Implications of urban farming on urban resilience in Indonesia: Systematic literature review and research identification

Abstract This systematic literature review study aims to identify, review, and study the trend of scientific publications on urban farming in realizing the resilience of developing cities in Indonesia. The urban farming trend in Indonesia is a response to overcoming the problem of food security in urban areas as well as a solution to boosting the economy during the crisis due to COVID-19 and creating urban resilience. It will also explore the issue of urban farming as a supplier of projected food availability and food security in urban areas in Indonesia. This research provides scientific guidelines and recommendations for developing urban agriculture studies in Indonesia. This research can be used as scientific data and policy notes on the problem of urban farming in Indonesia. The findings of this study suggest that urban farming will help promote urban resilience in Indonesia, especially given the problems of production, food security, and land scarcity in urban areas. Urban farming in Indonesia’s urban resilience design has several weaknesses even though it has positive effects.


Introduction
Every human being, even every living thing, must have basic needs, including the need for food (Vinayak, 2022).Various ways for humans to be able to meet their food needs either directly or indirectly (Trivellone et al., 2022).Humans can directly grow crops, raise livestock and catch fish and other marine products (Willer et al., 2022).Indirectly, by seeking access to food needs such as the market for agricultural products (in general) to meet these basic needs (Trivellone et al., 2022;Willer et al., 2022).Such importance of food to man is recognized by the state that food affairs are mandatory affairs so that creatures can continue to live.A country's food security will be one of the indicators of the sovereignty of the country itself (Elfida, 20 20;Sastraatmadja, 2022;Trivellone et al., 2022;Willer et al., 2022).
Currently, urban resilience is a concern in many parts of the world, where urban resilience is defined as the endurance of urban ecosystems in facing threats and disturbances on social, economic, and ecological dimensions in the future (Prianto & Abdillah, 2023;Widianingsih et al., 2023).According to Langemeyer et al. (2021) and Gulyas and Edmondson (2021) said that one of the problems of vulnerability in urban areas is how food security meets food needs in urban areas.This is an urban challenge to meet food adequacy to support urban resilience through urban farming (Gulyas & Edmondson, 2021;Langemeyer et al., 2021).Various studies have shown that the influence of urban farming can be a way to create urban resilience in facing future vulnerabilities and threats (Ferreira et al., 2018;Grochulska-Salak et al., 2021;Gulyas & Edmondson, 2021;Langemeyer et al., 2021).Nur,K. W. (202) said In Makassar City, Indonesia revitalized urban alleys to encourage the implementation of urban farming in the Makassar spatial plan as urban land use and positive urban reciprocal interaction.In research by Suparwoko and Taufani (2017) also to face the threat of food security in Indonesia's big cities with rapid physical development and a lack of green land, the government is pushing for the implementation of urban farming.This is why this research is important in understanding practical and theoretical developments regarding urban farming in Indonesia.
The essence of realizing urban resilience is one of the best steps, namely starting with realizing food security itself first (Liu et al., 2022;Yan et al., 2022).To realize urban life, first of all, ensure that the people in it live properly with sufficient food available (Russo & Escobedo, 2022).The phenomena make the development of food security in Indonesia, more it gets noticed day by day.This attention was realized by the Indonesian government by issuing Government Regulation (PP) no.68 of 2002 concerning Food Security, Food Security is a condition for the fulfillment of food for households which is reflected in the availability of sufficient food, both in quantity and quality, safe, equitable, and affordable.In addition, there is Presidential Regulation No. 66 of 2021 concerning the National Food Agency.After nine years of waiting for the end of the mandate of Law No. 18 of 2012 concerning Food, which requests that the Government establish food institutions at the national level (Elfida, 2020;Newman et al., 2022;Sastraatmadja, 2022).Recognizing the lack of food security in Indonesia, based on the national policy on food security, efforts have been made to develop urban agriculture in various regions in Indonesia.
Various urban farming programs in various regions of Indonesia are intended to realize food security and support economic growth in Indonesia to create urban resilience to face future vulnerabilities (Qurani et al., 2020;Aditya and Zakiah, 2022;Elfida, 2020;Ferdaus, 2022;Kementan, 2022;Malik et al., 2021;Sastraatmadja, 2022;Atmaja et al., 2020).This urban farming developed in response to the many problems related to urban life.Namely, the decreasing agricultural land due to development, the increase in food demand in urban areas, environmental pollution due to pollutants, and the economic crisis due to COVID-19 (Kementan, 2022;Ferdaus, 2022;Wibowo et al., 2021;Silitonga et al., 2022;Suantika, 2018;Wunarlan et al., 2023).This triggers people with the ability and knowledge in agriculture to take advantage of opportunities by optimizing the potential of surrounding resources.The goal is to cultivate vegetable crops on limited and abandoned land optimally as Urban Farming (Elfida, 2020;Ferdaus, 2022;Kementan, 2022;Sastraatmadja, 2022).
The urban farming trend, if it continues to be developed and is projected to be a supplier for food availability and food security in urban areas (Darmawan et al., 2023;Elfida, 2020;Ferdaus, 2022;Kementan, 2022;Sastraatmadja, 2022).The ability to meet food needs independently will reduce the obstacles to food distribution in urban areas (Hardiana and Hutasuhut, 2021;Gusfarina et al., 2021;Elfida, 2020;Ferdaus, 2022;Kementan, 2022;Sastraatmadja, 2022).As a lifestyle, the urban farming trend is considered a healthy lifestyle.This is because most urban farms prefer to implement an organic planting system that does not use chemical fertilizers and synthetic pesticides.Urban farming can create a comfortable and healthy environment to live in with various planting systems such as viticulture, hydroponics, and aquaponics that can easily be applied in limited areas (Prayoga et al., 2020;Novira et al., 2019;Elfida, 2020;Ferdaus, 2022;Kementan, 2022;Sastraatmadja, 2022).This research is intended to look at these trends, identify developing issues, as well as look at the relationship between studies and problems regarding urban farming in Indonesia.

Objectives
This study aims to investigate the trend of urban farming in Indonesia in terms of current data sharing and factors related to it in terms of journals published in the Scopus database.The analysis is based on data from 106 documents with the keywords "Urban Farming" and "Indonesia" in the Scopus Database.Research questions include: To what extent are the trends in scientific publications studying urban farming in Indonesia?who are the researchers contributing to scientific publications on the topic?what are the latest research issues/topics related to the issue of Urban Farming in Indonesia?And an assessment based on 32 articles on this topic reveals much exploratory, conceptual, qualitative, and practice-driven research in studies reflecting the increasing complexities of urban farming-urban resilience and the resulting implications, opportunities, and risks thereof for urban resilience.

Ethics statement
Neither approval by the institutional review board nor obtainment of the informed consent was required since this was a literature-based study.

Study design
This was a descriptive study based on journals' policies.This study uses the systematic literature review analysis method with data sources from literature studies from various scientific journals.The primary data used in this research was taken from the Scopus database.The author chose the Scopus database because it has complete data and is also one of the databases with the highest rating in various scientific fields.And they are also equipped with various literature studies to improve research accuracy and get the best conclusions.To produce relevant discussions and conclusions, the authors use the VOSiewer analysis tool version 1.6.17as a suitable data processing tool (tools for identification and analysis) from the Scopus Database (Abdillah et al., 2022;Bano & Zowghi, 2015;Batini et al., 2009).Other analysis tools also use "analyze search results" on scopus.com.

Data collection methods
A total of 102 documents accessed in 1 January 2023 include urban farming in Indonesia, a total of 40 documents mapped and analyzed following the trend of research publication data search results in Scopus.Any data or goods displayed based on search results, and filtered through scopus.com(in the "analyze search results" feature), are then identified and analyzed using the VOSviewer version 1.6.17feature to be visualization (Abdillah et al., 2022;Van Eck & Waltman, 2010).The visualized data follows the calculated weights and also looks at the trends of the existing data based on the data obtained.It also influenced the study not to display data visualizations on other less relevant items.Results from identification and exploration based on 3 criteria relevant si with the topic of Urban Farming in Indonesia which refers to (1) Suitability with the research topic; (2) Connectedness to the topic of research; and (3) Research implications found or recommended (Bano & Zowghi, 2015;Batini et al., 2009).
At this stage, each abstract is checked independently by at least two authors.Minor differences of opinion were discussed and resolved in meetings where the agreement was reached.According to the above criteria, 8 studies were deleted, and 98 studies remained retrieved from 2004-2022.Second, the relevance and quality of the 98 studies were assessed by reading the full articles.Then 40 studies were feasibility-reviewed and independently assessed according to independentdimensional quality criteria from Batini et al. (2009) and Bano and Zowghi (2015), with several criteria: • Accuracy: research objectives are clearly stated, and data collection methods are adequately explained.References support important statements in the paper.
• Consistency: research design according to research objectives.Research questions answered or research objectives achieved.
• Completeness: the study's research approach is explained in sufficient detail.
This led to the final selection of 32 research studies from 2004-2022 that directly address the question of the development of urban farming in Indonesia (see Figure 1).In accordance with our inclusion and exclusion criteria, the limited number of studies remaining, despite our extensive search of the relevant literature, is a finding in itself.This small number highlights the dearth of research examining the topic of urban farming in urban resilience strategies in Indonesia.))" that is in the Scopus Database.All search result data is stored in a CSV (Excel) file which is then processed and checked using the VOSiewer program version 1.6.17.VOSviewer is a tool for displaying and analyzing trends in systematic literature review maps (Van Eck & Waltman, 2010).The program can display and depict bibliometric visual maps with unique data through identification and analysis of the types of analysis that can be visualized in Vosviewer, as Figure 2 follows:

Data analysis
This systematic literature review analysis approach is used to help provide a data set that can be utilized by policy-makers, academics, and other stakeholders to improve the quality of future research (Abdillah et al., 2022;DiVaio et al., 2022;Wang et al., 2021).The systematic literature review method is also a comprehensive and reliable way of reviewing and evaluating scientific publications to understand the development of certain research topics (Moral-Muñoz et al., 2020;Wagner et al., 2011).The analysis of this research is also to see how the influence of urban combat can be a way to create muscle resilience in facing future vulnerabilities and threats.

Mapping of research topics: An overview
In mapping research topics and reviewing in this study, as early as 102 documents were identified and analyzed through the links scopus.com(Analyze search results) and Vosviewer (Van Eck & Waltman, 2010) to find out and see trends in research publications on the topic of urban farming in Indonesia in the Scopus database.The results show a trend of increasing each year even though the increase is still dynamic.This increase was influenced by developing issues such as urban food scarcity, expansion of urban land and arrangement of agricultural land, natural disasters, environmental issues, and so on.This trend can be seen in Figure 3 below: The tendency to increase the number of publications comes from collaborative studies of various countries in the world in studying urban farming and urban resilience in Indonesia.The trend of increasing every year is influenced by several things such as the interest of researchers regarding urban farming and urban resilience in Indonesia, research funding support, and access to available research data.Then 2021 is the year with the highest number of publications in the last ten years in the Scopus database.In Figure 4 there are the top 10 countries of origin of various authors who study and publish several scientific documents regarding the study of urban farming in Indonesia, such as (1) Indonesia with 33 documents (173 citations); (2) Netherlands with 3 documents (28 citations); (3) Japan with 3 documents (49 citations); (4) Germany with 2 documents (2 citations); (5) United States with 2 documents (2 citations); (6) France with 1 document (4 citations); ( 7) China with 1 document (10 citations); (8) Malaysia with 1 document (34 citations); ( 9) Singapore with 1 document (13 citations); and (10) Taiwan with 1 number of documents (0 citations).It can be concluded that the author's country of origin is Indonesia with 32 documents, followed by the Netherlands and Japan with 3 documents each.This indicates that the topic of Urban Farming which supports urban resilience in Indonesia has been studied by various countries around the world.This was because (1) various researchers in Indonesia and the Netherlands wanted to understand the relationship between urban farming and urban socio-economic systems; (2) several researchers in Japan also understand the ecological landscape and urban biodiversity in Indonesia's tropical cities; (3) not much different from researchers from Singapore who wish to understand the relationship between urban farming, food security, and development policies in Indonesia.And (4) the issue of environmental pollution and poverty reduction is another reason for researchers from various countries in the world to be interested in studying urban farming and urban resilience in Indonesia.
In addition to the country of origin of the author who studies and publishes various scientific documents regarding the issue of Urban Farming in Indonesia.In Figure 5, the published study document has various types of documents, such as (1) Articles with a total of 57 documents; (2) Conference Paper with 32 documents; (3) Revision Conference with 5 documents; (4) Review with 5 documents; (5) Book Chapter with 1 document; (6) Erratum with 1 document; and (6) Short Survey with 1 document.It can be concluded that the variety of types of documents regarding urban farming studies in Indonesia makes this issue one of the concerns for researchers in the world, this is shown by 6 types of published documents discussing urban farming in Indonesia in the Scopus database.
Various types of documents were published in the Scopus database regarding urban farming in Indonesia.Figure 6   various subject areas, these are the top 10 subject areas with the most number of documents.This indicates that the issue of urban farming studies in Indonesia is studied through various perspectives, approaches, and variants of scientific disciplines.So that to be able to understand the study of urban farming issues cannot only be seen as environmental problems, social problems, energy problems, economic and health problems but needs to be studied from various sciences so that the problems that exist in urban farming in Indonesia can be overcome.The systematic literature review in this study shows that research on the problem of Urban Farming in Indonesia is an urban agricultural problem that continues to be developed and is projected to be a supplier for the availability of foodstuffs and food security in urban areas in Indonesia.Trends regarding this study have been seen since 2004 continuing to increase until 2022 which is published in the database Scopus.The issue about the study of urban farming in Indonesia has been studied through various perspectives, approaches, and variants of scientific disciplines.And there are various types of documents documenting urban farming studies in

Mapping of research topics: Content analysis & issues
Below are identified various research topics that are closely related to Urban Farming in Indonesia based on various documents that have been published in the Scopus Database.It was found that the research issues related to this research topic are shown in Figure 8 (explain the grouping of research issues that are most related to one another): In the review through Vosviewer in Figure 8 as many as 32 research documents were derived from the Scopus database.The results found that five (5) clusters have become a trend ds research topic on urban farming which until now has become the focus of global researchers and has become a serious study in Indonesia.The 5 clusters are divided into, The first cluster (red), Its tendency focuses on ISS Agricultural Activities, Agricultural Robots, Farming Activities, Land Use, Population Statistics, Sustainable Development, Urban Environments, and Urban Planning; The second cluster (green), is more likely to learn about farming systems, local participation, study the phenomenon of agricultural problems in South Sulawesi, urban farming, and urban development; The third cluster (blue), is more likely to study the problems regarding food security in East Java, Jakarta, and Food Security in urban areas due to urbanization; The fourth cluster (yellow), is more likely to learn about urban agricultural problems during the COVID-19 pandemic; and The fifth cluster (purple), is more likely to learn about the agricultural sector about the supply of food and food in rural areas.In each cluster is the main issue of research on urban farming that has been widely studied and published in the Scopus database.The research topic can build future researchers in developing topics regarding urban farming problems in Indonesia.So that this research contributes practically and theoretically to developing a diversity of literature on the problem of urban farming in Indonesia.This research issue, can also be research data looking at global research trends regarding what has been, has not been, and will be studied further on the topic of urban farming in Indonesia.
Not much different from what is shown in Figure 9 above (explain the novelty of the research topic).The results of the visualization (Overlay Visualization) show that there are several trends in the latest research (shown in the picture with the brightest color "yellow") from 2018 until 2020 Several research trend issues explored regarding urban farming in realizing urban resilience in Indonesia, it is still lacking and there is still little research on the study about that.The results of this identification and analysis are intended to support existing studies and encourage studies on urban farming in realizing urban resilience in Indonesia and in various countries around the world.The researcher concludes that Indonesian researchers can develop the issue of urban farming research in realizing urban resilience based on these four important issues.

Implications of urban farming in supporting urban resilience in Indonesia: A challenge and opportunity for Indonesia
In this section, we discuss the implications of Urban Farming in supporting urban resilience in Indonesia, as identified from the articles in our sample.We identify challenges that we categorize into 4 categories: (1) Urban Farming as a Strength in Urban Resilience, (2) Weaknesses of Urban Farming in Urban Resilience, (3) Threats from Urban Farming in Urban Resilience in Indonesia and (4) Urban Farming as an Opportunity in Urban Resilience in Indonesia (see Table 1).
In this study, the trend of previous research (in a systematic literature review that we have made) regarding Urban Farming towards Urban Resilience has several opportunities based on relevant studies that have been published.The researchers divided it into 4 categories, namely: (1) This tendency can be seen in the lack of (potential) Urban Farming in encouraging urban resilience in Indonesia through suburban farming and individual farmers in urban communities in Metropolitan Areas in Indonesia (Ridwan et al., 2017;Adiprasetyo et al., 2015;Pribadi & Pauleit, 2016), policy support (Arifin & Nakagoshi, 2011), Urban Farming as a solution to the vulnerability of urban communities in Indonesia (Nur, 2020;Surya et al., 2020), Urban Farming as an agricultural solution facing the problem of limited land in urban areas in Indonesia (Rijanta, 2015;Chandra & Diehl, 2019;Taufani & Taufani, 2017); (2) Weaknesses in Urban Farming to realize Urban Resilience in Indonesia, such as urbanization & dense population making it difficult to use the land for urban farming, the thing that most affects food security in Indonesia is land ownership for farmers (Mutiara et al., 2020;Wisnubroto et al., 2021), much land is controlled by the private sector (Pratama et al., 2021); (3) Threats faced by Urban Farming towards Urban Resilience, such as the problem of plastic waste (Wibowo et al., 2021;Yossyafra et al., 2018), and the dilemma of young farmers in urban farming (Safitri et al., 2021;Safitri et al., 2022;Setiawan et al., 2019); and (4) Opportunities in encouraging urban resilience through Urban Farming in Indonesia, developing a Hybrid Zero Water Discharge (ZWD) to improve water quality in boosting productivity in Urban Farming (Suantika et al., 2018;Ulfa et al., 2022), there is an intensification of the dominant cultivation strategy implemented by farmers in urban farming in Indonesia (Titisari et al., 2022;Hatanaka, 2015;Syaifudin & Carsjens, 2018), the role of female farmers in Urban Farming (Yulida et al., 2018).Some of these studies represent research identification tendencies that have been published in studying the issue of Urban Farming for Urban Resilience in Indonesia.
According to the research's conclusions, urban farming will help Indonesia's cities become more resilient, particularly in light of issues with production, food security, and urban land scarcity.Urban farming in Indonesia's urban resilience design has several drawbacks despite its positive effects.Accordingly, this study suggests that the Indonesian government create a green policy that focuses on the growth of urban farming in a variety of Indonesian regions.In order to address the community's economic vulnerability, which has an impact on the region's urban resilience, the policy must be flexible and in line with the demands and circumstances of urban regions.

Conclusion
Trends related to this study have been recorded since 2004 and continue to increase until 2022, 32 documents that match the topics studied in this study are obtained, according to a publication in the database Scopus.The topic of urban farming and urban resilience in Indonesia has been studied from various perspectives, methodologies, and scientific disciplines.Various types of research papers on urban farming in Indonesia have been published in the Scopus database (at least 6 fields of study have been identified).The top 10 authors who published their document are (1) Pribadi and Pauleit (2016)   interested in learning about urban farming in realizing urban resilience in Indonesia, such as (1) the Netherlands; (2) Japan; (3) Singapore); (4) Germany, and many more.
Research topics on urban farming in Indonesia can help future researchers in understanding the problems of urban farming in Indonesia.So that this research contributes practically and theoretically to developing a diversity of literature on the problem of urban farming in Indonesia.This research issue can also be research data looking at the trend of global research is what has been, has not been, and will be studied further on the topic of urban farming in Indonesia.The researcher recommends that future researchers focus on: (1) How is the best model of urban farming in realizing urban resilience; (2) How to develop urban resilience in urban farming; (2) How is the use of limited land for urban farming; (3) how to promote urban farming to increase local participation in urban farming activities; and ( 4) what is the post-pandemic impact of COVID-19 on urban food security.
The implication of this research is that urban farming will help in encouraging urban resilience in Indonesia, especially in the problems of production and food security, to the problem of limited land in urban areas.Even though it has a good impact, Urban Farming in designing urban resilience in Indonesia still has limitations.So based on this, this research recommends the Indonesian government formulate a green policy that focuses on the development of Urban Farming in various regions in Indonesia.These policies must be adaptive and in accordance with the needs and conditions of urban areas in facing the economic vulnerabilities of the community which have an impact on urban resilience in these areas.
