Climate Variability Modulates the Impact of Price Spikes on Food Insecurity
A new study published on arXiv (2609.24394v1) finds that climate variability, particularly the El Niño Southern Oscillation (ENSO), influences how price spikes impact food insecurity in sub-Saharan Africa. The research introduces sensitivity regimes to stratify regions based on their vegetation response to ENSO and uses remote sensing, socioeconomic data, and causal machine learning to estimate the effects of price increases. In regions where ENSO suppresses vegetation, a price spike raises the acute risk population by 5.4 percentage points.
