R project to assess the environmental impacts of the main Spanish crops at a regional level

The collated data correspond to the parameters to estimate the resources consumption and the emissions to the environment from the main farming activities (resources consumption and emissions from infrastructure building and management, fertiliser and pesticide production, on-field fertiliser and pesticide emissions, fuel consumption from machinery use, and irrigation), together with the environmental impacts of the unit processes (e.g. electricity mix, production of agricultural inputs) required to assess the environmental impacts from a panel of reference holdings at the main NUTS 2 in Spain. These data were compiled in a set of excel sheets and subsequently operated (tidying, transforming, visualisation and modelling operations) by developing a set of scripts using R programming language and the RStudio interface.本整理所得数据集包含两类核心内容：一是用于估算主要农业活动资源消耗与环境排放的参数，涵盖基础设施建设与运维、化肥与农药生产、田间化肥农药排放、农机使用燃油消耗及灌溉等环节的资源消耗与排放；二是评估西班牙主要NUTS 2级区域参考农场群环境影响所需的单元过程环境影响（如电力结构、农业投入品生产）。本数据集首先以多张Excel工作表完成汇编，随后通过编写基于R编程语言及RStudio集成开发环境的脚本，开展数据清洗、转换、可视化及建模等处理操作。
