Round 1

Reviewer 1 Report

Comments to the authors:

The present study describes the sustainability pillars for food production in order to improve the sustainable food production and food security. The authors have proposed five sustainability pillars, however, which is not focused and well defined. It needs to be presented in a better manner to understand it. The pillars are written in general state, which is not written in depth to make the audience aware about it. In my opinion, ‘technology’ is a part of economic pillar, while ‘culture’ is a part of social pillar of the sustainability. Thus, both are connected with the environment pillar of the sustainability.

The manuscript has many errors, in many places it is hard to understand due to poor language, long sentences and lacks in connectivity (synchronization). Hence, there is a scope to improve the quality of the Ms to make it readable to a wide range of audience. The Ms lack the coherence in the text and lacks in the connectivity of the proposed sustainability pillars.

The conclusion section needs to be reduced. The conclusion and discussion section needs to be written precisely. I regret to inform you that I cannot accept the article in its current form.

Specific comments:

Title- The title of the article needs to be updated.

Abstract- The abstract portion needs to be re-written.

Introduction- The introduction section needs to be improved because this portion is not focused.

Results- The results section needs to be improved with a coherence and connectivity.

Discussion- The discussion part is not written well, which needs to be written well to describe the connectivity and importance of the study.

Conclusion- This part also need to improve.

Reference- Too much references.

I have also given the comments in the annotated document, so check it out and address it correctly.

* The present study describes the sustainability pillars for food production in order to improve the sustainable food production and food security. The authors have proposed five sustainability pillars, however, which is not focused and well defined. It needs to be presented in a better manner to understand it. The pillars are written in general state, which is not written in depth to make the audience aware about it. In my opinion, ‘technology’ is a part of economic pillar, while ‘culture’ is a part of social pillar of the sustainability. Thus, both are connected with the environment pillar of the sustainability.

Thank you very much for the comments.

During our research we detected that a variety of food production systems are declared to be sustainable, but without an explanation why they are considered to be sustainable. Therefore, we analyzed the traditional dimensions of sustainability; economic, social and environmental. Food production is based on technology and on innovation which could be considered as an economic factor, but the past has shown us that not all food production system based on high technology are sustainable, for example, a lot of the technologies implemented during the green revolution are not sustainable. Therefore, we implemented the technological pillar of sustainability and separated from the economic pillar to show that there can be sustainable technology in food production, but maybe it is not as profitable as monoculture food production systems. Moreover, food production is based on cultural heritage and practices which were implemented centuries ago. Social sustainability is based on the educational impact of food production and the well being a farmer could gain by using sustainable production methods. Social sustainability does not reflect the cultural aspect of a regional food production system, the use of regional grains and regional adapted production systems. Therefore, we think it is really important to separate social and cultural sustainability to analyze different food production systems, because, due to the green revolution, a lot of farmers use imported technology and production knowledge instead of local adapted production systems.

 

* The manuscript has many errors, in many places it is hard to understand due to poor language, long sentences and lacks in connectivity (synchronization). Hence, there is a scope to improve the quality of the Ms to make it readable to a wide range of audience. The Ms lack the coherence in the text and lacks in the connectivity of the proposed sustainability pillars.

We have evaluated the situation of the English quality of our article and we have decided to send the article for further revision to native English speakers so that we can have a better English quality of our manuscript. Moreover, we made it more readable by preediting our content and connecting in a better way the different ideas.

 

* The conclusion section needs to be reduced. The conclusion and discussion section needs to be written precisely.

We think that our conclusion and discussion have an accurate size and gives the reader the context about sustainability in food production. Also, we are discussing and concluding perspectives about sustainable food production.

 

* Title- The title of the article needs to be updated.

We think that the title “A Review of Sustainable pillars and the fulfilment in agriculture, aquaculture and aquaponic production” is accurate, because we are reviewing the traditional pillars of sustainability and adding two new pillars (culture and technology) to our definition. These new pillars are normally not considered and defined in food production system. Nevertheless, in the introduction we are describing the relation between sustainability and food production and giving an explanation of the relation between the food production systems and the sustainability pillars which are considered for this review article.

 

* Abstract- The abstract portion needs to be re-written.

The Abstract has been improved by a native speaker and adjusted to provide a better overview of the content of our article.

 

* Introduction- The introduction section needs to be improved because this portion is not focused.

The introduction is focused on the traditional pillars of sustainability and to understand the importance of culture and technology in food production, so the reader could notice that this two pillars must be analyzed separately.

 

* Results- The results section needs to be improved with a coherence and connectivity.

We based our review on the sustainable pillars that are viable in food production and are connected directly with food production. We think that our results are accurate, because in the first part we present our investigation about the sustainable pillars in food production and in the second part we explain three different systems, why they are sustainable and why not.

 

* Discussion- The discussion part is not written well, which needs to be written well to describe the connectivity and importance of the study.

We treated this topic above and we corrected the English.

 

* Conclusion- This part also need to improve.

We treated this topic above and we corrected the English.

 

* Reference- Too much references.

We made a deep analysis about sustainable pillars, therefore, we needed to review the literature directly with food production systems, but also close related literature, especially in the cause of the cultural and technological pillar. Culture and technology are not often considered to explain sustainability characteristics of food production which required further explanations. Moreover, in the last weeks there were many reviews published in Sustainability with the same number or even more references than our article has.

Reviewer 2

* The authors of the manuscript provided a very broad overview of sustainability pillars/dimensions and potential pillars/dimensions but did not mention any institutional pillar/dimension initiatives analyzed by other researchers (Spangenberg, J. H., Pfahl, S., Deller, K. (1999); Spangenberg, J. H. (2002); ÄŒiegis (2003); Djoghlaf A. (2007); Omar, O., Kamarulazizi, I., Kanayathu, K., Marlinah, M. (2015); Bencardino, M., Nesticò, A., Esposito, V., Valanzano, L. (2022); etc.). If the authors have a different opinion, they can provide arguments or refer to opposing researchers, but this is not even mentioned now.

Thank you very much for your comments.

We know that institutional sustainability is a very important topic, and it can also influence food production systems by the implementation of norms, laws, rules and advices by governments (federal, state, local), universities and ONG´s. In our review article we are concentrating on the sustainability of three food production systems; agriculture, aquaculture and aquaponics and how the production processes are taken out. We did not focus on the political and institutional environment where a food production is taking place, since these vary from region and countries. We concentrated on our experience with small agriculture and aquaculture farmers in rural areas of Mexico and searched for general and specific information to every system studied and analyzed the problems which were reported in scientific research articles.

In addition, we reviewed the authors you mentioned and find their positions interesting, but we think that it requires a deeper analysis of institutional sustainability and future studies related to food production systems and how institutional sustainability could help to implement good production practices to push food production sustainability even further. Therefore, we added a new paragraph to our discussion to show other investigators that there is a lot of potential for future investigation:

Original: “All these considerations could be also applicable for agriculture and aquaculture to estimate the sustainable impact of food production, in general.”

Modified version: “All these considerations could be applicable for agriculture and aquaculture and help to improve the sustainable impact of food production in traditional production systems. In addition, farmers and agricultural regions need help from different institu-tions (governments, universities, and non-profit organizations) to develop new sus-tainable practices based on technology advancements [187]. For example, there is a high potential in using organic fertilizer, waste management [188], and digitalization [189], which could be facilitated by new institutional sustainable strategies.”

Lines 561 to 567

 

* Manuscript title is "A Review of Sustainable pillars… ", so it should be improved a bit.

We think that the title “A Review of Sustainable pillars and the fulfilment in agriculture, aquaculture and aquaponic production” is accurate, because we are reviewing the traditional pillars of sustainability and adding two new pillars in culture and technology to our definition. These new pillars are normally not considered and defined in food production system. Nevertheless, in the introduction we are describing the relation of the sustainability and food production and giving an explanation of the relation between the food production systems and the sustainability pillars which are considered for this review article. Like we mentioned before, we know that institutional sustainability is important to measure part of sustainability, but the focus was in the traditional pillars and the direct related new pillars to food production systems, culture and technology, therefore, we like to keep our title as we had in the original version.

Reviewer 3

* The manuscript “Review of sustainable pillars and the fulfilment in agriculture, aquaculture and aquaponic production” discusses on the present sustainable pillars and the present agricultural, e.g., agriculture, aquaculture and aquaponic production systems. The subject area of the manuscript is important in fulfilling the criteria in modern agricultural production technology. The manuscript is nicely narrated, however, there are many grammatical errors and mistakes. The manuscript is recommended to check thoroughly by native speaker. There are also some major issues that are required to solve before the manuscript accepted in Sustainability.

Thank you very much for your comments.

* I suggest to add discussion with the main body (observation) rather placing in separate

paragraph.

We think the separation between discussion and the main body is appropriate, not only because it is adopted to the editors instructions of Sustainability, but also we are discussing to core topics of the main body, sustainable pillars and food production systems and by adding the discussion to the main body it could indicate we are only discussing food production systems.

Reviewer 4 Report

After reading carefully the manuscript, my main concern is that the authors do not explain how they have performed their review and it is important to describe this methodology. There is a lack of a methodological framework of how they have performed the particular review.

 

The research questions could have been more specific and refer to:

1. To identify the key elements of their research

2. Why we need to perform this study

3. Which are the benefits

4. Which are the problems or difficulties of performing this review

 

What type of sources/digital library: Scopus, Science direct, Springer, Taylor and Francis, IEEE digital library, etc, the authors have consulted?

 

Which were the inclusion Criteria during their review. Please see below some examples

• Research field

* After reading carefully the manuscript, my main concern is that the authors do not explain how they have performed their review and it is important to describe this methodology. There is a lack of a methodological framework of how they have performed the particular review.

Thank you very much for your comments.

After your recommendation we added a methodological framework to our article.

Original: “none”

Modified version: “The initial literature research in June 2022 was performed to provide basic information about the sustainability concept in relation to food production, which provided the keywords for the review. The research was performed by searching the MDPI, Elsevier, IEEE, Wiley, Taylor & Francis, and Google Scholar databases, concentrating the research on the sustainability dimensions and food production systems. This differentiation helped to define a methodology with two main sections: analyzing the need to complement the traditional sustainability pillars in food production and the aspects of cultural heritage and technological production impacts, and reflecting these predefined sustainable pillars in different food production systems.

 

Therefore, we performed a systematic review of the three traditional pillars of sustainability—economic, social, and environmental—to analyze the different concepts and implement the following sub-questions:

  1. What are the details of the traditional sustainable dimensions?
  2. Is there a need to amplify this definition based on food production systems?
  3. How sustainable are the traditional food production systems (agriculture and aquaculture) are?
  4. How sustainable is an aquaponic production system in comparation to the traditional production systems?

 

We attempt to answer these sub-questions by: 1. describing the traditional sus-tainability dimensions; 2. based on the traditional production systems, we highlighted that culture and technology must be more specifically defined to better understand sustainable food production; 3. we analyzed two traditional food production systems, agriculture and aquaculture, and their sustainable impact in food production and compared these systems; and 4. then compared them to sustainable aquaponic food production. 

 

Although aquaponics is categorized as a sustainable production method, we want to compare aquaponic food production’s sustainability with the traditional production system, because aquaponics combines agriculture and aquaculture and both systems have some difficulties to overcome in accomplishing full sustainability.”

* The research questions could have been more specific and refer to: 1. To identify the key elements of their research; 2. Why we need to perform this study; 3. Which are the benefits; 4. Which are the problems or difficulties of performing this review.

Our main research field was sustainable food production, but divided into to three main areas; agriculture, aquaculture and aquaponics. Therefore, our main focus was on these production systems, but in addition we made an open investigation about different sustainable which are not considered in food production and are suitable to define better sustainability of food production. Since there is very view information about cultural and technological sustainability in direct food production, we opened our research to related areas and reviewed al types of scientific studies. Therefore, we used mainly open access texts from the last five years, but we also included standard authors related to our type and considered older scientific investigations.

* Which were the Exclusion criteria during the review. Please see below some examples: Not belong to the field of research, Non English, Publication date before….., Non scientific studies, Not related to the subject of interest.

We excluded articles that included external influences over food production systems, because we concentrated on the food production systems on themselves. Moreover, we investigated in different languages so we could have a more amplified few on the topic and evolution about the last years. 

* The authors need to perform also a detailed language editing, since sometimes Spanish words and phrases appear in the text.

We have evaluated the situation of the English quality of our article and we have decided to send the article for further editing to native English speakers so that we can have a better English quality of our manuscript. Furthermore, we changed all words and phrases that appeared in Spanish to English.

Round 2

Reviewer 1 Report

Comments to the authors:

The present study describes the sustainability pillars for food production in order to improve the sustainable food production and food security. The authors have proposed five sustainability pillars, which are not well connected to sustainable food production and food security. I suggest, it needs a connection to the present study rather generalizing each pillar. Otherwise, the papers are divided into two parts, firstly sustainability pillars and secondly food production system, which does not form a precise connection.

The quality of the paper and language have improved now. Though, the Ms still lack a precise connectivity.

Specific comments:

Method section- The parameters of systematic review are not followed, it needs to follow the clear cut method of systematic review.

Thank you for your comments.

We think that we have well connected the traditional pillars of sustainability with the proposed separation of culture from the social pillar and the separation of technology from the economic pillar to explain in a better way how economics, social aspects, environmental behavior, cultural heritage and technology impact food production in different systems. Therefore, we made this division in our article to explain why it is important to define culture and technology as separated sustainable pillars, which helps us to explain how this pillars impact food production and what practices or characteristics of a food production systems are sustainable and which ones are not.

 

* The quality of the paper and language have improved now. Though, the Ms still lack a precise connectivity.

We checked the document you attached to your comment, reviewed our article, and adopted a lot of your recommendations to improve the connectivity of our article. We marked the parts we adopted from your recommendations yellow and the parts we think from our version is more accurate in green. We hope that our article is more readable after these changes and that the understanding of our topic was improved. 

 

Specific comments:

* Method section- The parameters of systematic review are not followed, it needs to follow the clear cut method of systematic review.

Original: “The initial literature research in June 2022 was established to provide basic information about the concept of sustainability in relation with food production, which provided the keywords for the review. The research was performed by searching the MDPI, El Servier, IEEE, Wiley, Taylor & Francis, and Google Scholar databases, concentrating the research on the sustainability dimensions and food production systems. This differentiation helped to define a methodology with two main sections: analyzing the need to complement the traditional pillars of sustainability in food production and the aspects of cultural heritage and technological production impacts, as well as the re-flection of these predefined sustainable pillars in different food production systems.

Therefore, we performed a systematic review of the three traditional pillars of sustainability; economic, social and environmental to analysis the different concepts and implement the following sub-questions:

  1. What are the details of the traditional sustainable dimensions?
  2. Is there a need to amplify this definition based on food production systems?
  3. How sustainable are traditional food production systems (agriculture, aquaculture) are?
  4. How sustainable is an aquaponic production system in comparation to the traditional production systems?

We attempt to answer these sub-questions by; 1. describing the traditional dimensions of sustainability; 2. based on the traditional production systems, we ubicated culture and technology need to be more specific defined to implement a better under-standing of sustainable food production; 3. we analyzed two traditional food production systems, agriculture and aquaculture and their sustainable impact in food production and compered these systems 4. to sustainable aquaponic food production. 

Although aquaponics is categorized as a sustainable production method, we want to compare the sustainability of aquaponic food production with the traditional pro-duction system, because aquaponics is the combination of agriculture and aquaculture and both systems have some difficulties to accomplish full sustainability.”

The analysis of the traditional sustainable dimensions was performed reviewing the initial concept of sustainability and the adoption by international institutions during the last decades. Moreover, the analysis of the two traditional production systems (agriculture and aquaculture) showed that there are cultural and technological differences globally that need to be considered to define sustainable food production. Furthermore, food production was analyzed on the base of external influences which substituted the traditional production methods, like the case of aquaponic food production.

Although aquaponics is categorized as a sustainable production method, we want to compare the sustainability of aquaponic food production with the traditional pro-duction systems, because aquaponics is the combination of agriculture and aquaculture, and both systems have some difficulties to accomplish full sustainability.

This research was performed in three different languages; English, German and Spanish to gain different information and studies about the sustainable pillars. Moreover, the research in different languages helped to review articles from different countries and to understand the cultural heritage of food production and applied technology in different parts of the world.

For this research we utilized different types of articles (review and scientific studies) and book chapters from different areas where sustainable pillars are applied and defined, and about sustainability in food production systems. In general, the information is dated from 2018 to 2023, only established concepts and basic information about the topic is dated from before 2018.”

Modified: “Therefore, the following part concentrates on the three principal sustainability pillars, their classification, and the importance of the definition of the cultural and technological pillars of sustainability (Figure 1.).” 

 

* Add the heading ‘Results’ in the text after method section.

We decided to structure our article in this format because it was not designed for results form an experiment rather than for a review of sustainability and the application in the article mentioned food production systems. So, we decided to keep the current version “The concept of sustainability and the sustainable pillars” because we think it is more accurate for this review article due to the number of subtitles we implemented in this section. Furthermore, a format change would require major corrections in the article, because the discussion is also adopted to the current format. Also, we checked other review articles in MDPI´s Sustainability Journal and there are published articles that have the format you propose, but on the same time there are also a lot of articles published in the format we chose.
