    食用昆虫被认为是一个令人难以置信的机会,可以缓解未来十年面对气候变化不确定性,为不断增长的世界人口可持续生产健康食品的重大挑战。在这项研究中,我们评估了Achetadomesticus的营养成分和感官特性,Apismellifera,Gnathoceratrivittata,非洲Gryllotalpa,伊布拉西亚,Imbrasiaoyemensis,蝗虫迁徙,亚类,Nomadacrisseptemfasciata,Rhyncophorusphoenicis,Ruspolia不同,Rhynchophorusferrugineus在刚果民主共和国东部消费。被调查的食用昆虫高度赞赏和营养丰富,蛋白质(20.67-43.93克/100克)和脂肪(14.53-36.02克/100克)是主要的宏观营养素,证明他们通过丰富食物改善饮食的潜力。高钾(24-386.67毫克/100克),钠(152-257.82毫克/100克),镁(32-64毫克/100克),铁(5.3-16.13毫克/100克),钙(25-156.67mg/100g)和锌(11-19.67mg/100g)的含量使评估的食用昆虫成为有用的含矿物质成分,可用于预防受微量营养素缺乏困扰的国家的营养不良。矩阵的散点图和Pearson的感官属性和营养成分之间的相关性显示蛋白质和外观之间的负相关(r=-0.45)。虽然在营养属性和感官接受度之间没有观察到很强的相关性,钾和香气之间呈正相关(r=0.50),回味(r=0.50)和可接受性(r=0.52)。主成分分析结果表明,在刚果民主共和国东部,这两个轴占观察到的常见食用昆虫的营养成分和感官属性变异性的97.4%。鉴于本文强调的食用昆虫的显着美味和营养潜力,家庭可以依靠后者来满足他们的营养需求,而不是传统的牲畜,从而通过本地商业机会促进环境和金融安全。
    Edible insects are perceived as an incredible opportunity to mitigate the major challenge of sustainably producing healthy foods for a growing world population in the face of climate change uncertainties over the coming decade. In this study, we assessed the nutrient composition and sensory properties of Acheta domesticus, Apis mellifera, Gnathocera trivittata, Gryllotalpa africana, Imbrasia epimethea, Imbrasia oyemensis, Locusta migratoria, Macrotermes subhylanus, Nomadacris septemfasciata, Rhyncophorus phoenicis, Ruspolia differens and Rhynchophorus ferrugineus consumed in Eastern D. R. Congo. The investigated edible insects are highly appreciated and nutritious, with proteins (20.67-43.93 g/100 g) and fats (14.53-36.02 g/100 g) being the major macro-nutrients, proving their potential to improve diets through food enrichment. The high potassium (24-386.67 mg/100 g), sodium (152-257.82 mg/100 g), magnesium (32-64 mg/100 g), iron (5.3-16.13 mg/100 g), calcium (25-156.67 mg/100 g) and zinc (11-19.67 mg/100 g) content make the assessed edible insects a useful mineral-containing ingredient for preventing undernutrition in countries which are plagued by micronutrient deficiencies. A scatter plot of matrices and Pearson\'s correlations between sensory attributes and nutritional composition showed a negative correlation (r = - 0.45) between protein and appearance. While no strong correlation was observed between nutritional attributes and sensory acceptance, a positive correlation was observed between potassium and aroma (r = 0.50), after-taste (r = 0.50) and acceptability (r = 0.52). Principal component analysis results indicated that the two axes accounted for up to 97.4% of the observed variability in the nutrient composition and sensory attributes of commonly consumed edible insects in the Eastern D. R. Congo. Given the significant delicacy and nutritional potential of edible insects highlighted in this paper, households can rely on the latter to meet their nutritional needs rather than conventional livestock, thus contributing to environmental and financial security through local business opportunities.

    由于农业生产与环境发展的矛盾,粮食安全和碳减排问题不能孤立,实现耦合协调发展是农业可持续发展的关键。本研究采用耦合协调模型和动态定性比较分析(动态QCA)方法,测算了2010-2021年我国31个省份粮食安全指数(FSI)和农业碳排放效率(ACEE)的耦合协调度(CCD),寻求气候智慧型农业技术实现高度耦合协调的路径。外部环境,和激励维度,并模拟各种CSA优先级场景下的路径选择差异。结果表明,中国FSI和ACEE的CCD逐年增加,区域差异显著,主要体现在东北>东部>西部>中部地区。根据CSA的方向,提出了“技术-环境保障”联动路径和“技术-环境-激励”混合路径。不同地区的CSA实践存在差异,这需要基于其独特的社会经济定制,生态,和政治景观。当优先事项有利于粮食安全时,“技术-环境-激励”混合途径支持高CCD,随着优先事项的增加,CSA技术的贡献,以节水灌溉为中心,增加,外部环境的作用减弱。当优先趋势是减少排放时,两种路径都可以实现高CCD。随着碳排放的优先趋势增加,城市化和CSA技术,如节水灌溉和秸秆还田,成为促进更高耦合协调的重要因素,农业相关财政支出的作用减弱。这些发现为保障粮食安全和低碳农业提供了政策支持。
    Owing to the contradiction between agricultural production and environmental development, the issues of food security and carbon mitigation cannot be isolated, and achieving coupled and coordinated development is the key to agricultural sustainability. This study adopted the coupled coordination model and dynamic qualitative comparative analysis (dynamic QCA) method to measure the coupled coordination degree (CCD) of the food security index (FSI) and agricultural carbon emission efficiency (ACEE) in 31 provinces of China from 2010 to 2021, seeking paths to achieve high coupled coordination from Climate-Smart Agriculture technology, external environment, and incentive dimensions, and simulating path selection differences under various CSA priority scenarios. The results indicated that the CCD of the FSI and ACEE in China significantly increased year-on-year increase, with significant regional differences primarily reflected in the Northeast > East > West > Central regions. Based on the CSA orientation, the \"technology-environmental safeguard\" linkage path and the \"technology-environment-incentive\" hybrid path are proposed. There are differences in CSA practices across regions, which require customization based on their unique socioeconomic, ecological, and political landscapes. When priorities favour food security, the \"technology-environment-incentive\" hybrid pathway supports high CCD, and as priorities increase, the contribution of CSA technologies, centred on water-saving irrigation, increases and the role of the external environment diminishes. When the priority tendency is to mitigate emissions, both paths can achieve high CCD. As the priority tendency for carbon emissions increases, urbanisation and CSA technologies such as water-saving irrigation and straw return become essential factors contributing to higher coupling coordination, and the role of agriculture-related financial expenditures diminishes. These findings provide policy support for safeguarding food security and low-carbon agriculture.

    俄罗斯-乌克兰冲突在全球范围内日益受到关注,对地区和全球粮食安全构成严重威胁。使用玉米的月度贸易数据,大米,2016/1至2023/12年,本文构建了三个国际作物贸易网络和一个国际粮食贸易网络。我们旨在研究俄罗斯-乌克兰冲突发生后的结构变化。我们发现边的数量发生了显著的变化,平均程度,密度,和2022年第三季度的效率,特别是在国际小麦贸易网。此外,我们已经表明,政治原因导致北大西洋公约组织经济与俄罗斯之间的贸易联系发生了比与乌克兰更明显的变化。本文可以提供有关地缘政治冲突对全球粮食系统的负面影响的见解,并鼓励采取一系列有效策略来减轻冲突对全球粮食贸易的负面影响。
    The Russia-Ukraine conflict is a growing concern worldwide and poses serious threats to regional and global food security. Using monthly trade data for maize, rice, and wheat from 2016/1 to 2023/12, this paper constructs three international crop trade networks and an aggregate international food trade network. We aim to examine the structural changes following the occurrence of the Russia-Ukraine conflict. We find significant shifts in the number of edges, average in-degree, density, and efficiency in the third quarter of 2022, particularly in the international wheat trade network. Additionally, we have shown that political reasons have caused more pronounced changes in the trade connections between the economies of the North Atlantic Treaty Organization and Russia than with Ukraine. This paper could provide insights into the negative impact of geopolitical conflicts on the global food system and encourage a series of effective strategies to mitigate the negative impact of the conflict on global food trade.

    关键要素,或柱子,粮食安全被称为粮食供应,食物获取,食物利用,和稳定性。这些粮食安全支柱通常与国家的粮食安全干预措施有关,社区或家庭层面。然而,如果城市“家庭”是任何食品安全干预的利益单位,这项研究询问是否有更全面的元素,或者柱子,是需要的。这项研究的目的是探索粮食安全/不安全的社会经济方面,我们称之为“食物可得性”研究的结果。通过使用结构化问卷(n=120),并分析了来自Awka市当地市场和超市环境的数据,尼日利亚,食物可获得性的概念已经出现,并被概念化和批判。本文的贡献是构建尼日利亚粮食安全可获得性的概念,以便更好地了解影响家庭城市粮食安全/不安全的因素以及如何有效缓解这些因素。出现的可获取性因素是文化,时间贫困,资源可用性和烹饪技能,以及家庭食物偏好和膳食选择。
    The key elements, or pillars, of food security are stated as food availability, food access, food utilization, and stability. These food security pillars are often linked to food security interventions at the national, community or household level. However, if the urban \'household\' is the unit of interest for any food security intervention, this research asks if a more holistic element, or pillar, is needed. The aim of this research has been to explore the socio-economic aspects of food security/insecurity that we have termed as a result of the research \"food acquirability\". Through the use of structured questionnaires (n = 120), and analysis of the data derived from local market and supermarket settings in the city of Awka, Nigeria, the concept of food acquirability has emerged and been conceptualized and critiqued. The contribution of this paper is to frame the concept of acquirability with regard to food security in Nigeria in order to develop a better understanding of the factors that impact household urban food security/insecurity and how they can be effectively mitigated. Factors of acquirability that emerged were culture, time poverty, resource availability and cooking skills, and household food preference and meal choice.

    作为社会化服务的主要服务模式和管理模式,农业生产托管服务(APTS)是实现农民与现代农业发展紧密联系的重要途径,这对于确保国家粮食安全非常重要。通过构建农民实用模型,本文从自然风险和非农就业收入(NAEI)双重机制出发,推导了农户APTS的决策机制,并利用东北三省956个农户的调查数据,运用多元logit(Mlogit)和倾向得分匹配(PSM)方法对实证结果进行了验证。研究表明,自然风险阻碍了农民对APTS的选择;NAEI对APST有积极影响,NAEI的增加削弱了自然风险对APTS选择的负面影响,并具有增强的调节作用。此外,尺度异质性分析表明,自然风险和NAEI对不同尺度农户的影响存在显著差异。NAEI调节效应对小农影响最大,其次是中等规模的农民。鉴于此,政府应稳定非农就业市场,改善农民非农就业机会。APTS组织应转移自然风险,完善农业保险制度。根据不同农户规模的差异,制定不同的推广政策,并提出扩大管理和深化服务,进一步推动APTS的发展,夯实我国粮食安全基础。
    As the main service mode and management mode of socialized service, agricultural production trusteeship services (APTS) are an important way to realize the tight link between farmers and modern agricultural development, which is highly important for ensuring national food security. By constructing a utility model of farmers, this paper deduces the decision-making mechanism of farmers\' APTS from the dual mechanism of natural risk and non-agricultural employment income (NAEI) and uses the survey data of 956 farmers in the three northeastern provinces to verify the empirical results by using multivariate logit (Mlogit) and propensity score matching (PSM) methods. The research shows that natural risk hinders farmers\' choice of the APTS; NAEI has a positive impact on APST, and an increase in NAEI weakens the negative effect of natural risk on the choice of the APTS, and has an enhanced moderating effect. In addition, the scale heterogeneity analysis revealed that the impacts of natural risk and NAEI on farmers of different scales are significantly different. The NAEI adjustment effect has the greatest impact on small-scale farmers, followed by medium-scale farmers. In view of this, the government should stabilize the nonagricultural employment market and improve the nonagricultural employment opportunities of farmers. APTS organizations should transfer natural risks and improve the agricultural insurance system. According to the differences of different scales of farmers, different promotion policies are formulated, and the expansion of management and deepening services is proposed to further promote the development of APTS and consolidate the foundation of food security in China.

    农业,人类文明的基石,面临气候变化带来的日益严峻的挑战,资源限制,和停滞不前的收益率。精确的作物产量预测对于制定贸易政策至关重要,发展战略,人道主义倡议。本研究引入了一个全面的机器学习框架,旨在预测作物产量。我们在适度碳排放情景下利用CMIP5气候预测来评估农业用地的未来适宜性,并纳入气候数据,历史农业趋势,和化肥用量对项目产量的影响。我们的综合方法预测到2028年东南亚作物产量的显着区域变化,确定潜在的耕地利用。具体来说,印度尼西亚的农田面积,马来西亚,菲律宾,如果不采取行动,越南预计将下降10%以上,并且有可能减轻这种损失。此外,越南的大米产量预计将下降19%,泰国将下降7%,而菲律宾可能会看到与2021年相比5%的增长。我们的发现强调了气候变化和人类活动对农业生产力的关键影响,为决策和促进国际合作提供必要的见解。
    Agriculture, a cornerstone of human civilization, faces rising challenges from climate change, resource limitations, and stagnating yields. Precise crop production forecasts are crucial for shaping trade policies, development strategies, and humanitarian initiatives. This study introduces a comprehensive machine learning framework designed to predict crop production. We leverage CMIP5 climate projections under a moderate carbon emission scenario to evaluate the future suitability of agricultural lands and incorporate climatic data, historical agricultural trends, and fertilizer usage to project yield changes. Our integrated approach forecasts significant regional variations in crop production across Southeast Asia by 2028, identifying potential cropland utilization. Specifically, the cropland area in Indonesia, Malaysia, Philippines, and Viet Nam is projected to decline by more than 10% if no action is taken, and there is potential to mitigate that loss. Moreover, rice production is projected to decline by 19% in Viet Nam and 7% in Thailand, while the Philippines may see a 5% increase compared to 2021 levels. Our findings underscore the critical impacts of climate change and human activities on agricultural productivity, offering essential insights for policy-making and fostering international cooperation.

    减少稻谷中的镉(Cd)污染对于确保粮食安全和促进可持续农业至关重要。由于其成本效益和操作简单,利用遗传修饰产生低Cd积累的水稻品种是一种有前途的策略。我们的研究表明,CRISPR-Cas9介导的多铜氧化酶基因OsLPR1/3/4/5在粳稻品种通经981中的四重突变对产量影响不大。然而,与Cd结合的细胞壁官能团显着增加。因此,OsLPR1/3/4/5的四重突变增强了细胞壁内的Cd固存,同时降低了木质部和韧皮部汁液中的Cd浓度,从而抑制Cd从根到芽的运输。因此,oslpr1/3/4/5四重突变体中糙米和稻壳中的Cd浓度(qm)分别下降了52%和55%,分别,与野生型相比。这些发现表明,OsLPR1/3/4/5的四重突变是在不影响产量的情况下最大程度地减少水稻籽粒中Cd污染的有效方法。因此,通过生物技术途径对OsLPR1/3/4/5进行的四重突变可能是产生低Cd积累的水稻新品种的有价值的策略。
    Minimizing cadmium (Cd) contamination in rice grains is crucial for ensuring food security and promoting sustainable agriculture. Utilizing genetic modification to generate rice varieties with low Cd accumulation is a promising strategy due to its cost-effectiveness and operational simplicity. Our study demonstrated that the CRISPR-Cas9-mediated quadruple mutation of the multicopper oxidase genes OsLPR1/3/4/5 in the japonica rice cultivar Tongjing 981 had little effect on yields. However, a notable increase was observed in the cell wall functional groups that bind with Cd. As a result, the quadruple mutation of OsLPR1/3/4/5 enhanced Cd sequestration within the cell wall while reducing Cd concentrations in both xylem and phloem sap, thereby inhibiting Cd transport from roots to shoots. Consequently, Cd concentrations in brown rice and husk in oslpr1/3/4/5 quadruple mutants (qm) decreased by 52% and 55%, respectively, compared to the wild-type. These findings illustrate that the quadruple mutation of OsLPR1/3/4/5 is an effective method for minimizing Cd contamination in rice grains without compromising yields. Therefore, the quadruple mutation of OsLPR1/3/4/5 via biotechnological pathways may represent a valuable strategy for the generation of new rice varieties with low Cd accumulation.

    Water, energy, and food insecurity are significant challenges that affect both economies and households, particularly in developing countries. These resources have an effect on households wellbeing, businesses, and all sectors of the economy, making them critical to ensuring household well-being, which is frequently measured by quintile welfare. As a result, there has been a significant increase in interest in securitizing these resources in order to mitigate their negative effects on household\'s wellbeing This study provides an empirical investigation of the determinants of water, energy, and food (WEF) security and the effect of water, energy, and food security on household well-being in Ghana. This study provides an empirical investigation of the determinants of water, energy, and food (WEF) security and the effect of water, energy, and food security on household well-being in Ghana. The study used a sample of 2,735 households from the Ghana Living Standard Survey (GLSS) Wave 7. We applied an instrumental variable probit, complementary log-log and ordered Probit estimation techniques for analysis. Empirical analysis reveals several important findings. Firstly, factors such as age, credit access, household location, employment status, and livestock ownership positively contribute to household water security, while remittances, water supply management, water bills, and water quantity have negative impacts. Secondly, age, marital status, household size, remittances, and livestock ownership significantly influence household energy security. Thirdly, marital status, household income, credit access, and household size are crucial determinants of household food security, with residence and region of household location exerting negative effects. Additionally, while water and energy security have a relatively lower impact on household well-being, food security emerges as a key driver in promoting household wellbeing. The study recommends that policymakers and stakeholders design and implement robust programs and interventions to sustain households\' water, energy, and food supply.
