ABSTRACTAcacia decurrens (hereafter Acacia) agroforestry system has been expanding rapidly in the northwestern highlands of Ethiopia. The agroforestry system provides multiple eco-environmental services; however, there is inadequate quantitative evidence on its livelihood benefits. This study, therefore, investigated the livelihood benefits and challenges of Acacia-based agroforestry system in the Awi area, Northwest Ethiopia. Data was collected through household survey quetionnaires (296 randomly selected Acacia growers), focused-group discussions, interviews, and observations. A combination of quantitative and qualitative methods was used for the data analysis. The findings showed that crop production, charcoal making, animal rearing, and fuelwood selling were the major sources of livelihood. Notwithstanding the complex challenges (Acacia pests/diseases, traditional charcoal-making, limited road access and market opportunities, negative human-health impacts, and high production cost), Acacia-based agroforestry positively affected farmers livelihoods. Comparatively, the natural, physical, financial, human and social capital indices of farmers were higher by 0.25, 0.24, 0.43, 0.25, and 0.06, respectively, in the post-than pre-Acacia periods. The overall livelihood index of farmers increased from 0.47 (pre-Acacia) to 0.71 in the post-Acacia period. The study concluded that this agroforestry practice has immense livelihood benefits, although diverse challenges question its sustainability. Therefore, short and long-term strategies should be designed to strengthen the opportunities and address the challenges.KEYWORDS: Acacia-basedagroforestrychallengeslivelihood assetslivelihood benefitsnorthwest Ethiopia AcknowledgementsWe acknowledge Bahir Dar University and Injibara University for their financial support to the first author.

槐(Acacia decurrens,简称Acacia)农林复合系统在埃塞俄比亚西北部高地迅速扩展。农林复合系统提供多种生态环境服务;然而,关于其生计效益的量化证据不足。因此,本研究调查了埃塞俄比亚西北部Awi地区以金合欢为基础的农林业系统的生计效益和挑战。通过家庭调查问卷(随机选择296名金合欢种植者)、焦点小组讨论、访谈和观察收集数据。采用定量与定性相结合的方法对数据进行分析。调查结果表明,农作物生产、木炭制造、动物饲养和薪柴销售是主要的生计来源。尽管面临着复杂的挑战(金合欢病虫害、传统的制炭、有限的道路通道和市场机会、对人类健康的负面影响以及生产成本高),但金合欢农林业对农民的生计产生了积极影响。相比之下,农民的自然资本、物质资本、金融资本、人力资本和社会资本指数在金合欢发生后比发生前分别提高了0.25、0.24、0.43、0.25和0.06。农民的整体生计指数从0.47(相思前)上升到0.71(相思后)。该研究的结论是,这种农林业实践具有巨大的生计效益,尽管各种挑战质疑其可持续性。因此,应制定短期和长期战略,以加强机遇和应对挑战。关键词:金合欢农林业挑战生计资产生计效益埃塞俄比亚西北部致谢我们感谢Bahir Dar大学和Injibara大学对第一作者的经济支持。作者还感谢研究地区的金合欢种植户、发展机构和政府官员在实地工作期间的合作和提供的数据。披露声明作者未报告潜在的利益冲突。补充材料本文的补充数据可在https://doi.org/10.1080/14728028.2023.2268646.Notes1上在线获取。埃塞俄比亚最小的行政单位金合欢树的当地名称。一个以社区为基础的机构,在困难时期帮助成员。这项工作得到了Bahir Dar大学的支持。

ABSTRACT Voluntary incentive programs exist to encourage the conservation and sustainable management of privately owned forests. This study of Georgia family forest landowners used a gender-focussed approach to examine: the extent to which learning sources predict landowners’ familiarity with forest conservation programs; the association between familiarity with and participation in conservation programs; and landowners’ familiarity with forest-based ecosystem services (ESs). We analysed data (N = 223) from a mail survey using Ordinary Least Squares models to predict landowners’ familiarity with conservation programs, tested the association between familiarity with and participation in conservation programs, and evaluated landowners’ familiarity with ESs using qualitative content analysis. Professional forest-management advice and training were associated with familiarity with conservation programs, but gender (being female) was a negative predictor. There was a slight association between familiarity with and participation in conservation programs. In comparison to women, men were more familiar with ESs, and this familiarity is linked to the effectiveness of learning sources. We conclude that learning sources are crucial for information dissemination. We recommend improving professional advice giving to boost participation in conservation programs and raise landowners’ awareness of ESs. Particular attention should be given to women, who are a growing segment of forest landowners’ population in the United States.
摘要自愿激励计划旨在鼓励对私有森林的保护和可持续管理。这项针对佐治亚州家庭森林所有者的研究使用了一种以性别为重点的方法来检验:学习来源在多大程度上预测了所有者对森林保护计划的熟悉程度;熟悉和参与保护计划之间的联系;以及土地所有者对森林生态系统服务的熟悉程度。我们分析了数据(N = 223),使用普通最小二乘法模型预测土地所有者对保护计划的熟悉程度,测试熟悉程度和参与保护计划之间的关联,并使用定性内容分析评估土地所有者对ES的熟悉程度。专业的森林管理建议和培训与熟悉保护计划有关,但性别(女性)是一个负面预测因素。熟悉和参与保护项目之间有轻微的联系。与女性相比,男性更熟悉ESs,这种熟悉程度与学习来源的有效性有关。我们的结论是,学习来源对信息传播至关重要。我们建议改进专业建议,以促进对保护计划的参与,并提高土地所有者对生态系统的认识。应特别注意妇女,她们在美国森林土地所有者人口中所占比例越来越大。

ABSTRACT An experimental trial was conducted to study the influence of a plant growth booster (PGB) on the seedling growth and quality parameters of Juniperus polycarpos in nursery conditions. One-year-old seedlings were applied with seven different doses of a PGB composed of humic acid (12%), fulvic acid (4.3%), seaweed extract (6.9%), and amino-based granules (6.8%) to study their effect on seedling growth and quality parameters. After 5 years in the nursery, maximum values of seedling growth parameters viz. shoot length (43.10 cm), root length (42.00 cm), collar diameter (5.93 mm), number of roots (41.00), fresh shoot biomass (18.83 g), fresh root biomass (5.87 g), total fresh biomass (24.71 g), dry shoot biomass (10.11 g), dry root biomass (3.06 g), and total dry biomass (13.17 g) were recorded in seedlings that were given 2.5 g PGB/seedling, as compared to the seedlings where no PGB was applied. The maximum value of quality parameters viz. volume index (1515.60) and quality index (1.25) was also observed in seedlings that received 2.5 g PGB/seedling. The study suggests the application of 2.5 g PGB per seedling for the production of quality planting stock of J. polycarpos in the nursery.
摘要通过试验研究了植物生长促进剂(PGB)在苗圃条件下对刺柏幼苗生长和质量参数的影响。用7种不同剂量的PGB对一年生幼苗进行施用,研究其对幼苗生长和质量参数的影响。PGB由腐殖酸(12%)、黄腐酸(4.3%)、海藻提取物(6.9%)和氨基颗粒(6.8%)组成。在苗圃中5年后,幼苗生长参数的最大值,即芽长(43.10 厘米),根长(42.00 cm),衣领直径(5.93 mm),根数(41.00),鲜梢生物量(18.83 g) ,鲜根生物量(5.87 g) ,总新鲜生物量(24.71 g) ,干茎生物量(10.11 g) ,干根生物量(3.06 g) 和总干生物量(13.17 g) 在给予2.5 g PGB/幼苗。质量参数的最大值,即体积指数(1515.60)和质量指数(1.25)也在接受2.5 g PGB/苗。该研究建议应用2.5 g PGB,用于在苗圃中生产优质的J.polycarpos种植料。

ABSTRACT Ailanthus excelsa, family Simaroubaceae is a deciduous, perennial, and fast-growing multipurpose tree commonly known as Tree of Heaven and is widespread in the semi-arid to temperate region of central India, southern India and Sri Lanka. Its leaves are used as fodder for cattle, goats, sheep, and camels. The tree has been widely explored in the ancient Indian traditional medicine system of Ayurveda to cure asthma, dysentery, pile, and leucorrhea. The plant has many pharmacological properties, viz. antihelminthic, antiamoebic, antiplasmodial, anti-inflammatory, antidiarrheal, antifertility, antioxidant, and antimicrobial. The plant is also known to have many phytochemicals such as alkaloids and flavonoids besides proteins, fatty acids, and carbohydrates. The present review first presents the state of knowledge regarding the geographical distribution, ecology, morphology, propagation methods, growth performances, and genetic diversity, of Ailanthus excelsa. It then summarizes what is known regarding its phytochemical components and their pharmaceutical properties. It finally explores the various uses (traditional medicine, bio-remediation, biofuel, feed-fodder, timber) of A. excelsa reported in the literature as well as its potential as an agroforestry tree crop. We believe this review will be useful for researchers aiming to develop a comprehensive understanding of this important tree species and for those wishing to explore more specific characteristics of the tree or/and of its uses.
摘要:臭椿科是一种落叶、多年生、快速生长的多用途树木,通常被称为天堂之树,广泛分布于印度中部、印度南部和斯里兰卡的半干旱至温带地区。它的叶子被用作牛、山羊、绵羊和骆驼的饲料。在古印度阿育吠陀传统医学体系中,这种树被广泛用于治疗哮喘、痢疾、痔疮和白带。该植物具有许多药理特性,即抗蠕虫、抗阿米巴、抗疟原虫、抗炎、止泻、抗生育、抗氧化和抗菌。众所周知,这种植物除了蛋白质、脂肪酸和碳水化合物外,还含有许多植物化学物质,如生物碱和类黄酮。本文首先介绍了关于臭椿的地理分布、生态学、形态、繁殖方法、生长性能和遗传多样性的知识现状。然后,它总结了关于其植物化学成分及其药用特性的已知情况。最后探讨了文献中报道的A.excelsa的各种用途(传统医学、生物修复、生物燃料、饲料、木材)及其作为农林树木作物的潜力。我们相信,这篇综述将有助于研究人员全面了解这一重要树种,也有助于那些希望探索树木或/及其用途的更具体特征的人。

ABSTRACT Ecosystem restoration remains high on development agendas worldwide. In the Sahel, including Senegal, knowledge gaps remain on how the underlying policy and regulations for rights and ownership influence farmers’ incentives for upscaling land restoration. We contribute to filling these gaps by i) analysing agroforestry related policy and regulations, and ii) assessing key stakeholders (foresters, animators, and farmers) perceptions in Kaffrine, Kaolack and Fatick regions using semi-structured interviews. The results show that tree rights and use procedures are determined by the Forestry Code and vary according to the status and location of the tree. However, the Forestry Code was found to be inappropriate for managing agroforestry systems where farmer managed natural regeneration (FMNR) is practiced, hence creating barriers to its adoption. Contrasting perceptions and potential solutions emerged. While the field animators and farmers find the tree use procedures burdensome and constraining for the practice of FMNR, most foresters find them not burdensome and appropriate for environmental protection. As solutions, animators and foresters suggest farmers’ sensitization, capacity building, and rewards, whereas the farmers call for an easing of tree use procedures and a reduction of taxes and permit fees. These results suggest farmer-centric and inclusive policy reform of tree rights in Senegal.
摘要:生态系统恢复仍然是世界发展议程上的重要内容。在包括塞内加尔在内的萨赫勒地区,关于权利和所有权的基本政策和法规如何影响农民扩大土地恢复的激励措施,仍然存在知识差距。我们通过i)分析农林相关政策和法规,以及ii)使用半结构化访谈评估Kaffrine、Kaolack和Fatick地区的关键利益相关者(林业工作者、动画师和农民)的看法,为填补这些空白做出了贡献。结果表明,树木权利和使用程序由《林业法》确定,并根据树木的状态和位置而有所不同。然而,《林业法》被发现不适合管理实行农民管理的自然再生(FMNR)的农林系统,因此为其采用设置了障碍。出现了不同的看法和潜在的解决方案。虽然实地动画师和农民发现树木使用程序对FMNR的实践来说是繁重和约束的,但大多数林业工作者发现它们并不繁重,不适合环境保护。作为解决方案,动画师和林业工作者建议农民提高认识、能力建设和奖励,而农民则呼吁放宽树木使用程序,降低税收和许可费。这些结果表明,塞内加尔对树木权利进行了以农民为中心的包容性政策改革。

Does secured forest land tenure enhance forest dwellers' food security? Empirical evidence from West Bengal, India 有保障的林地权属是否能提高森林居民的粮食安全?来自印度西孟加拉邦的经验证据
Q4 ENVIRONMENTAL STUDIES Pub Date : 2023-05-28 DOI: 10.1080/14728028.2023.2217838

ABSTRACT Under the Forest Rights Act 2006, the government of India has recognised the Individual Forest Rights (IFR) of forest dwellers that formalise the de jure land tenure over forest land. This is expected to incentivise owners to invest and take better care of their forest land which, in turn, is assumed to improve households’ income and financial access and thereby reduce their food insecurity. Using the primary data collected from 300 IFR beneficiary households in Bankura district of the Indian state of West Bengal and the ordinal logistic regression model, this paper identifies and analyses the determinant factors influencing household food insecurity. Results show that larger IFR land size areas, higher education levels of the household head, and higher annual income are associated with a significant reduction in food insecurity. On the contrary, larger household sizes, higher dependency ratios, and the occurrence of crop damage are associated with a highly significant increase in food insecurity. Hence, it is suggested that in order to help reduce households’ food insecurity among forest dwellers in the state, the assignment of IFR land area of sufficient size to forest dwellers’ households may further be encouraged.
根据《2006年森林权利法案》,印度政府承认森林居民的个人森林权利(IFR),使森林土地的法定土地所有权正规化。预计这将激励所有者投资并更好地照顾他们的林地,这反过来又被认为可以改善家庭收入和财政渠道,从而减少他们的粮食不安全状况。本文利用从印度西孟加拉邦班库拉地区300户IFR受益家庭收集的原始数据和有序logistic回归模型,识别并分析了影响家庭粮食不安全的决定因素。结果表明,较大的IFR土地面积、户主较高的教育水平和较高的年收入与粮食不安全状况的显著减少有关。相反,更大的家庭规模、更高的抚养比率和作物受损的发生与粮食不安全的显著增加有关。因此,建议为帮助减少该邦森林居民家庭的粮食不安全,可进一步鼓励向森林居民家庭分配足够规模的IFR土地面积。

ABSTRACT Local communities are relocated from protected areas to lessen human activities that jeopardize biodiversity conservation. Buxa Tiger Reserve (BTR) has a large number of people living in the core tiger habitat area and the relocation programmes introduced have not achieved the goal of complete relocation of people. Using both quantitative household data and qualitative and sustainable livelihood framework, this study aimed to assess the livelihood conditions of the forest villagers and understand factors influencing their attitudes towards relocation from the core area of the BTR. The results of binary logistic regression show that the age of the household head, education of the household head, family size, elderly dependency, forest dependency, income from ecotourism and forest department work, degradation of the nearby forest, and frequency of human-wildlife conflicts are the key determinants factors influencing the household decision to relocation. The study observed that most of the households were reluctant to relocate because of the low compensation amount, job insecurity and emotional bonding with the place where they feel happy and comfortable. In contrast, the non-availability of proper infrastructure facilities, lack of work, problems of human-wildlife conflicts, and children's education have appeared to be the key factors of alacrity to relocate.
摘要:当地社区从保护区搬迁,以减少危害生物多样性保护的人类活动。布克萨老虎保护区(BTR)有大量的人生活在老虎的核心栖息地,引入的搬迁计划没有实现完全搬迁的目标。本研究利用定量的家庭数据和定性和可持续的生计框架,旨在评估森林村民的生计状况,并了解影响他们从BTR核心区搬迁态度的因素。二元逻辑回归结果表明,户主年龄、户主教育程度、家庭规模、老年人依赖性、森林依赖性、生态旅游和林业部门工作收入、附近森林的退化以及人类与野生动物冲突的频率是影响家庭搬迁决策的关键决定因素。研究观察到,大多数家庭不愿意搬迁,因为补偿金额低、工作不安全以及与他们感到幸福和舒适的地方的情感联系。相比之下,缺乏适当的基础设施、缺乏工作、人类与野生动物冲突的问题以及儿童的教育似乎是迅速搬迁的关键因素。

ABSTRACT Domestication of baobab (Adansonia digitata L.), is imperative to ensure its sustainable utilization. A key issue in domesticating is the knowledge on cultural practices including nursery management. However, much is not known regarding nursery requirements for baobab. The objective of this study therefore, was to assess the effect of shade regimes (partial shade and full sun) and growth media (garden soil and soilless medium) on the performance of baobab seedlings. The data collected included the number of leaves, plant height, stem diameter and chlorophyll content. A two-way ANOVA showed that, seedlings raised in soilless medium placed in the full sun performed best after nine weeks compared with the other treatments. The best seedlings significantly (p < 0.05) developed more leaves (34 pcs)   as well as largest stem diameter (10.4 mm) and had higher chlorophyll content (33.2 SPAD value). Raising baobab in soilless medium in full sun resulted in faster growth in height (35 cm), however, it was not significantly better compared to the other treatments. It is suggested that baobab seedlings should be grown in soilless medium made up of poultry manure, cow-dung and sawdust in full sun for better performance.
摘要为了保证猴面包树的可持续利用,对其进行驯化势在必行。驯化过程中的一个关键问题是对包括托儿所管理在内的文化实践的了解。然而,关于猴面包树的苗圃要求,目前还知之甚少。因此,本研究的目的是评估遮荫制度(部分遮荫和全日照)和生长培养基(花园土壤和无土培养基)对猴面包树幼苗性能的影响。收集的数据包括叶片数量、株高、茎直径和叶绿素含量。双向方差分析显示,与其他处理相比,在阳光充足的无土培养基中培养的幼苗在九周后表现最好。最佳幼苗显著(p < 0.05)长出更多的叶子(34片)   以及最大阀杆直径(10.4 mm),并具有较高的叶绿素含量(33.2 SPAD值)。在阳光充足的无土培养基中饲养猴面包树可使其身高增长更快(35 cm),但与其他处理相比并没有显著改善。建议猴面包树幼苗应在由家禽粪便、牛粪和锯末组成的无土培养基中充分阳光下生长,以获得更好的性能。
