Beech (Fagus spp.) is one of the most common tree species in Europe and Western Asia. The implementation of sustainable forest Operations (SFOs) in beech forests is therefore crucial in terms of sustainable forest management. This review summarises the state of the art concerning time-motion studies carried out in beech forests, defining the work productivity and the related costs of different harvesting systems applied in these stands. The main focus in recent years on felling and processing operations has been the introduction of fully mechanised systems in beech forests, obtaining satisfactory results in terms of work productivity. However, the working performance is still lower than in coniferous stands. Skidding and forwarding resulted in suitable techniques for ground-based extraction, both showing a clear inclination towards increasing working performance when applying higher levels of mechanisation. Aerial extraction by cable yarders is particularly important in beech forests, considering that these are often located in steep terrains. Further efforts should be dedicated to enhancing the training for operators to extend the application of aerial extraction systems, which ensures good levels of work productivity and limited soil disturbances. In summary, this review aimed to give a clear insight into forest operations in beech forests which could be useful for forest managers, forest engineers and researchers in the sector of sustainable forest operations.

SummaryApproximately 80% of neotropical forests are subject to unsustainable economic practices, such as logging. Spiders are a megadiverse taxonomic group with a particularly great diversity in forest ecosystems and could help indicate the sustainability of logging operations. At six sites at 400–700 m altitude in the piedmont forest of north-western Argentina, spiders collected using pitfall traps and forest structure and spider assemblage structure variables were quantified in order to examine the association between them and to identify indicator spider families. Logging changes forest structure and seems to generate an unsuitable habitat for spiders associated with mature forests. The family taxonomic level is a good surrogate for spider morphospecies. The Mysmenidae, Nemesiidae, Theridiidae, Pholcidae, Hahniidae and Tetragnathidae families were associated with upper canopy cover of 20% or more and with more than two dead fallen trees per 0.1 ha and >15 live trees per 0.1 ha, found in unlogged forests. Bearing in mind that the piedmont forest of north-western Argentina is being logged in the absence of sustainability criteria, we suggest including spiders in monitoring schemes to complement the information obtained from more readily used groups, such as charismatic vertebrates.

This study represents the first attempt of integration, within a Forest Management Plan (FMP), of a Geographic Information System (GIS) and an Analytic Hierarchy Process (AHP) approach for the selection of the most suitable logging method. It is important to underline that the developed methodology is applicable worldwide in each environmental context in which there is a need for planning the intervention and selecting from among several possible logging methods or harvesting systems. Schematically, the main aims of this study were: (i) to develop a GIS-AHP method based on open-access GIS software; (ii) to compare the results of the simulations developed from the statements of two different groups of experts from around the world, to determine the reliability of the predictive probability of the method. The selection of the extraction methods performed with RTS (experts from research and technical sector) input data showed that the most suitable option in the major part of the study area was the cable skidder, followed by the cable yarder, and finally the forwarder. The extraction system selection performed with OS (people from the operative sector) input data revealed limited differences. Thus, considering what was reported above, it is possible to assert that the applied GIS-AHP methodology showed good performance and high consistency in the selection of the best alternatives among different extraction methods. The idea of comparing the results obtained from a survey based on a pool of researchers and forest engineers (RTS) was taken as a target simulation to be evaluated. The method based on data derived from a pool of expert forest operators (OS) was used to check for the results of the other simulation. This is an innovation in these kinds of studies. The results from the consistency check were encouraging, considering that for 51 sub-compartments, only two changed the selected extraction system between RTS and OS.

Menominee Tribal Enterprises (MTE Ltd., Keshena, WI) forest products were certified as sustainably managed in 1992 in recognition of their past performance and commitment to sustained-yield, community based forestry. Their forestry operations are planned and coordinated at the Menominee Forestry Center and represent the cooperative efforts of three agencies: (1) Menominee Tribal Enterprises, (2) Wisconsin Department of Natural Resources and (3) the Bureau of Indian Affairs. After 140 years of harvesting, about 63% of the productive forest land (55,850 ha) within the Menominee reservation is thought to be fully stocked today and includes many impressive stands of large white pine, sugar maple and red oak. In October 1995, Menominee foresters organized a tour of the Reservation forests and explained their forest management practices. In this paper, some highlights of what was observed and learned during the tour are described, including the Menominee's approach to forest management and their main forest management activities. Key words: Menominee, partial cutting, forest sustainability, forest certification

Minimizing the impact of timber harvesting on forest stands and soils is one of the main goals of sustainable forest operation (SFO). Thus, it is necessary to make an accurate assessment of forest operations on soil that is based on the SFO perspective. The present study was conducted according to SFO principles to investigate the time required for the natural recovery of soil after disturbance by skidding operations in some Iranian forests. The physical, chemical, and biological properties of soil found in abandoned skid trails from different time periods were compared with undisturbed forest soils. The soil bulk density, the penetration resistance, and the microporosity of a 25-year-old skid trail were 8.4–27.4% and 50.4% greater, and the total porosity, macroporosity, and soil moisture were 1.9–17.1% and 4.6% lower than the undisturbed area. In a 25-year-old skid trail, the values of pH, Electrical conductivity (EC), C, N, available P, K, Ca, and Mg, earthworm density, and biomass were lower than in the undisturbed area, and the C/N ratio value was higher than in the undisturbed area. High traffic intensity and slope classes of 20–30% in a three-year-old skid trail had the greatest impact on soil properties. In order to have sustainable timber production, SFO should be developed and soil recovery time should be reduced through post-harvest management operation.

"Contribution of Forest Stewardship Council Certification to Sustainable Forest Management of State Forests in Selected Southeast European Countries."

In recent decades, the concept of forest certification under the Forest Stewardship Council (FSC) has been widely adopted in selected Southeast European countries (Bosnia and Herzegovina, Croatia, Serbia, and Slovenia). As sustainability is traditionally recognised as a leading principle in the forest management doctrine in these countries, the aim of this study was to understand whether, and how, FSC forest certification contributes to the sustainable management of state forests. The research was carried out in two phases. First, in order to assess forest management compliance with FSC standard, non-conformities for the period 2014–2018, identified in audit Public Summary Reports, were analysed in all public companies that managed state-owned forests in selected countries. Further, in-depth, semi-structured interviews with the professionals responsible for forest certification in these companies were conducted (n = 11) to determine the contribution of forest certification to the economic, ecological, and social aspects of sustainable forest management. In total, 185 non-conformities were analysed. The results showed that FSC certification was successful in addressing certain problems in forest management practices and contributed to sustainable forest management, mainly covering social and ecological issues. The most frequently identified non-conformities were those related to FSC Principle 4 Community relations and worker’s rights (32.3% of all non-conformities) and Principle 6 Environmental impact (30.4% of all non-conformities). The contribution of FSC certification to sustainable forest management is mainly reflected in the following aspects: Worker’s rights; health and safety of employees; availability of appropriate personal protective equipment; consultation with local people and interest groups; awareness of environmental impacts of forestry operations; waste disposal and storage of fuel; improving the image of forest companies and maintenance of high-conservation-value forests. The majority of non-conformities were minor and required procedural changes to be closed. Moreover, there are no statistically significant differences between the countries with regard to the number of non-conformities for all principles. It can be concluded that FSC certification, as a market-driven mechanism, plays an important role by influencing forest management practices and business operations of public forest companies in a positive manner.

The Swiss forest between wood supply and multifunctionality (essay) Swiss forestry operations have been in deficit for decades. Timber prices fall while production costs rise. At the same time, demand for non-market forest services continues to increase. The challenge is to ensure a sustainable timber supply from Swiss forests in the future, while taking into account the multifunctionality of the forest. According to the results of a Swiss national science foundation research project on this issue, non-market forest services are highly valued by the population. The study also identified significant potential for improving the performance of forest operations, in particular by achieving economies of scale. In addition, the exploitation and maintenance of the forest has positive externalities, which justifies the payment of targeted public subsidies to the forest sector.

Research highlights: Funding forest management with subsidies from carbon offsetters is a well-documented mechanism in tropical regions. This article provides complementary insights into the use of voluntary offset contracts in temperate forests. Background and objectives: The mitigation of greenhouse emissions has become a major global issue, leading to changes in forest management to increase the capacity of forests to store carbon. This can lead to conflicts of use with other forest ecosystem services such as timber production or biodiversity conservation. Our main goal is to describe collective actions to fund carbon-oriented forestry with subsidies from carbon offsetters and to analyze how their governance and functioning prevent conflicts pertaining to multi-functionality. Materials and methods: We assembled an interdisciplinary research team comprising two ecologists, a social scientist, and an economist. Drawing on a conceptual framework of ecosystem services, social interdependencies, and collective action, we based our qualitative analysis on semi-structured interviews from two French case studies. Results: Carbon-oriented intermediary forest organizations offer offset contracts to private firms and public bodies. Communication is geared toward the mitigation outcomes of the contracts as well as their beneficial side effects in providing the ecosystem services of interest to the offsetters. Subsidies then act as a financial lever to fund carbon-oriented forestry operations. Scientific committees and reporting methodologies serve as environmental, social, and economic safeguards. Conclusions: These new intermediary forest organizations use efficient forest operations and evaluation methodologies to improve forest carbon storage. Their main innovation lies in their collective governance rooted in regional forest social-ecological systems. Their consideration of multi-functionality and socioeconomic issues can be seen as an obstacle to rapid development, but they ensure sustainability and avoid conflicts between producers and beneficiaries of forest ecosystem services. Attention must be paid to interactions with broader spatial and temporal carbon policies.

With the increasing use of forest biomass, concerns about negative impacts have been raised in the debate. The aim of this study was to find out the attitude of university students towards the energy use of forest-based biomass and how different areas of sustainable forest operations were addressed. The survey was conducted over two years (2018–2019) with both full-time students at university and distance learning students who study alongside their work. Background information such as gender, nationality and field of study was collected from students. Most of the students currently considered the energy use of forest biomass to be sustainable. Many replies stressed that the situation could change if the use of forests is increased from the present circumstances. The main factors mentioned that led to forest-based bioenergy being sustainable were positive felling balance, compliance with forest certification, use of waste fractions and implementation of the Renewable Energy Directive (RED II) directive, while the loss of biodiversity, over-exploitation of forests, C debt and the cascading principle were factors that led to forest-based bioenergy being unsustainable. Student background variables had no effect on responses except for the field of study.

The aim of this work is to rise up a procedure to support the management plans. This research is divided into seven chapters. In the first chapter, the introduction, with
justification and the objectives of the work are referred. In the second chapter, a review of the literature about management of natural tropical forests is done, considering the difficulties, general and special conditions for effective implementation of the management of natural tropical forests. In the third chapter, it
is defined the fundamental point of this work: to propose a procedure for calculating the cutting rate using the method BDq in combination with the growth of species with
similar percentage volume increment. In the fourth chapter, it is suggested a procedure for detailed logging plan: road network planning; it was calculated the load
and time of the skidder cycle; designed the size and performance of teams and all is compared with outputs obtained on the field. In the fifth chapter, using the method of ratio of diameter movement , fed with data from the permanent plot, a stand table projection of the diameter classes to assess the sustainability of cut rate for the period is done. The sixth chapter is a proposal for monitoring the management system. Finally, the seventh chapter analyses the economic viability of the
compartment. Regarding the results for cutting rate from the compartment of 547 ha have been identified 3 groups of species with different rates of growth. Cut intensities
were defined as 32.58% for group I; 48.62% for group II; and 56.23% % for group III. The total extraction for all compartment was 50.8%. The potential of the compartment
was 17,021.46 m³ (31.11 m³ / ha), and the sustainable rate of cutting was 8,649.97 m³ (15.81 m³ / ha). To recover this extraction it is necessary a MAI of 0.63 m³ / ha /
year. The logging indexes were: the optimal distance between landings was 540m. The optimum secondary road density calculated was 18.49 m / ha and the actual
obtained in the field is, 21m/ha. The calculation of optimal number of landings was 24, to serve to 23 hectares each one, with capacity of 368m³ of timber in two stages,
comprising only 0.22% of the area of the compartment. The maximum load capacity to Skidder was 7 ton in clay ground, dry, without structure and with a maximum gradient of 15%, and 4.6 ton in sand soil, slope of up to 10%. The average cycle time to skid was 11 minutes and 42 seconds; the average load of 6.11 tons was found. The stand table projection indicated an increase of mean annual increment (MAI) of 0.64 m³ / ha / year in the commercial classes (up to 45 DHB) and 0.67 m³ / ha / year in the above classes of 25 DBH. The ingress in the commercial classes was 4.17
trees per hectare to a cut cycle of 25 years. These data report that the recovery is feasible for the rate cut foreseen. It was also simulated a removal of all commercial
classes (31.11 m³ / ha), and the result to cut cycle was an increment was 0.35 m³ / ha / year replacing only 28%. This reinforces the importance of evaluating the
structure of the forest, besides the sustainable rate cut, to guarantee a replacement of adequate MAI. The girth limit for maximum production was 75 cm of DHB in this
stand. The checklist about the sustainability of logging operations shows the adaptation of the enterprise to the new concepts of management. About the economical valuation, it was positive according Net Preset Value for the taxes of 6% a.a ., getting R$ 439,81/ha and R$ 240.579,31 for all compartment of 547 ha.Esta pesquisa visa levantar procedimentos que devem ser incluídos nos planos de manejo. O trabalho está dividido em sete capítulos. No primeiro capítulo, são mencionados introdução, justificativa e objetivos do trabalho. No segundo capítulo, é realizada a revisão bibliográfica sobre o manejo das florestas naturais tropicais, avaliando as dificuldades, condições gerais e específicas para implantação efetiva do manejo das florestas naturais tropicais. No terceiro capítulo, foi definido o ponto fundamental do trabalho: propor um procedimento para cálculo da taxa de corte utilizando o método de Área Basal Máximo DAP-q em combinação com o crescimento de espécies com ritmo semelhante, baseado em seu incremento percentual em volume. No quarto capítulo, é detalhado o procedimento sugerido de planejamento da exploração, o planejamento de rede de estradas, o cálculo do ciclo de arraste e carga do skidder, além de projetado o dimensionamento das equipes e das performances e comparado com resultados obtidos na exploração. No quinto capítulo, utilizando-se o método de razão de movimentação, alimentado com dados de crescimento das espécies segundo as parcelas permanentes, é feita uma projeção das classes diamétricas visando avaliar a sustentabilidade da taxa de corte para o período considerado. No sexto capítulo, é apresentada uma proposta de monitoramento das empresas com alguns resultados de pesquisas já realizadas na área ou em compartimentos contíguos. E, finalmente, no sétimo capítulo, são realizadas análises de viabilidade econômica do compartimento em diferentes situações de venda da madeira. Com relação aos resultados para taxa de corte do compartimento de 547 ha, foram definidos 3 grupos de espécies com diferentes ritmos de crescimento. Assim, foram definidas intensidades de corte de 32,58% para o grupo I; 48,62% para o grupo II; e 56,23% para o grupo III. Em conjunto, a extração ficou em 50,8% sobre as classes comerciais. O potencial do compartimento era de 17.021,46 m³ (31,11m³/ha) e a taxa de corte sustentável orçou em 8.649,97 m³ (15,81 m³/ha). Para recuperar essa extração, será necessário um incremento médio anual de 0,63 m³/ha/ano. Os cálculos de planejamento da exploração indicaram para a distância ótima entre estaleiros o valor de 540 m. A densidade ótima de estradas calculada foi de 18,49m/ha e a real obtida em campo foi 21m/ha. O número ótimo de pátios calculado foi de 24 pátios de estocagem, visando servir a 23 hectares cada um, com capacidade de 368m³ de madeira por pátio em duas etapas, perfazendo apenas 0,22% da área do compartimento. As cargas máximas calculadas para o skidder na unidade de produção foram de 7 ton em terreno argiloso, seco, sem estruturação e com um máximo de 15% de inclinação, e de 4,6 ton em areia solta e inclinação máxima de 10%. O tempo de ciclo médio do trator de arraste foi de 11 minutos e 42 segundos; a carga média encontrada foi de 6,11ton. A prognose de incremento indicou um incremento médio anual (IMA) de 0,64m³/ha/ano nas classes comerciais (acima de 45 de DAP) e 0,67m³/ha/ano nas classes acima de 25 de DAP. O ingresso nas classes comerciais foi de 4,17 árvores por hectare para um ciclo de 25 anos. Esses dados informam que a recuperação é viável para a taxa de corte considerada. Foi também simulada uma remoção de todas as classes comerciais (31,11 m³/ha), e o resultado como incremento para 25 anos foi de 0,35/ha/ano, repondo apenas 28% do retirado. Isso reforça a importância da avaliação da estrutura da floresta, além da taxa de corte, para garantia de um IMA passível de reposição. A classe de DAP de máxima produção nesse povoamento é a de 75 cm. Foi elaborado um checklist para checagem da sustentabilidade do sistema de manejo utilizado, havendo boa aceitação da empresa às novas técnicas de exploração. A avaliação econômica foi positiva com relação ao valor presente líquido a uma taxa de 6% a.a., atingindo R$ 439,81/ha e R$ 240.579,31 para todo o compartimento de 547 ha.

Face à un environnement incertain marqué par une instabilité sans cesse croissante, les entreprises s’efforcent de rechercher la performance à la fois globale et durable considérée désormais comme un levier non seulement de pérennité, mais aussi d’avantage concurrentiel primordial (Porter et Kramer, 2006; Crane et Matten, 2004). Ainsi, la responsabilité sociétale de l’entreprise (RSE) est perçue comme un thème fédérateur en sciences de gestion et de par sa dimension sociétale dans les sciences économiques et sociales prenant tout son sens dans le management opérationnel des entreprises. Considérée comme le prolongement de la prise en compte du développement durable (rapport Brundtland 1987) dans ses implications managériales, la RSE cristallise l’attention de nombreux chercheurs depuis plusieurs décennies, notamment dans sa dimension sociale, environnementale et normative (ISO 14000) depuis une vingtaine d’année et sociétale (ISO 26000) depuis les années 2000. Si la littérature foisonnante sur le concept de RSE reste en débat, force est de constater qu’elle traite très peu des mécanismes de construction des pratiques RSE et moins encore du rôle que les stakeholders jouent dans cette construction. Dans un tel contexte, prenant appui sur la stakeholder theory (Freeman, 1984; Oliver, 1991; Clarkson, 1995; Mitchell et al., 1997; Sethi, 1995; Rowley, 1997), l’analyse des données collectées suite à une investigation de huit mois auprès de six entreprises forestières au Cameroun, révèle d’une part que le modèle de Carroll (1979, 1991) de la RSE est contingent au contexte et que le comportement stratégique orienté RSE des entreprises du secteur de l’industrie forestière au Cameroun est fortement corrélé à la nationalité de l’entreprise. D’autre part, cette étude fait état de ce que la variable « champ d’activité » a un effet non déterminé sur le comportement stratégique adopté par les entreprises de ce secteur forestier. Enfin, cette recherche révèle également que la certification forestière FSC représente le gage d’un engagement volontaire en matière de RSE des entreprises d’exploitations forestières au Cameroun. La présente recherche ouvre la voie aux travaux futurs pour internaliser les pratiques de la RSE par les parties prenantes dans le management stratégique des entreprises les plus confrontées aux défis environnementauxIn an uncertain environment that is also marked by a growing instability, firms try to seek a global and sustainable performance which is considered as a lever not only for longevity but also for competitive advantage (Porter and Kramer, 2006; Crane and Matten, 2004). Thus, corporate social responsibility (CSR) is perceived as a unifying topic in management science and, by its societal dimension, in the economic and social sciences. Considered as an extension to the consideration of sustainable development in its managerial implications (Brundtland report, 1987), CSR has been at the attention of a large number of researchers for several decades now, in particular for twenty years in its social, environmental and normative dimension (ISO 14000) and since the 2000’s in its societal nature.While the concept of CSR is still under debate in its rather large literature, it should also be noted that this literature is usually silent on the construction mechanisms of CSR practices and even more on the role that stakeholders play in this construction.In this context, and relying on stakeholder theory (Freeman, 1984; Oliver, 1991; Clarkson, 1995; Mitchell et al., 1997; Sethi, 1995; Rowley, 1997), the present analysis of the collected data from an eight-month-long in-depth investigation of six forestry firms in Cameroun yields several findings: First, the CSR model in Carroll (1979, 1991) is contingent to the context and the strategic CSR behaviour of the different firms in the forestry industry in Cameroun is strictly correlated to the nationality of these firms. Second, this study shows that the “field of action” variable has a non-significant effect on the strategic behaviour adopted by the firms in this forestry industry. Finally, this research also reveals that the Forest Stewardship Council (FSC) certification represents the deposit of a voluntary commitment in terms of CSR of the forestry exploitation firms in Cameroun. The present work also opens new lines for future research focussing on the internalisation of the CSR practices by the contracting parties in strategic management of the firms that are in direct confrontation to the environmental challenges

Mestrado Mediterranean Forestry and Natural Resources Management (MEDFOR) - Instituto Superior de Agronomia - ULIn recent years, an integration of water production values for forest ecosystems into forest management planning models has become increasingly important in sustainable forest management. The reason is that both for surface and groundwater resources quantity and quality – forests play a vital role. The main objective of this work is to produce an analysis of forest management planning methods that have been implemented the most frequently for assessing an optimal integrated forest and water management for forested catchments. The research was developed within the framework of Alternative Models and Robust Decision-Making for Future Forest Management (ALTERFOR) Project; being developed to assess Decision Support System (DSS) tools that support sustainable forest management by means of including a variety of ecosystem services. For that purpose, we use a taxonomy of water related ecosystem services based on the classification scheme estimated based on the findings of the project. The taxonomy is used to develop a query of relevant references from 2754 journals, encompassing 46 scientific categories, stored in the ISI Web of Science database over the last 30 years. Query results were analyzed, and decision-making methods were classified and assessed according to their supporting role to forest managers in addressing specific ecosystem services. As forest managers are often confronted with conflicting preferences by owners and stakeholders regarding ecosystem services target levels, the query will further address the potential of decision-making methods to facilitate negotiation and consensus building

Reducing the soil impact of forest operations is a priority for improving sustainable forest management. Logging activities may alter soil in terms of both compaction and rutting. The overall aim of this thesis was to use an emerging methods approach to summarize how ground-based logging systems affect the soil in different working conditions. The thesis is based on four studies: the first applied a meta-analytic approach to machinery-induced soil compaction and its effect on the growth of forest plants; two studies tested new methods of rutting estimation after the trafficking of forest machinery; the last study addressed soil damage caused by skidding and forwarding under specific work conditions. The studies investigated the effects of ground-based extraction systems, including physical soil parameters for assessing compaction (i.e., bulk density and soil penetration resistance) and emerging methods for rutting measurements (i.e., 3D soil models obtained by portable laser scanning and Structure from Motion derived from photogrammetry, with images collected from a ground-based stand or higher altitudes by drones). The results of the meta-analysis showed the effects of soil compaction caused by machine trafficking on both morphological and physiological plant characteristics, especially in fine-textured soil. The most notable results of the other studies highlighted the irrelevant role of driving direction on soil damage during forwarding on a 25% slope. On the contrary, to reduce soil compaction, downhill skidding is preferable to uphill skidding. The results showed that low tyre pressure may mitigate the effects of forwarding on soil compared with higher tyre inflation pressure (i.e., 150 kPa vs. 350 kPa). The pressure on the ground caused by logging vehicles affects the wheel tracks, but to some extent, also the soil between the tracks. In general, the area affected by soil impacts was larger in skidding than forwarding due to the effect of dragged logs. Rutting estimation with photogrammetry and portable laser scanners showed promising results in terms of high-resolution data. It also reduced the time necessary for field surveys and obtaining accuracy compared to manual measurements. Nevertheless, the presence of free water in ruts or brush mats can affect the accuracy of results.

Recent literature has recommended that life cycle assessments (LCA) of forest bioenergy supply chains consider the impact of biomass harvest on ecosystem carbon stocks as well as the net emissions arising from combustion of various forms of biofuels compared with reference fossil fuel systems. The present study evaluated the magnitude and temporal variation of ecosystem C stock changes resulting from harvest of roadside residues and unutilized whole trees for bioenergy. The Carbon Budget Model (CBM-CFS3) was applied to the Gordon Cosens Forest, in northeastern Ontario, along with the Biomass Opportunity Supply Model (BiOS-Map), for cost analysis of different types of biomass comminution. Natural gas (NG) steam and electricity, grid electricity, and coal electricity reference systems were analyzed for a pulp and paper mill.
The findings showed that the forested landscape becomes a net sink for carbon following the 20th year of roadside residue harvest, compared to whole-tree harvest, where the forested landscape remained a net source of carbon over the entire 100 year rotation. The cumulative ecosystem carbon loss from whole-tree harvest was 11 times greater compared to roadside residue harvest. BiOS-Map analysis suggested that due to technical and operational limits, between 55%-59% and 16%-24% of aboveground biomass was not recovered under roadside residue and whole-tree harvest respectively. The cost of delivering roadside residues was estimated at $52.32/odt–$57.45/odt, and for whole trees $92.63/odt–$97.44/odt.
The Life Cycle Assessment (LCA) analysis showed break-even points of 25, 33 and 6 years for roadside residues displacing NG steam, NG electricity, and coal, respectively. No GHG reduction was achieved when forest biomass was used to displace grid electricity that is generated in Ontario. Whole-tree bioenergy resulted in no GHG reduction for NG displacement, and a break-even point of 70-86 years for coal. A net GHG reduction of 67% and 16% was realized when roadside residues and whole trees were used to displace coal, compared to 45% and 38% when roadside residues were used to displace NG steam and NG electricity, respectively. Therefore, it is recommended that bioenergy deployment strategies focus on the utilization of roadside residues, if the main goal is GHG mitigation.

AbstractClimate-smart forestry can be regarded as the evolution of traditional silviculture. As such, it must rely on smart harvesting equipment and techniques for a reliable and effective application. The introduction of sensors and digital information technologies in forest inventories, operation planning, and work execution enables the achievement of the desired results and provides a range of additional opportunities and data. The latter may help to better understand the results of management options on forest health, timber quality, and many other applications. The introduction of intelligent forest machines may multiply the beneficial effect of digital data gathered for forest monitoring and management, resulting in forest harvesting operations being more sustainable in terms of costs and environment. The interaction can be pushed even further by including the timber processing industry, which assesses physical and chemical characteristics of wood with sensors to optimize the transformation process. With the support of an item-level traceability system, the same data could provide a formidable contribution to CSF. The “memory” of wood could support scientists to understand the response of trees to climate-induced stresses and to design accordingly an adaptive silviculture, contributing to forest resilience in the face of future changes due to human-induced climate alteration.

AbstractUnstable rock slopes are likely to cause rockfalls, threatening human lives and properties, industrial activities, and transportation infrastructures in mountain areas. There is an increasing demand to forecast and mitigate the potential damage of rockfalls by developing a reliable early warning system. In this thesis, an unstable mountain slope in northern Italy was selected as the research target. A microseismic monitoring network has been operating since 2013 as a field research laboratory to study the microseismic monitoring technique in the perspective of developing rockfall early warning systems. Locating microseismic events is a basic step of this technique to obtain the location of developing cracks as possible precursors of rockfalls. However, it is still a challenging task due to the heterogeneity of fractured rock slopes. The main purpose of this thesis is to address the issues related to event localization for microseismic monitoring strategy applied to the unstable rock face. Graphical Abstract

AbstractThe provincial governments of Papua and West Papua have expressed their commitments and enacted policies to develop Papua Land in a sustainable manner through the issuance of Papua 2100 Vision, the 2019 Manokwari Declaration, and the ‘green’ spatial plan of Papua province. However, the implementation of these policies in balancing protection of forests and improvement of livelihood of indigenous Papuans has been slow. By employing a political economy approach, the study explores how interactions between the political economy structure, institutions, and actors have resulted in slow implementation of such commitments, particularly in reviewing the compliance of land-based industry licenses and acknowledging customary (adat) areas. The study was conducted between February 2020 and March 2021 and encompassed approximately 50 key informant interviews – including donors, civil society organizations, adat leaders, national and subnational governments, observers, academics, and journalists – and document review. The findings of this study suggest that the reform is mainly driven by development partners and limited numbers of bureaucrats that align with the indigenous Papuans’ interest to protect their land from outsiders. The small coalitions were successful in focusing their effort to enact green policies in the two provinces. However, the study highlights constraints faced by these actors to turn the policies into actions: (1) the existence of wide array of powerful actors – non-Papuans and Papuans – with strong economic and political interests identified at central, provincial, and regency level to hinder the enforcement of problematic land-based licenses and clarify adat areas; (2) the absence of broad-based political support. These have hampered the implementation of the green policies under the two aspects above. This study recommends reviewing policy at the national level to create enabling environment for green policies implementation in both provinces, e.g., to review the Omnibus Law, supporting the regency-level actors to accelerate issuance of the perda PPMHA and local-level regulations on adat-managed areas, supporting licenses review in Southern part of Papua Province to limit the operation of these businesses to expand in forest areas and disrespect adat rights over their lands, and exploring engagement with the opposing parties at all administrative level.

This chapter highlights the influence of mountain forests on runoff patterns in alpine catchments. We discuss the forest impact at different spatial scales and bridge to the requirements for an integrated natural hazard risk management, which considers forest as an efficient protection measure against floods and other water-related natural hazards. We present results from a wide range of research studies from Austria, which all reveal the runoff-reducing effect of forest vegetation in small and medium-size catchments (< 100 km2). Forests also contribute to runoff reduction in heavy rainfall events in macro-scale catchments (> 100 km2), e.g., by reducing surface runoff and delaying interflow, but above all by stabilising slopes and therefore reducing bedload transport during major runoff events. To avoid that forests become a hazard due to enhanced driftwood release, managing of steep riparian slopes for a permanent forest cover (“Dauerbestockung”) is a basic prerequisite. Often protective effects of forests are impaired by man-made impacts like dense forest road networks, insensitive use (e.g., false design of skid roads, compacting machinery, forest operations during adverse weather on wet and saturated soils), and delayed or omitted reforestation and regeneration. Flood risk management in mountain regions should include Ecosystem-based Disaster Risk Reduction measures, with particular emphasis on sustainable and climate change-adapted management of protective forests. This will require integral and catchment-based approaches such as comprehensive management concepts coordinated with spatial planning, and verifiable, practicable and correspondingly adapted legal guidelines as well as appropriate funding of protective forest research to close the existing knowledge gaps.

The forestation and reforestation activity registers a high dynamics in national territory, very implemented in the aftermath of the great fires that occurred between June and October 2017 and with the revision of the Regional Forest Management Programmes. In this context, the Directorate-General for Cultural Heritage (DGPC) and the Regional Directorates for Culture formed a Task Force (TF) for the definition of procedures and regulations in the context of safeguarding of archaeological heritage in forestry and intensive agriculture projects. Within the scope of forestry projects, the TF produced a set of guidelines relating the safeguarding of the archaeological heritage, to be implemented in multi-annual plantations with impacting techniques of soil mobilization (namely: removal of stones, heavy mechanical scarification, subsoiling, ground levelling, mega ridges-furrows, and terracing, among others). Another of the TF activity area is related with the preparation of awareness raising actions, both for stakeholders in local administration, with obligations in territory management, and for those with interests associated with forestry, which includes owners, investors and forest managers. Thus, it is intended to advertise the initiatives that have been developed in order to introduce and promote good practices related with the safeguarding of the cultural heritage in forestry operations, in order to stimulate a sustainable relationship between man and his territory, namely, with the Archaeological Heritage, a finite and non-renewable resource.

Afforestation and reforestation of arable land enhances soil C sequestriationn. Optimized forest management to sustainably maximize stocks of soil organic carbon. Coniferous forests store more C in the topsoil whereas broadleaf forests store more C in the subsoil. However, on the landscape scale total soil C stocks are similar. Current forest management focuses on increased resistance and resilience. Thinning intensity leads to stable SOC stocks in the long run. Stand replacing disturbances impose significant soil C losses. Controlling the density of browsing game populations is a required ancillary management measure. Tree harvesting operations lead to transient soil C losses. The magnitude depends on the severity of interventions. On nutrient rich soils with low C stocks in the forest floor, whole tree harvest might not affect soil C sequestration, whereas at nutrient poor soils as well as at erosion prone sites, removal of biomass and/or harvest residues reduces soil C sequestration.

Poland is in one of a leading position in Europe in terms of forested area. Forests grow over 9.4 million hectares, which is 29.5% of the territory of Poland. The vast majority of this area is forests owned by the state, out of which almost 7.6 million hectares are under the management of the State Forests Holding. Educating society about forestry and environment is one of the main priorities of the State Forests. The State Forests’ educational offer is aimed at children, youths and adults, including people with disabilities. It is all about popularising knowledge about forestry and sustainable forest management. This article focuses on the social actions of the State Forests’ operations based on an analysis of the data obtained from reports made by the State Forests. These information and materials were analysed to identify the social aspects of actions carried out by the State Forests in Poland. The authors analysed various kinds of activities of the State Forests connected with social aims. The results of the analyses were presented in table format. The results were used to analyse and describe the social aspects of the State Forests’ operations in the forested area in Poland. The social actions of the State Forests in Poland have been very positively evaluated by the authors based on the achieved analyses.

In Lithuania, forests are managed by Lithuanian State Forest Enterprise, municipalities, ministries, etc. and private forest owners. About 50% of all forest land is State importance, privately owned forests cover 40% of forest land, and about 10% of forest land belongs to forests reserved for restitution. Forest management of private ownership force many challenges, because private forest owners are people, who have purchased or received the property after restitution, and often lacks knowledge about forest resources, its dynamics and sustainable forest management. As remote sensing is a valuable source for forest monitoring, because it provides periodic data on forest resource and condition status, these methods are gaining increased attention worldwide. In this context, more scientific efforts are made at developing remote sensing derived geo-spatial data services for sustainable forest management through a web service platform, which would integrate geo-information into daily decision making processes and operation for private forest owners. This article presents a review of privately owned forests’ statistics, questionnaire-based survey about GIS usage and demand for forest owners in Lithuania and links available sources of open geo-spatial data useful for sustainable forest management.

Peculiarities of business logistics are related to sustainable transferring processes, which has always been a mundane task of trade processes. The lack of obstruction of the constant flow of this operation causes disruption to the whole economy and can lead not only to the loss of the foremost profits but also negatively influence the sustainable business logistics development. In pursuance of a strong logistical basis, any business entity should have a variety of practices for managing projects of this kind. Unfortunately, recent scientific explorations overlooked the importance of sustainable project management factors, especially during the Covid-19 situation, and rarely focused on how the implementation of these projects changed in the business logistics over the past few years. Based on a scientific litera-ture review, a set of factors influencing sustainable business logistics projects management both externally and inter-nally was identified. Study results showed that external factors influencing sustainability were related to environmental expenditure, local procurement, and the presence of the market as well as the internal connecting reduced resource exploitation, strategy and project life cycle towards rendering effective business logistics projects for the companies operating mainly on third-party logistics (3PL) and ground transport basis.

Abstract Well integrity in the oilfield is one of the challenges that petroleum engineers face, as they seek to monitor well corrosion in the field to optimize well performance. Most of these fields can be categorized as brownfields, with some of the wells considered aged and have expected integrity issues. To achieve sustainable production targets with cost-effective and safe operations from these fields requires a close monitoring of the integrity of all elements involved in the production chain. Addressing these challenges requires the engineers to coordinate and analyze several data elements, including casedhole, openhole, reservoir, well, and production data from multiple sources. Another challenge is to create and automate a corrosion workflow that saves the engineers’ time and improves efficiency. In this paper, we introduce an innovative workflow that uses the historical corrosion data while integrating the multiple production and reservoir variables. The innovative approach uses machine learning (ML) algorithms to provide a powerful tool for workover (W/O) candidate selection and for optimizing the corrosion evaluation frequency, which are required in different areas of the fields. Different ML methods (random forest classification and neural net) were applied on training data. Different models were created, and the best model will be used. This offered key insights on the rate of corrosion and corrosion patterns. Further, the developed workflow was designed to be self-sustaining and acting as a surveillance tool for monitoring the integrity of the wells. The first step of the workflow was to start with organizing and auditing the available corrosion data, followed by a review and analysis of existing openhole, casedhole, production, and reservoir engineering data. This approach led us to understand the extent and severity of corrosion in terms of the corrosion rate and the corrosion index. The corrosion logs were digitally interpreted depth-wise in order to explore the maximum metal loss for each interval. New animated conformance corrosion maps were created. The successful diagnosis through data analytics in a modern integrated software platform will assist in corrosion monitoring and decision-making. The multiple corrosion maps can be animated to visualize the current corrosion profile and predict the corrosion over time, in addition to ranking the wells for W/O candidate selection.

Sustainable development is playing an increasingly important role in today’s society, and it is essential for companies seeking to meet the needs of the market to pay increasing attention to the application of sustainable development principles in their operations. The enterprise food distribution system is one of the essential activities ensuring the company’s competitiveness in food sector, which ensures timely production and quality of customer service. Nevertheless, the compliance of the company’s distribution system with the principles of sustainable development is a major challenge for most companies. The company’s goal of sustainable development must not forget the main goal - the pursuit of profit; therefore, it is necessary to clearly define the main strategic activities, criteria and evaluation system that would help identify the most suitable solutions for the company to meet both sustainability and profitability expectations. To this end, it is necessary to integrate the institutional dimension and to analyze the food distribution system at the strategic level. The paper analyses the impact of sustainable development on food distribution system to determine which activities are most responsive to sustainable development and company’s goals. The main purpose of the model, presented in the paper, is to help the business sector integrate sustainable development principles effectively in food distribution system, considering the significance of ongoing factors in the system for sustainable development. As study result presented evaluation of international company food distribution system in the context of sustainability according to institutional dimension by identifying value of criteria’s and evaluation main activities in a company distribution system.

Abstract With growing worldwide consensus about the impacts of climate change, the oil and gas industry faces unprecedented pressure to redefine itself, minimize its carbon footprint, and ultimately move towards net zero emissions. It is therefore imperative that the industry can easily and accurately measure its carbon footprint, forecast impact on emissions from operational decisions, monitor key sources of emissions and ultimately minimize it via operational and other optimizations. This need is further accelerated by regulatory, investor, consumer, and market forces, in many cases making it mandatory for corporations to report their carbon footprints. The objective of this work is to present the design and implementation of a carbon estimation and forecasting platform, henceforth called Aurion, to be the one-stop-shop for all the carbon needs of the oil and gas industry. We leverage the Environmental Protection Agency (EPA) Subpart W model and the California Air Resources Board (CARB) OPGEE model as the underlying calculation engines for estimating carbon intensity and footprint. Subpart W is an equipment and inventory-based accounting approach to estimating carbon footprint, and is mandated by EPA for the oil and gas industry for all operations that emit more than 25000 MT of CO2 equivalent. OPGEE is a life-cycle assessment (LCA) tool that estimates the GHG emissions of petroleum production operations from reservoir to transport to the refinery. Using these well-known tools not only provides a robust, tested, and reliable approach to estimate carbon intensity, but also provides standardization and transparency to all calculations, thereby making it thoroughly auditable and consistent across an organization. Aurion provides a user-friendly, cloud based, scalable interface to Subpart W and OPGEE, and allows users to seamlessly integrate various sources of data (public, private, third party) for continuous estimation and monitoring of GHG emissions across the whole organization. It further integrates with production forecasts to provide an estimate for future carbon footprint and intensity to understand the GHG impact of different operational plans. Additionally, the platform provides tools for collaboration, as estimating carbon intensity requires expertise and data from many domains. Sensitivity analysis is also implemented to understand key factors impacting carbon intensity for a field and helps the managers to make sustainable decisions and reduce their carbon footprint. Aurion also provides standard ESG frameworks and customizable surveys for understanding and documenting additional GHG emissions related issues. Finally, Aurion provides tools to aggregate, report and benchmark GHG emissions across an organization.

At Cargill, our ambition is to build the most sustainable food supply chains in the world. From small family farms to global shipping lanes, Cargill works every day to implement new sustainable practices to reduce our impact on the planet and protect people. We know that we must address climate change and conserve water and forests, while meeting the rising demand for food. These are complex challenges, but we have overcome many obstacles to keep our food system resilient and we will continue. We feel a deep responsibility to protect the planet and its people, to ensure a cleaner, safer future for generations to come.We’ve set priorities that account for the diverse environmental, social and economic impacts of our business with clear goals to ensure progress in line with what the science says is needed to keep our people and planet thriving:· Climate: reduce greenhouse gas emissions in our operations by 10% by 2025 and reduce emissions in our supply chain by 30% per ton of product sold by 2030.· Land: transform our agricultural supply chains to be deforestation free by 2030· Water: achieve sustainable water management in our operations and all priority watersheds· Human Rights: promote and respect human rights as outlined in the Universal Declaration of Human Rights and improve the livelihoods of 10 million farmers by 2030 through training insustainable agriculture practices and better access to marketsOur global edible oil solutions are a key part of this ambition. From our new RegenConnect program for soybean oil to our RSPO Segregated palm oil products, we continue to drive sustainability progress against our priorities. But, we cannot do this alone. Through connection and collaboration with farmers, our customers, and global and local communities, we believe our food system will remain resilient.

The need to conduct complex operations over time results in U.S. forces remaining in deployed locations for long periods. In such cases, more sustainable facilities are required to better accommodate and protect forward deployed forces. Current efforts to develop safer, more sustainable operating facilities for contingency bases involve construction activities that redesign the types and characteris-tics of the structures constructed, reduce the resources required to build, and reduce resources needed to operate and maintain the com-pleted facilities. The Automated Construction of Expeditionary Structures (ACES) project was undertaken to develop the capability to “print” custom-designed expeditionary structures on demand, in the field, using locally available materials with the minimum number of personnel. This work investigated large-scale automated “additive construction” (i.e., 3D printing with concrete) for construction applications. This document, which documents ACES energy and modeling, is one of four technical reports, each of which details a major area of the ACES research project, its research processes, and associated results, including: System Requirements, Construction, and Performance; Energy and Modeling; Materials and Testing; Architectural and Structural Analysis.

Several factors contribute to Surinames particular vulnerability to the effects of climate change. It is dependent on fossil fuels, has forests liable to decay, fragile ecosystems, and its low-lying coastal area accounts for 87% of the population and most of the countrys economic activity. Many sectors are at risk of suffering losses and damage caused by gradual changes and extreme events related to climate change. For Suriname to develop sustainably, it should incorporate climate change and its effects into its decision-making process based on scientific- evidence. The State of the Climate Report analyzes Surinames historical climate (1990-2014) and provides climate projections for three time horizons (2020-2044, 2045-2069, 2070-2094) through two emissions scenarios (intermediate/ SSP2-4.5 and severe/ SSP5-8.5). The analysis focuses on changes in sea level, temperature, precipitation, relative humidity, and winds for the seven subnational locations of Paramaribo, Albina, Bigi Pan MUMA, Brokopondo, Kwamalasamutu, Tafelberg Natural Reserve, and Upper Tapanahony. The Report also analyzes climate risk for the countrys ten districts by examining the factors which increase their exposure and vulnerability on the four most important sectors affected by climate change: infrastructure, agriculture, water, and forestry, as well as examining the effects across the sectors. The State of the Climate provides essential inputs for Suriname to develop and update its climate change policies and targets. These policies and targets should serve as enablers for an adequate mainstreaming of climate change adaptation and resilience enhancement into day-to-day government operations.

Community Development Financial Institutions (CDFIs) are grassroots organizations that provide equitable access to financial capital. While a robust body of evidence supports the ability of CDFIs to promote holistic and sustainable development, attempts to systematically evaluate the industry have yielded disparate and often confounding results. We apply an institutional theory lens to examine challenges to meaningful data collection, impact measurement, and program evaluation. Our data show how regulators, major funders, and third-party rating organizations have applied indirect and direct pressures that have systematically lowered the capacity of nonprofit CDFI loan funds. This combination of coercive, mimetic, and normative isomorphic forces has (1) hampered meaningful data collection, (2) created a lack of staff expertise in these areas, (3) raised the cost and complexity of utilizing technology systems to improve evaluation processes, and (4) fostered industry norms which de-prioritize meaningful evaluation. The data suggest several ways for stakeholders to improve these trends. For example, funders might consider providing support which builds organizational capacity via unrestricted operating grants and recurring financial commitments.

Suriname is highly vulnerable to the effects of climate change. Among the factors that exacerbate its vulnerability are its dependency on fossil fuels, the degradation of important ecosystems (e.g., mangroves), and the fact that 87% of the population, and most of the countrys economic activity is located within the low-lying coastal area. Many sectors are at risk of suffering losses and damage caused by gradual changes and extreme events related to climate change. For Suriname to develop sustainably, it should incorporate climate change and its effects into its decision-making process based on scientific- evidence. The State of the Climate Report analyzes Surinames historical climate (1990-2014) and provides climate projections for three time horizons (2020-2044, 2045-2069, 2070-2094) through two emissions scenarios (intermediate/ SSP2-4.5 and severe/ SSP5-8.5).

The State of the Climate Report provides essential inputs for Suriname to develop and update its climate change policies and targets. These policies and targets should enable an adequate mainstreaming of climate change adaptation and resilience enhancementinto day-to-day government operations. It is expected that the Report will catalyze similar efforts in the future to improve decision-making by providing science-based evidence.

Application of 3D technologies to the wide range of Geosciences knowledge domains is well underway. These have been operationalized in workflows of the hydrocarbon sector for a half-century, and now in mining for over two decades. In Geosciences, algorithms, structured workflows and data integration strategies can support compelling Earth models, however challenges remain to meet the standards of geological plausibility required for most geoscientific studies. There is also missing links in the institutional information infrastructure supporting operational multi-scale 3D data and model development. Canada in 3D (C3D) is a vision and road map for transforming the Geological Survey of Canada's (GSC) work practice by leveraging emerging 3D technologies. Primarily the transformation from 2D geological mapping, to a well-structured 3D modelling practice that is both data-driven and knowledge-driven. It is tempting to imagine that advanced 3D computational methods, coupled with Artificial Intelligence and Big Data tools will automate the bulk of this process. To effectively apply these methods there is a need, however, for data to be in a well-organized, classified, georeferenced (3D) format embedded with key information, such as spatial-temporal relations, and earth process knowledge. Another key challenge for C3D is the relative infancy of 3D geoscience technologies for geological inference and 3D modelling using sparse and heterogeneous regional geoscience information, while preserving the insights and expertise of geoscientists maintaining scientific integrity of digital products. In most geological surveys, there remains considerable educational and operational challenges to achieve this balance of digital automation and expert knowledge. Emerging from the last two decades of research are more efficient workflows, transitioning from cumbersome, explicit (manual) to reproducible implicit semi-automated methods. They are characterized by integrated and iterative, forward and reverse geophysical modelling, coupled with stratigraphic and structural approaches. The full impact of research and development with these 3D tools, geophysical-geological integration and simulation approaches is perhaps unpredictable, but the expectation is that they will produce predictive, instructive models of Canada's geology that will be used to educate, prioritize and influence sustainable policy for stewarding our natural resources. On the horizon are 3D geological modelling methods spanning the gulf between local and frontier or green-fields, as well as deep crustal characterization. These are key components of mineral systems understanding, integrated and coupled hydrological modelling and energy transition applications, e.g. carbon sequestration, in-situ hydrogen mining, and geothermal exploration. Presented are some case study examples at a range of scales from our efforts in C3D.
