VIPS is an Open Source technology platform for prognosis, monitoring and decision support in agriculture. Data from most online weather stations, public weather data networks and weather forecasts can be used, allowing pest and disease models to be tested and validated under local conditions, with multiple sources of input data. Observations of pests and diseases can be easily registered with smartphones and reported using online maps. We aim to initiate international research collaboration to create new and improved tools for better implementation of integrated pest management.
