First, is the contribution to the development of the health activists role in public health services. Learning from the literacy campaigns there were many efforts at developing a community health approach of this the most important was the DST project (1997-99): “Building an effective, sustainable health activists source using appropriate S&T inputs and programme design.”  This was to lead later to two UNICEF programmes based on health activists ( 1999- 2004) , and still later it formed the technical basis or pilot on which the Mitanin programme of Chhattisgarh (2002 to present) was based, and this in turn led into the National Health Mission.

Another major contribution was the PSF role in initiating the peoples health movement in India. PSF provided  the seed funding and support to organize the visits of Dr Sundararaman to visit the different states and organize the first workshops that led to the massive mobilization leading to the first National Health Assembly in December 2000. This was the starting point for the People’s Health Movement (மக்கள் நல்வாழ்வு இயக்கம்), which has remained active ever since.

PSF has also undertaken community based work in rural sanitation, in reduction of indoor pollution and in nutrition. More recently it led a major study on the covid pandemic which was used to inform and improve policy response and government strategy.
