We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs—such as maintenance of soil quality, nitrogen fixation, pollination, and pest control—to agriculture. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agricul...
The sustainability of breeding activities in 15 pig farming systems in five European countries was evaluated. One conventional and two differentiated systems per country were studied. The Conventional systems were the standard systems in their countries. The differentiated systems were of three categories: Adapted Conventional with focus on animal welfare, meat quality or environment (five syst...

This paper focuses on the role of scavenging poultry in integrated farming systems and is mainly based on previous studies and past research and development attempts to improve scavenging poultry in Ethiopia. Village poultry production is an integral part of a balanced farming system and has a unique position in the rural household economy, supplying high quality protein to the family. In this ...
Sustainability is de®ned as the ability of a system to `continue'. In view of this de®nition, several aspects of the crop protection activity in organic farming are reviewed according to their ability to `continue'. As no absolute measure of sustainability is available, this analysis takes the form of a comparison between organic and conventional crop protection methods. Two elements of crop pr...
