[学术文献 ] 多国粮食限制出口背景下中国食物安全潜在风险与策略——基于大食物观视角 进入全文
中国知网
近年来,全球公共卫生事件和地缘冲突事件频发。面对重大突发事件的冲击,许多国家为保障本国粮食安全限制对外出口,这将对中国食物进口造成不利影响。文章对多国粮食限制出口前后中国食物进口变动进行分析,并用时间序列ARIMAX模型分析中国食物大类、谷物类、畜肉类和水产品类安全水平的主要影响因素,设定的主要因素有国际各类食物贸易动荡程度和中国食物受害风险,分析出当前中国食物安全水平主要受蛋白质类食物供给的影响,多国粮食限制出口对中国谷物类食物和水产品类食物供给影响不大,对畜肉类食物长期供给的影响需警惕。最后,本文基于多国粮食限制出口前后中国食物进口变动分析和实证结果提出未来在大食物观视角下保障中国食物安全的政策建议。
[学术文献 ] 大农业观的内涵与发展路径研究 进入全文

2024年政府工作报告首次将大农业观写入其中,强调“必须践行好大农业观、大食物观,始终把饭碗牢牢端在自己手上”。大农业观是党在农业领域的一次理论创新。深刻理解大农业观的内涵,并在大农业观的指导下探索农业发展具有重要的理论意义和实践意义。本文通过梳理大农业观提出的背景和概念的发展演变,提出从四个观念转变,四个产业结构变化来认识大农业观的内涵,并在此基础上探讨了大农业观下的农业发展路径,提出五条建议。
[学术文献 ] 大农业观与大食物观助力农产品供给保障策略探究 进入全文
中国知网
针对我国农产品供给所面临的新形势与新挑战,习近平总书记指出,我们需要秉持“大农业观”与“大食物观”,全面利用“两个市场两种资源”,采取多种途径和方式深入发掘食物资源潜力,以满足我国居民日益增长且日益多元化的营养健康需求。构建一个系统性的、整体性的农产品供给保障战略,不仅符合居民食物消费结构由“生存型”“温饱型”向“发展型”“享受型”转变的客观要求,也是为了消除不同农产品保障任务之间存在的潜在矛盾,保证政策协调连贯地实施。

研究目的:阐述多元化食物供给和耕地保护协同推进的逻辑、机制及路径,为新时代粮食安全问题提供新思路。研究方法:理论分析法、归纳演绎法。研究结果:(1)协同推进多元化食物供给和耕地保护是新时代粮食安全战略转型的本质要求、国家生态文明建设的核心需求、中国式农业现代化建设的必由之路及应对全球复杂格局的必然选择。(2)多元化食物供给和耕地保护协同推进具有理论同源性、根本目标一致性、核心价值同一性和实践过程联动性。(3)新时代耕地保护必须注重与山水林湖草沙全域全要素空间配置,要素重组、空间重构、产业重塑是大食物观下多元化食物供给和耕地保护协同推进的激活机制。(4)未来应从双轮驱动政策体系、耕地利用转型、食物消费结构多元化和创新全产业链利用模式等方面促进多元化食物供给和耕地保护协同推进。研究结论:大食物观下多元化食物供给和耕地保护协同推进有助于保障新时代国家粮食安全,对耕地保护转型和制度创新具有重要指导意义。
[学术文献 ] Applications of artificial intelligence (AI) in managing food quality and ensuring global food security 进入全文
科睿唯安WOS数据库
The food industry uses artificial intelligence (AI) to enhance food quality and security while proposing significant capital savings and resource optimization. Additionally, understanding machine learning (ML) techniques is essential for their effectiveness. Therefore, the gap lies in examining how industrial automation plays a crucial role in successfully implementing this new technology. To address this gap, this review explores AI’s potential to significantly enhance food safety by creating a more transparent supply chain management system. Therefore, the primary focus is exploring potential AI applications, such as artificial neural networks (ANN) and convolutional neural networks (CNN), for detecting food and agricultural product quality. The primary goal of utilizing these AI applications is to reduce human intervention and effort. These methodologies have advantages and disadvantages regarding theoretical knowledge and model interpretation.
[学术文献 ] The contribution of urban farming to urban food security: the case of "Buruan SAE" 进入全文
科睿唯安WOS数据库
This study focuses on urban farming practices in Bandung, West Java, known as Buruan SAE, a programme initiated by the Department of Food Security and Agriculture, Bandung. The objectives of this study are to analyse the effects of urbanisation on urban farming and to explore the potential of urban farming in supporting food security. This study uses a qualitative approach. The results of the study show 3 important issues: the diverse production of urban farming is able to meet the food needs of community members and some have already become independent farmers; there has been a change in the attitude of the people of Bandung city, through urban farming they have become 'farmers' a completely new activity for them; urban farming provides a source of income for the urban community. These findings suggest that urban farming can enhance the sustainability of the Buruan SAE community.
