Mapping is seen to be advancing over the years with the introduction of spatial science and technology in developing countries which was rarely in use. This advancement should now help with the solving lot of local problems associated land in the Developing Africa. As i have said, ‘local problems’ .The frontiers for solving these problems should be the African youth. As an African,A mapper,member of IRDPyouth mappers, an Enviroment planner, i urge all my fellow youth to be not only members of OSM, but to do it with passionate to their Mamaland.
