Systems Assessment of Beef Sustainability

Autor: Jason E. Sawyer

Publikováno v: The Veterinary clinics of North America. Food animal practice. 38(2)

Assessment of sustainability of a system is largely a forecasting problem, in which the likelihood of system persistence must be evaluated. The use of systems thinking and systems analysis provides useful mechanisms for assessing sustainability in co
