Nowadays, most of teak wood that available on the market was mainly from comunity forest. Those teak woods were commonly harvested in the early age. The young teak wood from community forests possesses lower proportion of heartwood than sapwood. Those condition was generally had an affect on the wood durability. Although the wood durability was estimated to be low, but the teak wood from community forest was intensively used for furniture and house construction. Therefore, study on the sapwood durability of young teak wood from community forest is necessary. In the present study, the durability of sapwood treated by boron compound (boric acid and borax) as wood preservatives was investigated. The boron concentrations were 5, 7 and 10%. The vacuum process were used to impreg the preservative into the wood specimens called as Lowry method. The efectivity of preservation method were investigated, namely absorption, retention, penetration, efficacy of subterranean and dry-wood termites. The absorption, retention, and penetration of boron compound were 69.10–96.41 kg/m3, 4.53–5.31 kg/m3, and 3.04–3.16 mm, respectively. Absorption, retention, and penetration of preservatives showed an increasing value by increasing the preservatives concentrations, with the highest values were obtained for 10% boron concentration. Graveyard test was used to evaluate the efficacy of boron in teak sapwood to subterranean termites. During 2 months observation, mass loss and degree of wood damage were 0.42-1.37% and 6.31-18.72%. Furthermore, the efficacy of boron was also conducted for dry-wood termites. The mass loss, degree of wood damage, and dry-wood termites mortality after 28 days observation were 1.46-1.67%, 29.45-32.38%, and 87.33-95.33%, respectively. The durability of boron treatened teak sapwood against subterranean and dry-wood termites was increased. The increasing of teak sapwood durability was characterized by reduction of mass loss and degree of wood damage compared to untreated teak sapwood (control).

Kayu jati telah digunakan untuk bermacam produk karena sifat ketahanan alami di atas rata-rata serta keindahan serat dan warna kayunya. Meski demikian, terdapat variasi untuk sifat ketahanan alami di antara pohon yang tumbuh di tempat tumbuh yang berbeda. Penelitian sebelumnya telah mendeskripsikan sifat kimia kayu jati tumbuh di zona ekologis yang berbeda (Nglipar, Panggang, dan Playen). Sebagai lanjutan, penelitian ini bertujuan menentukan sifat ketahahan alami terhadap rayap pada kayu jati yang tumbuh di hutan rakyat Gunungkidul dan mengeksplorasi faktor yang berkorelasi terhadap sifat tersebut yaitu sifat kimia dan warna kayu. Tujuan lainnya adalah membandingkan data yang diperoleh dengan data kayu yang tumbuh di hutan tanaman Perhutani (Randulatung). Uji pengumpanan tanpa pilihan menggunakan rayap tanah Coptotermes curvignathus terhadap sampel kayu dari tiga tempat tumbuh tersebut. Sifat warna tiap sampel diukur dengan sistem diukur menggunakan sistem CIELAB(L*, a*, b*). Data sifat kimia dan warna kemudian dihubungkan dengan kehilangan berat dan persen hidup rayap setelah 13 hari pengumpanan. Kayu gubal dan teras dari semua pohon menunjukkan aktivitas anti rayap. Perbedaan nyata diamati dalam persen hidup dalam interaksi faktor tempat tumbuh dan arah radial pohon. Sampel dari Panggang menunjukkan ketahanan alami yang lebih tinggi didasarkan persen hidup rayapnya. Selanjutnya, bagian teras dari sampel Playen dan Panggang menunjukkan aktivitas anti rayap yang lebih tinggi dibandingkan sampel dari Randublatung. Pengukuran warna menghasilkan tidak adanya beda nyata untuk kecerahan (L*) antara teras bagian luar dan dalam. Berdasar tempat tumbuhnya, sampel Playen memberikan warna kayu yang paling cerah. Apabila data di bagian teras dan gubal digabungkan, nilai kehilangan berat berhubungan positif dengan nilai kelarutan dalam air panas serta nilai kehilangan berat berhubungan negatif dengan nilai kadar ekstraktif etanol-toluena. Selain itu, nilai pH berkorelasi secara moderat dengan persen hidup rayap selama 8 hari pengamatan. Untuk sifat warna, diamati nilai kemerahan (a*) yang semakin tinggi diiringi oleh kenaikan kehilangan berat di bagian teras. Study of Teakwood Quality from Community Forests in Gunungkidul. VII. Natural Subterranean Termite ResistanceAbstractTeak wood has been used for various uses because of its excellent natural durability as well as beautiful grain and colour of its heartwood. However, variability in natural durability exists between trees of different geographical zones. The previous paper in this series reported on the chemical properties of teak wood from different zones (Nglipar, Panggang, and Playen). In this study, as a continuation, natural termite resistance of teak wood grown in community forests of Gunungkidul and the factors correlating to the termite resistance i.e. chemical and colour properties, were determined. Further, the data obtained here were compared with that of wood samples from Perhutani forest plantation (Randublatung site). No-choice termite feeding test by using a subterranean termite Coptotermes curvignathus were conducted on wood samples taken from three trees of three planted sites. The colour properties of each sample were measured using the CIELAB (L*, a*, b*) system. The chemical and colour characteristics results then were correlated with the mass loss of wood and survival rate of termites after 13 days of feeding. The heartwood and sapwood of all of the trees tested exhibited antitermitic activities. Significant differences were found in survival rate of termites due to interaction of the site and radial position. Samples from Panggang had larger termite resistance judging by its survival rate of termites. Further, the heartwood regions of Panggang and Playen sites exhibited higher antitermite activities than those of Randublatung samples. Measurements of colour showed that no significant differences were found between outer and inner heartwood parts. Samples from Playen showed the lightest on the basis of the sites. In the combined sapwood and heartwood data, mass loss was positively associated with hot-water solubility levels and negatively with ethanol-toluene extractive content. In addition, pH values moderately correlated with survival rate on 8-day observation. With regard to colour properties, it was measured that larger a* values (redness) induced larger mass loss of heartwood.

Forest management in terms of its production function is directed towards management that is oriented towards all potential forestry resources and is based on community empowerment. The Wana Tekat Mandiri Farmer Group Association manages community forests, namely state forests whose main use is aimed at empowering the community. The rampant illegal logging is carried out by irresponsible parties outside of the farmer group association. So that community groups that carry out illegal logging do not support the Regional Government in providing guidance to the Association of Farmer groups in the Sendang Agung District area. The type of research used in this research is descriptive type with a qualitative approach, data collection techniques, observation, interviews, documentation. The results of this study indicate that the strategy of community development and empowerment in community forest utilization has been running well and the implementation of the strategy has been deemed successful in implementation. The coaching strategy has a main objective in the framework of developing a coaching plan in carrying out activities or programs of Gapoktan Wana Tekad Mandiri, namely by how to develop skills, develop knowledge and develop attitudes. The existence of this coaching strategy is expected to have a good empowering impact on the community.

In spite of the widely accepted success of Community Forestry in reviving degraded land, it is still seen as being unable to provide tangible benefits to the poor. This paper illustrates that through continuous sharing, deliberation and negotiation among the poor and non?poor members of Community Forest User Groups (CFUGs), management of community forests can be made far more equitable than the usual scenario. Drawing from the experience on the processes and outcomes of Livelihoods and Forestry Programme (LFP), this paper brings empirical evidence of how facilitation support has enabled the poor to have more equitable access to community forests. Three key pro?poor institutional arrangements resulting from the facilitation process include: a) establishing special use rights arrangements within CFUGs for the poor, b) pro?poor silvicultural practices, and c) equitable forest product and benefit distribution mechanisms. The paper suggests some changes in policy and practice to institutionalise these outcomes.

Forest Stewardship

In June 1997, we visited the Magnifica Comunità di Fiemme (MCF), a community forest in the Alps of northern Italy. We have prepared this article to help broaden the perspectives of Forestry Chronicle readers on community forests and what they mean in various parts of the world. We first describe the area and its forests, and then give a brief history of the MCF. Then we review the forest-management strategies used in this Norway spruce forest, and summarize the logging and wood-processing activities of the enterprise. We continue with a comparison of this community forest with three community forests in Canada, concluding that generalization on what makes a community forest successful is dangerous — each situation is unique. Finally, given that the MCF recently won permission to use the eco-label of the Forest Stewardship Council (FSC), we discuss our perceptions of how the MCF operation does and does not meet the FSC's Principles and Criteria of Forest Stewardship. Despite several shortcomings, we believe that the MCF is in most respects a sound example of sustainable forest management.

We explore local people’s perspectives of community forest (CF) on their land in Tanzania and Bolivia. Community forest management is known to improve ecological conditions of forests, but is more variable in its social outcomes. Understanding communities’ experience of community forestry and the potential benefits and burdens its formation may place on a community will likely help in predicting its sustainability as a forest and land management model. Six villages, two in Tanzania and four in Bolivia, were selected based on the presence of community forestry in varying stages. We found that communities were generally supportive of existing community forests but cautious of their expansion. Deeper explorations of this response using ethnographic research methods reveal that an increase in community forest area is associated with increasing opportunity costs and constraints on agricultural land use, but not an increase in benefits. Furthermore, community forests give rise to a series of intra- and inter-community conflicts, often pertaining to the financial benefits stemming from the forests (distribution issues), perceived unfairness and weakness in decision–making processes (procedure/participation), and also tensions over cultural identity issues (recognition). Our findings suggest that communities’ willingness to accept community forests requires a broader consideration of the multifunctional landscape in which it is embedded, as well as an engagement with the justice tensions such an intervention inevitably creates.

Perceived Change

Climate change has negatively impacted the underdeveloped and developing countries including Nepal due to low adaptive capacity and higher dependency in agriculture. Forests are important component of the lives and livelihoods of the community in Nepal, which can offer an important source of climate-resilient livelihood. It is crucial to know the fact that climate change was in the past, which will continue to change in the future. It is essential to understand how communities perceive and adapt to climate change. A study was carried out in Kirepani, Jagreni and Kalika Community Forest User Groups (CFUGs) in Lamjung District with an objective of assessing their perceptions on impacts of climate change. The survey was carried out in 62 households along with participatory appraisal to understand the perception of local people on climate change and its impacts. Focus group discussion was held in each CFUG. Climatic data of 29 years (1987–2015) acquired from Khudi, Kuncha and Gharedgunga metereological stations and analysed to supplement the results. Data were analysed using MS-Excel as major computer software and presented as table, trend lines and graphs. The study showed that the locals correctly perceived change in temperature, unpredictable occurrence of rainfall and increased incidence of change in crops phenology, an increase in drought. Based on the perceptions of the community forest users, climate change has affected the biodiversity and societal system differentially. Drought has higher impact to the people affecting their lives and livelihoods. They perceived that the increase in drought, floods, landslide have affected their lives and livelihoods. The results revealed that minimum temperature was increased at the rate of 0.01º C per year whereas the maximum temperature was increased by 0.056° C per year. From the rainfall data of Khudi meteorological station, it was found that annual rainfall was highly decreased at the rate of 25.8 mm per year, which alarms for more disaster such as drought and fire in the area. Our findings suggest that for the innovative climate change adaptation planning and policy it is crucial to incorporate and acknowledge the role of community forest in climate change adaptation.

Using Data

The last three decades have witnessed shifts in forest governance in favour of more inclusive approaches. In Uganda, two main approaches have been embraced in the forest sector: collaborative forest management and community forest management. However, there is scanty empirical evidence on how the latter has affected the forest condition over time. Using data from two bio-physical surveys (2006 and 2016) and Key Informant Interviews, this study examined changes in vegetation characteristics in two de facto community forests (Ongo and Alimugonza) over a 10-year period. The basal area and stem densities of tree species locally preferred for poles and charcoal declined in both forests due to extractive uses, some of which were illegal. The densities of those preferred for timber increased as a result of their heightened protection by the community members. However, the community members still faced challenges of apprehending rulebreakers due to the high costs involved and their informal recognition as responsible bodies since the two forests have not yet been declared "community forests" as required by law. The gains made by the approach amidst these challenges demonstrate its potential to achieve conservation goals.

Potential Analysis of Community Forests in Supporting Kuningan Regency as a Conservation Regency Kuningan Regency, as one of the conservation regencies in Indonesia, has not been able to produce timber on a large scale because its forest area is dominated by conservation and limited production forest. This has caused the production of timber from the forest area in Kuningan Regency not been able to fulfill market demands. As a result, timber from community forests became an alternative to fulfill those demands. Community forest is forest that grows on land that is burdened with ownership rights of minimum 0.25 ha and canopy cover of minimum 50%, and/or having at least 500 stems/ha in the first year. As the demand for community timber increases, in the long term, the community forest management needs good planning to support the conservation regency policy. Therefore, objectives of this research are (1) to identify the types of community forest timber based on farmers' preferences and the financial feasibility, (2) to analyze land suitability and availability, (3) to analyze the leading commodity, and (4) to suggest the direction of the development regions. Methods of this research are AHP and TOPSIS, financial feasibility calculation (IRR, BC Ratio, NPV), land suitability analysis with matching criteria as well as GIS analysis, LQ, and SSA, together with descriptive analysis. Results showed that the leading types of timber were sengon, mahogany, africa, and teak. All were feasible to be cultivated with the recommended pattern, which was agroforestry. There are 12 districts with community forests as their leading sector, namely Ciawigebang, Cigandamekar, Cimahi, Cipicung, Ciwaru, Darma, Garawangi, Japara, Kramatmulya, Lebakwangi, Luragung, and Nusaherang district. The suggestion for direction of the development regions by type is for the north and east regions to be prioritized for sengon, teak, and africa, while the west and south regions to be prioritized for mahogany.
