Flood Risk Index (FRI) is the multi-criteria linked with the factors of vulnerability; exposure, susceptibility, and resilience. In order to establish local FRI, crucial local information have to be accumulated. However, under the limitation of land-use data, particular techniques were applied in this study. CA Markov model was used to analyze the past missing land-use data and, also forecast the future land-use of Pakpanang river basin under conditions of plan and without plan. The ratio changes of forest, agriculture, wetland and water, and urban areas were considered. Then, the result of LULC spatial-temporal changes was then applied to Hec-HMS and Hec-Ras , with Arc GIS extension of Hec-GeoHMS and Hec-GeoRas software, in order to evaluate the flood hydrographs and flood severity in three municipalities corresponding to 100-year return period rainfall. Afterward, the FRI of Pakpanang, Chianyai, and Hua-sai, which ranges from 0 to 1, were evaluated by using the modified FRI equations. It was found that sensitivity analysis in the area of forest on flood depth and inundation areas is incoherent. Nevertheless, without land-use planning, the changes in these three cities cause higher flood risk, where Chianyai is the riskiest as the FRIE is 0.58. Further consideration of FRIE and FRIP proportion that reveals the FRI deviation indicates that to reduce flood risk, Chianyai would need the most resources and highest effort comparison to Pakpanang and Hua-sai.

Abstract The article is a case study of land use planning in the surroundings of the eastern side of the runway of the former airport Rakowice-Czyżyny in Cracow. The area was chosen because it is an example reflecting the history of many urban spaces that are well connected externally, well equipped in infrastructure, and favourably located in the city. They are now the scene of an intense market game, which arrogates to itself the almost unlimited right to determine the land use. Therefore, a study was conducted to verify the knowledge in that field. The analysis was based, inter alia, on differentiated source materials (including historical ones), a survey of press materials (mostly local ones), interviews with residents, the field analysis carried out in the research area and data analysis (primary market of real estate). The chosen example allowed the authors to confirm the theorems on the growing threats to the spatial order in a situation of struggle between supporters of neoliberal urbanism and broadly defined new urbanism. The latter cannot exist without spatial planning but since1990 in Poland we have been able to observe a crisis in this area. It leads to chaotic, too concentrated development in urban areas. This demonstrates that while the criticism of the new urbanism is in some dimensions justified, it cannot be used to legalize voluntary land development. This possibility of social and political permission for arbitrariness generates an “appetite” for space understood primarily as an economic good.

Use Pattern

Land use mix (LUM) has long been employed as one of the key methods to improve urban vibrancy and optimize built-up areas. Within the urban studies discipline, LUM is usually defined as a functional compatible but diverse land use pattern. However, its quantitative methodological approaches thereby heavily rely on the diversity of land use and fail to consider functional compatibility as another critical defining characteristic, providing only a partial picture of land use pattern. Thus, reviewing LUM’s concepts and definitions, this paper develops a new index to describe functional compatibility according to the spatial segregation measurements. To evaluate and provide empirical evidence of the proposed index, this paper selects the medium-sized city of Xiangtan as a case study. The findings demonstrate that Xiangtan exhibits a quite compatible land use pattern to a certain extent. In addition, particular clusters with relatively incompatible land use patterns are observed, which are closely linked to a special historical working unit, the ‘Danwei’ compounds, and a special rural planning authority, ‘Township-Village-Enterprise’, in China. Finally, an integrated evaluation is conducted based on the proposed index and Shannon entropy index, which can be regarded as a useful tool in future land use planning while contributing to shaping a sustainable form of urban development.

AbstractProviding appropriate and equal healthcare to the various classes of society is among the major issues in social welfare. The spatial distribution and locating of health service centres are significant in addressing the healthcare needs of citizens. This issue needs to be evaluated using quantitative and qualitative approaches throughout those cities with high populations and activity density levels. By taking Isfahan metropolitan area as the case study area, in this study, a combination of Network Analyst tool within Geographic Information System (GIS) and an Analytic Hierarchy Process (AHP) model was used to evaluate the catchment areas of the 26 existing hospitals within the study area. Thus, with effective data collection in the form of layers of information such as transportation network, population density, land use, etc. using (GIS), the authors categorised urban land in seven categories from poor to very good for the construction of hospitals. The result of analysis indicated that existing hospitals covered approximately 24% of active urban areas within a standard access time. The result can be used for policy making and healthcare planning.

Land Use Patterns

Land use planning plays a crucial role in creating a balance between the needs of society, physical development and the ecosystem. However, most often poor planning and displacement of land uses particularly in urban areas contribute to social ills such as drug abuse and criminal activities. This research explains the spatial relationship of drug abuse and other criminal activities on urban land use planning and their implications on the society at large. Spatial statistics was used to show patterns, trends and spatial relationships of crimes and land use planning. Data on crime incidents were obtained from the Royal Malaysia Police Department whilst cases of drug abuse were collected from the National Anti-Drug Agency (AADK). Analysis of the data together with digital land use maps produced by Arnpang Jaya Municipal Council, showed the distribution of crime incidents and drug abuse in the area. Findings of the study also indicated that, there was a strong relationship between petty crimes, drng abuse and land use patterns. These criminal activities tend to concentrate in residential and commercial areas of the study area.

The potential of property rate has been least tapped by decentralized governments in Ghana. This paper investigates the property rating system in Ghana through a case study of Offinso South Municipality (OSM). Questionnaires were used to gather empirical data from property owners in the municipality. The paper finds that there is inadequate property tax administration system and high public disdain for the property tax in OSM, with a significant association between compliance with the property tax and land use regulations in OSM. The paper suggests that the Offinso South Municipal Assembly (OSMA) should improve its land use planning system to facilitate voluntary compliance with the property tax. OSMA should also address accountability and transparency problems in the property tax system in order to increase public confidence in the tax regime. The OSMA should also improve on the property tax collection modes by computerising the billing and collection processes.
