Cet article contribue à une meilleure connaissance de l’importance socioéconomique du maraichage au Lac Rose dans la zone périurbaine de Dakar. La méthodologie mixte (quantitative et qualitative) de collecte de données a été adoptée à cet effet. Elle a permis d’effectuer une analyse descriptive de la situation socioéconomique des acteurs maraichers. Les résultats révèlent une grande importance de cet écosystème lacustre parce que participant activement dans l’approvisionnement en produits maraichers pour la population locale et le marché urbain dakarois. En plus, le maraichage garantit des revenus substantiels aux exploitants qui s’y adonnent. Le revenu moyen par maraicher sur une récolte est de 893 750 F FCA (1 375 Euro) tandis que le revenu plus élevé sur une récolte est 3 000 000 F CFA (4 615,3 Euro). Cet article montre un fort intérêt socioéconomique de l’écosystème du Lac Rose, ce qui doit amener à préserver cet espace naturel de l’urbanisation galopante en cours dans la zone.

Combretum micranthum (kinkeliba) is one of the most used medicinal plants in Senegal. However, its commercialization is poorly studied. The objective of this study is to analyze the commercialization of Combretum micranthum in Senegal. The study was carried out in two main regions of kinkeliba marketing in Senegal: Dakar, where kinkeliba is marketed; and Thies, where kinkeliba is produced and marketed. Structured and unstructured surveys were administered to different categories of stakeholders: herbalists / traditional practitioners, collectors/ suppliers, retailers and consumers. Production sites that supply Dakar include the following: Diass, Sindia, Kiniabour, Pout, Thies Lalane. The main sales points in Dakar are the Thiaroye and Grand Yoff markets. The kinkeliba marketing chain has short channels and women are the main stakeholders. Procurement is done by harvesting in the natural environment and by purchase for herbalists / traditional practitioners. The benefits and added value derived from the marketing of kinkeliba are positive and are increasingly evolving from producers to retailers. The kinkeliba chain, with its constraints and especially its strengths, requires better structuring and to be better known. Keywords: Combretum micranthum, kinkeliba, commercialization, value chain, Senegal.

Rabies is still a public health problem in Senegal. This study aimed to assess the knowledge, attitudes and practices on rabies among human and animal health professionals. It was a cross-sectional, descriptive and analytical study conducted in the Kaffrine district. Data were collected from 28 June to 01 July 2021. An exhaustive recruitment was done, and the final sample size was 95 health professionals. R software was used for descriptive, bivariate and multivariate analyses. Health professionals with sufficient knowledge, positive attitudes and good practices in relation to rabies represented 35.8%, 26.3% and 45.3% of the study respectively. The results of the multivariate analysis showed that professionals who worked in urban areas (AOR = 11.10, 95% CI = [3.50–41.69]) and who worked in animal health (AOR = 7.45, 95% CI = [1.16–70.40]) were more likely to have sufficient knowledge about rabies. Professionals with tertiary education (AOR = 12.40, CI95% = [1.80–268.00]) and with sufficient knowledge (AOR = 3.41, CI95% = [1.01–12.70]) were more likely to have a positive attitude about rabies. Professionals with a positive attitude about rabies (AOR = 3.23, 95% CI = [1.08–10.70]) were more likely to have a good practice when presented with an animal bite case. These results suggest that improving health professionals’ knowledge about rabies is essential in order to influence their attitudes and practices against rabies.

Due to the presence of tree species of high socio-economic importance, many protected areas in the sudanian zone are facing anthropogenic pressure that threatens their stability and resources integrity. This study aimed at providing a better understanding of woody plant composition and structure in Patako Forest in Senegal. Data collection was conducted by stratified random sampling in a total of 251 plots in different vegetation types. The results indicated that Combretum glutinosum, Terminalia macroptera, Cordyla pinnata, Elaeis guineensis, Acacia macrostachya and Khaya senegalensis were the most representative species. The Importance Value Indices (IVI) of these species varied significantly among vegetation types. Species diversity and structural characteristics were higher in gallery forest. The most important Shannon diversity indices was recorded in gallery forest (2.81) while it was medium in both woodland (2.12), tree savanna (1.55) and shrub savanna (1.24). Tree density was dominated by multi-stemmed species. Stem density was significantly higher in gallery forest (536 ± 13 per ha) and woodland (526 ± 12 per ha) than in tree savanna (364 ± 15 per ha) and shrub savanna (309 ± 14 per ha). Forest management should focus on gallery forest to enhance biodiversity conservation and increase the potential of carbon sequestration.

Wild fruit species provide local people with subsistence products and cash income. In addition to their food value, different used organs can, eventually, compromise the availability of these resources. This study aims to identify edible woody species in Kasa Zone and to analyze their socioeconomic importance. An ethnobotanical survey was conducted with 82 informants. Data collected were analyzed using Epi Info software and uses of species were classified into six categories. A Factorial Correspondence Analysis (FCA) highlighted species-organ relationships. Frequency of citations, fidelity index, selling price were used to show the socio-economic importance of the species. Results identified 62 edible species belonging to 31 families and 54 genera. These species were dominated by Annonaceae, Apocynaceae and generic diversity was more pronounced among Anacardiaceae. Identified species were mainly used for food (53%), energy (16%), technology (12%) and medicinal purposes (12%). The FCA showed three organ-use groups with a strong correlation between fruit and root on the one hand and leaf, bark and wood on the other. The study also identified 16 commercialized species. The fruit was the main organ consumed and marketed. The highest number of organs commercialized were recorded for Elaeis guineensis (4 organs) and Borassus aethiopium (3). These products, often collected and sold by women and children, came from villages and transited to markets through the "bana bana". Their prices depended on the locality isolation and the production period. These results open up perspectives for better management of the supply and commercialization of these forest resources.

Les espèces végétales autochtones permettent d’illustrer la diversité de services écosystémiques fournis par les milieux naturels. Cette étude a pour objectif de caractériser les services écosystémiques de Cordyla pinnata, une espèce autochtone typique de la zone soudanienne sénégalaise. Pour atteindre cet objectif, 97 questionnaires ont été administrés à des chefs de ménage dans la périphérie de la Forêt classée de Patako et les données ont été analysées avec des indicateurs ethnobotaniques. L’étude montre que Cordyla pinnata fournit 20 services écosystémiques appartenant à trois catégories, notamment les services d’approvisionnement, les services de régulation et les services culturels. La Valeur d’usage totale (VUt) de l’espèce est de 7,9 et les VU diffèrent en fonction des sites. Son Facteur de Consensus Informateur (FCI) est supérieur à 0,9 dans les trois catégories et ses Niveaux de Fidélité (NF) sont élevés pour la nourriture, la médecine traditionnelle, le bois, l’ombrage, la fertilisation des terres et l’héritage. Ces résultats permettent de dire que Cordyla pinnata a une grande importance dans plusieurs aspects de la vie des populations locales. Sa VU est plus élevée dans les localités éloignées de la Forêt classée de Patako où la couverture végétale naturelle est plus pauvre. Mais la majorité des services écosystémiques que l’espèce fournit sont perçus et appréciés localement, et sont compromis par la dégradation de son peuplement dans la zone. Ainsi, il conviendrait de mieux conscientiser les populations locales sur l’importance socio-économique et écologique de l’espèce afin qu’elles la préservent davantage et la restaurent dans les agro-systèmes., Local plant species allow illustrate the diversity of ecosystem services provided by natural ecosystems. The present study has the objective to characterize ecosystem services provided by Cordyla pinnata, an indigenous species of the sudanian zone of Senegal. To achieve this objective, 97 questionnaires were conducted with the head of households around Patako Classified Forest and data analysis was based on ethnobotanical indicators. This study shows that Cordyla pinnata provides 20 ecosystem services which belong to three categories : provisioning services, regulation services and cultural services. The total Use Value (UVt) of the species is 7.9 and UV differ among sites. Factor of Informant Consensus (FIC) is greater than 0.9 in all three categories and Fidelity Levels (FL) are high for food, traditional medicine, wood, shade, soil fertilization and inheritance. Results show that Cordyla pinnata is a useful species in many aspects of local people’s lives. Its UV is higher in sites distant from Patako Classified Forest were the natural vegetation is less abundant. However the majority of these ecosystem services provided by the species are locally perceived and enjoyed and is compromised by the degradation of its stand population in the area. Thus, it appropriate to make local population more conscious about the socio-economic and ecological importance of the species for them so that they the preserve it better and restore it in agro-systems.
