The national heritage of Korea is being influenced by various aspects of climate change. The international community has advanced discussions on this through the UNESCO World Heritage Committee, and Korea has strengthened its policy responses and research in the heritage sector since the 2050 carbon neutrality declaration. From a geographical perspective, short-term responses to climate change for national heritage require active utilization of GIS-based spatial information, development of risk assessment tools, interdisciplinary exploration of methodologies for heritage conservation and management, and carbon emission reduction. In the medium to long term, it is important to establish a systematic and cyclical monitoring system, integrate climate change response elements into the heritage system, explore traditional knowledge and sustainable practices, and seek nature-based solutions. Furthermore, based on a placed-based approach, efforts should be made to explore response measures considering the spatial context beyond heritage sites and to consider collaboration with local communities.

The purpose of this study is to see characteristics between successors of family farm business and new immigrant farmers. The differences are assessed through the progression of management techniques in basic management elements, such as human resources, intangible assets, distribution, and sales. The analysis results are as follows. In terms of supporting entities and their roles, the development process of family farm successors shows improvement in sales through circular farming, change of growing/feeding methods, rural convergence industries, online/home shopping, and various certificates, technical information, know-how, and intellectual properties. One the other hand, new immigrant farmers tend to acquire various certificates, technical information, know-how, and intellectual properties for the sales of the products that were made through circular farming, smart farms and rural convergence industries. Consequently, young agricultural successors are building business models as a management strategy on what values to create, how to deliver the value, and how to create income.

In the transformative landscape of the Fourth Industrial Revolution, characterized by rapid and significant technological progress, sustainability in local employment has become a critical issue for policymakers. In this study, we explored specific industrial and demographic characteristics affecting local employment sustainability amid ongoing technological advancements in Korea. Our results show that (1) the local educational level is a key factor for enhancing local employment sustainability, and (2) the proportion of long-term employees in local industries also positively affects sustainability. These results underscore the importance of industry and employment policies that consider the local context. This study is significant in underlining the “future of work” discourse relative to the Fourth Industrial Revolution, offering insights for policymakers, enterprises, and communities aiming to maintain local employment sustainability amid unprecedented technological changes.

This study analyzed the applicability of hydrological indices for identifying tidal flats using remote sensing in the northern region of Gyeonggi Bay on the Yellow Sea coast. Remote sensing, recognized as an alternative to field surveys due to its short survey cycle and cost-effectiveness, is particularly suited for assessing areas with limited accessibility. The high turbidity of the Yellow Sea coast complicates the distinction between tidal flats and water surfaces, necessitating a review of the reliability of methodologies before classifying tidal flats through remote sensing. This research compared globally widely-used hydrological index-based tidal flat classification methodologies, and quantitatively assessed the reliability of each index. The analysis showed that mWRI, a modification of WRI, exhibited higher reliability than other indices. MBWI, with a threshold value close to the standard, demonstrated excellent tidal flat classification performance and is expected to effectively identify tidal flats with minimal researcher intervention across various environments. As remote sensing is effective in accessing restricted areas and efficient in terms of cost and time, it complements field surveys which are useful for accurately determining the maximum extent of tidal flats. Therefore, integrating it with legal survey data, which has a relatively long production cycle and lacks data in some areas, is expected to maximize its advantages.

This study focuses on youngt single-person households as a group that migrates for work, and on gender differences in their size and spatial distribution. The purpose of this study is to examine whether there is a difference in the residential ratio of young single-person households by region and gender, and if so, whether this can be predicted as the characteristics of the labor market in the region. The independent variables are the location coefficients of four industries and city size at the municipal level, and the dependent variable is the residence rate of young female-headed households and young male-headed households, and the results of two spatial regressions are compared. The results showed that local labor market characteristics had more explanatory power in the residence rate of young female- headed households, and the variables with significant relationships differed between the two groups. The location coefficient of the real estate industry has the effect of increasing the residence rate of both groups, and the specialization in professional, scientific, and technical services has a positive but not significant relationship. On the other hand, business facility management, business support, and rental services and city size of 1.4 million or more are only significantly positively related to the share of young women living alone, while the location coefficients of health and social services, which are dominated by young women, are negatively but not significantly related to young women living alone. This difference in results may be due to the characteristics of single-person households that are independent earners from their own jobs, beyond gender differences within young adults. The concentration of young female-headed households in certain occupational groups in metropolitan and large cities suggests that young women may have more limited options in terms of occupation and location for stable migration independence.

Large wildfires have been increasingly destructive around the world in the recent decades. To reduce the damage caused by the wildfires, it is necessary to explore the factors amplifying wildfires based on a geographical perspective with local topographical and synoptic climatological factors. In this study, we analyzed the spatiotemporal patterns of spring wildfires in the Yeongdong region over the period of 1979-2023 (45 years) and identified the integrated climatological processes associated with the wildfires. By analyzing the spatiotemporal associations between the continuous long-term Fire danger index and climatic variables from ERA5 climate reanalysis data, it was found that the increase in temperature over the south- central Eurasia enhanced the geopotential height in the mid- to upper-troposphere through the thermal expansion of the atmosphere, which resulted in the northwesterly winds blowing over the Korean Peninsula. These atmospheric thermodynamic processes induced the anomalous pressure pattern of western-High and eastern-Low, respectively, centered over south-central Eurasia and northeastern East Asia, which strengthened the northwesterly winds. At the same time, descending wind anomalies from the upper atmosphere over eastern China and the Yellow Sea have merged into the northwesterly winds in the lower atmosphere. Then, as crossed over the Taebaek Mountains, the hot and dry conditions of airflows were amplified in the Yeongdong region due to the Föhn phenomenon. These climatological processes may affect the initiation and spread of wildfires in the Yeongdong region of Gangwon Province, increasing the risk of wildfires. This study is expected to contribute to the forecasting and response to large wildfires, integrating the topography of Yeongdong region along with the synoptic climatology of Eurasia continent, which could reduce the socio-economic costs of natural disasters.

Geosimulation model has been widely used to understand and predict various geographical phenomena (i.e., urban expansion, disease spreads) through an individual-level behaviors, properties and interactions. These models not only serve as conceptual models for intellectual interactions, but they also function as simulation-based policy analysis tools, such as COVID-19 prevention tools. Despite the abundance of research and widespread application of geosimulation in recent years, few studies have been conducted in Korean geographical societies. To this end, this study introduces the fundamentals of geosimulation modeling and its applications to public health, disaster evacuation, urban planning, and transportation. We expect that this paper helps many students and early career scholars to get an improved understanding of geosimulation modeling perse, and enabling them to apply this approach for their won research.
