A growing global need for food and the environmental impact of agriculture has led to an increase in the use of electronics, information technology, and telecommunications in this sector. To gain insights and consolidate knowledge on the intersection of IoT, agriculture, and climate change, a bibliometric analysis was conducted on 68 documents extracted from the Web of Science database, utilizing the bibliometrix and biblioshiny programs. It was evident through the analysis that there had been a notable surge in interest in the subject, as indicated by the increasing number of publications and research groups dedicated to the area. These findings shed light on the most significant contributions published to date within the interconnected realm of IoT, agriculture, and climate change.
