Unmanned aerial vehicles for agriculture: an overview of IoT-based scenarios

The agricultural sector is experiencing a new revolution, giving birth to the so-called Agriculture 4.0 paradigm. It brings digital technologies in the field to support the farmers' work, enhancing the productivity of farms. In this chapter, the attention is focused on the role that both Internet of Things (IoT) and Unmanned Aerial Vehicles (UAVs) can play in this regard, whether used in a joint manner or not. We analyse the work being done both in recent research projects and in the literature on those topics, taking into account the role of long-range wireless communications to enable such scenarios, and the potential of 5G and the upcoming Multi-Access Edge Computing (MEC) technology, especially in rural areas, where the lack of connectivity is still hampering the process of digital transformation.
