Various indicators suggest that poverty is a major obstacle to Nigeria's socio-economic development. Poverty has persisted and several interventions have failed to yield significant improvement in Nigeria's Human Development Index even in periods of economic growth. Plagued with the challenges of unemployment crises, climate change, conflict, fragility and violence, Nigeria (the most populous country in Africa) stands at a grave risk if poverty is not tackled. This paper explores seven theories of poverty in literature: The Culture of Poverty, Individual Deficiency Theory, Progressive Social Theory, Geographical Disparities Theory, Cyclical Interdependence Theory, Poverty Individualisation and the Theory of Social Exclusion /Cumulative Disadvantage. It reviews these theories by employing a qualitative and descriptive research approach in order to broaden the understanding of the complexities of the phenomenon of poverty from a global worldview and examine how these relate to the nature of poverty in Nigeria. It corroborates the fact that poverty in Nigeria is complex and multidimensional in its conceptualization and measurement, encompassing economic, social, cultural and psychological indicators. The paper therefore attempts to explore the phenomenon of poverty within the Nigerian context by examining these theoretical paradigms. It suggests an understanding of underlying causal factors of poverty in designing pro-poor programmes and a hydra-headed approach to tackle its menace effectively and progressively. It argues that poverty reduction is realizable by empowering people to develop resilience to cope and overcome it within the scope of their resources and capabilities.
