IIASA researchers win GEO Appathon

Growers’ Nation, a mobile app developed by Ecosystems Services and Management researchers, won the 2014 Group on Earth Observations (GEO) Appathon, a global app development competition.



The winning app uses data such as temperature, precipitation, elevation, and slope, which were available from the GEOSS portal, to help gardeners and small-scale farmers determine what to plant and when. The communication features encourage farmers to share information and build a community of growers. One goal of the app is to help reduce food insecurity [1] in developing countries by providing information to farmers to help boost crop yields and production, for example, by encouraging farmers to plant diverse crops.
