Iran’s agriculture is facing serious environmental pollution
and degradation problems (Karami and Mansoorabadi,
2008) and extension has a key role to improve it
(Ahmadvand and Karami, 2007; Allahyari, 2008), but current
extension system in Iran does not have a sufficient
competency for the achievement of sustainability and it
needs to shift toward new approaches and models. It is
concluded that agricultural extension systems toward
accomplishment of sustainability should be departed from
reductionism thoughts (Allahyari and Chizari, 2008), and
they must focus on holistic and systematic perspectives.
Being success and being dynamic the system-based
extension models depends on identifying the environment
and the context of systems and the interactions occur
among them. Finally, re-thinking in agricultural extension
components is mandatory and we must strive to find new
functions, strategies and objectives for extension systems
toward sustainability.
