Executive Summary
The 2023–2024 El Niño event imposed a significant climate debt on key Arabica-producing regions. While agronomic conditions have partially recovered, our multi-temporal analysis of Sentinel-2 NDVI and MODIS Land Surface Temperature data reveals that moisture deficit stress persists across an estimated 340,000 hectares of prime Arabica-growing terrain in Brazil's Cerrado Mineiro and Sul de Minas sub-regions.
Key finding: Vegetation stress indices remain 1.8–2.3 standard deviations below the 2015–2023 baseline across the most climatically impacted zones — a signal historically associated with 12–18% yield suppression in the following harvest cycle.
Satellite Data Sources & Methodology
This analysis integrates four satellite data streams captured between August 2024 and February 2025:
- Sentinel-2 MSI — 10m resolution NDVI, EVI, and SWIR composites (10-day return intervals)
- MODIS Terra/Aqua — LST Day/Night products (MOD11A2), 8-day composites
- CHIRPS Precipitation — Daily rainfall estimates at 0.05° resolution
- ERA5-Land — Soil moisture and evapotranspiration reanalysis
Regional Analysis
Brazil — Minas Gerais
The Cerrado Mineiro PDO and Sul de Minas regions show the most pronounced post-El Niño stress fingerprint. NDVI anomaly maps computed against the 2015–2023 climatological baseline show persistent below-normal vegetation greenness in the critical August–November flowering and cherry-set window.
| Sub-Region | NDVI Anomaly (σ) | Affected Area (ha) | Risk Rating |
|---|---|---|---|
| Cerrado Mineiro | −2.1 | 187,000 | HIGH |
| Sul de Minas | −1.8 | 153,000 | ELEVATED |
| Chapada de Minas | −1.2 | 68,000 | MODERATE |
| Matas de Minas | −0.7 | 29,000 | LOW-MODERATE |
Colombia — Huila & Nariño
The Colombian picture is more complex. Huila — responsible for approximately 14% of Colombian export volumes — shows bimodal stress patterns consistent with ITCZ displacement. The mitaca (secondary harvest) cycle appears particularly impacted, with flowering failure indicators present across the northern slopes of the Macizo Colombiano.
Futures Market Implications
Integrating these geospatial stress signals with our probabilistic yield model produces a Q3 2025 supply outlook that diverges materially from current CONAB and ICO consensus estimates. Our model indicates:
- Brazilian Arabica production risk skewed to the downside by 8–14% relative to current trade estimates
- Colombian washed Arabica supply tightening in H2 2025 as mitaca shortfall becomes visible in export data
- Combined effect supports a bullish structural backdrop for ICE "C" futures through Q2–Q3 2025

Methodology Notes
All satellite composites are cloud-masked using the Sentinel-2 Scene Classification Layer (SCL) and MODIS MOD35 cloud mask. Anomaly calculations use a pixel-level z-score approach against the 2015–2023 growing-season baseline. Spatial aggregation to administrative boundaries uses the IBGE/DANE municipal polygon datasets.
