Africa's escalating ecological crisis, marked by deforestation, erosion, biodiversity loss, pollution, and climate instability, has sparked increasing calls for environmental approaches grounded in indigenous knowledge. This study explores the Igbo concept of Ala, the Earth deity seen as an ecological mother, and its relevance to today's environmental sustainability debates in Africa. In Igbo cosmology, Ala is more than a spiritual figure; she is the moral guardian of land, fertility, social harmony, and ecological balance. Traditional reverence for Ala shaped human-nature relationships through taboos, rituals, sacred groves, moral sanctions, and communal ethics that discouraged environmental harm and promoted ecological stewardship. Using Indigenous Ecological Knowledge and African Environmental Ethics as frameworks, this qualitative and interdisciplinary study analyzes oral traditions, ethnographic records, religious practices, and scholarly literature on Igbo religion and ecology. It argues that modernization, urbanization, and religious shifts have eroded indigenous ecological values, weakening cultural systems that regulated environmental care and contributing to degradation. Recovering and reinterpreting Ala's ethical principles offers culturally rooted pathways for sustainable governance and biodiversity conservation in Africa. The study concludes that indigenous African religious philosophies provide valuable ecological insights that can complement modern environmental policies and global sustainability goals.
