Abstract:

Economic growth rate differs largely between different countries. There are many opinions on which factors really affect the rate of growth in different economies and this causes debates. The factors that affect economic growth include political systems, social settings, economic freedom, human capital and institutional organization. These factors affect not only productivity, but also efficiency. This thesis’ purpose is to investigate and explain the factors that affect economic growth in sub-Saharan Africa. Through use of a fixed effects regression model, a panel data investigation will be c

Abstract:

A beach conservation programme protecting nesting loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) sea turtles in South Africa was started in 1963. As initial numbers of nesting females were low for both species (107 loggerheads and 24 leatherbacks) it was proposed that the protection of eggs, hatchlings and nesting females along the nesting beach would induce population growth and prohibit local extinction. Today, 50 years later, the loggerhead population exceeds 650 females per annum, whereas the leatherback population counts about 65 nesting females per year. The trend fo

Abstract:

Positive identification can be problematic if fingerprinting, DNA, dental history, etc. are no longer available. This may be possible through techniques such as facial approximation, but any form of craniofacial identification requires intimate knowledge of human craniofacial anatomy. Where children are involved, craniofacial changes due to facial growth further complicate matters and require knowledge of tissue thickness and variation in facial shapes. These have hardly been studied in children of African descent. The aims of this study were to provide data on tissue thickness and craniofaci

Abstract:

Certain aspects of the population dynamics of the brown mussel, Perna perna, were examined at 18 sites along the south coast of South African. Specifically the effects of wave exposure and tidal height were examined in relation to mussel size, biomass and density. A single set of samples was removed from each of the 18 sites, over three spring tide cycles. Sites were classified as exposed or sheltered prior to sampling. Principal component analysis (PCA) (based on mussel length data) and length frequency histograms revealed that there was a general decrease in the modal size of the adult musse

Abstract:

This study investigates the contemporary urbanization process of sub-Saharan Africa. The region is predicted to experience a surge in urban population growth the forthcoming decades, yet why and how this is happening is not very clear. Theory often considers urbanization to be a part of a modernization process where people migrate from rural areas to urban. But depictions of reality suggest that rural-to-urban migration might be less significant than previously thought, and neither is it given that urbanization causes prosperity in sub-Saharan Africa.

Abstract:

The two most frequently exploited species along the south east coast of South Africa are the gastropods, Haliotis midae (abalone) and Turbo sarmaticus (alikreukel). H. midae is a high valued commercial species, and suffers intense levels of illegal fishing. T. sarmaticus however, has no commercial value but is the preferred food item for impoverished subsistence communities. Owing to the fact that no legal commercial fishery exists for either species along the south coast, very few studies have been undertaken, especially in the heavily exploited infralittoral.

Abstract:

Africa is considered to be the second driest continent in the world after Australia. Sub-Saharan Africa (SSA) is the whole of Africa except North Africa; SSA covers around 80% of Africa’s total land area with a population of around 0.9 billion people. The continued population growth poses a challenge to systems that supply services in SSA; for example, in 1950, less than 200 million people lived in Sub-Saharan Africa, but in 2016 the population in SSA has increased to around 1 billion. Since the beginning of the 21st century, there has been a rising sense of urgency about the need to address m

Abstract:

Population dynamics of Perna perna in low shore mussel beds were investigated over a 15 month period at six sites along the south coast of South Africa, with particular reference to the effects of wave exposure. The degree of exposure was first quantitatively ascertained using the dissolution of cement blocks to measure average wave force and dynamometers to measure maximum wave force. The mean mass loss of the cement blocks was higher at Diaz Cross and Kwaai Hoek than at Mgwalana, Rufanes and Riet River. No data were available for Fish River.

Abstract:

Economists have studied the relationship between population growth and economic growth for a very long time and not found any clear relationships. Recently they have begun to focus on the factors of population growth such as fertility and mortality rates. From this line of study came the age-structure hypothesis. The age-structure hypothesis was founded on the evidence from Asia’s very successful demographic transition and many economists are now wondering whether Sub-Saharan Africa (SSA) will be able to repeat this feat. Hence, this study aims to investigate the relationship between the depen

The aim of this study was to investigate the effect of the IGF2 gene in the two South African populations with regard to meat and fat quality traits.

Abstract:

The Russian wheat aphid (RWA) (Diuraphis noxia Kurdjumov) is a major pest of cultivated small grains. It is particularly devastating because of is high reproductive rate which results in the growth of large populations which become damaging to its host plants. Development of resistant barley (Hordeum vulgare L.) cultivars is complicated as resistance is polygenic. As a result, the industry remains at risk now that the RWA has spread throughout South Africa. It has, as recently as, 2013, been identified in the SW Cape, which was previously geographically isolated. This is South Africa‟s princip

To provide for the housing needs o f people, precious agricultural land is being used, and the historic character o f towns is being destroyed. Densification of the city structure has been put forward as a solution to this problem. In this way, different components of the city may be connected and existing infrastructure may be optimally utilised.

The ichthyofaunal community structure, population dynamics and movement patterns in the small temporarily open/closed (TOCE) Grant’s Valley estuary, situated along the Eastern Cape coastline, were investigated over the period May 2004 to April 2005. Community structure in the littoral zone was assessed, while growth of selected ichthyofaunal species was investigated using the MULTIFAN model. Population size was assessed using mark recapture models and movement within the estuary using the Hilborn (1990) model. Total ichthyofaunal densities and biomass within the littoral zone ranged between 0.

Some towns have also changed the main focus of tbeir economy, for example, from that of mining to that of tourism, as in the case of Utrecht in Kwa-Zulu Natal (Nel, 2002).

The conclusion is that water scarcity is not the actual problem, but is perceived as the problem by policy-makers. Instead, water scarcity is the manifestation of the problem, with root causes being a combination of climate chang
