Resumen

The paper presents the methodology of virtual stand generation. Virtual stand serves for forestry e-learning as a tool for training of forest tending and demonstration of stand structure and some forest mensuration practices. The model can be connected with growth simulator and geographical information system, or integrated into the Internet environment. In the first part of the paper, the methodology of individual tree visualisation, total stand visualisation, terrain and stand environment visualisation and the principle of user’s interaction with virtual forest are proposed. The Virtual Reality Model Language (VRML 97) was used for these goals. In the second part of the paper, an example of model usage for the training of forest tending is presented.

Resumen

AbstractAid donors, civil society groups and the Cambodian government have tended to focus their policy initiatives concerned with communities and their forests on Cambodia's indigenous minorities. Few attempts have been made to document the relationship between ethnic Khmers and forests. However, with almost three quarters of Cambodia covered with forests until quite recently, and a large proportion of the Khmer population living in proximity to forests, it is not surprising that Cambodia's dominant ethnic group has had a close and meaningful relationship with forests. In this article, we examine the traditional systems of forest management of Khmer social groups and how these systems are changing. We argue that traditional Khmer systems of forest management are still relevant in the context of the rapid changes that have occurred in rural Cambodia over the past two decades. These systems shape how Khmer groups make sense of the natural world and claim rights of tenure over forest areas. They continue to play a vital role in preserving Cambodia's natural forests in the face of deforestation driven by plantation schemes and logging operations.

Resumen

The article is dedicated to forest systems management in Russia in conditions of increasing discrepancy between decreasing forest areas, degradation of their state and steady growth of need for different functions of forests. Inadequacy of managerial solutions is determined by a variety of problems, among which is lack of systems analysis of the problem of extremely intensive and disorganized timber logging in conditions of inefficient reproduction of trees and low productivity of forests. To switch to sustainable forest management a methodology of sequential analysis of maintenance and reproduction of forest systems has been developed. Complexity growth of highly sophisticated forest systems management, which is characterized by hierarchy and emergence, requires the use of systems analyses of certain subsystems within the structure of forest system at the level of their interaction and relations among them. The forest system structure is represented in the form of large subsystems according to their main objectives: creation of highly efficient and cost effective timber stand, conservation of biological diversity and useful features of forest systems, maintenance of social and economic functions of forests. For overall evaluation of forest systems management, efficiency criteria and indices targeted at final result have been used. At the practical level, these criteria reflect the required changes in the forest system on the whole in simplified form and serve as baseline for intensive techniques of forest systems management. Forests reproduction is determined by a large quantity of natural and anthropogenic factors, among which preparation of soil, quality of seeds, production and planting of seedlings, crop cultivation, felling etc. Each factor should also be considered as a subsystem with corresponding elements and relations among them. For opportune adoption of measures, efficiency evaluation of appropriate activities in the processes of constant dynamics of forest areas is necessary, which allows us to create information basis for predicting short-term and long-term forests reproduction. The influence of each factor can be estimated using orgraphs technique, where the nodes of the graph are the studied indices and the arcs reflect intensity of influence change of one index on the other. A variety of models reflecting the essence and process conditions of the forest system will serve as baseline for building a mathematical model with subsequent switch to digital models.

Resumen

The total area of the forest fund of Ukraine is 10400000 hectares, of which 9600000 hectares are covered with forest vegetation. In total, 15.9 % of the country's area is covered by forests. This figure is growing: in 50 years the area of forests increased by 21 %, almost three times increased stock of wood – it is estimated within 2102 million cubic meters. But this is not enough. Today there are a number of problems connected with forestry, for example: mass destruction of forests, lack of forest development strategy, low level of forest resources use, lack of reliable information about the biomass condition, forest fires. According to the State Agency of Forest Resources of Ukraine, the volume of unauthorized felling has been steadily decreasing for a long time, during 2005-2010. However, already in 2011 it was 25,100 cubic meters, which is 2.2 thousand more than in the previous year, 2007. However, this statistic, too, is mostly about illegal logging by local people, so it reflects very small volumes. The largest number of poached logging is recorded in the Lviv region. For example, in 2018 in the region 12,047 cubic meters of wood were illegally cut, and the figures do not stand still. As a consequence, this situation over time can lead to environmental degradation, increased water and wind erosion, degradation of agricultural land. The forest industry is one of the promising industries in Ukraine, for which it is advisable to use the tools of geographic information systems that provide detailed and necessary information, which greatly simplifies the work in research, analysis and prediction of the dynamics of the forestry fund of Ukraine. With the help of geospatial analysis tools we open up new horizons in the development and organization of forestry production, control and management of forests at all levels. This is why in today's conditions the introduction of geoinformation technologies can not only save money, but also save large areas of the forest fund and hundreds of diligent villages, settlements and cities. The events that took place in April 2020 showed that the lack of active monitoring of burning areas has painful consequences. The fire destroyed almost 40 houses in the resettled villages, Lichmans Srednyaya Rudnya, Nizhnyaya Rudnya and Verkhnyaya Rudnya, 45 buildings were saved, about 5 % of the protected area, 11500 hectares in the southwestern part of the Chernobyl Reserve were affected. These villages in Zhytomyr region were resettled after Chernobyl. More than 2000 people and 120 units of equipment were involved in extinguishing the fireі.

Resumen

SUMMARYIn developing countries, the landscape surrounding agricultural land is important for maintaining biodiversity and providing ecosystem services. Forests provide a full suite of goods and services to subsistence farmers in the Himalayan agro-ecological system. The effects of biomass outtake on woody species richness and composition were analysed in forests under communal and government management. Interviews on forest use and perception of forest condition and ecosystem service delivery were conducted in farmer households bordering the forests. Significantly more woody species were found in the community managed forests. Species richness was negatively correlated with walking distance from the nearest village and increasing levels of anthropogenic disturbance. Community forests were generally less degraded than government managed forests, giving support to common pool resource management. Woody vegetation represented a crucial source of fuelwood, timber, fodder, and edible, aromatic and medicinal plants. Using a multidisciplinary framework to analyse ecosystem integrity and ecosystem service delivery enabled a finer understanding of these complex agro-ecological systems, giving support to evidence-based management and conservation planning for the future.

Resumen

To clarify how different forest management systems affect the diversity of understory vascular plant species at the plot level and the forest-type level, we examined a forested landscape originally occupied by primary Japanese beech, Fagus crenata Blume, in central Japan. The landscape is currently composed of four types of forest: primary F. crenata forest, shelterwood logged F. crenata forest, abandoned coppice forest, and coniferous plantation. Species richness per plot (α diversity) and in each forest type (γ diversity) and species turnover among plots in each forest type (β diversity) reached their highest values in plantation forests. While the difference in species composition between primary and shelterwood logged forests was not significant, the other pairs of forest types showed significant differences. Ordination analysis revealed that variation in species composition within the plantations seemed to be related to the dominance of naturally regenerated tree species, which reflected the intensity of tending. Although the species composition of less intensively tended plantations was similar to that of abandoned coppice forests that had been repeatedly cut in the past, their species composition differed from that of the primary forests. This suggests that most of the plantation and coppice forests, which were clear-cut at least once, do not revert to primary forest conditions after management is abandoned.

Resumen

Research on forest management in North America has traditionally focussed on large, industrial forest tenures (involving both public and private land), or small, private woodlot management. Recent discussion and experiments in Canada involve new institutions for forest management. These alternative forest management systems — namely, co-managed forests and community forests — are compared to traditional forest management along several dimensions, including: locus of decision-making, nature of decision-making, scope of decision-making, tenure structure, scale, and knowledge base. There exists a gap between abstract discussions and practical applications of these models. Prospects for the continued development of these alternative management systems are evaluated. Key words: co-management, community forestry, decision making, forest tenure, forest management objectives

Resumen

This dissertation adopts the perspective of Cognitive Ethnography to examine the work of a grassroots, Navajo environmental organization called Diné Citizens Against Ruining our Environment. Specifically, I will examine the work and the challenges facing the members of this organization in order to evaluate how new communications and information technologies may be of use to them. This analysis begins, as Cognitive Ethnography mandates, with a general description of the tasks which constitute the work of Diné CARE. As will be discussed, these consist primarily in attempts to reassert what the organization's members consider to be traditional Navajo perspectives on economic development and the human relationship with the natural environment. Subsequently, I analyze the representations, measurements of work, and forms of organization required to accomplish Diné CARE's tasks. In all aspects of the work, members were constantly required to manage a dialogue between their preferred means of organizing or representing work, and the means required by the operating environment in which they found themselves, characterized primarily by relationships with various outside sources of legal, technical or financial support. The work of Diné CARE is thus extensively "dialogic." While members continually drew on Navajo traditions for viewing the relationship of human beings to the natural environment, for representing their work, and for building cooperative access to resources for resistance, they were nonetheless required at the same time to position these "traditional" approaches against approaches whose history of development have political, social and cultural roots in Western Europe and modem America. Often, this dialogue brought with it tension and even morally charged conflict for the members of Diné CARE. This tension extended to emerging technologies as well. In spite of many claims to the contrary, new communications and information technologies did little to alleviate the mismatch between "local" and "foreign" ways of doing work. Instead of "empowering" local communities by providing them access to information or the chance to be heard on their own terms, new technologies complicated the scenario of local resistance by requiring practices for representing work which were both difficult to master and often inappropriate.

Dissertation (PhD (For))--University of Stellenbosch, 2001.
ENGLISH ABSTRACT: The objective of this study is to develop a new method which can be used to forecast the Forest Engineering value chain. The method is then applied in the South African context in order to validate the use thereof. Finally, the South African results are used to propose strategies, which the industry should pursue in the future. To forecast the future an understanding of the past is required. To this end, the historical development of Forest Engineering is discussed, both globally and in South Africa. The current status quo in Forest Engineering in South Africa was determined through a national survey of plantations larger than 200 ha. The results are reflected in Chapter 2. Because of the importance of globalisation and technology, Chapter 3 gives a literature review of relevance of technology in today's business world, including various forecasting techniques that are relevant to the study. These techniques are a combination of traditional forecasting methods, technology forecasting methods and strategic planning methods. Various approaches to financial analysis have also been discussed, in order to determine the soundest method of comparing various forest engineering systems with each other. This includes an overview of traditional machine cost calculations. The core of the study lies in the combination of these methodologies into a useful method, which is particularly suited to forecasting the Forest Engineering value chain. Such a method is developed in Chapter 4, based on the literature review of forecasting methodologies. The method is then validated in Chapter 5, through the application thereof in the South African forestry industry. Global trends are established with the use of a Delphi study. This technique uses a panel of experts who give their views on future developments on a multiple round basis. The study then evaluates 14 Forest Engineering systems for pine sawtimber, pine pulpwood and Eucalyptus pulpwood, based on various scenarios of the future. The scenario matrix is based on the future cost of labour vs. the future cost of machinery. Finally, a strategy is proposed on how the South African forestry industry should prepare itself for the future.
AFRIKAANSE OPSOMMING: Die doelwit van die studie is om 'n nuwe metode te ontwikkel waarmee 'n vooruitskatting van die Bosingenieurswese waardeketting gemaak kan word. Die metode word dan in die Suid-Afrikaanse konteks toegepas om die geldigheid daarvan te beproef. Die Suid-Afrikaanse resultate word voorts gebruik om 'n nasionale Bosingenieurswese strategie voor te stel vir die bedryf. Dit is nodig om die verlede te verstaan, voor die toekoms vooruitgeskat kan word. Om dié rede is die historiese ontwikkeling van bosingenieurswese bespreek, in beide 'n internasionale, sowel as 'n Suid Afrikaanse konteks. Die huidige status quo van Bosingenieurswese in Suid Afrika is vasgestel deur 'n nasionale opname waarby plantasies van groter as 200 ha ingesluit is. Die resultate van die opname word weergegee in Hoofstuk 2. As gevolg van die belangrikheid van beide globalisering en tegnologie, is 'n literatuur studie ingesluit in Hoofstuk 3 oor die relevansie van tegnologie in die besigheidswêreld van vandag, asook en 'n bespreking van verskeie vooruitskattingstegnieke wat in die studie gebruik kan word. Hierdie vooruitskattinge is 'n kombinasie van tradisionele vooruitskattings tegnieke, tegnologie vooruitskattingstegnieke en tegnieke wat gebruik word vir strategiese beplanning. Verskeie benaderinge tot finansiële analise is ook bespreek. Dit sluit tradisionele masjienkoste berekening in. Die rede hiervoor is om vas te stel watter metode die mees geskikte sou wees om verskeie Bosingenieurswese sisteme met mekaar te vergelyk. Die kern van die studie lê in die kombinasie van hierdie metodes om 'n bruikbare metode te ontwerp om die Bosingenieurswese waardeketting vooruit te skat. Hierdie ontwerp word in Hoofstuk 4 bespreek. Die metode word in Hoofstuk 5 beproef, deur die toepassing daarvan op die Suid Afrikaanse bosbedryf. Internasionale bosingenieurswese tendense is vasgestel deur middel van 'n Delphi studie. Hierdie vooruitskatting maak gebruik van 'n paneel van kundiges wat hulle siening oor die toekoms uitspreek deur verskeie rondtes van vrae wat aan hulle gestel word. Die studie evalueer hierna 14 Bosingenieurswese sisteme vir denne saaghout, denne pulphout en Eucalyptus pulphout, gebaseer op 'n scenario-analise van die toekoms. Die scenario matriks is gefundeer op die toekomstige koste van arbeid teenoor die toekomstige koste van masjinerie. As 'n finale stap word voorgestel hoe die Suid Afrikaanse bosbedryf kan voorberei om die toekoms tegemoet te gaan.

Resumen

Two different types of recombinant viruses each carrying one of two foreign genes, enhanced green fluorescent protein (eGFP) or Cre recombinase, were constructed based on the SFV4 backbone. In the first type of construct the transgene was inserted in the non-structural ORF, between the coding sequences for nsP3 and nsP4, flanked by processing sites recognised by the nsP2 proteinase. In the second type of constructs the 2A sequence from foot-and-mouth disease virus was added to the C-terminus of the foreign gene and this was placed between the capsid and the p62 protein of SFV4 (structural ORF). All recombinant viruses constructed were viable and able to replicate in vitro. eGFP expressing viruses reached titres similar to those of wild-type virus whereas Cre expressing viruses were slightly attenuated. For viruses with the marker gene inserted in the non-structural ORF, western blotting showed that the processing pattern of the non-structural polyprotein was similar to that of SFV4 and verified the expression of both foreign genes. In vivo, following intracerebral inoculation, all viruses caused encephalitis. Viruses expressing the foreign gene as a cleavable component of the structural ORF induced disease slower than SFV4 or viruses carrying the transgene in the replicase ORF. eGFP fluorescence was stronger and occurred later in infection when expressed in the structural ORF than in the replicase ORF. eGFP expression from the replicase ORF marked only recently infected cells; a property useful in pathogenesis studies. eGFP expressing viruses demonstrated the same cell tropism as SFV4 with infection principally of neurons and oligodendrocytes. None of the mice infected intraperitoneally with SFV4 or the recombinant viruses succumbed to infection demonstrating poor neuroinvasiveness. These viruses are likely to be highly valuable for in vivo pathogenesis studies.

Resumen

This study explored how people-forest relationships are forged around Kenya’s Nyandarwa Forest Reserve, and how Indigenous Knowledge Systems of Agĩkũyũ people around the Reserve might contribute to healthy, sustainable people-forest relationships in light of the country’s changing social, economic, and political situations. The study sought to examine:1) how the indigenous communities around Nyandarwa Forest Reserve traditionally understood and sustained interdependencies with the forest; 2) how these interdependencies have transformed consistent with Kenya’s post-independence changes in social, economic, and political situations; 3) to what extent local, national, and international efforts to promote healthy sustainable people-forest relationships are incorporating local communities’ Indigenous Knowledge Systems (IKS); and, 4) how these communities’ IKS might inform the proposition of an environmental conservation framework for sustainable people-forest relationships. The study was guided by post-colonial indigenous research paradigms anchored in decolonizing methodologies. These methodologies were buttressed by indigenous theories that consider communities as spiritual beings with multiple relations. The study was informed by the traditions and cultural heritage of the Agĩkũyũ people, and augmented by Afrocentric philosophies that underlie African ways of knowing and value systems. Data were collected from community groups, elders, the Kenya Forest Service, and archives. The data corpus was analyzed using NVIVO consistent with the study’s theoretical framework and generated themes that address the research questions. In addition, the research participants contributed to the process as this study sought to elevate the community to the role of co-researchers and to create mutually beneficial long-term relationships. Results show that the pre-colonial manifestation of Agĩkũyũ people-forest relationships were understood through land, that land continues to be a central pillar of Agĩkũyũ indigenous environmental thought, and that one of the historical values of the forest is its role in sustaining the struggle for independence. Further, the study reveals that some indigenous practices tied to sacred sites and food sovereignty have endured, different governance regimes have shifted the way people-forest relationships are constructed, and the Agĩkũyũ have been continuously mobilizing to protect their landscape. In the end, this study suggests how IKS can contribute to forging sustainable people-forest relationships, arguably the planet’s most threatened resource.

Resumen

In the European Union, forests and other wooded areas cover a total of 177.8 million hectares, which represents approximately 40% of the EU total area and an area similar to that used for agricultural purposes (183.9 million hectares). Germany, Spain, France, Finland and Sweden make up over three-fifths of the area covered by forests in the EU. Our paper shows the distribution of forested areas in the EU and their importance in comparison with the agricultural area of each Member State. In 2014, the EU represents about 12 % of global timber volume harvested timber from forests and woodlands on its surfaces rising to 392.9 million m3. Forestry, logging and related services covering timber production and extraction and harvesting of forest products that grow in the wild. In addition to industrial round wood, forests produce firewood, too. In some regions, non-timber forest products are also an important source of local income. In the research approach, we considered necessary and appropriate to perform a comparative analysis of the situation of Romanian forest similar to that of the main European Union countries, to identify measures that some of them have tried, and even managed to increase a rational exploitation of afforested areas forest resources. The results conducted to a comparative analysis of the National Forest and the main EU countries’ Systems, to identify possible starting points for grounding new sustainable development strategies, given their similar experience.

Resumen

This study demonstrates that the economic activity of the Amazon's natural forest has great potential yet to be developed when considering Non-Timber Forest Products (NTFPs) and those coming from agro-ecosystems (SAFs). Preliminary financial analyzes, in systems that are still incipient, point to a great potential for profitability of these alternative systems compared to traditional activities such as soybean and livestock farming, with the advantage of being conducted without degradation and deforestation, allowing the continuation with the support of the Amazonian ecological system. More research is needed to scale successful cases and more “dialogue” between the models of modern agriculture and the traditional knowledge to reach an integrated natural forest management system.
