Introduction : La pratique de la dépigmentation cosmétique volontaire est de plus en plus adoptée par les jeunes filles. Ce phénomène de " mode " révèle un certain aspect socio-anthropologique qui assimile la couleur noire de la peau à une vision négative et inférieure de l'être humain. Objectif: l’objectif est de comprendre ce qui motive les jeunes filles scolarisées à s’adonner à une telle pratique plus spécifquement d‘évaluer leurs connaissances, attitudes et pratiques face à la dépigmentation. Méthode : Il s'agit d'une étude transversale réalisée entre Avril et Mai 2023 qui a concerné 1039 étudiantes des écoles et universités du département des Collines sélectionnées par sondage aléatoire simple à plusieurs degrés. Résultats : La moitié des filles enquêtées savaient que la dépigmentation est l’utilisation de produits chimiques dans le but d’éclaircir la peau. Pour la plupart (82,9%) d’entre elles, la couleur de la peau était une représentation de critère de beauté. Une femme à peau claire avait plus de valeur qu’une femme à peau noire selon 43,0% des enquêtées. 78,2% avaient adopté la pratique de la dépigmentation volontaire et le rythme d’application était biquotidien chez 70,6% d’entre elles.  La principale motivation des filles était d’uniformiser le teint. Conclusion : La dépigmentations est un phénomene bien connu des élèves et étudiantes du département des collines.  La plupart des enquêtées pratique la dépigmentation et le critère de beauté est utilisé pour justifier le phénomène.   Introduction: the practice of voluntary cosmetic depigmentation is increasingly adopted by young girls. This "fashion" phenomenon reveals a certain socio-anthropological aspect that assimilates the black color of the skin to a negative and inferior vision of the human being. Objective:  was to understand what motivates young girls at school to engage in such a practice more specifically evaluate their knowledge, attitudes, and practices regarding depigmentation. Method: This is a cross-sectional study carried out between April and May 2023 which involved 1039 female students from schools and universities in the Collines department selected by simple multistage random sampling. Results: Half the girls surveyed knew that depigmentation is the use of chemicals to lighten the skin. For the majority (82.9%) of them, skin color was a representation of beauty criteria. A light-skinned woman was more valuable than a dark-skinned woman, according to 43.0% of respondents. 78.2% have adopted the practice of voluntary depigmentation, and 70.6% of them apply their products twice a day.  The girls' main motivation was to even out their skin color. Conclusion: Depigmentation is well known among pupils and students in the hill district.  Most of those surveyed practice depigmentation and the criterion of beauty is used to justify the phenomenon.
导言:越来越多的年轻女孩采用自愿脱色美容的做法。这种 "时尚 "现象揭示了某种社会人类学方面的问题,即把黑色皮肤与消极和低劣的人类观相联系。目的:旨在了解是什么促使年轻女学生参与这种做法,更具体地说,是评估她们对去色斑的认识、态度和做法。方法:这项横断面研究于 2023 年 4 月至 5 月间进行,通过多阶段简单随机抽样,从科林斯省的中小学和大学中选取了 1039 名女学生参与调查。结果:半数受访女生知道脱色就是使用化学产品美白皮肤。对她们中的大多数人(82.9%)来说,肤色是美丽标准的代表。43.0% 的受访者认为,皮肤白皙的女性比皮肤黝黑的女性更有价值。78.2% 的受访者采取了自愿脱色的做法,70.6% 的受访者每天使用两次脱色产品。 女孩们的主要动机是使肤色均匀。结论:脱色斑是高年级学生中众所周知的现象。 大多数接受调查的女生都有去色斑的行为,并以 "美 "为标准为这一现象辩解。 导言:越来越多的年轻女孩自愿进行脱色美容。这种 "时尚 "现象揭示了某种社会人类学方面的问题,即把黑色皮肤与消极和低劣的人类观相联系。目的:了解是什么促使在校少女采用这种做法,更具体地说,评估她们对脱色的认识、态度和做法。方法:这是一项横断面研究,于 2023 年 4 月至 5 月间进行,通过简单的多阶段随机抽样,从科林斯省的中小学和大学中选取了 1039 名女学生参与调查。结果:半数受访女生知道脱色是使用化学物质美白皮肤。对她们中的大多数人(82.9%)来说,肤色是美丽标准的代表。43.0% 的受访者认为,肤色浅的女性比肤色深的女性更有价值。78.2% 的受访者采取了自愿脱色的做法,其中 70.6% 的受访者每天使用两次脱色产品。 女孩们的主要动机是使自己的肤色均匀。结论:在山区的中小学生中,色素沉着已广为人知。 大多数受访者都有去色斑的行为,并以美丽为标准来证明这种现象的合理性。

Entrepreneurship is globally seen as a tool for job creation, contributing to the stability and economic development of nations. This is why the governments of many nations, including Ghana, put up initiatives to promote entrepreneurial activities. This paper focuses on assessing equity crowdfunding as an alternative source of generating fund for entrepreneurial projects in Ghana. A combination of qualitative and quantitative approaches were used in conducting this study in the Tema Municipality of the Greater Accra Region. A sample size of 149 entrepreneurs in various industries, 118 investors, and 90 respondents acting as both entrepreneurs and investors were chosen through purposive sampling method. Data were collected through the use of questionnaires and analyzed using descriptive statistics, employing tables and graphs. The results of the study showed that most entrepreneurs and investors had heard of equity crowdfunding but very few understood the operations of this type of funding. Also, it became evident that the investors and entrepreneurs had inadequate knowledge and understanding about crowdfunding adoption in Ghana. The study showed that equity crowdfunding is capable of bridging the funding gap and, therefore, is a suitable alternative in generating funds for entrepreneurship in Ghana. It is recommended that equity crowdfunding should be included as a source of funding in entrepreneurship curriculum. Also, policies should be made by government to establish regulations that will protect all the parties involved in equity crowdfunding.
创业在全球被视为创造就业机会、促进国家稳定和经济发展的工具。因此,包括加纳在内的许多国家的政府都提出了促进创业活动的倡议。本文重点评估股权众筹作为加纳创业项目的另一种资金来源。本研究在大阿克拉地区的特马市进行,采用了定性和定量相结合的方法。通过有目的的抽样方法,选取了 149 名不同行业的创业者、118 名投资者和 90 名既是创业者又是投资者的受访者作为样本。通过问卷收集数据,并使用描述性统计、表格和图表进行分析。研究结果表明,大多数企业家和投资者都听说过股权众筹,但很少有人了解这种融资方式的运作。此外,投资者和企业家对加纳采用众筹的认识和理解也明显不足。研究表明,股权众筹能够弥补资金缺口,因此是为加纳创业提供资金的合适选择。建议将股权众筹作为一种资金来源纳入创业课程。此外,政府应制定政策,建立法规,保护股权众筹的所有相关方。

Ce travail avait pour objectif de déterminer la typologie et la source probable de recharge des aquifères rencontrés à Bonoua en vue d’une meilleure gestion de ceux-ci. Les travaux ont utilisé des échantillons de forages prélevés à Bonoua au Sud-Est de la Côte d’Ivoire. L’étude lithologique a révélé des sables, des argiles sableuses et des argiles bariolées. Les sables constituent l’essentiel des aquifères. La détermination des indices d’évolution totale (Nt) et segmentaire (Ns) a illustré trois aquifères. La variation de ces indices a révélé une direction NW-SE des paléocourants. Les indices Ns des sables montrent qu’ils ont subi un long transport (64 % à 86 %). Le principal aquifère se situe à 64,5 m en moyenne. Il est surmonté par un niveau imperméable (toit) d’argile bariolée et enregistre les meilleures arrivées d’eau. Il est dominé de sables grossiers (66,66 % à 85,71 %) à très grossiers avec une forme subarrondie (16 % à 53,57 %) et arrondies (13,04 % à 40 %). Les particules fines piégées par les grossières à l’équilibre lors du dépôt sont toutes les deux issues d’un courant cogénétique. Ces sédiments transportés majoritairement par saltation et déposés généralement selon un faciès logarithmique (Nt = 0) et rarement parabolique (0 ˂ Nt ˂ 1) sont très bien classés (83,33 % à 100 %). Cette étude a permis d’identifier deux nouveaux faciès qui sont le faciès subparabolique (0,05 ≤ Nt ≤ 0,09) et le faciès linéaire (Nt = 1). Le faible pourcentage de fine offre à l’aquifère une bonne porosité et une bonne perméabilité ainsi qu’une bonne transmissivité de l’eau souterraine. Ce travail révèle donc qu’un seul aquifère existe dans cette localité mais se présente en bicouche séparée par de l’argile bariolée qui constitue le toit de cette nappe captive exploitée dans le zone. L’écoulement souterrain de direction NW-SE suppose que l’eau stockée à Bonoua proviendrait du fleuve Comoé qui coule en direction de la localité de Bassam. D’où la nécessité de protéger les cours d’eau rencontrées dans la localité de Bassam ainsi qu’au Nord de la zone d’étude afin garantir l’eau à Bonoua.   The objective of this study was to determine the typology and likely recharge source of the aquifers found in Bonoua, aiming to enhance their management. Samples from boreholes in Bonoua, located in southeastern Côte d'Ivoire, were analyzed. The lithological examination revealed the presence of sands, sandy clays, and variegated clays, with sands comprising the majority of the aquifers. Analysis of total (Nt) and segmental (Ns) evolution indices highlighted the presence of three distinct aquifers. The fluctuation in these indices indicated a prevailing NW-SE direction of paleocurrents. The Ns indices of the sands indicate significant long-distance transport (ranging from 64% to 86%). The primary aquifer is typically found at an average depth of 64.5 meters. It is capped by an impermeable layer (roof) of variegated clay, leading to optimal water inflow. The predominant sands r
这项工作的目的是确定博努阿含水层的类型和可能的补给来源,以便改善含水层的管理。样本取自科特迪瓦东南部博努阿的钻孔。岩性研究揭示了砂土、砂质粘土和杂色粘土。砂土占含水层的大部分。总演化指数(Nt)和分段演化指数(Ns)的测定显示了三个含水层。这些指数的变化揭示了古海流的西北-东南方向。泥沙的 Ns 指数显示,它们经历了长时间的搬运(64%-86%)。主含水层平均深度为 64.5 米。它的顶部是不透水的杂色粘土层(顶板),记录了最好的进水情况。含水层主要由粗砂(66.66%-85.71%)至极粗砂组成,呈亚圆形(16%-53.57%)和圆形(13.04%-40%)。沉积过程中处于平衡状态的粗颗粒所夹带的细颗粒都是共生流的结果。这些沉积物主要通过盐渍化搬运,一般沉积在对数面(Nt = 0)上,极少数沉积在抛物面(0 ˂ Nt ˂ 1)上,分类非常准确(83.33%-100%)。这项研究发现了两个新的面层:亚抛物面(0.05 ≤ Nt ≤ 0.09)和线形面(Nt = 1)。由于细粒比例较低,含水层具有良好的孔隙度和渗透性,以及良好的地下水渗透性。因此,这项研究表明,该地区存在一个单一的含水层,但以双层的形式存在,并被杂色粘土分隔开来,而杂色粘土则构成了该地区所开采的承压水层的顶板。西北-东南走向的地下水流表明,博努阿储存的水来自流向巴萨姆的科莫埃河。因此,有必要保护巴萨姆和研究区北部的水道,以保证博努阿的供水。 这项研究的目的是确定博努阿含水层的类型和可能的补给来源,以加强对含水层的管理。对位于科特迪瓦东南部博努阿的钻孔样本进行了分析。岩性检查显示,含水层中存在沙土、沙质粘土和杂色粘土,其中沙土占大多数。对总演化指数(Nt)和分段演化指数(Ns)的分析突出表明存在三个不同的含水层。这些指数的波动表明古海流的主要方向为西北-东南。泥沙的 Ns 指数表明存在明显的长距离运移(从 64% 到 86%)。原生含水层的平均深度通常为 64.5 米。它被一层不透水的杂色粘土层(顶板)所覆盖,从而使水流达到最佳状态。主要沙粒从粗沙(66.66% 至 85.71%)到极粗沙不等,呈现出近圆形(16% 至 53.57%)和圆形(13.04% 至 40%)的特征。在沉积平衡过程中,被粗颗粒困住的细颗粒都来自共生流。这些沉积物主要通过盐渍化作用迁移,通常以对数面(Nt = 0)沉积,偶尔也以抛物面(0 ˂ Nt ˂ 1)沉积,其分类准确率很高(从 83.33% 到 100% 不等)。此外,这项研究还发现了两种新的岩相:亚抛物线岩相(0.05 ≤ Nt ≤ 0.09)和线性岩相(Nt = 1)。由于细粒比例较低,含水层具有良好的孔隙度、渗透性和地下水渗透率。因此,这项研究证实了该地区存在一个单一的含水层,该含水层呈双层结构,由变色粘土隔开,是该地区已开采的自生含水层的顶板。西北-东南走向的地下水流模式表明,博努阿蓄水源于流向巴萨姆的科莫埃河。因此,必须保护巴萨姆附近和研究区北部的水道,以确保博努阿的可靠供水。

Dans le contexte de rareté des ressources forestières, évaluer le degré d’exploitation des produits forestiers non ligneux est crucial pour comprendre les pressions exercées sur les produits forestiers non ligneux et in fine de mettre en place des stratégies visant une exploitation rationnelle et durable des produits forestiers non ligneux. Cette étude a pour objectifs d’analyser la dynamique d’exploitation des produits forestiers non ligneux. Un suivi de l’exploitation des produits forestiers non ligneux a été réalisé chez 260 exploitants répartis en 30 groupements. Un questionnaire a été utilisé pour la collecte des données complémentaires et ont été administrés auprès de 150 producteurs au niveau de quatre communes Les résultats montrent qu’entre 2012 et 2018, le volume d’exploitation du pain de singe est passé de 20,087 tonnes à 88,457 tonnes, de 1,19 T à 45,231 tonnes pour le Saba. Celui du miel est passé de 4 354 litres en 2012 à 6 694 litres, de10 280 litres à 35 563 litres pour l’huile de palme. Quant au Néré, son exploitation est passée de 79, 996 tonnes en 2012 à 263, 141 tonnes. La commercialisation des produits exploités a permis de générer plus de 208 859 000 millions de FCFA par an. Il ressort des enquêtes de perception que l’ensemble des produits forestiers subissent une forte pression et que leur disponibilité est de plus en plus faible. Dès lors, des stratégies résilientes sont à adopter allant de l’exploitation contrôlée à la conservation de ces ressources.   In the context of scarce forest resources, assessing the degree of exploitation of non-timber forest products is crucial to understanding the pressures exerted on non-timber forest products and, ultimately, to implementing strategies aimed at rational and sustainable exploitation of non-timber forest products. The aim of this study is to analyze the dynamics of non-timber forest product exploitation. Non-timber forest product harvesting was monitored among 260 farmers in 30 groups. A questionnaire was used to collect additional data and was administered to 150 producers in four communes. The results show that between 2012 and 2018, the volume of monkey bread harvested rose from 20.087 tonnes to 88.457 tonnes, and from 1.19 T to 45.231 tonnes for Saba. Honey production rose from 4,354 liters in 2012 to 6,694 liters, and palm oil from 10,280 liters to 35,563 liters. Néré production rose from 79.996 tonnes in 2012 to 263.141 tonnes. The marketing of harvested products generated more than 208,859,000 million FCFA per year. Perception surveys show that all forest products are under heavy pressure and that their availability is becoming increasingly limited. Resilient strategies must therefore be adopted, ranging from controlled harvesting to conservation of these resources.
鉴于森林资源的稀缺性,评估非木材森林产品的开发程度对于了解非木材森林产品所面临的压力以及最终实施旨在合理和可持续开发非木材森林产品的战略至关重要。本研究旨在分析非木材林产品开发的动态。对 30 个小组的 260 名农民的非木材林产品开发情况进行了监测。结果显示,2012 年至 2018 年间,猴面包的收获量从 20,087 吨增至 88,457 吨,萨巴面包的收获量从 1,19 吨增至 45,231 吨。蜂蜜产量从 2012 年的 4354 升增加到 6694 升,棕榈油从 10280 升增加到 35563 升。内酯产量从 2012 年的 79 996 吨增至 263 141 吨。这些产品的销售收入每年超过 2,088.59 亿非洲金融共同体法郎。认知调查显示,所有林产品都面临着巨大压力,其供应量越来越有限。因此,必须采取有弹性的战略,从控制开采到保护这些资源。 在森林资源稀缺的背景下,评估非木材林产品的开发程度对于了解非木材林产品所面临的压力以及最终实施合理和可持续开发非木材林产品的战略至关重要。本研究旨在分析非木材林产品开发的动态。对 30 个小组的 260 名农民的非木材林产品采伐情况进行了监测。为收集更多数据,还对 4 个乡镇的 150 名生产者进行了问卷调查。结果显示,2012 年至 2018 年间,猴面包的收获量从 20.087 吨增至 88.457 吨,萨巴从 1.19 吨增至 45.231 吨。蜂蜜产量从2012年的4354升上升到6694升,棕榈油从10280升上升到35563升。内雷产量从 2012 年的 79.996 吨增至 263.141 吨。采伐产品的销售收入每年超过 2,088.59 亿非洲金融共同体法郎。认知调查显示,所有林产品都面临着巨大压力,其供应量日益有限。因此,必须采取弹性战略,从控制采伐到保护这些资源。

Entrepreneurial marketing (EM) is a dynamic and innovative approach to marketing that is particularly well-suited for startups and small businesses. Thus, the study focuses on Sudanese SMEs in order to assist them in achieving profitability, sustainability, and competitive advantage in the long term. Consequently, our objectives are to develop the research pre-model and to explore in depth how entrepreneurs, managers, and employees of SMEs in Khartoum-Sudan are familiar with the concepts of the research pre-model, and how they can employ and take advantage of study concepts. To achieve these objectives, we relayed on the qualitative method an inductive approach to test the validity and to develop the research pre-model. Hence, we have designed an open-ended question scenario and conducted a certain interview utilizing multiple qualitative methods to gather the data from the purposive sample which consists of (15) individuals. We have divided the scenario into three main parts of questions, first open-ended questions about EM, in this regard the most important question that has been asked to the interviewees was “What are the factors/dimensions that comes to your mind when you hear about EM”? Secondly, open-ended questions about technological capabilities TCPs. “The commonly thought view of TCPs proposes that firms with strong technological capability can rapidly identify technological opportunities and the value of technological resources and utilizing modern equipment, in this scope benefits of entrepreneurial marketing should therefore be enhanced by a firm’s high technological capability”. e.g., “What are the expected advantages that will be rewarded by employing TCPs in SMEs”? Finally, we have grouped data into concepts, categories, and themes and then utilized a manual-thematic analysis as a method for identifying, analyzing, and interpreting patterns within data. In this scope we have analyzed the data and interpreted the results within three main themes. Accordingly, significant new dimensions have been discovered and generated which led to our final developed and adapted research model.
企业家营销(EM)是一种充满活力和创新的营销方法,尤其适合初创企业和小型企业。因此,本研究以苏丹中小型企业为重点,以帮助它们实现盈利、可持续性和长期竞争优势。因此,我们的目标是开发研究前模型,深入探讨苏丹喀土穆中小企业的企业家、经理和员工如何熟悉研究前模型的概念,以及他们如何运用和利用研究概念。为了实现这些目标,我们采用了归纳法这一定性方法,以检验研究前模型的有效性和发展研究前模型。因此,我们设计了一个开放式问题情景,并利用多种定性方法进行了一定的访谈,以便从由(15)个人组成的目的性样本中收集数据。我们将情景问题分为三个主要部分,首先是关于电磁的开放式问题,在这方面,我们向受访者提出的最重要的问题是 "当你听到电磁时,你会想到哪些因素/方面"?第二,关于技术能力 TCPs 的开放式问题。"对 TCPs 的普遍看法是,技术能力强的企业能迅速发现技术机会和技术资源的价值,并能利用现代化设备,因此,在这一范围内,企业营销的效益应通过企业的高技术能力来提高。"例如,"中小企业采用 TCPs 有哪些预期优势"?最后,我们将数据归类为概念、类别和主题,然后利用人工专题分析作为识别、分析和解释数据模式的方法。在此范围内,我们对数据进行了分析,并根据三大主题对结果进行了解释。因此,我们发现并产生了重要的新维度,并最终开发和调整了研究模型。

The Effect of Innovation on Competitiveness in the Food Processing Industry of Cameroon: A Mediating Effect of Quality Management 创新对喀麦隆食品加工业竞争力的影响:质量管理的中介效应
Pub Date : 2024-02-29 DOI: 10.19044/esj.2024.v20n4p129
Baninla Nicholas, M. Sama, Nwahanye Emmanuel
With the intensification of national and global competition, the focus of companies is now on how to achieve competitive advantage. With globalisation, Cameroon’s industry is facing specific difficulties such as unchecked competition from imports, internal weaknesses in output, low technology acquisition as well as poor links between industry and the institutional sector, making competition a problem for them. This led to the foundation of studies on innovation and competitiveness, but at this point, there are still inconclusive results. This paper focuses on examining the effect of innovation on competitiveness in the food processing industry of Cameroon, with a specific emphasis on the mediating effect of quality management. This study adopted the cross-sectional research design for its investigation. The primary source of data was used for this study, as it was current. This primary data was collected through the distribution of questionnaires to the respondents. Innovation in this study was captured in terms product, process, market, and organisational innovations. Quality management on the other hand was captured in terms of commitment to quality, employee involvement, customer focus, process monitoring, incentives, and recognition. In relation to competitiveness, the study focused on productivity, output growth, and market share. Data was collected from 335 managers of food processing companies drawn randomly after stratification from a population of 2564 food processing companies operating in Cameroon. This includes Douala, Yaounde, Ngaoundere, Buea, Bafoussam, Maroua, and Bertoua with 201, 40, 34, 3, 30, 17, and 10 as corresponding sample proportions respectively. Inferential statistics was used during the analysis of the data, specifically using Baron and Kenny’s approach of testing the mediation hypothesis. Based on the results, there were traces of positive and significant direct effects of product, process, and organisational innovations on competitiveness. On the other hand, market innovation was insignificant. In terms of the indirect effect, the study revealed a partial mediation of quality management in the effect of product innovation on competitiveness. Quality management, however, had no mediating role on other dimensions of innovation (process, market, and organisational) and competitiveness.
随着国内和全球竞争的加剧,企业现在的重点是如何取得竞争优势。随着全球化的发展,喀麦隆的工业面临着一些特殊的困难,如进口产品的无序竞争、内部产出不足、技术获取能力低以及工业与机构部门之间的联系不紧密,这些都使竞争成为喀麦隆工业面临的问题。因此,有关创新和竞争力的研究应运而生,但目前仍无定论。本文重点研究创新对喀麦隆食品加工业竞争力的影响,特别强调质量管理的中介效应。本研究采用横截面研究设计进行调查。本研究采用了原始数据来源,因为它具有时效性。原始数据是通过向受访者发放调查问卷收集的。本研究中的创新包括产品创新、流程创新、市场创新和组织创新。另一方面,质量管理包括对质量的承诺、员工参与、以客户为中心、过程监控、激励和认可。在竞争力方面,研究侧重于生产率、产出增长和市场份额。数据收集自喀麦隆 2564 家食品加工企业中经过分层随机抽取的 335 名食品加工企业管理人员。其中包括杜阿拉、雅温得、恩冈代雷、布埃亚、巴富萨姆、马鲁阿和贝尔图阿,相应的样本比例分别为 201、40、34、3、30、17 和 10。在分析数据时使用了推断统计法,特别是使用巴伦和肯尼的方法来检验中介假设。结果表明,产品创新、流程创新和组织创新对竞争力有显著的正向直接影响。另一方面,市场创新并不显著。在间接效应方面,研究显示质量管理对产品创新对竞争力的影响具有部分中介作用。然而,质量管理对其他方面的创新(流程、市场和组织)和竞争力没有中介作用。

Bertal Yassine, Ben Brahim Youssef
This paper focuses on analyzing the temporal variability of rainfall and rainfall trends using a statistical analysis of rainfall data in the Melloulou watershed for a half-century chronicle (1970-2020). The objective of this study is to extract all the rainfall characteristics and the rainfall variability during this period to determine the rainfall trends. The working method is based on a statistical approach to detect the climatic characteristics of the Melloulou basin. The study of the standardized precipitation index (SPI) and the rainfall deficit index (RDI) showed the alternation of very long dry periods with wet periods. The Mann-Kendall test under the RStudio also showed a decreasing rainfall trend.

Le Sénégal, à l’instar des autres pays sahéliens, est confronté à la dégradation de ses espaces forestiers due à un ensemble de facteurs tels que : les défrichements agricoles, les feux tardifs, l’exploitation anarchique, etc. Ce phénomène est plus accentué dans la région de Diourbel où l’un des très rares poumons verts se trouve dans le site du Centre National de Recherches Agronomiques de Bambey (CNRA). Cette étude avait comme objectifs de caractériser et d’estimer le potentiel des ligneux dans cette formation forestière dans le but de donner formuler des recommandations. Un inventaire systématique sur 103 placettes de 50 X 50 m a été réalisé en 2018. Les paramètres recherchés ont été : la richesse spécifique, la densité du peuplement, la surface terrière, le volume de bois, le couvert aérien, la régénération, la structure horizontale et verticale, les observations sur l’émondage, le vieillissement, etc. Ainsi, 28 espèces appartenants à 13 familles ont été recensées. Les familles des Mimosaceae (28,57%) et des Combretaceae (17,86%) dominent la végétation. Pour les individus adultes, la densité est de 98 individus/ha, dominée par Acacia seyal, tandis que la régénération s’élève à 581 plantules/ha, dominée par Combretum aculeatum. La surface terrière du peuplement est estimée à 2,12 m2/ha, le couvert aérien (3223,08 m2/ha) et le volume (13,83 m3/ha). La distribution du peuplement par classe de diamètre et de hauteur révèle la prédominance de la strate arbustive. Les observations ont montré la présence de pratiques anthropiques qui pourraient contribuer à la régression de la dynamique du peuplement par la diminution du couvert végétal et la disparition de certaines espèces (Deterium microcarpum, Pterocarpus erinaceus et Sterculia setigera) constatée dans cette formation.  Ces résultats montrent l’urgence de mettre en place une stratégie de gestion en étroite collaboration avec les communautés pour la conservation et la restauration du couvert végétale de cette formation boisée de 149 ha.   Senegal, like other Sahelian countries, is faced with the degradation of its forest areas due to a combination of factors such as agricultural clearing, late fires, uncontrolled logging, etc. This phenomenon is more pronounced in the Diourbel region, where one of the very few green lungs is located on the site of the Centre National de Recherches Agronomiques Bambey (CNRA). This phenomenon is more pronounced in the Diourbel region, where one of the very few green lungs can be found on the site of the “Centre National de Recherches Agronomiques de Bambey” (CNRA). The objectives of this study were to characterize and estimate the potential of woody species in this forest formation, to formulate recommendations. A systematic inventory of 103 50 x 50 m plots was carried out in 2018. The parameters investigated were: species richness, stand density, basal area, wood volume, aerial cover, regeneration, horizontal and vertical structure, observations on pruning, agin
与其他萨赫勒国家一样,塞内加尔也面临着林区退化的问题,这是由多种因素共同造成的,如:农业开垦、后期火灾、无节制砍伐等。这种现象在 Diourbel 地区更为明显,该地区为数不多的绿肺之一就位于班贝国家农业研究中心(CNRA)所在地。这一现象在 Diourbel 地区更为明显,该地区为数不多的绿肺之一就位于班贝国家农业研究中心(CNRA)所在地。这项研究的目的是对这一森林地貌的特点和木本物种的潜力进行评估,以便提出建议。2018 年对 103 块 50 x 50 米的地块进行了系统清查。研究参数包括:物种丰富度、林分密度、基部面积、木材蓄积量、空中植被、再生、水平和垂直结构、修剪观察、树龄等。共确定了 13 个科 28 个物种。植被以含羞草科(28.57%)和梳形科(17.86%)为主。成年树的密度为 98 棵/公顷,主要是相思树,而再生树的密度为 581 棵/公顷,主要是 Combretum aculeatum。据估计,林分的基部面积为 2.12 平方米/公顷,空中覆盖面积为 3223.08 平方米/公顷,体积为 13.83 立方米/公顷。林分的直径和高度分布显示灌木层占主导地位。观察结果表明,人类活动的存在可能导致植被覆盖率降低和某些物种(Deterium microcarpum、Pterocarpus erinaceus 和 Sterculia setigera)的消失,从而导致林分动态下降。 这些结果表明,迫切需要与社区密切合作,实施一项管理战略,以保护和恢复这片 149 公顷林地的植物覆盖率。 与其他萨赫勒国家一样,塞内加尔也面临着林区退化的问题,这是由农业开垦、后期火灾、无节制砍伐等多种因素造成的。这一现象在 Diourbel 地区更为明显,该地区为数不多的绿肺之一就位于班贝国家农业研究中心(CNRA)所在地。这一现象在 Diourbel 地区更为明显,该地区为数不多的 "绿肺 "之一就位于 "班贝国家农业研究中心"(CNRA)所在地。这项研究的目的是确定该森林地貌中木本物种的特征和潜力,并提出相关建议。2018 年,对 103 块 50 x 50 米的地块进行了系统清查。调查的参数包括:物种丰富度、林分密度、基部面积、木材蓄积量、空中植被、再生、水平和垂直结构、修剪观察、老化等。共调查了隶属于 13 个科的 28 个物种。在这些科中,含羞草科(28.57%)和梳形科(17.86%)在植被中占主导地位。成年树的密度为 98 株/公顷,主要是相思树,而再生树的密度为 581 株/公顷,主要是 Combretum aculeatum。据估计,林分的基部面积为 2.12 平方米/公顷,空中覆盖面积为 3223.08 平方米/公顷,体积为 13.83 立方米/公顷。林分直径和高度等级的分布显示灌木层占主导地位。观察结果表明,人类活动可能导致植被覆盖率下降和某些物种(Deterium microcarpum、Pterocarpus erinaceus 和 Sterculia setigera)消失,从而导致林分动态下降。这些结果表明,迫切需要与社区密切合作,实施一项管理战略,以保护和恢复这片 149 公顷林地的植物覆盖率。
