Forest management approaches for coping with the uncertainty of climate change: trade-offs in service provisioning and adaptability
The role of personal values and personality traits in environmental concern of non-industrial private forest owners in Sweden
Environmental benefits have become priority objectives for the management of forests, including for private forest owners in many countries. Understanding and promoting environmental-friendly private forest management requires a measure of environmental concern of forest owners and knowledge of factors that influence it. Such a measure allows to explore underlying motivations of forest owners to include environmental aspects in their forest management. This in turn helps in developing and implementing effective pro-environmental forestry policies. In this paper, we assess environmental concern in forest management of 226 non-industrial private forest (NIPF) owners in Sweden. In particular, we sought to achieve a two-fold objective: a) to quantitatively explore the content and dimensionality of the environmental concern construct of forestry owners and b) to identify the association between environmental concern of forest owners and their personal values and personality traits. A principal factor analysis resulted in a two-dimensional environmental concern construct encompassing: environmental strategy and environmental orientation. Hierarchical seemingly unrelated regressions (SUREG) showed that personal values and personality traits help to explain environmental concern in forest management of NIPF owners. A better understanding of environmental concern of forest owners and its relation with individuals' attributes will help in better designing, framing and targeting of tailor-made interventions to promote environmental considerations in forest management
Community capacity for social enterprise development : Empirical evidence from community forest enterprises (CFEs) in Cameroon
With increasing forest devolution globally, community forest enterprises (CFEs) are emerging as potential options for local development based on forest resources. CFEs trade to meet their economic, social, and environmental goals; however, empirical studies have highlighted capacity deficiencies as key drawbacks to their development. Knowledge of what these capacity gaps are is low. This paper uses a systematic framework to explore capacity and deficiencies in capacity and the relation between the two within CFEs in Cameroon. Using the contextualised organisational capacity theory in combination with asset-based mobilisation theory, data was gathered from 31 CFEs based on focus group discussions. Principal component analysis and descriptive statistics were used to evaluate community capacity at individual, organisational (CFE), and network levels. Pearson correlation tests were used to explore the relationships between different domains of community capacity. The results indicate that community members and development practitioners agree that communities are weak in creating partnerships, networking, and resource mobilisation. The participatory community evaluation highlights major capacity gaps in infrastructure, members' skills and knowledge, and sense of community. This confirms that capacity gaps were larger at the individual and social network level, while organisational capacity scored higher except for a sense of community and resource mobilization. Although the community capacities at the individual level are generally low, these capacities correlate strongly with organisational capacity. The potential of the CFEs to meet objectives depends a lot on the capacities of individual members and networking capacity, indicating that these should be prioritised in development efforts, which should involve multiple stakeholders, with policy support and participation by the entire community
Mapping future changes in livelihood security and environmental sustainability based on perceptions of small farmers in the Brazilian Amazon.
ABSTRACT Deforestation is a widely recognized problem in the Brazilian Amazon. Small farmers play a key role in this process in that they earn their livelihood by ranching and farming. Many studies have addressed the link between deforestation and livelihood strategies adopted by small farmers. Most have focused on advanced monitoring systems, simulation models, and GIS approaches to analyze the interaction of both dimensions, i.e., livelihoods and forest cover change. Although the current toolbox of methods has proved successful in increasing our understanding of these interactions, the models and approaches employed do not consider small farmers’ perspectives. On the assumption that local small farmers are agents of land-cover change, understanding how they perceive their own situation is essential to elucidate their actions. Our objective is to explore future changes in livelihood security and environmental sustainability as envisaged by local small farmers in the Brazilian Amazon. Previous livelihood cluster analysis of small farmers located in southeast Pará was integrated with fuzzy cognitive mapping to determine present perceptions and to explore future changes, using global scenarios downscaled to the local situation. Overall, system description differs only on details; all results indicate a strong trade-off between livelihood security and environmental sustainability in all livelihood systems, as identified by the small farmers. However, fundamentally different outcomes are obtained from the future analysis, depending on the livelihood strategy cluster. Achieving win-win outcomes does not necessarily imply a positive scenario, especially if small farmers are dependent on income transfers from the government to provide their livelihood

Forest biodiversity, carbon sequestration, and wood production: modeling synergies and trade-offs for ten forest landscapes across Europe
Original ResearchEurope’s forests provide vital habitat for biodiversity and essential ecosystem services
whose provision must be sustained or enhanced over the coming century. However,
the potential to secure or increase forest ecosystem services, while securing the
habitat requirements of taxa remains unclear, especially within the context of uncertain
climate and socio-economic developments. To tease out the associated trade-offs
and synergies, we used 10 case study landscapes within nine countries throughout
Europe. Starting with the current status of the forests in the case study landscapes,
we simulated forest development 100 years into the future. Simulations were embedded
in three combined climate and socio-economic frame scenarios based on global and
European policies which varied in their climate change mitigation efficiency. Scenarios
were translated into country specific projections of climate variables, and resultant
demands for wood products. Forest management regimes were projected to vary in
response to these scenarios at local scales. The specific combinations of alternative
forest management practices were based on parallel research and input from local forest
stakeholders. For each case study, a specific forest growth simulator was used. In
general, the climate scenarios applied did not cause fundamentally different ecosystem
service outputs at the case study level. Our results revealed almost no reduction in outcomes for biodiversity indicators with an increase in wood production, and in some
cases synergistic results occurred when diversity was actively promoted as part of the
management concept. Net carbon uptake was not strongly correlated with biodiversity,
indicating that biodiversity-friendly forest management doesn’t need to curtail carbon
sequestration. Notably, we obtained heterogeneous results for the relation between
sustainable wood production and net carbon uptake. Most scenarios resulted in a
more or less reduced net carbon uptake over the long term, often due to stand age
class distribution shifts. Levels of sustainable wood production varied widely during
the simulation period, from significant increases (Sweden, Lithuania) to minor changes
(Slovakia, Turkey) and slight decreases (Ireland, Netherlands). We place our results
within the larger context of European forest policy and the challenges of simulating and
contrasting forest biodiversity and the ecosystem services that societies depend on outcomes for biodiversity indicators with an increase in wood production, and in some
cases synergistic results occurred when diversity was actively promoted as part of the
management concept. Net carbon uptake was not strongly correlated with biodiversity,

Two decades of forest-related legislation changes in European countries analysed from a property rights perspective
In the last two decades, attention on forests and ownership rights has increased in different domains of international policy, particularly in relation to achieving the global sustainable development goals. This paper looks at the changes in forest-specific legislation applicable to regular productive forests, across 28 European countries. We compare the legal framework applicable in the mid-1990s with that applicable in 2015, using the Property Rights Index in Forestry (PRIF) to measure changes across time and space. The paper shows that forest owners in most western European countries already had high decision-making power in the mid-1990s, following deregulation trends from the 1980s; and for the next two decades, distribution of rights remained largely stable. For these countries, the content and direction of changes indicate that the main pressure on forest-focused legislation comes from environmental discourses (e.g. biodiversity and climate change policies). In contrast, former socialist countries in the mid-1990s gave lower decision-making powers to forest owners than in any of the Western Europe countries; over the next 20 years these show remarkable changes in management, exclusion and withdrawal rights. As a result of these changes, there is no longer a clear line between western and former socialist countries with respect to the national governance systems used to address private forest ownership. Nevertheless, with the exception of Baltic countries which have moved towards the western forest governance system, most of the former socialist countries still maintain a state-centred approach in private forest management. Overall, most of the changes we identified in the last two decades across Europe were recorded in the categories of management rights and exclusion rights. These changes reflect the general trend in European forest policies to expand and reinforce the landowners' individual rights, while preserving minimal rights for other categories of forest users; and to promote the use of financial instruments when targeting policy goals related to the environmental discourse
Оптимизация конструкции захвата для детали «Барабан»
Грузозахватные приспособления обычно применяются при производстве работ по подъему и перемещению грузов с применением грузоподъемных машин. Использование приспособлений позволяет реализовать максимальное удобство и безопасность производственного процесса. Грузозахватные приспособления конструируются для определенного этапа технологического процесса, для конкретного изделия. При проектировании таких приспособлений необходимо учитывать основные показатели оптимальности конструкции: прочность, надежность, простота, удобство и безопасность при эксплуатации, эргономичность. Кроме того, нужно стремиться к наименьшей массе и, соответственно, металлоемкости захвата. Конструкция грузозахватного приспособления, в основном, будет зависеть от назначенных технологом поверхностей, за которые можно крепиться и от максимальной высоты подъема крюка крана.
