Yetunde Odeyemi is a geography graduate with doctoral research studies in human dimensions to Climate Change and its impact on different aspects of human security. She has observed with keen interest the phases of changes in the subject of geography and how it has revolutionized databases through geo-technologies, in maps, mapping, map use and reading, cartography, remote sensing, and virtually all other fields of studies and learning. This is showcased in today’s use of GIS/ArcGIS in virtually every aspect of human studies and career that requires visualization, and information gathering and sharing at real-time levels. Yetunde strongly believes that the study of geography as a subject broadens the human mind and enables a scholar to fit into many aspects of studies and careers.
Apart from geography, she has specialization in gender studies, Monitoring and Evaluation, and in the use of ArcGIS as a tool in spatialization of the humanitarian and development stories. After teaching at the high school level, Yetunde transitioned into the sphere of research at a University Center for Gender and Social Policy Studies. She then moved into lecturing and mentoring of students at different levels of Tertiary Institutions (Church-owned and government-owned).
Yetunde was baptized into the Adventist faith in 1988 after her husband and brother joined the church that same year. With her family called to serve in the church’s mission field, she has worked in different capacities in church departments and boards. She enjoyed her days as a humanitarian and development worker and facilitator of capacity-building sessions.
Yetunde is grateful for the ability to hear, listen, and enjoy testimonies of Jesus’ “unshortened hand and active responses” of intervention in the issues of humanity. She has an eye for details in sight and sounds. She is passionate about education and educating (especially through Bible study, Sabbath School, and Prophecies Seminars), treating people with respect, with avid interest for compassion and kindness. She likes helping because it is a God-given principle to mankind and a philosophy that God never ignores the open hand. He desires to have it filled.
Yetunde likes to bake, sew, and crochet (for the elderly and children in prison), collect colored stones, and record the sound of flowing water bodies. She also seeks to understand historic levels of communication in African societies, African hair, and skincare. She loves reading and gathering information to compare information from different sources in order to have a robust view.
