Na região Nordeste do Brasil existe uma gama de aglomerações urbanas, dentre as quais se destaca a conurbação urbana, conhecida como Crajubar, localizada na Região Metropolitana do Cariri (RMC), no sul do Ceará, onde existe uma percepção de ausência de limites urbanos entre os três municípios: Crato, Juazeiro do Norte e Barbalha. Assim, este trabalho busca compreender a dinâmica da expansão do Crajubar, por meio de técnicas de Geoprocessamento. Para tanto, utilizou-se arquivos vetoriais da delimitação territorial com mancha urbana do ano de 2005 e imagens orbitais dos satélites GeoEye do ano de 2018. Para o processamento dos dados foi utilizado o software QGIS. O Google Earth foi usado para identificar estabelecimentos responsáveis por atraírem crescimento urbano para o seu entorno, ainda foram utilizadas informações oficiais de crescimento populacional e informações econômicas geradas pelos órgãos oficiais. Como resultados, geraram-se arquivos vetoriais com duas manchas urbanas da região, sendo uma de 2005 e outra de 2018, as quais apresentam a conurbação dos três municípios para as duas situações. A partir do mapa gerado, construiu-se o entendimento dos fatores que impulsionam a expansão espacial urbana do Crajubar, tais como serviços públicos nas áreas de infraestrutura, saúde e educação. Evaluation of expansion of Crajubar urban agglomerate using geomatics A B S T R A C TIn the Northeast region of Brazil there is a range of urban agglomerations, among which the urban conurbation known as Crajubar. It is located in the metropolitan area of Cariri (MAC), in the south of Ceará, where there is a perception of the absence of urban boundaries between the three towns: Crato, Juazeiro do Norte and Barbalha. This work tries to understand the dynamics of the expansion of Crajubar, using Geoprocessing techniques. It was used shapefiles of the territorial delimitation with urban area of the year of 2005 and GeoEye satellites images of the year of 2018. The QGIS software was used for data processing. The Google Earth was used to identify companies and institutions responsible for attracting urban growth for the around their area, official information on population growth and economic information generated by government institutions was also used. As a result, shapefiles were generated with two urban areas in the region, one of area in 2005 and another area in 2018, where each one presents the conurbation of the three towns for both situations. From the generated map, the understanding of the factors that have influenced the urban spatial expansion of Crajubar was constructed, such as public services of infrastructure, health and education.Keywords: Urbanization, Population Growth, Geoprocessing.

Unbridled urban sprawl in Sub-Saharan African cities reflects an infirmity that warrants both vaccination and treatment to curb urban disorder and its costs. This article divulges that rapid population growth, spatial expansion and economic activities are responsible for the urban overspill and its upshot in Bafoussam. Unplanned settlement from the rapid growing population has led to the development of slumps and reduction of arable land. A multi-spectral Landsat satellite imagery of 1988, 2001 and 2016 was used to determine the spatial expansion of the town over a period of 30 years. Field observation and interview sessions were done to have information on the proliferation of economic activities to the expansion of the town. An in-depth secondary data collection was done to gather information on the rate of population growth of Bafoussam. The data was processed to generate maps through the ArcGIS 10.4 and Adobe Illustrator CS soft wares and tables through SPSS 17 for results and analyses. Results from findings propound a significant increase in the built-up area of Bafoussam of 19.34% in 1988, 50.30% in 2001 and 79.41% in 2016. This increase was accompanied by a drop in the vegetation of 78.64% in 1988, 48.50% in 2001 and 20.07% in 2016. The built-up increase was provoked by a persistent rise in the population of the city from 62, 239 inhabitants in 1976 to 112,681 in 1987 and 282,800 in 2010. Industrial and commercial activities developed in the course of the twin increase and unfortunately with no control triggered urban disorder. This article advocates for a mandatory implementation of the urban norms in Cameroon to liberate Bafoussam from the drowning overspill syndrome plaguing Sub-Saharan cities.

<p align="justify">Kecamatan Selat Nasik is one of the subdistricts in Belitung Regency with limited avaliability of clean water. It is because the district located in the archipelago with limited clean water sources. The purpose of this study is to determine the potential of clean water. The analysis of this study are: clean water analysis, population growth analysis, and water availability analysis. The final result shows availability of clean water both 466.366 liter per person per day (in 2018) and 519.611 liter per person per day (in 2023). While the necessity of clean water required both 586.260 liter per person per day (in 2018) and 556.470 liter per person per day (in 2023). In other words, the needs of clean water in Kecamatan Nasik until 2023 can not been able to cover necessity of clean water population yet.</p>

This paper examines the evolution of academic and applied approaches to analyze the problem of economic growth since the mid-XX century. For quite an extended period of time, these views were corresponding to universalist economic policies taking no adequate account of particularities and limitations that a certain catching-up economy embodied. New approaches analyzing the problems of economic growth, on the contrary, individualize growth diagnostics, structural transformation and the organization of reforms processes for the emerging economies. We argue that individualist approaches might be potentially more effective than the universalist ones for solving the problem of slow economic growth.
