The Centre for Technology & Development, or CTD is a Unit of the Society for Economic & Social Studies (SESS), is an independent non-profit organization working in the field of sustainable Rural Development through Science & Technology Applications.
The formation of CTD with several Field Stations in Dehradun (UA), Mandi (HP), Ukhrul (MANIPUR) and Kavali (AP) was catalysed by the Delhi Science Forum, a reputed public-interest organisation focusing on S&T policy issues, with the goal of putting forward and demonstrating alternative models for sustainable development. The Field Station at Sahaspur, Dehradun, UA continues to operate under CTD aegis while other Field Stations have been spun-off into independent registered Societies.
