PROJECT AREA ZONE 1 B U R K I N A F A S O The process starts with District Assembly Consultations. The consultations involve the use of existing District Feeder Roads Maps as reference for sketching in, all the missing roads that are not on the map with the participation of all stakeholders in a mass-mapping exercise REPUBLIC OF COTE I'VOIRE REPUBLIC OF TOGO The output from the consultation is an up-to-date sketch map of all the engineered and unengineered roads in the district.
