Swipe slowly through the satellite imagery and mark anything that looks like it could be a house, village, hut, plants or plantation (buildings to reach people, vegetation to highlight economic potential, both to prioritize actions). In Northern Chad, more than 268 km of road are highly contaminated by mines, from years of Libyan occupation. On top of causing accidents, mines obstruct access to vital resources such as water, agricultural areas and then prevent local development. Mapping will help Handicap International and communities, institutions, local actors working together to revive local development in those areas weakened by decades of armed conflicts.
