This research investigates the detrimental impact of bad governance, characterized by corruption, nepotism, and lawlessness, on achieving the UN's Sustainable Development Goals (SDGs). It argues that bad governance diverts resources, weakens institutions, and hinders progress on critical areas like poverty reduction, environmental protection, and social justice. The study employs a multi-faceted approach, analyzing the specific ways bad governance hinders SDGs, exploring successful case studies, and identifying key factors that contribute to good governance. The research findings hold significant value for policymakers, civil society organizations (CSOs), and international development agencies. By understanding these challenges, stakeholders can design targeted interventions, advocate for good governance reforms, and foster a more sustainable future. Ultimately, the study concludes that overcoming bad governance requires a collective effort and a commitment to transparency, accountability, and public participation. This paves the way for achieving the SDGs and creating a more just and sustainable world.
