Agriculture is mainly seen as a threat for biodiversity of agroecosystems. Intensification of agriculture and its expansion into marginal lands has substantially modified the physiognomy of rural landscapes through fragmentation and homogenization, promoting the loss of both natural habitats and biodiversity (Benton et al., 2003). Nevertheless, agricultural landscapes harbor an important range of biodiversity, both within crops and in non-crop habitat (Storkey et al., 2012).
This kind of contrasting arguments have been long associated to debate on increasing contribution of agriculture on supplying global food demand and environmental cost of intensifying agricultural production system.
