Although many people affected by COVID-19 suffer from some form of psychological distress, access to proper treatment or psychosocial interventions has been limited. This study aimed to examine the feasibility and preliminary effects of a therapeutic gardening program conducted during the COVID-19 pandemic. The program consisted of 30 sessions and was conducted at 10 nationwide sites in Korea from June to November 2021. Mental health and well-being were assessed using the Mental Health Screening Tool for Depressive Disorders, Mental Health Screening Tool for Anxiety Disorders, Engagement in Daily Activity Scale, brief version of World Health Organization Quality of Life, and Mindful Attention Awareness Scale. Cohen’s d value was calculated for the effect size, and a multilevel analysis was used to determine the longitudinal effects of therapeutic gardening. The effect sizes for depression, anxiety, daily activities, quality of life, and mindfulness were 0.84, 0.72, 0.61, 0.64, and 0.40, respectively. Multilevel analyses showed that all five mental health variables improved significantly over time as the therapeutic gardening program progressed. Therapeutic gardening is promising and applicable as a nature-based intervention to improve the mental health of individuals experiencing psychological distress especially in the COVID-19 pandemic.

With the increasing interest in integrative sustainable development, there has been a strong need for a landscape sustainability assessment tool independent from the existing green building rating system. This study aimed to establish an assessment model to objectively evaluate landscape sustainability using an analytic hierarchy process (AHP). Through an extensive literature review and expert survey, an initial list of assessment items was derived and used to set up an AHP model. An AHP survey with landscape architects and architects/engineers was then conducted to determine the importance of the assessment factors. In addition, the model was applied to three projects that were previously certified by a green building rating system in Korea. The AHP results showed that “site context” ranked as the most important factor of landscape sustainability followed by “soil and vegetation,” “maintenance,” “water,” “health and wellbeing,” and “materials.” Among the 20 assessment factors, “monitoring plan” was evaluated as the most important index, followed by “protection of cultural heritage” and “long-term management plan.” Landscape architects evaluated “soil and vegetation” as the most important in the assessment, while the engineers/architects group rated “site context” as the most important. When tested by applying them to the previously certified projects, the developed factors provided more objective and detailed information on landscape sustainability.

The purposes of this study are to identify assessment indices for evaluating the environment for elderly pedestrians and to compare the pedestrian environment surrounding senior welfare centres among large, mid-size, and small cities. To that end, a set of assessment indices and weighted values were decided and field assessments were carried out in seven cities in Gyeonggi province. Research methods such as reviews of pedestrian assessment tools, field assessment, and an analytic hierarchy process survey were conducted. The comparative analysis of the assessment results suggests the following policy implications. First, Aesthetics including attractive views, tree shade, and building facades was found to be important, let alone Safety, which represents the presence of path and traffic control devices. Second, there is a considerable discrepancy in the pedestrian environment surrounding senior welfare centres between large cities and mid-to-small cities, which pose a serious impediment to both balanced urban development and senior citizens’ welfare. Third, it is important to develop easy-to-use assessment tools that are customized to the domestic pedestrian environment to enhance awareness about the local environment, as well as to draw more interest and participation to the improvement of the environment for elderly pedestrians.

This study investigated eco-tour ships at Nakdong estuary, Suncheon wetland, and Goesan and Sanmagi-yetgil, 3 of the 26 ecotourism sites in Korea, by analyzing the characteristics and level of ecotourist satisfaction. The field investigation focused on eco-tour ship image, facilities, landscape observed from eco-tour ship, course, and operations. The results of the satisfaction analysis can be summarized as follows. First, there was no significant difference in satisfaction of eco-tour ship image between Nakdong estuary and Sanmagi-yetgil (p > 0.01), while Suncheon wetland showed a significant difference (p < 0.01). It is assumed that the fact that the ship was built using timber which better suits the natural environment and coastal ecosystem had a positive impact on the visual image. No significant difference in satisfaction with facilities on eco-tour ships was found between Nakdong estuary and Suncheon wetland, while Sanmagi-yetgil showed a significant difference. Second, satisfaction of the landscape observed from the eco-tour ships showed significant differences in the mean scores of landscape evaluation the three target sites: Sanmagi-yetgil (8.40), Suncheon wetland (7.20), and Nakdong estuary (4.67). These values are based on the qualitative evaluation of the landscape as seen from the eco-tour ship. It is presumed to have been influenced by the diversity of the landscape and the width of the river. The eco-tour ship course satisfaction also showed significant differences in the mean scores: Sanmagi-yetgil (7.37), Suncheon wetland (6.57), and Nakdong estuary (5.00). The landscape and tour course evaluations of the respondents seem to be correlated. In particular, the variety of courses available to visitors in Sanmagi-yetgil was relatively high compared to Nakdong estuary and Suncheon wetland. Third, satisfaction analysis for eco-tour ship operations found that Suncheon wetland and Sanmagi-yetgil did not differ significantly in terms of satisfaction (p = 0.634), but Nakdong estuary showed a significant difference. The relatively low satisfaction with the eco-tour ship operation at Nakdong estuary is due to the low scores for eco-tour ship commentary, reservation system, and with the facilities, while it is shown that the operation time as well as the landscape observed from the eco-tour ship and the tour course had a combined influence on satisfaction. In the comparative analysis of the impact of eco-tour ships on ecotourism, Nakdong estuary showed a significant difference. This finding indicates a greater influence of eco-tour ships on ecotourism in Suncheon wetland, Sanmagi-yetgil, and Nakdong estuary. Enhanced ecotourism satisfaction improves the probability of return visits. Thus, there is a need to incorporate the characteristics of ecological resources with well thought out operation and increased functional suitability of eco-tour ships to improve ecotourism satisfaction. The eco-ships in the three places in this paper have elements promoting and enhancing their potential. Our findings showed the satisfaction level of the users with the theme of ecotourism.

Maintaining and improving the ecological soundness and value of Korea’s traditional villages can contribute to their role as tourism resources. This study examined water treatment measures intended to improve the ecological value of one of South Korea’s traditional villages by analyzing the efficiency of water treatment in a pond at the village’s entrance and changes in flora around the village pond. The results demonstrated a statistically significant reduction of non-point pollutant sources flowing from the pond into surrounding farmland. Treatment efficiencies of Total Nitrogen, Dissolved Oxygen, Biochemical Oxygen Demand, and Chemical Oxygen Demand and Total Phosphorus were 75.33, 30.02, 65.52, 59.12 and 78.85 percent respectively. Moreover, changes to the flora around the village pond were analyzed. Prior to the village pond being dug, the flora consisted of a single-species gramineous plant; however, after the village pond was constructed, nine types of aquatic plants were identified, including lotus plants. The flora diversity was increased, with the aquatic plants showing strong growth. This pond function influences the reduction of pollution load for streams outside the village, and distributes the treatment effects of pollution sources that occur inside the village.
