生产能源作物作为化石燃料的替代品以减少二氧化碳排放将导致农业景观的大规模变化。在这里,我们通过高分辨率(25 × 25米)的土地利用情景来量化玉米田增加对农田鸟类多样性的潜在影响。我们生成的情景中,玉米生产的面积在德国从目前的2.6增加到2.9,3.6和4.3万公顷,对应的能源作物生产目标的德国可再生能源法为2020年,2035年和2050年。为了测试保护措施的缓解潜力,每种情景都以标准版本和景观保护版本生成,后者不包括将宝贵的农田区域转化为玉米田。在德国,属于政府可持续土地利用指标计划的9种农田鸟类被模拟为6个全国范围的情景。这些模型预测,只有北方麦鸡和小猫头鹰可能从扩大玉米生产中获益。尽管如此,在最密集的情况下,预测指标物种的繁殖对总数将减少约40万对。在模型中,保护宝贵的农田并没有减轻这些负面影响。我们的研究结果表明,能源作物产量的增加与生物多样性的保护相冲突。
Producing energy crops as an alternative to fossil fuels in order to reduce CO2emissions will lead to large‐scale changes in agricultural landscapes. Here, we quantify the potential impact of an increase in maize fields on the diversity of farmland birds by means of high resolution (25 × 25 m) land‐use scenarios. We generated scenarios in which the area of maize production in Germany increases from presently 2.6 to 2.9, 3.6 and 4.3 million ha, corresponding to the energy crop production targets of the German Renewable Energy Act for the years 2020, 2035 and 2050. To test the mitigating potential of conservation measures, each scenario was generated in a standard version and a landscape protection version, with the latter excluding valuable farmland areas from being converted into maize fields. Nine species of farmland birds belonging to the governmental indicator scheme for sustainable land‐use in Germany were modelled for the six nation‐wide scenarios. The models predicted that only the Northern Lapwing and the Little Owl might profit from extended maize production. Despite this, the total number of breeding pairs of the indicator species was predicted to decline by about 0.4 million breeding pairs in the most intensive scenario. Protection of valuable farmland did not mitigate these negative effects in the models. Our findings suggest that increased production of energy crops conflicts with conservation of biological diversity.
