a phased manner.

    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.

    Full Text Available Forests contribute immensely to economic and social development through formal trade in timber environmental services non- timber forest products safety net spiritual and aesthetic value. Wood is a key source of energy that has been used for millennia for cooking boiling water lighting and heating. Today about 2.5billion people depend on biomass energy for cooking and heating with 87 of this energy being provided by wood. In sub-Saharan African more than 90 of the population relies on wood fire that is firewood and charcoal as their primary source of domestic energy. Over 80 of urban householders and small industries use charcoal and firewood as their source of energy. Despite their numerous importance Africas forest continue to decline rapidly due to increase in agricultural practices into forest lands population growth and urbanization increased poverty high dependence on natural resources for subsistence and income through forest. The study centred on the implications of fuel wood demand on forest conservation in sub-Sahara Africa - a regional focus on Akure metropolitan area Ondo State. The specific objectives of the paper were to identify firewood consumption pattern in Akure metropolitan area and factors responsible for increased fuelwood demand in the study area. The paper adopted direct observation oral interview and 0.05 of the study area as sample size for the study. The study observed lack of adequate alternative poor implementation and enforcement of government regulation on forestry poverty and poor awareness on the menace of forest depletion among others. The paper posited provision of alternative fuel with subsidy regular awareness campaign proper monitoring implementation and enforcement of forest regulations with a view to achieving sustainable conservation.

  7. Indicators and tools for assessing sustainability impacts of the forest bioeconomy

    Full Text Available The sustainable use of renewable resources has become an important issue worldwide in the move towards a less fossil-fuel-intensive future. Mainstream method for fulfilling this aim is to increase the share of renewable energy and materials to substitute fossil fuels and to become fully independent from fossil fuels over the long-term. However, the environmental sustainability of this endeavor has been questioned. In addition, economic and social sustainability issues are also much debated topics in this particular context. Forest resources are often thought to contribute partially to achieving a so-called “carbon-neutral society”. In this review, we discuss sustainability issues of using forest biomass. We present several sustainability indicators for ecological, economic and social dimensions and discuss the issues in applying them in sustainability impact assessments (SIAs. We also present a number of tools and methods previously used in conducting SIAs. We approach our study from the perspective of the Finnish forestry; in addition, various aspects regarding the application of SIAs in a broader context are also presented. One of the key conclusions of the study is that although sufficient data are available to measure many indicators accurately, the impacts may be very difficult to assess (e.g. impact of greenhouse gases on biodiversity for conducting a holistic SIA. Furthermore, some indicators, such as “biodiversity”, are difficult to quantify in the first place. Therefore, a mix of different methods, such as Multi-criteria Assessment, Life-cycle Assessment or Cost-Benefit Analysis, as well as different approaches (e.g. thresholds and strong/weak sustainability are needed in aggregating the results of the impacts. SIAs are important in supporting and improving the acceptability of decision-making, but a certain degree of uncertainty will always have to be tolerated.

    Full Text Available Background: The issue of managing sustainability in supply chain seems to be more and more complex. There are many aspects that need to be taken into consideration when planning, implementing and monitoring environmental and social conditions of supply chains. Despite many works, already published, on the concept of sustainable development (SD is seems that the issue of assessment and especially the issue of maturity in the light of the SD concept is still not developed enough. Methods: The general aim of the paper is the analysis of the maturity issue in the context of sustainability. The main objective is to conceptualize the idea of maturity in sustainable supply chain. Beside the literature research the own proposition of theoretical model was described. Results: The article describes the issue of maturity as an element of managing sustainable development in the supply chain. The author presented a theoretical model of the maturity. Moreover the author gave some recommendations how to manage the sustainability issues in supply chain in more mature approach and introduced some useful tools among which are: certification, code of conduct and code of ethics, audits, projects etc. Conclusions: The issue of maturity seems to be very useful for proper understanding the idea of sustainable development in supply chain. The developed model can be used as self-assessment method to check at which level of implementation the idea of SD is analyzed in supply chain. Furthermore, the next phase of the planned research in form of practical verification of the model was advised as well as a research of identification of new factors and tools in analyzed area.

  9. A Forest Planning Approach with Respect to the Creation of Overmature Reserved Areas in Managed Forests

    Jan Kašpar

    2015-02-01

    Full Text Available Forest harvest planning to maximize economic benefits also has to consider additional criteria such as the biodiversity functioning of the managed forest. The biodiversity requirements are determined by the size, shape, and distribution of harvest units and forest stands. A multiple criteria approach is presented where the harvesting volume is maximized while the environmental aspects are also considered. Multiple criteria programming and integer programming techniques are used to find an optimal program of forest harvesting with respect to both economic and environmental requirements. The practicality of the model is shown in a case study for one particular forest management unit. Different optimal solutions are calculated depending on changes made to the criteria weights. This model includes strict spatial constraints, multiple objective functions with three objectives, and alternative solutions according to the real manager’s priority. The results show that the spatial pattern and other spatial demands affect the harvest possibilities. It was confirmed that a compromise solution from both forest management and nature conservation could be achieved using the presented harvest scheduling approach.

    Bolis, Ivan; Brunoro, Claudio; Sznelwar, Laerte Idal

    2012-01-01

    Based on the concepts of sustainability and knowledge management, this article seeks to identify points of contact between the two themes through an exploratory study of existing literature. The first objective is to find, in international literature, the largest number of papers jointly related to the theme of knowledge management and sustainability. In these documents, the authors looked at the kind of relationship existing between the two themes and what the benefits introduced in organizations are. Based on an ergonomic point of view, the second objective of this article is to analyze the role of the worker (whether at the strategic or operational level) and his importance in this context. The results demonstrate that there is very little literature that addresses the two themes together. The few papers found, however, can be said to show the many advantages of introducing sustainability policies supported by adequate knowledge management. Very little has been studied with regards to the role of workers, which could be interpreted as meaning that little importance is given to the proactive role they may play. On the other hand, there is a high potential for future research in these areas, based on the high level of consideration of workers in knowledge management and sustainability literature, as well as in literature in the areas of ergonomics and sociology.

    The project aimed to investigate the accessibility of forest resources in Northwest (NW) Russia, the impacts of both Scandinavian and current Russian forest management and wood harvesting on ecologically, socially and economically sustainable forestry, and to enhance the development of sustainable forest management and wood harvesting methods for NW Russia. The research group found both positive trends, but also development needs in forest management in Northwest Russia. Since 1993, the area of lands without forest vegetation needing forest regeneration has decreased to a half. On the other hand, in 1999-2006 almost every fifth hectare of clear felling was left without active forest regeneration measures. Moreover, the extent of intermediate felling has been insufficient being only about fifth of the annual allowable area and 9% of the total timber harvesting volume. Wood harvesting has been rather stable last 10 years in NW Russia, at the level of about 40 million m3 per year. Less than half of the annual allowable cut is utilised and most of the round wood is produced by large and medium sized logging companies. Traditional full-tree and tree-length harvesting methods and systems are still dominating in most of the regions even though use of cut-to-length method is becoming more common. Several factors hamper development of wood harvesting, including for example weak production infrastructure, weak road network, lack of own turnover means in companies, low quality in harvester and forwarder operator trainging, and increasing variable costs. Scenario analysis indicate that mature and over mature forests in NW Russia are able to secure wood supply at the current levels for the next 50 years, but that intensification of forest management would allow to substantially increase annual fellings. The discrepancy between forest resources and their accessibility has been regarded as one main problem of forest management. Good infrastructure is essential for harvesting

  3. Carbon profile of the managed forest sector in Canada in the 20th century: sink or source?

    2014-08-19

    Canada contains 10% of global forests and has been one of the world's largest harvested wood products (HWP) producers. Therefore, Canada's managed forest sector, the managed forest area and HWP, has the potential to significantly increase or reduce atmospheric greenhouse gases. Using the most comprehensive carbon balance analysis to date, this study shows Canada's managed forest area and resulting HWP were a sink of 7510 and 849 teragrams carbon (TgC), respectively, in the period 1901-2010, exceeding Canada's fossil fuel-based emissions over this period (7333 TgC). If Canadian HWP were not produced and used for residential construction, and instead more energy intensive materials were used, there would have been an additional 790 TgC fossil fuel-based emissions. Because the forest carbon increases in the 20th century were mainly due to younger growing forests that resulted from disturbances in the 19th century, and future increases in forest carbon stocks appear uncertain, in coming decades most of the mitigation contribution from Canadian forests will likely accrue from wood substitution that reduces fossil fuel-based emissions and stores carbon, so long as those forests are managed sustainably.

    Paul H. Gobster

    1999-01-01

    Although aesthetics and ecological sustainability are two highly regared values of forest landscapes, practices developed to manage forests for these values can sometimes conflict with one another. In this paper I argue that such conflicts are rooted in our conception of forest aesthetics as scenery, and propose that a normative, "ecological aesthetic" based...

  14. Managing forests in a changing world: the need for a systemic approach. A review

    2017-05-01

    Full Text Available Aim of study: The paper is a scientific commented discussion with the aim of defining a framework which allows both a comprehensive vision of forest dynamics, as well as an adaptive management approach and policy procedures more suited to a changing and inherently unpredictable world. Main results: We identify the main challenges facing forestry in relation to recent developments in forestry thinking, i.e. the paradox of aiming at sustainability in a changing environment, a shifting perception of the relationship between ecological and social systems, the recognition of forest ecosystems as complex adaptive systems, the need for integrating the social and ecological dimensions of forestry into a single framework, and the growing awareness of the importance of the ethical approach to the forest. We propose the concept of “systemic forestry” as a paradigm for better understanding forest dynamics and for guiding management and public actions at various levels. We compare the systemic approach with different silvicultural and forest management approaches which have been proposed in the last decades. Research highlights: Our analysis shows that a systemic approach to forestry has five main consequences: 1. forestry is viewed as a part of landscape dynamics through a multi-sectoral coordination, 2. the logic of action changes from norm to process, 3. conservation is a dynamic search for resilience, 4. multi-functionality is achieved through a multi-entries approach integrating ecological, social and economic components of sustainability, 5. forestry institutions are reframed to address the issue of changing interactions among actors, 6. a change in the ethical approach to the forest is needed.

    Balancing forest harvesting and restoration is critical for forest ecosystem management. In this study, we used LANDIS, a spatially explicit forest landscape model, to evaluate the effects of 21 alternative forest management initiatives which were drafted for forests in the upstream region of the Hun River in northeastern China. These management initiatives included a wide range of planting and harvest intensities for Pinus koraiensis, the historically dominant tree species in the region. Multivariate analysis of variance, Shannon's Diversity Index, and planting efficiency (which indicates how many cells of the target species at the final year benefit from per-cell of the planting trees) estimates were used as indicators to analyze the effects of planting and harvesting regimes on forests in the region. The results showed that the following: (1) Increased planting intensity, although augmenting the coverage of P. koraiensis, was accompanied by decreases in planting efficiency and forest diversity. (2) While selective harvesting could increase forest diversity, the abrupt increase of early succession species accompanying this method merits attention. (3) Stimulating rapid forest succession may not be a good management strategy, since the climax species would crowd out other species which are likely more adapted to future climatic conditions in the long run. In light of the above, we suggest a combination of 30% planting intensity with selective harvesting of 50% and 70% of primary and secondary timber species, respectively, as the most effective management regime in this area. In the long run this would accelerate the ultimate dominance of P. koraiensis in the forest via a more effective rate of planting, while maintaining a higher degree of forest diversity. These results are particularly useful for forest managers constrained by limited financial and labor resources who must deal with conflicts between forest harvesting and restoration. PMID:22723930

  19. Keep wetlands wet: the myth of sustainable development of tropical peatlands - implications for policies and management.

    2017-02-01

    Pristine tropical peat swamp forests (PSFs) represent a unique wetland ecosystem of distinctive hydrology which support unique biodiversity and globally significant stores of soil carbon. Yet in Indonesia and Malaysia, home to 56% of the world's tropical peatland, they are subject to considerable developmental pressures, including widespread drainage to support agricultural needs. In this article, we review the ecology behind the functioning and ecosystem services provided by PSFs, with a particular focus on hydrological processes as well as the role of the forest itself in maintaining those services. Drawing on this, we review the suitability of current policy frameworks and consider the efficacy of their implementation. We suggest that policies in Malaysia and Indonesia are often based around the narrative of oil palm and other major monocrops as drivers of prosperity and development. However, we also argue that this narrative is also being supported by a priori claims concerning the possibility of sustainability of peat swamp exploitation via drainage-based agriculture through the adherence to best management practices. We discuss how this limits their efficacy, uptake and the political will towards enforcement. Further, we consider how both narratives (prosperity and sustainability) clearly exclude important considerations concerning the ecosystem value of tropical PSFs which are dependent on their unimpacted hydrology. Current research clearly shows that the actual debate should be focused not on how to develop drainage-based plantations sustainably, but on whether the sustainable conversion to drainage-based systems is possible at all. © 2016 John Wiley & Sons Ltd.

  8. Indigenous knowledge of Zigi community and forest management decision-making: a perspective of community forest interaction

    Directory of Open Access Journals (Sweden)

    Bwagalilo Fadhilia

    2016-03-01

    Full Text Available Indigenous knowledge (IK regarding forests has existed for a long time and has defined community’s forests interaction in various areas. This interaction has resulted in knowledge developed by indigenous communities that has been used to manage their interaction with the forests. However, IK is often regarded as invalid and unreliable to use in forest management and its value has been eroded and replaced with western scientific knowledge for both production and conservation forest management objectives. However, despite the application of modern scientific knowledge, forest status continues to decline. This paper aims to explore IK held by communities in the Zigi catchment in Tanzania and assess the influence of this form of knowledge on forest management. The study used focus group discussions to explore IK related to forest management from communities living adjacent to forest reserves and a checklist questionnaire to assess the level of use of IK in forest management at different levels of decision-making. The results reveal several IK and practices related to forests in this region. However, there is minimal evidence of consideration of this IK in forest management decision- making. This paper recommends that a serious review of IK related to forests is undertaken in Tanzania and that mechanisms are developed to integrate this form of knowledge with western scientific forest management in order develop a more holistic approach to sustainable forest management.

  9. Simulation of the Effect of Intensive Forest Management on Forest Production in Sweden

    Full Text Available The effects of intensifying the management of 15% of the Swedish forest land on potential future forest production over a 100-year period were investigated in a simulation study. The intensive management treatments, which were introduced over a period of 50 years, were: intensive fertilization of Norway spruce (IntFert; bulking-up Norway spruce elite populations using somatic embryogenesis (SE-seedlings; planting of lodgepole pine, hybrid larch, and Sitka spruce (Contorta, Larch, and Sitka; fertilization with wood ash on peatlands (Wood ash; and conventional fertilization in mature forests (ConFert. Potential sites for applying intensive forest management (IFM to sites with low nature conservation values were determined with a nature conservation score (NCS. Four different scenarios were simulated: “Base scenario”, which aimed at reducing the negative impact on nature conservation values, “Fast implementation”, “No IntFert” (IntFert was not used, and “Large Forest Companies”, where the majority of plots were selected on company land. Total yields during the 100-year simulation period were about 85–92% higher for the intensive forest management scenarios than for the reference scenario (business as usual. In the “No IntFert” scenario total production was 1.8% lower and in the “Large Forest Companies” scenario total production was 4.8% lower than in the “Base scenario”. “Fast implementation” of IFM increased yield by 15% compared to the “Base scenario”. Norway spruce SE-seedlings and IntFert gave the highest yields, measured as total production during the 100-year simulation period, but relative to the yields in the reference scenario, the highest increases in yield were for Contorta. The “Base scenario” and “No IntFert” gave the highest yields for plots with the lowest NCS, but plots with higher NCS had to be used in the “Fast implementation” and “Large Forest Companies” scenarios.

    2009-11-01

    Full Text Available The present chaotic transformation from the industrial to the global information society is accelerating the ecological, social and economic unsustainability. The rapidly growing unsustainable, fossil energy powered urbanindustrial technosphere and their detrimental impacts on nature and human well-being are threatening the solar energy powered natural and seminatural biosphere landscapes and their vital ecosystem services. A sustainability revolution is therefore urgently needed, requiring a shift from the „fossil age“ to the „solar age“ of a new world economy, coupled with more sustainable lifestyles and consumption patterns. The sustainable future of viable multifunctional biosphere landscapes of the Mediterranean Region and elsewhere and their biological and cultural richness can only be ensured by a post-industrial symbiosis between nature and human society. For this purpose a mindset shift of scientists and professionals from narrow disciplinarity to transdisciplinarity is necessary, dealing with holistic land use planning and management, in close cooperation with land users and stakeholders. To conserve and restore the rapidly vanishing and degrading Mediterranean uplands and highest biological ecological and cultural landscape ecodiversity, their dynamic homeorhetic flow equilibrium, has to be maintained by continuing or simulating all anthropogenic processes of grazing, browsing by wild and domesticated ungulates. Catastrophic wildfires can be prevented only by active fire and fuel management, converting highly inflammable pine forests and dense shrub thickets into floristically enriched, multi- layered open woodlands and recreation forests.

    Forest ecosystems in the western United States evolved over many millennia in response to disturbances such as wildfires. Land use and management practices have altered these ecosystems, however, including fire regimes in some areas. Forest ecosystems are especially vulnerable to postfire management practices because such practices may influence forest dynamics and aquatic systems for decades to centuries. Thus, there is an increasing need to evaluate the effect of postfire treatments from the perspective of ecosystem recovery. We examined, via the published literature and our collective experience, the ecological effects of some common postfire treatments. Based on this examination, promising postfire restoration measures include retention of large trees, rehabilitation of firelines and roads, and, in some cases, planting of native species. The following practices are generally inconsistent with efforts to restore ecosystem functions after fire: seeding exotic species, livestock grazing, placement of physical structures in and near stream channels, ground-based postfire logging, removal of large trees, and road construction. Practices that adversely affect soil integrity, persistence or recovery of native species, riparian functions, or water quality generally impede ecological recovery after fire. Although research provides a basis for evaluating the efficacy of postfire treatments, there is a continuing need to increase our understanding of the effects of such treatments within the context of societal and ecological goals for forested public lands of the western United States.

    Full Text Available The long-term survival of Andean forest landscapes (AFL and of their capacity to contribute to sustainable development in a context of global change requires integrated adaptation and mitigation responses informed by a thorough understanding of the dynamic and complex interactions between their ecological and social components. This article proposes a research agenda that can help guide AFL research efforts for the next 15 years. The agenda was developed between July 2015 and June 2016 through a series of workshops in Ecuador, Peru, and Switzerland and involved 48 researchers and development experts working on AFL from different disciplinary perspectives. Based on our review of current research and identification of pressing challenges for the conservation and sustainable governance of AFL, we propose a conceptual framework that draws on sustainability sciences and social–ecological systems research, and we identify a set of high-priority research goals and objectives organized into 3 broad categories: systems knowledge, target knowledge, and transformation knowledge. This paper is intended to be a reference for a broad array of actors engaged in policy, research, and implementation in the Andean region. We hope it will trigger collaborative research initiatives for the continued conservation and sustainable governance of AFL.

  6. The Multiple Use of Tropical Forests by Indigenous Peoples in Mexico: a Case of Adaptive Management

    Directory of Open Access Journals (Sweden)

    Víctor M. Toledo

    2003-12-01

    Full Text Available The quest for an appropriate system of management for tropical ecosystems necessitates that ecologists consider the accumulated experiences of indigenous peoples in their long-term management of local resources, a subject of current ethnoecology. This paper provides data and empirical evidence of an indigenous multiple-use strategy (MUS of tropical forest management existing in Mexico, that can be considered a case of adaptive management. This conclusion is based on the observation that some indigenous communities avoid common modernization routes toward specialized, unsustainable, and ecologically disruptive systems of production, and yet probably achieve the most successful tropical forest utilization design, in terms of biodiversity conservation, resilience, and sustainability. This analysis relies on an exhaustive review of the literature and the authors' field research. Apparently, this MUS represents an endogenous reaction of indigenous communities to the intensification of natural resource use, responding to technological, demographic, cultural, and economic changes in the contemporary world. This transforms traditional shifting cultivators into multiple-use strategists. Based on a case study, three main features (biodiversity, resilience, and permanence considered relevant to achieving adaptive and sustainable management of tropical ecosystems are discussed.

    2014-07-01

    This article presents and discusses the main elements for a fundamental policy change for groundwater management in The Netherlands. The study analyzes the status and current use of groundwater, the increasing pressure in The Netherlands and many other countries on the natural soil-water system, the effects on quality and quantity of groundwater and the use of the subsoil. An overview is given of the current national and European regulations regarding groundwater and related policies for e.g. drinking water, soil policies and other interventions in the subsurface. The Dutch National Government is developing a new framework for groundwater management that aims a sustainable use of groundwater not only in environmental, but also in economic and social perspective. This framework for groundwater will benefit the Structure vision on the subsoil. The question is how 'sustainable use' can be a guiding principle in groundwater management, strengthening the relation between groundwater quantity and quality. It is proposed to define a generic National approach for the assessment of new and existing activities with potential effects on groundwater and for groundwater quality assessment. Additionally it is proposed to give local authorities the opportunity to set area-specific objectives on a regional or local scale to adjust for specific societal needs and area-specific characteristics. For setting these objectives it is recommended to use the concept of ecosystem services as a leading principle for defining the groundwater quality and quantity (e.g. for use as source for drinking water, aquifer thermal storage and sustaining terrestrial and aquatic ecosystems).

    2013-12-01

    Microbial communities are integral components of the biogeochemistry, fertility, and structure of forest soils, and land management practices that alter the microbial environment may influence the long-term sustainability and productivity of forestlands. In 1989 the Long-term Soil Productivity (LTSP) program was initiated to address the National Forest Management Act's concerns over possible losses in soil productivity due to soil disturbance from forest management on National Forest lands. The LTSP program is a network of 62 sites across the USA and Canada that employs the same 3X3 replicated (X3) factorial experimental design consisting of three harvest intensities (bole only, whole tree, whole tree + forest floor removal) with three soil compaction intensities (none, intermediate, severe) and plots that were split for herbicide when the experiment was initiated. Our purpose was to determine the impact of forest harvest intensity, soil compaction, and their interaction on soil microbial biomass C and N (SMB-C, -N) and soil total nitrogen (TN) and soil organic carbon (SOC) storage in a Pinus taeda L. forest 15-years post-treatment at the Davy Crockett National Forest LTSP site in eastern Texas, USA. We quantified SMB-C and -N using the chloroform fumigation extraction method, and TN and SOC by dry combustion. Soils are loamy sand and were sampled 5X during 2011-2012. In each split-plot, five samples were obtained between two living P. taeda stems to a depth of 10-cm and pooled in the field. Because soil compaction, harvest by soil compaction interaction, and herbicide had no effect on the measured soil properties, results are based on repeated measures ANOVA using harvest and time. Both SMB-C and -N were impacted by harvest and varied with time, and SMB-C had a harvest by time interaction. Generally, both microbial indices decreased in the order: bole only >whole tree > whole tree + forest floor. Soil TN and SOC were both higher in the bole only treatment compared

Despite considerable attention to the technical possibilities for delivering sewage services in a more integrated and sustainable fashion, shifts in planning and management have been slow. Based on an extensive study of Australian cities, Brown et al (2009) have developed a model with six transitional stages and argue that "while there may be cognitive changes (best practice thinking such as water sustainable urban design), there has not been sufficient normative and regulative change to support new practice." They contrast three historic transition stages with three successive sustainable stages. Unfortunately, the study ends in a rather vague outline of "the Water Sensitive City", with little sign-posts indicating how one might transition to this seemingly utopian last stage. In the present paper, we discuss the normative tensions created between the different actors in this increasingly complex playing field, who represent different and often competing values. We suggest that cities have difficulties transitioning from the old contract to one of the newer ones because the hydro-social contract promised by these new stages create normative tensions not only between the new and the old, but also between what one might call different types of environmentalists: naturalists and pragmatists. The naturalists, who for example are very voiced in several cities along the North American west coast, tend to embrace the perception of Nature described by environmental historians as Untouched Wilderness, where technology is pinpointed as the root of the problems. In contrast, the other side lean more on the idea of modernity, with a more pragmatic approach

    The structure of the floodplain forests of the Middle Ebro River (NE Spain) was examined at patch and landscape scales along a three-step chronosequence defined according to the extent of flow regulation-induced hydrogeomorphic changes, with the ultimate purpose of producing baseline information to guide through management and restoration plans. At patch scale, a total of 6,891 stems within 39 plots were registered for species, diameter and health status. The stem density, size class distribution, canopy dieback and mortality were further compared by means of non-parametric tests. At landscape scale, the temporal evolution of the area occupied by forest stands of different ages in the floodplain along the chronosequence was evaluated using four sets of aerial photographs dated in 1927, 1957, 1981 and 2003. The within-patch structure of pioneer forests (25-30 years old) were characterized by declining and sparse P. nigra- S. alba- Tamarix spp. stands, where late-seral species such as Ulmus minor and Fraxinus angustifolia were frequent, but only as small-size stems. At landscape scale, these type of senescent forests have doubled their surface after river regulation was intensified. Populus alba only appeared in the oldest plots recorded (colonized before 1957), suggesting sexual regeneration failure during the last five decades, but usually as healthy and dense stands. Based on these findings, measures principally aimed at recovering some hydrogeomorphic dynamism are recommended to guarantee the self-sustainability of the floodplain forest ecosystem.

    With the intensification of human activities, preserving animal populations is a contemporary challenge of critical importance. In this context, the umbrella species concept is appealing because preserving a single species should result in the protection of multiple co-occurring species. Practitioners, though, face the task of having to find suitable umbrellas to develop single-species management guidelines. In North America, boreal forests must be managed to facilitate the recovery of the threatened boreal caribou (Rangifer tarandus). Yet, the effect of caribou conservation on co-occurring animal species remains poorly documented. We tested if boreal caribou can constitute an effective umbrella for boreal fauna. Birds, small mammals, and insects were sampled along gradients of post-harvest and post-fire forest succession. Predictive models of occupancy were developed from the responses of 95 species to characteristics of forest stands and their surroundings. We then assessed the similarity of species occupancy expected between simulated harvested landscapes and a 90 000-km2 uncut landscape. Managed landscapes were simulated based on three levels of disturbance, two timber-harvest rotation cycles, and dispersed or aggregated cut-blocks. We found that management guidelines that were more likely to maintain caribou populations should also better preserve animal assemblages. Relative to fragmentation or harvest cycle, we detected a stronger effect of habitat loss on species assemblages. Disturbing 22%, 35%, and 45% of the landscape should result, respectively, in 80%, 60%, and 40% probability for caribou populations to be sustainable; in turn, this should result in regional species assemblages with Jaccard similarity indices of 0.86, 0.79, and 0.74, respectively, relative to the uncut landscape. Our study thus demonstrates the value of single-species management for animal conservation. Our quantitative approach allows for the evaluation of management guidelines prior

    Sustainability Reporting has become a key element in different organisations. Although there have been a number of academic publications discussing the adoption of sustainability reports in the public sector, their numbers have been quite low when compared to those focussing on corporate reports. Additionally, there has been little research on the link between sustainability reporting in Public Sector Organisations (PSOs) and Organisational Change Management for Sustainability (OCMS). This paper focuses on the contribution of sustainability reporting to OCMS. A survey was sent to all PSOs that have published at least one sustainability report based on the GRI guidelines. The study provides a critical analysis of the relation between sustainability reporting and OCMS in PSOs, including the drivers for reporting, the impacts on organisation change management, and the role of stakeholders in the process. Despite still lagging in sustainability reporting journey, PSOs are starting to use sustainability reporting as a communication tool, and this could drive organisational changes for sustainability.

    Flood forests of Acacia kirkii in the Inner Niger Delta, Mali, host large mixed colonies of waterbirds and play a key role in the production of fish fry and the fertilization of surrounding fields. These forests were managed in a sustainable way by local people, until many were destroyed during the drought periods in the 1970s and 1980s. Local populations wish to regenerate these forests, but without outside assistance they fail to do so, due to conflicts of interest.

    Full Text Available Macro-level manmade problems can often be best solved by understanding and manipulating the economics behind it. The world today is facing genuine problems of scarcity of resources and environmental amp ecological issues in view of intergenerational equity. The paper proposes a new approach of identification and classification of i Resources and ii Goods and services in the context of sustainable development. Every economy has ambitious economic growth aspirations which are often found conflicting with the commitments on natural resource conservation and climate change obligations. The proposed methodology is a reconciliation of the aspired economic growth of a region and the conservation of the resources and nature. The paper employs contribution of different types of goods and services in the gross domestic product GDP of a region to analyze sustainability of development. The important parameters that the paper establishes are Sustainability Ratio R Sustainable Growth Rate SG and the Sustainable Development Index SI. These parameters can be used to compare the sustainable development level of different regions. Ensuring natural resource and environmental sustainability will eventually ensure economic sustainability. The paper considers resource depletion concerns as well as the environmental pollutants biological risks carbon footprint warhead proliferation et cetera thereby ensuring all round sustainability from survival to economic end. The sustainability analysis is done for long periods such as 50 years 100 years et cetera. The index shows how sustainable the development of an economy is and how sustainability it is growing. The presently much revered GDP growth numbers are directionless it does not tell the type of growth an economy essentially has. The direction should be sustainability which the paper stresses upon. An illustration of sustainability analysis of India is also done. Such indices can help identifying sustainably developing

    Full Text Available Air transportation industry is a globally growing industry. As an inseparable part of this industry, airport management is also becoming more crucial issue to be dealt with. Airports offer economic and social benefits to the society, but also environmental impacts of airport operations are increasing due to high traffic growth. While airport capacity is increasing, airport operators are being responsible for mitigating environmental constraints. Today to implement airport environmental management system is seen as a critical way of solution. To ensure effective implementation of this system, an organizational change with definite roles, responsibilities and structure are needed. This study illustrates a way of organizational response to market forces and national regulations guiding the achievement of sustainable airports by determining the structure and the roles in an airport organization.

    Full Text Available The construction industry with its nature of project delivery is very fragmented in terms of the various processes that encompass design, construction, facilities and assets management. Facilities managers are in the forefront of delivering sustainable assets management and hence further the venture for mitigation and adaptation to climate change. A questionnaire survey was conducted to establish perceptions, level of commitment and knowledge chasm in practising sustainable facilities management (FM. This has significant implications for sustainable design management, especially in a fragmented industry. The majority of questionnaire respondents indicated the importance of sustainability for their organization. Many of them stated that they reported on sustainability as part of their organization annual reporting with energy efficiency, recycling and waste reduction as the main concern for them. The overwhelming barrier for implementing sound, sustainable FM is the lack of consensual understanding and focus of individuals and organizations about sustainability. There is a knowledge chasm regarding practical information on delivering sustainable FM. Sustainability information asymmetry in design, construction and FM processes render any sustainable design as a sentiment and mere design aspiration. Skills and training provision, traditionally offered separately to designers and facilities managers, needs to be re-evaluated. Sustainability education and training should be developed to provide effective structures and processes to apply sustainability throughout the construction and FM industries coherently and as common practice.

    At the Amazon estuary, the oldest logging frontier in the Amazon, no studies have comprehensively explored the potential long-term population and yield consequences of multiple timber harvests over time. Matrix population modeling is one way to simulate long-term impacts of tree harvests, but this approach has often ignored common impacts of tree harvests including incidental damage, changes in post-harvest demography, shifts in the distribution of merchantable trees, and shifts in stand composition. We designed a matrix-based forest management model that incorporates these harvest-related impacts so resulting simulations reflect forest stand dynamics under repeated timber harvests as well as the realities of local smallholder timber management systems. Using a wide range of values for management criteria (e.g., length of cutting cycle, minimum cut diameter), we projected the long-term population dynamics and yields of hundreds of timber management regimes in the Amazon estuary, where small-scale, unmechanized logging is an important economic activity. These results were then compared to find optimal stand-level and species-specific sustainable timber management (STM) regimes using a set of timber yield and population growth indicators. Prospects for STM in Amazonian tidal floodplain forests are better than for many other tropical forests. However, generally high stock recovery rates between harvests are due to the comparatively high projected mean annualized yields from fast-growing species that effectively counterbalance the projected yield declines from other species. For Amazonian tidal floodplain forests, national management guidelines provide neither the highest yields nor the highest sustained population growth for species under management. Our research shows that management guidelines specific to a region's ecological settings can be further refined to consider differences in species demographic responses to repeated harvests. In principle, such fine

Conservation of tropical trees can be achieved if supported by the sustainable use of forest by community live nearby through harvesting of non timber woods, for instance rattan. Furthermore, rattan jernang individuals and trees have significant associations. Therefore, objective of this paper is to investigate the utilization of rattan jernang (Deamonorops draco Wild related to the forest tree biodiversity by Anak Dalam tribe in several villages in Jambi, Sumatra. The study has identified that populations of Deamonorops draco were varied among villages, ranged from 40 to 71 clumps in the forests and up to 500 clumps in plantations. Moreover, 73 individual trees consisted of 32 species were identified as rattan host and conserved by the community. Dialium platyespalyum. Quercus elmeri, and Adinandra dumosa were rattan host trees with the highest populations. Meanwhile, a biodiversity of non-host trees consisted of 30 individual trees from 16 species. Interviews revealed that traditional harvesters have acknowledged that trees have significant important ecological roles for the rattan livelihood and therefore it is very important to conserve the forests for the sustainability of harvest in the future. Furthermore, to secure the availability of rattan, the traditional harvesters had started rattan plantation.

  15. Soil management: The key to soil quality and sustainable agriculture

    Today, after the International Year of Soils in 2015 and the proclamation by the International Union of Soil Sciences of the International Decade of Soils 2015-2020, much attention is paid to soil quality. Often used interchangeably, both terms, soil quality and soil health, refer to dynamic soil properties such as soil organic matter or pH, while soil quality also includes inherent soil properties such as texture or mineral composition. However, it is the dynamic or manageable properties that adequate soil management can influence and thus contribute to a well-functioning soil environment capable to deliver the soil-mediated provisioning, regulating and supporting ecosystem services and soil functions. This contribution intends to highlight the key principles of sustainable soil management and provide evidence that they are compliant with a productive, resource efficient and ecologically friendly agriculture. Paradoxically, and despite benefitting from good soil quality, agriculture itself when based on conventional, especially intensive tillage-based soil management practices contributes decisively to soil degradation and to several of the soil threats as identified by the Soil Thematic Strategy, being soil erosion and soil organic matter decline the most notorious ones. To mitigate soil degradation, the European Union's Common Agricultural Policy has introduced conservation measures, mainly through cross-compliance measures supposed to guarantee minimum soil cover, to limit soil erosion and to maintain the levels of soil organic matter. However, it remains unclear to what extent EU member states apply these 'Good Agricultural and Environmental Condition' (GAEC) measures to their utilized agricultural areas. Effective and cost-efficient soil management systems able to conserve or to restore favourable soil conditions, to minimize soil erosion and to invert soil organic matter and soil biodiversity decline and improve soil structure are those capable to mimic as

    Directory of Open Access Journals (Sweden)

    Jilske O. de Bruin

    2015-09-01

    Full Text Available Challenges of contemporary forest management are frequently referred to as complex. This article empirically studies complexity in forest management decision-making. In contrast to what is often assumed in the literature, this article starts by assuming that complexity does not just consist of an external descriptive element, but also depends on how decision-makers perceive the system at hand. This “perceived complexity” determines decision-making. We used a straightforward interpretation of perceived complexity using two criteria: the number of factors considered and the uncertainty perceived about these factors. The results show that Dutch forest managers generally consider forest management decision-making to be complicated (many factors to consider rather than complex (many uncertain factors to consider. Differences in sources of complexity confirm the individual character of perceived complexity. The factors perceived to be most relevant for decision-making (the forest itself, the organization’s objective, the cost of management, public opinion, national policies and laws, and new scientific insights and ideas are generally seen as rather certain, although “complexity reduction” may play a role that can adversely affect the quality of decision-making. Additional use of more open-ended, forward-looking methods, such as qualitative foresight tools, might enable addressing uncertainty and complexity, and thereby enhance decision-making in forest management to prepare for increasing complexity in the future.

  19. Can We Use Forest Inventory Mapping as a Coarse Filter in Ecosystem Based Management in the Black Spruce Boreal Forest?

    Directory of Open Access Journals (Sweden)

    Chafi Chaieb

    2015-04-01

    Full Text Available Forest inventory mapping is used worldwide to describe forests at a large spatial scale via the delimitation of portions of the landscape that are structurally homogeneous. Consequently, there is a significant amount of descriptive forest data in forest inventory maps, particularly with the development of ecosystem classification, which represents a significant potential for use in ecosystem based management. With this study we propose to test whether forest inventory maps can be used to describe not only stand characteristics but also dynamic processes. The results indicate that stand types identifiable in forest inventory maps do not in fact represent unique developmental stages, but rather confound stands at multiple developmental stages that may be undergoing different ecological processes. The reasons for this are linked to both the interaction between succession, fire severity and paludification. Finally, some aspects of the process of forest inventory mapping itself contribute to the disjunction between forest types and forest succession. Given the low similarity between spruce mapping types and their actual description following forest inventories, it would be too ambitious to infer the dynamic aspects of spruce forest by map units.

    Due to their biodiversity, forests generate a range of products and services that are of economic, social or cultural value to human beings. Natural resource management provisions should ensure the creation and maintenance of these goods and services in the long term. However, unsustainable management practices of forests do not only generate short-term benefits but also considerable costs for society. Payment by the beneficiaries of the services would enable us to internalise external costs ...

  7. Clarifying the Imperative of Integration Research for Sustainable Environmental Management

    2005-01-01

    Full Text Available This paper discusses why integration is important in doing research for developing policy and practice of sustainable environmental management. The imperative of integration includes environmental, social, economic, and other disciplinary considerations, as well as stakeholder interests. However, what is meant by integration is not always clear. While the imperative is being increasingly enunciated, the challenges it presents are difficult and indicate a long term pursuit. This paper clarifies the different dimensions of integration, as an important preliminary step toward advancing mutual understanding and the development of approaches. The paper identifies the driving forces for integration, discusses when integration is required, categorises forms of integration, and proposes principles to inform research programs and projects.

    Large area of the Hindu Kush Himalayan (HKH) region is covered by forest that is playing a vital role to address the challenges of climate change and livelihood options for a growing population. Effective management of forest cover needs establishment of regular monitoring system for forest. Supporting REDD assessment needs reliable baseline assessment of forest biomass and its monitoring at multiple scale. Adaptation of forest to climate change needs understanding vulnerability of forests and dependence of local communities on these forest. We present here different forest monitoring products developed under the SERVIR-Himalaya programme to address these issues. Landsat 30 meter images were used for decadal land cover change assessment and annual forest change hotspot monitoring. Methodology developed for biomass estimation at national and sub-national level biomass estimation. Decision support system was developed for analysis of forest vulnerability and dependence and selection of adaptation options based on resource availability. These products are forming the basis for development of an integrated system that will be very useful for comprehensive forest monitoring and long term strategy development for sustainable forest management.

    2010-01-01

    Participatory approaches to natural resource management and development are widely accepted as effective instruments for achieving sustainable forest management (SFM) particularly in the developing countries. However, local people live within and adjacent to the forest resources and are dependent on the forest in terms of their livelihoods may prevent turning some decisions, intended as a component of sustainable forest management, into action. This situation arises from the lack of involvement by local stakeholders, a condition that is generally accepted as one of the most important instruments of sustainable forest management. Consequently forest and other natural resources have not been effectively protected from negative behaviours of local populations. In this study difficulties that have been faced in acquiring local participation and the importance of local participation for sustainable forest management are discussed using two case studies from Turkey. At acquiring of local participation is considered to important of local perceptions. If perceptions are negative, participation will not obtain. Thus, the study has focused on local perceptions. Field survey was carried out to collect necessary information for each case study. We conclude that decisions that will restrict the natural resource benefits for the local public, will lead to negative local perceptions of the project and lead to adverse behavior and negatively affect sustainable forest management efforts.

    2013-10-01

    Lichens are an important component of the boreal forest, where they are long lived, tend to accumulate in older stands, and are a major food source for the threatened woodland caribou (Rangifer tarandus caribou). To be fully sustainable, silvicultural practices in the boreal forest must include the conservation of ecological integrity. Dominant forest management practices, however, have short-term negative effects on lichen diversity, particularly the application of herbicides. To better understand the long-term effects of forest management, we examined lichen regeneration in 35 mixed black spruce (Picea mariana) and jack pine (Pinus banksiana) forest stands across northern Ontario to determine recovery following logging and postharvest silvicultural practices. Our forest stands were 25-40 years old and had undergone 3 common sivilcultural treatments that included harvested and planted; harvested, planted, and treated with N-[phosphonomethyl] glycine (glyphosate); and harvested, planted, and treated with 2,4-dichlorophenoxyacetic acid (2,4-D). Forest stands with herbicide treatments had lower lichen biomass and higher beta and gamma diversity than planted stands that were not treated chemically or control stands. In northwestern Ontario, planted stands that were not treated chemically had significantly greater (p < 0.05) alpha diversity than stands treated with herbicides or control stands. Our results show that common silvicultural practices do not emulate natural disturbances caused by wildfires in the boreal forest for the lichen community. We suggest a reduction in the amount of chemical application be considered in areas where lichen biomass is likely to be high and where the recovery of woodland caribou is an objective. © 2013 Society for Conservation Biology.

  19. The Use of Traditional Ecological Knowledge in Forest Management: an Example from India

    Directory of Open Access Journals (Sweden)

    Lucy Rist

    2010-03-01

    Full Text Available Many forest communities possess considerable knowledge of the natural resources they use. Such knowledge can potentially inform scientific approaches to management, either as a source of baseline data to fill information gaps that cannot otherwise be addressed or to provide alternative management approaches from which scientists and managers might learn. In general, however, little attention has been given to the relevance of quantitative forms of such knowledge for resource management. Much discussion has focused on the integration of traditional ecological knowledge (TEK into management, but less attention has been paid to identifying specific areas where it is most useful and where it may be most problematic. We contrasted scientific data with information from TEK in the context of a threat to the sustainable harvesting of a nontimber forest product (NTFP of livelihood importance in southern India, specifically, a fruit tree infected by mistletoe. The efficiency of deriving information from NTFP harvesters compared to scientific field studies was assessed. We further evaluated the potential of TEK to provide novel solutions to the management problem in question, the degree to which TEK could provide quantitative information, and the biases that might be associated with information derived from TEK. TEK complemented previously gathered ecological data by providing concordant and additional information, but also contradicted some results obtained using a scientific approach. TEK also gave a longer-term perspective with regard to NTFP harvesting patterns. Combining information on historical and current harvesting trends for the NTFP with official data suggests that current assessments of sustainability may be inaccurate and that the use of diverse information sources may provide an effective approach to assessing the status of harvested resources.

    Disturbances in Canada's boreal forest occur in both upland forests and in peatlands. These disturbances originate from both anthropogenic and natural causes, particularly fire. Techniques for the restoration, as well as the reclamation of peatlands and forests impacted by agriculture, urban development, or oil and gas activities, have made significant advancement over the last decade and these techniques need to be incorporated into the regulation and management of peatland and forest ecosystems. This symposium addressed the issue of how this research is affected by climate change. The sessions were entitled: (1) reclaiming forest and forest soils impacted by oil and gas production, (2) influence of oil sands development on forest communities, (3) understanding the importance of peatland and forest carbon in the twenty-first century, (4) reclaiming wetlands on mined oil sands tailing, (5) disturbance in peatlands and its relevance to minimizing disturbance footprints and informing reclamation efforts, and (6) restoration and management of harvested peatlands. The symposium featured 37 presentations, of which 6 have been catalogued separately for inclusion in this database. refs., tabs., figs.

    2017-04-01

    In the cross-border belt between Serbia and Montenegro are located more than one hundred torrential water flows that belong to the Lim River Basin. Under extreme climate events they turned into floods of destructive power and great energy causing enormous damage on the environment and socio-economic development in the wider region of the Western Balkans. In addition, anthropogenic factors influence the land instability, erosion of river beds and loss of topsoil. Consequently, this whole area is affected by pluvial and fluvial erosion of various types and intensity. Terrain on the slopes over 5% is affected by intensive degree of erosion, while strong to medium degree covers 70% of the area. Moreover, in the Lim River Basin were built several hydro-energetic systems and accumulations which may to a certain extent successfully regulate the water regime downstream and to reduce the negative impact on the processes of water erosion. However, siltation of accumulation reduces their useful volume and threatens the basic functions (water reservoirs), especially those ones for water supply, irrigation and energy production that have lost a significant part of the usable volume due to accumulated sediments. Facing the negative impacts of climate change and human activities on the process of land degradation in the Lim River basin imposes urgent need of adequate preventive and protective measures at the local and regional level, which can be effectively applied only through enhanced cross-border cooperation among affected communities in the region. The following set of activities were analyzed to improve the actual management of river catchment: Identifying priorities in the spatial planning, land use and water resources management while respecting the needs of local people and the communities in the cross border region; development of cooperation and partnership between the local population, owners and users of real estate (pastures, agricultural land, forests, fisheries

    Tikal has long been viewed as one of the leading polities of the ancient Maya realm, yet how the city was able to maintain its substantial population in the midst of a tropical forest environment has been a topic of unresolved debate among researchers for decades. We present ecological, paleoethnobotanical, hydraulic, remote sensing, edaphic, and isotopic evidence that reveals how the Late Classic Maya at Tikal practiced intensive forms of agriculture (including irrigation, terrace construction, arboriculture, household gardens, and short fallow swidden) coupled with carefully controlled agroforestry and a complex system of water retention and redistribution. Empirical evidence is presented to demonstrate that this assiduously managed anthropogenic ecosystem of the Classic period Maya was a landscape optimized in a way that provided sustenance to a relatively large population in a preindustrial, low-density urban community. This landscape productivity optimization, however, came with a heavy cost of reduced environmental resiliency and a complete reliance on consistent annual rainfall. Recent speleothem data collected from regional caves showed that persistent episodes of unusually low rainfall were prevalent in the mid-9th century A.D., a time period that coincides strikingly with the abandonment of Tikal and the erection of its last dated monument in A.D. 869. The intensified resource management strategy used at Tikal-already operating at the landscape's carrying capacity-ceased to provide adequate food, fuel, and drinking water for the Late Classic populace in the face of extended periods of drought. As a result, social disorder and abandonment ensued.

    Science.gov (United States)

    Tappeiner, John; Poage, Nathan; Erickson, Janet L.

    2003-01-01

    Background As part of the Northwest Forest Plan, large areas have been designated on many federal forests in western Oregon to provide critical habitat for plants and animals that are associated with old-growth habitat. Some of the structural characteristics often considered typical of old forests include large-diameter overstory trees, large standing and fallen dead trees, and one or more understory layers (Figure 1). However, not all of these areas are currently in old-growth conditions. Many of them contain young (regenerated after timber harvest. The original management goal for these stands was to produce high yields of timber and associated wood products. With implementation of the Northwest Forest Plan in 1994, the management objective shifted to accelerating development of old-growth characteristics by enhancing structural and biological diversity of these areas. A major challenge today is how to promote these structural characteristics in younger stands. Researchers have been asking if lessons can be learned from the development of our current old growth and applied to management of younger stands. Dr. John Tappeiner and his university and agency research partners are helping to answer this question by examining the differences in development between old-growth and young stands in western Oregon. Understanding how the structure of these old forests developed may provide a model for management of young stands, especially when the management goal is to provide habitat for species associated with older forests.

  15. Managing climate change in conservation practice: an exploration of the science-management interface in beech forest management.

    de Koning, Jessica; Turnhout, Esther; Winkel, Georg; Blondet, Marieke; Borras, Lars; Ferranti, Francesca; Geitzenauer, Maria; Sotirov, Metodi; Jump, Alistair

    Scientific studies reveal significant consequences of climate change for nature, from ecosystems to individual species. Such studies are important factors in policy decisions on forest conservation and management in Europe. However, while research has shown that climate change research start to impact on European conservation policies like Natura 2000, climate change information has yet to translate into management practices. This article contributes to the on-going debates about science-society relations and knowledge utilization by exploring and analysing the interface between scientific knowledge and forest management practice. We focus specifically on climate change debates in conservation policy and on how managers of forest areas in Europe perceive and use climate change ecology. Our findings show that forest managers do not necessarily deny the potential importance of climate change for their management practices, at least in the future, but have reservations about the current usefulness of available knowledge for their own areas and circumstances. This suggests that the science-management interface is not as politicized as current policy debates about climate change and that the use of climate change ecology is situated in practice. We conclude the article by discussing what forms of knowledge may enable responsible and future oriented management in practice focusing specifically on the role of reflexive experimentation and monitoring.

    2016-12-01

    Full Text Available Making decisions in a dynamic environment requires from managers to operate with modern perfor-mance measurement tools. Having a development strategy becomes insufficient. It is important to make use of operational and strategic management accounting, developing on many levels. One of its tools is balanced scorecard, developed by R. Kaplan and D. Norton. It is a method of complex, multi-faceted performance measurement in the enterprise. It is a useful tool for describing, implementation and execu-tion of the company’s strategy. In order to develop a balanced scorecard it is necessary to create a clear mission and vision and a coherent framework for organization strategy. State Forests as a specific entity also needs efficient and effective management tools. In its strategy for the years 2014–2030 State Forests included the basic principles and measures of a balanced scorecard, which, like every tool, requires contin-uous monitoring and improvement.The aim of the article is to present proposals for modification of the existing concept of State Forests’ balanced scorecard, which will improve the usefulness of the information. The issue has been discussed in the context of pro-social activities of State Forests, in the conditions of globalization and sustainable de-velopment. The main research method used in the article in addition to literature studies is qualitative re-search based on case study.

    The scale of land-contamination problems, and of the responses to them, makes achieving sustainability in contaminated land remediation an important objective. The Sustainable Remediation Forum in the UK (SuRF-UK) was established in 2007 to support more sustainable remediation practice in the UK. The current international interest in 'sustainable remediation' has achieved a fairly rapid consensus on concepts, descriptions and definitions for sustainable remediation, which are now being incorporated into an ISO standard. However the sustainability assessment methods being used remain diverse with a range of (mainly) semi-quantitative and quantitative approaches and tools developed, or in development. Sustainability assessment is site specific and subjective. It depends on the inclusion of a wide range of considerations across different stakeholder perspectives. Taking a tiered approach to sustainability assessment offers important advantages, starting from a qualitative assessment and moving through to semi-quantitative and quantitative assessments on an 'as required' basis only. It is also clear that there are a number of 'easy wins' that could improve performance against sustainability criteria right across the site management process. SuRF-UK has provided a checklist of 'sustainable management practices' that describes some of these. This paper provides the rationale for, and an outline of, and recently published SuRF-UK guidance on preparing for and framing sustainability assessments; carrying out qualitative sustainability assessment; and simple good management practices to improve sustainability across contaminated land management activities.

    The projected change in global climate may have various impacts on forest ecosystems. Changes in the growth of different forest species will also influence the competitive relationships between species, the potential species composition in unmanaged forest and the choice of species in managed forests. While impacts of climate change on physiological processes and the potential natural species composition in forests have been intensively investigated in the last few years, there has been hardly any research on possible consequences in managed forests.

  4. Potential of forest management to reduce French carbon emissions - regional modelling of the French forest carbon balance from the forest to the wood.

    In France the low levels of forest harvest (40 Mm3 per year over a volume increment of 89Mm3) is frequently cited to push for a more intensive management of the forest that would help reducing CO2 emissions. This reasoning overlooks the medium-to-long-term effects on the carbon uptake at the national scale that result from changes in the forest's structure and delayed emissions from products decay and bioenergy burning, both determinant for the overall C fluxes between the biosphere and the atmosphere. To address the impacts of an increase in harvest removal on biosphere-atmosphere carbon fluxes at national scale, we build a consistent regional modeling framework to integrate the forest-carbon system from photosynthesis to wood uses. We aim at bridging the gap between regional ecosystem modeling and land managers' considerations, to assess the synergistic and antagonistic effects of management strategies over C-based forest services: C-sequestration, energy and material provision, fossil fuel substitution. For this, we built on inventory data to develop a spatial forest growth simulator and design a novel method for diagnosing the current level of management based on stand characteristics (density, quadratic mean diameter or exploitability). The growth and harvest simulated are then processed with a life cycle analysis to account for wood transformation and uses. Three scenarii describe increases in biomass removals either driven by energy production target (set based on national prospective with a lock on minimum harvest diameters) or by changes in management practices (shorter or longer rotations, management of currently unmanaged forests) to be compared with business as usual simulations. Our management levels' diagnostics quantifies undermanagement at national scale and evidences the large weight of ownership-based undermanagement with an average of 26% of the national forest (between 10% and 40% per species) and thus represents a huge potential wood resource

    Forest biomass is a promising feedstock for the production of bioenergy, biofuels, and bioproducts because it is renewable and widely available as a byproduct of forest management. Its harvest and use also has the potential to positively impact rural communities, especially those negatively impacted by upheaval in the forest sector.

    To facilitate forest planning and management on National Wildlife Refuges, we synthesized multiple data sources to describe land ownership patterns, land cover, landscape pattern, and changes in forest composition for four ecoregions and their associated refuges of the Upper Midwest. We related observed patterns to ecological processes important for forest conservation and restoration, with specific attention to refuge patterns of importance for forest landbirds of conservation priority. The large amount of public land within the ecoregions (31-80%) suggests that opportunities exist for coarse and meso-scale approaches to conserving and restoring ecological processes affecting the refuges, particularly historical fire regimes. Forests dominate both ecoregions and refuges, but refuge forest patches are generally larger and more aggregated than in associated ecoregions. Broadleaf taxa have increased in dominance in the ecoregions and displaced fire-dependent taxa such as pine ( Pinus spp.) and other coniferous species; these changes in forest composition have likely also affected refuge forests. Despite compositional changes, larger forest patches on refuges suggests that they may provide better habitat for area-sensitive forest landbirds of mature, compositionally diverse forests than surrounding lands if management continues to promote increased patch size. We reason that although fine-scale research and monitoring for species of conservation priority is important, broad scale (ecoregional) assessments provide crucial context for effective forest and wildlife management in protected areas.

  12. Examining farm forest owners' forest management in Ireland: the role of economic, lifestyle and multifunctional ownership objectives.

    2013-07-15

    Using a nationally representative survey of 263 farm operators in Ireland, this study develops a typology of private forest landowners' objectives for forest ownership. It is important to understand farmers' forest ownership objectives as this will enhance economic analysis in general, but also to formulate more effective policies that take into account the range of motivational profiles of landowners. Using principal component analysis, three core motivations for forest ownership are identified representing economic, lifestyle and multifunctional benefits. Using a binary logistic regression model these ownership objectives were found to have a significant impact on farmers' forest management. For instance, farmers with relatively stronger economic motivations for forest ownership were found to be much more likely to harvest thinnings whereas the opposite was true of those with more lifestyle orientated objectives. In order to tailor policy at groups with different forest ownership objectives it will be important to be able to identify them through more easily observable owner and property characteristics. This study through multivariate regression analysis found factors such as age of the farm operator, land quality, system of farming, off farm employment and environmental attitudes were related to farm forest owners' ownership objectives. The study concludes that a better understanding of the heterogeneity in farmers' forest ownership objectives will enable policymakers to tailor incentives that more closely align with the diverse motivational profiles of different groups of landholders.
