The Church made an impact in the life of Vijayam as those were the days' of early Christians in the Telugu hinterland where the Catholic[18] and the Protestant Missions had already set foot.
After initial studies in schools across Andhra Pradesh, wherever his father (Bunyan Joseph) was transferred, Vijayam moved to Madras Christian College, Tambaram for a pre-University course (PUC).
Towards this end, he drew talent from universities as a matter of service[22] and also sought the partnership of United Nations Development Programme,[23] Government of India,[24] and other[25] funding agencies.
Vijayam's NGO creations, including PROGRESS and TENT, integrate geological principles into almost every aspect of holistic rural development.
Water sources, sanitation, erosion, agriculture, land-use planning, and energy provision are all analyzed and managed as components of a larger, single geological system.
