The recycling of urban green waste generated from urban forests is important in enhancing urban circularity; however, most green waste remains underutilized. An effective way to recycle green waste is composting. Recent studies show the effectiveness of decentralized composting in home and community gardens; however, little is yet known about linkage to commercial urban agriculture, which could play a critical role in urban food supply. This study aims to investigate the community-scale composting system of green waste integrated into commercial farming, using Tokyo as a case study where urban and agricultural land uses are mixed historically. We conducted mailed questionnaire surveys and in-person semi-structured interviews with urban farmers. The results revealed that approximately one-third of professional urban farmers still produced compost from green waste, especially leaf litters, to improve soil quality. They have adapted urbanization by expanding leaf litter sources beyond their own woodlands to various neighboring urban forests within a few kilometers, including parks, schools, and shrines. Although urbanization has drastically changed the tangible landscape, urban farmers have handed down the intangible system for hundreds of years by retrofitting their system. While the system can contribute to reducing green waste and enhancing urban circularity, urban farmers are motivated by economic reasons rather than such environmental reasons. In cities that encompass productive urban landscapes, decentralized composting systems work effectively in commercial urban agriculture due to its geographic proximity of waste supply and demand sites. This study suggests the potential benefits of having urban farms in cities abundant in underutilized organic wastes. Further research is needed on how to scale up waste recycling through urban agriculture to foster urban circularity and sustainability.

Abstract

Urban agriculture is the key to creating healthy cities and developing resilient urban food systems in uncertain times. However, relevant empirical evidence is limited. This study quantitatively verified the association of access to local food through urban agriculture with subjective well-being, physical activity, and food security concerns of neighborhood communities in the context of the COVID-19 pandemic. The target was Tokyo, Japan, where small-scale local food systems are widespread in walkable neighborhoods. We found that diversity in local food access, ranging from self-cultivation to direct-to-consumer sales, was significantly associated with health and food security variables. In particular, the use of allotment farms was more strongly associated with subjective well-being than the use of urban parks, and it was more strongly associated with the mitigation of food security concerns than the use of food retailers. These findings provide robust evidence for the effectiveness of integrating urban agriculture into walkable neighborhoods.

Tokyo is characterized by scattered productive urban landscapes (PULs), such as farmlands, homestead woodlands, and satoyama woodlands, which could potentially promote residents’ physical activity against the backdrop of an aging society. We evaluated the contribution of five types of activities conducted in such locations to promote physical activity in 80 participants through data from accelerometers and activity diaries. Older participants engaged in the activities frequently and for long hours, as well as spent a high percentage of their total energy expenditure on these activities. In particular, energy expenditure in satoyama woodlands averaged approximately-one-third of the national weekly recommendations for older adults. The activities at the allotments varied widely among participants in terms of frequency, activity hours, and energy expenditure, which is desirable because it allows participants to remain involved even when they are older. The results of the generalized linear mixed models showed that total daily energy expenditure was significantly higher on workdays, ranging from 1.18 to 1.36 times of non-workdays by type of activity. The hourly energy expenditure in PULs was comparable to that in public parks, compensating for the small park area in Tokyo, even though it ranged from the highest at homestead woodlands to the lowest at satoyama woodlands. Local governments that wish to support public health and conservation of urban green spaces could encourage residents to use PULs that remain within urban areas. In aging and shrinking cities, they could gain the same benefits by converting poorly managed land to PULs.

We used publicly available land-cover datasets (1921, 1947, 1976, 1992, 2001, 2006, 2014) to assess land-cover change on Babeldaob Island, Republic of Palau. Land-cover data were organized, classified, and summarized by area and percentage of island cover for forest, mangrove, non-forest vegetation, and non-vegetation. Japanese colonial administration of the island between 1921 and 1947 included industrial mining and agriculture, which reduced total non-mangrove forest cover by 16%. Temporal vegetation cover dynamics from 1947 through 2014 indicate unassisted forest regeneration of 12% with a concomitant decrease in non-forest vegetation including abandoned agriculture, the majority of which happened by 1976. Mangrove cover appears to have remained stable throughout the 93 year study period. Ground-truth observations showed the highest rates of vegetation cover change since 1976 for non-vegetated areas, followed by marsh and swamp forest. The proportion of non-vegetated cover increased at least twofold after WWII, with at least half comprising roads. Contrary to other tropical geographies, we saw forest expansion following completion of a major perimeter road. However, the larger landscape is permeated by dynamic forest edges subject to wildfire and other land-use disturbances.

The coronavirus disease 2019 (COVID-19) pandemic of 2020 drastically changed urban lifestyles. Workers were forced to minimize commuting to their workplaces, older adults were banned from using meeting facilities, and children were prohibited from going to school. The consequent lack of exercise, accumulated stress, and reduced well-being are likely to have become problems, which may be improved by using urban green spaces (UGS). This study clarified the characteristics of users of UGS in Tokyo during the COVID-19 pandemic, focusing on telecommuters, older adults, and families with children. An online questionnaire survey was conducted among Tokyo residents, and 3085 responses were obtained. A binomial logistic regression analysis was conducted with the use and evaluation of UGS as the objective variables. The results showed that older adults and families with children who had been using UGS before the pandemic and telecommuters who newly started using UGS during the pandemic used UGS differently. Older adults and families with children tended to use small parks and appreciated human connections. Telecommuters often used greenways, temples, and shrines, valuing stress-reducing functions. Given that a changing lifestyle brings new UGS users new preferences, urban planners should consider that UGS require change with the time.

Abstract

Modern dietary habits in communities are linked and are part of the global food supply chain. To achieve sustainable food production and consumption, communicating the impact associated with food production and dietary choices at community level to consumers is important. However, previous footprint studies have primarily focussed on food consumption at the national level and neglected community–level consumption activities. This study surveyed the diets of a small island community and linked the results with multi-region land footprint analysis in Ollei Village, Republic of Palau. The analysis was used to determine the extent to which the dietary lifestyles of communities depend on external land use through the global supply chain. We showed that the global food supply chain has reached this corner of the world, and the dietary habits of the community are already heavily dependent on processed and imported foods. The community and country are highly dependent on large land use in some major producer/exporting countries through the global food supply chain. In addition, the amount of external land used for food production exceeds the biocapacity of the agricultural land in the community and country. This study bridges the gap between community–level consumption activities and national-scale footprint analysis, and quantitatively assesses the impact of consumption activities at the community level on the global environment. The results and approach of this study could contribute to the development and implementation of vertically integrated food policies between the national and community level in Palau.

In Japan, the world’s most rapidly aging country, urban farming is attracting attention as an infrastructure for health activities. In Tokyo, urban residents generally participate in two types of farming programs: allotments and experience farms. The availability of regular interaction among participants distinguishes these two programs. We quantitatively examined the difference in changes in self-reported health status between participants in these two types of urban farming. We obtained retrospective cross-sectional data from questionnaire surveys of 783 urban farming participants and 1254 nonparticipants and analyzed the data using ordinal logistic regressions. As a result, compared with nonparticipants, participants in both types of urban farming reported significantly improved self-rated health (SRH) and mental health (MH). After controlling for changes in their physical activity (PA), although participants in allotments did not report significant improvement in SRH and MH, those in experience farms did, suggesting that their health improvement was not only caused by an increase in PA but also by social interaction among participants. From the perspective of health promotion, public support is needed not only for the municipality’s allotments but also for the experience farms operated by the farmers themselves.

<p>The study historically identifies how Oya-stone quarrying has been affecting the local use of Oya-stone by taking residential areas in Utsunomiya City as case study sites. Topographical maps and historical literatures were examined while interviews and field observations were conducted to identify historical changes of the industry and the use of Oya-stone. The study identifies that stone walls remaining in old districts are mainly made of Oya-stone with a rough texture quarried by hand, while relatively low quality rough-textured stones quarried by machines are mainly used for foundations in new town districts. These findings illustrate that the buildings and infrastructures of Oya-stone has been characterized by the way how the stones were quarried and used. It is therefore suggested that measures to conserve local buildings and infrastructures should reflect how local materials were used in response to the industries.</p>

In Japan, illegal cultivation practiced on riverbeds is often perceived negatively by the public. However, guerrilla gardening, a similar phenomenon of illegal cultivation, is positively recognized in other parts of the world including Europe and North America. By using the term “Katte-Kosaku (勝手耕作)” to conduct an unbiased analysis, this study aims to identify welfare functions of Katte-Kosaku through a case study in Chiba City. The results show that Katte-Kosaku provided support to socially vulnerable people, and the act of Katte-Kosaku was accepted by some people surrounding it. Ultimately, this paper reveals that more research is required to further advance the discourse on whether Katte-Kosaku can be positively recognized by Japanese society.

The 2020 Olympic Games marathon will be run through the streets of Tokyo on the mornings of August 2nd and 9th, a time of year that is typically hot, sunny, and humid. Few studies have assessed the potential impact of extreme heat along the marathon course to understand the multiple factors (e.g., radiation, wind flow) affecting human thermal comfort (TC) as influenced by urban design and vegetation. The current research establishes a baseline of microclimate conditions and scenarios to estimate the projected TC along the marathon route for spectators. Mobile microclimate data (air and surface temperatures, solar radiation, humidity, wind speed) were collected along the marathon course over 15 periods in the summer of 2016 and aligned with sky view factors (SVF). Human energy budget modeling was applied to provide spatially-explicit heat budget and TC information along the route. Conditions are expected to create the most discomfort along open, sun-exposed locations, with ~50% of the area along the second half of the course resulting in 'Hot' (budget > 200 W m-2) or 'Very hot' (budget > 295 W m-2) conditions. The heat strain index frequently rises above 80% in these locations, with high humidity and low wind flow exacerbating discomfort. Buildings and trees producing a low SVF over roads and sidewalks protect spectators from the morning radiant heat, but such locations should be balanced with wind flow to optimize comfort. The modeling and spatial information can aid in preparing for and mitigating heat stress during the Olympics. Potential solutions can be implemented in collaboration with local organizers and government. This 'research through design' strategy can aid in preparing for and mitigating heat illness during the Olympics. Knowledge gained can be extended to other areas of Tokyo to reduce urban heat, and further provide targeted guidance for effective environmental cooling techniques for human health.

By conducting a questionnaire survey in Hachioji City, Tokyo, this research has analyzed the maintaining/leasing intentions of Productive Green Land owners and its influencing factors. Results showed that other than individual factors previously reported, some locational factors were independently related to Specific Productive Green Land designation intentions. With the results showing farmland owners' intentions on PGL leasing, we have discussed on preservation methods of urban farmlands in the contemporary context of shrinking suburbs. We have understood that farmlands in areas with low land prices and low ratio of agricultural land are the most vulnerable though in need most of preservation, and leasing the land to new entrants into farming is a relatively possible solution in preserving and maintaining farmlands in those areas.

In response to the phenomenon of urban shrinkage that affects many Japanese cities, and its various associated social issues, the Japanese Government has implemented compact city policies as a part of urban planning. A compact city is characterized in Japan by dense and proximate urban areas that are linked by public transformation systems, but the feasibility of applying a single compact city model to different regional or local circumstances is susceptible. To understand the actual state of urban shrinkage, this study was aimed at examining spatial emerging patterns of vacant land in residential areas of mid-sized cities called “regional urban centers” in Japan where such patterns are still unknown. The study was conducted using a three-step procedure: a) identifying the overall trends of urban shrinkage in all Japanese regional urban centers and selecting a case study site b) constructing a detailed database of vacant land and five characteristics of the residential areas: age, orderliness, distance from the central area, convenience of public buses, and road width, and c) identifying the relations between the number of vacant lands and the characteristics of the residential areas by using a Poisson regression model. Tottori City, a regional urban center of Chugoku Region, was selected as the case study site. The results show that the convenience of public buses, one of the emphasized factors when the government made a compact city plan, had no relationship with the distribution of vacant land. It might be because Tottori residents highly depend on private cars and are little concerned with public transportations. Instead, a narrow road width appears to be one of the crucial hindrances of residential replacement. A high rate of vacant land then should be regarded not as problematic space but as a resource for reconstruction of residential areas, such as the widening of narrow roads.

The purpose of this study is to identify influences of urban farming on the health of older persons by focusing on the differences of individual farming or group farming. Farms practicing group farming and individual farming in the suburb of Yokohama city were selected as case studies, and a questionnaire survey and interviews were conducted at the farms. The study identified that; (1) More than 80% of the older persons responded that they were maintaining or improving their health condition. (2) Urban farming has more positive effects on maintaining older persons' health condition than other social activities. (3) Group farming is more effective than individual farming for the improvement of mental health and social health. Integration of group farming and individual farming is perceived to be the most effective measure to maintain older persons ' health condition.

<p>The study aims to identify the impacts of population decline on the nightscape of Nagasaki City, which has been acknowledged by tourists as one of three major nightscapes in Japan. In particular, the focus was given to hillside residential areas, which frame the landscape of Nagasaki. The study was conducted by following three steps procedure as a) visualizing the present nightscape by using ArcMap and ArcScene, b) developing scenarios on future population decline, and c) visualizing future nightscapes based on the scenarios. The scenarios developed are based on two hypotheses on the future population of Nagasaki as the decline will occur; 1) equally throughout the entire city, and 2) exclusively at the hillside residential areas because of their inconvenience especially for elderly people. The study identifies that the nightscape following the scenario 1 will become deteriorated compared to the present but still may maintain its character, while the scenario 2 will lead the nightscape to lose its identity. It is therefore concluded that taking measures to suppress depopulation of the hillside residential areas are indispensable to maintain the identity of Nagasaki's nightscape.</p>

The study aims to identify the relationship between willingness to pay for environmental protection and tourist satisfaction. The Republic of Palau is selected as a case study, where the national government collects the environmental protection fee of US dollar 30 from all the tourists and the state governments collect the entrance fee of US dollar 10-100 from the tourists who enter protected areas. A questionnaire survey was conducted on Japanese tourists. The study identified that more than 90% of the tourists had affirmative opinions on the payment and wanted to revisit even if they pay around US dollar 50-150. However, more than half of the tourists couldn’t satisfy their payments, as they couldn’t realize their contribution to the environmental protection and/or local society. The satisfaction level of the tourists who leaned the payment system by themselves through magazines or websites was higher than those of the others who were instructed by tour guides or who were not informed by anybody. These results indicate that if the governments improve the transparency of their use of money and notify the tourists of positive effects on local society and/or environmental protection, more tourists could realize their contribution and recognize their responsibility as beneficiaries.

The impacts of climate and socioeconomic change in the future are important factors to consider when discussing sustainable development in the Pacific Islands. The tourism industry serves as the key driving force behind economic growth in island regions, largely promoted by their environmental attractions. In this study, the relationship between historical land use changes and sediment yield in Babeldaob Island, Palau, was estimated using the Soil and Water Assessment Tool (SWAT) and assessed in terms of the sufficiency of land resource use. The results showed that the annual sediment yield during three different periods—self-sufficient (1921), resource development (1947), and environmental conservation (2006)—were 2.6 ton ha⁻¹ yr⁻¹, 8.1 ton ha⁻¹ yr⁻¹, and 5.8 ton ha⁻¹ yr⁻¹, respectively. Additionally, annual sediment yield per capita (SRc), an indicator of land resource use sufficiency, consistently declined across these periods, measuring 0.41 ton capita⁻¹ ha⁻¹ yr⁻¹ in 1921, 0.30 ton capita⁻¹ ha⁻¹ yr⁻¹ in 1947, and 0.29 ton capita⁻¹ ha⁻¹ yr⁻¹ in 2006. Furthermore, when considering land resource use by tourists, SRc further declined to 0.27 ton capita⁻¹ ha⁻¹ yr⁻¹, quantitatively demonstrating that the promotion of tourism reduced dependence on local resources and alleviated environmental burdens.

Tokyo metropolitan area has experienced torrential rains frequently, which were causing serious inundation floods. This paper evaluates rainwater infiltration and flood prevention effects by urban green spaces using a combined inundation simulation model. The study site is the Kanda River, Tokyo. It simulates three cases: present green space, green space decrease scenario and green space creation scenario. As a result, the infiltration amount decreases 0.8 times and the inundation area increase 1.2 times by the application of the decrease scenario, which reduce private green spaces by half. The infiltration amount increases 1.3 times and the inundation area decrease 0.7 times by the application of the creation scenario, which increase both public and private green spaces. It is found that the urban green spaces have significance effects on the rainwater infiltration and flood prevention. In particular, not only the public green spaces, but the private green spaces have important role.

The purpose of this research is to identify the history of natural conservation related to tourism development in the Republic of Palau through literature review and interview survey and to investigate the effectiveness of the current natural conservation polices at two case study sites. The results show that the primitive natural conservation had focused on sustainable use of natural resources by local communities, and it has then turned into wildlife conservation because of the many environmental issues, for example, the severe coral bleaching event, the soil erosion problem caused by new developments, and the environmental degradation by tourist activities. Currently, the unique natural conservation policies are in effect such as Protected Area Network, Micronesia Challenge Endowment Fund, and Green Fee. The national government carries out those policies by means of attracting tourists, who pay the Green Fee, and gathering attention from international society, which donates Micronesia Challenge Endowment Fund. The national government distributes those funds to local communities, which manage their natural resources sustainably as the Protected Area Network sites. The funds are used not only for the conservation objective itself, but also for the purpose of the small community developments such as starting nature tourism projects. The result of this study would be useful for discussing the direction of nature tourism development in Japan.

The Republic of Palau has a unique culture of medicinal herbs use. In particular, in the first birth ceremony, they care mother's body with various kinds of herbs and celebrate the first birth with family and community. This study clarifies the kinds of medicinal herbs for the ceremony and determines important landscape elements for collecting the medicinal herbs by a behavior survey using a GPS in a village. The following points are clarified. In the ceremony, 24 kinds of herbs were used. Among those, 11 herbs were collected in the agroforestry inside of the village and 13 herbs were from the surrounding environments such as grasslands and limestone forests. Given the recent conversion of grasslands to urban settlements, it is essential to conserve various landscape elements in total as well as preserve the knowledge of herbs in order to inherit the cultural activities. The behavior survey using the GPS would be an effective method to show the places visually, which has important cultural meaning like the medicinal herbs use in the ritual.

The purpose of this study is to clarify the past and present conditions of the plantations and the bauxite mining landson the Babeldaob Island, the Republic of Palau, where was the Japanese colony before the WWII. In 1940, 1,671people lived in the four plantation villages of 2,236 ha. They cultivated mainly pineapples and cassavas and sold themto Japan; however deforestation and overharvesting by Japanese have still influenced the current vegetation and aninvasive spice Falcataria moluccana introduced by Japanese has affected the native species. Besides, there were twobauxite mining sites of 106 ha that were the biggest industry of the island. Although the areas were not large, thesedimentation from the mining sites was large amount and it affected not only the terrestrial and coastal environment,but also Palauan villages, too. Since both development sites were located along the water system, influences on thenatural and social environment were spread over the watershed long time.

This study aims to clarify the relations between trees-and plants-use and the ritual space structure in the tropical agroforestry. We gathered some information on traditional ceremony related to first-birth and death, recorded all plants species in certain plats around ritual spaces, and drew down the space structure. As a result, we found that kitchen garden around the house works as a place for both first-birth and funeral events and that a lot of trees and plants for the rituals can be intensively seen around the stone platform. That means Palauan agroforestry have a multi-function including cultural and spiritual meanings. However, the places where these ritual events are held have been changing from time to time. Though the first-birth ceremony is still held near houses, burial place is now chosen from various alternatives, such as tomb near the house, in the forest or public cemetery on hill top. Space structure also differs from place to place. That implies that traditional space structure -united relationship among daily-life, new born, and death ceremony- has collapsed.

This paper aims to clarify the cultural landscape of the traditional village of the Babeldaob Island in Micronesia. Airai village is chosen as a case site. The following three points were clarified. First, agroforestry such as Mekesokes, Chereomel, Mesei, and Sers are the main elements of cultural landscape of the village, which co-exist with the historical assets like old stone-paved road and traditional meetinghouse. Second, the agroforestry landscape has been maintained through the cultivation activities of horticulture, agriculture and arboriculture, and people also utilize the natural resources of the surrounding environments through plants collection, fishery and hunting. Third, the cultural landscape of the villages is the aggregation of the minute landscape units classified by land use based on micro-geography and human's livelihood. It seems that to identify the landscape units are the fundamental way for cultural landscape management or environmental management.

The purpose of this study is to clear the land use characteristics based on watershed analysis and deliberate historical methods of sustainable land use in Babeldaob Island in the Republic of Palau. The following three points were clarified. 1) From the perspective of 'change', comparing the location and number of villages between 1920's and 2006, thirty seven villages are still existing, twenty eight villages were disappeared and eight villages are new. 2) From the perspective of 'structure', the village type, which locates in the valley along the river, also adjacent to mangrove is typical one. Besides, the small watershed composes the fundamental structure of village. 3) From the perspective of 'function', mosaic land use, corresponding with the differences of the geological formation, and hierarchical land use in agroforest for multi-functions are identified. Therefore formation of village along the ecosystem order from upper stream to coast, and horizontal and vertical diversity of land use of village could be considered as important factors of sustainability in the island.

The purpose of this paper is to analyze the cultural landscape of the foreigners promenade near the Yokohama colony area during the end of Edo Era and the Meiji era, using 298 pictures on the basis of Yokohama pictures and Yokohama post cards. The following three points were clarified. Firstly, ten types of the cultural landscape were classified. The most dominant cultural landscape taken by the above pictures were Cliff Landscape and Water Edge Landscape. Secondly, the most important factor to designate the landscape structure was the formation of the cliff. The geological features of the cliff gave various view points and scenery. Thirdly, the foreigners promenade was deliberately planned to enjoy these characteristics. It was the first parkway in Japan, after the modernization.

This study aims to develop a new approach to assess the impact of climate change on the small oceanic islands in the Pacific. We developed a new index &ldquo;RAKUEN&rdquo; to assess the sustainability in these regions. The RAKUEN index focuses on the relationship among tourism, local society and environment. It is important to project the change of RAKUEN index considering the climate change. Hence, we focused on the impact of climate change on tourism in this presentation. The result indicated that the strength of extreme events would be increased, whereas the probability of occurrence would be decreased. This change should result in increase of the number of clear days and it could contribute to improve the tourist satisfaction.
