AI-Powered Food Insecurity Early Warning System

HarvestGuard is an open-source platform that fuses real satellite vegetation data, rainfall anomalies, and WFP food security indicators to generate AI-powered 30-60 day early warnings of crop failure and food insecurity — accessible to NGOs, governments, and humanitarian responders worldwide.

The Problem

828 million people face food insecurity. Smallholder farmers (who produce 70% of the world's food) have zero access to advance crop failure warnings. WFP's HungerMap shows current status; FEWS NET publishes monthly expert reports. No open, accessible platform provides real-time predictive intelligence at country level.

HarvestGuard fills this gap.

How It Works

NASA MODIS NDVI  ──┐
CHIRPS Rainfall  ──┤──► Risk Engine ──► Claude AI ──► Risk Assessment + Alerts
WFP HungerMap    ──┘                              ──► Conversational Analysis
Open-Meteo       ──┘
  1. Real satellite data — NASA MODIS vegetation indices updated every 16 days
  2. Rainfall anomalies — CHIRPS precipitation vs 1981-2010 historical baseline
  3. Ground truth — WFP HungerMap IPC phases and affected population counts
  4. AI analysis — Claude generates plain-language risk assessments from real data
  5. Early warnings — Alerts fire when composite risk scores deteriorate significantly

Data Sources (100% Real, No Synthetic Data)

Source Data Update Frequency
NASA MODIS MOD13A2 NDVI/EVI vegetation indices 16 days
CHIRPS Precipitation anomalies (1981-present) Monthly
WFP HungerMap IPC phases, affected populations 6 hours
Open-Meteo Historical & forecast weather Daily

Features

  • Interactive World Map — 60+ countries color-coded by IPC risk phase
  • Real-time NDVI & Rainfall — Satellite vegetation health and precipitation anomaly trends
  • AI Risk Assessments — Claude-powered streaming analysis with real data context
  • Early Warning Alerts — Automatic detection of deteriorating food security
  • Trend Charts — 90-day NDVI + rainfall history per country
  • AI Chat — Ask "What's happening in Ethiopia?" and get data-grounded answers

Quick Start

Prerequisites

1. Clone and configure

git clone https://github.com/rishavsunny12/claude-code-tp
cd claude-code-tp
cp .env.example .env
# Edit .env — set ANTHROPIC_API_KEY

2. Launch

docker compose up --build

3. Seed real data

# Trigger the first data refresh (fetches WFP + weather data)
curl -X POST http://localhost:8000/api/v1/admin/refresh

4. Open the app

Navigate to http://localhost:3000

Click any country on the map to see:

  • Current IPC phase and affected population
  • NDVI and rainfall anomalies vs historical baseline
  • 90-day trend chart
  • Live-streaming Claude AI risk assessment

API Reference

Endpoint Description
GET /api/v1/regions All monitored countries with current risk scores
GET /api/v1/regions/{iso} Full country detail with 90-day history
GET /api/v1/forecast/{iso} Stream AI risk assessment (SSE)
GET /api/v1/alerts Active food security alerts
POST /api/v1/chat Conversational AI query (SSE)
GET /health Health check

Optional: NASA Earthdata (Enhanced NDVI)

For higher-accuracy NDVI from actual MODIS raster data:

  1. Register free at urs.earthaccess.nasa.gov
  2. Add EARTHDATA_USERNAME and EARTHDATA_PASSWORD to .env

Without credentials, NDVI is estimated from Open-Meteo weather correlates (still useful as a proxy).
