Contemporary studies surrounding the creation of civil society in Africa have revealed two important findings. First, despite the effort of civil society organizations in supporting inclusive democratic governance, promoting participation, advocating for transparency and accountability, sustainable development and stability remain elusive due to the challenges of social exclusion. Second, institutions central to the exercise of governmental powers exhibit inefficiency, weakness, lack transparency, and low credibility which worsen extreme poverty, inequality, and deprivation. Drawing upon extensive contemporary literature on social exclusion and inclusive growth, this study examines the role of civil society organisations as a pathway for social inclusion and sustainable development. Findings reveal that the management and distribution of services in the Nigerian society is largely inefficient and exclusionary, leading to myriad of social problems. This study has a significant implication for cumulative research on the subject of inclusive society and sustainable development.
