Fig. 4. Impacts of ENSO phases on crop abandonment anomalies.
(A) Distributions of state-level crop abandonment (fab) anomalies during El Niño (red) and La Niña (blue) phases in Nebraska (NE), Colorado (CO), Kansas (KS), Oklahoma (OK), and Texas (TX). Negative and positive values indicate ENSO phases decreased and increased crop abandonment, respectively. (B) Changes in fab during the transition from El Niño to La Niña phase. Black solid circles indicate averages, and error bars represent 2.5th and 97.5th percentiles. (C) County-level changes in crop abandonment between La Niña and El Niño phases. Black dots indicate statistical significance at a 95% confidence level. Note that the state-level impact of the ENSO phase on crop abandonment was estimated by using state-level data shown in table S2.
