14/10/2014The A.B.C.D. approach (Approach focused on Behaviour Change Determinants) is an anthropology-based approach developed by SOLIDARITES INTERNATIONAL. It is used to develop WASH operational strategies aiming at an optimal and sustainable impact on the reduction of water-borne diseases. It involves studying WASH behaviours along with the socio-cultural and economic determinants of these behaviours. As an example, we present the results of a study carried out in June 2014 in a peri-urban neighbourhood of Kinshasa in the Democratic Republic of Congo to illustrate how the A.B.C.D. approach helped shape the operational strategy of a project.
