Holistic Model for Designing a Climate Service Application on the KaiOS Platform.

Interest towards building and operating climate services is constantly growing globally, especially regarding utilization of mobile technologies in those services in the Global South, in order to reach rural farmers effectively. However, multiple issues are currently limiting the design and development of these services for reaching their full impact. Based on a recent field study, we present the criteria for a mobile climate service app for small-scale farmers in Namibia. It will be based on the KaiOS "smart feature phone" platform, and combines holistically climate, weather and agricultural information in a form that guides the farmer through the agricultural cycle. The app is currently in its early development phase, with a set of pre-selected features being built. Further field work with the local farmers will define the final set of features and the eventual user interface (UI) design of the app.
