CPAS is Now a Website: croppas.com
I’m happy to share that the Crop Protection Analytics System (CPAS) now lives at its own home on the web: croppas.com 🎉
🌾 What is CPAS?
CPAS estimates the economic value of disease management in Australian broadacre cropping — quantifying production value lost to disease and quality downgrade, and the benefit of managing it, across GRDC agro-ecological zones, crops, and seasons.
Instead of anecdotal estimates, CPAS puts numbers on questions growers and industry ask all the time:
- How much production value is lost to a disease in a given zone and season?
- How much of that loss comes from quality downgrade rather than yield alone?
- What is the economic benefit of managing the disease, compared with leaving it untreated?
🔄 From R Shiny to a Standalone Website
CPAS started life as an internal R Shiny application, jointly developed with CCDM and SAGI West colleagues for rapid and consistent analysis of disease impact economics.
Shiny was a great environment for prototyping the analytics, but a hosted Shiny app comes with trade-offs — a running R server, session limits, and slower cold starts. Converting it to a standalone website removes those constraints: it loads fast, scales easily, and doesn’t need an R process behind every visitor.
The conversion went more smoothly than I expected — and it’s been running reliably since launch.
