This group has experience in landscape ecology, particularly the description and characterization of landscapes based on their compounds and configuration attributes, as well as relationships between landscape structure and species richness. This large scale approach, not common in organic farming research, is useful in agroecology. Data collection to address these questions often involves large areas, which are more efficiently covered by remote sensing or digitalized aerial photography technologies. Recently developed computer techniques allow large data banks to be stored and analysed within a geographic information system (GIS) which is suitable for statistical analysis.

Two fieldwork studies on the agro-forest metropolitan mosaics of the Vallés plain (Barcelona, Spain) carried out at two different spatial scales are emphasized: 

1. Regional scale: relationship between landscape structure and birth species richness and conservation.

2. Spot escale: relationships between woodland spot size and plant species richness. The relationships between habitat fragmentation and human frequentation are also analysed.
