Sombath worked closely with Quaker Service Laos (QSL) during the late 1980s and early 1990s. He made significant contributions to their programs, including the Rice Integrated Farming Systems (RIFS) project.
A “History of Quaker Service Laos Development Work 1973-1999″ mentions the RIFS project, and how it evolved into The independent Participator Development Training Center (PADETC) .
While QSL staff wrote a plea to the Lao government soon after Sombath’s abduction, subsequent requests to contribute their thoughts about Sombath and his work have been unanswered.
Those who worked with Sombath are encouraged to share their experiences by writing a Letter to Sombath.
