“…On the one side, it presents wide-ranging opportunities for socio-economic development, largely in the form of the creation of economies of scale, both internal and external, as well providing the requisite climate for the maximization of the micro-economies of agglomeration-sharing, matching and learning (Duranton and Puga, 2004). On the flip side, it presents many challenges, including stress on infrastructure, congestion, urban poverty, environmental degradation, food insecurity, and a host of other urban planning and management problems (Ravallion et al, 2007;Chen, 2007;Watson, 2009;Eigenbrod et al, 2011;Baloye and Palamuleni, 2015).…”

Over the years, urbanization has triggered complex spatial processes, such as the evolution of city-regions that defy traditional administrative regional boundaries. However, despite the growing body of research on city-regions, the evolution of this phenomenon and its implications for contemporary spatial governance remains a huge gap in urban planning literature, while approaches to their delineation have largely been restricted to commuting patterns data and approximations. This research examines the emergence of city-regions and their implications for contemporary spatial governance using Ghana as an illustrative case. In the process, inspired by Tobler's first law of geography and the concept of distance decay, the study engages a unique methodological approach that uses spatial mapping of rural-urban population continuum, transportation network, built-up patterns and GIS techniques for the delineation of city-region. The research finds a gap between the rapidly emerging spatial structure of Accra and the operational governance framework, as there is no provision in the latter for the planning and management of the evolving city-region which, territorially, spans multiple administrative regions. At the local context, while making the lagging spatial governance system more responsive to the dynamically evolving spatial structure, it is imperative that urban policy recognises city-regions, such as the Accra City Region (ACR), and their diverse opportunities; plan for them through joint development planning boards; and foster natural coordination even among local planning authorities across different administrative regions. At the global scale, the research practically illustrates that alternative methodologies based on spatial mapping and GIS techniques could provide useful insights into the study of city-regions.

“…The emerging challenges of climate change, environmental degradation and resource depletion resulting from decades of rapid urbanization (Watson 2009), pose serious threats to public health, the continuous supply of essential eco-system services and food security (Eigenbrod et al 2011;Baloye and Palamuleni 2015).…”

Quantifying the spatio-temporal patterns of settlement growth in a metropolitan region of Ghana

Retrospective understanding of the magnitude and pace of urban expansion is necessary for effective growth management in metropolitan regions. The objective of this paper is to quantify the spatialtemporal patterns of urban expansion in the Greater Kumasi Sub-Region (GKSR)-a functional region comprising eight administrative districts in Ghana, West Africa. The analysis is based on Landsat remote sensing images from 1986, 2001 and 2014 which were classified using supervised maximum likelihood algorithm in ERDAS IMAGINE. We computed three complementary growth indexes namely; Average Annual Urban Expansion Rate, Urban Expansion Intensity Index (UEII) and Urban Expansion Differentiation Index to estimate the amount and intensity of expansion over the 28-year period. Overall, urban expansion in the GKSR has been occurring at an average annual rate of 5.6 %. Consequently, the subregion's built-up land increased by 313 km 2 from 88 km 2 in 1986 to 400 km 2 in 2014. The analysis further show that about 72 % of the total built-up land increase occurred in the last 13 years alone, with UEII value of 0.605 indicating a moderate intensity of urban expansion. Moreover, the metropolitan-core of the sub-region, being the focal point of urban development and the historical origins of expansion, accounted for more than half of the total built-up land increase over the 28-year period. Over the last decade and half however, urban expansion has spilled into the neighbouring peripheral districts, with the highest intensity and fastest rate of expansion occurring in districts located north and north east of the subregional core. We recommend a comprehensive regional growth management strategy grounded in effective strategic partnerships among the respective administrative districts to curb unsustainable urban expansion.

“…One example is a posthoc analysis, which is used to compare mean difference between groups. Several remote sensing studies have used this method (Giraldo, et al, 2009;Jalili, 2013;Baloye & Palamuleni, 2015). Meanwhile, some other studies used summary statistics such as descriptive, means and variances or more complex summaries of seasonality and environmental variability in order to gather and understand particular subjects (Cringoli et al, 2004).…”

ABSTRACT:Land cover type is an important signature that is usually used to understand the interaction between the ground surfaces with the local temperature. Various land cover types such as high density built up areas, vegetation, bare land and water bodies are areas where heat signature are measured using remote sensing image. The aim of this study is to analyse the impact of land surface temperature on land cover types. The objectives are 1) to analyse the mean temperature for each land cover types and 2) to analyse the relationship of temperature variation within land cover types: built up area, green area, forest, water bodies and bare land. The method used in this research was supervised classification for land cover map and mono window algorithm for land surface temperature (LST) extraction. The statistical analysis of post hoc Tukey test was used on an image captured on five available images. A pixel-based change detection was applied to the temperature and land cover images. The result of post hoc Tukey test for the images showed that these land cover types: built up-green, built up-forest, built up-water bodies have caused significant difference in the temperature variation. However, built up-bare land did not show significant impact at p<0.05. These findings show that green areas appears to have a lower temperature difference, which is between 2° to 3° Celsius compared to urban areas. The findings also show that the average temperature and the built up percentage has a moderate correlation with R 2 = 0.53. The environmental implications of these interactions can provide some insights for future land use planning in the region.
