The study is based on the analysis of the results of interviews of strategic leaders directly or tangentially responsible for the strategy and planning of social security (Odesa City Council, territorial united communities in Odesa, Mykolaiv, and Kherson regions). During the research, the project team reached two important conclusions regarding: a) the need to change the methodology of this kind of research in the direction of "mixing" methods of research on socio-economic changes. This is appropriate because expanding and combining or mixing methods of socio-economic change research improves understanding and definition of complex interactions in modern society and rapidly changing environment; b) the application of the charity marketing approach, its principles and tools by strategic leaders directly or indirectly responsible for the strategy and planning of social security, in the activities of relevant structures and organizations, in the development of post-conflict strategies and solutions to support the economic reintegration and resocialization of affected women and children.
