“…This also allows researchers to retain the traditional units of recording, while simultaneously broadening the perspective by including information about the relationships across these units. This additional structural information allows researchers to address existing research questions using new tools, approaching them from a different theoretical perspective (Benites-Lazaro et al 2018b). Second, discourse analysis (DA), which consists of a set of techniques for the structured research of texts.…”

“…It is "the study of language-in-use and is employed to engender a range of meanings varying from the analysis of linguistic regularities to the normative quality of discussions" (Benites-Lazaro et al 2018b, p. 320). Similar to Benites-Lazaro et al (2018b) in this study, we used a mixed-method for the DA, in order to take advantage of both qualitative and quantitative techniques. It assumes that, both, the number of word repetitions performed by software and the exploratory lexical patterns, play important roles in textual analysis.…”

In the last decade, the debate on the governance of water, energy, and food (WEF) has intensified, spurring the emergence of the term "nexus governance." In general, the reduction of trade-offs and construction of synergies between WEF have been placed on the scientific, political, and economic agenda. However, although increasingly used, it is difficult to find a clear meaning and definition of what the term represents. Based on a systematic literature review (SLR), using text-mining and machine learning algorithms, this article investigates what are the conceptual basis of the nexus governance debate, and attempts to clarify the main themes, networks, and gaps within this literature. The analysis is based on quantitative and qualitative methods, combining social network analysis (SNA) and discourse analysis (DA). The results highlighted that twenty-four governance-related concepts support this literature, breaking down into eight groups: water and basin governance; environmental and systems governance; risk and resource security governance; economic governance; global governance; urban governance; integrative and cooperative governance; and "epistemic" and transdisciplinary governance.

“…Undoubtedly, energy use is strongly related to almost all aspects of development, including income, health, nutrition, water, infrastructure, education, and life expectancy. However, energy production and consumption are associated with an increase in the global inequalities and environment deterioration too.The latter is a result of the use of fossil fuels from mostly industrial, agricultural, commercial, and residential systems that were built based on "black gold" (BENITES-LAZARO et al, 2018a;URRY, 2010). At present, the production and consumption of energy is the largest source of global GHG emissions (BALAT, 2005;BAZILIAN et al, 2014;REHMAN;RASHID, 2017).…”

This paper analyzes the historical trends in the energy supply and demand for the Macrometrópole Paulista Energy System, as well as the existing options for harnessing the renewable energy potential of the region. The research included a case study covering the 174 municipalities that belong to the macro-metropolis to characterize the energy system from 2006 to 2017 while analyzing the CO2 emissions of the system. The results indicated that, in 2017, the Paulista macro-metropolis accounted for 73% of the total energy demand of the entire state of São Paulo. Moreover, considering the energy generated from within the administrative limits of the 174 municipalities, the macro-metropolis accounted for about 17% of the total installed capacity of the state for electricity generation. This study found that the installed capacity for electricity generation in the region can be increased by ~ 112%. There so, an understanding of the local energy systems is of utmost importance for the formulation of coherent and integrated public policies, which are necessary to cope with the effects of climate change.

A Literature Review to Propose a Systematic Procedure to Develop “Nexus Thinking” Considering the Water–Energy–Food Nexus

et al. 2019

There is a growing interest in the literature on the theme of the water–energy–food nexus, as there is growing recognition that sectors that share natural resources have interdependent and interconnected systems. Despite the widespread popularity of nexus thinking, it still lacks standardized procedures and methodologies to assist in its development. Therefore, this paper proposes, from a literature review, a systematic procedure to assist in the development of management models based on nexus thinking. To this end, 304 papers were analyzed using the following criteria: nexus concept, type of approach, geographic scale, elements in the nexus system, application context, and types of assessment methods and tools. The results of the review served as the basis for determining the procedure, which consisted of four steps: (a) understanding nexus thinking, (b) identification of composing variables, (c) evaluation (diagnosis and prognosis), and (d) decision-making. In addition to the standardization of these steps, the main information used to compose the procedure was organized and synthesized with a mind map.
