    在世界各国实现向可持续粮食系统过渡的努力中,粮食环境是一个重要因素。这项研究的目的是制定并优先考虑向布基纳法索政府提出的行动,以创造健康的食品环境,这将有助于减少各种形式的营养不良和非传染性疾病。
    国家专家聚集在一起,通过遵循健康食品和环境政策指数(Food-EPI)方法的多步骤评估过程,确定并优先考虑填补所发现空白的行动。
    向布基纳法索政府建议了多达20项优先政策行动。政策部分的行动主要侧重于食品促销和营销的监管,特别是对孩子们来说,基础设施支持部分的其他人主要侧重于政治领导,即,政府为改善食品环境提供了强有力的政治支持,人口营养,与饮食有关的非传染性疾病及其不平等。
    向政府建议的优先行动将加强对政府决策的宣传,以在该国创造更健康的食品环境。
    UNASSIGNED: The food environment is an important factor in the efforts of countries worldwide to achieve a transition to sustainable food systems. The objective of this study is to formulate and prioritize actions to be addressed to the government of Burkina Faso for the creation of a healthy food environment, which will contribute to reducing malnutrition in all its forms and non-communicable diseases.
    UNASSIGNED: National experts were brought together to identify and prioritize actions to fill the gaps identified through a multi-step assessment process following the methodology of the Healthy Food and Environment Policy Index (Food-EPI).
    UNASSIGNED: Up to 20 priority policy actions were recommended to the Burkina Faso government. Actions in the policy component focused mainly on regulation of food promotion and marketing, particularly to children, and others in the infrastructure support component focused largely on political leadership, i.e., strong and visible political support from the government to improve the food environment, population nutrition, diet-related non-communicable diseases and their inequalities.
    UNASSIGNED: The priority actions to be recommended to the government will strengthen advocacy for government decisions to create a healthier food environment in the country.

    食物系统和健康结果之间错综复杂的关系,被称为食物-营养-健康关系,与环境问题相交。然而,在使用复杂系统理论评估全球辛迪加的食物系统方面,仍然存在文献空白,特别是像儿童这样的弱势群体。这项研究旨在设计一个系统动力学模型,以促进对食物系统与全球辛迪加之间联系的理论理解。特别关注它们对五岁以下儿童的影响。该框架是通过文献综述和作者对食物之间关系的见解而开发的,健康,以及全球儿童联合犯罪的环境因素。概念模型提出了17个因素,有26个连接和6个反馈回路,分为以下5组:环境,经济,学校相关,家庭相关,和孩子有关。它描绘并阐明了包括超重在内的全球联合组织组成部分之间的机制,患有营养不良,和气候变化。这些发现揭示了食物系统和健康结果之间的潜在相互作用。此外,该模型通过纳入代表环境及其自然资源的外部层,整合了社会生态模型的要素。因此,公共政策和干预措施的制定应包括环境因素,以有效应对全球辛迪加带来的复杂挑战。
    The intricate relationship between food systems and health outcomes, known as the food-nutrition-health nexus, intersects with environmental concerns. However, there\'s still a literature gap in evaluating food systems alongside the global syndemic using the complex systems theory, especially concerning vulnerable populations like children. This research aimed to design a system dynamics model to advance a theoretical understanding of the connections between food systems and the global syndemic, particularly focusing on their impacts on children under five years of age. The framework was developed through a literature review and authors\' insights into the relationships between the food, health, and environmental components of the global syndemic among children. The conceptual model presented 17 factors, with 26 connections and 6 feedback loops, categorized into the following 5 groups: environmental, economic, school-related, family-related, and child-related. It delineated and elucidated mechanisms among the components of the global syndemic encompassing being overweight, suffering from undernutrition, and climate change. The findings unveiled potential interactions within food systems and health outcomes. Furthermore, the model integrated elements of the socio-ecological model by incorporating an external layer representing the environment and its natural resources. Consequently, the development of public policies and interventions should encompass environmental considerations to effectively tackle the complex challenges posed by the global syndemic.

    粮食生产和消费模式的增加导致城市粮食磷足迹增加,导致了全球范围内的一系列资源和环境问题。我们使用物质流分析量化了非洲城市基苏木的食物磷足迹。我们的目标是开发基苏木的可持续磷管理框架,以便该市减少粮食系统中的磷损失。我们的结果表明,在2023年,基苏木食品系统中食品磷的进出口分别为2730.26±2.7%tPyr-1和3297.05±2.4%tPyr-1。基苏木食物系统中存在-566.79±-18%tPyr-1食物磷赤字。作物种植子系统径流/淋溶/侵蚀损失,家庭消费子系统废物损失,和坑厕所子系统黑水流失是磷流失进入环境的主要途径,也是城市食物磷足迹的主要贡献者。2030年情景分析表明,在从磷投入到废物处置的整个生命周期过程中实施全面的情景方案是未来减少磷损失和抑制食品磷足迹增长的最佳选择。我们的研究表明,2023年基苏木粮食系统的食物磷足迹为0.67kgPcap-1yr-1,仍处于较低水平,但随着城市社会经济发展的改善,可能会进入持续上升趋势。在我们的框架中,我们提出了一些基本措施,包括尿液分离,安装化粪池,调整膳食结构,卫生处置设施的灵活布局,和有机废物流的分离,以减少基苏木的食物磷足迹。鉴于维多利亚湖沿岸城市的相似性,我们的计算方法和管理策略可以应用于该地区的其他城市。
    Increased food production and consumption patterns have resulted in higher urban food phosphorus footprints, leading to a series of resource and environmental problems worldwide. We quantified the food phosphorus footprint of the African city of Kisumu using substance flow analysis. Our aim was to develop Kisumu\'s sustainable phosphorus management framework so that the city would reduce phosphorus losses into the food system. Our results show that in the year 2023, the import and export of food phosphorus in the Kisumu food system was 2730.26 ± 2.7% t P yr-1 and 3297.05 ± 2.4% t P yr-1, respectively. There was -566.79 ± -18% t P yr-1 food phosphorus deficit in the Kisumu food system. Crop planting subsystem runoff/leaching/erosion loss, household consumption subsystem waste loss, and pit latrine subsystem blackwater loss are the major pathways of phosphorus losses into the environment and the main contributors to the food phosphorus footprint in the city. The 2030 scenario analysis shows that implementing a comprehensive scenario scheme throughout the entire lifecycle process from phosphorus input to waste disposal is the best choice for reducing phosphorus losses and suppressing the growth of food phosphorus footprint in the future. Our study shows that the food phosphorus footprint in the Kisumu food system was 0.67 kg P cap-1yr-1 in 2023, which is still at a low level but may enter a continuous upward trend with the improvement of socio-economic development of the city. In our framework, we have proposed a few essential measures that include urine separation, installation of septic tank, adjustment of dietary structure, flexible layout of sanitary disposal facilities, and separation of organic waste streams to reduce food phosphorus footprints in Kisumu. Given the similarity of cities along the shores of Lake Victoria, our calculation methods and management strategies can be applied to other cities in the region.

    本文遵循高粱,一个土著,但目前利用不足,南非的谷物,通过六次相遇,发现其改变国家粮食体系的潜力。通过从不同的角度听故事,这表明,高粱的重新纳入不仅可以使饮食多样化,但也可能走向打破殖民地对什么是理想食物的刻板印象。它采用了跟随事物的方法来解开高粱的多重身份,以及它在激励更健康的高粱方面可能发挥的作用,更多样化的食物系统。通过开放一种不限制研究人员的激进的跟随方法,与高粱相关的潜在故事被强调,这与作物所体现的多重潜力的感知转变相吻合。该研究强调,南非仍然存在与高粱的紧密文化联系,如果可以对创新进行广泛解释,这可能会激发对高粱的更丰富的参与,不仅仅是作为一种商品,但作为一种具有文化意义的食物。
    This paper follows sorghum, an indigenous, but currently underutilized, grain in South Africa, through six encounters to discover its potential to transform the country\'s food system. By listening to stories from diverse perspectives, it shows that the re-inclusion of sorghum could not only diversify diets, but could also move toward breaking colonial stereotypes of what constitutes aspirational food. It employs a Follow the Thing method to unpack the multiple identities of sorghum and the role it could play in galvanizing a healthier, more diverse food system. By opening up to a radical following method that does not constrain the researcher, the underlying stories associated with sorghum are highlighted, which coincides with a shift in perception of the multiple potentialities that the crop embodies. The research highlights that a strong cultural link to sorghum remains in South Africa and that if innovation could be broadly interpreted, this might invigorate a richer engagement with sorghum, not just as a commodity, but as a culturally significant food.

    饮食多样性是营养安全的基本因素之一,也是衡量饮食质量的指标。这项研究的目的是调查乡村鸡肉的可获得性与城乡梯度家庭饮食多样性之间的关系。在农村(n=100)使用结构化问卷进行了面对面的访谈,城市周边(n=100),和PietermaritzburguMgungundlovu区的城市(n=100)地区,夸祖鲁-纳塔尔省,在南非。观察到距市中心的距离与村庄鸡群大小之间存在正相关关系(p<0.001)。蔬菜的消费量随着距市中心距离的增加而增加(p<0.01)。观察到距市中心的距离与牲畜源性食品(LDF)的消费量之间存在二次关系(p<0.05)。LDF的消费量随着乡村鸡群规模的增加而增加(p<0.05)。蔬菜的消费量随着乡村鸡群大小的增加而增加(p<0.01)。食物种类评分(FVS)随着距市中心距离的增加而增加(p<0.05)。评估跨城乡梯度的乡村鸡的可用性是一个值得利用的机会,以改善家庭的饮食多样性和减轻贫困。可以得出结论,扩大村庄的羊群规模可以增强家庭的饮食多样性。
    Dietary diversity is one of the fundamental factors of nutritional security and a proxy used to measure diet quality. The objective of this study was to investigate the relationship between village chicken availability and the dietary diversity of households along a rural-urban gradient. Face-to-face interviews were conducted using a structured questionnaire in rural (n = 100), peri-urban (n = 100), and urban (n = 100) areas of Pietermaritzburg uMgungundlovu District, KwaZulu-Natal, in South Africa. A positive relationship between distance from the city center and village chicken flock sizes (p < 0.001) was observed. Consumption of vegetables increased with an increase in distance from the city center (p < 0.01). A quadratic relationship was observed between distance from the city center and consumption of livestock-derived foods (LDFs) (p < 0.05). Consumption of LDFs increased with an increase in village chicken flock sizes (p < 0.05). Consumption of vegetables increased with an increase in village chicken flock sizes (p < 0.01). Food variety score (FVS) increased with an increase in distance from the city center (p < 0.05). Assessing the availability of village chickens across rural-urban gradients is a worthy opportunity to utilize to improve households\' dietary diversity and alleviate poverty. It can be concluded that expanding village flock sizes could enhance the dietary diversity of households.

    我们吃的绝大部分食物来自于陆基农业,但是农业和食品技术的最新技术进步提供了使用少得多甚至几乎不使用土地生产食品的前景。例如,室内垂直耕作可以以非常小的面积足迹实现某些作物的非常高的产量,一些食品可以由工业设施中的无机前体合成。动物性食品每单位蛋白质或每卡路里需要大量土地,而转向替代品可能会减少对某些类型农业用地的需求。基于植物的肉类替代品和通过发酵生产的替代品是广泛可用的,并且变得更加复杂,而将来细胞农业可能在规模上在技术上和经济上变得可行。我们回顾了这些潜在颠覆性技术的现状,并探讨了它们如何与其他因素相互作用,食物系统的内源性和外源性,影响未来的土地需求。
    The vast majority of the food we eat comes from land-based agriculture, but recent technological advances in agriculture and food technology offer the prospect of producing food using substantially less or even virtually no land. For example, indoor vertical farming can achieve very high yields of certain crops with a very small area footprint, and some foods can be synthesized from inorganic precursors in industrial facilities. Animal-based foods require substantial land per unit of protein or per calorie and switching to alternatives could reduce demand for some types of agricultural land. Plant-based meat substitutes and those produced through fermentation are widely available and becoming more sophisticated while in the future cellular agricultural may become technically and economical viable at scale. We review the state of play of these potentially disruptive technologies and explore how they may interact with other factors, both endogenous and exogenous to the food system, to affect future demand for land.

    本研究调查了在COVID-19大流行的第一年,食品系统工作人员相对于其他人群的粮食不安全患病率和感知压力。它还探讨了粮食系统工作人员在大流行期间的作用以及他们在此期间的工作经验的观点。
    数据是通过2021年春季的在线调查收集的。样本由441名佛蒙特州居民组成,美国,包括41名食品系统工人。
    回归模型发现,在大流行的第一年,粮食系统工作人员的粮食不安全和感知压力的比率更高。然而,当模型根据收入和工作中断进行调整时,这些关系没有得到维持,这表明这些协会主要是由于粮食系统工人的经济脆弱性。大多数受访者表示关注食品系统工作人员的健康和福祉,认为食品系统的工作人员被低估了,并同意应优先考虑粮食系统工人的福祉。然而,对于要求农场和食品加工厂保持开放以维持食品供应是否值得健康风险,意见不一。一半的粮食系统工作人员认为他们的工作在大流行期间损害了他们的福祉,尽管一些人也认为他们的工作是获取食物的途径。
    这些发现为寻求提高食品供应和食品系统劳动力的弹性的决策者提供了有价值的信息。
    UNASSIGNED: The present study examined the prevalence of food insecurity and perceived stress among food system workers relative to other members of the population during the first year of the COVID-19 pandemic. It also explored perspectives on the role of food system workers during the pandemic and their experiences working during this time.
    UNASSIGNED: Data were collected via an online survey in spring 2021. The sample was comprised of 441 residents of Vermont, United States, including 41 food system workers.
    UNASSIGNED: Regression models identified higher rates of food insecurity and perceived stress among food system workers during the first year of the pandemic. However, these relationships were not maintained when the models were adjusted for income and job disruption, suggesting that the associations were primarily due to the economic vulnerability of food system workers. Most respondents indicated concern for the health and well-being of food system workers, felt that food system workers were undervalued, and agreed that the well-being of food system workers should be prioritized. However, opinions were split regarding whether it was worth the health risk to require farms and food processing plants to stay open to maintain the food supply. Half of food system workers believed that their work had compromised their well-being during the pandemic, although several also identified their jobs as pathways for accessing food.
    UNASSIGNED: The findings provide valuable information for decision-makers seeking to increase the resilience of the food supply and the food system workforce.

    肥胖从根本上说是个体的生理和行为与环境相遇的一种状况,新兴的全球肥胖大流行反映了广泛的文化,社会,经济和系统驱动力。今天,肥胖研究的不同领域在离散的孤岛中相对分离,生物医学研究决定了我们的大部分理解和解决方案策略。这导致了Y在路上,这意味着一个值得怀疑的假设,即对个体患者进行有效的药物治疗也是改善人群健康的有效措施。由于人类肥胖是人口健康和行星影响的条件,因此生物医学和公共卫生方法的更好整合是基于对来自各个研究领域的科学家的批判性(自我)反思和交流理解,他们应该处于平等的地位。
    Obesity is fundamentally a condition where physiology and behavior of individuals meet the environment, and the emerging global obesity pandemic reflects the contribution of a wide range of cultural, societal, economic and systemic driving forces. Today, different areas of obesity research are relatively separated from each other in discrete silos, with biomedical research determining most of our understanding and solution strategies. This has led to the Y in the road, which means the questionable assumption that effective drug treatment of individual patients is also an effective measure to improve population health. Since human obesity is a condition of population health and planetary impact a better integration of biomedical and public health approaches is based on critical (self-)reflection and communicative understanding of scientists from various research areas who should be on an equal footing.

    世界目前正处于全球粮食危机之中,这是由一系列相互促进的粮食系统冲击带来和加剧的。这项研究调查了六个亚洲国家(孟加拉国,吉尔吉斯共和国,老挝,巴基斯坦,菲律宾,和斯里兰卡)在COVID-19、地缘政治冲突造成的全球“多重危机”中,和气候变化。对来自全球数据库和世界粮食计划署国家数据的19项指标进行了趋势分析,代表食物系统弹性的四个领域:暴露于冲击;弹性能力以及农业和食物多样性,弹性反应和策略;以及长期弹性结果。分析显示,所有六个国家都经历了“多危机”的影响,导致对汇率的不同影响,斯里兰卡,巴基斯坦,老挝人民民主共和国面临大幅货币贬值。虽然大多数国家在危机期间增加了作物产量,减少了粮食进口,大流行期间政府的经济支持差异很大。弹性结果,包括国家食品价格上涨和面临粮食不安全的人口比例,见证了向上的变化。总的来说,在“多危机”开始时具有较高抵御能力的国家显示出不那么严重的长期抵御能力结果。我们的调查结果强调了每个国家面临的各种挑战和抵御能力,受复杂的经济相互作用的影响,政治,农业,和食品可负担性因素对于确定其食品系统的长期韧性至关重要。未来研究的建议包括关注食物系统的弹性评估,整合气候变化适应措施,并制定早期干预策略。
    The world is currently in the midst of a global food crisis brought about and exacerbated by a series of mutually reinforcing shocks to food systems This study investigated the resilience of food systems in six Asian countries (Bangladesh, Kyrgyz Republic, Lao PDR, Pakistan, Philippines, and Sri Lanka) amidst the global \'polycrisis\' caused by COVID-19, geopolitical conflicts, and climate change. Trend analyses were performed for 19 indicators sourced from global databases and World Food Programme national data, representing the four domains of food system resilience: exposure to shocks; resilience capacities and agro- and food diversity, resilience responses and strategies; and long-term resilience outcomes. The analysis revealed that all six countries experienced the effects of the \'polycrisis\', leading to diverse impacts on exchange rates, with Sri Lanka, Pakistan, and Lao PDR facing significant currency depreciation. While most countries increased crop production and decreased food imports during the crisis, government economic support during the pandemic varied widely. Resilience outcomes, including national food price inflation and the proportion of populations facing food insecurity, witnessed upward variations. Overall, countries with higher resilience capacities at the start of the \'polycrisis\' showed less severe long-term resilience outcomes. Our findings highlight the varied challenges and resilience capacities across each country, influenced by a complex interplay of economic, political, agricultural, and food affordability factors crucial for determining long-term resilience in their food systems. Recommendations for future research include focusing on resilience assessment in food systems, integrating climate change adaptation measures, and developing early intervention strategies.
