This document describes the development of an agri-data warehouse to store pest scouting data collected from farms. Data was initially collected via handwritten forms which were then typed into a digital format, introducing errors. The data was then transformed and loaded into a central database to be queried and generate reports. This allowed identification of correlations between pest populations and treatments, validation of scouting data, and insights into optimal sowing and spraying dates. Key lessons learned included addressing data quality issues and the need for decision support all the way down to extension workers.
