The high rate of migration, coupled with population increase triggered rapid urbanization. However, a great proportion of the population still lives in substandard and low quality houses in a deplorable unsanitary residential environment particularly in developing countries. Urban and Economic growth have brought about all typical problems associated with rapid urban development resulting in housing shortage both quantitative and qualitative, slums, illegal settlement and squatting as experienced in owerri municipality. These have resulted into many urban and housing problems within the state capital owerri. This study examined the nature of urban growth and housing problems in owerri municipality. Also it tries to examine residential housing stock, identity the nature of housing problems, government policies and programmes in other to address the problems. The pattern of growth was determined using spatial analysis, and the housing problems were identified through questionnaire and field surveys. Findings revealed that the growth of urban housing in owerri municipality increases by 1034.0 hectare which is equivalent to 38.5% which is in line with Maurice (2004). It was also discovered that over a period of time, new settlements have evolved. Also, the construction and expansion of road networks are evidences of urban growth in owerri municipality.

Freshwater System

<p>Human population is progressing into a predominantly urban configuration. Currently, 3.5 billion people – 55% of the total human population – live in urban areas, with an increase to 6.68 billion (68%) projected by 2050. In this progressively more populated world, a central issue of sustainability assessments is understanding the role of cities as entities that, despite their comparatively small physical footprint (less than 0.5% of the global area) demand resources at regional and global scales.</p><p>Many of the resources that sustain urban population directly depend on the freshwater system: from direct fluxes from/to the immediate environment of cities for water supply or waste elimination, to water-dependent activities like biomass (food, biofuels, fibers) and energy production. Urban and freshwater system interactions are subject to multiple sources of non-linearity. Factors like the patterns of size or spatial distribution and interconnection of groups of cities; or the nested and hierarchical character of freshwater systems, can vastly influence the amount of resources required to sustain and grow urban population; likewise, equivalent resource demands can be met through different management strategies that vary substantially in their cumulative pressure exerted on the freshwater system.</p><p>Here we explore the non-linear character of those interactions, to i. identify water management options to avoid, minimize or offset regional impacts of growing urban populations, and ii. explore long term implications of such non-linearities in sustained resource base of urban areas. We propose a framework integrating three elements: 1. properties of the size and spatial distribution of urban center sizes, 2. scaling regime of urban energy resource dependencies, and 3. scaling regime of associated physical and ecological impacts in freshwater systems.</p><p>An example of this approach is presented in a case study in the Magdalena River Basin – MRB (Colombia). The basin covers nearly one quarter of Colombia’s national territory and provides sustenance to 36 million people, with three quarters of basin inhabitants living in medium to large urban settlements of populations of 12 000 or more inhabitants and 50% concentrated in the 15 largest cities. The case study results indicate that freshwater-mediated resource dependencies of urban population are described by a linear or super-linear regime that indicates a lack of scale economies, however, freshwater systems’ capacity to assimilate those resource demands is characterized by a sublinear regime. As a result, current practices and technological approaches to couple freshwater and urban systems will not be able to withstand the resource demands of mid-term future population scenarios.  Our approach allows to quantify the projected gaps to achieve a sustained resource base for urban systems in MRB.</p>

Network Pattern

After a brief counter-urbanization of the early 1990s, rural out-migration resumed in Russia. Population concentrates in large settlements, while small and medium-sized towns and villages lose people. The farther rural settlements from regional center the greater the outflow of people. Centripetal tendencies can be mitigated or amplified at local level, where specific conditions of the area come to fore. The authors suggest settlement network pattern as one of such contextual factors, whose effects on population dynamics are still poorly understood. The paper poses two questions: what the effects of settlement network topology on the rate of population concentration are, and how population dynamics in individual settlements depends on their position in settlement network. Based on a case study of Tyumen oblast of Russia the authors investigated population dynamics in 2002–2010 with methods of network, cluster and regression analysis. The authors did not find relationship between density and centralization of settlement network and rate of population concentration. However, the study revealed a significant role, played by the network position in determining individual settlements population increase/decrease. Together with initial population size, the network position explained 23–24% of the variance in population dynamics among the towns and villages of Tyumen oblast. Outside the Tyumen metropolitan area settlements with highest inter-district network centrality grew. It is noteworthy that configuration of the regional settlement network at inter-district level emerged during the period of colonization of Western Siberia in 17–19 centuries. The configuration largely stems from the river network. Thus, even if the factors, which determined settlement network pattern, have lost their force, the settlement pattern itself continues to affect social space.

In the past few decades, urban growth in most parts of the world has disregarded sustainable practices, contributing to a myriad of global problems. With 68% of the global population projected to reside in urban areas by 2050, it is essential that we espouse and implement effective sustainable solutions immediately. This study focuses upon the smart sustainable practices adopted at the international headquarters of The Art of Living near Bengaluru, the ‘Silicon Valley of India’. Situated in a rapidly urbanizing area barely 20 kms from the busy metropolis, and characterized by a large floating population that varies from 3,000-6000 visitors per week, apart from almost 2000 residents, this bustling community has lush green cover, extremely rich biodiversity and excellent air quality. Some of the sustainable practices adopted here include permaculture, efficient waste management, moving towards the use of clean energy, etc. This paper posits that this unique community exemplifies the possibility of creating an ‘oasis of sustainability’ in the arid desert of urbanization.

The rapid increase in the urban population in Africa has created many urban challenges, including informalities, waste management problems, increased health risks, and growing urban poverty. With the unplanned spatial patterns and informalities that exist with the current urban population, this raises the question of whether African cities are ready to host more than 1.3 billion people by 2050 and still achieve urban sustainability. Using Ghana as a case study, this research undertook a critical review of urban population trends and their relation with economic growth. It identified the actors of urban governance in Ghana, as well as their roles, contributions and level of participation in urban governance processes. Findings indicate that most urban management decisions in Ghana are made by the government and exclude the non-governmental actors and citizens who bear the outcome of such decisions. This has resulted in deficiencies in actualising local needs, thus hindering the provision of urban services. The study proposes an inclusive and participatory form of urban governance with active participation of non-governmental actors and a paradigm shift from the existing urban management approaches to a more sustainable one that delivers socioeconomic benefits for more inclusive and sustainable cities in Africa in the future.

This article promotes the value of GIS methodologies to integrate and analyze a range of historic sources dating to the eighteenth century, utilizing Charleston, South Carolina as a case study. Data compiled from the 1790 Federal Census, the 1790 Charleston trade directory, and Ichnography of Charleston 1788 provide vital and complementary evidence that allows the population of the city to be located, which in turn provides a means of assessing late eighteenth-century residency patterns and the enslaved urban population. The value of data visualization is explored, underscoring the need for historians to engage with visual representations of data to communicate research results.

Abstract A rapid increase in population and unsustainable land use changes that are not following its capability are likely to lead to severe urban problems. An analysis of the carrying capacity and holding capacity of the environment is needed to determine whether lands can sustain the increasing population. The present research aims to identify the environmental conditions of the Kecamatan Barat based on the carrying capacity and holding capacity of land, water, and demography. Further, an overlay analysis is used to understand the overall carrying capacity level of the sub-district. Qualitative descriptive analysis is used to elaborate the study results. Two villages have deficits in the carrying capacity and capacity of land in West District in 2020, including Purwodadi and Tebon. Six villages are experiencing a water deficit in 2020, including Purwodadi, Karangsono, Bogorejo, Tebon, Manjung, and Mangge. All villages in Kecamatan Barat are still able to accommodate the projected population increase until 2042. The overlay of land, water, and demographic carrying capacity and water holding capacity shows 8, 4, and 2 villages with very high, high, and low overall carrying capacity values.
