Food banks play a significant role to ensure food security through surplus food recovery and redistribution to economically deprived and marginalized people. Food bank is a recent phenomenon in several countries including India. The purpose of this paper is to identify challenges and barriers that impede the growth and adoption of food banks in the Indian context and to evaluate critical barriers by prioritizing them. A total of 14 barriers have been identified through literature survey, qualitative interviews with different stakeholders of food banks in India and expert's inputs. These barriers have been clustered into 7 categories - Policy and regulation, financial resources, infrastructure and human resources, planning and coordination, knowledge, uncertainty, and characteristics of food, of main barriers. Then, DEMATEL is used to find the cause-effect relationship among the identified barriers. A network of inter-relationship among the identified barriers is devised using Analytic Network Process (ANP) using the output from DEMATEL. Results of DEMATEL indicates that lack of planning and coordination is the most significant barrier that hinders the growth and sustenance of food banks in India. Also, lack of infrastructure and human resources are the major effect of the other barriers. Further, the financial barrier attains maximum weight in the ANP process and came out to be the most critical barrier. This study can be help food banks and policy makers to devise the plans for sustenance of the food banks. To the best of our knowledge, this is the first attempt ever to identify and prioritize the barriers for the food banks.

粮食银行通过回收剩余粮食并将其重新分配给经济贫困和边缘化人群，在确保粮食安全方面发挥着重要作用。食物银行是包括印度在内的几个国家最近出现的现象。本文的目的是确定在印度背景下阻碍食品银行发展和采用的挑战和障碍，并通过对其进行优先排序来评估关键障碍。通过文献调查、对印度食品银行不同利益相关者的定性访谈以及专家的意见，共确定了 14 个障碍。这些障碍分为 7 类——主要障碍的政策和法规、财政资源、基础设施和人力资源、规划和协调、知识、不确定性和食品特性。然后，DEMATEL 用于查找已识别障碍之间的因果关系。使用 DEMATEL 输出的分析网络过程 (ANP) 设计了已识别障碍之间的相互关系网络。DEMATEL 的结果表明，缺乏规划和协调是阻碍印度食品银行发展和维持的最重要障碍。此外，缺乏基础设施和人力资源是其他障碍的主要影响。此外，财务障碍在 ANP 过程中达到最大权重，并成为最关键的障碍。这项研究可以帮助食品银行和政策制定者制定食品银行的维持计划。据我们所知，这是首次尝试确定食品银行的障碍并对其进行优先排序。
