Attention is focused on the historical transformation of regional food systems. The latter are interpreted as diversified, regionally defined systems of production, transportation, consumption, as well as aesthetic and spiritual perception of food products based on the use of resources, both of local origin and those attracted from outside. The general approaches to understanding the evolution of regional food systems are considered without specifying the past and present pictures of the differentiated food space. An attempt is made to find the connection of spatial food systems with the "pyramid of needs" by A. Maslow. A special role in the spatial transformation of the food sector is assigned to the process of globalization and, in particular, the strengthening of the hegemony of agrarian transnational corporations, strengthening their influence on the dynamics and structure of production, as well as on food consumption. The connection of the global expansion of food trade networks with the evolution of national cuisines, which are a specific subsystem of the world's food systems, as well as with the so-called "cultural sovereignty" of countries, is noted. It is concluded that it is important to study the sustainable dependencies of regional food systems, manifested in various socio-economic conditions.
注意力集中在区域粮食系统的历史转型上。后者被解释为多样化的、区域界定的生产、运输、消费系统,以及基于对本地和外来资源的利用而对食品的审美和精神感知。理解区域食物系统演变的一般方法被认为没有指定过去和现在的不同食物空间的图片。试图找出空间食物系统与马斯洛的“需求金字塔”之间的联系。全球化进程,特别是加强农业跨国公司的霸权,加强它们对生产的动力和结构以及对粮食消费的影响,在粮食部门的空间转变中发挥了特殊作用。报告指出,粮食贸易网络的全球扩张与作为世界粮食系统一个具体子系统的国家菜系的演变以及与国家所谓的“文化主权”之间的联系。结论是,重要的是要研究在各种社会经济条件下表现出来的区域粮食系统的可持续依赖关系。

Rainfall-related impacts on a terraced landscape: Sóller valley (Mallorca, Spain) December 2016-January 2017 降雨对梯田景观的影响:Sóller山谷(西班牙马略卡岛)2016年12月至2017年1月

High Precipitation Events (HPEs) are common in the Mediterranean basin, causing effects such as floods or landslides. Those effects cause impacts, ranging from economic damages to the loss of life. Amongst the damages, the impact on man-made landscapes is also common, affecting both rural and urbanized spaces. The terraced land, built across the Mediterranean, for farming purposes, suffers from HPEs when the terraces cannot cope with the large amount of falling rain. In that sense, it is important to study how rainfall affects the terraces in terms of rock fall and mass movements. Such impacts can damage the economic purpose of the farmlands but also affect other activities developed on rural spaces, like trekking or biking. In this research, the impact of precipitation over a heavily terraced valley in Mallorca is studied, both in terms of impacts and regarding human-related leisure activities as well. The methodology follows five steps, combining aerial photos and satellite images analysis with fieldwork and the study of the obtained data using computer tools. The results show how the terraces cannot cope with large amounts of rain, which increase the risk of collapse and affecting activities developed in these areas. The need of measures to protect those cultural landscapes is highlighted as well as the need of an improved statistical analysis, because results show a moderate correlation between rainfall and stones movement across terraces.
高降水事件(HPE)在地中海盆地很常见,会造成洪水或山体滑坡等影响。这些影响造成了从经济损失到生命损失的各种影响。在破坏中,对人造景观的影响也很常见,既影响农村空间,也影响城市空间。这片横跨地中海的梯田是为了耕种而建的,当梯田无法应对大量降雨时,就会受到HPE的影响。从这个意义上说,研究降雨如何从落石和岩体运动的角度影响阶地是很重要的。这种影响可能会损害农田的经济用途,但也会影响在农村空间开发的其他活动,如徒步旅行或骑自行车。在这项研究中,研究了降水对马略卡岛一个梯田密集的山谷的影响,包括对人类休闲活动的影响。该方法遵循五个步骤,将航空照片和卫星图像分析与实地调查和使用计算机工具对所获得的数据进行研究相结合。研究结果表明,梯田无法应对大量降雨,这增加了坍塌的风险,并影响了这些地区的活动。强调了保护这些文化景观的措施的必要性以及改进统计分析的必要性,因为研究结果显示,降雨和石头在梯田上的移动之间存在适度的相关性。

Poor land-use practices have threatened the livelihood of rural people in Ethiopia. This study assessed the local perception of the impact of land degradation on rural livelihood in the Blue Nile river headwaters, North Gojjam sub-basin. To achieve this objective, questionnaires were administered for 414 sample households and series of focus group discussions and detailed interviews were held with participants. Descriptive statistics were used to analyze quantitative data while qualitative data were buildup using narration and simple description approaches. The finding showed that all local farmers perceived that land degradation was the main local ecological problem since 2008 in the form of soil erosion, soil nutrient depletion; soil acidity and soil biodiversity loss. Most of them (62.54%) perceived as land degradation severity was high and increasing through time, primarily on cereal crop land. Population growth, using animal dung and crop residue for domestic cooking and heating energy, free grazing, using crop residue for construction, absence of fallowing, poor farming, steep slope, and using inappropriate SWC technologies are the main causes of land degradation in the study area. Most local farmers observed as land degradation has decreased crop and livestock productivity, firewood, and surface water resources accessibility. These resulted in the decline in households’ food security and net income over the last 10 years. The finding showed that farmers used traditional ditche, hillside terrace, soil bund, stone bund, check dam, and waterway to reduce land degradation. To reduce the effect of abject land degradation and to improve rural livelihood in the north Gojjam sub-basin, adopting landscape friendly sustainable land management technologies, encouraging various off-farm livelihoods strategies, upgrading livestock feeding systems, and inspiring sustainable energy sources are very urgent.
不良的土地使用做法威胁到埃塞俄比亚农村人民的生计。本研究评估了当地对北戈贾姆次流域青尼罗河源头土地退化对农村生计影响的看法。为了实现这一目标,对414个样本家庭进行了问卷调查,并对参与者进行了一系列焦点小组讨论和详细访谈。描述性统计学用于分析定量数据,而定性数据则使用叙述和简单描述方法进行构建。调查结果表明,自2008年以来,所有当地农民都认为土地退化是当地的主要生态问题,表现为土壤侵蚀、土壤养分流失;土壤酸度和土壤生物多样性丧失。其中大多数(62.54%)被认为土地退化的严重程度很高,并随着时间的推移而增加,主要发生在谷类作物土地上。人口增长、将动物粪便和作物残渣用于家庭烹饪和取暖、自由放牧、将作物残渣用于建筑、没有休耕、农业条件差、坡度陡峭以及使用不适当的SWC技术是研究区域土地退化的主要原因。大多数当地农民认为,土地退化降低了作物和牲畜的生产力、木柴和地表水资源的可及性。这导致家庭的粮食安全和净收入在过去10年中有所下降。研究结果表明,农民使用传统的沟渠、山坡阶地、土堤、石堤、淤地坝和水道来减少土地退化。为了减少土地严重退化的影响,改善北Gojjam次流域的农村生计,采用有利于景观的可持续土地管理技术,鼓励各种非农业生计战略,升级牲畜饲养系统,并激发可持续能源,这些都是非常紧迫的。

We are happy to announce a new European Journal of Geography (EJG) section titled ‘Geographic Insights in brief’. This initiative complements the new approach of EJG publishing (immediate publication of papers after the end of the review process) The short papers in this section will be published as part of each issue of the journal and will be reviewed only by the editorial team, in order to achieve fast dissemination of new and interesting ideas and applications. This section will accept two kinds of papers: First, papers announcing new ideas, breakthroughs and innovations in all Geographical areas that need to be immediately communicate to all geographers. The authors can later proceed to publish a fully developed traditional paper. Second, brief reports focusing on short, clear and pointed geographical research results and data. These shorter and more digestible items will help geographers to get a better understanding about specific spatial dimensions of environmental, social and economic phenomena and interactions that can feed an ongoing policy discussion with just a small amount of original visual analytics and geographical data. That is, present a smart and successive visualization or datasets, such as cartograms, mental maps, web-GIS platforms, real-time geographies and so on. This process provides new opportunities for intellectual communications and benefits for both researchers and practitioners to present new theoretical and empirical findings from new research and/or innovative geospatial applications. This new EJG section follows the trend in contemporary scholarship on geography to provide open access, inclusive and flexible platforms that express new, vibrant and exciting ideas. The requirements for the new series in EJG are: 1. Scope: European topics in human or physical geography, using cartography, GIS, remote sensing, quantitative or qualitative methods. 2. It includes one main idea or one research question, a reproducible method and one single map and up to two extra figures or/and tables. 3. It has an abstract of 100 words, three to six keywords and one or two research highlights. 4. It has a total word limit of around 1.000-2.000 words (including the main text, figures, tables and references). 5. Maps should comply with the usual cartographic and semiotic rules 6. Data and/or Code should be available on currently available repositories (e.g., Figshare, Mendeley data, Github, CRAN, Dataverse etc.) We welcome research contributions in the scientific fields of geography, planning, sociology, regional science, health, history, engineering, informatics, architecture. For any questions, please write to the editorial team (editor@eurogeojournal.eu) to discuss intended submissions.
我们很高兴地宣布一个新的欧洲地理杂志(EJG)章节,题为“地理见解简介”。这一举措是对EJG出版(审稿结束后立即发表论文)新方法的补充。该部分的短论文将作为每期期刊的一部分发表,仅由编辑团队进行审稿,以实现新的有趣的思想和应用的快速传播。本部分将接受两种类型的论文:一是在所有地理领域发表新的思想、突破和创新,需要立即与所有地理学家交流的论文。作者随后可以继续发表一篇完全发展的传统论文。二是简要报告,重点介绍简短、清晰、有针对性的地理研究成果和数据。这些短小易懂的条目将帮助地理学家更好地理解环境、社会和经济现象以及相互作用的特定空间维度,这些维度可以为正在进行的政策讨论提供少量的原始视觉分析和地理数据。也就是说,呈现一个智能和连续的可视化或数据集,如地图,心理地图,web-GIS平台,实时地理等等。这一过程为知识交流提供了新的机会,并有利于研究人员和实践者从新的研究和/或创新的地理空间应用中提出新的理论和实证结果。这个新的EJG部分遵循当代地理学术的趋势,提供开放获取,包容和灵活的平台,表达新的,充满活力和令人兴奋的想法。EJG对新系列的要求是:1。范围:欧洲人文或自然地理主题,使用制图,地理信息系统,遥感,定量或定性方法。2. 它包括一个主要思想或一个研究问题,一个可重复的方法,一个单一的地图和最多两个额外的数字或/和表格。3.它有一个100字的摘要,三到六个关键词和一两个研究重点。4. 全文字数限制在1000 - 2000字左右(包括正文、图表、表格和参考文献)。5. 地图应符合通常的制图和符号学规则。数据和/或代码应该在当前可用的存储库(例如,Figshare, Mendeley数据,Github, CRAN, Dataverse等)上可用。我们欢迎在地理,规划,社会学,区域科学,卫生,历史,工程,信息学,建筑等科学领域的研究贡献。如有任何问题,请写信给编辑团队(editor@eurogeojournal.eu)讨论拟提交的内容。

Exploring Urban Fear of Crime using Unsupervised Classification - The Case of Athens 用无监督分类探讨城市对犯罪的恐惧——以雅典为例
Q1 Social Sciences Pub Date : 2022-05-01 DOI: 10.48088/ejg.t.sta.13.2.127.138

This publication examines whether urban landscapes, exhibiting different spatial and thematic characteristics, can affect the fear local residents feel about crime. The purpose of this research is therefore to explore the correlation of the fear of crime in modern cities with urban, environmental and social characteristics. In order to verify this postulation, the Municipality of Athens was set as study area and a wide questionnaire-based survey was conducted. A dedicated web platform (http://www.fearofcrime.com/) was employed to collect, analyse and visualize crowd fear experiences and their spatial distribution. Over 900 participants have contributed relevant data to be further explored. In order to meet the above objective and facilitate the process, the respondents and their answers were grouped into clusters via unsupervised classification. The variables were formed by all respondents’ answers and the k-means algorithm was used. From this process, groupings of a certain number of clusters emerged. The distribution of each cluster was determined on the seven City Districts of the Municipality of Athens, which were used as spatial reference units, revealing the largest and smallest concentrations. Thus emerged the image of how the phenomenon of urban fear of crime is shaped in the different districts of the Municipality of Athens.
这篇文章研究了城市景观,展示了不同的空间和主题特征,是否会影响当地居民对犯罪的恐惧。因此,本研究的目的是探讨现代城市中犯罪恐惧与城市特征、环境特征和社会特征的相关性。为了验证这一假设,我们将雅典市作为研究区域,并进行了广泛的问卷调查。一个专门的网络平台(http://www.fearofcrime.com/)被用来收集、分析和可视化人群恐惧体验及其空间分布。900多名与会者提供了相关数据,有待进一步探讨。为了实现上述目标并促进过程,通过无监督分类将受访者及其答案分组成簇。变量由所有被调查者的答案组成,使用k-means算法。从这个过程中,出现了一定数量的集群的分组。每个集群的分布被确定在雅典市的七个城区,作为空间参考单位,揭示了最大和最小的集中。由此可见,城市对犯罪的恐惧现象是如何在雅典市的不同地区形成的。

Exploring the active and network centralities in Metropolitan Athens: The organic vs. the planned form. 探索雅典都市的活动中心与网络中心:有机形式与计划形式。
Q1 Social Sciences Pub Date : 2022-04-15 DOI: 10.48088/ejg.y.par.13.2.142.160
Yannis Paraskevopoulos
The social, historical and spatial processes that shape the centrality pattern of a city have always been at the core of urban studies that explore the interplay between network configuration, human activities and the planned/formal form of the city. However, there is far limited research dealing with historic metropolitan areas, and exploring these links under a quantitative geospatial approach. In this article, we aim to address this gap by the exploring the different centrality aspects of Metropolitan Athens and more specifically by (a) providing a reproducible methodology for identifying active and network centralities, as defined by land-use pattern and space syntax respectively, (b) exploring the geospatial signature of the planned and organic form of Metropolitan Athens as framed by its institutional spatial framework as well as its active and network centrality, respectively, (c) investigating the role of network centrality, in shaping the existing active centrality pattern. The research results highlighted that the organic patterns are similar with the planned ones, mainly in the central and western part of the study area, whereas in the rest parts considerable differences are encountered. Notably, a study, in a metropolitan area with such extent and diverse characteristics (e.g., urban morphology, land uses), is currently missing from relevant literature. Hence, this work could shed light on urban development issues, revealing meaningful insights on how similar metropolitan cities in the Mediterranean region are assembled. Last, it could function as a valuable input for future planning suggestions.
塑造城市中心模式的社会、历史和空间过程一直是城市研究的核心,这些研究探索了网络配置、人类活动和城市规划/形式之间的相互作用。然而,关于历史大都市地区的研究以及在定量地理空间方法下探索这些联系的研究远远有限。在这篇文章中,我们旨在通过探索雅典大都会的不同中心性方面来解决这一差距,更具体地说,通过(a)提供一种可重复的方法来识别活动和网络中心性,分别由土地利用模式和空间句法定义,(b)探索雅典大都会规划和有机形式的地理空间特征,分别由其制度空间框架及其主动中心性和网络中心性构成,(c)研究网络中心性在塑造现有主动中心性模式中的作用。研究结果强调,有机模式与规划模式相似,主要在研究区域的中部和西部,而在其他部分则存在相当大的差异。值得注意的是,在一个具有如此广泛和多样化特征(如城市形态、土地利用)的大都市地区,目前相关文献中缺少一项研究。因此,这项工作可以揭示城市发展问题,揭示地中海地区类似大都市如何聚集的有意义的见解。最后,它可以为今后的规划建议提供宝贵的投入。

Tourism in the wine region of Central Serbia has been gaining more and more affirmation in recent years. This wine destination offers to tourists a rich wine culture and recreation. Also, as a special supplement to wine tourism, ecotourism is especially promoted, in combination with quality wines with geographical origin. The basic analysis of this study is to identify potential locations for ecotourism activities in the wine region of Central Serbia based on physical-geographical elements (topography, altitude, slope, land use / coverage, diversity, distance from rivers) and socio-economic data (proximity to tourist attractions, distance from major roads and places). The integration of the Geographic Information System (GIS) and the Analytical Hierarchy Process (AHP) greatly facilitates the decision-making process in the assessment of ecotourism activities. As a result of this paper, a map of benefits for the development of ecotourism potentials was highlighted. Very high potential is shown by forest areas that can play a key role in tourism but are not fully used. This analysis helps in two ways: the promotion of ecotourism and viticultural destinations. In particular, in the assessment and implementation for local communities to identify tourism as an opportunity for economic development.
近年来,塞尔维亚中部葡萄酒产区的旅游业得到了越来越多的肯定。这个葡萄酒胜地为游客提供了丰富的葡萄酒文化和娱乐。同时,生态旅游作为葡萄酒旅游的特殊补充,结合具有地理产地的优质葡萄酒,得到了特别的推广。本研究的基本分析是根据自然地理因素(地形、海拔、坡度、土地利用/覆盖、多样性、与河流的距离)和社会经济数据(与旅游景点的接近程度、与主要道路和地点的距离),确定塞尔维亚中部葡萄酒产区生态旅游活动的潜在地点。地理信息系统(GIS)与层次分析法(AHP)的结合,极大地促进了生态旅游活动评价的决策过程。在此基础上,提出了开发生态旅游潜力的效益图。森林地区可以在旅游业中发挥关键作用,但尚未得到充分利用,显示出非常大的潜力。这种分析在两个方面有帮助:促进生态旅游和葡萄栽培目的地。特别是在评估和实施中,为当地社区确定旅游业作为经济发展的机会。

The development of spatial abilities in young children leads to better achievement in STEAM education and in their daily lives. Early interventions have been shown to be highly effective in developing spatial abilities. In this study, the spatial abilities curriculum of the Greek kindergarten is described, and the use of maps is recommended for inclusion in the curriculum. This study examines kindergarten pupils’ spatial abilities at the end of two consecutive preschool years and determines whether attending kindergarten for one or two years succeeded in developing the participating pupils’ spatial abilities and achieving the goals set by the curriculum. Furthermore, it investigates which spatial abilities can be developed to the greatest and lowest degree and whether there is a statistical difference in achievement between age (1 or 2 years of study) and gender. The research sample consisted of 90 pupils from 5 different kindergarten classes; these pupils had attended kindergarten for 1 year (younger children called pronipia in Greek) or for 2 years (older children called nipia in Greek). A questionnaire survey was used to collect data for analysis. It was found that the goals set by the curriculum were not satisfactorily met. Older children, as expected, performed better and there was no statistical difference between boys and girls for the total performance. This paper is part of a wider study that aims to investigate pupils’ spatial abilities. It proposes an effective teaching intervention with the use of two large-scale giant maps and appropriate teaching material to develop kindergarteners’ spatial abilities
幼儿空间能力的发展有助于他们在STEAM教育和日常生活中取得更好的成就。早期干预已被证明在发展空间能力方面非常有效。在本研究中,描述了希腊幼儿园的空间能力课程,并建议在课程中使用地图。本研究考察了连续两年学前班结束时幼儿园学生的空间能力,以确定参加幼儿园一年或两年是否成功地发展了参与幼儿园的学生的空间能力,并达到了课程设定的目标。此外,它还调查了哪些空间能力可以发展到最大程度和最低程度,以及年龄(1或2岁)和性别之间是否存在统计学差异。研究样本包括来自5个不同幼儿园班级的90名小学生;这些学生在幼儿园上了1年(年龄较小的孩子在希腊语中称为pronipia)或2年(年龄较大的孩子在希腊语中称为nipia)。采用问卷调查收集数据进行分析。人们发现,课程设定的目标没有令人满意地实现。正如预期的那样,年龄较大的孩子表现得更好,男孩和女孩在总体表现上没有统计学差异。这篇论文是一项旨在调查学生空间能力的更广泛研究的一部分。提出了一种有效的教学干预方法,利用两幅大比例尺地图和合适的教材来发展幼儿的空间能力

Formal Comparison of Spatial Socioeconomic Units Based on their Typological Properties 基于类型学性质的空间社会经济单位形式比较
Q1 Social Sciences Pub Date : 2022-04-12 DOI: 10.48088/ejg.a.dar.13.2.027.043

Spatial units often serve as a reference to socioeconomic phenomena constituting what is known as spatial socioeconomic units (SSEUs). SSEUs find a wide application in geography. In order to understand and compare different typologies of SSEUs, it is necessary to examine the most important part of their definition which is their properties, mainly spatial but also non-spatial. SSEUs defined in this framework can be qualitatively compared on the basis of their properties using the efficient method of Formal Concept Analysis (FCA). Basic elements of FCA are (a) the Formal context which associates objects and attributes via a relation, (b) the Formal concept or category, which is a collection of objects which share common attributes, (c) the hierarchical relation from a more general to more specialized concepts, and (d) the concept lattice which shows all formal concepts of a formal context. This paper presents an FCA-based comparison of SSEUs typological properties using two indicative examples.
空间单位通常作为构成所谓空间社会经济单位(sseu)的社会经济现象的参考。sseu在地理学中有广泛的应用。为了理解和比较sseu的不同类型,有必要考察其定义中最重要的部分,即它们的性质,主要是空间性质,也有非空间性质。在此框架中定义的sseu可以使用有效的形式概念分析(FCA)方法根据其性质进行定性比较。FCA的基本元素是(a)通过关系将对象和属性联系起来的形式上下文,(b)形式概念或类别,它是具有共同属性的对象的集合,(c)从更一般的概念到更专门的概念的层次关系,以及(d)显示形式上下文的所有形式概念的概念格。本文用两个指示性实例对sseu的类型学性质进行了fca比较。
