Provision of Allotment Gardens and Its Influencing Factors: A Case Study of Tokyo, Japan

Allotment gardens (AGs) are widely used in metropolitan areas around the world to offer agricultural opportunities to urban residents. However, there are not enough individual plots for residents to rent for urban gardening, and research on AGs from a city-wide perspective is ongoing. In addition, AGs have a long history in Tokyo, yet few international studies on the current situation of AGs have addressed Asian cities. Thus, this study intends to analyze the provision of AGs and its influencing factors in Tokyo. Using ArcGIS combined the 472-points dataset created by geo-coordinate mapping with urban GIS data to reveal spatial characteristics in four dimensions. Results demonstrate that most AGs are in the urbanization promotion area; most municipalities have AGs; AGs are concentrated within 20 to 30 km from the center of Tokyo; the AGs’ clusters are located at the municipal boundaries. We conducted multiple regressions to determine the influencing factors at the municipal level, with the provision that AGs are related to population density, land price, and the ratio of productive green space. The policy implication of this study is that policymakers need to consider the siting strategy of AGs based on spatial characteristics of AGs.

Quantitative estimation method for urban areas to develop compact cities in view of unprecedented population decline

In Japan, high economic growth after the war brought about disorderly urban sprawl. The government then enforced an “area division system,” which divided city planning areas into “urbanization promotion areas” (UPA) and “urbanization control areas” (UCA). This system maintains the existing UPA size almost unconditionally and, in addition, aims to incorporate parts of UCA into UPA by the size corresponding to new housing demands, which is based on an incremental of the future population prediction. Therefore, there was no need for an objective judgment criterion to verify that the total size of the expanded UPA was suitable for the population size; there are also no related previous studies. Nevertheless, this was not recognized as a major problem when local government finances were abundant due to population increase. However, in Japan, the arrival of an era of unprecedented population decline is certain; maintaining a huge number of urban facilities at the current UPA size could seriously damage local government finance. Shrinking UPAs are an urgent issue and it is time to seriously discuss the appropriate UPA size for the size of the population. In this study, we developed a quantitative estimation method of UPA size, commensurate with population size, through regression analysis of the relationship between population and UPA size. This estimation method is based on the strong correlation between population and UPA size, therefore it can be used as a judgment criterion for local governments to reach appropriate UPA sizes when considering compact cities.

Characteristics of policies based on Basic Law for Urban Agricultural Promotion formulated by local governments located in urbanization promotion area of Tokyo

This study aims to show the characteristics of the local plan’s policies based on Basic Law for Urban Agricultural Promotion formulated by local governments. The survey area is 310 local governments in 11 prefectures in three major Metropolitan areas. First, we investigated local governments that formulate the local plan and examined the reasons. Next, we analyzed the purpose of the formulated policies of 18 local governments in Tokyo. The main findings were as follows: Among 11 prefectures, Tokyo had a large number of local governments formulating the local plan. These local governments implemented various policies. In particular, the adopted policies were different between the cities and wards. One of the policies independently formulated by the local government was “Branding of agricultural products.” On the other hand, no local government adopted “Promotion of agricultural cooperation between rural and urban areas.”

A Study on Policies for the Conservation and Utilization of Agricultural Land in Green Master Plans

Agricultural land in urban areas has been increasingly valued in recent times. As a result, the 2017 amendment of the Urban Green Space Conservation Act clarified that agricultural land is an important component of green space in Green Master Plans (GMPs). The purpose of this study is to examine the current status of agricultural land in GMPs and propose the manner in which policies for the conservation and utilization of agricultural land should be positioned in GMPs. This study analyzed 101 GMPs established by large cities in Japan. The conclusions can be summarized as follows. Newer GMPs had positioned agricultural land more clearly, especially in chapters delineating their current status and programs. Further, the programs can be divided into five categories: conservation, utilization of agricultural land, promotion of agriculture, cooperation with urban development, and measures established in the 2017 amendment. It has been proposed that, especially in cities with higher ratio of agricultural land to urbanization promotion areas and without adequate urban park space per capita, GMPs should clarify targets based on more detailed analysis of the current status, as well as have programs utilizing agricultural land in cooperation with urban development.

Hydrological Analysis with Respect to Spatial Changes of Urban Growth in Bengaluru City using Geospatial Technology

Urban Water Management is the practice of managing freshwater, wastewater, and storm water as components of a basin-wide management plan. It builds on existing water supply and sanitation considerations within an urban settlement by incorporating urban water management within the scope of the entire river basin. The pervasive problems generated by urban development have prompted, in the present work, to study the spatial extent of urbanization in Bengaluru City and patterns of periodic changes in urban development (systematic/random) in order to develop future plans for (i) urbanization promotion areas, and (ii) urbanization control areas. Remote Sensing, using USGS (U.S. Geological Survey) Landsat8 maps, supervised classification of the Urban Sprawl has been done for during 1900 - 2010, specifically after 2000. This Work presents the following: (i) Impact of Land use/cover on ground water level using well location data and (ii) Morphometric analysis of Bengaluru City. The outcome of the study shows drastic growth results in urbanization and depletion of ground water levels in the area that has been discussed briefly. Other relative outcomes like declining trend of rainfall and rise of sand mining in local vicinity has been also discussed. Research on this kind of work will (i) improve water supply and consumption efficiency (ii) Upgrade drinking water quality and wastewater treatment (iii) Increase economic efficiency of services to sustain operations and investments for water, wastewater, and storm water management, and (iv) engage communities to reflect their needs and knowledge for water management.

Public–private collaboration in allotment garden operation has the potential to provide ecosystem services to urban dwellers more efficiently

There has been a growing global interest in urban agriculture that contributes to the well-being of urban dwellers by providing various ecosystem services. Focusing on allotment gardens, this study quantitatively analyzed their economic conditions, ecosystem service provisions, economic and environmental efficiencies, and the differences among them as regards their location and management. A questionnaire survey was used for data collection as a basic input for the quantification of economic conditions and ecosystem services of 223 allotments in Saitama Prefecture, Japan. Data envelopment analysis (DEA) was used for analyzing the economic and environmental efficiency of each allotment. Statistical analyses were conducted to explore statistically significant differences in economic conditions, ecosystem service provisions, and economic and environmental efficiencies among the four groups of allotment gardens classified by location (i.e., urbanization promotion area [UPA] and urbanization control area [UCA]) and type of actor (i.e., public or private). Our analysis identified that the expenditures of public allotments tended to be significantly larger than those of private allotments, whereas there was no difference in the income among the four groups, which resulted in lower economic efficiency of public allotments. Moreover, although public allotments in UCA and UPA provided a large amount of food production, recreation, and disaster prevention services, DEA revealed that they were less environmentally efficient when expenditures such as land rent, construction cost, and operational cost were considered. Our findings also identified that public allotments provided a significantly large amount of ecosystem services for urban dwellers in exchange of large public expenditures, which often resulted in inefficient allotment operation. If local governments and private actors build a collaborative relationship and strategically divide their roles, the governments could decrease the financial burden in the establishment and operations of allotments while maintaining/increasing benefits arising from allotment gardens.

A Study on Automobile Low Dependency Area outside the Urbanization Promotion Areas.

都市のコンパクト化を進めていくことに伴って，都市機能の縮退が進むことが予想されるエリア（縮退エリア）における交通利便性の低下や，自動車への過度の依存が懸念される．また，土地利用に余裕が生じると考えられる縮退エリアを特定の分野で活用する動きも見られる．そこで，縮退エリアへの良好なアクセスを確保することを目的として，市街化区域外を縮退エリアとみなして交通の実態を把握した上で，自動車分担率の低い地区を交通手段構成比に着目して分類し，分類した類型間の比較を行う．その結果，縮退エリアの交通整備の参考となるような自動車分担率の低い地区は代表交通手段構成比別に4つの類型に分けられ，縮退エリアの交通整備の方法が複数存在する可能性が示された．

Building Reconstruction After Large-Scale Disasters A Case Study of Ishinomaki City After the Great East Japan Earthquake

In large-scale disasters and the subsequent recovery process, land usage and urban spatial forms change. It is therefore important to use this process as an opportunity to create a more sustainable spatial structure. This study considers the urban spatial transformations that took place after the Great East Japan Earthquake, their causes, and accompanying issues by investigating building construction in the recovery process. The authors discovered that individual rebuilding is primarily concentrated in vacant lots within the city’s existing urbanized areas. This is likely due to the spatial impact of the urban planning and agricultural land use planning system, the area division of urbanization promotion areas, and the urbanization restricted areas, all of which were in place prior to the disaster and which have guided development. On the other hand, there are areas severely damaged by tsunami in which there has been little reconstruction of housing that was completely destroyed. The authors concluded that building reconstruction in Ishinomaki City resulted in both the formation of a high-density compact city and also very low-density urban areas.

Land Use Change after Large Scale Disasters a Case Study of Urban Area of Ishinomaki City after the Great East Japan Earthquake

The recovery process from the large-scale disaster causes the diversion of land use on a large scale. It is, therefore, important to consider whether or not these changes are connected to sustainable spatial forms. This paper aims to clarify the post-Great East Japan Earthquake urban spatial transformations by investigating the diversion of agricultural land in the recovery process. The authors found that in the urban area of Ishinomaki city, land use diversion from agricultural use to urban-type was carried out mainly either in urbanization promotion areas or in urbanization restricted area collectively and orderly adjacent to UPAs. The former especially contribute to the formation of high-densely efficient urban land use. They also concluded the disorganized expansion of the urban area caused by relocation of the affected people was suppressed thanks to the both urban and agricultural land use regulation i.e. land development and land diversion regulation in URAs, established before the disaster.
