Sometimes farmers carry out selection or choice intentionally to change or conserve VG. However, much of farmer practice is intended to further production and consumption goals and affects crop evolution unintentionally. Therefore, in order to understand farmer selection and conservation, it is important to understand the relationship between production, consumption, selection and conservation in TBAS, and between farmer knowledge and practice and the basic genetics of crop populations and their interactions with growing environments.
and conservation in TBAS contrast substantially with industrial agricultural
systems, and understanding farmers' practices, and the knowledge and goals
underlying them, is critical for supporting food production, food consumption,
crop improvement, and crop genetic resources conservation for farm communities
in TBAS and for long-term global food security. The urgency of understanding
farmer selection and conservation will increase in the future with the
on-going loss of genetic resources, the rapid spread of transgenic crop
varieties with limited genetic diversity, the development of a global
system of intellectual property rights in crop genetic resources, and
the movement to make formal plant breeding more relevant to farmers in
TBAS through plant breeding and conservation based on direct farmer and
