Abstract

This study allowed determining diverse roles of the mangrove in Delta du Saloum. To the ecological plan, the slightest environmental changes are harmful to mangrove (Ndour, 2005 ; Thomas and al., 1997 ; Blasco, 1983). The consequences are their degradation and the loss of the functions of nurseries, housing environment and niche ecological. In the socioeconomic aspects, mangrove exploitation resources make them playing the role of rampart of the livelihood of the coastal populations (Sène, 2007 ; Cormier-Salem, 1999). So, the goods and services which the mangrove procures to population, gets created divergent interests between the various actors ; what makes difficult their management. Among others obstacles, there is their sector-based management which implies at once several state services. This sector-based approach not facilitates harmonization of the measures of preservation. Otherwise, in spite of the existence of several plans of management, there is always no transfer of competence in fishery domain which prevents in a part the actors to play entirely their roles. In these conditions, perspectives of mangroves management should turn around the harmonization of the measures of protection, decision-making by the Ministry of fishery on marine resources, the elaboration of landscaping of classified forests and codes for good behavior in the area. This need also to promote joint management including the neighboring States sharing the same resources (Ndour, 2005).

Abstract

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.

Abstract

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.
