[10] Vijayam's research articles began appearing in geological and other inter-disciplinary scientific journals for more than three decades and continue to be referred by the present generation[11] of Geologists.

During the Fifth National Convention of the Christian Businessmen's Committee in 1987[13] held in Hyderabad, he spoke on the theme You shall be witnesses unto me and shared dais with Archbishop Samineni Arulappa,[13] Member of parliament, Lok Sabha Marjorie Godfrey and Policeman G. Alfred,[13] IPS.

Vijayam also led honorary initiatives towards Christian missions by equipping[14] the Laity not only with knowledge of the Gospel, but also a means of livelihood was recognised by Theologians, comprising the Missiologist, Roger Hedlund,[15] SB, and Bishop Ezra Sargunam,[16] ECI.

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.

[23] By 1982,[30] Vijayam founded Peoples Research Organization for Grass-root Environmental Scientific Services[31] (PROGRESS)[32] as a platform to share the benefits of technological advancement[33] with the rural[34] poor.

In 1996,[37] P. Sita Janki and K. Sumalini contributed a paper entitled Enhancement of seed germination in Amla (Emblica officinalis Gaertn.)

[41] At the same time, Roger Hedlund had acknowledged Vijayam's efforts towards founding TENT in equipping individuals with means of livelihood as well as basic theological principles.
