Agricultural drought research knowledge graph reasoning by using VOSviewer

Area of Science:

• Agricultural Science
• Environmental Science
• Bibliometrics

Background:

• Agricultural drought (AD) poses a significant threat to global food security and agricultural systems.
• Existing research has focused on causes, monitoring, and impacts, but lacks a systematic overview of AD knowledge development.
• A comprehensive bibliometric analysis is needed to understand the evolution and trends in AD research.

Purpose of the Study:

• To systematically investigate the development of agricultural drought (AD) research.
• To analyze the relationships between AD and related knowledge domains.
• To identify current research hotspots and future directions in AD studies.

Main Methods:

• A comprehensive literature search was conducted on the Web of Science (WoS) database.
• Publications from 2020 to 2023 were prioritized for analysis.
• Bibliometric analysis was performed using VOSviewer software to map research trends, collaborations, and keywords.

Main Results:

• A total of 7416 articles on AD were identified, with a notable acceleration in publications since 2020.
• China and the USA are the leading contributors, with research published across 457 journals.
• Keywords such as climate change, yield, variability, impact, growth, and adaptation highlight current research focus.

Conclusions:

• The study reveals a rapidly expanding body of literature on agricultural drought.
• It identifies key research hotspots and outlines promising future research directions.
• This bibliometric analysis offers a valuable guide for researchers in the agricultural drought field.
