This study reviewed relevant bibliography and
then developed a simple conceptual model, in which soil functions
and ecosystem services were compared between conventional,
conservation, and integrated agricultural systems. The overall agro-environmental score was largest for conservation systems (71.9 %),
intermediate for integrated systems (68.8 %), and smallest for
conventional systems (52.1 %). But the crop yield
productivity score was largest for integrated systems (83.3 %),
intermediate for conventional systems (66.7 %), and smallest for
conservation systems (58.3 %). This study shows the potential of integrated farming systems in global
food security while sustaining environmental quality.
