ResumenLa lectura de la ciudad a través del tiempo permite mostrar una dinámica vinculada a los intereses vocacionales de usos de suelo; destacando el cambio generado en las vialidades principales. La investigación que se realiza sobre una vialidad primaria en un fraccionamiento, muestra el registro de los cambios experimentados en ese eje vial que originariamente fue producto de un proyecto urbano con uso generalizado habitacional, evidenciando ahora la incontrolable inercia provocada por el ímpetu comercial y de servicios coexistiendo con agonizantes viviendas esporádicas subsistentes en un paisaje lineal modificado, agregándose la conflictualidad vecinal entre la lucha por la permanencia del uso habitacional y el nuevo uso comercial. Como un referente de la creación de fraccionamientos similares, se trata de demostrar el imprevisible cambio de uso de suelo para fines comerciales, por lo que se concluye en la propuesta previsora de mezcla de usos, acorde a los actuales requerimientos urbanos.Palabras clave: Cambio de uso de suelo; corredor comercial; uso mixto; vialidad primaria; residentes. AbstractObserving the city over time allows present a dynamic linked to the vocational interests of land uses; highlighting the change generated along main roads. This research carried out on a primary road in a housing development, records the changes experienced in that road that originally was the product of an urban project with exclusively residential use, showing the uncontrollable inertia caused by the commercial activities momentum coexisting with dying sporadic dwellings subsisting in a modified linear landscape, adding a conflict between neighbours for the permanence of residential use and the new commercial uses. As a benchmark for the creation of similar developments, it demonstrates the unpredictable change in land use for commercial purposes, which is why it is proposed a mix of uses, according to current urban requirements.Key words: Land use Change; Commercial Corridors; Mixed use; Primary Roads, Residents.

Abstract—Land use plans in Iraqi cities are traditional and don’t seek to be sustainable and therefore could have negative impacts on the city from the environmental, economic, social and urban aspects. Consequently, the research aims to analyze the current and future of the land use for a set of Iraqi cities to reach the indicators of the gap between traditional and sustainable plans when planning for land uses.  The research conclusion is that most Iraqi cities are highly urban sprawl, both in reality and in the future expansion of the city. That is because it consumes a lot of agricultural land, cities with low population densities that are unsustainable, and most land uses are unsustainable focusing on reducing the agricultural and green lands in the city and increase residential uses (single type with very low density), and expand the areas of the streets that depend on the automated transportation more than sustainable transportation.  The research suggests that sustainable land uses in Iraqi cities should be as follows:   Residential use: vertical housing pattern 30 %, horizontal housing pattern 15 %.   Mixed use 12 %.   Green, open and recreational areas 22 %.   Sustainable transport 13 %.   Public, community and government services 8 %.

The Mexican Caribbean and its main cities have the highest population growth rate in Mexico. This work goal was to analyze the growth of the city of Chetumal and the geopedological characteristics in which it has been developed, to identify potential hazards and thereby improve development programs. The methodology consisted in the study of geopedological characteristics and the analysis of land use changes in the city over time. The main problems of Chetumal are floods and subsidence. Floods are more common in areas where Gleysols soils are found in low-lying areas. The subsidence is associated to Leptosols with a phreatic mantle at a shallow depth where the precipitations favors dissolution of rock. The extrapolation of the relationships between geopedological conditions and the area occupied by the city, allows us to suppose that areas which the current Urban Development Program proposes for future city expansion will develop the same problems of subsidence and flooding as the areas already built in sites with similar conditions.

AbstractIn a metropolis, people movements design intricate patterns that change on very short temporal scales. Population mobility obviously is not random, but driven by the land uses of the city. Such an urban ecosystem can interestingly be explored by integrating the spatial analysis of land uses (through ecological indicators commonly used to characterize natural environments) with the temporal analysis of human mobility (reconstructed from anonymized mobile phone data). Considering the city of Milan (Italy) as a case study, here we aimed to identify the complex relations occurring between the land-use composition of its neighborhoods and the spatio-temporal patterns of occupation made by citizens. We generated two spatially explicit networks, one static and the other temporal, based on the analysis of land uses and mobile phone data, respectively. The comparison between the results of community detection performed on both networks revealed that neighborhoods that are similar in terms of land-use composition are not necessarily characterized by analogous temporal fluctuations of human activities. In particular, the historical concentric urban structure of Milan is still under play. Our big data driven approach to characterize urban diversity provides outcomes that could be important (i) to better understand how and when urban spaces are actually used, and (ii) to allow policy makers improving strategic development plans that account for the needs of metropolis-like permanently changing cities.

Urban shrinkage has become a common pathway (not only) in post-socialist cities, which represents new challenges for traditionally growth-oriented spatial planning. Though in the post-socialist area, the situation is even worse due to prevailing weak planning culture and resulting uncoordinated development. The case of the city of Ostrava illustrates how the problem of (in)efficient infrastructure operation, and maintenance, in already fragmented urban structure is exacerbated by the growing size of urban area (through low-intensity land-use) in combination with declining size of population (due to high rate of outmigration). Shrinkage, however, is, on the intra-urban level, spatially differentiated. Population, paradoxically, most intensively declines in the least financially demanding land-uses and grows in the most expensive land-uses for public administration. As population and urban structure development prove to have strong inertia, this land-use development constitutes a great challenge for a city’s future sustainability. The main objective of the paper is to explore the nexus between change in population density patterns in relation to urban shrinkage, and sustainability of public finance.

Land use is the utilization and reordering of land cover for human comfort. This process disrupts the pristine state of the environment reducing the quality of environmental receptors like water, air, vegetation etc. Air pollution is introduced into the environment as a result of anthropogenic activities from commercial, industrial and residential areas. These activities are burning of fossil fuels for power generation, transport of goods and services, valorization of raw materials into finished products, bush burning, use of gas cookers, generators and electric stove etc. The introduction of pollutants into the planetary layer of the atmosphere has impacted negatively on the quality of the environment posing threat to humans and the survival of the ecosystem. In Lagos metropolis, commercial activities and high population densities have caused elevated levels of pollution in the city. This study aimed to investigate the spatial distribution of pollutant in Lagos metropolis with a view to revealing the marked spatial/temporal difference in pollutants levels over residential, commercial and industrial land uses. Commercial and industrial land uses revealed higher levels of pollutants than the residential areas. Pearson product moment correlation coefficients revealed strong positive relationship between land use and air quality in the city.

Using the City of Corvallis, Oregon, a small to medium sized American city, as a test-bed, this paper examines the City’s urban growth in relation to urban accessibility. This relationship is explored in an anatomic spatial-temporal fashion, taking account of: the number and size of developed land use parcels over time; urban accessibility from residential to non-residential land use areas; and the statistical relationships between urban form and urban accessibility. This investigation of land use is structured around use-classification and examined within a range of dimensional and demographic measurements over 5-year time periods from 1853 to 2014; concurrently, urban accessibility is measured by the least-cost path distance as calculated through the OD cost matrix analysis in GIS. The results indicate that the city grew spatially at different rates and its urban accessibility experienced both ups and downs over time. The city’s population growth corresponded closely with urban growth and its decreasing population density negatively impacted on the city’s urban accessibility to commerce, industry, and office for most time periods. Significantly, while the urban density increased steadily after 1950s concurrent with an increase in urban sprawl, in contrast to previous studies on the metropolitan condition, the urban density had no evident impact on urban accessibility in Corvallis. Instead, increasing the land-use mix was a more effective and feasible approach to reduce urban travel path distance and enhance accessibility than increasing population density or urban development density. Accordingly, this research provides evidence-based policy recommendations for planning sustainable urban mobility and urban form in small to medium-sized cities.

Changes in land use, which threaten ecosystems and habitats, have an impact on run-off and water quality on urban areas. Using a GIS program we have classified the land use of the Humphreys Brook watershed and quantified the changes that have occurred using landscape metrics. A rapid growth of the city emerges from our results. All land use types of urban nature have seen an increase in surface areas to the detriment of natural land uses. Moreover the landscape indices are showing signs of rectangularity, where humans have introduced straight edges, and other common processes of transformation to the landscape.

This paper outlines a method for assessing experts' evaluation of how municipal revenues and expenditures are allocated across land use categories. The method includes selection of experts, the nature of their interactions, and the process by which their diverse opinions may be meaningfully aggregated. This method is implemented for the City of Vancouver, using two distinct groups of experts. The results from these two groups' efforts are strikingly similar, suggesting that vacant and commercial land uses are net fiscal contributors, while residential and industrial uses do not on average contribute revenues that cover the cost of services rendered by the municipality.

This article develops an analytical framework to connect the theories of market and planning failures with the reasoning of incorporating land use and pricing policies for reducing driving and car dependence. A multilevel multinomial logit model (MML) is applied to estimate the effects of neighbourhood land use characteristics and price variables on travel mode choice of non-work trips and their interaction effects in the city of Austin, Texas. Results reveal that pricing policies are more efficient for reducing auto travel while land use policies appear better for adjusting non-auto travel. The practical significance of land use policies for reducing car dependence are more reflected in the modified effects of land use on pricing elasticities of driving probability. Pricing policies are more effective for reducing driving in neighbourhoods with a higher sidewalk density and a better accessibility to mixed-use activity centres. These findings validate the theoretical analysis and demonstrate the importance of coordinating land use and pricing policies together in the transportation planning practice.

Abstract The city of Lagos, Nigeria has undergone rapid increase in population due to economic and commercial activities. As a result of this, there has been a persistent change in Land use/Land cover (LULC) of the city and shoreline through the years. This observation necessitated the use of multi-temporal satellite data to characterize shoreline changes between 1984 and 2016. Therefore, the study attempts to determine the shoreline change during the study period and the coastal land use and land cover (LULC) of the study area. Satellite data was acquired andsubjected to some image processing techniques such as image enhancement, supervised classification, and shoreline extraction. The digital shoreline analysis system (DSAS) in ArcGIS environment was utilized to cast transects and calculate statistical parameters for the shoreline and spatial data used was Landsat TM, ETM and OLI for the years 1984, 1990, 2000, 2004 and 2016 respectively. The results indicate that LULC changes in builtup areas increases rapidly during the years (1984-2015) from 12.2 -36.2%, water bodies increased from (1984- 1990-2000) from 52%, 54%, 52% and reduces to 47.4% in the year 2015 while vegetation cover reduces drastically through the year range from 36%, 33%, 29%, 24% and 16%. A total of 1034 transects were generated with 100m spacing and the average rate of change was calculated for the 32 year period (1984-2016). The linear regression rate (LRR) shoreline result shows a mean of -0.59m/year where 73.1% of transect fall under erosion and 61.8% accretion respectively. The end point rate (EPR) and net shoreline movement (NSM) analysis revealed mean shoreline change of -0.57m/year and -18.1m/period respectively from 1984-2016. The EPR and NSM results both revealed that 231 transect or 22.3% experienced erosion, and 805 transect or 77.9% with accretion. It was observed that significant accretion rate recorded along most sections of the shorelines is attributed to beach nourishment activities.
