Welcome to Dharani USA, Inc. (DUSA), a 501(c)(3) organization set up in the USA as a sister organization to The Institute of Geographical Studies (TIGS), Bangalore, India.

“Dharani” is a Sanskrit word meaning “Earth.”

Since 2000, when DUSA was set up, we have been instrumental in raising funding and other resources for the work that TIGS is doing in India to promote non-formal geography education there. Among the activities of TIGS are:

Interactive geography workshops for K-12 children and teachers through two GeoVidyaa Geography Centers (in Bangalore and Chennai).

Field-trips for K-12 children and teachers.Online non-formal geography lessons for home-schooling and school children.

International Geography Youth Summits (IGYS) — this is an annual event, the flagship event that brings together children, teachers, parents, older students, and anyone interested in geography together in one place for great interactions.

Mr Muniraju, Dr Shashi Rekha Muniraju, Dr Heidi Nast, and Dr Sue Roberts look on as students of Vidyanjali Academy for Learning, light the inaugural lamp at IGYS 2018.

I am a Bengaluru native. I earned my PhD in Geography at Kent State University, Ohio. After teaching in the US for about 20 years, I returned to India in 2000 and I started TIGS to help deliver more relevant and engaging geography education.

Through TIGS, I have worked to offer non-formal geography education in different formats primarily for school children, and for anyone else interested. (Here is my CV)
