Drought AA indicators site

Cross-country backtest (2001-2024) of temperature, rainfall, water-balance and vegetation indicators against six drought-impact ground truths (FAOSTAT staple production, CERF/EM-DAT drought seasons, framework-documented bad years, FEWS NET official subnational yields nationally and in framework areas, GDHY gridded yields) across the ten OCHA drought-AA countries. Primary output is one pooled matrix (LOO/LOYO R² for continuous targets, within-country AUC for binary). Detrended growing-season temperature and FAO ASI/VHI lead on production shortfalls (LOO R² 0.13-0.15 vs 0.02 for the ASAP biomass anomaly Burkina Faso's observational trigger keys on); rainfall/SPI-3 lead on the binary records (AUC 0.62-0.64 impact seasons, 0.76-0.78 bad years); within provinces no indicator exceeds LOYO R² 0.04. Recommends adding temperature to every observational-window candidate set alongside ASI/VHI and a rainfall arm.
