Situation Report: Colombia's Cacao Emergency

Report by: Emma Lozano

KEY MESSAGES

• Systemic Lowland Vulnerability: The Caribbean lowlands (Córdoba/Magdalena) face a long-term suitability crisis. Recent JANUS modeling and scientific reports (March 2026) indicate that nearly 20% of current cacao-growing areas in these low-lying zones could be lost due to intensifying flood-drought cycles. [S001]
• Physiological Tipping Point: Cacao trees in the Caribbean are reaching a critical threshold for root anoxia. Stagnant water for >6 days in the San Jorge and Sinú basins is causing irreversible chlorophyll degradation and root rot. [S002]
• Flash-Flood Hazard: In the Foothills (Villavicencio), the risk is acute rather than systemic. The 12.68% expected exposure for cacao is driven by high-energy "Flash Floods" that cause immediate flower cushion damage and soil erosion, threatening this season's yield. [S003]

1. SITUATION OVERVIEW

This report evaluates the differential impact of the 2026 flood emergency on Colombia’s cacao sector. While the Caribbean region faces a geographic redistribution of the crop due to rising water tables, the Foothills remain a strategic "stability core" currently under acute pressure from Andean runoff.

The event is occurring during a declared National Economic Emergency (Feb 2026), with over 157,000 hectares of farmland submerged nationwide. [S004, S005]

2. HAZARD ANALYSIS: JANUS Methodology

The model operates through a Posterior-weighted Bayesian fusion:

• The Past (Priors): Multi-decadal flood density maps and terrain embeddings capturing the "memory" of the landscape.
• The Future (Hazard): Real-time 72-hour GFS forecast and NASA SMAP soil saturation indicators.
• Specific Factors:
• Caribbean: Focus on Soil Water Content (SWC). When SWC is 75% above field capacity, cacao dry matter reduces by 34%.
• Foothills: Focus on Runoff Velocity. High-energy water in the Andean foothills destroys "flower cushions," the primary source of fruit production.

4. SECTOR ANALYSIS: CACAO

4.1 The Caribbean "Red Zone" (Córdoba / Magdalena)

Evidence suggests that the northern lowlands are the most vulnerable. The JANUS model reflects that stagnant water conditions are the primary threat here.

• Anoxia: Trees are attempting to adapt by forming hypertrophied lenticels for oxygen intake, but sustained flooding beyond 10 days leads to total root failure.
• Context: Córdoba is currently the epicenter of the crisis, with 80% of the department flooded. [S004]

4.2 The Foothills "Stability Core" (Villavicencio/Meta)

In contrast, the Andean foothills are projected to remain a long-term "refuge" for the industry.

• Acute Risk: The 12.68% exposure is a temporary spike caused by the 2026 cold front.
• Recovery: Better drainage means root systems recover ~80% of photosynthetic capacity within 10 days of the water receding, provided the flower cushions were not physically stripped.
