“…Other reasons attributed to this pertains to improved transport accessibility and rising car ownership in the urban periphery combined with the aggregate cost reducing advantages resulting mainly from the availability of land at relatively cheaper prices at these locations. An initial study by Oduro et al (2014), for example, established that in 2010, some 90.5 % of the sub-region's population lived within 4 km distance of a major road, implying that transport infrastructure development has played a major role in the patterns of physical development.…”

“…In recent years, a number of empirical studies have sought to understand urban expansion trends in the sub-region. Using OpenStreetMap and Google Earth, Oduro et al (2014), analyzed drivers of urban growth in the subregion. Cobbinah and Amoako (2012), estimated historical land-use distribution in the Kumasi metropolis-the historical core of the sub-region between 1995 and 2010.…”

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.

“…Population growth has been emphasised as a main driver of land use change, especially in developing countries [41,42]. Census data show that between 1984 and 2010, Kumasi's population increased with a growth rate of over 5% per annum [39], making it one of the fastest growing cities in Ghana [43] and implying an expansion of the built-up area [44]. The changes observed in the Owabi catchment are consistent with those observed in many studies conducted at national and regional levels in Ghana [6,41,[45][46][47].…”

Land Use and Land Cover Changes in the Owabi Reservoir Catchment, Ghana: Implications for Livelihoods and Management

et al. 2019

Reservoir catchments in Ghana have undergone significant changes in recent years with major implications for socio-economic development and local livelihoods. We studied land use and land cover changes and their impacts on livelihoods in the Owabi reservoir catchment from 1970 to 2014 using Landsat, ERDAS Imagine and Arc Geographic Information System (ArcGIS 10.2) software supplemented with participatory approaches including focus group discussions, key informant interviews and questionnaire surveys with 400 households. Our results showed that, since 1970, 24.6% of high-density forests and 15.8% of sparse forests have disappeared, while the built-up area has increased from 9.8% to 56.6%. Additionally, the proportion of bare soil (areas that do not have vegetation cover due to forest clearing and other anthropogenic activities) has increased, while the areas of waterbodies have declined. We identified urbanisation and lack of community involvement in catchment management as the key factors driving the land cover changes that have adversely affected the livelihoods of the local fringe communities. This study highlights the threats from urbanisation to land cover changes and identifies the key drivers of land use change. For effective and sustainable management of natural resources, the local communities should be more actively involved in the decision-making process regarding the management of their individual catchments.

“…The two locations are both in the Ashanti region of Ghana which lies in the tropical savannah zone of Africa and have no differences in climate (Figure 1). 12,13 Kumasi is an urban and heavily industrialized city and the capital of the Ashanti region. It is the second largest and second most populous city in Ghana with an estimated population of 3.3 million people and a density of about 14,000 people/square kilometers.…”

Aim: To compare differences in clinical dry eye features and meibomian gland health status between dry eye patients from rural and urban populations in Ghana. Methods: We examined 211 (rural=109, urban=102) participants with subjective dry eye symptoms. Tear film break-up time (TBUT), Schirmer's test and ocular surface staining (OSS) were assessed. Symptoms were evaluated using the SPEED II questionnaire. Meibomian glands (MG) in the right eye upper (UL) and lower lids (LL) were imaged using a custom meibographer. MG area was determined by intensity threshold segmentation using Image J software. MG loss (MGL) was also graded based on Pult's grading scheme. Mann-Whitney, Spearman correlation, chi-square and odds analyses were performed; p<0.05 was considered significant. Results: Rural participants showed greater SPEED scores, reduced TBUT, and lower Schirmer scores, p <0.05. The proportion of rural participants with MGL were significantly more (82.3%) than urban participants (63.3%), p <0.05. They also showed greater MGL than urban participants, p <0.05. Chi-square test revealed significantly different meiboscale distributions (UL: χ 2 =13.58, LL: χ 2 =15.29) between the groups, p <0.05. Overall significant relationships were observed between MGL and age [r s = 0.61], OSS [r s = 0.35], TBUT [r s = −0.52], and Schirmer scores [r s = −0.40], p <0.05. Conclusion: The data suggest that the participants from the rural population have worse dry eye and meibomian gland health status than those from the urban population. The significant relationships between the various clinical variables suggest important links between MGD and DED. Subtle differences in the everyday working and living environment could likely account for the differences in the severity of DED and MGD between the two groups. And considering the increased pattern of urbanization, industrialization and modernization and the related environmental effects in Africa, future longitudinal studies on specific environmental risk factors or mediators of DED and MGD are necessary to ascertain the MGD and DED situation in Ghana and Africa at large.
