Penchom Saetang is a leading figure in the environmental protection and justice movement in Thailand. She is the Executive Director of Ecological Alert and Recovery Thailand (EARTH), which is a member of IPEN since 1998. She started working on a citizen-centered approach in 2004 in identifying the air pollutants released from the petrochemical industrial complex in the Map Ta Phut area, Rayong Province, which is the largest industrial pollution hotspot of the country. In 2006, Penchom received the prestigious Asian Public Intellectual Fellowship, funded by the Nippon Foundation, and was elected to the Ashoka Fellowship in 2010. In 2015, EARTH established a citizen science project to protect the environment and public health by gathering data on the chemical contamination in the environment caused by industries, strengthening the negotiation power of people, and helping affected communities exact accountability from the polluters and government to ensure their safety and that of the general public.
