Researchers have developed a novel dataset and applied machine learning models to forecast weather-driven price dynamics in Sri Lanka's tea market. Analyzing four main tea catalogues—High Grown, Low Grown, Off-Grade, and Dust—using data from broker reports and weather patterns, the study found that while market dynamics are primary drivers, weather conditions significantly influence prices. Specifically, Low Grown tea showed sensitivity to precipitation and sunshine, while Off-Grade and Dust teas responded to temperature variations. The study concluded that catalogue-specific modeling, particularly with LightGBM, outperformed unified approaches, offering a more precise forecasting framework for the tea industry. AI
IMPACT Provides a more precise forecasting framework for the tea industry by integrating weather data with catalogue-specific ML models.
