# The Trends and Content of Research Related to the Sustainable Development Goals: A Systemic Review
## 1 Introduction
Health, climate change, and related water and energy issues, which correspond to SDGs 3, 13, 6, and 7, respectively, were among the focuses of academia. The term \"SDG 3\" has been explicitly included in the title of many articles, showing the authors' intention to focus on health and well-being-related issues in the framework of the SDGs [14; 15; 16; 17; 18; 19]. As climate change is becoming one of the most overwhelming challenges nowadays, numerous studies are directly connected to SDG 13 [20; 21; 22; 23] and interrelated to SDG 6, SDG 7, and others [24; 25; 26; 27; 28] found in the literature. We can also find review studies for some specified issues or fields while considering the SDGs' properties of integration and indivisibility. [PERSON] et al. selected 70 peer-reviewed articles and explored several themes relevant to SDG interactions instead of respective SDGs, including policy changes, conceptualizing inter-SDG interaction, data sources, and methodology [29]. These review studies also accentuated the core concepts of sustainable development and possible research paths. [PERSON] et al. went through an in-depth content analysis of SDG-related documents, claiming that researchers should consider people, planet, prosperity, partnership, dignity, and justice as the crucial elements in relevant studies to fit them into the interrelationships of the SDGs as discussed and designed [30], which were endorsed by other studies for human rights and SDGs [31; 32]. The roles of central and local governments and NGOs in promoting and implementing SDGs were also explored via SRL and content analysis [33; 34; 35; 36]. Subjects in the broadened fields of business, health, and education were also on the spotlights of SDG-related review papers [37; 38; 39; 40; 41; 42; 43]. Moreover, research methodologies, approaches, and tools for examining the SDGs and the associated research were also reviewed. Techniques such as geospatial information systems (GIS), remote sensing and multiple criteria decision making (MCDM) [44; 45; 46], conceptual issues such as carrying capacity, social innovation, and corporate social responsibility (CSR) [47; 48; 49], and other comprehensive themes can be found in the literature. As more and more research articles accumulate, bibliometrics or scientometrics can help understand the trends and content of SDG-related research papers and identify the gaps. Some studies were carried out with a general scope of the SDGs without focusing on specific themes [12; 50; 51; 52], while more were conducted with respect to a variety of topics, e.g., general management [53], supply chain [54], entrepreneurship [55], health and well-being [56; 57], suicide mortality rate [58], SARS and COVID-19 [59], biofuel [60], agri-food [61], education [62; 63; 64], and peace-sustainability nexus [65], to name a few. As some systemic studies aiming at examining the progress and applicability of the SDGs were carried out in relatively early years, an updated analysis offering the trends and context of SDG-related articles with more accumulated information would be valuable. Moreover, previous bibliometric studies on SDGs as a general issue focused more on meta-level data analysis instead of the more holistic or integrated research topics. In this study, we planned to employ a comprehensive SRL process with a bibliometric tool, CATAR, to depict a whole picture of how SDGs were studied and incorporated into the research articles in an efficient and inclusive way. Overview and clustering analysis will be carried out with some essential information for mapping and demonstration. Networking is the central idea of our bibliographic analysis, as every peer-reviewed article cites previously published articles. The information presented by this study is expected to help research scholars and practitioners interested in or devoted to sustainable development and the SDGs monitor, gather, check, analyze, and use the growing volume of related articles in the literature.
