Environmental protection issues and the monitoring of pollution, especially for the largest cities in Asia, are becoming increasingly prominent factors for inclusive urban planning of public open spaces. Recently, a walkability concept was implemented in many cities, and in 2016 it became a campaign direction for development in Seoul. This paper considers conditions of implementation for the walkability concept, using examples of pedestrian walkway-making initiatives, and regeneration of existing walkways along water streams in urban case studies in Seoul, South Korea. The role of nature-based solutions was considered in relation to aesthetics, and social and environmental characteristics (e.g., air pollution, oxygenation through greenery) obtained through literature reviews for the case studies. Considering the complexity of the situation, with factors such as Air Quality Index (AQI) warning conditions, and the general positive impact of walkability on enhancing a healthy life style and social interaction and on reducing congestion, this study contributes to the discussion on walkability, and the importance of nature-based urban regeneration projects for densely populated areas in cities. The results of particular cases in this paper suggest the need for careful monitoring and consideration of various factors for urban regeneration walkable design projects.

Since 2001, South Korea has experienced sustained lowest-low fertility. This phenomenon has persisted despite the implementation of several social policies aimed at increasing fertility rates. The purpose of this study was to quantitatively analyze the demographics, socioeconomics, housing situation, residential environment, and housing expectation of newlyweds in terms of their fertility intentions in South Korea (within 5 years of marriage) in order to help the development of more effective housing policies. We extracted the factors on the basis of fertility theories and previous related studies and identified differential characteristics of the impact on fertility intentions for the first and for additional child(ren). The results show that fertility intention was higher in non-metropolitan and rental households. There was also a significant relationship between the anticipated period of a home purchase and fertility intention. In particular, for one-child families, the second child fertility intention was significantly affected. In conclusion, we quantitatively confirmed various factors that significantly impact the fertility plans of newlyweds. We suggest that the government implements housing policies on the basis of economic stability, the number of children, and the residential environment of newlywed couples.

In 2018, the South Korean government began promoting a “livelihood-improving” social overhead capital policy based on the concepts of an inclusive city, smart shrinkage, and the balanced development of metropolitan and provincial cities. Based on a review of the extant literature and relevant policies from South Korea, this study explores this policy’s implementation and makes some suggestions for its sustainability. This study compares the current state of South Korea’s urban facilities’ and the balance of their supply between metropolitan and provincial cities. To discern which type of facility central and local governments should prioritize, this study conducts a stepwise regression analysis and identifies which preexisting facilities influence the facility type proposed by the current policy. Results show that South Korea’s living infrastructure is well distributed among metropolitan and provincial cities. However, urban planning shows little consideration for minimizing the distance between facilities and residential zones. In terms of facility types, the supply of education and local community facilities was adequate throughout the country, while culture and art facilities were inadequate. In metropolitan cities, the supply of sports and leisure facilities was insufficient.

Recently, Korea has become increasingly interested in unused, but possibly useful energy resources, due to the world-wide controversy over nuclear power and limitations in renewable energy production. Among these unused resources, the water that is produced in our surroundings is available as a potential energy source for heating, cooling and domestic hot water. This water is relatively stable on the supply side, available as a high-efficiency source in all seasons, and is continuously replenished without polluting the environment. This paper analyses the energy savings generated based on the actual use of a sustainable heating and cooling system that operates using the water escaping from a nearby building. The results indicate the value of protecting the environment as well as reducing energy consumption and associated costs.

Minimum housing standards aim to safeguard housing rights and enhance residential conditions. Governments develop housing policies, including provision, preservation, and support for welfare programs, guided by the status of households below these standards. Growing nations commonly utilize this approach to decrease the proportion of households not meeting these criteria. In South Korea, the ratio of households below these standards was 4.5% in 2021, down from 16.6% in 2006, as indicated by the initial Korea Housing Survey. However, this downward trend has stalled over the past decade. With the 2004 and 2011 revisions, the standards have been effective for 12 years, yet no longer mirror current housing realities due to ongoing improvements. This study aimed to propose enhancements to Korea’s minimum housing standards. Through analyzing laws, prior research, present household statuses, international cases, and expert insights, recommendations emerged. Categorizing households by size, we developed precise standards covering area, facility, and location aspects. These new standards led to an 8.4% non-compliance rate in 2021. This research’s findings anticipate aiding the revision of minimum housing standards, formulating pragmatic policies for enhancing residential conditions in line with present situations.

The Seoul Metropolitan Government has initiated projects to create campustowns to fully utilize university infrastructure. In this study, the first campustown project implemented in South Korea, Korea University-Anam Campustown Project, was evaluated to develop sustainable growth plans. Universities have useful infrastructure in terms of facilities, equipments, and human resources. There is a recent focus on breaking down boundaries between universities and communities to share this useful infrastructure. The methodology of this study is as follows. Primary indicators of win-win growth plans were identified by literature reviews and case studies. The indicators were applied to the target area by evaluations of the status of the area, SWOT analysis, collection of stakeholders’ views, and in-depth interviews. A commercialization plan was verified, while focusing on the project budget, feasibility, and administrative procedure. In total, 34 projects spanning five sectors (i.e., start-up, residence, culture, sharing with communities, and sustainability) were identified. Finally, measures to secure project implementation capacities and a master plan to improve the sustainability of this project were suggested. The results of this study are expected to contribute to the creation/development of similar projects at other universities in Korea.
