Abstract | Degradation of watersheds by the phenomenon of erosion has now a great danger for the development of rural areas in Madagascar since on the one hand, the risk of losing a considerable amount of arable soil into rivers is rising and this is irreversible, and on the other hand, the alluvial deposits continue to overrun the agricultural parcels already developed. This paper aims to introduce an assessment methodology with reliable accuracy of the extent of damage caused by water erosion in order to guide the actions of protection and watershed management. This methodology is based on geographic information technology management. Accurate orthophotographies and digital terrain models were established from aerial photography of the study area taken in two different dates. The orthophotography is used to evaluate the surface extent of the phenomena through digitization, the digital terrain model used to evaluate the movement of land through the volumetric calculation. This method has the advantage of being rich in information and can therefore generate other useful products such as the slope map, aspect map,... In conclusion, it is a great decision making tool for the politics as well as developers. |

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.
