How might we support farmers in making sense of water quality data in relation to non-digital information around their farm? What type of relationship between farmers and technicians shall we support and how? These are the questions that my team had to explore during a week in Purworejo, Central Java. We shadowed field technicians, shrimp farmers, and visited harvest collection centers all along the southern coast of Jogjakarta. The work for Jala Tech involved field observations, interviews, product testing and prototyping.
