We identified the main impacts, drivers, and restoration projects for Atlantic Forest in Northwest of the Rio Grande do Sul State, Brazil. The objective was to analyze the quantity, distribution, and causes of the environmental crimes in 2000-2014. To verify differences between degraded and restored areas, we performed a t-test; ANOVA for the municipalities with more quantity of crimes, simple linear regression analysis for the relationship between sizes of degraded areas and quantity of seedlings planted, and Principal Component Analysis (PCA) for environmental damages categories and population of the municipalities. The main environmental damages found were deforestation outside permanent preservation area (20%) and those related to Permanent Preservation Area (37%). Environmental crimes in these areas fall into two categories: native and exotic vegetation removal (17%), and impediment to natural regeneration (20%). The average size of the degraded areas was $5,359{\pm}526m^2$, while for restored areas was $3,337{\pm}255m^2$. The sizes of the degraded fragments were similar among the five municipalities with the higher number of environmental crimes (ANOVA: p>0.05, F=1.24; df=241). The number of seedlings planted was positively related to the sizes of the degraded fragments (p<0.001, $R^2=0.53$). Segregation between the less and the most populous municipalities was found with the PCA analysis along PC1 (51.7%), while PC2 represented 19.2% of the total variation. The most populous municipalities showed the highest number of environmental crimes, and the majority of degraded areas were recovered by planting native seedlings. Atlantic Forest fragments need to be recognized and preserved as an ecosystem with a unique ecological function by the population and public administration.

Forestry education in vocational high schools is one of the fundamental keys for achieving sustainable forest management. However, support systems for forestry education have not been well developed in Japan. Forest research institutes, which have accumulated relevant information, should have sufficient ability to develop new educational programs in this field. This study examined the possibility of support systems for forestry technical education by a research institute. Educational programs for vocational high schools were developed, and the programs were examined for their practical applications through a workshop for these teachers. We set the following five requirements for the programs: They should 1) incorporate new contents related to sustainable forest management, 2) be based on forestry education textbooks, 3) meet recent demands of the schools and society, 4) allow participants to learn through actual practice and experience, and 5) utilize readily available teaching materials. With these criteria, we developed the following two educational programs: (a) Forest management program to teach advanced techniques, (b) A timber-program to teach about biomass resources. The workshop was held on July $28^{th}$, 2007 with ten teachers attending. The programs were very interesting, who gave them high average evaluation of 4.6 on a scale of 1 to 5. Only a few issues need to be resolved before classroom instruction can begin, such as making wood structure easier to understanding for some teachers, and obtaining base maps of school forests. In conclusion, forest research institutes can effectively support forestry education by providing and implementing programs based on scientific information.

지속가능발전목표(Sustainable Development Goals, SDGs)라는 범지구적 이슈가 등장하면서 유엔산림포럼(UN Forum on Forests, UNFF)은 산림부문의 기여 가능성을 강조하고 장기 전략을 수립하는 등 큰 진전을 보였다. 2030년까지 산림과 관련된 국제협약 및 국제회의에서 논의의 주축이 될 SDGs 이행과 관련하여 종합 정보체계를 구축하고 통합적인 조정자 역할을 하는 등 그 역할이 주목받고 있다. 따라서 본 연구에서는 최근 UNFF의 논의 동향을 검토하는 한편 UNFF에서 수립한 유엔산림전략계획(United Nations Strategic Plan for Forest, UNSPF)의 의미를 확인하였다. 이를 통해 국내에서도 지속가능발전을 위한 산림부문의 논의가 활성화되고 UNFF의 장기전략(UNSPF)과 글로벌산림목표(Global Forest Goals, GFGs)가 효과적으로 이행될 수 있도록 다음의 세 가지 정책적 제언을 제시하고자 한다. 첫째, 산림부문의 논의를 활성화하기 위하여 부문, 기관, 국가 간 협력이 무엇보다 중요하다. 둘째, 실제 임업 현장에서도 산림부문의 역할과 기여에 대한 인식과 이해가 고취되고 이를 바탕으로 한 국내정책과 목표가 수립되어야 한다. 셋째, UNSPF 이행을 점검하기 위한 UNFF 보고서를 적극적으로 활용하여 합리적 보고체계를 마련함과 동시에 다양한 목표의 국가보고 간 중복성을 검토하는 등 보다 효율적인 보고체계를 마련해야 한다.

This study investigated the reference case in the UK where legality and sustainability were systematically established for forest biomass represented by wood pellets. The UK is the country that best utilizes the trade value of wood pellets based on sustainability, with bioenergy accounting for 31% of total renewable energy production. The UK imported wood pellet, estimated 8,697 thousand tons in 2019. The UK government has continuously improved the renewable generation policy system to ensure the sustainability of wood pellets. The weighted average greenhouse gas emissions of a UK biomass power plant that received a Renewable Obligation Certificate (ROC) in 2018-19 was 26.71 gCO2e/MJ. These power plants are expected to meet the upper limit of 72.2 gCO2e/MJ by 2025. To issue an ROC, the biomass power plant must demonstrate that 70% of its total biofuel usage is sustainable. The UK uses the Sustainable Biomass Program (SBP) certification system, which is gradually expanding to other European countries, to prove the sustainability of biomass energy fuels. Global wood pellet production with SBP certification in 2019 was 10.5 Mt. This trend has significant implications for introducing additional sustainability into the wood pellet policy of South Korea.

Malaysia possesses about 1.56 million ha of Peat Swamp Forest (PSF). The PSF safeguard enormous biological diversity, while providing crucial benefits for the sustainable development of human communities. Numbers of threatened plant species are associated with the PSF, including the commercially important Gonystylus bancanus timber. To prevent significant losses of biodiversity, it is important to manage the PSF for both biological conservation and sustainable use. Equally important is to restore all degraded PSF in an attempt to ensure the PSF ecosystem is suitable for the vegetation to grow and rehabilitate back to the normal condition. Prior to plan any forest restoration program, there is a need to properly map the degraded PSF in order to estimate the forest conditions and determine the vegetations status. Most of the time this need to be done at a landscape level and requires a technology that can provide accurate, timely and reliable information for the planner to make decision. This paper describes a study using geospatial technology in combination with ground survey to classify the degraded PSF in South East Pahang Peat Swamp Forest (SEPPSF), Malaysia, into different degree of vegetation classes. With map accuracy of about 83%, the technique proved to be useful in delineating the different degree of PSF degradation from which the information can be used to properly plan forest restoration program in the area. The final output which is in the form of map can be used in developing a Restoration Master Plan for the degraded PSF areas.

Total forest land in Bangladesh is about 2.5 million hectare which is 17% of total land area. Bangladeshi forest is mainly classified into three categories- 1) Hill forest 2) Sal forest and 3) Mangroves. This forest land area is decreasing day by day. But in past decayed due to some policies, the total forest land area is increasing slowly. By this planning both government and the local people in the community are being benefited. This paper mainly discussed about the past, present and future trend of forest condition, forest land uses, sustainable forest planning and forest management.

This study concentrates on the trail of the CNU(Chungnam National University) forest. The amount of use and the pattern of damage are considered, as well as the extent of environmental damage. Finally, some managerial strategies are proposed in connection with sustainable maintenance. The trail of the university forest is composed of three sections; one is the neighborhood park and the Institute of Information Technology/Communications, the second is the Institute of Information Technology/Communications and the Dormitory, and the third section is the Dormitory and the Foreign prof's Apt. The total length of the trail is 2.6km. The daily amount of use is 1,269 visitors per day. The amount of using increased three times the amount of that in 1998. This study shows the pattern of damage of the trail in the order of root-exposure, widening, rock-exposure, deepening and the divergence in the frequency of occurrence of all these factors. Environmental damage is also graded thus: grade 3 is 27.4m, grade 4 is 0.8m, grade 5 is 1.5m, and grade 6 is 0.2m. Accordingly, some managerial strategies were proposed in connection with the sustainable trail maintenance.

본고에서는 기후변화와 산림생장, 수종변화, 탄소저장, 임목고사 간의 관계에 대한 연구들을 소개하고, 기후변화 대응을 위한 관리 전략을 제언하고자 한다. 1) 산림생장측면에서 보면, 소나무를 포함한 우리나라 주요 침엽수종들의 생장은 기온과 음의 상관관계를, 굴참나무와 신갈나무를 포함한 낙엽성 참나무류는 양의 상관관계를 갖는 것으로 나타났다. 2) 수종분포 측면에서 보면, 다양한 모델에서 동일하게 중 장기적으로 기후변화의 영향으로 인해 침엽수림의 분포가 감소하고, 참나무류의 분포가 증가할 것으로 예측되었다. 3) 탄소저장량 측면에서는 산림관리 여부에 따라 예측 결과에 큰 차이가 있었다. 우리나라 산림은 2030년 이후에 대부분 노령림으로 성숙되며, 현재 벌기령을 유지하여 주벌과 재조림을 실시할 경우 2090년까지 약 4.1억 톤의 산림바이오매스를 생산할 수 있을 것으로 추정되었다. 4) 임목고사 측면에서 보면, 우리나라 주요 침엽수종들은 기온이 높은 곳에서 고사율이 증가하는 경향이 뚜렷하게 나타났으며, 반대로 참나무류는 고사율이 감소하는 것으로 나타났으나 통계적인 유의성은 검증되지 않았다. 또한, 기후변화에 의해 아고산 침엽수종들의 고사가 급격하게 진행될 것으로 예측되었다. 위의 영향들을 종합적으로 고려하였을 때, 먼저 상대적으로 기후변화에 취약한 침엽수림에 대한 관리전략이 필요한 것으로 사료된다. 또한, SDGs, 생태계서비스, 탄소역배출 등의 국제적 이슈와 연계시켜 지속가능한 산림계획을 생태계서비스 및 탄소흡수 저장 측면에서 수립 및 이행해야 할 것이다.
