Severe food insecurity (SFI) is a critical concern in India, yet few studies have highlighted national and state trends among Indian adults. Utilizing data from 63,525 adults aged 45 and above from the Longitudinal Aging Study in India (2017-18), we present noteworthy geographic and sociodemographic patterns in the distribution of SFI. We estimate the national prevalence to be 6.2% (95% CI: 5.6, 6.8). Madhya Pradesh had the highest prevalence of SFI (10.3%), followed by Jharkhand, Tamil Nadu, and Bihar. Conversely, Nagaland, Goa, Lakshadweep, and Arunachal Pradesh had the lowest prevalence (all under 2.0%). Living in a rural area, being widowed, belonging to a Scheduled Caste, and being Muslim were positively associated with reporting SFI. Additionally, those in the middle and richer household monthly per capita expenditure quintiles, with 6–9 years of schooling, who resided in the country's northern and northeastern regions, or who had never worked for more than three months in their lifetime, were less likely to report SFI. We also find that geography and socioeconomic status synergistically affect SFI. Specifically, adults with lower levels of education were at a greater risk of SFI in rural areas, relative to urban areas, and the Central and East regions of India, relative to the North. Our findings highlight the need for robust state-level policies to ensure equitable access to affordable, high-quality food for all Indian adults, particularly for those belonging to at-risk groups.
严重的粮食不安全(SFI)是印度的一个重要问题,但很少有研究突出了印度成年人的国家和州趋势。利用来自印度纵向老龄化研究(2017-18)的63,525名45岁及以上成年人的数据,我们展示了SFI分布中值得注意的地理和社会人口模式。我们估计全国患病率为6.2% (95% CI: 5.6, 6.8)。中央邦的SFI患病率最高(10.3%),其次是贾坎德邦、泰米尔纳德邦和比哈尔邦。相反,那加兰邦、果阿邦、拉克沙德邦和**的患病率最低(均低于2.0%)。生活在农村地区、丧偶、属于既定种姓和穆斯林与报告SFI呈正相关。此外,那些中等和较富裕家庭的月人均支出五分之一,受过6-9年教育,居住在该国北部和东北部地区,或一生中从未工作超过三个月的人,报告SFI的可能性较小。我们还发现地理和社会经济地位对SFI有协同影响。具体来说,教育水平较低的成年人在农村地区相对于城市地区,在印度中部和东部地区相对于北部地区,有更大的SFI风险。我们的研究结果强调,需要制定强有力的州一级政策,以确保所有印度成年人,特别是那些属于高危群体的成年人,公平地获得负担得起的高质量食物。

The unsustainable nature of prevailing food systems contributes to drive humanity out of a safe operating space. Despite recognising the need for food systems transformation, its direction diverges into different sustainability narratives and conflicting objectives resulting in disjoint policy agendas and problem definitions. While few studies compared and identified gaps and trade-offs in food systems frameworks, systematic reviews for conceptualising sustainable food systems remain scarce. Focusing on the European context, we investigated how academics framed sustainability narratives and their role in advancing Sustainable Development Goals targets, exploring lock-ins and leverage points for food system transformation. By conducting a PRISMA systematic scoping review and analysing 94 documents, we found disparities in current research with socio-economic and cross-cutting aspects comparatively overlooked to environmental and health ones. Linking sustainability objectives to 55 SDG targets we demonstrated their potential contributions to sustainable development by addressing systemic conceptualisations and acknowledging trade-offs. We identified lack of vision and coordination among stakeholders and institutional framework shortcomings as barriers to change. Analysis of leverage points suggested stakeholder engagement and system transparency as pivotal for transformation. Last, we draw concrete implications for science and policy agendas to shape a food systems transformation grounded in a shared sustainability paradigm forged through collaborative efforts among scientific, policy, and societal domains.
现行粮食系统的不可持续性导致人类被赶出安全的生存空间。尽管认识到粮食系统转型的必要性,但其方向分歧为不同的可持续性叙述和相互冲突的目标,导致政策议程和问题定义脱节。虽然很少有研究比较和确定粮食系统框架中的差距和权衡,但对可持续粮食系统概念化的系统审查仍然很少。以欧洲为重点,我们调查了学者如何构建可持续发展叙事及其在推进可持续发展目标目标中的作用,探讨了粮食系统转型的锁定和杠杆点。通过对prism系统范围审查和分析94份文件,我们发现,与环境和健康方面相比,目前研究中的社会经济和跨领域方面存在差异。我们将可持续发展目标与55个可持续发展目标联系起来,通过解决系统概念和承认权衡,展示了它们对可持续发展的潜在贡献。我们认为,利益相关者之间缺乏远见和协调,体制框架的缺陷是变革的障碍。对杠杆点的分析表明,利益相关者参与和系统透明度是转型的关键。最后,我们得出了科学和政策议程的具体含义,以塑造通过科学,政策和社会领域之间的合作努力形成的共享可持续性范式为基础的粮食系统转型。

The extent to which the food supply aligns with the food and nutrition demand is unclear, which is crucial during crises like the COVID pandemic. Here, we present a geospatial framework integrating 3.8 million road segments for evaluating the food system resilience in alignment with Chinese dietary requirements. Results reveal that China faces challenges in achieving complete local self-sufficiency in specific foods and heavily relies on large-scale transport in a north-south direction. When comparing actual consumption to the ideal dietary requirements, there is average increased pressure of 6.1% in food transport intensity (i.e., from 0.6% in staples to 11% in oilseeds). Nevertheless, China's diverse food supply chain is rich, and the food system in the southeastern coastal cities (46% of all) is highly resilient, but resilience decreases from east to west. In the future, policymakers should prioritize local food distribution by building a centrally coordinated-locally autonomous supply and marketing network.
粮食供应与粮食和营养需求的一致程度尚不清楚,这在COVID大流行等危机期间至关重要。在这里,我们提出了一个地理空间框架,整合了380万个路段,用于评估符合中国饮食要求的粮食系统弹性。结果表明,中国在实现特定食品的完全自给自足方面面临挑战,并且严重依赖南北方向的大规模运输。当将实际消费量与理想膳食需求进行比较时,粮食运输强度的压力平均增加了6.1%(即,从主食的0.6%增加到油籽的11%)。尽管如此,中国多样化的食品供应链是丰富的,东南沿海城市(占全部城市的46%)的食品系统具有很强的弹性,但弹性从东向西递减。未来,政策制定者应该通过建立一个中央协调的地方自治供销网络,优先考虑地方粮食分配。

The war that broke out between Russia and Ukraine in February 2022 has left many countries facing difficult challenges, one of which has been the escalation of global food security issues. This study examines how the conditions of war negatively reflect on food security and how social media posts collected from different countries around the world were used to categorize and examine societal concerns following the war. Concerns and reasons were analyzed based on countries using an aspect-based sentiment analysis using a sentiment classifier with the BERT architecture. In Africa and the Middle East, societal concerns are centered around the possibility of not accessing food and potential famine; other analyses conducted in these countries indicate that access to products such as bread, baby food, animal products (milk, cheese, etc.), pasta, and many other categories have become significantly challenging. A large portion of the world views the food security crisis caused by the war as potentially leading to economic problems and famine. Social media posts from Poland, especially, in Central and Eastern European countries are intensely focused on economic issues. The sentiment analysis studies show that the Black Sea Grain Initiative, aimed at securing food security between the two countries, increased positive sentiments globally by up to 24%. To the best of our knowledge, this study is the first to identify concerns stated at the societal level worldwide on food security and measure objectives by country. This study presents findings that can develop projections for assessing concerns reflected in society regarding food security and formulating alternative plans, contributing to many countries in this regard.
俄罗斯和乌克兰于2022年2月爆发的战争使许多国家面临严峻挑战,其中之一就是全球粮食安全问题的升级。本研究考察了战争条件如何对粮食安全产生负面影响,以及如何使用从世界各地不同国家收集的社交媒体帖子来对战争后的社会问题进行分类和检查。使用基于方面的情感分析,使用带有BERT架构的情感分类器,基于国家分析了关注点和原因。在非洲和中东,社会关注的焦点集中在无法获得食物和潜在饥荒的可能性上;在这些国家进行的其他分析表明,获得面包、婴儿食品、动物产品(牛奶、奶酪等)、面食和许多其他类别的产品已变得非常困难。世界上很大一部分人认为,战争造成的粮食安全危机可能导致经济问题和饥荒。来自波兰,特别是中欧和东欧国家的社交媒体帖子强烈关注经济问题。情绪分析研究表明,旨在确保两国粮食安全的黑海粮食倡议在全球范围内增加了24%的积极情绪。据我们所知,这项研究首次确定了全球社会层面对粮食安全和各国措施目标的关注。这项研究提出的结果可以预测社会对粮食安全的关注,并制定替代计划,在这方面对许多国家有所帮助。

Globally, food production and food systems can harm ecosystems by depleting resources and creating imbalances in food webs. Over 148 million young children around the world are chronically malnourished, with disproportionate numbers coming from small-scale food producing households. Here we show in a community-based trial in coastal Kenya that child nutrition and the availability of sustainably harvested fish were improved through an integrated strategy. This longitudinal, cluster-designed study compared outcomes across groups: 1) control (n = 200 households, 41 fisher trips); 2) social marketing for behavior change among caregivers and fishers (n = 100 households, 118 fisher trips); and 3) social marketing plus modified fishing gear (traps with gaps for juveniles to escape; n = 100 households, 73 fisher trips). Child growth in stature (height-for-age Z score) was significantly increased in the intervention arms relative to control, supported by findings for increased dietary diversity, child fish consumption, and take-home catch (kg). Fish were significantly longer (cm) in arm 3 (social marketing plus modified traps) relative to arm 2 (social marketing), leading to increased nutrients from fish available for consumption. This study advances public health and fisheries disciplines by demonstrating that human and environmental health may be simultaneously achieved through context-responsive, integrated strategies.
在全球范围内,粮食生产和粮食系统会耗尽资源,造成粮食网失衡,从而损害生态系统。全世界有超过1.48亿幼儿长期营养不良,其中不成比例的儿童来自小规模粮食生产家庭。我们在肯尼亚沿海地区进行的一项社区试验表明,通过一项综合战略,儿童营养和可持续捕捞鱼类的可得性得到了改善。这项纵向、聚类设计的研究比较了各组的结果:1)对照组(n = 200户,41次捕鱼旅行);2)社会营销对照顾者和渔民行为改变的影响(n = 100户,118次渔次);3)社会营销+改良渔具(有空隙的陷阱,供未成年人逃脱);N = 100户,73次捕鱼行程)。与对照组相比,干预组的儿童身高增长(年龄比身高Z分)显著增加,饮食多样性、儿童鱼类消费量和带回家渔获量(公斤)的增加也支持了这一发现。相对于第2组(社会营销),第3组(社会营销加改良陷阱)中的鱼明显更长(厘米),导致可食用鱼的营养成分增加。这项研究表明,人类健康和环境健康可以通过因地制宜的综合战略同时实现,从而推动了公共卫生和渔业学科的发展。

This paper examines the shifts needed in the development, adoption and scaling of innovation and technology to achieve resilient and inclusive rural transformation across farming systems and value chains. It analyzes opportunities for innovations to generate rural employment, improve smallholder farmer livelihoods, alleviate malnutrition and address the impacts of climate change. The paper identifies five key levers of change that include: (i) a renewed focus on long-term investment in participatory, equity-sensitive and gender-responsive agricultural R&D, (ii) ensuring that marginalized voices are heard, (iii) promoting equitable access to technology, (iv) leveling the playing field by curbing corporate dominance while encouraging private sector support for small- and medium-scale agrifood enterprises, and (v) prioritizing rural employment amid automation and evolving value chains.

Sufficient food is available in the world for all people to consume sufficient calories, but not healthy diets. This study traces historical and projected changes in global food systems toward alignment with the new Healthy Diet Basket (HDB) used by UN agencies and the World Bank to monitor the cost and affordability of healthy diets worldwide. Using the HDB as a standard to measure adequacy of national, regional and global supply-demand balances, we find substantial but inconsistent progress toward closer alignment with dietary guidelines, with large global shortfalls in fruits, vegetables, and legumes, nuts, and seeds, and large disparities among regions in use of animal source foods. Projections show that additional investments aimed at reducing chronic hunger would modestly accelerate improvements in adequacy where shortfalls are greatest, revealing the need for complementary investments to increase access to under-consumed food groups especially in low-income countries.
世界上有足够的食物供所有人消耗足够的卡路里,但没有健康的饮食。本研究追踪了全球粮食系统的历史变化和预测变化,以与联合国机构和世界银行用于监测全球健康饮食成本和可负担性的新健康饮食篮子(HDB)保持一致。使用组数据作为衡量国家、地区和全球供需平衡是否充足的标准,我们发现在更接近膳食指南方面取得了实质性但不一致的进展,全球水果、蔬菜、豆类、坚果和种子的供应严重不足,各地区在动物源食品的使用方面存在巨大差异。预测显示,旨在减少长期饥饿的额外投资将略微加速粮食短缺最严重地区充足性的改善,这表明需要进行补充性投资,以增加获得消费不足粮食群体的机会,特别是在低收入国家。

The burgeoning frequency and intensity of varied global exogenous shocks such as climate variability, economic slowdowns, conflicts, scarcity, changing demand pattern, loss of Agricultural land, new age diseases etc have undermined the food security and diets around the world. There is a growing consensus of nutrition transition paving its way towards convergence of global diets. Our study aims to investigate the significant changes in the global dietary pattern with the plausible reasons for the underlying changes. We analysed data for 14 Agri-commodities across 171 countries for a period of 63 years (1960–2023) from the Pink Sheet of World Bank Commodity details. We have divided the time period into six sub-samples each a decade apart. We have employed the Time Varying VAR method to study the frequency of shock emitting events to determine the significant dietary changes. Our results suggest the periodicity in shock emitting pattern of the Agri-commodities. All the sub-samples exhibit extreme spillover effect throughout. This underscores the fundamental vulnerability of the Agri-commodities, as far too many uncorrelated events impact the Agri-commodity ecosystem. The results highlight the importance of the ‘3R Strategy’ (suggested by the University of Oxford) consisting resist, recover & reorient for achieving stability in the overall food systems against climate change (region wise & for some cases country specific) as well as the measures of sustainable intensification to ensure soil efficiency and economic viability simultaneously. We found, Indonesia (an exporter of Palm Oil) and Brazil (an exporter of Groundnut Oil & Chicken) have reoriented themselves, whereas China (for Groundnut Oil), India (for Palm Oil) & Sub-Saharan Africa (for Chicken) have resisted the changes and on path of recovery. The pattern of dominating Agri commodities is evident, as the exporters are ‘reorienting’ whereas the importers are ‘resisting & recovering’.
气候变化、经济放缓、冲突、短缺、需求模式变化、农业用地丧失、新时代疾病等各种全球外生冲击的频率和强度不断增加,破坏了世界各地的粮食安全和饮食。关于营养转型的共识越来越多,这为全球饮食的趋同铺平了道路。我们的研究旨在探讨全球饮食模式的重大变化及其潜在变化的合理原因。我们分析了世界银行大宗商品详细信息粉红单中171个国家63年(1960-2023年)的14种农业大宗商品数据。我们把这段时间分成六个子样本,每隔十年。我们采用时变VAR方法来研究冲击事件发生的频率,以确定显著的饮食变化。我们的研究结果表明,农产品的冲击释放模式具有周期性。所有子样本都表现出极端的溢出效应。这凸显了农产品的根本脆弱性,因为有太多不相关的事件影响着农产品生态系统。研究结果强调了“3R战略”(由牛津大学提出)的重要性,包括抵抗、恢复和恢复。重新定位,以实现整个粮食系统的稳定,以应对气候变化(区域范围);在某些情况下(具体国家)以及可持续集约化措施,以同时确保土壤效率和经济可行性。我们发现,印度尼西亚(棕榈油出口国)和巴西(花生油出口国);鸡肉)已经重新定位了自己,而中国(花生油),印度(棕榈油)撒哈拉以南非洲(鸡)抵制了这些变化,走上了复苏之路。主导农产品的模式很明显,因为出口商正在“重新定位”,而进口商正在“抵制”。恢复”。

Armed conflict and gendered participation in agrifood systems: Survey evidence from 29 African countries 农业粮食系统中的武装冲突和性别参与:来自29个非洲国家的调查证据

This paper provides empirical micro-level evidence on the gendered impacts of armed conflict on economic activity in agriculture and other sectors, combining large-N sex-disaggregated survey data with temporally and spatially disaggregated conflict event data from 29 African countries. We find that local conflict exposure is only weakly related to labour-force participation, but strongly reduces the total number of hours worked and increases engagement in the agricultural sector. These net impacts exist for both men and women. However, the reduction in hours worked is significantly greater among men, while the increase in agricultural activity is significantly greater among women. In the longer term, impacts of conflict on employment two years later are stronger when no more conflict ensues than if further conflict occurs, challenging the widespread idea of one-off conflict shocks fading away over time and suggesting that labour markets adapt to and absorb lasting conflict situations. Different types of conflict event have qualitatively similar impacts, which are strongest for explosions, such as from air strikes or landmines. Overall, our findings underline that armed conflict entails structural economic, social and institutional change, which creates complex, gendered impacts on economic activity.
本文结合来自29个非洲国家的按性别分列的大n调查数据和按时间和空间分列的冲突事件数据,为武装冲突对农业和其他部门经济活动的性别影响提供了微观层面的实证证据。我们发现,当地冲突暴露与劳动力参与的关系很弱,但却大大减少了总工作时间,增加了农业部门的参与度。这些净影响对男性和女性都存在。但是,男性工作时数减少的幅度要大得多,而女性农业活动增加的幅度要大得多。从长期来看,两年后冲突不再发生时,冲突对就业的影响比发生进一步冲突时更大,这挑战了一次性冲突冲击随着时间的推移而消失的普遍观点,并表明劳动力市场适应和吸收持久的冲突局势。不同类型的冲突事件在性质上具有相似的影响,其中爆炸(如空袭或地雷)的影响最大。总体而言,我们的研究结果强调,武装冲突导致结构性经济、社会和制度变革,从而对经济活动产生复杂的性别影响。

Rural transformation pathways focused on efficiency and productivity often leave women and marginalized social groups behind in addition to having negative impacts on the environment and nutrition. As rural transformation models are reconsidered from an agrifood-system perspective to include climate change and nutrition goals, it is also critical to reevaluate how gender and intersecting dimensions of power are integrated. Shifting the focus from 'what' to 'how', the study asserts that meaningful synergies are present among decent livelihoods, climate action, and nutrition – key domains of resilient and inclusive rural transformation – and women's empowerment. It identifies five critical pathways that are relevant across the three domains to position gender at the center of resilient and inclusive rural transformation and underscores the importance of quality data and increased finance to enact these pathways.
注重效率和生产力的农村转型途径除了对环境和营养产生负面影响外,往往将妇女和边缘化社会群体抛在后面。在从农业粮食系统的角度重新考虑农村转型模式以包括气候变化和营养目标的同时,重新评估如何整合性别和权力的交叉维度也至关重要。该研究将重点从“做什么”转移到“如何做”,并断言,体面生计、气候行动和营养(韧性和包容性农村转型的关键领域)与妇女赋权之间存在有意义的协同效应。报告确定了与这三个领域相关的五条关键途径,将性别置于有复原力和包容性的农村转型的中心,并强调了高质量数据和增加资金对实施这些途径的重要性。
