More biodiversity on organic farms

Published: 04 December 2012

At a seminar on December 4 Camilla Winqvist presented results from a knowledge synthesis of research on biodiversity and ecosystem services. The synthesis will soon be published.

Camilla began by answering the question whether there is more biodiversity on organic farms with a big YES! Then she complicated the picture pretty well… For example, there are conventional farms that have more biodiversity than organic ones in the same study.

Biodiversity benefits from small-scale and varying landscapes, varied crop rotation, sparse crops and less weed and pest control. Mechanical control can be as negative as chemical control for wild plants and animals that live in the fields.

Plants that are pollinated by insects, annuals and more unusual species are the ones that benefit most from organic farming.
