Urban sprawl is a challenge of the century across the globe; however its greatest impact is felt more in developing countries mainly due to its poor planning and ever increasing population. To ascertain how this affects a notable African city, Abuja, a questionnaire design was employed to elicit resident’s perception on the causes and effects of sprawl in the city. A principal component analysis was performed to simplify the relationship between large bodies of variables involved. This was able to collapse the 14 variables representing the causes of sprawl extracted from the response of the respondents and 9 variables representing the effects of sprawl on the environment and on the residents into significant and orthogonal components that explained the variables in the observed data. Among the nine factors that loaded highly on the components, population was the major factor discovered to be responsible for the sprawl. The analysis further showed the main effects of the sprawl on the city as: loss of biodiversity, high dependency on car, traffic congestion, land degradation, alteration of microclimate, destruction of aesthetics, increasing crime wave, pollution and waste management problems. Adhering to the guidelines on urban development for the city will help the residents not to be prone to the effects of urban sprawl and help to maintain good environmental standards and less spending on maintenance on the part of the government.

RESUMOOs desastres relacionados às águas, ocorridos no Brasil, aprofundaram e ampliaram as pesquisas sobre tais fenômenos. Este artigo analisa os conflitos decorrentes da resposta do governo da cidade de Campos dos Goytacazes/RJ às consequências dos desastres: o programa de habitação popular “Morar Feliz”. Realizaram-se levantamentos bibliográficos, coleta de dados em órgãos públicos e entrevistas com moradores reassentados. Os resultados indicam a existência de conflito de interesses que opõem os moradores que reivindicam ficar no bairro em que residem, ou próximo a ele, e o governo municipal, que promove a expansão urbana em áreas com insuficiência de infraestrutura urbana.Palavras-Chave: desastres ambientais, habitação popular, risco.RESUMENLos desastres relacionados con el agua que ocurrieron en Brasil profundizaron y ampliaron las investigaciones sobre estos fenómenos.

Analysis of urban sprawl is an issue that has been continuously attracting attention in the planning and research community. This paper presents the results of an analysis of the growth of the city of Madurai. Madurai is a city in the south part of Tamilnadu, commonly referred to as Temple City with many historical cultural places being safeguarded. The population of Madurai has grown tremendously and hence the need for more build up area has increased during the past 12 years. In our study, we analyze the development of urbanization in terms of Landuse, Landcover between 2007 and 2019 using GLR and PMR values. The growth of population is directly proportional to the value of the land which is evident by the growth in GLR and PMR values. GLR is the guideline value from the government sector for a land while PMR is the privilege market rate for the same land.

<p class="Abstrak">Banjir merupakan masalah yang terjadi hampir diseluruh kota di Indonesia, tak terkecuali di kota Palembang. Masalah banjir di kota Palembang sudah menjadi masalah yang serius bagi pemerintah kota Palembang. Banjir di kota Palembang terjadi akibat banjir pasang musiman maupun banjir genangan akibat hujan yang sering terjadi di jalanan. Banjir yang terjadi di jalanan, dapat menyebabkan kerusakan terutama kendaraan baik roda dua maupun roda empat. Selain itu banjir juga dapat menyebabkan kemacetan lalu lintas karena kendaraan harus memperlambat kendaraannya agar tidak merusak kendaraan serta tidak menggangu pengendara lain yang melintas. Permasalahan utama dalam penelitian ini adalah tidak adanya aplikasi untuk mengetahui daerah atau jalan mana saja yang berpotensi terjadinya banjir khususnya di kota Palembang. Oleh sebab itu dibutuhkanlah suatu aplikasi dengan memanfaatkan teknologi komunikasi <em>mobile</em> yang dapat memberikan informasi kepada masyarakat, terutama pengguna kendaraan yang sedang berada di jalan agar dapat terhidar dari bencana banjir. Dengan memanfaatkan layanan titik lokasi menggunakan <em>Google Maps</em> dan API, penulis akan membangun sebuah aplikasi berbasis android, yang bertujuan agar dapat memberikan informasi pengguna kendaraan tentang lokasi titik rawan banjir saat terjadi hujan maupun banjir musiman di jalan-jalan kota Palembang, sehingga dapat membantu pengendara menghidari kerusakan kendaraan akibat banjir serta dapat membantu mengurangi kemacetan pada saat terjadinya banjir agar dapat menghemat waktu perjalanan.</p><p class="Abstrak"> </p><p><strong><em>Abstract</em></strong></p><p><em>Flooding is a problem that happens almost throughout the city in Indonesia, no exception in Palembang city. The problem of flooding in the Palembang city has become a serious problem for the Government. Flooding in Palembang occur due to tidal flooding or flood inundation due to seasonal rains that often occur in the streets. The flooding that occurred on the streets, can cause damage especially two-wheel vehicles or four wheel. In addition to flooding can also cause traffic congestion because the vehicles had to slow down their vehicles so as not to damage the vehicle and does not interfere with other riders crossing. The main problem in this research is the lack of application to know which road areas or potential occurrence of flooding especially in Palembang. Therefore it needs an application by making use of mobile communication technology that can provide information to the public, especially users vehicles that are on the way so it can be terhidar from the flood. By utilizing the service point location using Google Maps and API, the author will build an android-based applications, the aim is to be able to provide information about the location of the point of vehicle users prone to flooding in the event of rain or flood seasonal in the streets of the city of Palembang, so you can help motorists avoid vehicle damage due to flooding and can help reduce congestion at the time of the occurrence of flooding in order to save on travel time.</em></p><p class="Judul2"> </p>

Introduction: Rio de Janeiro is the second-largest city in Brazil, with strong socio-spatial segregation, and diverse and heterogeneous land use, occupation, and landscapes. The complexity of dengue requires the construction of surveillance and control tools that take into account the historical, social, economic, and environmental processes mediated in the territory as a central axis of public policy. In this context, this study aimed to stratify the city into areas of receptivity to dengue, using innovative “territorial indicators” because they are built based on the actual occupation of the territory. Methods: We designed and constructed 17 indicators that sought to characterize the transformed and inhabited space according to receptivity to dengue. We used data on land use and occupation, connectivity, climate, and landscape. We developed the dengue receptivity through principal component analysis (PCA), using multiple criteria analysis and map algebra integrated in a GIS platform. Results: The most receptive areas were concentrated in the transition between the north and west zones of the city, a region of unconsolidated urban sprawl. The areas of greatest receptivity had the highest incidence and density of Aedes eggs during the study period. The correlation between receptivity index and incidence rate was positive in the epidemic years. Conclusion: The proposed set of indicators was able to identify areas of greater receptivity, such as regions of disorderly urban sprawl, with a concentration of social and environmental processes that are related to the occurrence of dengue outbreaks and high vector density. On the other hand, population immunity plays an important role in the spatial distribution of dengue during non-epidemic years.

Os mapas históricos preservam informações geográficas sobre a ocupação humana, a expansão urbana e as transformações ambientais ao longo da história. Nesta perspectiva, efetuamos a coleta, catalogação, descrição e interpretação de mapas do sítio urbano da cidade do Rio Grande, a fim de investigar a expansão urbana desde a fundação em 1737 até 2017. No presente estudo foram analisados oito produtos cartográficos representativos da expansão do núcleo central urbano da cidade do Rio Grande, foi utilizado desde documentos cartográficos históricos do século XVIII até as imagens de satélite da atualidade, buscando identificar a área urbana e suas transformações. As análises mostraram uma expansão urbana em função do crescimento demográfico propiciado pelas atividades militar, portuárias e industriais, que provocaram   profundas alterações na geomorfologia original do pontal. Adicionalmente, a condição fisiográfica é um dos maiores desafios para a expansão urbana do Rio Grande, novas porções de terrenos continuam sendo incorporados ao urbano através de aterros das áreas inundáveis por particulares, nas margens da Lagoa do Patos e Saco da Mangueira. E os projetos formalizados, oriundos do Poder Público, no passado promoveram as principais mudanças ambientais como, por exemplo, os aterros na área do porto, mas atualmente os projetos utilizam de áreas regularizadas. Favorecendo o adensamento urbano. A expansão urbana da cidade aconteceu em resposta à necessidade de desenvolvimento frente aos diversos ciclos econômicos de sua história, alterando a fisiografia do pontal arenoso para atender as demandas socioeconômicas de cada período.  Historical Cartography of the City of Rio Grande / RS: Urban Expansion between 1737 and 2017 A B S T R A C THistorical maps preserve geographic informations of human occupation, urban sprawling and environmental transformations throughout history. In view of this, was performed a map collection, cataloging, description and interpretation of the urban site of the city of Rio Grande, in order to investigate urban sprawling and environmental transformations since its foundation in 1737 to 2017. In this study, eight cartographic products were analyzed, representative of the Urban Core sprawl in Rio Grande, used from historical cartographic documents of the eighteenth century to the satellite images of today, attempt to identify the urban area and its transformations. The analyzes showed an urban expansion due to the demographic growth provided by military, port and industrial activities, which caused profound changes in the original geomorphology of the cape. In addition, the physiographic condition is one of the major challenges for the urban expansion of Rio Grande, new portions of land continue to be incorporated into the urban through landfills of flooded areas by individuals, on the shores of Patos Lagoon and Saco da Mangueira. In contrast formalized projects from the government have, in the past, promoted greatest environmental modifications, such as landfills in the Port area, but currently, the projects use regularized areas which supports urban densification. The urban sprawl of the city occurred in response to the need for development in the face of the many economic cycles of its history, changing the sandy ape physiography to better serve the socioeconomic demands of each period.Keywords: Map, Historical Record, Urban Sprawl.

At present, traffic problem has become one of the biggest problems about the development of urban city in China. Faced with this problem, it is important for traffic planning to keep traffic be in accordance with the city. It is a challenge to urban planning, especially to the traditional method by land utilization planning. To relieve traffic congestion and other issues blocking, we can not only enhance road construction, but also make some innovation about the new thoughts and methods for the functional departments of the government. This is the key to solve the urban traffic problem for the time being.

Algerians citizens most often travel by foot on their daily trips because the lack of a homogeneous offer of public transit and intermodality throughout the city. Furthermore, the private vehicle is experiencing a notable increased use over the last few years. To curb this tendency, the government has launched a metro and a tramway system as key parts of a whole sustainable transport strategy. Guaranteeing the profitability of these modes of transport demands a high quality operation level focused on the users’ needs and requirements. While numerous studies have been carried out in developed countries for identifying the essential aspects of different transit modes, this area is still new in developing countries. Then, this paper aims to identify the key quality factors of the railway transit services in Algiers for advising transit authorities and managers towards the most appropriate policy measures. The railway transit services in Algiers consist on three modes of transport: the metro, the tramway (both started into operation in 2011), and a commuter rail system. A Principal Component Analysis combined with a regression model integrates the assessment approach. The results of this research highlight differences among the transit systems analyzed and provide useful insights for the Algiers government and transit authorities.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4100

The Special Capital Region of Jakarta (DKI Jakarta) is the country's capital and largest city in Indonesia. Jakarta as a large capital city has an attraction as a place to look for income, it is very attractive for residents from various regions in Indonesia to come to Jakarta who are settled and claim to be citizens of Jakarta. The number of migrants in Jakarta is around 68,500 people and it is predicted that as many as 60% live in Jakarta. Jakarta is a city with a fairly rapid economic growth rate. At present, more than 70% of state money is circulating in Jakarta. Since the early 1980s, the DKI Jakarta Government has been intensively building modern shopping centers, or commonly known as malls and plazas. At present Jakarta is one of the cities in Asia that has many shopping centers. In addition to luxury shopping centers, Jakarta also has many traditional markets and wholesale trade centers. For smaller environments, shopping centers for daily necessities are also available at affordable prices, such as Indomaret and Alfamart. The city of Jakarta as the capital of Indonesia focuses its development as the center of Indonesian business so that it is now densely filled with houses and tall buildings. The condition of the city of Jakarta is dense with residents and buildings, certainly there are many problems that arise, and the main problems of the city of Jakarta such as traffic jams, social problems and flooding. Traffic congestion makes Jakarta residents become lazy to leave the house so that an individualistic lifestyle makes social interaction decrease, also causes stress. The lives of Jakarta residents who live in high-rise buildings such as apartments that are mushrooming in Jakarta, which are very individual and cannot interact with the surrounding environment and daily activities are only "confined" in apartment units create a boring atmosphere and make residents become stressed. The problems faced by the City of Jakarta, of course, require solutions that really must be considered by the Government, especially the Local Government of the City of Jakarta. For that reason the author tries to make a city facility that can be a bridge between activities at home and work activities, in the social and economic fields in the form of Third Place, named Modern Hangout Market. Abstrak Daerah Khusus Ibukota Jakarta ( DKI Jakarta ) adalah ibu kota negara dan kota terbesar di Indonesia. Jakarta sebagai ibu kota yang besar memiliki daya tarik sebagai tempat untuk mencari penghasilan, sangat memikat penduduk dari berbagai daerah di Indonesia untuk datang ke Jakarta yang menetap dan mengaku sebagai warga Jakarta. Jumlah warga pendatang di Jakarta sekitar 68.500 orang dan diprediksi sebanyak 60% tinggal di Jakarta. Jakarta merupakan kota dengan tingkat pertumbuhan ekonomi yang cukup pesat. Saat ini, lebih dari 70% uang negara beredar di Jakarta. Sejak awal tahun 1980, Pemerintah DKI Jakarta gencar membangun pusat-pusat perbelanjaan modern, atau biasa yang dikenal dengan mall dan plaza. Saat ini Jakarta merupakan salah satu kota di Asia yang banyak memiliki pusat perbelanjaan. Di samping pusat-pusat perbelanjaan mewah, Jakarta juga memiliki banyak pasar-pasar tradisional dan pusat perdagangan grosir. Untuk lingkungan yang lebih kecil, tersedia pula pusat belanja kebutuhan sehari-hari dengan harga yang terjangkau, seperti Indomaret dan Alfamart. Kota Jakarta sebagai ibukota dari Indonesia memfokuskan perkembangannya sebagai pusat perbisnisan Indonesia sehingga kini telah padat dipenuhi hunian dan bangunan tinggi. Kondisi kota Jakarta yang padat dengan penduduk dan bangunan, pasti banyak permasalahan yang muncul, dan yang menjadi permasalahan utama kota Jakarta seperti kemacetan lalu lintas, permasalahan sosial dan banjir. Kemacetan lalu lintas membuat warga Jakarta menjadi malas untuk keluar rumah sehingga gaya hidup yang individualistik membuat menurunnya interaksi sosial, juga menjadi penyebab stress. Kehidupan warga Jakarta yang tinggal di gedung-gedung bertingkat tinggi seperti Apartemen yang menjamur di Jakarta, yang sangat individual dan tidak bisa berinteraksi dengan lingkungan sekitar dan aktifitas sehari-hari hanya “terkurung” dalam unit apartemen membuat suasana yang membosankan dan bikin penghuninya menjadi stress. Permasalahan yang dihadapi oleh Kota Jakarta, tentunya membutuhkan pemecahan yang benar-benar harus dipikirkan oleh Pemerintah, khususnya Pemerintah Daerah Kota Istimewa Jakarta. Untuk itu Penulis mencoba membuat suatu  fasilitas kota yang bisa sebagai jembatan penghubung antara kegiatan di rumah dan aktifitas kerja, dalam bidang sosial dan ekonomi berupa Third Place yang diberi nama Pasar Nongkrong Modern.

 KPPN Medan II is one of the government organization units at the Ministry of Finance. Where leaders and employees who work at KPPN Medan II always carry out official trips between cities and outside the city. With these conditions, making SPPD documents experiencing the intensity of official travel activities carried out by employees of KPPN Medan II can be said frequently. So that in making SPPD in KPPN Medan II is still using the manual method that is recording through Microsoft Word which in the sense is less effective and efficient. In naming employees who get official assignments, officers manually entering employee data that receives official travel letters are prone to being lost because data is manually written. The web-based SPPD application is built by applying this prototyping method which is expected to facilitate SPPD KPPN Medan II management officers in making SPPD that is effective, efficient, accurate, time-saving, and not prone to losing SPPD data of KPPN Medan II employees who will has made official trips due to the existence of a special database to accommodate all SPPD files.
