Plant species diversity in grasslands is known  to increase and stabilize biomass yields. We economically evaluate  these effects, using a rich dataset from 16 intensively managed  grassland sites across Europe. We extend earlier research by accounting  for plant species diversity effects on both quantity and quality of  yields. Consequently, we can express plant species diversity effects in  terms of milk production potential yields per hectare and potential  revenues thereof. Plant species diversity not only increased milk  production potential yields and thus revenues, but also reduced  production risks. Thus, increasing plant species diversity resulted in  higher certainty equivalents, for example, the certainty equivalent rose  by +29% when comparing the average mixture to the average monoculture.  For risk averse decision makers, this gain in certainty equivalent was  mainly due to the increase in revenues (accounting for 90%) compared to  the total insurance value (accounting for 10%). Overall, we show that  farmers benefit economically from plant species diversity and that even a  moderate increase in this diversity contributes to more stable  grassland-based production. Thus, our results are highly relevant for  future sustainable intensification of grassland-based production.<\/p>\n\n\n\n<h3><strong>Reference<\/strong>:<\/h3>\n\n\n\n<p> Schaub, S., N. Buchmann, A.
