Potassium (K) has received little attention as a potential yield-limiting factor in cropping systems. Here we investigated the K status in intensive cereal cropping systems in Indonesia, which are representative of many other Southeast Asian countries. Our analysis included nutrient input–output balance, leaf nutrient status, long- and short-term fertilizer trials, and farmer surveys. We revealed that soil K levels alone are insufficient to meet plant requirements, and current fertilizer applications are inadequate to prevent K deficiencies and large negative annual soil K balances in farmer fields (average −62 kgK ha−1). On-farm fertilizer trials indicated that nearly 80% of rice crops and 70% of maize crops achieved higher yields with the application of K fertilizer. Addressing K limitations will require an enhanced capacity to predict crop responses to K fertilizer, together with long-term, flexible fertilizer and crop residue management strategies. Furthermore, similar K limitations have probably emerged in other regions globally due to intensive cropping with insufficient K replenishment, which must be addressed to close yield gaps on existing farmland. Future yield improvements will require a closer examination of specific production factors and their interactions. This study quantifies potassium (K) limitations in Indonesia’s intensive cereal cropping systems and reveals that current soil K levels and fertilizer applications are inadequate to meet crop needs, exacerbating the existing yield gap in rice–maize systems in Indonesia and other countries in Southeast Asia.
钾(K)作为种植系统中一个潜在的产量限制因素,很少受到关注。在此,我们调查了印度尼西亚密集型谷物种植系统中的钾状况,该系统在许多其他东南亚国家具有代表性。我们的分析包括养分投入产出平衡、叶片养分状况、长期和短期肥料试验以及农民调查。我们发现,仅靠土壤中的钾含量不足以满足植物的需求,目前的施肥量也不足以防止钾缺乏症和农民田地中每年土壤钾的大量负平衡(平均-62 kgK ha-1)。农田施肥试验表明,近 80% 的水稻作物和 70% 的玉米作物在施用钾肥后获得了更高的产量。要解决钾肥不足的问题,就必须提高预测作物对钾肥反应的能力,同时制定长期、灵活的肥料和作物残留物管理战略。此外,全球其他地区可能也出现了类似的钾肥限制,原因是密集种植导致钾肥补充不足,必须解决这一问题,以缩小现有农田的产量差距。

A scoping review of cultivated meat techno-economic analyses to inform future research directions for scaled-up manufacturing 栽培肉技术经济分析范围审查,为扩大生产规模的未来研究方向提供信息

Techno-economic analyses offer insights into how industrial cultivated meat (CM) production could achieve price parity with conventional meat. These analyses use scaling practices, data and facility designs for related bioprocessing fields, including large (≥20,000 l) stirred tank bioreactors and suspension-tolerant, continuously available cell lines. This approach is inconsistent with most primary CM literature, which parallels bench-scale tissue engineering. TEAs published to date demonstrate that, under the current technological paradigm, CM is unlikely to be competitive with conventional meat. Scale-up feasibility may hinge on cost-saving areas such as use of plant-based media components, food-grade aseptic conditions and extensive scaling of related supply chains. Research must address knowledge gaps including serum-free differentiation, new bioreactor designs and facility design before CM can become a viable alternative to animal-based meat production. Technological advancements are needed before cultivated meat can supply dietary protein at a competitive cost and with lower environmental impacts than livestock production. This Review explores how techno-economic analyses can guide research towards providing sustainable scaled-up cultivated beef production.
技术经济分析为工业化培植肉(CM)生产如何实现与传统肉类价格持平提供了见解。这些分析使用了相关生物加工领域的扩展实践、数据和设施设计,包括大型(≥20,000 升)搅拌罐生物反应器和耐悬浮、连续可用的细胞系。这种方法与大多数初级中药文献不一致,后者与台架规模的组织工程相似。迄今为止发表的 TEA 表明,在当前的技术模式下,CM 不可能与传统肉类竞争。扩大规模的可行性可能取决于节约成本的领域,如使用植物培养基成分、食品级无菌条件和相关供应链的广泛扩展。研究必须填补知识空白,包括无血清分化、新型生物反应器设计和设施设计,才能使中药成为动物肉类生产的可行替代品。

The full picture of people’s realities must be considered to deliver better diets for all 必须全面考虑人们的实际情况,为所有人提供更好的饮食

Efforts to address poor-quality diets have stepped up considerably in recent years, but the problem of inadequate, unhealthy, unsustainable and unequal diets persists. Here we argue that to get policies and interventions working more effectively and equitably, a fresh approach is needed—one that considers the full picture of people’s realities. People’s realities interact to shape the way people respond to and engage with policies and interventions, thereby influencing their impact, particularly, albeit not only, on dietary inequalities. We propose a tool that brings together key realities that shape impact, including the material, economic and psychosocial realities that people face in their households, families, food environments, social interactions and cultures. The purpose of the tool is to help policymakers, intervention practitioners and researchers committed to improving diets achieve greater success by helping them think through the full picture of people’s realities when identifying, designing, implementing and evaluating policies and interventions. Engaging with people’s realities is key to the success of policies and interventions aimed at achieving better diets for all. Drawing on social practice theory, this Perspective proposes a tool—the full picture—to help researchers, practitioners and policymakers think through the full range of people’s interacting realities that shape the impact of policies and interventions designed to improve diets.
近年来,解决劣质饮食问题的努力已大大加强,但饮食不足、不健康、不可持续和不平等的问题依然存在。在此,我们认为,要使政策和干预措施更有效、更公平地发挥作用,就需要一种全新的方法--一种考虑到人们现实全貌的方法。人们的现实情况相互作用,形成了人们对政策和干预措施的反应和参与方式,从而影响了政策和干预措施的效果,特别是对饮食不平等的影响,尽管不仅仅是饮食不平等。我们提出了一种工具,它汇集了影响效果的关键现实,包括人们在家庭、家人、饮食环境、社会交往和文化中所面临的物质、经济和社会心理现实。该工具旨在帮助致力于改善膳食的政策制定者、干预措施实施者和研究人员在确定、设计、实施和评估政策和干预措施时全面考虑人们的实际情况,从而取得更大的成功。

Metal(loid) contaminants in food pose a global health concern. This study offers a global analysis of the impact of nanomaterials (NMs) on crop responses to metal(loid) stresses. Our findings reveal that NMs have a positive effect on the biomass production of staple crops (22.8%), while showing inhibitory effects on metal(loid) accumulation in plants (−38.3%) and oxidative damage (−21.6%) under metal(loid) stress conditions. These effects are influenced by various factors such as NM dose, exposure duration, size and composition. Here we introduce a method using interval-valued intuitionistic fuzzy values by integrating the technique for order preference by similarity to an ideal solution and entropy weights to compare the effectiveness of different NM application patterns. These results offer practical insights for the application of NMs in similar multi-criteria decision-making scenarios, contributing to sustainable agriculture and global food safety. Nanomaterials positively impact staple food biomass production, reducing metal(loid) accumulation and mitigating oxidative damage in plants under stress conditions. This study provides practical insights into evaluating various nanomaterial application approaches, highlighting their potential for promoting sustainable agriculture and improving food safety.
食品中的金属污染物是一个全球性的健康问题。本研究全面分析了纳米材料(NMs)对作物应对金属(loid)胁迫的影响。我们的研究结果表明,在金属(loid)胁迫条件下,纳米材料对主要作物的生物量生产(22.8%)有积极影响,同时对植物体内的金属(loid)积累(-38.3%)和氧化损伤(-21.6%)有抑制作用。这些效应受多种因素的影响,如非金属矿物剂量、暴露时间、大小和成分。在此,我们介绍了一种使用区间值直觉模糊值的方法,该方法综合了通过与理想解的相似性进行排序偏好的技术和熵权重来比较不同 NM 施用模式的有效性。这些结果为在类似的多标准决策情景中应用核磁提供了实用的见解,有助于实现可持续农业和全球食品安全。

The social dimension of sustainable diets, which addresses the impacts of food value chains on people, animals and communities, is under-represented in the food systems field. We present a definition of the social dimension of sustainable diets, clarify its boundaries and propose corresponding outcomes. Three case studies highlight the connectivity of social outcomes with the health, environment and economic dimensions of sustainable diets. The continued development of social metrics, data and methods and the implementation of integrated solutions co-developed with affected communities are needed to transform systems and structures that perpetuate unjust and inequitable food systems outcomes. The social impacts of food supply chains on people, animals and communities need to be integrated into sustainable dietary transformations. Here the social dimension of sustainable diets is defined and explored through case studies. Solutions are proposed to support just dietary transformations.
可持续膳食的社会维度涉及食品价值链对人类、动物和社区的影响,但在食品系统领域的代表性不足。我们对可持续膳食的社会维度进行了定义,明确了其边界,并提出了相应的成果。三项案例研究强调了社会成果与可持续膳食的健康、环境和经济层面之间的联系。我们需要继续开发社会衡量标准、数据和方法,并实施与受影响社区共同开发的综合解决方案,以改变使不公正和不公平的粮食系统结果长期存在的系统和结构。

This study presents a revised version of the Food Compass nutrient profiling system that incorporates the latest evidence linking diet and health—and which has been validated against health outcomes in a US population.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"5 11","pages":"911-915"},"PeriodicalIF":23.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43016-024-01053-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142384624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indigenous peoples are frequently denied the right to own, control and use their traditional lands and resources. Using the example of the Burdekin plum, we explore how this undermines resource access and benefit sharing with Indigenous peoples and hinders scientific research in food innovation.
土著人民经常被剥夺拥有、控制和使用其传统土地和资源的权利。我们以伯德金李子为例,探讨了这种情况如何破坏了土著居民的资源获取和利益分享,以及如何阻碍了食品创新方面的科学研究。
