ABSTRACT Agarwood (Aquilaria malaccensis Lam.) (Thymelaeaceae) is valued in many cultures because of its distinctive fragrance and its use in incense, perfumery, and traditional medicine. Large-scale harvesting from natural populations caused rapid depletion of the species in the wild, and the species is now listed as “Critically Endangered” and almost extinct in the wild. The promotion of this species in agroforestry systems may pave the way for its conservation. The present study aimed to quantify the growth and coppicing ability of agarwood under monoculture and polyculture stands. Monoculture stands aged more than 20 years, and stem girth (1.37 m above ground) of 60–70 cm had the highest growth increment of 3.73 cm yr−1. Monoculture stands (>10 years old) also recorded higher number of coppicing stocks than polyculture stands. The highest coppice growth increment (4.07 cm yr−1) was recorded in the 70–80 cm stem girth in monoculture stands. Based on the results, we recommend the promotion of agarwood trees with good coppice management in forestry programs to conserve the species while also meeting the economic needs of rural communities.
琼脂(Aquilaria malacensis Lam.)(百里香科)因其独特的香味以及在香、香水和传统医学中的应用而在许多文化中受到重视。从自然种群中大规模采集导致该物种在野外迅速枯竭,该物种现在被列为“极度濒危”物种,在野外几乎灭绝。在农林系统中推广该物种可能为其保护铺平道路。本研究旨在量化单一栽培和混合栽培林分下沉香木的生长和coppicing能力。年龄超过20年、茎围(离地1.37米)为60–70厘米的单一栽培林分的生长增量最高,为3.73厘米yr−1。单一栽培林分(>10年树龄)也记录了比混合栽培林分更高的群落种群数量。在单作林分中,70–80 cm的茎围记录到最高的矮林生长增量(4.07 cm yr−1)。根据研究结果,我们建议在林业项目中推广具有良好矮林管理的沉香树,以保护该物种,同时满足农村社区的经济需求。

ABSTRACT The increasing concern for sustainable forest and protected forest resources motivates this study. In the wake of rising protected forest depletion, climate change and public health problems, this study through a bidding game format develops a sustainability index to show households’ sustainability behavior toward the protected forests in the Greater Accra Region of Ghana. Relying on a cross-section of household survey data and regression analysis, this study finds that overall, approximately 79% of respondents exhibited sustainable behavior toward protected forests in GAR. Also, this sustainable behavior is associated with expected revenue of GH¢ 80,837,594 (USD$ 15,368,398) per annum. We also find that socioeconomic, psychological, and environmental factors are the main drivers of protected forest sustainability in the Greater Accra Region, Ghana. This study has important implications for institutions working toward sustaining protected forest and forest resources in Ghana.
摘要:随着人们对森林可持续发展和森林资源保护的日益关注,本研究应运而生。在受保护森林枯竭、气候变化和公共卫生问题日益严重的背景下,本研究通过竞标游戏的形式开发了一个可持续性指数,以显示加纳大阿克拉地区家庭对受保护森林的可持续性行为。根据家庭调查数据的横截面和回归分析,本研究发现,总体而言,约79%的受访者对GAR中的受保护森林表现出可持续的行为。此外,这种可持续的行为与每年80,837,594新台币(15,368,398美元)的预期收入有关。我们还发现,社会经济、心理和环境因素是加纳大阿克拉地区受保护森林可持续性的主要驱动因素。这项研究对加纳致力于维持受保护森林和森林资源的机构具有重要意义。

ABSTRACT The Corchal “El Mono Hernández” Fauna and Flora Sanctuary is a protected area located in northern Colombia and is home to the Pterocarpus officinalis forest. In this area, however, this forest cover is declining due to natural causes associated with a change in the hydrosedimentological dynamics. Multitemporal assessment was performed to quantify the forest loss. Landsat images from the years 1986, 1998, 2003, 2013, and 2018 were downloaded and a supervised classification was performed using four cover classes: “Pterocarpus officinalis,” “other vegetation,” “waterbody,” and “bare land.” The results showed that the vegetation cover of Pterocarpus officinalis forest had an initial extent of 865.26 ha in 1986; for the 1986–1998 period, the reduction was 60.30 ha; for the 1998–2003 period, it was 399.15 ha; and for the 2003–2013 period, it was 78.30 ha. Contrary to previous periods, in the 2013–2018 period, 79.65 ha of forest was recovered. In conclusion, Pterocarpus officinalis forest lost approximately 50% of its cover during the 1986–2018 period. This information is of great importance for government and management entities for decision-making in the conservation and restoration of this forest.
摘要Corchal“El Mono Hernández”动植物保护区位于哥伦比亚北部,是Pterocarpus officinalis森林的所在地。然而,在该地区,由于与水文地质动力学变化相关的自然原因,森林覆盖率正在下降。进行了多时间评估,以量化森林损失。下载1986年、1998年、2003年、2013年和2018年的陆地卫星图像,并使用四个覆盖类别进行监督分类:“Pterocarpus officinalis”、“其他植被”、“水体”和“裸地”;1986年至1998年期间,减少面积为60.30公顷;1998年至2003年期间为399.15公顷;2003-2013年期间为78.30公顷。与之前的时期相反,在2013-2018年期间,恢复了79.65公顷的森林。总之,在1986年至2018年期间,Pterocarpus officinalis森林失去了约50%的覆盖率。这些信息对政府和管理实体在保护和恢复森林方面的决策具有重要意义。

ABSTRACT Wild edible fruit plant species (WEFs) are species that are not cultivated or domesticated but are available in their natural habitat, providing a readily available source of food, medicine, and economic value to the local people. In recent times, WEFs have been threatened by over-exploitation, land-use changes, and biodiversity loss. This study aims to (1) identify and document wild edible fruit plant species, (2) investigate the patterns of knowledge, use, and management of WEFs in the Ulu Masen protected area; and (3) assess threats to wild edible fruit plant species and recommend possible management scenarios for their conservation. The study was conducted in six villages of Pantai Ceuremen subdistrict, Southeast Aceh, Indonesia, namely Sikundo, Jambak, Canggai, Lawet, Pulo Tungoh, and Keutambang. The plant materials were randomly collected from the study area, while local knowledge was gathered through a semi-structured survey and in-depth interviews involving 209 respondents that were selected using random sampling. A total of 53 wild edible fruit plants from 30 genera and 21 families were found to be commonly used. Syzygium pycnanthum, Syzygium littorale, Syzygium polyanthum, Garcinia xanthochymus, Baccaurea polyneura, Flacourtia rukam, Sandoricum koetjape, and Baccaurea racemosa were the most important species for local communities in the study area. The WEFs in the study area is influenced by a variety of factors, primarily agricultural expansion, which means that conservation practices need to be improved through the implementation of management strategies, prioritizing species currently used by local communities. Management strategies based on traditional knowledge, such as community-based forest management systems (CBFMS) are being considered for future conservation, and they are also being implemented in other developing countries with similar circumstances.
摘要:野生食用果树(WEF)是指未经栽培或驯化,但在其自然栖息地可以获得的物种,为当地人民提供了现成的食物、药品和经济价值来源。近年来,世界经济论坛受到过度开发、土地利用变化和生物多样性丧失的威胁。本研究旨在(1)识别和记录野生食用果树物种,(2)调查乌鲁马森保护区WEF的知识、使用和管理模式;以及(3)评估对野生可食用果树物种的威胁,并为其保护提出可能的管理方案。该研究在印度尼西亚亚齐东南部Pantai Ceuremen街道的六个村庄进行,即Sikundo、Jambak、Cangai、Lawet、Pulo Tungoh和Keutambang。植物材料是从研究区域随机收集的,而当地知识是通过半结构化调查和深入访谈收集的,涉及209名受访者,他们是通过随机抽样选出的。共发现21科30属53种野生食用果树为常用果树。pycnanthum、Syzygium littoralle、Syzygium polyanthum,黄壶藤、多菌Baccaurea polyneura、黄曲霉Flacoutina rukam、Sandoricum koetjape和总状杆菌是研究区当地群落最重要的物种。研究区域的WEF受到多种因素的影响,主要是农业扩张,这意味着需要通过实施管理战略来改善保护做法,优先考虑当地社区目前使用的物种。基于传统知识的管理战略,如基于社区的森林管理系统,正在考虑用于未来的养护,其他情况类似的发展中国家也在实施这些战略。

ABSTRACT Adoption of agroforestry, which is a combination of growing perennial trees along with crops and/or livestock in spatial and temporal arrangements, is recommended for improving the livelihoods of smallholders. Alike several other technologies, the adoption status of agroforestry innovations in sub-Saharan Africa is considered poor. Studies have shown that plethora of biophysical and socioeconomic variables affect adoption of agroforestry innovations. In these studies, the contribution of psychological variables determining the voluntary decision-making on agroforestry adoption decisions is often neglected and marginally explored. This paper aims at exploring the role of psychological variables for the sustained agroforestry adoption intention. We employed the Theory of Planned Behavior (TPB) to predict sustained agroforestry adoption intentions of 327 farmers in the Amhara region of Ethiopia. Intention for sustained agroforestry woodlots adoption is assessed by employing the confirmatory factor analysis. Farmers’ intention to sustain adoption of agroforestry woodlot innovations is principally driven by their positive evaluation of the cash and livelihood benefits of the innovations (attitude) compared to traditional farming, their own capability to produce the innovations and accessibility of resources (perceived behavioral control), and the farmers’ perception of pressure and expectations from experts and important others (subjective norms). By employing TPB, this study brings a theoretical contribution to the TPB framework and measurement guidelines, unveils limitations of applying confirmatory factor analysis in a ‘new’ (woodlots) context and suggests data-based policy and development implications.
建议采用农林业,即在空间和时间安排上将多年生树木与作物和/或牲畜相结合,以改善小农的生计。与其他几种技术一样,农林业创新在撒哈拉以南非洲的采用状况被认为很差。研究表明,过多的生物物理和社会经济变量影响农林业创新的采用。在这些研究中,决定农林业采用决策的自愿决策的心理变量的贡献往往被忽视和很少探索。本文旨在探讨心理变量对持续农林业采用意愿的作用。本文运用计划行为理论(TPB)对埃塞俄比亚阿姆哈拉地区327名农民的持续农林业采用意向进行了预测。采用验证性因子分析评估持续农林业林地采用的意向。农民持续采用农林业林地创新的意愿主要受到以下因素的驱动:与传统农业相比,他们对创新的现金和生计效益(态度)的积极评价,他们自己生产创新的能力和资源的可及性(感知行为控制),以及农民对专家和重要其他人的压力和期望的感知(主观规范)。通过采用TPB,本研究为TPB框架和测量指南带来了理论贡献,揭示了在“新”(林地)环境中应用验证性因子分析的局限性,并提出了基于数据的政策和发展建议。

ABSTRACT Farmers are adopting different agroforestry practices, but comparative studies between the practices based on ecosystem functions are often ignored. We assessed species composition and carbon stock in two different agroforestry practices (traditional and improved) adopted in the mid-hills of Nepal. We found higher species richness and dominancy of Citrus synenssis (fruit species) in the improved practice, whereas we found higher species evenness, diversity, and dominance of Ficus clavata (fodder species) in the traditional practice. 0.35 of the similarity index between the two practices indicated that there was 65% difference in species number between the two practices. The improved practice had larger trees with higher frequency compared to traditional practice. The carbon inventory reflected that the total carbon stock between the two practices was insignificant, whereas the total biomass carbon was significantly higher in the improved practice than in the traditional practice. Therefore, improvement in traditional practices has the potential to increase biomass and sequester more carbon within the same unit of land. However, maintaining species diversity is a concern in the improved practice. We suggest policymakers and concerned stakeholders for prioritizing improved agroforestry practice and maintain species diversity while designing strategies for agroforestry promotion and climate change mitigation.
农民正在采用不同的农林业实践,但基于生态系统功能的实践之间的比较研究往往被忽视。我们评估了尼泊尔中部山区采用的两种不同农林业实践(传统和改进)的物种组成和碳储量。结果表明,改良栽培方式中柑橘属(Citrus synensis)的物种丰富度和优势度较高,而传统栽培方式中无花果属(Ficus clavata)的物种均匀度、多样性和优势度较高。相似指数为0.35,表明两种做法之间的物种数量差异为65%。与传统做法相比,改进的做法有更大的树木和更高的频率。碳储量反映了两种做法之间的总碳储量差异不显著,而改进做法的总生物量碳显著高于传统做法。因此,改进传统做法有可能增加生物量,并在同一单位土地内吸收更多的碳。然而,在改进的做法中,保持物种多样性是一个值得关注的问题。我们建议决策者和相关利益相关者在制定促进农林业和减缓气候变化战略的同时,优先考虑改进农林业实践并保持物种多样性。

ABSTRACT Projected climate change presents many challenges and opportunities for individuals, households and wider society on how to adapt. Local knowledge is key to help smallholder farmers to cope with climate change and variability to attain sustainable forest management. However, there is limited understanding of what shapes human adaptation to climate change in various sectors at local level including forestry in sub-Saharan Africa. Therefore, this study explored the awareness, knowledge and perception of forest-dependent communities on climate change and variability around Phirilongwe and Mchinji forest reserves in Malawi. Empirical data was collected using household surveys (n = 422), key informant interviews (16), and focus group discussions (8). Results suggest that 60% of respondents in Mchinji were aware of climate change as compared to only 35% in Mangochi. Results record that respondents perceived increased erratic rainfall, high temperatures and strong winds and changes in seasons. The main factors influencing their climate perception includes possession of farming skills (p = .002), Education (P = .04), gender (P = .002) and possession of livestock keeping skills (p = .02). However, the cube root stratification method indicates that their level of knowledge falls in the low-level category. Although negligible proportion of climate skepticisms was exposed, a strong belief in anthropogenic causes of climate change and willingness to adopt environmental friendly intervention measures were revealed. However, the presence of the believers in the cultural and spiritual causes of climate change in the study area presents a challenge to mobilize them toward implementation of climate intervention measures and forest management. We therefore recommend their participation in the climate adaptation intervention designs and multiple use of various strategies and methods that will help to address their livelihoods at the same time improve their climate information and knowledge.
预估的气候变化给个人、家庭和更广泛的社会带来了许多如何适应的挑战和机遇。当地知识是帮助小农应对气候变化和变异、实现可持续森林管理的关键。然而,对于是什么影响了包括撒哈拉以南非洲林业在内的各个地方部门的人类对气候变化的适应,人们的了解有限。因此,本研究探讨了马拉维Phirilongwe和Mchinji森林保护区周围森林依赖社区对气候变化和变率的认识、知识和感知。通过家庭调查(n = 422)、关键信息者访谈(16)和焦点小组讨论(8)收集经验数据。结果表明,Mchinji 60%的受访者意识到气候变化,而Mangochi只有35%。调查结果显示,受访者认为不稳定的降雨、高温、强风和季节变化增加了。影响其气候感知的主要因素包括是否拥有农业技能(p = .002)、教育程度(p = .04)、性别(p = .002)和是否拥有牲畜饲养技能(p = .02)。然而,立方根分层法表明,他们的知识水平属于低水平范畴。尽管气候怀疑论者的比例可以忽略不计,但人们强烈相信气候变化的人为原因,并愿意采取环境友好的干预措施。然而,研究区域气候变化的文化和精神原因的信徒的存在对动员他们实施气候干预措施和森林管理提出了挑战。因此,我们建议他们参与气候适应干预设计,并多种使用各种战略和方法,这些战略和方法将有助于解决他们的生计问题,同时改善他们的气候信息和知识。

ABSTRACT Recall of natural environments evokes human psychophysiological response, there is a lack of systematic, comprehensive analysis in existing research. Moreover, the limited experimental conditions lead to various laboratory research, and more field studies are needed. Employing the field research design and relative environmental psychology methods, this research investigates physical and psychological indexes changes of 60 Chinese university students aged 19–25, which include positive affect (PA), negative affect (NA), heart rate (HR), heart-rate variability (HRV), concentration (Pa), and relaxation (Pm), and regards the Zhangjiajie National Forest Park in China as the experimental site. This study evaluates the psychophysiological effects of the natural forest environment on participates and explores the overall psychophysiological changes, and verifies the positive effect of the natural forest environment on university students. The main findings indicated that the natural forest environment was beneficial for increasing positive affect, decreasing negative affect, affecting HR, and increasing HRV, Pa and Pm. This study adds some basic evidence to a growing theoretical literature emphasizing the role of natural forest environment in psychophysiological restoration.

Forest ecological benefit compensation plays a promoting role in improving the enthusiasm of forest ecological builders and maintainers, maintaining the legitimate economic interests of forest owners, and coordinating the fairness between the “clear water and green mountains” protectors and the “gold and silver mountains” beneficiaries. Comprehensive combed the domestic forest ecological benefit compensation mechanism, including the compensation scope, compensation subject, compensation object, the research progress of compensation standard, summarized the forest ecosystem benefits measurement, including physical appraisal method, the value evaluation method, energy analysis method and the characteristics and application research progress of ecological model method. This paper discusses the research status and existing problems of the calculation basis of compensation standard, the origin, research emphasis and progress of forest ecological service payment abroad in recent years, and the mechanism of forest ecological service payment in many countries. Finally, some suggestions are put forward to improve the compensation mechanism of forest ecological benefits in China. On the one hand, it is necessary to broaden the source of funds through various ways of marketization and scientifically evaluate the forest ecological benefits. On the other hand, the compensation standard should be established scientifically and reasonably to achieve different compensation levels or compensation intervals.
森林生态效益补偿在提高森林生态建设者和维护者的积极性、维护林主的合法经济利益、协调“绿水青山”保护者和“金山银山”受益者之间的公平等方面具有促进作用。全面梳理了国内森林生态效益补偿机制,包括补偿范围、补偿主体、补偿对象、补偿标准的研究进展,总结了森林生态效益测量方法,包括物理评价法、价值评价法、能量分析法和生态模型法的特点及应用研究进展。论述了补偿标准的计算依据、近年来国外森林生态服务支付的起源、研究重点和进展、各国森林生态服务支付机制等方面的研究现状和存在的问题。最后,提出了完善中国森林生态效益补偿机制的建议。一方面,要通过多种市场化途径拓宽资金来源,科学评价森林生态效益;另一方面,要科学合理地制定薪酬标准,实现不同的薪酬水平或薪酬间隔。

Based on the collective forest with common use rights, the social-ecological system analysis framework and autonomous governance theory proposed by Elinor Ostrom are introduced in the forest eco-economic system to analyze the interaction logic among the first-level subsystems and the secondary variables of the forest eco-economic system and the variables related to the autonomous governance of the system to explore the synergistic mechanisms affecting the forest eco-economic system. The results show that: in the case of information asymmetry, collective actions of governmental and non-governmental organizations will aggravate the dilemma of forest eco-economic synergistic development; actors extract forest resource units from the forest resource system to achieve economic benefits; and renewable resources of forest ecosystems can be sustained in the long term when the average extraction rate of humans from forest ecosystems does not exceed the average replenishment rate.
以集体共有使用权森林为基础,在森林生态经济系统中引入埃莉诺·奥斯特罗姆(Elinor Ostrom)提出的社会生态系统分析框架和自治治理理论,分析森林生态经济系统的一级子系统和二级变量与系统自治治理相关变量之间的交互逻辑,探索影响森林生态经济系统的协同机制。结果表明:在信息不对称的情况下,政府和非政府组织的集体行动将加剧森林生态经济协同发展的困境;行动者从森林资源系统中提取森林资源单位,实现经济效益;当人类对森林生态系统的平均采取率不超过平均补充率时,森林生态系统的可再生资源可以长期持续。
