粮食安全
  • 文章类型: Journal Article
    粮食安全是当前世界发展进程中的重要问题之一。文章以我国31个省(区、市)为研究对象,从定量安全、营养安全,生态安全,和容量安全。使用熵方法,计算了2013年至2022年十年的中国粮食安全指数。总的来说,中国的粮食安全水平在这十年中呈上升趋势,与山东各省,黑龙江,河南的安全级别最高。利用Dagum基尼系数及其分解,考察了七个地区粮食安全的分布动态及其时空演变,验证了不同地区粮食安全的绝对趋同和条件趋同。研究结果表明,华东地区各省之间的粮食安全水平差距最大,并且存在绝对β收敛。把中国作为一个整体来看,其粮食安全水平的发展具有显著的趋同特征,这意味着粮食安全水平低的省份将比粮食安全水平高的省份有更快的增长速度,导致各省之间粮食安全水平的差距逐步缩小。
    Food security is one of the important issues in the current world development process. The article takes 31 provinces (districts and cities) in China as the research object and constructs a multidimensional food security level evaluation index system from four dimensions: quantitative security, nutritional security, ecological security, and capacity security. Using the entropy method, China\'s food security index was calculated for the ten-year period from 2013 to 2022. Overall, China\'s food security level showed an upward trend during the decade, with the provinces of Shandong, Heilongjiang, and Henan having the highest level of security. The distribution dynamics of food security and its spatiotemporal evolution in the seven regions were examined using the Dagum Gini coefficient and its decomposition, and the absolute and conditional convergence of food security in the different areas was verified. The results of the study show that the provinces within East China have the largest gap in food security levels between them, and there is absolute β-convergence. Looking at China as a whole, the development of its food security level is characterized by significant convergence, which means that provinces with a low level of food security will have a faster rate of growth than those with a high level of food security, resulting in a gradual narrowing of the gap in food security levels between provinces.

    Resistant starch (RS) is a dietary fiber that resists starch hydrolysis in the small intestine, and is fermented in the colon by microorganisms. RS not only has a broad range of benefits in the food and non-food industries but also has a significance impact on health promotion and prevention of non-communicable diseases. RS types 3 and 5 have been the focus of research from an environment-friendly perspective. RS3 is normally formed by recrystallization after physical modification, whereas RS5 is obtained by the complexation of starch and fatty acids through the thermomechanical methods. This review provides updates and approaches to RS3 and RS5 preparations that promote RS content based on green technologies. This information will be useful for future research on RS development and for identifying preparation methods for functional food.

    农业劳动力向非农部门的转移与中国经济发展同步,导致劳动力成本相对于资本的大幅上升。因此,农业生产已经向资本密集型做法转变。资本深化与中国粮食产量的大幅增加相吻合,而中国粮食产量中资本深化的主要原因却知之甚少。本研究考察了各种资本投资的增加对中国主产区粮食产量增长和增长收敛的影响。基于从农产品成本效益数据汇编(CCBDAP)数据集中收集的数据。结果表明,化肥用量的增加,农药和机械投入对粮食增产起到了关键作用。对于早稻,粳稻,小麦和玉米,平均土地产出具有β收敛。这些发现表明,更多的资本投资应该加速单位土地粮食产量的增长,以实行耕地占补跨省均衡制度为契机。此外,建议对粮食种植空间分布进行战略调整,以最大限度地利用有限的耕地资源,同时坚持国家粮食安全目标。
    The shift of agricultural labor force to non-agricultural sectors has paralleled China\'s economic development, leading to a substantial rise in labor costs relative to capital. Consequently, the agricultural production has witnessed a shift towards capital-intensive practices. The capital deepening coincides with the significant increase in China\'s grain output while the main cause of capital deepening in China\'s grain production is poorly understood. This study examines the effect of increasing in various capital investments on the grain yield growth and growth convergence in China\'s main production areas, based on the data collected from the data set of the Compilation of Cost-Benefit Data of Agricultural Products (CCBDAP). Results show that the increases of chemical fertilizer, pesticide and machinery input have played key roles in the increase of grain yield. For early indica rice, japonica rice, wheat and maize, the average land output bears a β convergence. These findings suggest that more capital investments are supposed to accelerate the growth of grain yield per unit of land, take the opportunity of practicing the cross-provincial balance system of occupation and compensation of cultivated land. Moreover, strategic adjustments to the spatial distribution of grain cultivation are recommended to maximize the utilization of limited arable land resources while upholding national food security objectives.

    米粒被广泛用作主食,为家庭提供必要的营养,尤其是边缘化家庭。它在确保粮食安全方面发挥着至关重要的作用,促进人类营养,支持良好的健康,促进全球粮食和营养安全。为了解决新兴的多样化和气候风险人群饮食需求的多样化质量需求,需要开发能够满足各种饮食和营养需求的单一品种稻米。然而,稻米品质缺乏具体定义,使它具有挑战性,以满足不同的需求。在改善稻米品质方面缺乏足够的遗传研究和开发,导致普遍营养不良,隐藏的饥饿,和微量营养素缺乏影响全球人口的很大一部分。因此,至关重要的是,确定具有显著品质的基因进化品种,可以帮助解决这些问题。各种因素导致稻米品质下降,需要进一步研究以提高其品质,以获得更健康的饮食。我们使用Lancastrians描述符和许多内在和外在品质性状表征了稻米的品质。接下来,我们研究了亚太地区稻米品质的各种成分。这包括不同社区的偏好,水稻产业利益相关者,和价值链参与者。我们还探索了该地区稻米品质的生物学方面,以及在这些特征中进行的特定遗传改进。此外,我们评估了影响稻米品质的因素,并讨论了确保粮食和营养安全以及满足消费者对谷物品质需求的未来方向。我们探索了包括印度在内的亚太国家不同的消费者基础和他们不同的偏好,中国,尼泊尔,不丹,越南,斯里兰卡,巴基斯坦,泰国,柬埔寨,菲律宾,孟加拉国,印度尼西亚,韩国,缅甸和日本。质量偏好包含一系列因素,包括米头恢复,颗粒形状,烹饪前的均匀尺寸,糊化,白垩,纹理,直链淀粉含量,香气,谷物的红色,煮熟时柔软闪亮,煮熟时不间断,糊化,做饭需要更少的水,糊化温度(较少的烹饪时间),陈年大米,煮熟时坚硬干燥(凝胶稠度),极端的白色,咀嚼时柔软,易于烹饪的米饭(煮米饭),维生素,和矿物。这些偏好被评估得很高,低,中等类别。对提高籽粒品质性状进行了综合分析,包括糙米的恢复,精米的回收率,头部大米恢复,以及粒长等形态特征,晶粒宽度,晶粒长宽比,和谷物白垩。我们还探索了直链淀粉的特性,凝胶稠度,糊化温度,粘度,以及米粒的营养品质,如淀粉,蛋白质,脂质,维生素,矿物,植物化学物质,和生物强化潜力。影响米粒品质的各种因素,包括收获前,收获后,和基因型考虑因素进行了探讨。此外,我们讨论了有效应对这些挑战的未来方向和遗传策略。这些定性特征代表了不同国家为满足消费者偏好而采用的区域和国家育种策略的基本重点。鉴于大米作为亚太国家主食的重要性,它主要在国内消费,只有一小部分出口到国际上。所有重要的属性必须在特定参数中明确定义。对于遗传学家和育种者来说,开发一种水稻品种至关重要,该品种可以通过结合多种理想性状来满足全球消费者的多种需求。因此,解决全球粮食和营养安全的目标,人类的健康是可以实现的。
    Rice grain is widely consumed as a staple food, providing essential nutrition for households, particularly marginalized families. It plays a crucial role in ensuring food security, promoting human nutrition, supporting good health, and contributing to global food and nutritional security. Addressing the diverse quality demands of emerging diverse and climate-risked population dietary needs requires the development of a single variety of rice grain that can meet the various dietary and nutritional requirements. However, there is a lack of concrete definition for rice grain quality, making it challenging to cater to the different demands. The lack of sufficient genetic study and development in improving rice grain quality has resulted in widespread malnutrition, hidden hunger, and micronutrient deficiencies affecting a significant portion of the global population. Therefore, it is crucial to identify genetically evolved varieties with marked qualities that can help address these issues. Various factors account for the declining quality of rice grain and requires further study to improve their quality for healthier diets. We characterized rice grain quality using Lancastrians descriptor and a multitude of intrinsic and extrinsic quality traits. Next, we examined various components of rice grain quality favored in the Asia-Pacific region. This includes preferences by different communities, rice industry stakeholders, and value chain actors. We also explored the biological aspects of rice grain quality in the region, as well as specific genetic improvements that have been made in these traits. Additionally, we evaluated the factors that can influence rice grain quality and discussed the future directions for ensuring food and nutritional security and meeting consumer demands for grain quality. We explored the diverse consumer bases and their varied preferences in Asian-Pacific countries including India, China, Nepal, Bhutan, Vietnam, Sri Lanka, Pakistan, Thailand, Cambodia, Philippines, Bangladesh, Indonesia, Korea, Myanmar and Japan. The quality preferences encompassed a range of factors, including rice head recovery, grain shape, uniform size before cooking, gelatinization, chalkiness, texture, amylose content, aroma, red-coloration of grain, soft and shine when cooked, unbroken when cooked, gelatinization, less water required for cooking, gelatinization temperature (less cooking time), aged rice, firm and dry when cooked (gel consistency), extreme white, soft when chewed, easy-to-cook rice (parboiled rice), vitamins, and minerals. These preferences were evaluated across high, low, and medium categories. A comprehensive analysis is provided on the enhancement of grain quality traits, including brown rice recovery, recovery rate of milled rice, head rice recovery, as well as morphological traits such as grain length, grain width, grain length-width ratio, and grain chalkiness. We also explored the characteristics of amylose, gel consistency, gelatinization temperature, viscosity, as well as the nutritional qualities of rice grains such as starch, protein, lipids, vitamins, minerals, phytochemicals, and bio-fortification potential. The various factors that impact the quality of rice grains, including pre-harvest, post-harvest, and genotype considerations were explored. Additionally, we discussed the future direction and genetic strategies to effectively tackle these challenges. These qualitative characteristics represent the fundamental focus of regional and national breeding strategies employed by different countries to meet consumer preference. Given the significance of rice as a staple food in Asia-Pacific countries, it is primarily consumed domestically, with only a small portion being exported internationally. All the important attributes must be clearly defined within specific parameters. It is crucial for geneticists and breeders to develop a rice variety that can meet the diverse demands of consumers worldwide by incorporating multiple desirable traits. Thus, the goal of addressing global food and nutritional security, and human healthy can be achieved.

    目标:粮食安全在实现可持续发展目标2(SDG-2)和公共卫生成果方面发挥着关键作用;然而,在国际制裁的影响下,其有效性仍不清楚。这项研究考察了国际制裁对实现可持续发展目标2和粮食安全的影响。
    方法:这项跨国实证分析基于一个组合数据库,其中包括来自全球制裁数据库(GSDB)的数据,粮食及农业组织统计(FAOSTAT)和联合国(UN)商品贸易统计。
    方法:首先,使用工具变量(IV)策略来处理目标国家制裁中其他事件的内生性。第二,使用高维固定效应进行两阶段最小二乘(2SLS)回归.第三,基于结构重力模型,对双边农产品贸易进行了泊松伪最大似然(PPML)回归。
    结果:这项研究的结果表明,国际制裁对实现SDG-2和粮食安全产生了负面影响,这与不良的公共卫生结果有关。这主要表现在营养不足的患病率增加和中度或重度发育迟缓的儿童人口众多。制裁也被证明扭曲了农业增值份额,减少了国内农业生产。此外,制裁阻碍了双边进口供应,导致进口价值和数量下降,和更高的进口价格。
    结论:与饥饿相关的粮食安全和农业可持续性,从1950年到2019年,营养和健康与国际制裁密切相关。在国际制裁的不确定冲击下,实现SDG-2的进展恶化,主要针对目标2.1、2.2和2。a,所有目标的影响都不一致。从社会政治的角度来看,本研究的实证结果为政策制定者和公共卫生界增加人道主义外展提供了重要的经验教训.
    OBJECTIVE: Food security plays a critical role in achieving Sustainable Development Goal 2 (SDG-2) and public health outcomes; however, its effectiveness under the impact of international sanctions remains unclear. This study examined the impact of international sanctions on achieving SDG-2 and food security.
    METHODS: This cross-country empirical analysis was based on a combined database that included data from the Global Sanctions Data Base (GSDB), Food and Agriculture Organization Statistics (FAOSTAT) and United Nations (UN) Comtrade.
    METHODS: First, an instrumental variable (IV) strategy was used to deal with the endogeneity of other events in target countries\' sanctions. Second, a two-stage least square (2SLS) regression was conducted using high-dimensional fixed effects. Third, based on the Structural Gravity Model, a Poisson pseudo maximum likelihood (PPML) regression on bilateral agricultural trade was performed.
    RESULTS: Findings from this study showed that international sanctions had a negative impact on the achievement of SDG-2 and food security, which was associated with poor public health outcomes. This was mainly evidenced by an increase in the prevalence of undernourishment and a high population of children with moderate or severe stunting. Sanctions were also shown to distort the agricultural value-added share and decrease domestic agricultural production. In addition, sanctions impeded bilateral import supply, which resulted in a lower import value and quantity, and a higher import price.
    CONCLUSIONS: Food security and agricultural sustainability associated with hunger, nutrition and health from 1950 to 2019 were significantly associated with international sanctions. Under the uncertain shock of international sanctions, progress towards SDG-2 deteriorated, mainly for Targets 2.1, 2.2 and 2.a, and the impact was non uniform across all targets. From a sociopolitical perspective, the empirical findings of this study provide vital lessons for policymakers and public health communities to increase humanitarian outreach.

    在21世纪,随着全球化的加速和全球公共卫生危机的发生,一个健康的方法,以人类-动物-环境的整体思维为指导,强调跨学科合作以解决全球健康问题,得到了国际社会的大力倡导。迫切需要创建评估工具,以促进全球和国家范围的“一个健康”倡议。
    建立在广泛的专家咨询和对话的基础上,这项后续研究增强了2022年全球一个健康指数(GOHI)指标体系。GOHI框架涵盖了三个指数,例如,外部驱动程序索引(EDI),内在驱动因素指数(IDI),和核心驱动因素指数(CDI)。综合指标体系纳入了13项关键指标,50个指标,和170个子I指标,利用模糊层次分析法确定各指标的权重。加权和求和,EDI,IDI,和CDI分数有助于计算GOHI2022总得分。通过比较七个地区和160个国家/地区的排名和总分,我们不仅得出了GOHI2022分数的总体概况,还评估了GOHI框架。我们还比较了指标和I-子指标的排名,以更清楚地了解“一个健康”领域内每个地区的优势和劣势。
    GOHI2022的表现显示,国家/地区之间的显着差异在39.03至70.61之间。GOHI2022的全球平均得分为54.82。EDI的平均分,IDI,CDI分别为46.57、58.01和57.25。就全球排名而言,来自北美的国家,欧洲和中亚,东亚和太平洋地区的得分较高。就CDI的一个健康领域而言,抗菌素耐药性得分最低(中位数:43.09),其次是粮食安全(中位数:53.78),治理(中位数:54.77),气候变化(中位数:64.12)和人畜共患疾病(中位数:69.23)。全球范围内,GOHI的分数在空间上有所不同,在北美得分最高,而在撒哈拉以南非洲地区得分最低。此外,有证据表明,国家/地区的社会人口统计学特征与其在某些“一种健康”情景中的GOHI表现之间存在关联。
    GOHI的目标是指导有效的战略,以加强OneHealth的能力建设。凭借先进的技术和每年更新的数据库,加大力度完善GOHI的数据挖掘方法变得势在必行。目标是对实际实施“一个健康”的差距和进展提供深刻的见解,特别是对未来流行病的预测。
    UNASSIGNED: In the 21st century, as globalization accelerates and global public health crises occur, the One Health approach, guided by the holistic thinking of human-animal-environment and emphasizing interdisciplinary collaboration to address global health issues, has been strongly advocated by the international community. An immediate requirement exists for the creation of an assessment tool to foster One Health initiatives on both global and national scales.
    UNASSIGNED: Built upon extensive expert consultations and dialogues, this follow-up study enhances the 2022 global One Health index (GOHI) indicator system. The GOHI framework is enriched by covering three indices, e.g. external drivers index (EDI), intrinsic drivers index (IDI), and core drivers index (CDI). The comprehensive indicator system incorporates 13 key indicators, 50 indicators, and 170 sub I-indicators, utilizing a fuzzy analytic hierarchy process to ascertain the weight for each indicator. Weighted and summed, the EDI, IDI, and CDI scores contribute to the computation of the overall GOHI 2022 score. By comparing the ranking and the overall scores among the seven regions and across 160 countries/territories, we have not only derived an overall profile of the GOHI 2022 scores, but also assessed the GOHI framework. We also compared rankings of indicators and sub I-indicators to provide greater clarity on the strengths and weaknesses of each region within the One Health domains.
    UNASSIGNED: The GOHI 2022 performance reveals significant disparities between countries/territories ranged from 39.03 to 70.61. The global average score of the GOHI 2022 is 54.82. The average score for EDI, IDI, and CDI are 46.57, 58.01, and 57.25, respectively. In terms of global rankings, countries from North America, Europe and Central Asia, East Asia and Pacific present higher scores. In terms of One Health domains of CDI, the lowest scores are observed in antimicrobial resistance (median: 43.09), followed by food security (median: 53.78), governance (median: 54.77), climate change (median: 64.12) and zoonotic diseases (median: 69.23). Globally, the scores of GOHI vary spatially, with the highest score in North America while lowest in sub-Saharan Africa. In addition, evidence shows associations between the socio-demographic profile of countries/territories and their GOHI performance in certain One Health scenarios.
    UNASSIGNED: The objective of GOHI is to guide impactful strategies for enhancing capacity building in One Health. With advanced technology and an annually updated database, intensifying efforts to refine GOHI\'s data-mining methodologies become imperative. The goal is to offer profound insights into disparities and progressions in practical One Health implementation, particularly in anticipation of future pandemics.

    在全球变暖的背景下,加剧地区冲突,去全球化,和疾病的传播,全球粮食安全面临严峻挑战。深入研究中美两国的粮食安全状况,可以为世界各国制定粮食安全政策、推进全球粮食安全治理提供实践经验。在对粮食安全不断演变的内涵进行细致梳理的基础上,本研究采用六个维度——数量安全,质量安全,流通安全,经济安全,生态资源安全,以政策安全为切入点,构建由29个具体指标组成的粮食安全评价指标体系框架。运用CRITIC-MEREC-MARCOS模型对2000-2022年中美两国粮食安全状况进行评价,运用障碍度模型(ODM)模型对中美两国粮食安全的阻碍因素进行识别。结果表明,我国粮食安全水平初步呈现小幅波动,随后是稳步上升的趋势。与美国的差距在不断缩小。然而,中美两国在经济安全方面仍然存在重大差异,生态资源安全,和政策安全。此外,由于农业劳动生产率有限,水资源和土壤资源的短缺,化肥和农药使用效率低,中国的粮食安全受到经济和环境约束。经济安全和生态资源安全对我国粮食安全的制约呈逐年上升趋势。对于美国来说,随着粮食出口的受阻和干旱灾害的日益频繁,流通安全和生态资源安全对粮食安全的影响日益突出。在未来,中美两国应该携手应对挑战,积极推进粮食安全国际合作,推动人类的可持续发展。
    Against the backdrop of global warming, intensifying regional conflicts, deglobalization, and the spread of diseases, global food security is facing severe challenges. Studying the food security situation in China and the United States in depth can provide practical experience for formulating food security policies for countries around the world and promoting global food security governance. On the basis of a meticulous review of the evolving connotations of food security, this study adopts six dimensions-quantity security, quality security, circulation security, economic security, ecological resource security, and policy security-as breakthrough points to construct a framework consisting of food security evaluation indicator system comprising 29 specific indicators. The CRITIC-MEREC-MARCOS model is applied to evaluate the status of food security in China and the United States from 2000 to 2022, while the obstacle degree model (ODM) model is utilized to identify factors impeding food security between the two countries. The results indicate that the level of food security in China has shown slight fluctuations initially, followed by a steady upward trend. The gap with the United States is continuously narrowing. However, significant differences between China and the United States still exist in terms of economic security, ecological resource security, and policy security. Furthermore, due to the limited productivity of agricultural labor, scarcity of water and soil resources, and low efficiency in the use of fertilizers and pesticides, China\'s food security is subject to economic and environmental constraints. The restrictions imposed by economic security and ecological resource security on China\'s food security are showing an increasing trend year by year. For the United States, with the obstruction of grain exports and the increasing frequency of drought disasters, the impact of circulation security and ecological resource security on food security is becoming increasingly prominent. In the future, China and the United States should join hands to address challenges, actively promote international cooperation in food security, and drive sustainable development for humanity.

    农业遗产系统(AHS)的保护在促进农业可持续发展以及维护全球农民的生计和粮食安全方面发挥了关键作用。这种意义在茶叶AHS的情况下尤其明显,由于茶叶产品的经济和营养价值。以安溪铁观音茶树栽培系统(ATTCS)和福建福鼎白茶栽培系统(FWTCS)为例,这项研究使用统计分析和多项逻辑回归模型来评估和比较茶叶AHS站点的农民生计和粮食安全。主要研究结果如下。首先,由于茶产业处于不同的发展阶段,与农业和非农业兼职家庭相比,纯农业家庭的福利水平在ATTCS中最低,而福利是FWTCS中最高的。第二,在ATTCS和FWTCS中,茶园面积和劳动力数量等因素显着影响农民从纯农业家庭到农业兼职家庭的生计策略转变。第三,茶叶产品的高商品率,结合茶园的复合种植,为当地人提供基本的收入来源,食物,和营养,从而提高ATTCS和FWTCS的粮食安全。这些发现对于设计政策以通过AHS和其他可持续农业确保农民的生计和粮食安全至关重要。
    The conservation of agricultural heritage systems (AHSs) has played a pivotal role in fostering the sustainable development of agriculture and safeguarding farmers\' livelihoods and food security worldwide. This significance is particularly evident in the case of tea AHSs, due to the economic and nutritional value of tea products. Taking the Anxi Tieguanyin Tea Culture System (ATTCS) and Fuding White Tea Culture System (FWTCS) in Fujian Province as examples, this study uses statistical analyses and a multinomial logistic regression model to assess and compare farmer livelihood and food security at the tea AHS sites. The main findings are as follows. First, as the tea industries are at different stages of development, compared with agricultural and non-agricultural part-time households, the welfare level of pure agricultural households is lowest in the ATTCS, while welfare is the highest in the FWTCS. Second, factors such as the area of tea gardens and the number of laborers significantly affect farmers\' livelihood strategies transformation from pure agricultural households to agricultural part-time households in the ATTCS and FWTCS. Third, the high commodity rate of tea products, combined with compound cultivation in tea gardens, provides local people with essential sources of income, food, and nutrients, so as to improve food security in the ATTCS and FWTCS. These findings are essential for designing policies to ensure farmers\' livelihoods and food security through AHSs and other sustainable agriculture.
