From Social Simulation to Integrative System Design

As the recent financial crisis showed, today there is a strong need to gain "ecological perspective" of all relevant interactions in socio-economic-techno-environmental systems. For this, we suggested to set-up a network of Centers for integrative systems design, which shall be able to run all potentially relevant scenarios, identify causality chains, explore feedback and cascading effects for a number of model variants, and determine the reliability of their implications (given the validity of the underlying models). They will be able to detect possible negative side effect of policy decisions, before they occur. The Centers belonging to this network of Integrative Systems Design Centers would be focused on a particular field, but they would be part of an attempt to eventually cover all relevant areas of society and economy and integrate them within a "Living Earth Simulator". The results of all research activities of such Centers would be turned into informative input for political Decision Arenas. For example, Crisis Observatories (for financial instabilities, shortages of resources, environmental change, conflict, spreading of diseases, etc.) would be connected with such Decision Arenas for the purpose of visualization, in order to make complex interdependencies understandable to scientists, decision-makers, and the general public.Comment: 34 pages, Visioneer White Paper, see http://www.visioneer.ethz.c

How the War in Ukraine Affects Food Security

The war in Ukraine has caused severe disruption to national and worldwide food supplies. Ukraine is a major exporter of wheat, maize, and oilseeds, staples that are now suffering a war-triggered supply risk. This paper describes the background of the problem and illustrates current trends by outlining some of the measures that may be deployed to mitigate the conflict’s impacts on achieving SDG 2 (Zero hunger), especially focusing on ending hunger, achieving food security, improving nutrition, and promoting sustainable agriculture. In order to understand the main research strands in the literature that are related to food security in the context of wars, the authors adopted a bibliometric literature review based on the co-occurrence of terms technique, conducted with 631 peer-reviewed documents extracted from the Scopus database. To complement the bibliometric assessment, ten case studies were selected to narrow down the food insecurity aspects caused by the war in Ukraine. The co-occurrence analysis indicated four different thematic clusters. In the next stage, an assessment of the current situation on how war affects food security was carried out for each one of the clusters, and the reasons and possible solutions to food security were identified. Policy recommendations and theoretical implications for food security in the conflict context in Ukraine were also addressed

Urban metabolism and land use modeling for urban designers and planners: A land use model for the Integrated Urban Metabolism Analysis Tool

Predicting the resource consumption in the built environment and its associated environmental consequences (urban metabolism analysis) is one of the core challenges facing policy-makers and planners seeking to increase the sustainability of urban areas. There is a critical need for a single integrated framework to analyze the consequences of urban growth and eventually predict the impacts of sustainable policies on the urbanscape. This dissertation presents the development of an Integrated Urban Metabolism Analysis Tool (IUMAT) – an analytical framework that simulates urban metabolism by integrating urban subsystems in a single comprehensive computational environment. It reviews the existing literature on urban sustainability, urban metabolism, as well as introducing the general framework for IUMAT. IUMAT uses three separate models for quantifying environmental impacts of land-use transition, consumption of resources, and transportation. This work outlines the development of IUMAT Land-Use Model that uses Remote Sensing, GIS, and Artificial Neural Networks (ANNs) to predict land use change patterns. By using Density-Based Spatial Clustering and normal equations, this dissertation introduces a method for generating building-form variables from Light Detection and Ranging (LIDAR) data, which can be used as a new determinant factor in land-use change modeling. The proposed Land-use Model, within IUMAT or other analytical models, can be useful to local planning officials in understanding the complexity of land-use change and developing enhanced land-use policies

The role of social capital and community ties in rebuilding livelihoods of displaced households in peri-urban areas of Ho Chi Minh City

This research explores livelihood issues that emerged from the process of urban development in Ho Chi Minh City, Vietnam. To understand the key determinants and consequences of livelihood strategies, we modified the sustainable livelihoods framework to guide analysis of data from a survey of 242 households interviewed in August 2013. Indicators related to social capital, livelihood resources and economic activities, and the community field were used to assess possible effects and associations with livelihood outcomes of resettled households. The results indicate that households with more extensive social networks have higher level of employment and income and less significant economic shocks. For government-supported households, the perceived affordability of basic needs was associated with higher household income, and food security was associated with higher value of household assets. For self-resettled households, the perceived affordability of basic needs was associated with higher value of household assets, and food security was associated with both higher household income and asset value. Regarding the community field indicators, improved economic conditions and well-being were both associated with higher levels of community participation and higher perceived quality of neighboring among government-supported households. For self-resettled households, length of residence emerged as a significant predictor of improved economic conditions and well-being. Thus, building community social ties with family, friends, and organizations is an essential part of successful household economic and social development strategies

Marketing in the public sector—benefits and barriers: a bibliometric study from 1931 to 2020

The global economy has brought economic and social changes that have led organizations to extend their vision beyond consumer and business markets. Particularly, in the marketing of public sector (MPS), the extant theoretical foundations require more comprehensive investigations not only into the main topics researchers have looked into the past, but also into the new challenges they will face in the future. Thus, the purpose of this study is to provide a thorough a bibliometric overview of the theoretical framework and to identify benefits and barriers of marketing in the public sector. We provide an overview of the theoretical framework and identify the benefits and barriers of marketing in the public sector through a bibliometric study. To achieve this objective, a systematic literature review was conducted of 3926 articles from 1931 to 2020. The results allowed the identification of four main theoretical clusters: educational, public health, social economics and urban politics. It also offered benefits and barriers in the context of MPS. Conclusions and implications to the academia and managers are drawn. Future research opportunities are also provided.info:eu-repo/semantics/publishedVersio

Focusing on the case analysis of advanced smart ports

학위논문(석사) -- 서울대학교대학원 : 행정대학원 글로벌행정전공, 2023. 2. Lee, Soo-young.본 연구에서는 최근 각광받고 있는 스마트 항만의 개념과 항만 경쟁력과의 관계를 고찰해 보고, 선진 스마트 항만에 대한 다각적인 분석을 통해 우리나라 스마트 항만 발전 방향에 대한 시사점을 도출하고자 하였다. 이를 위해 A. Molavi 외의 연구에서 확립된 스마트 항만 평가 척도의 4가지 측면, 운영측면(Operation), 환경측면(Environment), 에너지 측면(Energy), 그리고 안전과 보안 측면(Safety & Security)의 분석틀을 활용하여 스마트 항만 개발과 발전에 가장 앞선 네덜란드의 로테르담 항만과 독일의 함부르크 항만의 정책 분석을 시도하였다. A. Molavi 외의 연구는 측정 가능한 스마트화 지수를 발전시켜 각 항만의 스마트화 정도를 가늠하고 장단점을 파악할 수 있게 하기 위한 취지에서 개발되었다. 하지만 본 연구에서는 스마트 항만의 평가 척도를 활용하되 질적인 분석으로 접근하여 정책 활용 측면에서 유용한 시사점을 도출하는데 목적을 두었다. 또한 동일한 틀을 활용하여 현재 부산 컨테이너 터미널의 스마트 항만 발전 계획을 분석하고 발전방향 설정에 도움을 주고자 하였다. 우선 운영 측면에서 선진 스마트 항만들은 항만 내 하역 전 과정의 완전 자동화를 달성하였고, 이에 그치지 않고 항만 내 모든 과정을 4차 산업혁명의 첨단 기술들을 활용하여 무인화와 효율화를 추구하였다. 이 과정에서 A.I, IoT, 블록체인 등 4차 산업혁명의 핵심 기술들을 적극 활용하여 항만의 전체적인 모습을 변화시켜 가고 있으며, 비용절감과 생산성 증대 등 직접적인 효과뿐만 아니라 글로벌 물류의 핵심 구심점으로써 스마트 항만의 가능성을 발전시켜 나가고 있다. 이를 통해 항만 경쟁력 향상은 물론 물류 포털로써의 지위를 선점하기 위한 경쟁도 심화되고 있다. 환경 측면에서는 친환경 항만에 대한 관심이 증대되고 있다. 항만은 더 이상 도시와 분리되어 존재하는 독립된 영역이 아닌, 인접 도시 주민들과 상호 영향을 주고받으며 발전하는 호혜적인 관계를 구축해야 한다는데 공감대가 형성되고 있다. 이를 위해 그동안 항만 활동을 통해 야기되었던 환경 오염 문제를 줄이고 지역사회에 기여하기 위한 노력들이 활발히 진행되고 있다. 전력에 기반한 친환경 하역장비로 대체하고, 선박의 연료를 친환경 연료로 전환하는 노력이 진행 중이다. 항만 내 유휴부지를 활용해 신재생에너지를 발전하고 인근 지역에 공급하는 방안과, 항만의 환경 문제를 IoT 기술을 활용하여 실시간으로 감시하고 공유하는 시스템을 구축하여 항만의 지속 가능한 발전을 의도하며 탄소 중립 사회로의 진전에 중요한 역할을 자처하고 있다. 에너지 측면에서는 스마트 항만이 미래 수소 사회의 핵심 공급 기지가 될 전망이다. 해상 물류와 육상 물류가 결합되는 기능적 이점을 활용하여 수소의 생산과 저장, 분배 등 수소 경제의 핵심 인프라를 항만 내 구축하고 항만 기능과의 결합을 시도하고 있다. 이를 위해 선진 항만들은 대규모 파이프 라인을 건설하는 프로젝트들을 진행하며 미래를 준비하고 있다. 안전과 보안 측면에서는 항만이 첨단 기술 활용의 경연장이 되고 있다. 항공 및 해상, 수중 드론 등 첨단 장비들을 활용하여 드넓은 항만을 가상 현실세계인 트윈 타워에 이식하고 인공지능에 의한 실시간 관리 감독이 가능한 시스템이 구축되고 있다. 항만 내 하역작업의 무인화는 안전사고의 위험을 획기적으로 줄일 수 있을 뿐만 아니라, 사각 지대가 없는 관리 감독도 가능해져 항만 내 재난사고와 밀입국 등의 문제를 근본적으로 변화시킬 것으로 기대되고 있다. 하지만 선진 스마트 항만에서 추구하는 근본적인 방향은 세계 물류의 핵심 포털을 구축하는 것이며 이를 위해 항만의 역할은 기존의 지역적인 한계를 넘어 기능적으로 그리고 물리적으로 팽창하고 있다. 우리나라의 경우 일찍이 자동화 항만의 발전을 시작한 유럽 항만은 물론 인근 중국과 싱가포르의 자동화 항만과 비교해도 뒤쳐지고 있는 것이 현실이다. 이를 만회하기 위해 중앙 정부 차원에서 스마트 해상물류체계 구축 전략을 수립하고 2030년 스마트 항만의 본격적인 운영을 계획하고 있다. 하지만 본 계획은 전반적인 물류 기능 중 하위 요소로 스마트 항만을 인식하고 있으며, 이는 스마트 항만을 자동화 항만이라는 좁은 측면에서만 바라보고 있는 것으로, 항만의 미래 잠재력에 대한 선진 항만들의 인식과는 큰 차이가 있다고 하겠다. 또한 스마트 항만의 발전 과정에서 민간 기업과 항만 이해관계자들이 적극적으로 참여하고 협력하여 스마트 항만의 모습을 그려가는 선진 항만과는 달리 우리나라의 경우 여전히 정부 주도 발전 방식을 고수하고 있으며, 가장 주도적인 역할을 해야 할 항만 공사들의 역할이 미미한 것은 한계라고 하겠다. 그리고 향후 탄소 중립 사회로의 이행의무 등 환경적인 문제와 친환경 에너지로의 전환이 중요시되고 있는 시점에서 이에 대한 근본적인 전환계획이나 항만의 새로운 역할에 대한 고민이 부족한 것도 비교 연구를 통해 도출할 수 있었다. 유럽의 항만들과는 달리 수소 경제로의 이행에 있어 항만의 핵심적 역할이 빠져 있다는 것은 스마트 항만에 대한 인식 부족에서 비롯된 것으로 보이며 이에 대한 정책적 개선이 필요한 것으로 보인다.This study examines the relationship between the concept of smart ports and port competitiveness, which have recently been in the spotlight, and attempts to derive implications for Korea's smart port development direction through various analysis of advanced smart ports. To this end, this research attempted to analyze the policies of Rotterdam Port in the Netherlands and Hamburg Port in Germany, which are most advanced in smart port development and development, using the analysis framework of four smart port evaluation measures established in A. Molavi et al. In terms of operation, advanced smart ports achieved complete automation of the entire loading and unloading process in the port, and not only this, but all processes in the port were pursued for unmanned and efficient use of the advanced technologies of the 4th Industrial Revolution. In terms of the environment, interest in eco-friendly ports is increasing. There is a consensus that ports should no longer be independent areas that exist separately from cities, but should establish reciprocal relationships that interact and develop with residents of neighboring cities. In terms of energy, smart ports are expected to become a key supply base for the future hydrogen society. Taking advantage of the functional advantages of combining marine logistics and land logistics, the core infrastructure of the hydrogen economy, such as hydrogen production, storage, and distribution, is built in ports and attempted to combine them with port functions. In terms of safety and security, ports are becoming a competition for the use of advanced technology. Using high-tech equipment such as aviation, sea, and underwater drones, a system that allows real-time management and supervision by artificial intelligence is being established by transplanting a wide port into a virtual reality twin tower. In the case of Korea, the reality is that it is lagging behind not only European ports that started the development of automated ports early but also automated ports in neighboring China and Singapore. To make up for this, the central government has established a "smart maritime logistics system construction strategy" and plans to operate smart ports in earnest in 2030. However, this plan recognizes smart ports as a sub-factor of the overall logistics function, which only looks at smart ports in the narrow aspect of automated ports, which is very different from advanced ports' perceptions of the future potential of ports. In addition, unlike advanced ports in which private companies and port stakeholders actively participate and cooperate in the development of smart ports, Korea still adheres to the government-led development method, and the role of port authorities to play the most leading role is insignificant. In addition, at a time when environmental problems such as the obligation to transition to a carbon-neutral society in the future and the transition to eco-friendly energy are becoming important, this comparative study was able to derive the lack of concern about the fundamental transition plan or the new role of ports. Unlike ports in Europe, the absence of a key role in the transition to a hydrogen economy seems to stem from a lack of awareness of smart ports, and policy improvements are needed.Chapter 1.

Characterizing the polycentric spatial structure of Beijing Metropolitan Region using carpooling big data

Polycentric metropolitan regions are a high-level urbanization form characterized with dynamic layout, fuzzy boundary and various human activity performances. Owing to the complexity of polycentricity, it can be difficult to understand their spatial structure characteristics merely based on conventional survey data and method. This poses a challenge for authorities wishing to make effective urban land use and transport policies. Fortunately, the presence and availability of big data provides an opportunity for scholars to explore the complex metropolitan spatial structures, but there are still some research limitations in terms of data use and processing, unit scale, and method. To address these limitations, we proposed a three-step method to apply the carpooling big data in metropolitan analysis including: first, locating the metropolitan sub-centers; second, delimiting the metropolitan sphere; third, measuring the performance of polycentric structure. The developed method was tested in Beijing Metropolitan Region and the results show that the polycentric metropolitan region represents a hierarchical regional center system: one primary center interacting with seven surrounding secondary centers. These metropolitan centers have a strong attraction, which results in the continuous expansion beyond the administrative boundary to radiate more adjacent jurisdictions. Furthermore, the heterogeneity of human activity performance and role for each regional center is remarkable. It is necessary to consider the specific role of each sub-center when making metropolitan transport and land use policies. Compared with previous studies, the proposed method has the advantages of being more reliable, accurate and comprehensive in characterizing the polycentric spatial structure. The application of carpooling big data and the proposed method would provide a novel perspective for research on the other metropolitan regions

Perspectives on Dual-Purpose Smart Water Power Infrastructures for Households in Arid Regions

In hot arid climates, freshwater and power are produced simultaneously through seawater desalination since these regions receive little rainfall. This results in a unique urban water/power cycle that often faces sustainability and resilience challenges. Elsewhere, such challenges have been addressed through smart grid technologies. This chapter explores opportunities and initiatives for implementing smart grid technologies at household level for a case study in Qatar. A functional dual-purpose smart water/power nanogrid is developed. The nanogrid includes multiloop systems for on-site water recycling and on-site power generation based on sustainability concepts. A prototype dual-purpose GSM-based smart water/power nanogrid is assembled and tested in a laboratory. Results of case study implementation show that the proposed nanogrid can reduce energy and water consumptions at household level by 25 and 20%, respectively. Economic analysis shows that implementing the nanogrid at household level has a payback period of 10 years. Hence, larger-scale projects may improve investment paybacks. Extension of the nanogrid into a resilient communal microgrid and/or mesogrid is discussed based on the concept of energy semantics. The modularity of the nanogrid allows the design to be adapted for different scale applications. Perspectives on how the nanogrid can be expanded for large scale applications are outlined

Sustainable Smart Cities and Smart Villages Research

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms. [There is ever more research on smart cities and new interdisciplinary approaches proposed on the study of smart cities. At the same time, problems pertinent to communities inhabiting rural areas are being addressed, as part of discussions in contigious fields of research, be it environmental studies, sociology, or agriculture. Even if rural areas and countryside communities have previously been a subject of concern for robust policy frameworks, such as the European Union’s Cohesion Policy and Common Agricultural Policy Arguably, the concept of ‘the village’ has been largely absent in the debate. As a result, when advances in sophisticated information and communication technology (ICT) led to the emergence of a rich body of research on smart cities, the application and usability of ICT in the context of a village has remained underdiscussed in the literature. Against this backdrop, this volume delivers on four objectives. It delineates the conceptual boundaries of the concept of ‘smart village’. It highlights in which ways ‘smart village’ is distinct from ‘smart city’. It examines in which ways smart cities research can enrich smart villages research. It sheds light on the smart village research agenda as it unfolds in European and global contexts.
