Abstract
Contemporary environmental discourse has been concerned with persistent challenges, including biodiversity loss, climate change, deforestation, and ecosystem degradation that undermine planetary sustainability. This paper examines how environmental conservation can achieve legitimacy and effectiveness by grounding itself in indigenous cosmological systems, specifically the Igbo of southeastern Nigeria eco-spiritual worldview. Employing philosophical hermeneutics and analysis as methodological approaches, the study argues that sustainable environmental stewardship emerges when communities engage with nature through spiritual principles rather than purely utilitarian arrangements. The paper demonstrates that Igbo cosmology, embodying concepts of vital force, ancestral continuity, cosmic balance, and sacred ecology through deities such as Ala, Amadioha, Anyanwu, and Mmuo Mmiri, provides the moral foundation necessary for authentic environmental care. The relationship between eco-spirituality and conservation establishes spiritual accountability mechanisms that transcend purely technical solutions, ensures that environmental practices reflect communal moral principles, and creates collective responsibility grounded in spiritual conviction. The paper concludes that integrating Igbo cosmological principles into contemporary conservation efforts through sacred groves, totemic protections, ritual practices, and traditional ecological knowledge offers Africa and the global community a paradigmatic pathway toward legitimate, accountable, and effective environmental governance that synthesises universal conservation principles with particular African spiritual realities.
