102 Assessing the Needs of the World’s Most Food-Insecure Countries In 2022, it was the onset of the ongoing conflict in Ukraine. In 2023, it was extreme heat across many countries and fall armyworms munching maize crops across southern Africa. These leading causes of food insecurity are just a few of the crises in focus for the Food and Agriculture Organization of the United Nations (FAO). The Data in Emergencies (DIEM) team uses satellite imagery, data collected from the field, and advanced spatial analysis and mapping to investigate root causes and mitigation strategies to reduce food insecurity. People are living in situations where they are constantly being hit by something. You can have a flood followed by a livestock disease outbreak and, at the same time, have conflict breaking out and the currency plunging. —Neil Marsland, head of the DIEM team at FAO in Rome Enumerators and local residents in the northwest of the Syrian Arab Republic assess the damage following a devasting earthquake. @FAO
