With clear and accessible content, enriched with practical applications and experiential learning experiences, this manual effectively prepares Social Work students for their professional careers in community settings. Through theoretical tools, examples, and exercises, the skills necessary for effective intervention in community social structures are developed. The text focuses on the organization and mobilization of communities—whether they are geographical areas, identity-based communities, or thematic coalitions—with the aim of social change based on principles of cultural sensitivity, equality, and social justice. The revised edition includes expanded chapters covering contemporary and critical issues such as self-care for community professionals, the major "challenges" of Social Work, cultural humility, community dialogue, trauma-informed community development, environmental justice, and many more topics. The book presents various models of macro-Social Work application and is aimed at both undergraduate and postgraduate students, as well as professionals working in communities, focusing on utilizing specific skills in their professional practice—such as team development, partnership building, public participation, policy advocacy, and lobbying. The text also emphasizes the importance of technology as a tool for macro-Social Work, enhancing systematic cultivation and deepening in this area as well. Its structure is supported by real-life examples, case studies, experiential exercises, and additional educational resources for further exploration, contributing to the meaningful development of professional skills and engaging students in an active learning process aimed at skill development. For the Greek edition, illustrative examples from programs and communities in Greece and Europe have been incorporated to reinforce the relevance of the content with real data and the experiences of professionals in the Greek and broader European context.
