Food Insecurity Hotspots Data Set

The Food Insecurity Hotspots Data Set consists of grids at 250 meter (~7.2 arc-seconds) resolution that identify the level of intensity and frequency of food insecurity over the 10 years between 2009 and 2019, as well as hotspot areas that have experienced consecutive food insecurity events. The gridded data are based on subnational food security analysis provided by FEWS NET (Famine Early Warning Systems Network) in five (5) regions, including Central America and the Caribbean, Central Asia, East Africa, Southern Africa, and West Africa. Based on the Integrated Food Security Phase Classification (IPC), food insecurity is defined as Minimal, Stressed, Crisis, Emergency, and Famine.

《粮食不安全热点数据集》由250米分辨率（约7.2弧秒）的网格构成，这些网格揭示了2009年至2019年十年间粮食不安全程度的强度与频率，以及连续遭受粮食不安全事件的焦点区域。该网格数据基于FEWS NET（饥荒早期预警系统网络）提供的次国家级粮食安全分析，涉及五大区域，包括中美洲和加勒比海地区、中亚、东非、南非和西非。依据综合粮食安全阶段分类（IPC），粮食不安全被定义为最小化、压力、危机、紧急和饥荒五个等级。
