The main goal of this study is to conduct a literature review on the research carried out in response to the innovative and disruptive technology of Unmanned Aerial Vehicles (UAVs) and its development in the field of smart agriculture (SA). The aim is to create a coherent taxonomy of the research landscape and identify the key characteristics of this emerging field, including the motivations for utilizing UAVs, the unresolved challenges, and the recommendations for future progress. We performed a targeted search for papers on UAVs and their development, specifically focusing on their use in the context of applications in in SA. The search was conducted in three significant databases: Web of Science, ScienceDirect, and IEEE Xplore. These databases are deemed adequately thorough to include both SA and technical literature. The final set of articles consisted of a total of 64 items. The maj ority of articles consist of reviews and surveys that reference studies conducted on agriculture and their applications. Another group of articles propose frameworks for the development and operation of drones in the agriculture sector. Additionally, there are experimental studies that present subsections such as analysis studies, evaluation studies, and comparison studies. Between 2015 and 2024, researchers closely monitored the development and advancements of UAV s within SA. Nevertheless, there are specific places and components that necessitate further investigation. Regardless of their category, publications focus on the barriers that hinder the effectiveness of UAVs in situational awareness and propose strategies to alleviate them.
