Agroecological conversion of conventional production systems: theory, strategies and assessment

Abstract

Agroecological conversion of conventional production systems: theory, strategies and assessment.

The conversion of high input conventional monocultures to diversified, low external input agroecosystems is based on two agroecological pillars: habitat diversification and organic soil management. Te optimal function of agroecosystems depends on the spatial-temporal designs that promote synergies between above and below ground key biodiversity components, which in turn determine the expression of ecological processes such as pest regulation, nutrient cycling and productivity. The evolution of this agroecological transition can be monitored using sustainability indicators which assess soil quality and plant health.
