- Method / resource Models explained a wide range of variability in the crop outcomes across crops and zones (approximately R2 0.55 to 0.99).
- Method / resource Quinoa showed the most consistent model fits, with several outcomes at R2 above 0.90.
- Observation The Southern zone had 1–5 dry spells of at least 5 days per year.
- Association Heat-day frequency showed non-significant declines across zones in 2015–2022.
- Observation Reanalysis frost days were virtually zero.
- Mechanism The near-zero reanalysis frost days are consistent with under-detection of local valley frosts at coarse resolution.
- Association Vulnerabilities in the South are driven by precipitation.
- Recommendation Quinoa is supported as a resilient option under increasing climate stress.
