Non-Governmental Organizations (NGOs) and Faith-Based Organizations (FBOs) have made significant contributions to social development, poverty reduction, health care, education, humanitarian relief, and community empowerment across Africa. However, despite their positive role, these organizations face several weaknesses that limit their effectiveness and sustainability. Understanding these challenges is important for improving social work practice and strengthening community development. One of the major weaknesses is dependence on external funding. Many NGOs and FBOs rely heavily on financial support from international donors, foreign governments, and charitable foundations. This dependence often results in financial instability when donor priorities change or funding is reduced. As a result, valuable social programmes may be discontinued, leaving vulnerable communities without essential services. Another weakness is the lack of sustainability. Many projects are implemented for a limited period based on donor funding cycles. Once funding ends, projects often collapse because local communities lack the resources or capacity to continue them. This undermines long-term development and creates dependency rather than self-reliance. Poor coordination among organizations is another challenge. In many African countries, several NGOs and FBOs work in the same geographical area without proper collaboration. This may lead to duplication of services, inefficient use of resources, and neglect of other communities that remain underserved. Weak coordination with government institutions also
