This work traces the role of social capital and strategies for strengthening it in order to ensure effective and efficient management of natural and man-made disaster risks. To collect the data, questionnaire surveys of 383 households, focus group interviews, and research meetings were conducted. Several techniques, including content analysis, analysis of variance, etc., allowed us to assign meanings to the field data. The results of the research demonstrated that social capital plays a major role in the development of collective actions and a common vision of natural and man-made disaster risk management in the Buzi and Mbinga-Nord groups.
