+## Data Generation Methodology
+
+This dataset was synthetically generated using:
+
+1. **Reference Sources**:
+   - FAO (Food and Agriculture Organization) - crop yields, production data
+   - NBS (National Bureau of Statistics, Nigeria) - farm characteristics, surveys
+   - NiMet (Nigerian Meteorological Agency) - weather patterns
+   - FMARD (Federal Ministry of Agriculture and Rural Development) - extension guides
+   - IITA (International Institute of Tropical Agriculture) - agronomic research
+
+2. **Domain Constraints**:
+   - Crop calendars and phenology (planting/harvest windows)
+   - Agro-ecological zone characteristics (Sahel, Sudan Savanna, Guinea Savanna, Rainforest)
+   - Nigeria-specific realities (smallholder dominance, market dynamics, conflict zones)
+   - Statistical distributions matching national agricultural patterns
+
+3. **Quality Assurance**:
+   - Distribution testing (KS test, chi-square)
+   - Correlation validation (rainfall-yield, fertilizer-yield, yield-price)
+   - Causal consistency (DAG-based generation)
+   - Multi-scale coherence (farm → state aggregations)
+   - Ethical considerations (representative, unbiased)
+
+See `QUALITY_ASSURANCE.md` in the repository for full methodology.
+
+## Use Cases
+
+- **Machine Learning**: Yield prediction, price forecasting, pest detection, supply chain optimization
+- **Policy Analysis**: Agricultural program evaluation, subsidy impact assessment, food security planning
+- **Research**: Climate-agriculture interactions, market dynamics, technology adoption patterns
+- **Education**: Teaching agricultural economics, data science applications in agriculture
+
+## Limitations
+
+- **Synthetic data**: While grounded in real distributions, individual records are not real observations
+- **Simplified dynamics**: Some complex interactions (e.g., multi-generational pest populations) are simplified
+- **Temporal scope**: Covers 2022-2025; may not reflect longer-term trends or future climate scenarios
+- **Spatial resolution**: State/LGA level; does not capture micro-level heterogeneity within localities
