In the 1980’s DCT combined evangelism with development but in the 1990’s, DCT separated evangelism from development. Department for development services therefore became an autonomous department.
Between 1990 and 2005, DCT through its department for development services used an integrated approach to community development through various ADPs (Area Development Programs) across the diocese. Such ADPs were; Itiso ADP, Chilonwa ADP, Hombolo ADP, Mwitikira ADP, Chipanga ADP, Lamaiti ADP, Chemba ADP, Mvumi ADP and Ibihwa ADP. Activities under each ADP were; agriculture, livestock, environment, relief, nutrition, education, health and community water supply.
