Finding the location of the mines with no witness or map record is a very difficult task that needs very specific tools, and demands a lot of time, and trained staff, and therefore also a lot of investment. Currently, most of the remaining mines are frequently found in the fields. Nowadays identifying the areas with mines and clearing them is carried out in the North West of the country, where most of the remaining mines are found. APOPO, a Belgian non-governmental organization which uses rats to detect landmines also joined the demining efforts in 2014.
