Spatial-Temporal Evolution of Scientific Production about Genetically Modified Maize

Abstract

Maize is the grain cereal that is the basis of human and animal diets in Mexico and Latin America; it constitutes an essential crop for global food security. The objective of this study was to analyze the spatial–temporal evolution of scientific production on the theme of GMO maize, through a bibliometric analysis of the texts available in the main editorial houses (Elsevier, Scopus, and Springer), open access journal articles database (Conricyt, Scielo, Redalyc, Latindex, Claryvate Analytics, Periodica, and DOAJ), and freely accessible web search engine Google Scholar, to determine the factors that influence the impact of the studies. From 1991 to 2019, 917 texts were found whose spatial–temporal evolution showed a linear growth that concentrated in Latin America (58.56%). The low impact (measured by the number of bibliographic citations) of scientific studies developed in countries of Latin America was related to their publication in journals edited in their own countries and in Spanish, which restricts the constructive criticism of peer review. For the case of Mexico, a spatial discrepancy was also found between research centers and production areas, which limits the transference of technology; and no specialized author in theme of GMO maize was found; the researchers responded to “scientific trends” in agreement with the agrarian policies of the time.

Research Progress of Nucleic Acid Detection Technology for Genetically Modified Maize

“…Maize is important in the food industry because of its nutritional characteristics and wide applications in the food industry. At the same time, maize is the food crop with the largest production volume (tons) in the world [1], and, thus, it is considered to be a strategic crop for national food security by many countries [2]. Therefore, the continuous demand for maize products has driven an increase in its production.…”

Relationship between Maize Seed Productivity in Mexico between 1983 and 2018 with the Adoption of Genetically Modified Maize and the Resilience of Local Races

“…The objective of the PROCAMPO program was not only to increase grain maize production through the increase of the surface planted (ha), but also to standardize the property rights on the land [9]; meanwhile, the MasAgro program attempts to make social agriculture for subsistence more productive, to satisfy the demands of the grain and family supply [11]. In contrast with these two programs that have been applied, the strategy of producing genetically modified maize varieties to increase the yields in the field has not been implemented [12].…”
