Natural farming or flower strips – which is best for bees? – BIOENGINEER.ORG


How efficient environmental measures in agriculture are for biodiversity and wild bee populations depends upon numerous elements and your perspective. That is proven by agroecologists from the College of Göttingen, Germany and the Centre for Ecological Analysis in Vácrátót, Hungary. The analysis crew discovered that when assessing the effectiveness of various measures, whether or not within the area (natural farming) or subsequent to the sphere (flower strips in standard farming), biodiversity advantages ought to be evaluated in a different way. Like-for-like comparisons of environmental measures may simply be deceptive, in line with the scientists. The analysis was printed within the journal Primary and Utilized Ecology.

How efficient environmental measures in agriculture are for biodiversity and wild bee populations depends upon numerous elements and your perspective.

Like-for-like comparisons of environmental measures may simply be deceptive, in line with the scientists. The analysis was printed within the journal Primary and Utilized Ecology.

 

The researchers studied ten agricultural landscapes close to Göttingen, every containing three winter wheat fields: one natural area, one standard area with flower strips, and one standard area with out flower strips. For 2 years, the abundance of untamed bees was recorded on the edges of every of those thirty fields. The outcomes confirmed {that a} easy comparability of the info sampled at particular websites may result in the conclusion that standard fields with strips of flowers may entice many extra bees than natural fields however this isn’t the complete story.

 

“After we regarded extra intently, this didn’t give us an entire image as a result of it didn’t consider that flower strips solely cowl about 5 % of standard fields which has considerably fewer bees general than the natural farmland,” explains Professor Teja Tscharntke, Division of Agroecology at Göttingen College. Dr Péter Batáry, group chief on the Centre for Natural Analysis in Vácrátót, Hungary goes onto say: “In brief, natural farming, which generally has extra wild vegetation than standard fields, is definitely extra profitable than standard fields with flower strips in selling bees.”

 

The lacking piece of the jigsaw is the truth that fields of grain in natural farming yield solely half the harvest of standard farming. When the loss in wheat yield is taken under consideration, a ten-hectare space of natural farmland ought to be in comparison with 5 hectares of standard farmland plus 5 hectares of flower strips, which might result in 3.5 instances extra bees however the identical yield. On this state of affairs, natural farming wouldn’t be one of the best ways to assist wild bees.

 

“These information and concerns present that totally different benchmarks and standards ought to be taken under consideration when evaluating agri-environmental measures. It’s only once we consider the world together with the yield along with the kind of farming that we will obtain a balanced understanding of the ecological and financial effectiveness of environmental measures,” the authors say.
