How do farmers manage crop biodiversity? A dynamic acreage model with productive feedback
研究了法国农民如何通过调整种植面积来利用作物生物多样性的生产能力,发现生物多样性指标影响作物产量和可变投入使用。
Previous studies on the productive value of biodiversity have emphasised that crop diversity increases crop yields. Here, we focus on the management of crop biodiversity for wheat, winter barley and rapeseed productions. We introduce productive capacity of biodiversity into a structural dynamic model with supply, variable input demand and acreage functions. We estimate the model for a sample of French farms between 2007 and 2012. We highlight that biodiversity indicators influence the yield of crops and variable input uses. We find evidence that farmers manage their acreage to benefit from the productive capacity of crop biodiversity.
