Multiple cropping area estimate by region and country.

This table summarizes published multiple cropping area estimates for selected countries and regions. Multiple cropping refers to any agricultural systems in which multiple crops are combined and includes certain types of agroforestry, cover cropping, crop rotations, double and triple cropping and intercropping. The area estimates in the literature are based on national survey statistics, expert opinions, suitability analysis, remote sensing, self-reported cropping practices and other methods. Area estimates are provided as physical area in hectares and million hectares, and as percentage of total cropland, crop area, arable land or agricultural land.

本表格汇总了针对部分国家与地区发布的多熟种植（multiple cropping）面积估算结果。多熟种植指将多种作物组合种植的各类农作系统，涵盖部分农林复合系统、覆盖作物种植、作物轮作、双季与三季种植以及间作等模式。现有文献中的面积估算结果基于国家调查统计数据、专家意见、适宜性分析、遥感技术、自主上报的种植模式及其他方法得出。本次提供的面积估算结果以公顷、百万公顷为物理面积单位，同时以总耕地、作物种植面积、可耕地或农业用地的占比形式呈现。
