1. Introduction
Agriculture is a fundamental component of the global economic system as it sustains the livelihoods of approximately 86% of the rural population. It stands as one of the most significant economic sectors, with a notable contribution to national income. For instance, in 2018, the agricultural sector represented around 4% of the worldwide Gross Domestic Product (GDP), and in several developing nations, this figure exceeded 25% [
1]. As research on the adoption of novel practices and strategies in agriculture continues to expand, the connection between these developments and agricultural policy becomes increasingly significant. Among the emerging policy opportunities are initiatives aimed at empowering women farmers in developing countries to adopt beneficial innovative techniques, as well as the integration of marketing tools and strategies into public agricultural extension programs [
2]. Although many countries that once had agriculture-based economies have gradually shifted toward industrial and, subsequently, service-oriented structures, the agricultural sector continues to play a vital role in national development. It does so by supplying raw materials to other industries, generating employment opportunities, and maintaining its central function in food production, which remains a critical activity in numerous economies [
3].
Agricultural commodities have consistently held a significant place in global trade, reinforcing the importance of agricultural markets. One of the most notable features of economic transformation is the relative decline of agriculture in developing economies. Moreover, growth in exports from other sectors can sometimes undermine a nation’s agricultural base; nevertheless, due to rising global population and income levels, the demand for agricultural products is projected to increase. As such, the efficiency of a country’s agricultural trade practices will be a key indicator of its capacity to respond to growing demand [
4]. Understanding the environmental impacts of agriculture is an essential requirement for all nations in order to ensure sustainable agricultural production. It is crucial to develop agriculture–environment indicators at the national level and to establish monitoring systems capable of tracking changes in these indicators over time. Agricultural performance indicators support evidence-based decision-making by facilitating the monitoring of environmental outcomes in agricultural activities and identifying critical trends in resource use and production practices [
5].
Achieving sustainability in agriculture requires the fulfillment of specific economic, environmental, and social criteria. In addition, the adoption of a robust and well-structured decision-making framework is essential for guiding complex strategic choices in the agricultural sector. Such a framework plays a crucial role in identifying the most appropriate and effective partnership models that can facilitate a successful transition toward sustainable agricultural practices, particularly in the face of evolving environmental and socio-economic challenges [
6]. The overall goal of this study is to develop a comprehensive and integrated framework to evaluate the agricultural performance of 38 Organization for Economic Co-Operation and Development (OECD) countries through Multi-Criteria Decision-Making (MCDM) approaches in the context of sustainability and policy relevance.
There are many studies in the literature on agricultural performance evaluation using MCDM approaches; for example, Alphonce (1997) [
7] demonstrated the applicability of the Analytical Hierarchy Process (AHP) in agricultural decision-making within developing countries, particularly for subsistence farming contexts. Through a case study, AHP was employed to support decisions on field allocation, crop production methods, and the choice between subsistence and cash crops, incorporating resource-based criteria and sub-criteria into the analysis. Rezaei-Moghaddam and Karami (2008) [
8] assessed suitable models for sustainable agricultural development in Iran, comparing ecological modernization and de-modernization; using AHP with input from multiple stakeholder groups, they identified nine evaluation criteria. Their results suggested ecological considerations as the most critical factor, leading to the conclusion that the ecological model holds the highest priority for Iran’s sustainable agriculture.
Aktan and Samut (2013) [
9] analyzed the agricultural performance of Turkish provinces from the year 2009 using a two-stage Multi-Criteria Decision-Making approach, with Fuzzy AHP being employed to determine the weights of agricultural performance criteria, followed by the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method for provincial ranking. The integration of linguistic variables enhanced the model’s realism and reliability. Additionally, a sensitivity analysis was conducted to evaluate the robustness of the results against changes in weight parameters. Talukder et al. (2017) [
10] explored the use of the Elimination method, a type of MCDM, for assessing agricultural sustainability. Their study applied the method to a case study in coastal Bangladesh, highlighting its simplicity, speed, and applicability for ranking agricultural systems. While the approach demonstrated practical benefits, the authors also noted the importance of addressing certain limitations to ensure its effective implementation.
Cicciù et al. (2022) [
11] reviewed studies employing MCDM methods to assess agricultural sustainability, and based on 41 articles from the Web of Science, they found a rise in related publications after 2016, with France and China as leading contributors. AHP was the most commonly used method, while the Triple Bottom Line framework and farming systems were frequently considered. Their study highlighted that MCDM applications in this field remain limited and predominantly compensatory. Kumar and Path (2023) [
12] emphasized the relevance of United Nations Sustainable Development Goal 2, which targets ending hunger and ensuring global food security by 2030. They argued that achieving this goal requires integrating scientific disciplines, including mathematics and statistics, into agricultural practices. Highlighting agriculture’s central role in both developing and developed economies, they noted the complexity of decision-making due to conflicting factors. The authors reviewed the application of AHP in addressing agricultural decision-making problems, discussing models, data sources, and the effectiveness of AHP in improving decision precision.
Atlı (2024) [
13] examined the importance of implementing agricultural policies within a sustainability-oriented framework in competitive economies, noting that climate change, evolving market dynamics, and shifts in national and international agricultural policies had increasingly influenced the sector. They aimed to identify and rank the criteria affecting agricultural policy for sustainable marketing using the Best Worst Method, the results of which indicated that project cost was the most influential criterion, followed by social benefits and employment opportunities. The authors emphasized that economic, social, and environmental dimensions should be considered collectively in policy development to enhance sustainability in agricultural marketing. Headquartered in Paris, the OECD supports governments by offering policy recommendations aimed at reducing poverty and enhancing economic growth, stability, and cooperation in areas such as trade, agriculture, investment, entrepreneurship, technology, and development. Given its active role in promoting collaboration in the agricultural sector, the productivity of member countries remains a central concern for the organization [
14].
The specific objectives of this study are to (1) apply two MCDM methods—Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR)—under both Analytical Hierarchy Process (AHP)-based and equal-weighting strategies; (2) generate four separate country rankings based on these combinations; (3) integrate the rankings using the Borda count technique to produce a unified and robust performance order; (4) evaluate the consistency and sensitivity of the individual methods by employing Spearman’s rank correlation coefficients; (5) offer policy-relevant insights into agricultural sustainability and performance differences among OECD countries. The main contribution and motivation of the study lies in the integration of different MCDM techniques through the Borda count technique to generate a unified ranking, followed by an analysis of the effectiveness of these methods using Spearman’s rank correlation coefficients. To the best of the authors’ knowledge, this represents the first attempt in the literature to assess the agricultural performance of OECD countries using this approach.
2. Materials and Methods
This study aims to support the evaluation of the agricultural performance of OECD countries with Multi-Criteria Decision-Making (MCDM) methods. The general workflow plan is given in
Figure 1, with an explanation of the agricultural performance evaluation criteria determined for the OECD countries and the results of the Analytical Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR), Borda count technique, and Spearman’s rank correlation coefficient detailed in the following sections. This workflow provides a structured and transparent process, ensuring methodological clarity and replicability for future research in similar contexts.
The selection of evaluation criteria and Decision-Makers (DMs) represents a critical foundation for ensuring the reliability and relevance of the agricultural performance assessment framework. In this study, the criteria are identified through a comprehensive review of the literature on sustainable agriculture and performance measurement, with particular emphasis on economic, environmental, and structural dimensions relevant to OECD countries. The aim is to capture a holistic view of agricultural sustainability while reflecting indicators that are both measurable and policy-relevant. To ensure expert-driven weighting of the criteria, a group of knowledgeable DMs with academic and practical expertise in agricultural economics, rural development, and sustainability are consulted. Their inputs are used in the AHP to derive subjective weights based on informed judgments. This approach allows the integration of expert insight into the evaluation while the inclusion of an equal-weighting strategy ensures methodological balance and neutrality. The Borda count technique serves as the core integration mechanism for systematically comparing and reconciling the ranking outcomes of the applied MCDM methods. Together, these steps contribute to the transparency and robustness of the overall MCDM workflow illustrated in
Figure 1.
2.1. Data Set
The World Development Indicators (WDI) database, developed and maintained by the World Bank, is one of the most comprehensive sources of cross-country development data available for researchers and policymakers. It offers a wide array of statistical indicators covering economic, social, and environmental dimensions of development across more than 200 countries and regions [
15] and includes key metrics such as Gross Domestic Product (GDP), agricultural value added, land use, employment, poverty rates, and CO
2 emissions, enabling comparative and longitudinal analyses [
16,
17].
Due to its extensive coverage and standardized data collection methodology, WDI has been frequently utilized in empirical research addressing sustainability, agricultural productivity, and socio-economic performance [
18,
19]. The reliability and accessibility of WDI make it a fundamental resource for evaluating progress toward global goals, including the Sustainable Development Goals.
In this study, explanations regarding evaluation criteria obtained from WDI for the agricultural performance of OECD countries determined the following six criterion codes. The first criterion code (C1) pertains to grain yields (kg per hectare) of wheat, rice, maize, barley, oats, rye, millet, sorghum, buckwheat, and other mixed grains, which are reported as harvested and not adjusted for dry matter. While most grains are typically harvested within a relatively narrow moisture range, this may introduce minor variations in yield comparisons due to differences in the moisture content across grain types. The second criterion code (C2) is the application of mineral fertilizer (kg/ha of arable land) versus organic manures, which is reported by countries as either full-calendar-year or split-year applications. Here, arable land includes land used for temporary crops, meadows, market gardens, and fallow, but excludes shifting cultivation (i.e., swidden). The code C3 is the value added by agriculture, forestry, and fishing (% of Gross Domestic Product) which represents all sectors’ net outputs, which are calculated as the sum of outputs with intermediate inputs subtracted. Agricultural land (km2) (C4) is measured as the proportion of total land area composed of arable land as well as permanent crops and pastures. Permanent crops are not replanted after every harvest (e.g., coffee, cocoa, rubber, fruit trees, vines, and flowering shrubs) and do not include timber plantations; permanent pastures are used for five or more years and are either naturally occurring or cultivated. The fifth criterion code (C5) is employment in farming, hunting, forestry, and fishing (% of total national employment) involving working-age people producing goods and services for income/profit, including those temporarily absent from work. It refers to the percentage of the working-age population engaged specifically in agricultural activities such as crop cultivation, livestock production, and agricultural support services. According to the World Bank classification, this excludes sectors like forestry, fishing (unless related to aquaculture), and hunting, which are considered distinct from agriculture; therefore, this criterion reflects strictly farming-related employment. Finally, C6 is agricultural exports of raw materials (% of merchandise exports) that are unprocessed natural agricultural products used as inputs for manufacturing and industrial processes.
The decision matrix in
Table 1 for OECD countries is obtained from WDI, provided by the World Bank Group [
20]. The data in
Table 1 are cross-sectional; no outliers are excluded, and no correction is needed for the data. The MCDM techniques noted in the flowchart in
Figure 1 are detailed in the following sections.
2.2. Analytical Hierarchy Process
AHP is an MCDM technique developed by Thomas Saaty in the 1970s to produce solutions to complex problems [
21,
22], incorporating both quantitative and qualitative criteria. It enables the inclusion of individual or group preferences, expert opinions, experiences, judgments, and perspectives into the decision-making process, and addresses complex problems by structuring them within a hierarchical framework [
23,
24,
25]. The steps of the AHP method are given in
Appendix A.1.
2.3. Technique for Order Preference by Similarity to Ideal Solution
TOPSIS, an important MCDM method, was developed by Hwang and Yoon in 1981 [
26], based on the logic that the solution alternative is closest to the positive-ideal solution and farthest from the negative-ideal solution. In this method, the distances of all alternatives to the positive and negative ideal solutions are calculated, and the method has the feature of being directly applicable to the data. Alternatives can be ranked according to their distances to the ideal solution among the maximum and minimum values that the criteria can take; there must be more than one decision option for the method to be applicable. The TOPSIS method is based on the assumption that each criterion has a systematically increasing or decreasing benefit trend [
27]. The steps of the TOPSIS method are given in
Appendix A.2.
2.4. VlseKriterijumska Optimizacija I Kompromisno Resenje
The VIKOR method was developed by Opricovic in 1998 for the optimization of multi-criteria complex problems. This MCDM technique takes into account the special measure of ‘closeness’ to the ‘ideal’ solution, based on ranking and selection among alternatives under conflicting criteria [
28]. With its application, maximum group benefit and minimum regret are provided for a multi-criteria optimal compromise solution; it searches for the best alternative among the criteria and calculates the regret situation in case other alternatives are selected by considering the best alternative for the criteria. After calculating the regrets of the criteria, they are multiplied by the weight values of the criteria and, finally, a compromise solution is created between the maximum group benefit and minimum regret [
29,
30]. The steps of the VIKOR method are given in
Appendix A.3.
2.5. Borda Count Technique
The Borda count technique was originally introduced in 1784 by Jean-Charles de Borda as a voting technique [
31]. In the context of social choice problems, where deriving precise numerical evaluations from DMs can be challenging, the Borda count assigns scores to alternatives based on their relative rankings rather than absolute values [
32]. It assumes equal importance for each group in classification performance, and is also considered straightforward in terms of its implementation [
33].
In the Borda count scoring process, each of the alternatives within the evaluated group is assigned a rank-based score. The top-ranked alternative receives a score of
, the second-best receives
, and so on, with the lowest-ranked alternative receiving a score of
. The total Borda score for each alternative is calculated by summing these assigned values across all ranking classes. The final ranking of alternatives is then established based on their aggregated Borda scores. The mathematical representation of this procedure is provided in Equation (1) [
34,
35], where
is the ranking of alternative
with respect to criterion
and
is the total alternative number.
2.6. Spearman’s Rank Correlation Coefficient
Spearman’s rank correlation coefficient quantifies the degree of statistical association between two distinct stochastic sequences by evaluating the strength and direction of their monotonic relationship [
36,
37]. For example, assume two random variables,
and
, each consisting of
elements. Let
and
represent the
observation in
and
, respectively, where
. The values in both variables are ordered (either in ascending or descending order), resulting in two ranked sets denoted by
and
. Here,
corresponds to the rank of
and
corresponds to the rank of
.
Spearman’s rank correlation coefficient, which measures the strength and direction of the monotonic relationship between the two variables, can be computed using Equation (2) [
38]. However, in many practical applications, the precise values of the variables are less critical than their ranks; therefore, a simplified form of Spearman’s rank coefficient can be applied by calculating the rank differences
. The coefficient is then given by Equation (3):
4. Discussion
4.1. Comparison to Prior Research
Previous studies on agricultural performance evaluation have largely focused on either individual Multi-Criteria Decision-Making (MCDM) methods or limited geographic scopes. For example, Alphonce [
7] and Rezaei-Moghaddam & Karami [
8] utilized the Analytical Hierarchy Process (AHP) approach to evaluate local or national agricultural priorities, while Aktan and Samut [
9] applied Fuzzy AHP and VIKOR in a provincial context. However, these studies typically relied on a single weighting strategy and did not examine the comparative behavior of multiple MCDM models under different weighting schemes.
In contrast, the present study provides a broader and more systematic analysis by simultaneously applying both Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods to a comprehensive set of Organization for Economic Co-Operation and Development (OECD) countries. Furthermore, by incorporating two distinct weighting strategies—subjective (AHP-based) and neutral (equal weighting)—this research offers a multidimensional view of agricultural performance assessment. Most notably, while the earlier literature seldom reconciled differences between methods, our study employs Borda count aggregation to integrate rankings and mitigate methodological inconsistencies. This layered approach to performance evaluation, including sensitivity analysis via Spearman’s correlation, has not been widely explored in previous studies and thus represents a methodological advancement. Additionally, while Cicciù et al. [
11] noted that the literature on MCDM in agricultural sustainability remains fragmented and often compensatory in nature, our study presents a holistic hybrid framework that integrates multiple tools and decision perspectives. By doing so, it aligns more closely with the real-world complexity of agricultural systems and the multidimensional trade-offs faced by policymakers.
4.2. Research Implications
In this study, the agricultural performance of OECD countries was assessed using TOPSIS and VIKOR methods under two different weighting strategies: the AHP and equal weighting. The findings revealed that the VIKOR method produced more sensitive ranking outcomes compared to those obtained using TOPSIS, particularly when the weighting scheme changed. This observation was empirically supported by the Spearman rank correlation coefficients (
= 0.507 <
= 0.938), indicating greater variability in the VIKOR rankings due to changes in the weight structure. These results show that VIKOR methods are more sensitive under changing criteria for weighting conditions and have the potential to obtain different results. Furthermore, the individual rankings derived from the TOPSIS and VIKOR algorithms were aggregated using the Borda count technique under both weighting strategies. As presented in
Table 5, the final combined ranking achieved a high consistency score (
= 0.819), reinforcing the reliability of the integrated approach. This hybrid methodology, which combines Decision-Maker (DM)-based and neutral weighting schemes, offers a balanced and robust decision-support tool for evaluating agricultural performance across countries.
This study differs from the existing literature in terms of its contributions and general gains, as follows: (i) This study simultaneously employed both the TOPSIS and VIKOR methods, enabling a comparative analysis of the ranking results generated by each technique. A sensitivity analysis was conducted by applying two distinct weighting strategies—AHP and equal weighting—to observe the influence of weighting schemes on the final rankings. (ii) The empirical findings demonstrated that the VIKOR method is more responsive to changes in weight allocation, as evidenced by the Spearman rank correlation coefficients. (iii) To mitigate inconsistencies between methods, the ranking results obtained using TOPSIS and VIKOR were consolidated using the Borda count technique, yielding an integrated and more balanced final ranking. (iv) The aggregated ranking achieved a high degree of consistency, as reflected by the , underscoring the reliability of the combined decision-making framework. (v) This study presents a comprehensive and integrated decision-support approach—incorporating AHP, equal weighting, TOPSIS, VIKOR, and Borda count technique aggregation—which is relatively underexplored in the existing literature. (vi) The proposed model offers a comparative, methodologically robust, and policy-relevant ranking structure that can guide DMs and stakeholders involved in agricultural strategy development.
The findings of this study have several implications for research and practice. First, the demonstrated sensitivity of the VIKOR method to changes in weighting schemes highlights the importance of method selection and robustness testing in MCDM applications. Researchers should not assume stability in rankings without conducting sensitivity analyses, particularly when different weighting strategies are considered. Second, the integration of results through the Borda count offers a promising approach to synthesizing divergent rankings from multiple methods. This suggests that future studies should adopt aggregation techniques to enhance consistency and reduce uncertainty in multi-model evaluations. Third, the hybrid framework used in this study, which combines AHP, equal weighting, TOPSIS, VIKOR, and Borda count, serves as a scalable model for cross-national or regional performance assessments in agriculture and beyond. Researchers may extend this approach to evaluate sustainability in areas such as water resource management, energy efficiency, or rural development planning. Finally, the study underlines the value of comparative international assessments in guiding evidence-based agricultural policy. The ranking outcomes can help DMs identify performance gaps and design targeted interventions. Future research should build on this foundation by exploring additional MCDM techniques and incorporating fuzzy logic or gray theory-based weighting models to capture uncertainty and vagueness in expert judgments more effectively.
4.3. Policy Recommendations
The results of this study provide actionable insights for national policymakers, offering a clear basis for developing targeted strategies to improve agricultural performance. From a national policy perspective, countries that rank lower in the integrated performance index—such as Ireland in this study—are advised to undertake comprehensive evaluations of their agricultural systems, with particular attention to the criteria that have been identified as most influential in this analysis. The applied weighting schemes revealed that economic indicators (e.g., agricultural value added and export capacity), environmental sustainability (e.g., pesticide use and greenhouse gas emissions), and structural factors (e.g., land use efficiency and employment in agriculture) play critical roles in shaping the overall performance rankings. Accordingly, national policymakers should focus on refining sustainability strategies that directly target these high-weighted criteria. For instance, improvements in resource use efficiency, reduction in input intensity, and enhancement of agri-environmental programs could significantly contribute to better performance. Moreover, revisiting investment priorities to support technological modernization, sustainable production techniques, and farmer education—particularly in regions lagging behind—may offer tangible gains. The decision-support framework proposed in this study enables countries to benchmark their current standing against peers using a transparent, multidimensional structure. Moreover, the findings and suggested policy actions are broadly consistent with the strategic goals and thematic emphasis given by the World Bank and Organization for Economic Co-Operation and Development (OECD), particularly in terms of enhancing agricultural sustainability, improving resource efficiency, and fostering inclusive rural development [
56]. By interpreting their relative position through the lens of weighted criteria, policymakers can not only identify key weaknesses but also prioritize corrective actions in a more targeted and evidence-based manner.
5. Conclusions
Assessing agricultural performance necessitates a multidimensional perspective encompassing economic, environmental, and structural factors. In this study, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods were applied under both Analytical Hierarchy Process (AHP)-based and equal-weighting schemes to evaluate 38 Organization for Economic Co-Operation and Development (OECD) countries. Overall, the proposed hybrid framework offers a balanced and reliable decision-support tool by integrating both subjective and objective weighting strategies. The principal contribution and motivation of this study are rooted in the integration of multiple Multi-Criteria Decision-Making (MCDM) techniques through the Borda count method to establish a unified and comprehensive ranking framework. This was further complemented by a comparative effectiveness analysis using Spearman’s rank correlation coefficients to evaluate the consistency and sensitivity of the applied methods. This study assesses the agricultural performance of OECD countries using this hybrid decision-making approach, offering a novel perspective for policy development and methodological advancement. This study has several limitations that should be considered. The AHP-based weighting process involves expert judgments, which may introduce subjectivity despite the balancing effect of the equal-weighting scheme. The analysis is limited to OECD countries, restricting the generalizability of the findings to other regions with different agricultural contexts. Additionally, the study assumes uniform policy and environmental conditions across countries, potentially overlooking national differences. While the Borda count provides a practical aggregation method, it does not account for potential interdependencies among criteria or methods. Lastly, the framework does not explicitly address uncertainty, which could be improved in future studies through fuzzy or probabilistic approaches.
