This document provides an overview of the IoF2020 project, which aims to foster large-scale adoption of IoT technologies in European farming and food production. The project objectives are to (1) demonstrate IoT's business value across various farming and food applications, (2) integrate and reuse available IoT technologies through open standards, and (3) ensure user acceptability by addressing needs like security, privacy and trust. A lean multi-actor approach will be used to conduct trials of IoT use cases in areas like arable, vegetables and dairy farming. The project aims to establish an IoT ecosystem to support large-scale adoption beyond the lifetime of the project.
