| Abstract | Les plages de Jerba (sud-est de la Tunisie), situées sur les côtes nord-est et sud-est de l'île, sont en cours d'érosion rapide, sauf dans leur partie distale où s'accumule, sous la forme d'une flèche, le sable qui leur est enlevé. Cette érosion est d'origine naturelle : la réserve sous-marine en sédiments est épuisée, les apports en matériaux d'origine terrigène sont inexistants et le niveau relatif de la mer s'élève par suite de la subsidence de l'île. Elle a été aggravée par des actions humaines depuis une quarantaine d'années en relation avec le développement du tourisme balnéaire. D'importantes extractions de sable ont été opérées sur les plages. Les hôtels, construits au plus près du rivage et vite menacés par le recul de la côte, ont dû être protégés par des ouvrages de défense qui ont eu pour effet d'accélérer l'érosion. |

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.
