Food insecurity remains a threat to Nigerians especially agricultural households who are the most vulnerable. This study focuses on the structure of the resilience of agricultural households to food insecurity in Nigeria using the World Bank‘s Living Standard Measurement Studies Integrated Survey on Agriculture (LSMS-ISA), covering four rounds (2010/2011, 2012/2013, 2015/2016 and 2018/2019) using a total of 4975, 4394, 4226 and 4797 households respectively. Data were analysed using Descriptive Statistics, Multiple Indicators Multiple Causes Model and the Random Effects Probit model. The pillars of resilience to food insecurity among agricultural households include access to basic services, asset, agricultural practice and technology, social safety net, adaptive capacity and stability. Results showed that only about 34% of households were resilient to food insecurity during the periods under review. The most essential determinants affecting food insecurity resilience are access to basic services, assets, stability, adaptive capacity and social safety net. Age of household head, livelihood strategy employed, geo-political zones and location of residence significantly influence food insecurity resilience of households. Farmers’ income and food access must be improved as well as their adaptive capacity to food insecurity in order to help them become more resilient to food insecurity and inevitably help in achieving the Sustainable Development goal two of ending hunger in all its forms and improving food security which is one of the main policy thrust of the Nigeria’s economic and sustainability plan and the National Development Plan.
粮食不安全仍然威胁着尼日利亚人,尤其是最脆弱的农户。本研究利用世界银行的农业生活水平测量研究综合调查(lsm - isa),重点研究尼日利亚农户对粮食不安全的抵御能力结构,涵盖四轮(2010/2011年、2012/2013年、2015/2016年和2018/2019年),分别涉及4975、4394、4226和4797户家庭。采用描述性统计、多指标多原因模型和随机效应Probit模型对数据进行分析。农户抵御粮食不安全能力的支柱包括获得基本服务、资产、农业实践和技术、社会安全网、适应能力和稳定性。结果显示,在本报告所述期间,只有约34%的家庭能够抵御粮食不安全。影响粮食不安全复原力的最重要决定因素是获得基本服务、资产、稳定性、适应能力和社会安全网。户主年龄、所采用的生计策略、地缘政治区域和居住地显著影响家庭的粮食不安全抵御能力。必须改善农民的收入和粮食获取以及他们对粮食不安全的适应能力,以帮助他们提高对粮食不安全的抵御能力,并不可避免地有助于实现可持续发展目标二,即消除一切形式的饥饿和改善粮食安全,这是尼日利亚经济和可持续性计划和国家发展计划的主要政策重点之一。

Young farmers have an important role as the future of food security and sustainable agriculture depends on them. However, the young farmer problem is getting serious all over the world, whether the countries are developed or developing. The objective of this study is to determine the factors that affect the willingness of young farmers to continue agriculture in the future, especially based on social and cultural factors with economic factors. Data were collected from 200 young farmers' questionnaires in İzmir, Turkey, and Niigata, Japan. Using the logistic regression model, we found that social factors play an important role in retaining young farmers in agriculture such as the respectability and importance of farming, and the multifunctional role of farming, along with economic factors such as off-farm job, farmland size, and subsidies. If countries can clarify the importance of farming and food production to young generations, they will make essential contributions to the sustainability of food security and agricultural sustainability.
青年农民可以发挥重要作用,因为粮食安全和可持续农业的未来取决于他们。然而,无论发达国家还是发展中国家,青年农民问题在世界各地都变得越来越严重。本研究的目的是确定影响青年农民未来继续从事农业的意愿的因素,特别是基于社会文化因素和经济因素。数据来自土耳其İzmir和日本新泻的200名年轻农民的问卷调查。利用logistic回归模型,我们发现社会因素(如农业的体面性和重要性、农业的多功能作用)以及经济因素(如非农就业、农田规模和补贴)在挽留年轻农民方面发挥了重要作用。如果各国能够明确农业和粮食生产对年轻一代的重要性,它们将对粮食安全和农业可持续性的可持续性作出重要贡献。

The main aim of this study is to analysed the pattern of agglomeration of trade flows in the city of Padang and Teluk Bayur Port with the regencies and cities along the west coast of Sumatra, as well as the factors that influence them. How competitive is trade flow with the West coast region compared to the East coast of Sumatra. The analytical approach used is spatial econometrics, especially the spatial lag model and spatial error model. The data used is the volume of loading and unloading of inter-island and foreign ships at Teluk Bayur Port and other districts and cities in 133 areas on the West Coast and 155 districts and cities in the economic corridors of Sumatra. The results showed that the West Coast trade flow variable had no significant effect on the existence of Padang City as the centre of economic agglomeration in the economic corridor area of Sumatra. Our findings are that trade flows in the city of Padang have not been able to encourage economic agglomeration in regencies and cities on the West Coast of Sumatra, on the contrary there are connections with regencies and cities in the economic corridors of the East Coast of Sumatra. Therefore, to accelerate the process of economic agglomeration through trade flows, joint policies are needed with the agricultural sector in the Sumatran economic corridor in facing global market competition, as well as strengthening inter-regional internal markets in the Sumatra corridor, agricultural commodity transactions between regencies and cities in the Sumatran economic corridor which must be strengthened, so as to be able to compete in a competitive global market.
本研究的主要目的是分析巴东市和直落巴育尔港与苏门答腊岛西海岸的摄政区和城市的贸易流集聚模式,以及影响它们的因素。与苏门答腊岛东海岸相比,西海岸地区的贸易流竞争力如何?本文采用空间计量经济学的分析方法,特别是空间滞后模型和空间误差模型。所使用的数据是在泰鲁克巴尤尔港和西海岸133个地区的其他地区和城市以及苏门答腊经济走廊的155个地区和城市的岛际和外国船只的装卸量。结果表明:西海岸贸易流量变量对巴东市作为苏门答腊经济走廊地区经济集聚中心的存在没有显著影响;我们的研究结果是,巴东市的贸易流动并没有能够鼓励苏门答腊岛西海岸的县域和城市的经济集聚,相反,苏门答腊岛东海岸的经济走廊与县域和城市有联系。因此,要通过贸易流动加速经济集聚的进程,需要与苏门答腊经济走廊内的农业部门共同制定政策,面对全球市场竞争,加强苏门答腊经济走廊区域间的内部市场,加强苏门答腊经济走廊内县域与城市之间的农产品交易,从而能够在竞争激烈的全球市场中竞争。

This study examines the impact of agricultural Gross Domestic Product (GDP) and imports on Nigeria’s food commodity prices using annual data from 1981 to 2018. Data obtained were analysed using the unit root test, cointegration test and Autoregressive Distributed Lag (ARDL) model to evaluate the long-run and short-run effects of the hypothesized variables on the food commodity prices. The results reveal that maize import value and exchange rate significantly affect the price of maize in the short-run. In contrast, the lagged price of maize, maize output and the past value of maize imports are the factors that influenced the current price of maize within the review period. Also, the lagged price of rice, rice output and the lagged value of rice imported in the immediate year exerted significant influences on the price of rice in Nigeria. Furthermore, the study indicates that the lagged price of wheat, the import value of wheat and the lagged wheat import value were statistically significant in influencing wheat price in Nigeria. Hence, policies for flexibility in the harmonization of exchange rate movements strengthen domestic agricultural performance.
本研究利用1981年至2018年的年度数据,考察了农业国内生产总值(GDP)和进口对尼日利亚粮食商品价格的影响。采用单位根检验、协整检验和自回归分布滞后(ARDL)模型对所得数据进行分析,评估假设变量对食品价格的长期和短期影响。结果表明,玉米进口价值和汇率在短期内显著影响玉米价格。相比之下,滞后的玉米价格、玉米产量和过去的玉米进口价值是影响本报告所述期间玉米当前价格的因素。此外,大米的滞后价格、大米产量和当年进口大米的滞后价值对尼日利亚的大米价格产生了重大影响。此外,研究表明,小麦滞后价格、小麦进口价值和小麦进口滞后价值对尼日利亚小麦价格的影响具有统计学意义。因此,灵活协调汇率变动的政策可加强国内农业绩效。

The article aims to analyze the potential of organic production in Ukraine in war conditions and determine its consequences for world food security. Methodological approaches based on cluster and rating analysis of regions based on their potential in the field of organic production are proposed and provide an appropriate evaluation algorithm, mathematical tools, and strategic alternatives for all variants of data obtained in the calculation process. With the help of the given methodological approaches, the development of strategies for organic production for the primary clustering of regions, namely in Kyiv, Odesa, and Cherkasy oblasts, is proved. The system of forming a regional model of organically oriented multidisciplinary agriculture is appropriate for these regions. This will create the preconditions for organic food production, organic livestock, and related sectors of environmentally oriented economic activities. The development of an innovative component for implementing SMART-specialization projects is possible. It is substantiated that the most affected regions (Kharkiv, Luhansk, Donetsk, Kherson, Mykolaiv, Zaporizhia) from hostilities and occupation are potential for organic production and have significant areas for agricultural production. It is projected that the other war in Ukraine will reduce the production of farm products, including organic, which will lead to food security in most countries.
本文旨在分析乌克兰在战争条件下有机生产的潜力,并确定其对世界粮食安全的影响。提出了基于区域有机生产潜力的聚类和评级分析方法,并为计算过程中获得的所有数据变体提供了适当的评估算法、数学工具和战略选择。在给定的方法方法的帮助下,证明了在基辅,敖德萨和切尔卡西州的主要区域集群的有机生产战略的发展。形成以有机农业为导向的多学科农业区域模式体系是适合这些地区的。这将为有机食品生产、有机牲畜和相关部门的环境导向型经济活动创造先决条件。为实施智能专业化项目开发创新组件是可能的。事实证明,受敌对行动和占领影响最严重的地区(哈尔科夫、卢甘斯克、顿涅茨克、赫尔松、尼古拉耶夫、扎波罗热)具有有机生产的潜力,有大量的农业生产面积。据预测,乌克兰的另一场战争将减少农产品的生产,包括有机农产品,这将导致大多数国家的粮食安全。

Through some empirical studies, the flow of FDI and trade openness have proven to support economic growth in developing countries. This paper examines the significance of FDI and trade openness in five African countries (Ghana, Morocco, Kenya, Uganda, and Zambia). The study employed the panel data analysis method using data from the World Bank for the period 1994-2019 for the five selected countries. The result from the Random effect model indicated that FDI positively supports growth, whereas trade openness harms economic growth in these countries. The outcome further revealed that Uganda enjoys more significance than the other countries using the countries' dummies through the pooled model estimation. We recommend that various governments focus more on exports, reduce imports, attract more FDI through incentives, and create a regulatory environment that is friendly to FDI.
通过一些实证研究,FDI的流动和贸易开放已被证明能够支持发展中国家的经济增长。本文考察了五个非洲国家(加纳、摩洛哥、肯尼亚、乌干达和赞比亚)的外国直接投资和贸易开放的重要性。该研究采用了面板数据分析方法,使用了世界银行1994-2019年期间对五个选定国家的数据。随机效应模型的结果表明,FDI对这些国家的经济增长有积极的支持作用,而贸易开放对这些国家的经济增长有不利的影响。结果进一步表明,乌干达比其他国家享有更大的意义,使用这些国家的假人通过汇集模型估计。我们建议各国政府更多地关注出口,减少进口,通过激励措施吸引更多外国直接投资,并创造对外国直接投资友好的监管环境。

This study proposes an Encapsulated Conceptual Framework (ECF) for understanding the links between Information and Communication Technologies (ICTs), water resource management activities, and Sustainable Development Goals (SDGs). The study aims to contribute to national, regional, and global debates on the potential of ICTs in achieving sustainability goals. A combination of two socio-technical theories - Relevance Theory (RT) and Technology Acceptance Model (TAM) was adopted to inform the study. The literature review further informed the construction of the ECF. The framework testing involved sampling participants and collecting and analyzing the data. A sample of 251 (n = 251) individuals from formal and informal water user groups on the Tanzanian side of the Lake Victoria Basin participated in testing the framework. The study adopted the cross-sectional design to a mixed research approach. Furthermore, it used three quantitative and qualitative data collection techniques: Focus Group Discussions (FGDs), Key Informant Interviews (KIIs), and Questionnaire Administration (QA). Each FGDs session accommodated a group of participants with 9 – 12 members across the selected sites. KIIs targeted groups network leaders, water resource managers at various levels, and other individuals with potential information. Gathered dataset was cleaned, summarized, and analyzed using descriptive, correlation, and content analytical methods. The study capitalized on the strength of Tableau and R statistics to produce the visualizations that support the descriptive analysis of the data. Furthermore, the study used R and MS Excel software to establish the relationships among the variables. Results indicated the prominent use of mobile as ICTs for freshwater management activities. Furthermore, mobile-based tools such as SMS, voice call, image and video supported these activities to attain some indicators of SDGs related to water resource management. The study concludes that the framework contributes to understanding the contextual issues on ICT, freshwater management and SDGs.
本研究提出了一个封装概念框架(ECF),用于理解信息和通信技术(ICT)、水资源管理活动和可持续发展目标(SDG)之间的联系。该研究旨在促进国家、区域和全球关于信通技术在实现可持续发展目标方面潜力的辩论。采用关联理论(RT)和技术接受模型(TAM)两种社会技术理论相结合的方法进行研究。文献综述进一步为ECF的构建提供了信息。框架测试包括对参与者进行抽样,并收集和分析数据。来自维多利亚湖流域坦桑尼亚一侧正式和非正式用水群体的251人(n=251)参与了该框架的测试。该研究采用了横断面设计的混合研究方法。此外,它使用了三种定量和定性的数据收集技术:焦点小组讨论(FGD)、关键知情者访谈(KII)和问卷管理(QA)。每个FGD会议都有一组参与者,他们在选定的地点有9-12名成员。KII针对的是网络领导者、各级水资源管理人员和其他掌握潜在信息的个人。使用描述性、相关性和内容分析方法对收集的数据集进行清理、总结和分析。该研究利用Tableau和R统计数据的优势,产生了支持数据描述性分析的可视化结果。此外,本研究使用R和MS Excel软件来建立变量之间的关系。结果表明,移动通信技术在淡水管理活动中得到了突出应用。此外,短信、语音通话、图像和视频等基于移动的工具支持这些活动,以实现与水资源管理相关的可持续发展目标的一些指标。该研究得出结论,该框架有助于理解信息和通信技术、淡水管理和可持续发展目标的背景问题。

Each FGDs session accommodated a group of participants with 9 – 12 members across the selected sites. KIIs targeted groups network leaders, water resource managers at various levels, and other individuals with potential information. Gathered dataset was cleaned, summarized, and analyzed using descriptive, correlation, and content analytical methods. The study capitalized on the strength of Tableau and R statistics to produce the visualizations that support the descriptive analysis of the data. Furthermore, the study used R and MS Excel software to establish the relationships among the variables. Results indicated the prominent use of mobile as ICTs for freshwater management activities. Furthermore, mobile-based tools such as SMS, voice call, image and video supported these activities to attain some indicators of SDGs related to water resource management. The study concludes that the framework contributes to understanding the contextual issues on ICT, freshwater management and SDGs.","PeriodicalId":38587,"journal":{"name":"Agris On-line Papers in Economics and Informatics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43239541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change is having a major impact on various sectors such as agriculture and water management due to changes in the distribution of rainfall. Mitigation of climate change impacts can be achieved through early detection of these changes by monitoring systems and the adoption of appropriate adaptation measures. One of the main goals is to design and develop a next generation monitoring and alerting system to support the optimization of water and soil nutrient management in agricultural domain. Sensors and sensor data management play an important in this kind of monitoring systems. A complete sensor data chain was developed based on modern wireless sensor networks and IoT technologies that covers the data gathering up to the data publication by interoperable interfaces. The monitoring system was tested on vineyards in pilot localities in Czech Republic and in Argentina.

Pálinka is the national spirit of Hungary and is in possession of the geographical indication of the European Union, but it used to be listed as a poor-quality product for a long time. The turnaround in this field began in the early 2000s. The aim of this study is to analyse the behaviour and attitudes regarding the purchase and consumption of pálinka and, to assess the product-related awareness of Hungarian consumers who like this particular spirit. Based on the literature, the knowledge of Hungarian consumers about pálinka is rather low, which is confirmed by the results of our questionnaire survey of 1,000 people. Furthermore, based on the results obtained, participants in the pálinka sector are more likely to understand how important certain product attributes that are perceived by consumers when purchasing pálinka. In order to increase the awareness of the spirit, it is essential to get to know the consumers, which can be followed by a well-positioned marketing strategy from both the government and corporate side.
帕林卡是匈牙利的民族精神,拥有欧盟的地理标志,但它曾长期被列为劣质产品。这一领域的转变始于21世纪初。本研究的目的是分析购买和消费帕林卡的行为和态度,并评估喜欢这种特殊精神的匈牙利消费者的产品相关意识。根据文献,匈牙利消费者对pálinka的了解程度相当低,我们对1000人的问卷调查结果证实了这一点。此外,根据获得的结果,帕林卡行业的参与者更有可能了解消费者在购买帕林卡时所感知的某些产品属性有多重要。为了提高人们对这种精神的认识,了解消费者是至关重要的,政府和企业都可以采取定位良好的营销策略。

Agricultural activities produce the significant amounts of greenhouse gas emission. The importance of an ever-changing climate means that digital technologies and their environmental impact are more frequently discussed in the context of the 5th Industrial Revolution. It is important to minimize environmental threats and reduce production waste on the way to a sustainable path. The main scientific aim of the paper is to examine, based on correlation analysis and ANOVA method, the relationship between two variables, digital performance of individual EU countries expressed by the indicator Digital Economy and Society Index and production of Greenhouse Gas Emissions, specifically how digital technologies affect the environment and how to transform digital technologies to supporting the European Green Deal and accelerate sustainable growth. The reasons are that digital technologies can play an important role in reducing greenhouse gas emissions. According to the results, it has been proven that exists a positive correlation between two variables regarding as a weak correlation between DESI and GHG emissions. Analysis of variance indicates the highly significant differences between variables. Countries with the higher DESI index produce more Greenhouse gas emissions as well but in a weak manner.
农业活动产生了大量的温室气体排放。不断变化的气候的重要性意味着数字技术及其对环境的影响在第五次工业革命的背景下被更频繁地讨论。在通往可持续发展道路的道路上,最大限度地减少环境威胁和减少生产浪费是很重要的。本文的主要科学目的是基于相关性分析和方差分析方法,检验两个变量之间的关系,即用数字经济和社会指数表示的个别欧盟国家的数字表现与温室气体排放量的生产,特别是数字技术如何影响环境,以及如何将数字技术转化为支持欧洲绿色协议和加速可持续增长。原因是数字技术可以在减少温室气体排放方面发挥重要作用。根据研究结果,已经证明两个变量之间存在正相关性,即DESI和GHG排放之间的弱相关性。方差分析表明变量之间存在高度显著差异。DESI指数较高的国家也产生了更多的温室气体排放,但排放量较弱。
