Celestial Knowledge as Lived STEM: African Women’s Ethno astronomy, Social Roles, and Anticipatory Practices
Main Article Content
Abstract
Ethno‑astronomy has often been treated as either cultural cosmology or proto‑science, yet fieldwork across African societies reveals a more integrated reality, particularly for women. This review moves beyond descriptive accounts of celestial observation to argue that African women’s ethno‑astronomy constitutes a form of lived STEM: a knowledge system that is empirically grounded, technologically expressive, and socially anticipatory. Drawing on ethnographic cases from Eastern, Southern, Western, and Central Africa—including Borana lunar‑stellar calendars, Batswana moon‑based reproductive pedagogy, Chopi and Muyanga body‑star symbolism, Igbo lunar‑menstrual tracking, and contemporary girls’ satellite programs in Ghana—this paper demonstrates how women use celestial cycles to anticipate agricultural seasons, reproductive health events, and community responsibilities. These practices are not merely cultural add‑ons but active, methodical engagements with mathematics (cycle tracking, ethnomathematics), astronomy (heliacal risings, alignments), engineering (body technologies, built alignments), and even modern space science. The paper further argues that recognising women’s sky knowledge as STEM has practical implications: it validates indigenous epistemologies, provides culturally responsive pathways for female STEM participation, and challenges the marginalisation of African expertise in global science education. By centring African women’s roles as knowledge keepers and anticipatory agents, this review calls for a decolonised, gender‑inclusive framework for ethno‑astronomy one that treats celestial knowledge as a living, actionable STEM practice.
