The increase in the growth of cities and the numbers of people moving to cities in the last two decades have led to sharp increase in transportation demand and development of slums and urban sprawl. Cities like Lagos, Ibadan, Kano, Port-Harcourt and Ilorin and other areas in Nigeria are experiencing many pressure on land use such as;, free-space, transportation facilities and a host of urban related problems which urgently deserve planners’ attention. Ilorin is one of the fastest growing cities in Nigeria. The problems of transportation and land use in Ilorin can be summarized into the following: long queue of people daily at ‘bus stops’, the problem of old narrow streets in most of the unplanned areas of the city and the emerging incursion of transport infrastructural facilities into the residential areas. To address these and other urban land-use problems world-wide, various governments have put in place different urban renewal programmes, but in the case of Nigeria little impacts on the city transportation and land-use systems had taken place. This research used exploratory method to justify the essence of planning in transportation system and on land-use in order to enhance and maintain sustainable development. The paper also suggests some measures like; expansion of existing narrow roads and provision of necessary infrastructural facilities, inter modality light rail/tram, creation of modern parks at specified locations as well as enlargement of public and private partnerships-involving the Government, transport associations, financial institutions, the available universities and some other professional bodies to serve as panacea to problems highlighted.

Models of digital elevation (DEMs), which provide elevation information for the ground surface of the catchment, are core components of computer-based analyzes for drainage basins. Many production methods are available, including contour interpolation, DGPS (Differential Global Positioning System) interpolation, and digital photogrammetry techniques. However, data on the precision and often contradictory nature of these three techniques are sparse. This study aims at identifying some of the contributing factors and comparing the accuracy of various approaches quantitatively. Changes in land coverage break ecosystem cycles, which may directly affect land ability to sustain human activity resulting in long-term trends of decline and inter-annual variability. It can be monitored at a spatial level of detail to enable the study of human-induced changes. Remote sensing techniques (RS) and geographical information system (GIS) methods have been used to extract the spatial and temporal changes of urban land use in the city of Al-Kut. The land sat satellite images taken in periods encompassing 1997, 2007, and 2017 are used. As a result, the city has lost a large part of its urban specificity and gained randomness and disorder in most of its residential neighborhoods, which was especially exacerbated after the change in the governing system in 2003. The results show an increase of 314% and 219% in industrial and residential areas, respectively, whereas agricultural land and open spaces have decreased by 66 % and 32%. The data analysis reveals a diagnostic relationship between land-use conversion and socio-economic drivers. This research sheds light on the total area changes of the Al-Kut city before and after 2003. It highlights the significant destruction of the city life, which was established over almost three centuries.

In this paper, a new frontal area index (FAI) mapping method is presented to describe the surface roughness of Renhuai, as an example of typical medium high mountain gorge type Karst city. Comparing with the traditional calculating method of FAI, a local topography (hills) factor is added to the calculation of the FAI in each 100 m × 100 m grid cell. The results show that the modified FAI is more strongly related to the mountainous land-use type than traditional, and local topography regions with large podium structure had higher values than other urban land-use types in mountainous city. With the frontal area index mapping procedure and a self-compiled least cost path analysis method, the potential airflow corridors traversing through the study area can be located, and the total computation time is shorter and less than 1 s. Air volume, a significant measurement index of urban ventilation capacity, is then simulated in computational fluid dynamics model (CFD-PHOENICS) to confirm the significance and efficiency of these specific ventilation corridors. Based on our findings, the government and urban planners may use the descendent maps to understand the urban ventilation paths within a mountainous city for urban local renovation decisions.

The paper presents findings of research about the classification of New Belgrade?s super-blocks using the typomorphology approach and the morphogenetic analysis of urban morphology in relation to land use. The example of New Belgrade is particularly interesting given the fact that the morphological patterns of land use within its superblocks were created during the period of non-market economy in Socialism, and now it is possible to review the effect that the socio-political transition into Capitalism, which started in the 1990s, has had on its land use. As a result, a data base with the typology of residential super-blocks of New Belgrade is created: from the perspective of urban land use there are four main morphological types (with the subtypes) taking into account the morphology of the position of the buildings on the terrain, and traffic (cars-pedestrian) flows. The morphogenetic analysis reveals that after the 1990s there are processes pointing to powerful influence of land policy driven by private interests. Research findings suggest that nowadays there are negative trends of using the land in super-blocks in New Belgrade - e.g. percentage of land occupancy by buildings is getting bigger and almost 100% of the un-built soil in the newly developed super-blocks is covered /paved.

Urban sprawl is a global phenomenon in the contemporary era. It is mostly taking place in the less developed countries due to natural increase and consistent movement of people into the mega cities and large urban centers. The phenomenon has globally gained attention from diverse researchers in the field of urban geography, environmental studies, city and region planning in view of its significant influence on the urban environment. However, the effect of sprawl on urban livability and economy in Nigerian cities is scarcely investigated especially in Northern Nigeria. This research explores the social and economic effects of urban sprawl in Kaduna metropolis. Remote Sensing and Geographic Information System (GIS) Technologies were applied for the analysis. The study found that Kaduna metropolis has experienced a progressive increase in the built-up area; in 2006 it had an aerial coverage of 13,980 hectares, a rise of 107.91% from 2001 aerial coverage of 6724 hectares. In 2012, the city had an aerial coverage of 15,808 hectares, an increase of 13.08% from 2006. Conversely, there has been a remarkable decrease in percentage of vegetation (1,458 hectares) and agricultural (11,739 hectares) land areas. In turn, such changes has adversely affected urban facilities or utilities such as pipe-borne water, electricity, health facilities, schools, security, transportation, wastewater infrastructures and fire safety services, which has become overstressed. Economic crisis has manifested in the rise of unemployment and escalating number of urban poor. Residential land use has encroached into open spaces while commercial activities overrun residential areas. Increase in distance and journey time make travel cost unbearable to the common man. These and social fragmentation retard livability in the city. Thus calls for a balance sustainable development in Kaduna metropolis and effective management of urban growth by the Kaduna Capital Development Board Authority. In due course, smart growth policy, growth management, urban containment, effective land use planning and public facility adequacy have been recommended to foster viable urban growth in Kaduna city and elsewhere.

Public And Private Partnerships

The article is devoted to the matters of public-and-private partnerships in the field of housing-and-communal services. The author recognizes, that sustainable urban development requires effective funding with the leading role of municipal finances. At the same time, financing of housing-and-communal sector through the municipal budget only would be too burdensome, while the use of the public-and-private partnership scheme has proved to be the good solution of this problem. However, there is no definite answer: whether the housing-and-communal sector is the most developed zone of public-and-private partnership or, on the contrary, it is an obscure and ineffective zone. The author analyzes the Russian experience of use of the public-and-private partnership scheme in the field of housing-and-communal services and reveals the main problems, which prevent the attraction of the private capital to this sphere. Such rather new trends as so called "box decisions" and "pool" securitization of infrastructure projects are considered in the article. According to the author, the use of these options could contribute to the development of housing-and-communal sector and the city infrastructure as well as the urban development as whole.

O processo de construção e aprovação do novo conjunto de leis relativas ao zoneamento de uso e ocupação do solo em Curitiba oferece elementos para uma análise dos conflitos de interesses que regem a constituição de um arcabouço legal e da luta simbólica que traduz na elaboração de um discurso que não se realiza nos termos da lei, mas que se cristaliza no imaginário dos citadinos. Tentando analisar esse processo e identificar dispositivos passíveis de serem generalizados como eficazes no controle de ocupação e uso do solo de outras cidades-modelo, na busca do protagonismo nos movimentos de inserção na reestruturação econômica internacional, este texto examina e sumariza observações quanto: ao apoio da lei no reforço à modelização urbana de Curitiba; à ausência de mecanismos e instrumentos que contemplem suas relações com o espaço metropolitano; aos efeitos socioambientais decorrentes da aplicação da lei; às questões referentes à constitucionalidade e à observação de princípios democráticos; às disposições referentes à ampliação da atratividade ao capital internacional; a sua abertura à participação da sociedade civil e à legitimidade de seus resultados. Urban land use regulation: discussion about the Curitiba’s case Abstract In 1999, a new land use law was approved in Curitiba. Its construction and approval process offers elements to discuss the meaning of a legal frame in the reinforcement of a hegemonic power around a metropolitan space, and the creation of conditions to attract the international capital, mainly from the real estate market. Trying to analyse this process, identifying elements possible to be generalised in the land use regulation of protagonists’ cities, this study examines and summarises observations on the topics: law for highlight the city-model; the lack of metropolitan instruments; conflicts between Instruments and particular interests; urban and social effects; constitutionality and observation of democratic principles. Finalising, the study intends to discuss that the dispositions included in the law and its illegitimate participation procedures have resulted in a refusing among society segments.

Land Use Maps

The utilization of urban land use maps can reveal the patterns of human behavior through the extraction of the socioeconomic and demographic characteristics of urban land use. Remote sensing that holds detailed and abundant information on spectral, textual, contextual, and spatial configurations is crucial to obtaining land use maps that reveal changes in the urban environment. However, social sensing is essential to revealing the socioeconomic and demographic characteristics of urban land use. This data mining approach is related to data cleaning/outlier removal and machine learning, and is used to achieve land use classification from remote and social sensing data. In bicycle and taxi density maps, the daytime destination and nighttime origin density reflects work-related land uses, including commercial and industrial areas. By contrast, the nighttime destination and daytime origin density pattern captures the pattern of residential areas. The accuracy assessment of land use classified maps shows that the integration of remote and social sensing, using the decision tree and random forest methods, yields accuracies of 83% and 86%, respectively. Thus, this approach facilitates an accurate urban land use classification. Urban land use identification can aid policy makers in linking human activities to the socioeconomic consequences of different urban land uses.

China’s urban land use has shifted from incremental expansion to inventory eradication. The traditional extensive management mode is difficult to maintain, and the fundamental solution is to improve land use efficiency. Xi’an, the largest central city in Western China, was selected as the research area. The super-efficiency data envelopment analysis (DEA) model and Malmquist index method were used to measure the land use efficiency of each district and county in the city from the micro perspective, and the spatial-temporal change characteristics and main influencing factors of land use efficiency were analyzed, which not only made up for the research content of urban land use efficiency in China’s underdeveloped areas, but also pointed out the emphasis and direction for the improvement of urban land use efficiency. The results showed that: (1) The land use efficiency of Xi’an reflected the land use intensive level of the underdeveloped areas in Western China, that is, the overall intensive level was not high, the gap between the urban internal land use efficiency was large, the land use efficiency of the old urban area and the mature built-up area was relatively high, and the land use efficiency of the emerging expansion area and the edge area was relatively low. (2) Like the eastern economically developed areas, the land use efficiency of western economically underdeveloped areas was generally on the rise, while Xi’an showed the U-shaped upward evolution characteristics, and there were four types of changes in the city, that is, highly intensive, medium intensive, high–medium–low-intensive, and intensive–extensive. (3) Various cities should configure resources and optimize mechanism to improve their land use efficiency based on economic and social development. During the study period, Xi’an showed the law of evolution from the south edge area and the emerging expansion area to the main urban area. (4) The improvement of technological progress was the main contribution factor of the land use efficiency in underdeveloped areas of China, and the low-scale efficiency was the main influence factor that caused low land use efficiency. In future urban land use, efforts should be made to optimize and upgrade technology and strictly control the extensive use of land.
