| Abstract | Afin de combiner efficacement conservation, utilisation durable des ressources et production du savoir, la réserve de biosphère doit nécessairement bénéficier d’une stratification, d’un zonage intégré et d’une gestion coopérative. La méthode de zonage est basée sur une caractérisation des ressources végétales, suivie de la spatialisation des enjeux et du zonage de la réserve de biosphère. Pour être partagé avec les populations locales, le zonage de la réserve de biosphère du Ferlo (RBF) a procédé par des réunions d’information et de sensibilisation, des observations sur le terrain, des enquêtes et une collecte de données biophysiques. L’étude des paramètres structuraux de la végétation a révélé que l’aire centrale de la RBF présente une densité d’arbres et un potentiel de régénération plus élevés. L’analyse du spectre d’abondance a montré que Guiera senegalensis J.F. Gmel est l’espèce la plus abondante dans la réserve. L’indice de diversité a révélé que la zone tampon et l’aire de transition qui font l’objet de multiples usages et qui subissent l’action de l’homme, présentent une diversité plus grande et un niveau d’organisation du peuplement ligneux plus élevé que l’aire centrale qui est une zone de conservation intégrale. Le traitement des images satellitales et la photointerprétation ont permis d’élaborer une carte d’occupation des sols et une carte globale du zonage. Ce zonage participatif a établi une spatialisation des fonctions de la réserve de biosphère sans pour autant les superposer.Mots clés: Réserve de biosphère, carte d’occupation, zonage, conservation, biodiversité, utilisation du râble. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
