Data and models for papers: "Does scale matter?" and "The environmental impacts of the scale of circularity in food systems"

Datasets and models used for the papers: ' Does scale matter? How local sourcing of food affects land use in circular food systems in the Netherlands.' &amp; 'The environmental impacts of the scale of circularity in food systems'<br>Includes the calculation procedures for: Classification of the biophysical production environment into suitability zonesCalculation of zone-specific crop yields and N flows for a range of food and feed cropsAssessment of the impacts of local (provincial) sourcing of food on land use, N losses and GHG emissions in circular food systems in the Netherlands<br>Note that feed data used in the study is confidential and is therefore not included in the database, which could impede (parts of) the model from running. Also, scripts on results processing for Phosphorus were unfinished, as they were not used for the paper, and therefore omitted.

本数据集与模型用于以下两篇学术论文：《Does scale matter? How local sourcing of food affects land use in circular food systems in the Netherlands.》与《The environmental impacts of the scale of circularity in food systems》。
本数据集包含以下计算流程：将生物物理生产环境划分为适宜性分区的方法；针对多种食用与饲料作物，计算分区专属作物产量及氮（N）流动量的流程；评估荷兰循环食品系统中，本地（省级层面）食品采购对土地利用、氮素流失及温室气体（GHG）排放的影响的方法。
需注意，本研究中使用的饲料数据属于机密内容，因此未纳入数据库，这可能会导致模型（部分功能）无法正常运行。此外，针对磷（P）的结果处理脚本尚未完成，且未在论文中使用，故未提供。
