Identifying and Prioritizing Factors Affecting the Sustainability of the Agricultural Supply Chain with the Fuzzy DEMATEL and Fuzzy SWARA Approach in the Era of Covid-19: A Case Study
Abstract
IntroductionThere is no doubt that the Covid-19 pandemic has had numerous adverse impacts on every aspect of human existence. In times of crises like epidemics throughout history, ensuring a sufficient food supply has always been a crucial concern. Given that the agricultural sector plays a vital role in the food supply chain and maintaining sustainability in this sector is essential for food security, this study aims to identify and prioritize the factors that influence the sustainability of the agricultural supply chain, specifically focusing on the wheat crop, during and after the Corona era. Materials and MethodsBased on the research background, the factors that impact the sustainability of the agricultural supply chain were determined. In the agricultural sector, like previous studies on supply chain sustainability, the study focused on the three dimensions of sustainability: economic, social, and environmental. However, experts suggest that the study is more centered on these three dimensions, which are particularly significant in the agricultural industry. By utilizing the Fuzzy Delphi method, 28 sub-criteria related to these hidden sustainability variables were identified. The Fuzzy DEMATEL method was then employed to examine cause-and-effect relationships and the interaction between criteria. Finally, the Fuzzy method was used to determine the degree of importance and weight of these criteria. Results and DiscussionTo achieve sustainable agriculture, research centers should prioritize the necessary research in this field, as highlighted by Sharghi et al. (2010). Farmers who possess more information about sustainability have been found to have more sustainable farms, confirming a direct correlation between these two factors (Afrous & Abdollahzadeh, 2011). The outcomes of the present study align with previous research, demonstrating that the level of attention given by research organizations to required research on sustainability is the most influential criterion within the causal group of sustainable procurement with a weight of 3.34, it holds the highest importance in the ranking according to the SWARA method. Updating and sharing information in DEMATEL's method has the fourth highest impact on other factors in the cause-and-effect group. However, in the SWARA's method was found to be the second most important factor, with a weight of 0.2403. Another study confirmed that the three main limitations of sustainable wheat production are the farmers' limited knowledge, lack of approved and resistant seeds, and inadequate management systems, especially for weeds. The use of local suppliers, specifically utilizing stored seeds from farmers, can lead to the spread of diseases and an increase in weed populations (Husenov et al., 2017). The proliferation of weeds leads to the squandering of production resources and a decrease in production levels. The most impactful factor for the sustainability of the wheat supply chain, as determined by the causal group, is the requirement of collaborating with an ISO-certified supplier. This criterion holds a significant weight of 0.4915 and is essential for achieving sustainable supply and design. Recognizing the significance of this criterion is crucial to enhance production and mitigate the risk of potential diseases. However, farmers, due to the expensive cost of modified seeds, resort to utilizing seeds from their previous crop. Based on the Fuzzy DEMATEL method, water consumption management ranked fifth among the criteria that influence other criteria. However, according to the Fuzzy SWARA method, it ranked second with a weight of 0.251. With water resources being scarce in the region, it is crucial to use water efficiently and prevent wastage, as this will positively impact productdid not support the significance of stopping gray marketing of products. According to experts, this study determined that the most effective criteria for the causal group in stabilizing the agricultural supply chain of wheat products during the Covid-19 era is to stop gray marketing. This criterion received the highest degree of importance, with a weight of 0.4469, in the dimension of sustainable distribution.Imports decreased because of the restrictions and quarantine measures, which led to a shortage of seeds for crops like wheat that relied on imports. Social distancing measures also caused a shortage of labor in agriculture, leading to a significant reduction in farming activities. By focusing on supply and sustainable design during epidemics and crises, there is an ability increased to manage the supply chain and positively impact other aspects of production sustainability. ConclusionBased on the results obtained, increasing farmers' awareness, and utilizing approved seeds can prevent resource wastage and enhance the stability of the supply chain. Additionally, reducing gray market activities can contribute to the supply chain's stability and ultimately enhance food security. Effective management of water consumption is also crucial for ensuring the sustainability of the supply chain, particularly due to the water scarcity crisis in the region. Enhancing the stability of the supply chain not only facilitates resilience during crises like Covid-19 but also promotes self-sufficiency in producing agricultural products essential for Iranian households, including wheat, which is a fundamental necessity.
