Research on the actual status of Intercultural Garden initiatives in Japan

Zhou Tianshuo, Ichinose Tomohiro

Reports of the City Planning Institute of Japan (The City Planning Institute of Japan) 23 ( 2 ) 152 2024.09

We investigated the current status and role of intercultural gardens in Japan, highlighting their importance in promoting multicultural coexistence amidst a growing foreign resident population. This research aimed to provide a basis for future discourse and action towards a sustainable future for IGs in Japan. We examined case studies from Kariya, Chiryu, and Toyota Cities in Aichi Prefecture and Nagata Ward in Kobe City, focusing on areas with significant numbers of foreign workers. The results showed that IGs facilitate regional diversity and intercultural exchange. Collaboration with local organizations, resource recycling initiatives, and opportunities for multicultural interaction are seen as essential to ensure the sustainability and development of these community spaces.

Ongoing global change makes it ever more urgent to find creative solutions for biodiversity preservation, but prioritizing sites for protection can be challenging. One shortcut lies in mapping the habitat requirements of well-established biodiversity indicators, such as top predators, to identify high-biodiversity sites. Here, we planned site protection for biodiversity conservation by developing a multi-scale species distribution model (SDM) for the raptorial Northern Goshawk (Accipiter gentilis; goshawk) breeding in an extensive megacity region of Japan. Specifically, we: (1) examined the determinants of top predator occurrence and thus of high-biodiversity value in this megacity setting, (2) identified the biodiversity hotspots, (3) validated whether they actually held higher biodiversity through an independent dataset, and (4) evaluated their current protection by environmental laws. The SDM revealed that goshawks preferred secluded sites far from roads, with abundant forest within a 100 m radius and extensive forest ecotones suitable for hunting within a 900 m radius. This multi-scale landscape configuration was independently confirmed to hold higher biodiversity, yet covered only 3.2% of the study area, with only 44.0% of these sites legally protected. Thus, a rapid biodiversity assessment mediated by a top predator quickly highlighted: (1) the poor development of biodiversity-friendly urban planning in this megacity complex, an aspect overlooked for decades of rapid urban sprawl, and (2) the extreme urgency of extending legal protection to the sites missed by the current protected area network. Exigent biodiversity indicators, such as top predators, could be employed in the early or late stages of anthropogenic impacts in order to proactively incorporate biodiversity protection into planning or flag key biodiversity relics. Our results confirm and validate the applied reliability of top predatory species as biodiversity conservation tools.

The Daurian Redstart Phoenicurus auroreus has expanded its breeding distribution in recent years and now breeds in Japan, previously only part of its wintering range. We analyzed the breeding habitat selection of the population at the nest and territory scale in the Kirigamine Highlands, Nagano, Central Japan. At the nesting scale, the birds chose buildings frequently occupied by humans, while at the territory scale, they avoided sites in larger built-up areas. Our findings demonstrate that the breeding habitat selection of Daurian Redstart is influenced by environmental factors at both nest and territory scales.

The shift from automobile-oriented cities to walkable, people-centered cities is underway around the world. In the early 2000s, the Walkable Index was proposed, and many studies have been conducted on the walkability of cities. Many studies have proven that walking has various effects on human health. Increasingly severe global environmental problems and the spread of COVID-19 since the end of 2019 are pushing this urban transformation forward rapidly, moving us toward the construction of integrated sustainable cities on a human scale, such as 15-minute cities. I would like to give an overview of what kind of debate has been going on in the world from the end of the 1990s to the present from the perspective of walking.

Unmanned aerial vehicles as a useful tool for investigating animal movements

Methods in Ecology and Evolution 13 ( 5 ) 969 - 975 2022.05

Determining animal abundance is crucial for assessing the effectiveness of management measures against pest animals. Meanwhile, investigating animal movements has become important for conducting abundance estimations of unmarked animals since the random encounter model (REM) was published. REM is a camera trapping method that derives animal density by using contact ratio between camera traps and targeted animals that randomly move at a certain speed in a given area. However, it requires an independent value, which is animal speed. For investigating animal speed, camera traps with video recording and GPS tagging are the commonly used tools. Unmanned aerial vehicles (UAVs) are currently used in wildlife monitoring to investigate the abundance of target species. It is evaluated as a tool that is non-invasive and suitable for surveys in inaccessible landscapes. Considering these characteristics, we regarded a distant survey using this technology as suitable for investigating animal movements. Therefore, we proposed a method for estimating animal movements using UAVs and conducted a case study that aimed to investigate wild boars' movements. We collected 11 video samples that successfully followed the movements of wild boars from 26 UAV flights in total, and the average speed of their movements derived from all the samples was 1.54 km/24 hr. We found that issues can be improved, including species identification, video sample length, and animal behaviours or activity patterns. On the other hand, our method showed potential for applying to species with specific characteristics in their body size, shape or activity patterns. With improvements in the issues mentioned above, UAVs would become an alternative tool for investigating animal movements.

In this article, we examined the value of the traditional Japanese flood control measure that uses a discontinuous levee (kasumitei). By avoiding the use of flood-prone lowlands for inhabitation and allowing floodwater movement through the kasumitei, the cost of building damage can be reduced, and water supply to wetlands can be increased. The purpose of our study was to quantify flood damage cost reductions and the potential gains for wetland species as part of an ecosystem-based disaster reduction initiative. The study was conducted in the Amano River basin in central Japan. First, we applied a drainage model and calculated the flood damage cost reduction in the floodplain from an evaluation of inundation depth differences. As part of an analysis of potential wetness, we identified areas where 1 m of flooding was predicted in rice paddies near kasumitei. We also quantified a topographic wetness index, the ratio of lowlands, and the ratio of poorly drained soil types, all of which would be beneficial to wetland species. We also investigated land-use change in the area and the relevant financial support framework. The results showed that a simulated closed levee system causes greater inundation and exposure to residents, and the value of paddy areas near kasumitei was calculated to be 43,830 JPY/1000 m2/year at the maximum. Even though the paddies tend to be poorly drained, these areas have been continuously used as paddies for the past century even under development pressure. The economic value and habitat potential of kasumitei levee systems have not been considered as part of any previous flood-management policies. We propose these existing flood control areas to be considered in the financial support framework in the context of river basin and ecosystem-based disaster risk reduction management.

I am researching the Aso region to clarify the multilayered area of the regional circular and ecological sphere and the method for its construction. The largest area is the basin of six class A rivers flowing down from the Aso region as a regional circular and ecological sphere. Approximately two million people live in this basin, and 2.3 million people in the Fukuoka metropolitan area also use its water resource. The population of the Aso area, which is the source of the water, is about 210,000, and it is estimated that the population will be reduced by half by 2050. In the Aso area, there are more than 20,000 hectares of semi-natural grasslands, which play a significant role as a groundwater recharge area. The area of the grasslands is decreasing year by year due to the aging of the people involved in maintaining and managing them, and it is predicted that more than half of the grasslands will be lost by 2050 compared to 2003. To halt the decline in grassland areas, it is necessary to reduce the amount of labor required for burning at the end of winter.

The Impact of the COVID-19 Pandemic on the General Public in Urban and Rural Areas in Southern Japan

Urban and rural areas are situated in contrasting physical and social settings, which influence their levels of exposure as well as their preventive behaviors in response to the COVID-19 outbreak. The study investigated whether there were differences between the areas regarding the levels of difficulty and anxiety felt by the general public during the first wave of COVID-19 in April and May 2020. We conducted an online questionnaire in Fukuoka and Kumamoto Prefecture in southern Japan via a private research company and collected a total of 913 valid responses from individuals whose conditions of employment were affected by the coronavirus outbreak. Although urban areas experienced higher case rates compared to rural areas, ordinal logistic regression analysis revealed no significant differences between urban and rural respondents concerning the level of difficulty in routine life. The daily-life contents which made them feel difficult during the first wave also did not differ largely between the contrasting areas. Urban respondents appeared to have experienced a higher level of difficulty in finding an alternative job, but how respondents found one, if successful, did not differ between urban and rural areas. The area of residence played a role in explaining the level of anxiety toward being infected, especially when the anxiety-related questions involved relationships with neighbors. Rural respondents showed a significantly higher level of anxiety toward causing neighbors trouble and being criticized if infected. Respondents who were better embedded in their communities generally felt more anxious about being infected, regardless of whether they lived in urban or rural areas. Women and respondents with children were more likely affected by abnormal situations caused by the COVID-19 outbreak. Our study highlights the prevailing impact of the COVID-19 pandemic on the general public regardless of whether in urban or rural settings, as well as the potential contribution of social ties among people to protecting communities from infectious pathogens.

Because of COVID-19, our life, including the use of an urban park, drastically changed while we spend time with stay-at-home style. This study aims to find the characteristics of urban park usage during the COVID-19 crisis. We conducted observational surveys in five parks for three months. We revealed how the park use changed due to the opening of playground equipment following the lifting of the state of emergency. We found the demand for the park increased under the state of emergency and the difference in children’s park use between the situation in the emergency state and that in usual. We should reconsider the management of park during the state of emergency based on research.

Hotspots of Agricultural Ecosystem Services and Farmland Biodiversity Overlap with Areas at Risk of Land Abandonment in Japan

Agriculture provides a wide range of ecosystem services and has the potential to contribute to biodiversity conservation. In Japan, many of the resources associated with agroecosystems are threatened by farmland abandonment. Identifying where and to what extent agricultural ecosystem services and farmland biodiversity are affected by farmland abandonment is essential for developing effective strategies to counter the potential loss of these services and the biological communities that support them. Our study aimed to examine how a set of indicators for ecosystem services and biodiversity linked to agroecosystems (proportions of land dedicated to rice production and other agricultural production, proportion of agricultural land on slopes potentially providing landscape aesthetics, proportion of villages promoting rural tourism, and densities of forest edges and irrigation ponds in agricultural land) are distributed at the municipal level across the Japanese Archipelago, and to analyze their spatial patterns in relation to the distribution of farmland abandonment. It was hypothesized that hotspots of agricultural ecosystem services and farmland biodiversity occur in areas at risk of farmland abandonment owing to shared drivers. The cluster analysis identified four distinct ecosystem service bundle types, two of them representing areas specializing in agricultural production, while the other two provided high levels of cultural services and habitats for diverse biological communities. The latter two bundles were located in hilly and mountainous areas and accounted for 58% of rice production, 27% of other agricultural production, 77% of landscape aesthetics, 77% of rural tourism, 64% of forest edges, and 87% of irrigation ponds in Japan. In support of the hypothesis, farmland abandonment was pronounced in these areas, with 64% of recently abandoned fields located where 44% of agricultural land was found. This spatial overlap suggests that substantial losses of ecosystem services and biodiversity may occur if current patterns of farmland abandonment continue. In order to prevent large-scale losses of agricultural ecosystem services and farmland biodiversity, measures to counteract the ongoing abandonment trends should prioritize hilly and mountainous areas, and future studies should further evaluate the multiple functions of agricultural areas to improve policies that aim to ensure sustainable development of rural areas in Japan.
