Recent studies show that organic farming usually increases diversity, but that the effect varies among organism groups and with landscape context. In mosaic landscapes the effects on diversity are small, while it has larger effects in intensively farmed landscapes. However, one crucial factor - the time since transition from conventional to organic farming - has not been controlled in earlier studies. It is likely that, depending on the traits and dispersal ability of different organisms and on the landscape context, it may take a decade or even longer for effects of changes in farming systems to be fully manifested. A reliable assessment of the long-term effects of farming systems like organic farming on biodiversity and ecosystem services thus requires knowledge of both the speed and magnitude of changes in diversity and species composition in different landscapes.
 
The effect of landscape context on organisms very much depend on the organisms ability to move and disperse. This could also have affects on the possibilities for species to survive and reproduce and therefore the diversity we have in the landscape. It will also affect the ecosystem services in the landscape as they are performed by species interacting with each other and the environment.
