Biodiversity is crucial for the functioning of ecosystems on and next to the farm. In recent years, we have seen dramatic biodiversity losses for various reasons, including climate change, land use and increasing chemical use in agriculture. Organic farming practices are said to support and even increase biodiversity, but the results of these practices have been controversial. A new study published in the journal Organic Agriculture combined data from 98 studies and found that organic farming does indeed increase the diversity and frequency of plants, insects and birds, and is an effective strategy to combat biodiversity loss . The study used 474 comparisons of biodiversity and biodiversity in conventional and organic farms. The total biodiversity or frequency, including all plants, insects and animals, was higher in 58% of these comparisons in organic holdings. Plants showed the greatest benefit from organic farming, with 95% of the frequency comparisons being higher for organic arable land (arable land) and 21% for field margins. The frequency and variety of insects were also higher in 36% and 22% of the comparisons for organic animals. Finally, the frequency and diversity of birds in organic farms were higher at 24% and 35%, respectively. The authors emphasized that although they could use many studies for comparison, the method used for measurements was very different. Future research could benefit from whole farm measurements instead of just sampling one crop or field. This is particularly important for agricultural holdings and holdings with a lot of non-vegetation, which benefit biodiversity and are characteristic of many organic holdings
