The use of the Bibliometrix package of the R software makes it possible to collect data and relevant information about the articles obtained in the research. In this sense, graph 1, prepared through Biblioshiny, presents the annual scientific production rates on the researched topic. Note that the X axis represents the time interval in which there were publications, while the Y axis presents the volume of articles produced per year.

Annual scientific production
Scientific production on participatory budgeting and climate change began in 2009, and as the graph shows, the trend has continued to grow over the years, with an average growth rate of 7.3%. However, in the years 2011, 2015 and 2020 there are percentages of decline in production, while the peak of academic production took place in 2021, with a total of 54 articles.
In addition to the annual production, through citation analysis, it is possible to observe the impact of journals, groups of scientists and articles. Among all the journals analyzed, it was noted that Sustainability has the highest number of publications, with a total of 17 articles, being respectively the journal that has the highest H-index, an index that measures the impact and productivity of journals (see Table 4). On the other hand, out of a total of 144 journals analyzed, 83.3% (120) have only one article published on the subject.

Journal of the American Planning Association | 3 | 1 |
Sustainable Development | 3 | 2 |
Ambio | 2 | 2 |
Climatic Change | 2 | 2 |

Furthermore, it is crucial to observe the scope of the journals that most published articles related to participatory budgeting and climate change. The vast majority are focused on sustainability and sustainable development, as is the case with Sustainability, Ambio and Sustainable Development; or even urban planning, such as the International Journal of Urban and Regional Research, Cities, Environment and Urbanization. There is still one case in particular, whose scope is the production of research related to climate change, namely the Climatic Change journal.

Likewise, it is essential to highlight the most cited articles in the Scopus database, being the study carried out by Vanessa Watson (2009), The panned city sweeps the poor away: Urban planning and 21st century urbanization, which since its publication has been cited 315 times, an average of 22.5 citations per year. An interesting aspect is that the article does not specifically refer to the central theme of the research, although it addresses each of the themes, it does not address the correlation between them. It should also be noted that only two of the most cited articles were published in the journals that produce the most: A review of the main challenges to urban sustainability (Ramin, 2010) and Inclusive urbanization: Can the 2030 Agenda be delivered without it? (McGranahan, 2016), as seen in Table 5.

Table 5: Most cited articles
From a different perspective, Fig. 1 presents the authors who published the most studies on the subject under analysis. The X axis corresponds to the years in which each study was published, while the Y axis corresponds to its authors. In the figure, it is possible to observe the existence of circles that represent the quorum of published articles, which means that the larger the circle, the more publications the author has. It is also noted the existence of lines that connect the circles and represent the constancy of publication of the articles, that is, the more constant the line, the more solid is the quantity of publications by the author. In this vein, both the frequency and the number of published articles can be seen in Fig. 1.
It can be seen from the observation in Fig. 1 that research in the scope of participatory budgeting and climate change is quite sporadic, because only two authors, London and Satterthwaite, maintained publications for a longer period. Still in this context, it is notable that only in the year 2021, the number of publications was high, while in other years, publications are scarce.
In turn, with regard to the comparison between the publication and citation indices by countries, it can be seen in Table 6 that, in a way, there is a proportionality relationship between the country with the most publications and the most citations. However, this proportionality only materializes in the first two countries, because the United Kingdom is the country with the highest number of publications (31), and is also the country whose authors are most cited (518), the United States has the second largest number of articles (31), and consequently the second largest number of authors cited (479). In the other cases, there is no proportionality relationship, since the countries that produce the most do not have the largest number of authors cited. This is what happens with Canada (8), which despite having a higher number of articles than China (5), is below this in terms of the number of authors cited (Canada – 71; China – 75).

Besides, to using Biblioshiny from the Bibliometrix package, another bibliometric analysis software was also used, namely VOSviewer, as mentioned. This tool allows the creation of bibliometric maps, which constitute a graphical representation of correlations between the articles under analysis (Van Eck & Waltman, 2010). The construction of maps in this software uses the VOS mapping technique, which translates into a visualization of the similarities between the documents (Van Eck & Waltman, 2010). The purpose of graphical construction of maps is to make the interpretation of information easier and more practical (Van Eck & Waltman, 2010).
The maps represented in the study – Figs. 2 and 3 – are representations of co-citation and co-occurrence networks, respectively. It is important to note that in the graphical representation circles connected by lines are observed, with the former representing the items, while the latter represent the connections between the items. Meanwhile, the larger the circle, the more relevant the corresponding item and the more times it was repeated in the articles, and the denser the line, the stronger the connection between them (Campigotto-Sandri et al., 2020).
The map represented in Fig. 3 constitutes a network of co-citations, of the authors that were most often cited in articles, that is, the most relevant authors. For the creation of the map, only authors who have been cited 20 or more times were selected, resulting in the selection of 38 studies, divided into five groups or clusters, identified by colors.
In group 1, represented by the color yellow, the studies carried out by Takayuki Ito (2014) and Alex Karner (2013) are the most relevant, having been cited 40 and 27 times respectively. Furthermore, based on the observation of the most cited studies, it is noted that the central theme of the group is the participation of citizens. In turn, group 2 corresponding to the color blue, has as its central axis studies on the Participatory Budget, with the most cited articles by Gianpaolo Baiocchi (2005), with 38 citations, and Elinor Ostrom (2003), with 37 citations.
The third group, demarcated by the color red, deals mainly with climate change, more precisely in the context of mitigation, adaptation and urban planning. The most relevant works in the cluster are those by Harriet Bulkeley (2007) and David Satterthwaite (2020), with 37 and 35 citations respectively. Group 4, represented by the color green, is related to citizenship, participatory communication and also participatory processes. An interesting factor is that the most cited authors among all belong to this group, namely Archon Fung (2001), cited 72 times, followed by John S. Dryzek (2009), with 46 citations.
Finally, group 5 in the figure, represented by the color purple, is characterized by having the lowest number of cited works. The most relevant authors of the group are Jürguem Habermas (1989) and Judy Brown (2009), both with 30 citations, and their works have as their central theme the participation of citizens in public finances, as well as deliberative engagement in public decision-making. (See Fig. 2).

Considering that the objective of the study is to evaluate the academic production on participatory budgeting and climate change together, it is also crucial to carry out a textual analysis of the articles, more precisely on the most common keywords used by the authors. In the foreground, through Biblioshiny, it was possible to obtain a graph that presents the ten most frequent keywords in the articles, as seen in graph 2. This is one of the ways to identify the central themes of the articles researched, and to verify if in fact, participatory budgeting and climate change are objects of research.
Graphic 2
Most common keywords by Authors
From the analysis of the 194 articles that make up the research quorum, it was found that the keyword most used by the authors is Governance, used 14 times throughout the texts. Although the search terms were Participatory Budget/Budgeting and Climate change, these are not the ones that occupy the main position in the articles, with climate change being used as a keyword 13 times and participatory budgeting only 9 times.
Corroborating the graph, it was decided to create a bibliometric map in the VOSviewer software, which enabled the graphical representation of the information, dividing the terms into groups. It is crucial to highlight that the authors' keywords were also considered, with a total of 751 terms. To define which ones would be represented on the map, we chose to use the co-occurrence of terms, that is, words that appeared together in the articles, requiring at least five co-occurrences. Thus, the result was a map with 18 co-occurring terms, subdivided into five groups.
The same characteristics apply to the case, that is, the larger the circle, the more times the term was cited. The lines represent the correlations between them, that is, the denser the line, the more times the terms appear together. And the color groups represent the thematic connections. It is noted that similarly to what was shown in graph 2, the terms governance and climate change appear as the most cited, while participatory budgeting does not have the same prominence (see Fig. 3).
Bearing in mind the expectation that participatory budgeting and climate change had been worked out together, there is an inexorable disappointment in the observation of the bibliometric map, this because the fields do not appear correlated. It can be seen that climate change, a term present in cluster 5 (red), appears related to urban planning and local governments, but not to democratic participation. From another perspective, participatory budgeting, despite not being directly related to climate change, appears connected to sustainability and sustainable development.
The other groups, despite not being directly connected to climate change and participatory budgeting, are indirectly connected by addressing citizen participation and engagement, participatory democracy and sustainable development goals.
4.1 Discussion of results
The bibliometric analysis of the academic literature on the correlation between participatory budgeting and climate change resulted in a dichotomy. On the one hand, it was possible to obtain a reasonable number of articles (194), published in important journals and by respected authors. However, on the other hand, in practical reality, such articles do not actually correspond to the objective of the research, because, for the most part, they are related to other themes.
In the foreground, and having as a parameter the annual production rate, there seems to be a positive balance, given that the trend of production of studies in this area is increasing. However, when looked at more deeply, the articles that served as the basis for the analysis generally have more comprehensive approaches, such as citizen participation, participatory democracy, participatory governance, sustainability and sustainable development.
Note, for example, in the list of the most cited articles, there is none that specifically refers to participatory budgeting and climate change. Although the themes may eventually be addressed, they are always in different fields of studies, not correlated. The same occurs when considering the authors most cited in the references, since their works also do not address the themes together at any time. Even within the scope of keywords, it is possible to notice this lack of correlation, in addition to the fact that the participatory budget does not even play a leading role among the researches, being rarely mentioned.
Among all the articles analyzed, only two specifically address participatory budgeting related to climate change: Can participatory emissions budgeting help local authorities to face climate change? by Tom Cohen (2012), and Contributions of participatory budgeting to climate change adaptation and mitigation: current local practices across the world and lessons from the field, by Yves Cabannes (2021). The first case is more restrictive, since the article aims to expose the existence of a participatory budget project aimed at the emission of greenhouse gases, carried out by the local authorities of the United Kingdom. On the other hand, the second article is more comprehensive, since it evaluates 15 cases of Participatory Budgeting for Climate Change around the world, demonstrating the relevance of carrying out more studies on the themes
Final considerations and future research perspectives
The bibliometric analysis of the literature showed that studies on participatory budgeting correlated with climate change are still in an embryonic state. In fact, only two of all the articles observed addressed the themes together, while the others had different themes. It was noted that there is a gap in the academic literature, which needs to be filled, considering that both climate change and participatory budgeting are emerging research topics.
In view of this, for future research it is essential that there is a dedication to: i) analyzing cases of (in) success around the world; ii) understand why some municipalities apply these projects and others do not; iii) verify that the participatory budgeting projects to mitigate the effects of climate change have achieved the expected result; iv) to study the role of state / regional / local power in the implementation of participatory budgeting processes for climate change, v) to analyze whether the behavior of citizens is transformed by participation in projects of this kind, both from an environmental and a democratic perspective. In effect, the maximum objective of the participatory budgeting is to give citizens the possibility of transforming their social environment, through the strengthening of Democracy, so using it also as a means of transforming the climate change scenario, can be an excellent initiative.
