After the implementation of Law Number 23/2014 on Regional Government in Indonesia, the authority for forest management rests with the central and provincial governments. This study aims to (1) assess forest governance performance after the implementation of this law, (2) analyse the institutional aspects of forest governance after the implementation of this law and (3) formulate strategies to strengthen forest governance institutions. This study finds that although Law Number 23/2014 has been implemented in North Sumatra Province, the forestry sector remains centralistic; the characteristics of forest resources have not changed (these continue to be common pool resources) and the behaviour of the actors lacks synergy. In this scenario, the performance of forest governance has not improved significantly, as indicated by the incomplete designation of forest areas; the number of Kesatuan Pengelolaan Hutan that have not implemented the Badan Layanan Umum Daerah scheme; the low rights of access and low forest utilisation by the community; and the slow service process for permits; however, the costs for obtaining permits are according to regulations. This is in line with the results of this study’s institutional analysis, which show that (1) the provincial jurisdiction boundaries have narrowed, given that only the central government has authority over the forestry planning sub-function and forestry supervision; (2) many central government regulations continue to be used in forest management, characterising the low aspect of provincial regional representation rules; and (3) despite clear forest ownership rights, there are claims from other stakeholders, which indicates the low legitimacy of the parties. This study suggests that forest governance performance can be improved by expanding the jurisdiction boundaries through the assistance task mechanism to the provincial government; ensuring provincial government participation in formulating forest policies; and increasing the status of forest permit holders and managers from claimants to proprietors.
在印度尼西亚实施关于区域政府的第23/2014号法律后,森林管理权归中央和省级政府所有。本研究旨在(1)评估该法实施后的森林治理绩效;(2)分析该法实施后森林治理的制度方面;(3)制定加强森林治理制度的战略。本研究发现,尽管第23/2014号法律已在北苏门答腊省实施,但林业部门仍然是中央集权的;森林资源的特点没有改变(这些仍然是共同资源池),行动者的行为缺乏协同作用。在这种情况下,森林治理的绩效没有显著改善,如森林地区的指定不完整;尚未执行巴丹拉亚南Umum Daerah计划的Kesatuan Pengelolaan Hutan的数目;社区的采伐权低,森林利用率低;许可证办理过程缓慢;然而,获得许可证的费用是根据规定的。这与本研究的制度分析结果一致,结果表明:(1)由于林业规划子职能和林业监督职能仅由中央政府管辖,省级管辖范围缩小;(2)许多中央政府法规在森林管理中继续使用,省级区域代表规则的特点较低;(3)尽管森林所有权明确,但仍有其他利益相关者提出要求,这表明各方的合法性较低。研究表明,通过对省级政府的援助任务机制,扩大管辖范围可以提高森林治理绩效;确保省级政府参与制定森林政策;并提高森林许可证持有人和管理者的地位,从索赔人到所有者。

This research examines models of social resistances in response to top-down forest governance in the provincial government of East Nusa Tenggara Province,  Indonesia. The researcher demonstrates the models of (1) forest management and (2) people’s resistance against the regional government.The author found three fundamental problems through the perspectives of the right to the governing authority of the state and social resistance. First, the provincial government monopolise forest management since 1982 for cattle breeding.  Instead of offering prosperity to the people, this forest management model excludes the people from the forest and cattle resources. Second, when the signed contract ended, the local residents refused to extend forest management concessions to the provincial government. Third, the refusal by the residents was carried out through various forms of social movements and cultural politics. However, the provincial government mobilised the police, the civil service police, and the armed forces to intimidate the resistant communities.
本研究考察了印度尼西亚东努沙登加拉省省政府对自上而下的森林治理的社会抵抗模式。研究人员展示了(1)森林管理和(2)人民反抗地方政府的模式。作者通过对国家统治权和社会反抗的视角,发现了三个根本性的问题。首先,自1982年以来,省政府垄断了养牛的森林经营。这种森林经营模式没有给人民带来富裕,而是把人民排除在森林和牲畜资源之外。第二,当签订的合同结束时,当地居民拒绝将森林经营特许权延长给省政府。第三,居民的拒绝是通过各种形式的社会运动和文化政治进行的。然而,省政府动员了警察、公务员警察和武装部队来恐吓抵抗的社区。

Wildlife trade has become one of the main causes of species loss and extinction. Increasing anthropogenic pressure posits crucial challenges to wildlife, and several species are threatened or at the edge of extinction. In this study, we aimed to examine the current wildlife trade in Makassar City of South Sulawesi, especially focusing on traded species, their area of origin, price, conservation status and traders’ distribution across the city. We conducted a market survey and direct observations of animals and wildlife traders in several locations, using a questionnaire targeting both wildlife/pet sellers and buyers. We also interviewed government bodies related with wildlife trade. Our results showed that there were 13 distribution spots of wildlife trading in the city of Makassar, and 27 different wildlife suppliers. During the seven months of observation (March-September 2018), the trade involved 62 species of birds, mammals and reptiles. More than 50% of these species had Indonesian origins, and 18% were endemic species of Sulawesi Island. The highest number of animals traded in the market were birds. Out of the 2,642 individuals being traded, 32 were considered as protected species under the IUCN regulation, 24 were species whose trade is regulated by CITES, and 10 were nationally protected according to the Indonesian Government’s Laws. The traded animals were obtained from different sources, including direct hunters, middlemen, opportunists, and breeders, mostly from Sulawesi (44.19%) and western parts of Indonesia (37.21%).
野生动物贸易已成为物种丧失和灭绝的主要原因之一。不断增加的人为压力对野生动物构成了重大挑战,一些物种受到威胁或濒临灭绝。在本研究中,我们旨在研究南苏拉威西望加锡市野生动物贸易的现状,特别是关注交易物种,它们的原产地,价格,保护状况和贸易商在全市的分布。我们对几个地点的动物和野生动物贸易商进行了市场调查和直接观察,使用了针对野生动物/宠物卖家和买家的问卷调查。我们还采访了与野生动物贸易有关的政府机构。结果表明,望加锡市共有13个野生动物交易点,27个不同的野生动物供应商。在7个月的观察期间(2018年3月至9月),该贸易涉及62种鸟类、哺乳动物和爬行动物。其中50%以上为印度尼西亚原产种,18%为苏拉威西岛特有种。在市场上交易的动物数量最多的是鸟类。在2,642只被交易的物种中,32只被IUCN视为受保护物种,24只受CITES管制,10只受印尼政府法律保护。交易的动物来自不同的来源,包括直接猎人、中间商、机会主义者和饲养者,主要来自苏拉威西岛(44.19%)和印度尼西亚西部(37.21%)。

Forest ecosystems are depleting and heading towards degradation which would adversely affect the world's socio-economic harmony. Various disasters disturb the cordial relationship of the flora and fauna and impose imbalance in the ecology as a whole; forest fire is one of its kind. India has witnessed a 125% rise in forest fire occurrences between the years 2015 and 2017. This paper presents a study of various factors and the analysis of forest fire in Sikkim. The period of 10 years, forest fire incidences, i.e., from the year 2004 to the year 2014 have been considered for the study. The forest fire data was collected from Forest and Environment Department, Government of Sikkim, and preliminary processing was performed to check for anomalies. The study observed that there has been an increased forest fire incidence over the years and highest being in the year 2009. These fire incidences have damaged a total area of 5,047.16 ha of land damaging various flora and fauna. It was observed that the maximum forest fire cases are below an altitude of 1500m, during winter months (December to February extending to March) and in sub-tropical Sal (Shorea robusta) forest. West district of Sikkim recorded the highest number of forest fire incidences and area covered followed by south and east districts; the north district was least affected. As per the visual interpretation of forest fire incidence data and literature review, the main factors responsible for forest fire in Sikkim are low rainfall, dry winter season, and type of vegetation. Also, a linear regression was performed between weather factors like average temperature (°C), relative humidity (%), and wind velocity (Km/h) on incidences of forest fire between the year 2009-2014 (n=389). It was found that the average temperature (r=0.37, Slope=9.59 and SD= ±12.00) and relative humidity (r=-0.6, Slope=-4.52, and SD=±2.68) plays a moderate linear relationship in influencing the incidences of forest fires. However, wind velocity showed almost a flat curve indicating its minimal role in influencing forest fire incidences. Parameter modelling and preparation of forest fire risk zone map would be an effective tool in preventing and managing forest fire in Sikkim.
森林生态系统正在枯竭并走向退化,这将对世界的社会经济和谐产生不利影响。各种灾害扰乱了动植物的亲密关系,造成了生态的整体失衡;森林火灾就是其中之一。2015年至2017年间,印度的森林火灾发生率上升了125%。本文对锡金地区森林火灾的各种影响因素进行了研究和分析。研究考虑了10年的森林火灾事件,即从2004年到2014年。森林火灾数据从锡金政府森林和环境部收集,并进行初步处理以检查异常。该研究发现,近年来森林火灾的发生率一直在增加,其中2009年的发生率最高。这些火灾共破坏了5,047.16公顷的土地,破坏了各种动植物。研究发现,森林火灾多发地区主要集中在海拔1500m以下、冬季(12月至2月至3月)和亚热带赤杨(Shorea robusta)林。锡金西部地区的森林火灾发生率和覆盖面积最高,其次是南部和东部地区;北部地区受影响最小。通过对森林火灾发生数据的可视化解读和文献综述,锡金地区森林火灾的主要影响因素是降雨量少、冬季干燥和植被类型。此外,在2009-2014年期间(n=389),平均温度(°C)、相对湿度(%)和风速(Km/h)等天气因素对森林火灾发生率进行了线性回归。结果表明,平均温度(r=0.37, Slope=9.59, SD=±12.00)和相对湿度(r=-0.6, Slope=-4.52, SD=±2.68)对林火发生的影响呈中等线性关系。风速几乎呈平坦曲线,表明风速对森林火灾的影响最小。参数建模和编制森林火灾危险区图将是锡金预防和管理森林火灾的有效工具。

Seasonal dynamics in tropical forests are closely related to the variation in forest canopy gaps. The canopy gaps change continuously in shape and size between the rainy and dry seasons, leading to the variation in the vegetative indicators. To monitor the variation of the canopy gaps, UAVs were used to collect datas in the mentioned tropical forests at an altitude of over 1,000m in Ngoc Linh Nature Reserve, Vietnam with a post-processing image resolution of about 8cm, which allows the detection of relatively small gaps. The analysis results at 10 squares of 1 ha showed a decrease in the area of ​​ canopy gaps from the rainy season in September 2019 to the dry season of May 2020. The mixed broad-leaved or broadleaf forest dominates with a greater variation, when the area of ​​the gaps decreases significantly. The variation in forest canopy gaps and vegetative indicators are closely related to the high differentiation of terrain, the seasonal and the dry season climatic characteristics. The fluctuation of the vegetation cover affects the habitats of the species under the forest canopy such as animals, birds and soil fauna. This is one of the scientific bases that contributes to the management and conservation of flora and fauna biodiversity, especially in mountainous tropical forests such as Ngoc Linh Nature Reserve.
热带森林的季节动态与林冠间隙的变化密切相关。在雨季和旱季之间,林隙的形状和大小不断变化,导致植被指标的变化。为了监测冠层间隙的变化,我们使用无人机在越南Ngoc Linh自然保护区海拔1000米以上的热带森林中收集数据,其后处理图像分辨率约为8cm,可以检测到相对较小的间隙。10平方/ 1 ha的分析结果显示,从2019年9月的雨季到2020年5月的旱季,冠层间隙面积减少。阔叶林和混交林占主导地位,变化较大,林隙面积明显减小。林冠间隙和植被指标的变化与地形的高度分异、季节和旱季气候特征密切相关。植被覆盖度的波动影响着林冠下动物、鸟类和土壤动物等物种的栖息地。这是有助于管理和保护动植物生物多样性的科学基础之一,特别是在山区热带森林,如玉林自然保护区。

Globally, various sectors were adversely affected by the emergence of the COVID-19 pandemic. Therefore, this study aims to determine the economic condition of bamboo craftsmen in Mandalagiri Village, Leuwisari District, Tasikmalaya Regency, West Java Province, Indonesia. This is an in-depth research with data obtained by interviewing 35 bamboo craftsmen with various products and production scales. The results showed that craftsmen were not economically affected by the pandemic rather by the central government-stipulated regulation on social distancing, which led to their inability to transport their product from Tasikmalaya to Jakarta and other regions. However, since the government lifted the ban, their income has increased by an average of 2%. The result further showed that the main factor that keeps craftsmen from being negatively affected by the pandemic is the increasing online market demand supported by the availability of raw materials and the ability to adapt to various new model products. Other factors linked to the national market and products answer the demand of the modern market in the cities. Meanwhile, the main factors that positively affect the craftsmen's income are age and marital status.
在全球范围内,各部门都受到2019冠状病毒病大流行的不利影响。因此,本研究旨在确定印尼西爪哇省Tasikmalaya Regency, Leuwisari区Mandalagiri村竹工匠的经济状况。本研究通过对35名不同产品和生产规模的竹工匠进行访谈,获得数据。结果表明,手工艺人没有受到疫情的经济影响,而是受到中央政府规定的社会距离规定的影响,这导致他们无法将产品从塔斯克马来亚运送到雅加达和其他地区。然而,自从政府解除禁令以来,他们的收入平均增长了2%。结果进一步表明,使工匠免受疫情负面影响的主要因素是,在原材料可用性和适应各种新型号产品能力的支持下,在线市场需求不断增加。与全国市场和产品相关的其他因素满足了城市现代市场的需求。同时,对工匠收入产生正向影响的主要因素是年龄和婚姻状况。

Mangroves provide benefits and various services to local communities living along coastal areas, particularly fishery communities. Fishery community perceptions are significant in determining attitudes towards improving mangrove conditions, which can also be addressed through restoration activities. This research was conducted to analyze fisheries communities perceptions, willingness to pay (WTP) for mangroves restoration, and mangrove forest management strategies. Field surveys were conducted from July-August 2019 and February-March 2020. Primary data were collected from respondents in four regions (Kalianda Regency, South Lampung Regency, Bandar Lampung City, and Pesawaran Regency) in Lampung Province, Indonesia, which consist of fishers, shrimp farmers, crab and wood seekers, and finfish farmers. The respondents were 193 people, and four experts were involved in the policy scenario analysis. Results revealed a gap in the value of WTP among fishery community groups, in which the average value for fishers is lower than shrimp farmers. The years of formal education significantly influenced the WTP for mangrove restoration. Based on the scenario analysis, scenario 01 become a priority strategy, where four policies (P1 = Mangrove ecotourism development in Lampung Bay; P2 = Mangrove knowledge education and training on processing mangrove based products; P3 = Restoration and conservation of mangrove forests; and P4 = Community-based management for mangrove forests utilization) show high likelihoods to be simultaneously implemented for mangroves management, with mangrove ecotourism policy as the most decisive policy. For future research, other explanatory variables can be added, such as information on family member characteristics, and to develop a bottom-up policy scenario by identifying and involving the role of the local community.
红树林为生活在沿海地区的当地社区,特别是渔业社区提供了利益和各种服务。渔业社区的看法在决定对改善红树林状况的态度方面具有重要意义,这也可以通过恢复活动加以解决。本研究旨在分析渔业社区对红树林恢复的认知、支付意愿(WTP)以及红树林管理策略。实地调查于2019年7月至8月和2020年2月至3月进行。主要数据是从印度尼西亚楠榜省四个地区(Kalianda县、南楠榜县、Bandar楠榜市和Pesawaran县)的受访者中收集的,这些地区包括渔民、虾农、捕蟹者和采木者以及鳍鱼养殖者。调查对象共有193人,4名专家参与了政策情景分析。结果显示,渔业社区群体之间的WTP值存在差距,其中渔民的平均值低于虾农。正规教育年限对红树林恢复WTP有显著影响。基于情景分析,情景01成为优先战略,其中四项政策(P1 =楠榜湾红树林生态旅游开发;P2 =红树林知识教育和红树林产品加工培训;P3 =恢复和保护红树林;和P4 =以社区为基础的红树林利用管理)显示红树林管理同时实施的可能性很高,其中红树林生态旅游政策是最具决定性的政策。在未来的研究中,可以增加其他解释变量,如家庭成员特征的信息,并通过确定和参与当地社区的作用来制定自下而上的政策情景。

The purpose of this study was to investigate how the COVID-19 pandemic affects the organic rice production system in four districts of Chiang Mai Province. Eight organic farmers were purposefully chosen as informants because they have possessed forty-seven resilience components (SERCs) needed to cope with all kinds of social-ecological change. They were asked using a structured questionnaire to assign each SERC’s contribution value before and after the COVID-19 pandemic, in which each time scoring must be coupled with entailed explanations. Then, the paired samples t-test was run to compare such means of SERCs’ contribution values to examine whether their organic rice production’s resilience was affected by the pandemic and how. Results showed the means of SERCs before and after the pandemic have no significant difference as the p-value is 1.00 at the 95% confidence interval. This meant the pandemic does not influence the organic rice production’s social-ecological resilience. But several practices and qualifications were found varying from the original to make production more suitable. The dependence on household labor and that on mutual labor exchange were respectively increased and decreased in their roles in resilience building. Labor availability was interrupted by the social distancing protocol that had restricted people from gathering. Besides, the household accounts recording was adopted more than usual for being seen as a solution to improving the household economy during the time of financial vulnerability. Importantly, relying on local goods was remarkably recognized for increased importance. This was an attempt to get access to materials possibly free from the COVID-19 contamination because of the absent transportation. These findings provide two key interests. They can be applied as a framework not only to strengthen agricultural resilience but also to propose a blueprint of coping mechanisms against the pandemic at a mass scale.
本研究的目的是调查COVID-19大流行如何影响清迈省四个地区的有机水稻生产系统。有针对性地选择了8名有机农民作为调查对象,因为他们拥有47种应对各种社会生态变化所需的弹性成分(SERCs)。他们被要求使用结构化问卷来分配每个SERC在COVID-19大流行之前和之后的贡献值,其中每次评分都必须加上所需的解释。然后,进行配对样本t检验,比较这些SERCs的贡献值,以检验其有机水稻生产的恢复能力是否受到大流行的影响以及如何受到影响。结果显示,大流行前后SERCs均值无显著差异,95%置信区间p值为1.00。这意味着疫情不会影响有机水稻生产的社会生态复原力。但一些做法和资格被发现与原来不同,以使生产更适合。对家庭劳动的依赖和对相互劳动交换的依赖在弹性建设中的作用分别增强和减弱。限制人们聚集的社交距离协议中断了劳动力供应。此外,在财政脆弱时期,家庭帐户记录被视为改善家庭经济的一种解决办法,因此比以往更多地被采用。重要的是,依靠当地商品的重要性显著提高。这是为了获得可能没有COVID-19污染的材料,因为没有运输。这些发现提供了两个关键的兴趣。它们不仅可以作为加强农业抗灾能力的框架加以应用,而且还可以提出大规模应对这一流行病的机制蓝图。

Forest land allocation and use in Indonesia have been politically contested and characterized by poor data and competing interests of different institutions. This study analyzes the process of integrating scientific findings in policymaking about land use and changes. The focus is on the processes related to the changes of Highly Important Forest Zones with Strategic Values (Dampak Penting Cakupan Luas dan bernilai Strategis/DPCLS). DPCLS forests are unique as any changes require approval from the parliament to complement the processes at the Ministry of Environment and Forestry and must be based on rigorous scientific evaluation. This study uses the case of Riau Islands (Kepri) Province, previously part of Riau Province, which to date is one of only two Indonesian provinces yet to accept the forest zonings of the Ministry. The province’s strategic positions as exclusive economic and free trade zones make it further interesting in terms of land allocation as land becomes increasingly valuable for other uses. This paper specifically asks how the scientific investigation on the potential land use changes were conducted, how reliable the discoveries are, and how they were utilized in multiple steps at different institutions from the proposal evaluations to the approval stages. Our research indicates that scientific findings have rarely been integrated in policy making regarding DPCLS forests in Kepri Province. In addition, the scientific findings are weak; the institution producing them is heavily dominated by government officials and paid consultants/ experts. The scientific body was only established to fulfill the formal processes required by the regulatory frameworks. Proposals and decisions on the changes of DPCLS forests in Kepri Province are more characterized by political considerations. The “scientific findings” of the current land use in Kepri Province is used as a political commodity (or commodities) to support the interests of actors.
印度尼西亚的森林土地分配和使用在政治上存在争议,其特点是数据不足,不同机构的利益相互竞争。本研究分析了将科学发现整合到土地利用与变化政策制定的过程。重点是与具有战略价值的高度重要林区(Dampak Penting Cakupan Luas dan bernilai Strategis/DPCLS)变化有关的过程。DPCLS森林是独一无二的,因为任何改变都需要得到议会的批准,以补充环境和林业部的流程,并且必须基于严格的科学评估。本研究以廖内群岛(Kepri)省为例,该省以前是廖内省的一部分,迄今为止是印度尼西亚仅有的两个尚未接受该部森林区划的省份之一。该省作为专属经济区和自由贸易区的战略地位,使其在土地分配方面变得更加有趣,因为土地在其他用途上变得越来越有价值。本文具体探讨了土地利用潜在变化的科学调查是如何进行的,这些发现的可靠性如何,以及如何在不同机构从提案评估到批准阶段的多个步骤中加以利用。我们的研究表明,科学发现很少被纳入Kepri省DPCLS森林的政策制定中。此外,科学发现也很薄弱;制作它们的机构在很大程度上由政府官员和付费顾问/专家主导。科学机构的建立只是为了履行监管框架所要求的正式程序。关于Kepri省DPCLS森林变化的建议和决定更多地具有政治考虑的特点。Kepri省当前土地利用的“科学发现”被用作支持行为者利益的政治商品(或商品)。

Soil seed banks have been used for investigation of natural regeneration of forests. In this study, we compared seed density and species composition of soil seed banks of trees among natural forests, restored forests of different ages, and abandoned agricultural land. The soil seed banks were collected from a natural forest (NF), 12-year-old and 17-year-old restoration sites (RF12y and RF17y), and 17-year-old abandoned site (AA) at Ban Mae Sa Mai, Chiang Mai, Thailand. A seedling emergence technique was used to assess seed density and species of emerged seedlings was identified. We found 5-8 tree species at each site. Seed densities in the study areas ranged from 43 to 298 seeds/m2. The seed density of RF12y was significantly higher than that of both NF and AA but not significantly different than RF17y (p < 0.01). Although there was no significant relationship between the restoration ages and the seed densities of the soil seed banks, the species composition of standing vegetation was related to the seed bank species. Sorensen’s similarities between the species composition of the soil seed banks and the existing trees in each area were between 0 and 13.79%, suggesting seed dispersal of both within and across study sites. Eight out of fourteen species in the soil seed banks were dispersed into restoration sites without standing vegetation of those species. Seven of those were animal-dispersed species. The selected native trees, framework species, attracted small seed dispersers into the study areas, especially at the restoration sites. This finding suggests that active forest restoration improved natural regeneration in restoration sites as well as neighboring areas via seed dispersal.
土壤种子库已被用于森林自然更新的调查。本研究比较了天然林、不同龄期恢复林和撂荒农用地土壤树种种子库的种子密度和物种组成。土壤种子库收集自泰国清迈Ban Mae Sa Mai的天然林(NF)、12年和17年的恢复点(RF12y和RF17y)和17年的废弃点(AA)。采用出苗技术评价种子密度,鉴定出出苗种类。我们在每个地点发现了5-8种树种。研究区种子密度为43 ~ 298粒/m2。RF12y的种子密度极显著高于NF和AA,但与RF17y差异不显著(p < 0.01)。虽然恢复年龄与种子库种子密度关系不显著,但立地植被的物种组成与种子库物种有关。土壤种子库的物种组成与各地区现有树木的Sorensen相似度在0 ~ 13.79%之间,表明种子在研究点内和研究点间都有传播。土壤种子库中14种植物中有8种被分散到没有植被的恢复地点。其中7种是动物分散物种。所选择的本地树种,框架树种,吸引了小型种子传播者进入研究区域,特别是在恢复地点。这一发现表明,积极的森林恢复通过种子传播促进了恢复地点及其周边地区的自然更新。
