This paper presents a general analysis of agricultural holdings in Romania. Thus, in this study, the economic size of the agricultural holding, the utilised agricultural area, the total crop production and the gross farm income were analysed, depending on the size of the agricultural holdings expressed in standard output. In addition, to clearly highlight the existing situation, statistical indicators such as standard deviation, coefficient of variation and growth rate were calculated. The current disparities are significant, and there is no clear evidence that they will be reduced or eliminated, because the structural problems facing Romanian agriculture can only be debated over a long period of time. The data used were extracted from the Farm Accountancy Data Network (FADN), for the period 2007-2021. The obtained results support the fact that the average economic size at the level of agricultural holdings in Romania is relatively stable, as far as this indicator is concerned. At the same time, the utilised agricultural areas have decreased and the total crop production has increased for all types of economic sizes, except for holdings with an economic size between 8,000 and 25,000 EUR.

Maintaining a rural-urban balance is absolutely necessary in the context of the challenges related to food security and environmental protection as well as the perspectives of urban agglomeration. This paper highlighted the impact of the main events from the last 30 years on the rural population. This study used the vector autoregressive model (VAR) to investigate the estimates and analyse the dynamic impact of innovations on the system of variables. Key issues that influenced certain periods in the analyzed interval were highlighted, which clearly show the impact on the analyzed variables using variance decomposition. The cost of living in rural areas is increasing, so more and more inhabitants give up growing certain crops or raising certain animals, thus having to search for food to survive, leading to additional wage income to cover these costs.

This article examines how circularity can be measured and evaluated in the agricultural sector. Circularity represents a key approach for promoting sustainability in agriculture and for the efficient management of resources. Through a comprehensive review of the scientific literature and employing rigorous selection methods, we identify the relevant indicators and tools for assessing circularity in the agri-food chain. The initial bibliometric analysis was performed by using a Biblioshiny instrument from R package tool Bibliometrics. Additionally, this article analyzes the methodologies based on the indicators and metrics that can be applied to measure the restorative capacity and effectiveness of the agricultural system. Most current research follows the 3R principles of the circular economy and establishes an evaluation index system based on the regional characteristics. Methods such as the multi-criteria decision analysis, data envelopment analysis, and life cycle assessment are the most used to date. For the micro-level analysis, system dynamics, material flow analysis, and emergy analysis were the most suitable. Our results provide a clear perspective on the current state of the research in the field of measuring circularity in agriculture and lay the groundwork for the future development of effective strategies for implementing the circular economy in this crucial sector.

Agriculture is a fundamental aspect of our society, providing food and resources for a growing population. However, climate change is putting this sector at risk through rising temperatures, changing rainfall patterns and an increase in the frequency and intensity of extreme weather events. Our study highlights the need to address climate change in a differentiated way, taking into account the specificities of each agricultural sector, and therefore aims not only to organise and summarise current research but also to fill an important gap in the existing literature by focusing on the impact of climate change on vegetable crops. The topic was researched using the Web of Science and Scopus databases, where 219 publications were thoroughly reviewed and only those that fully addressed the impact of climate change on vegetable crops were selected. Of the 219 publications reviewed, only 53 focused exclusively on the effects of climate change on vegetable crops, indicating the need for more specialised research in this area, especially given the complex challenges that climate change poses not only in terms of yield but also non-trivial quality and food safety, and can be considered a future research prospect.

The purpose of this study was to investigate the preferences of Romanian consumers when purchasing agri-food products, with a focus on products from family farms, and to identify pathways for promoting family farms’ outputs for enhancing the development of rural areas and the local economy. For this, a survey was carried out using a questionnaire as the main tool. Firstly, the data collected were analysed from a descriptive point of view. Then, multiple linear regression and the chi-square test were used to determine the relationships between variables, and ANOVA was used to identify significant differences between groups. The results revealed that consumers with a higher level of education are more confident in certified products and are better informed, with a greater ability to distinguish certified from non-certified products through logos. Finally, the results indicate an opportunity for family farms to sell their products for a higher price within a secure market, mainly in urban areas. However, for this to happen, it is necessary to implement a quality scheme, highlighting the origin and originality of the product (product obtained from a family farm, including logo) coupled with awareness campaigns on the advantages that this product has, both for the consumer and the farmer or the region it comes from. These aspects could improve the development of rural areas from all points of view.

The aspects highlighted in this paper refer to the application of fertilizers and plant protection products to the wheat crop, and their impact on total production, competitiveness in export markets, price optimization as a result of increased harvest quality, and not least row, ensuring farmers’ incomes. The present analysis concerned the areas cultivated with wheat, and the productions achieved in relation to the quantities of fertilizers and protection products used in wheat cultivation, in Romania, Germany, Spain, France, Italy, Hungary, Poland and the UK. The analysis highlighted that, the average productions are influenced both by the technology used, by the fertilization and treatments applied, as well as by other synergistic factors that intervene in wheat crops. In countries such as Spain and Italy, the correlation between the amounts of N (nitrogen), P₂O₅ (phosphorus), K₂O (potassium) and the average production of wheat is insignificant, but in Romania and Hungary, there is a strong, direct connection between the number of fertilizers used and the average wheat crop yield. In Romania and Hungary, there is a very significant connection, but the production link average with pesticides is negative, while in Germany, the correlation is direct and quite intense for all types of fertilizers used, while the use of pesticides has a lower influence on average wheat production. In this study, we also applied a multiple regression model; in which the dependent variable was the average yield of wheat per ha and the independent variables were the average quantity of pesticides and fertilizers used. We used the “t Stat” values for each coefficient to determine whether the coefficient is equal to zero; where a high value of “t Stat”, greater than 2; indicates the fact that the coefficient is significantly different from the value zero. The “p-value” for each coefficient indicates the probability that the coefficient has the value zero. A value below the significance level of 5% results in a coefficient significantly different from zero and with an impact on the dependent variable. The use of fertilizers on wheat crops has a synergistic effect as shown by the multiple linear regression analysis which demonstrated a strong direct relationship, particularly with the amount of N, K₂O and P₂O₅ applied.

Potatoes and tomatoes are the key vegetables of Romanian agriculture, due to their consumption and the large growing areas. The paper analyses import and export of potatoes and tomatoes, and import and export prices for these vegetables, while based on that the Gini coefficient was calculated. According to the value of the Gini coefficient, the concentration of potato import is relatively low, while the export concentration is considerably higher. A similar situation is with tomato, as the values of the Gini coefficient indicate low concentration related to import and relatively high concentration related to export. Association with foreign partners, farmer orientation to quality certifications, investment in infrastructure and efficient marketing are some solutions that can improve the Romanian vegetable market.

Cooperatives are known worldwide as important institutional commitments to overcome the constraints faced by small farmers in developing countries. We conducted an in-depth investigation in order to identify the reasons behind the underdevelopment of agricultural cooperatives in Romania, as well as the solutions that the representatives of cooperatives see, starting from the premise that they are the main connoisseurs of this activity, knowing the strengths, but especially the weaknesses of this activity, by administering a questionnaire-based survey as the main research tool. Clearly, cooperative representatives are aware of the socio-economic implications and role of cooperatives, with average values closer to “total agreement”, especially in terms of contribution to food security.

In recent years, climate change has begun to put pressure on humanity and affect natural and human systems. The aim of this paper is to provide an improved understanding of the state of the literature on the impacts of climate change that can be addressed through measures related to disaster risk reduction, sustainable agricultural practices, and the circular economy. This review also represents a valuable and fundamental reference for both researchers and practitioners in these fields. A total of 74,703 articles (climate change adaptation, 45,030; disaster risk reduction, 5920; sustainable agricultural practices, 7940; circular economy, 15,813) published between 1990 and 2022 were extracted from the Web of Science Core Collection, and the links between these areas were mapped using VOSviewer. There has been an increase in the amount of published research on these four topics since 2007, indicating the increasing involvement of researchers to address these topics, influenced by the concerns of national and international bodies to address these changes.

The study analyzes the awareness of the effects of climate change on agriculture and the measures that should be implemented in this regard from the farmer’s perspective, taking into account the financial and promotional measures supported by the European Union for farmers. Thus, the study tracks the level of openness of farmers to implementing the measures that European policy makers will take in the coming period. Taking into account the fact that agriculture plays a particularly important economic role, due to the share of agricultural products in Romania’s total exports, particularly in plant production, a quantitative survey was carried out among Romanian farmers, using a questionnaire as an instrument, with a total of 407 respondents. The farmers interviewed undoubtedly recognize that the problems they face are caused by the effects of climate change and are willing to adapt, seek and implement the necessary solutions. The most problematic climatic phenomenon identified by farmers (71.5%) is drought, with negative effects on their activity. At the same time, 54.15% of the respondents believe that the effects of climate change are affecting their business through lower yields. Although the farmers interviewed are willing to implement solutions to combat climate effects, 80.34% of them are not considering revising cropping patterns, giving more importance to market demand than to practices that protect the environment. In conclusion, as long as farmers feel and understand the effects of climate change, it cannot be a myth, especially if they are willing to adapt to these challenges.
