A Case Study on Smart Water Grid in Incheon, Republic of Korea: How ICT-Enabled Water Management System Affected the Region's Water Quality, Leakage, and Desalination
Virtual Poster Seungjoo Lee, Saebom Jin
Water is a finite and irreplaceable resource. At the same time, it is reusable if well-used and well-managed. This is a case study conducting an in-depth analysis and comprehension on the water management system in Incheon, a city located in Republic of Korea(ROK). This study lies on following reasons and purposes: First, Incheon is the country's first city to establish and operate internet network-based, centralized surveillance and control system for the municipal water management. Second, Incheon is geographically unique, comprised by one mainland located in the Korean Peninsula and an island, Yeongjong-do, where Incheon International Airport is located. This abounded our case study with various cases and case-based solutions and strategies within the case. Third, we evaluated the effectiveness and ICT-enabled new water management system, Smart Water Grid of Incheon by conducting comparative analysis with other cities in Korea, as well as within the city by looking at significance of changes between before and after this ICT-enabled digital systemization. To conduct this analysis, we adopted Analysis of Variance (ANOVA) model to test the before-and-after and across-cities water indicators. Our empirical study on the data from 2012 to 2017 shows some significant changes: improvement in water quality, water leakage reduction, and water desalination across different districts of Incheon. Last of all, we seek to approach various parts of the world, particularly the less-developed yet more water-stressed regions, with this bright case from Incheon to deliver the high possibilities of success in resolving water-related issues when adopting the ICT technologies.
Measuring Climate Change Comparing Public Spaces in the Urban Region of Heidelberg
Poster/Exhibit Session Kathrin Leutz
The major challenge of climate change requires solutions, especially in cities - which are equally responsible for a large amount of the anthropogenic greenhouse effect. Sustainable future models of the modern city are primarily aimed at mitigation, with two essential factors: energy saving and energy efficiency. Municipal infrastructure, health risks for citizens or urban green areas are under the influence of changing weather conditions. Increasing heavy precipitation and overheating are examples that affect all fields of urban action and require adaptation strategies. The main aim of the project consists of the data collection and evaluation of different climate parameters as well as the survey of citizens on the perception of climate change in public areas in Heidelberg. A comparison of sites in the historic old town with newly created areas makes it possible to evaluate the key factors in urban planning in order to generate both, climatic and social benefits.
Cross-cultural Competence in Depopulated Areas: Case Studies of Migrators in Tottori, Japan
Poster/Exhibit Session Shino Koda
Migrators are often welcomed especially in depopulated areas. In this situation, the depopulated areas tackling the population issue through migration policies tend to become multicultural. It is true that increasing the population has positive impact on the communities but the drastic change by becoming multicultural can lead to some problems between migrators from abroad and local residents. As mentioned in the SDGs by UN, it is of importance that we make “cities and human settlements inclusive, safe, resilient and sustainable” based on the concept of “leaving no one behind”. In this context, case studies in Tottori were conducted. Tottori is the least populous prefecture in Japan. It has a population of approximately 570 thousand and its population keeps decreasing. As a measure to revitalize the communities, each municipality in Tottori has launched various migration policies. This paper reveals the characteristics of the relationship between non-Japanese migrators and Japanese local residents in depopulated communities in Tottori focusing on cross-cultural competence. In order to scrutinize this, questionnaires were administered and analyzed. Along with this, semi-structured interviews for both non-Japanese and Japanese residents in Tottori were conducted. Based on the results, this paper discusses the characteristics of the relationship between non-Japanese migrators and Japanese local residents in Tottori and how cross-cultural competence affects their daily life especially at schools and workplaces. In addition, it also suggests a new way of communication which can enhance the relationship toward a sustainable society.
Classification of Ecosystem Damages According to Cause and Effect
Poster/Exhibit Session Kyung Il Lee
Due to the ongoing development-oriented management in Korea, the major preservation areas have been seriously damaged, but the comprehensive status data of the damaged areas have not been established, such as what has been damaged or what kind of damage has occurred. As a result of the lack of national databases on damages, systematic and mid- to long- term ecological restoration projects have not been carried out, and major restoration projects have been conducted indiscriminately according to the necessity. Therefore, it is important to analyze the current status of the damaged areas in the whole country, and to establish a database for each type according to the cause or effect of the damage. In this study, the survey sites are selected for the whole country and a field survey is conducted to investigate the quantitative characteristics such as the extent of damage, damage characteristics, threat factors, land use, and qualitative characteristics such as changes in water quality and soil chemical composition. In addition, we perform literature survey, image data analysis, etc., together with field survey results, classify the damage type of each survey site, and calculate the distribution and area according to each type. The results of this study provide guidance on the classification of the damage type according to the cause and effect of the damage and suggest restoration directions for each type to be helpful for ecosystem restoration projects and policies.
