Award ceremony at the Dies academicus
On the occasion of the 181st Dies academicus 2015 at the Kultur-Casino in Bern, the two winners of the Bernese Award for Environmental Research 2015/16 were honored for their work.
The Main Prize goes to Dr. Pierrick Buri for his scientific publication “Promoting Pollinating Insects in Intensive Agricultural Matrices: Field-Scale Experimental Manipulation of Hay-Meadow Mowing Regimes and Its Effects on Bees”. Extensively used meadows are among the most biologically diverse habitats in Switzerland and Europe. In recent decades they have come under strong pressure due to the continued intensification of farming practices. Various measures have been introduced in Switzerland and in Europe to counteract the negative effects of the intensification of agriculture – unfortunately, with limited effect on biodiversity. Pierrick Buri investigated how such measures, in particular the extensive farming of meadows, can be made more effective in terms of benefits for wild bees. He tested various mowing regimes and compared their effects on the diversity of wild bees. The greatest benefit for wild bees is provided by meadows which are left partly unmowed in the first round of mowing. Meadows used in this way provide the wild bees with vital resources at a time when these sources are largely lacking elsewhere. The results of Pierrick Buri’s work can be directly incorporated into agricultural policy and provide an important contribution towards optimizing the benefits of environmental measures in agriculture for biodiversity.
The Recognition Award goes to Bettina Scharrer for her master’s thesis on the problem of manure in Lake Sempach, and the interplay between intensive animal husbandry and water protection in canton Lucerne from 1976 to 2003 (title in German: Dem Sempachersee kommt die Gülle hoch – Das Spannungsfeld zwischen intensiver Tierhaltung und Gewässerschutz im Kanton Luzern 1976-2003.) In her thesis Bettina Scharrer investigates the problem of the “dying lakes” in Lucerne’s central plateau, a phenomenon that has been mainly caused by excessive phosphorus in the water. This eutrophication is the result of intensive livestock production, which has led to the overfertilization of fields. She also investigates possible approaches to countering this eutrophication, taking the examples of Lake Sempach, Lake Baldegg, and Lake Hallwil. Bettina Scharrer provides a differentiated insight into the variety of factors that have led to this environmental problem, and shows which social and agricultural developments, actors, interests, and policies were involved in creating it. The thesis is well-structured and contains a restrained, balanced assessment of an emotionally charged topic, thus contributing to a better understanding of a still current and partially unsolved environmental problem.
