A systematic review of countries producing the most scientific literature on digital technologies in agriculture
摘要
Digital technologies have undeniable potentials in enhancing agricultural resilience to climate change and food security through improved precision in resource management, real-time crop monitoring, and data-driven decision-making. Research on this topic does not currently provide a holistic picture of how these technologies are used by countries that produce the most scientific literature. This hinders comprehensive understanding of the patterns of research in this domain. This study aims to fill this research gap by providing a holistic picture of the status of digital agriculture across countries that publish the most scientific literature on this topic. This work employs a systematic tracking approach across six regions, selecting the top five countries from each region based on publication volume in this field. A total of 1259 articles were analyzed to identify digital technologies reported in agricultural research literature across the selected countries. Thirteen digital technologies are recorded in the scientific literature, of which the six most reported are web/mobile applications and software (36%), cameras (32%), sensors (28%), drones (18%), smartphones (6%) and satellites (6%). The results show further that the main data inputs for digital agriculture technologies include images/videos (76%), which are analyzed predominantly through machine learning approaches. China and the United States of America are the only countries where all thirteen technologies are found, reflecting their dual leadership in research investment and technology production. Asia is the top region in terms of both utilization (52%) and research financing (61%). In North America and the Caribbean, the United States and Canada contribute the highest to the development of digital technologies which stands at about 37.2%. Although Africa remains underrepresented in digital agricultural technology development, South Africa and Morocco make notable contributions to research funding. The study reveals limited inclusive collaboration frameworks for digital technology development, particularly in terms of multi-stakeholder participation.
