The app provides a three-month price outlook for five key commodities across Adamawa, Borno and Yobe — three conflict-affected states in Northeast Nigeria where food insecurity is most acute. No technical knowledge required.

## 📌 Project Overview
Food price volatility in Northeast Nigeria is driven by a compounding set of structural forces: the Boko Haram insurgency, the June 2023 fuel subsidy removal, naira devaluation, seasonal harvest cycles, and climate variability. Existing price monitoring systems report prices retrospectively — after market changes have already occurred.
This project addresses that gap by building a **data-driven forecasting pipeline** that predicts monthly retail food prices **up to three months in advance**, giving policymakers, humanitarian organisations, traders and farmers the lead time needed to act before a crisis arrives.
**Three models were built, evaluated and compared:**
- SARIMA — classical seasonal time series model
- XGBoost — gradient boosting with exogenous features
- Facebook Prophet — decomposable trend-seasonality model
All models were evaluated against a naive baseline across one-month, two-month and three-month forecast horizons.
