Abstract
In this work, an exhaustive revision is given of the literature associated with advanced information and communication technologies in agriculture within a window of 25 years using bibliometric tools enabled to detect of the main actors, structure, and dynamics in the scientific papers. The main findings are a trend of growth in the dynamics of publications associated with advanced information and communication technologies in agriculture productivity. Another assertion is that countries, like the USA, China, and Brazil, stand out in many publications due to allocating more resources to research, development, and agricultural productivity. In addition, the collaboration networks between countries are frequently in regions with closer cultural and idiomatic ties; additionally, terms’ occurrence are obtained with Louvain algorithm predominating four clusters: precision agriculture, smart agriculture, remote sensing, and climate smart agriculture. Finally, the thematic-map characterization with Callon’s density and centrality is applied in three periods. The first period of thematic analysis shows a transition in detecting the variability of a nutrient, such as nitrogen, through the help of immature georeferenced techniques, towards greater remote sensing involvement. In the transition from the second to the third stage, the maturation of technologies, such as unmanned aerial vehicles, wireless sensor networks, and the machine learning area, is observed.
Highlights
From the origins of humanity, man has needed to transform his environment through techniques that allow him to obtain the necessary food for his subsistence
The bibliometric analysis of the publications associated with the area of advanced information and communication technologies (ICT) in agriculture is divided into two sections
The second section is focused on discussing the results of science mapping, those derived from collaborative and co-citation networks analysis, to thematic map strategic analysis at different stages of advanced ICT in agriculture
Summary
From the origins of humanity, man has needed to transform his environment through techniques that allow him to obtain the necessary food for his subsistence. This need for food subsistence has given rise to agriculture. Agriculture has been developing through the inclusion of emerging technologies, to achieve more efficient management of agricultural inputs and a higher level of crop productivity. At the beginning of the 20th century, the integration of chemical fertilizers, mechanization, and scientific knowledge allowed a notable development of agriculture [1]. In the middle of the 20th century, the appearance of the tractor, seed improvement, and agrochemicals lead to the green revolution [2].
