Abstract Background Maintenance of biodiversity is an integral part of sustainable forest management. Epiphytic bryophytes are an important element of biodiversity. Thus, this work aims to study the role of different physical and biochemical factors in affecting the growth and proliferation of epiphytic liverworts. Fifty trees in three different plots, distributed in Senchal wildlife sanctuary, Darjeeling, were surveyed. Factors such as light intensity, moisture, and diameter at breast height (DBH) of the tree were studied to evaluate their possible role in affecting epiphytic liverworts. The effect of bark biochemical characteristics on the abundance of epiphytic liverworts was also studied by undertaking a quantitative test of pH, phenol, flavonoid, ortho-dihydric phenol, terpene, total sugar, and tannin. Multiple regression analysis and principal component analysis (PCA) were carried out to test the effects of these parameters. Results Light intensity, moisture, and DBH highly influenced the abundance of liverworts. Old trees had higher epiphytic liverwort cover than younger ones. Bark biochemical properties like pH, phenol, flavonoid, ortho-dihydric phenol, tannin and sugar did not have a significant effect on the epiphytic liverwort cover, while the terpenoid content of the bark reduced liverworts cover. Conclusion To sustain the occurrence of epiphytic liverworts in ecosystems, forest management should ensure the presence of old trees. Light intensity and moisture had a large effect on the distribution and abundance of liverworts, so it is important to maintain tree cover, shrub layer, and tree density.

The Village

It is essential to involve communities in the surrounding areas or buffer zones towards effective and efficient forest area management in the management of forest conservation areas. As one of the supporting villages in the Nantu-Boliyohuto Wildlife Sanctuary area, Sari Tani Village is located in the Wonosari sub-district, Boalemo Regency, which needs to be a part of a collaboration or partner in sustainable forest management. Therefore, the community's welfare in the buffer village should be a common concern as a manifestation of the vision of sustainable forest management. Accordingly, this research seeks to measure the welfare level of the community in the village. The data were generated from interviews and observations on 85 families as research samples. Those were further analyzed using descriptive, qualitative, and quantitative methods, referring to eight welfare indicator criteria based on the Central Bureau of Statistics (BPS 2016) with weighting or scoring. The results indicated that the score of the welfare indicator assessment was 13. It means that the welfare level of the Sari Tani village community was in the low category number interval. Thus, it is suggested to develop the village area as the smallest government administration area and as a buffer village for the Nantu-Boliyohuto wildlife sanctuary area using an approach to indicators that affect the level of welfare, viz. education, employment, levels and patterns of consumption, and poverty.

Resolution  H1 of the Second Ministerial Conference on the Protection of Forests in  Europe    defined sustainable forest management. Resolution L2 of the third  conference in Lisbon    adopted the Pan-European operational level guidelines for sustainable  forest management.    These guidelines are designed for sub-national applications at a practical  level. They should be    applied in the context of, and in full respect to, national and/or regional  instruments and actions.    They are directly based on the resolutions H1 and H2 and they follow the  structure of the six    pan-European criteria that were identified as the core elements of  sustainable forest    management.    The paper implements the six criteria by proposing and developing for each  criteria a number of    key issues that should be kept in mind for the realization of sustainable  forestry at the field level.    Altogether, 39 items are presented, such as forest maintenance,  profitability, exploitation    techniques, enhancement of biodiversity, native tree species, dead wood and  old trees,    participation, etc.    The major problem remains the assessment of sustainable forest management.  There is a lack    of knowledge. Sustainable forest management requires that no big  shortcomings on a large    area occur for each of the criteria. Sustainable forest management is a  process of continuous    improvement.

State Forest Management Organizations (SFMOs) play a crucial role in the European forest sector, managing almost half the forests in the region. SFMOs are often managed for timber production only whereas, being publicly owned, they should play an important role in providing a vast range of public goods (e.g. soil protection, biodiversity conservation). Their management goals depend on the history and current conditions of the forest sector at a national level, as well as different challenges and the potential for development. Although there is a lack of knowledge about the current performance of SFMOs, there have been recent changes to their management goals and practices in response to the new demands expressed by society (e.g. transparency, social inclusion). The main purpose of this study is to analyse the current situation of SFMOs by clustering them according to indicators that reflect three pillars of the common understanding of sustainable forest management (SFM) concept. With the help of Principal Component Analysis (PCA), we grouped countries according to common characteristics of the forest sector at the national level. Results show three main clusters of SFMOs in Europe. The first cluster has rather small but commercially-oriented forestry unit together with other business activities and a strong focus on public services. The second sees itself as the protector of public interest, rather than commercially-oriented organisations. The third is mainly profit-seeking. The existence of diverse SFMO clusters shows the possibility of different approaches for SFM with a focus on different goals (e.g. profit gaining, public service delivery).

Despite substantial investments in high-frequency, remote-sensed forest monitoring in the Amazon, early deforestation alerts generated by these systems rarely reach the most directly affected populations in time to deter deforestation. We study a community monitoring program that facilitated transfer of early deforestation alerts from the Global Forest Watch network to indigenous communities in the Peruvian Amazon and trained and incentivized community members to patrol forests in response to those alerts. The program was randomly assigned to 39 of 76 communities. The results from our analysis suggest that the program reduced tree cover loss, but the estimated effects from the experiment are imprecise: We estimate a reduction of 8.4 ha per community in the first year (95% CI [−19.4, 2.6]) and 3.3 ha in the second year (95% CI: [−13.6, 7.0]) of monitoring. The estimated reductions were largest in communities facing the largest threats. Data from monitoring records and community surveys provide evidence about how the program may affect forest outcomes. Community members perceived that the program’s monitors were new authorities with influence over forest management and that the monitors’ incentivized patrols were substitutes for traditional, unincentivized citizen patrols that suffer from free riding and inhibit timely community detection of and responses to deforestation. Should our findings be replicated elsewhere, they imply that externally facilitated community-based monitoring protocols that combine remote-sensed early deforestation alerts with training and incentives for monitors could contribute to sustainable forest management.

Os custos da exploração de lenha representam o principal componente de custos no manejo florestal sustentável da Caatinga e influenciam diretamente a viabilidade econômica da atividade. Assim, objetivou-se com este trabalho analisar tecnicamente e estimar os custos de dois sistemas de exploração de lenha da Caatinga no estado do Rio Grande do Norte, um manual (com machado e foice) e outro semimecanizado (com motosserra), e determinar a participação dos custos de exploração no custo total da lenha em áreas com manejo florestal. A coleta de dados foi realizada por meio de estudo de tempos e movimentos, com a cronometragem pelo método de tempo contínuo. No sistema semimecanizado, a jornada de trabalho foi inferior (30%) e o tempo de pausas foi menor (49%) em relação ao manual, evidenciando a vantagem do uso de motosserra para os trabalhadores. A produtividade média também foi maior no sistema semimecanizado (1,32 st.he-1) do que no manual (0,78 st.he-1). Contudo, a exploração semimecanizada resultou num maior custo de produção (R$ 14,44.st-1) do que a manual (R$ 11,17.st-1). As atividades de exploração tiveram maior incidência sobre o custo total da lenha, representando 66% no sistema manual e 83% no sistema semimecanizado.Palavra-chave: energia, manejo florestal sustentável, região Nordeste. PRODUCTIVITY AND COSTS OF TWO LOOGING SYSTEMS AND FIREWOOD TRANSPORTATION IN CAATINGA DRY FOREST  ABSTRACT:Firewood logging costs represent the highest cost component of sustainable forest management of Caatinga dry forest and they directly influence the economic viability of the activity. Thus, this study aimed to analyze technically and estimate the costs of two firewood logging systems in Caatinga dry forest, one manual (with ax and sickle) and other semi-mechanized (with chain saw), and determine the share of these costs in the total cost of firewood in areas with forest management plan. Data collection was based on time and motion study. In the semi-mechanized system, the working journey was shorter (30%) and the break time was lower (49%), showing the advantage of using chainsaws for workers. The average productivity was also higher in semi-mechanized system (1.32 st.h-1) than the manual (0.78 st.h-1). However, the semi-mechanized logging resulted in higher production costs (R$ 14.44.st-1) than the manual (R$ 11.17.st-1). Logging was the principal component of the total cost of firewood, representing 66% in manual system and 83% in semi-mechanized system.Keywords: energy, sustainable forest management, Northeast region of Brazil. DOI:

The implementation of todays forest management that based on formal-scientific knowledge and technical knowledge seems to fail to protect the forest from deforestation and the environmental damage. Decolonialisation of western knowledge could give an opportunity to identify and find the knowledge and practices of indigenous people in sustainable forest management. Forest management based on the indigenous knowledge and practices is believed easy to be accepted by the indigenous community due to the knowledge and practice is known and ‘lived’ by them. The Atoni Pah Meto from West Timor has their own customary law in forest management that is knows as Bunuk. In the installation of Bunuk, there is a concencus among the community members to protect and preserve the forest through the vow to the supreme one, the ruler of the earth and the ancestors, thus, bunuk is becoming a le’u (sacred). Thus, the Atoni Meto will not break the bunuk due to the secredness. Adapting the bunuk to the modern forest management in the Atoni Meto areas could be one of the best options in protecting and preserving the forest.

The Impact

Are there any common patterns in the transition processes from traditional and more or less sustainable forest management to exploitative use, which can regularly be observed both in central Europe and in the countries of the South (e.g. India or Indonesia)? Attempts were made with a time-space-model to typify those force fields, in which traditional sustainable forest management is undermined and is then transformed into a modern type of sustainable forest management. Although it is unlikely that the history of the North will become the future of the South, the glimpse into the northern past offers a useful starting point for the understanding of the current situation in the South, which in turn could stimulate the debate on development. For instance, the patterns which stand behind the conflicts on forest use in the Himalayas are very similar to the conflicts in the Alps. In the same way, the impact of socio-economic changes on the environment – key word ‹globalisation› – is often much the same. To recognize comparable patterns can be very valuable because it can act as a stimulant for the search of political, legal and technical solutions adapted to a specific situation. For the global community the realization of the way political-economic alliances work at the head of the ‹globalisationwave›can only signify to carry on trying to find a common language and understanding at the negotiation tables. On the lee side of the destructive breaker it is necessary to conserve and care for what survived. As it was the case in Switzerland these forest islands could once become the germination points for the genesis of a cultural landscape, where close-to-nature managed forests will constitute an essential element.
