Modelled arable area for Great Britain under different climate and policy scenarios

The dataset contains model output from an agricultural land use model at kilometre scale resolution over Great Britain (GB) for four different climate and policy scenarios. Specifically, arable area is modelled for with or without a climate tipping point (standard (medium emissions scenario SRES-A1B) climate change vs Atlantic Meridional Overturning Circulation (AMOC) collapse) and with or without widespread irrigation use for farmers from 2000 to 2089.

本数据集包含针对大不列颠（Great Britain）全域、采用公里级分辨率（kilometre scale resolution）的农业土地利用模型（agricultural land use model）输出结果，共覆盖四种不同的气候与政策情景。具体而言，模型针对耕地面积（arable area）开展模拟，其模拟考量了两类气候情景：采用标准中等排放情景SRES-A1B（medium emissions scenario SRES-A1B）的常规气候变化场景，以及触发大西洋经向翻转环流（AMOC，Atlantic Meridional Overturning Circulation）崩塌的气候临界点场景；同时包含两类农户灌溉情景：是否采用大规模灌溉。模拟时段为2000年至2089年。
