了解在哪里、何时以及多少水稻被种植和收获，对于理解政策、贸易以及全球和技术变化对粮食安全的影响是至关重要的信息。我们开发了RiceAtlas，这是一个关于世界稻米产量季节分布的空间数据库。它包括按生长季节分列的水稻播种和收获日期数据，以及所有水稻生产国的月产量估计数。用于种植和收获日期的来源包括全球和区域数据库、国家出版物、在线报告和专家知识。月度生产数据是根据年度或季节性生产统计数据以及种植和收获日期估计的。RiceAtlas有2725个空间单位。与现有的全球作物日历相比，RiceAtlas的空间细节增加了近十倍，空间单元增加了近七倍，至少有两个季节的日历数据，使RiceAtlas成为关于水稻日历和生产最全面、最详细的空间数据库。
Knowing where, when, and how much rice is planted and harvested is crucial information for understanding the effects of policy, trade, and global and technological change on food security. We developed RiceAtlas, a spatial database on the seasonal distribution of the world’s rice production. It consists of data on rice planting and harvesting dates by growing season and estimates of monthly production for all rice-producing countries. Sources used for planting and harvesting dates include global and regional databases, national publications, online reports, and expert knowledge. Monthly production data were estimated based on annual or seasonal production statistics, and planting and harvesting dates. RiceAtlas has 2,725 spatial units. Compared with available global crop calendars, RiceAtlas is nearly ten times more spatially detailed and has nearly seven times more spatial units, with at least two seasons of calendar data, making RiceAtlas the most comprehensive and detailed spatial database on rice calendar and production.
