A body farm is a research facility where decomposition can be studied in a variety of settings. The initial one was conceived by anthropologist William M. Bass in 1971 at the University of Tennessee in Knoxville, Tennessee, where Bass was interested in studying the decomposition of a human corpse from the time of death to the time of decay. The aim was to gain a better understanding of the decomposition process, permitting the development of techniques for extracting information such as the timing and circumstances of death from human remains. Body farm research is of particular interest in forensic anthropology and related disciplines, and has applications in the fields of law enforcement and forensic science. By placing the bodies outside to face the elements, researchers are able to get a better understanding of the decomposition process.
