## 📋 Editorial Notes
- **Today's Theme:** Field Deployments & Case Studies — focus on AI tools that are LIVE in the field, with real numbers
- **Dedup Applied:** GANNET (eps 19, 22, 23, 24, 26), WFP West Africa food (ep 25, 26), UNDP satellite (ep 26), EU AI Act (ep 25, 26), Lebanon (eps 22-24, 26), IRC (eps 21-24), UNICEF deepfakes (ep 21), ASEAN framework (ep 25) — all SKIPPED
- **Story Queue:** No active queued stories (both used; one cancelled)
- **Geographic Balance:** 2× Caribbean, 1× South Asia, 1× Global/Africa, 1× Global — fills Caribbean and South Asia gaps ✓
- **Recovery Gap:** Recovery-phase story not found today; best candidates were non-AI (Friday/Thursday REQUIRED — not today)
- **Political Filter:** IMF AIPI story reviewed — not political, operational structural data. INCLUDED.

## 📰 Story 1: AI Probabilistic Monsoon Forecasts Reached 38 Million Indian Farmers in 2025
**Source:** arXiv 2603.07893 (published March 9-10, 2026) — "Designing probabilistic AI monsoon forecasts to inform agricultural decision-making"
**Category:** Preparedness / Field Deployment
**Geography:** India / South Asia
### What Happened
Researchers published a new paper documenting a 2025 operational deployment of an AI-powered monsoon onset forecasting system that reached **38 million Indian farmers** through a government-led program.
The system blends AI weather prediction models with a Bayesian "evolving farmer expectations" statistical model — predicting the time-varying probability of monsoon onset throughout a season. In 2025, it successfully predicted an early-summer anomalous dry period, giving farmers actionable lead time before planting decisions and investment commitments.
The core innovation: this is NOT a single prediction — it's a decision-theory framework that tailors forecasts to farmers' heterogeneous circumstances. Rather than prescribing a single "plant now" date, it delivers probability distributions that farmers (with different crops, resources, and risk tolerance) can act on independently.
### Key Stats
- 38 million farmers reached, India, 2025
- Operationally deployed via government-led subseasonal forecast program
- Blended system outperforms any single model OR multi-model average on Indian monsoon
- Addresses: high-stakes planting decisions, agricultural investment under weather uncertainty
### Why It Matters for Practitioners
- **Template for scale**: demonstrates how AI + Bayesian blending delivers more skillful subseasonal climate forecasts for agricultural resilience — a model for other tropical countries
- **Decision theory lens**: the framework asks "what information helps DIFFERENT farmers with DIFFERENT options?" — not one-size-fits-all
- **Lead time gains**: longer useful forecasts at subseasonal range directly improves anticipatory action windows

## 📰 Story 2: CERES — Open-Access Famine Early Warning System for 43 High-Risk Countries
**Source:** arXiv 2603.09425 (published March 10, 2026) — "A Probabilistic Early Warning System for Acute Food Insecurity"
**Category:** Preparedness / Technology Innovation
**Geography:** Global (43 countries)
### What Happened
A new automated, probabilistic famine early warning system called **CERES** (Calibrated Early-warning and Risk Estimation System) was published on arXiv March 10. It generates **90-day-ahead probability estimates** of IPC Phase 3+ (Crisis), Phase 4+ (Emergency), and Phase 5 (Famine) conditions for 43 high-risk countries — updated weekly.
CERES fuses **six data streams**: precipitation ano
