Abstract
This article empirically provides a scientific production trends overview of coffee agronomy at the global level, allowing us to understand the structure of the epistemic community on this topic. The knowledge contributions documented are examined using a bibliometric approach (spatial, productive, and relational) based on data from 1618 records stored in the Web of Science (JCR and ESCI) between 1963 and May 2021, applying traditional bibliometric laws and using VOSviewer for the massive treatment of data and metadata. At the results level, there was an exponential increase in scientific production in the last six decades, with a concentration on only 15 specific journals; the insertion of new investigative peripheral and semiperipheral countries and organizations in worldwide relevance coauthorship networks, an evolution of almost 60 years in relevant thematic issues; and a co-occurring concentration in three large blocks: environmental sustainability of forestry, biological growth variables of coffee, and biotechnology of coffee species; topic blocks that, although in interaction, constitute three specific communities of knowledge production that have been delineated over time.
Highlights
This article empirically analyzes the global trends of research in coffee agronomy in terms of its evolution over time, the sources of documentation of scientific production, the geography of knowledge generation, and the topics under study
We used a set of articles as a homogeneous basis for citation, counting the main collection of Web of Science (WoS) [82], by selecting articles published in WoS-indexed journals in the Science Citation Index (WoS-SCI), Social Science Citation Index (WoS-SSCI), and Emerging Science Citation Index (WoS-ESCI) based on a search vector [83] about coffee (TS = coffee) restricted to the WoS Agronomy category (WC = agronomy) and with unrestricted time parameters, performing the extraction on 22 May 2021 (See Table S1)
This article empirically contributes to establishing a general overview of the trends in the scientific production of coffee agronomy at the global level, which allows us to un4
Summary
This article empirically analyzes the global trends of research in coffee agronomy in terms of its evolution over time, the sources of documentation of scientific production, the geography of knowledge generation (national and organizational), and the topics under study. With increasing patterns of climate variability, water resources for agriculture may become more unpredictable and scarcer [30,31,32,33] For this reason, the presence of shade trees (adequate pruning), the reuse of secondary treated wastewater (with fertilizer management and adequate nutritional conditions), irrigation performance and management (depths and technologies), and groundwater balance seek to reduce soil evaporation and coffee transpiration as measures to preserve water within the agroecosystem [2,34,35,36,37,38,39,40]
