Social work occupies a central position in addressing complex social, economic, and political challenges across diverse global contexts. Rapid globalization, technological advancement, demographic transitions, and rising social inequalities have reshaped both the scope and practice of social work worldwide. This paper examines the contemporary global landscape of social work by analyzing key structural and practice-based issues, including poverty, migration, mental health, child welfare, and social exclusion. It further explores innovative approaches such as digital social work, community-based participatory models, and interdisciplinary collaboration that are transforming professional practice. By synthesizing international literature and comparative perspectives, the study highlights emerging trends and identifies future pathways for strengthening social work education, policy engagement, and professional capacity. The paper argues that responsive, culturally informed, and ethically grounded social work practice is essential for promoting social justice and sustainable human development in an increasingly interconnected world.
