By extrapolating from the PLEC global experience, Pinedo-Vasquez, Gyasi, and
Coffey (2002) have developed the prototype of a more or less universal model of
the PLEC demonstration approach towards conservation and development. As
captured by Figure 5.1, the approach proceeds according to the following sequence:
formation of a team composed of a mix of relevant specialists, most notably
scientists, technicians, and farmers
farmer-based site assessment that is informed by existing conservation and
development initiatives
inventorying and documentation of conditions relevant to agriculture and bio-
diversity
