This study explores the dynamics of decentralized governance and local government management in the Zamboanga Peninsula region of the Philippines. It offers an analytical review of the policy frameworks, institutional structures, and challenges associated with decentralization in the region. Through a comprehensive examination of existing literature, interviews, surveys, and case studies, the research evaluates the extent to which decentralization has impacted local governance, service delivery, and citizen engagement. The study finds that while decentralization has the potential to enhance local autonomy and improve service delivery, its success is often impeded by institutional capacity gaps, political interference, and limited financial autonomy at the local government level. Moreover, the study highlights the importance of citizen participation and institutional reforms in maximizing the benefits of decentralization. The findings contribute valuable insights to the ongoing discourse on local governance and offer recommendations for strengthening governance structures, improving financial management, and enhancing citizen engagement to facilitate more effective decentralization in the Zamboanga Peninsula region.
