Interesting article from the UK looking into land-use intensity and the effects on biodiversity from organic farming vs conventional farming.  

This article from the United Kingdom discusses land-use intensity and the effect organic farming has on biodiversity compared to conventional farming practices.

Key points were as follows:

  • There is no question that organic farming is more beneficial for biodiversity than conventional farming methods so the benefits should be weighed up between the two before deciding which method is best for your enterprise.
  • This article focuses on a hierarchical meta-analysis of various studies to calculate the effects on biodiversity with both organic farming and conventional farming practices to discover if any organic farming patterns exist.
  • Organic farming showed that species were 30% higher compared to conventional farming.
  • There is poor availability to studies on organic farming however the studies here covered two main areas, they were: 1) Western Europe 2) North America.
  • The analysis of these studies conclude that biodiversity is much better off when organic farming is chosen over conventional farming, however results vary across regions, crop varieties and soil types.
