Thesis (MBA)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: The South African economy is faced with a number of challenges as an upper-middle income country that is highly resource-intensive, with an open economy. It has a number of developmental goals that must be achieved in order to maintain environmentally conscious sustainable development. The country will have to find pioneering ways to address the poverty problems faced by a large proportion of its people, while still ensuring economic growth at a reduced cost to the environment. In an effort to promote the shift to a “green

Abstract:

Urban green spaces and trees are increasingly recognised as crucial elements in the quest for urban sustainability internationally, and for the promotion of urban liveability and quality of life in cities. So much so that many countries now have guidelines or regulations regarding either the amount of urban greenery that must be provided per capita, or the maximum distance that any dwelling can be from green spaces of stipulated sizes. For example, the European Union recently more than doubled its recommendation of 9 m2 of public green per person to 20 m2 per person.

Abstract:

The nutrient dynamics in two contrasting estuaries and in the adjacent nearshore environment along the south-east coast of South Africa was investigated seasonally. Due to an inter-basin transfer of water from the Gariep Dam to the Great Fish River, the Great Fish estuary is a fresh water dominated, terrestrially driven system with an annual fresh water inflow of 250 – 650 x 10⁶ m³ per year. In contrast, the Kariega estuary is a fresh water deprived, marine dominated system with a fresh water inflow estimated at 2.5 – 35 x 10⁶ m³per year. The reduced fresh water inflow into the estuary is attr

Thesis (MBA)--Stellenbosch University, 2011.<br>The world as we know it is in a warming cycle. The rate of warming is being exacerbated by human activity; more specifically, the burning of fossil fuels to power expanding economies. Awareness that something must be done before a catastrophic point of no return is reached, has become more urgent. Before any strategies can be developed to reduce greenhouse gas emissions, the levels must be accurately measured to provide a benchmark and to determine reduction targets. The determination of an organisation’s carbon footprint is thus the starti

The disease spectrum of NAFLD extends from steatosis (types 1,2) to non-alcoholic steatohepatitis (NASH) with inflammation (types 3,4). The aims of the study were 1) to analytically validate high-throughput real time polymerase chain reaction (RT-PCR) assays for three selected single nucleotide polymorphisms (SNPs), FTO rs9939609 (intron 1 T>A), TNF-α rs1800629 (-308 G>A) and PPARγ rs1801282 (Pro12Ala

Abstract:

In the KwaZulu-Natal (KZN) Midlands North region of South Africa, the importance and increased prevalence of endemic scarabaeids, particularly Hypopholis sommeri Burmeister and Schizonycha affinis Boheman (Coleoptera: Melolonthinae), as soil pests of sugarcane, and a need for their control was established. The development of a mycoinsecticide offers an environmentally friendly alternative to chemical insecticides. The identification of a diversity of white grub species, in two Scarabaeidae subfamilies, representing seven genera were collected in sugarcane as a pest complex. Hypopholis sommeri

Abstract:

South Africa, strategically situated at the southern tip of Africa, is edged on three sides by almost 3000 km of coastline surrounded by the Indian Ocean and the Atlantic Ocean (South African Tourism, 2011). This vast ocean expanse is responsible for conveying approximately 96% of South Africa’s exports (Brand South Africa, 2011). Despite the positive economic effects of the shipping industry, translocation of harmful organisms and pathogens via ballast water and sediments inside ballast water tanks has far reaching global environmental (and economic) impacts (Oliviera, 2008:1; David and Golla

Abstract:

This thesis looks into the land use and natural resource management systems of Basarwa communities in Ngamiland in the northwest of Botswana. The study specifically focuses on Basarwa communities living in and on the edges of the Okavango Delta. The link between these communities and their natural resources is explored using the Sustainable Rural Livelihoods Framework and the Adaptive Renewal Cycle. The core assumption in this thesis is that livelihood strategies are constantly renewed and adapted to promote resilience in ecological and social systems. Fieldwork data collected between May 2000

Abstract:

Since the study on the Port Alfred/Kenton-on-Sea/Boknes linefishery by Hecht and Tilney (1989) there have been substantive changes to the linefish management environment in South Africa. Using the Port Alfred linefishery as a model, the aim of this study was to evaluate the effectiveness of the linefish management regulations that were implemented by Marine and Coastal Management (MCM) since 1992, and to assess the behaviour and 'status' of the fishery in response to these changes. Changes to both the licensing structure and catch regulations have had a significant effect on the functioning of

Abstract:

The protozoan parasite Trypanosoma congolense is one of the aetiological agents of African animal trypanosomiasis that is transmitted by the tsetse fly. The parasite causes nagana in animals and affects livestock throughout sub-Saharan Africa. The toxicity of available drugs and the emergence of drug resistant parasites have affected the treatment of trypanosomiasis. Control of the disease has also been difficult due to ineffective vector control and the potential of trypanosomes to express hundreds of antigenetically distinct proteins on their surface. Vaccination against trypanosomiasis has

Abstract:

African animal trypanosomiasis is a major threat to African agriculture causing a loss estimated to 4.5 billion US$ per annum. Trypanosoma congolense is the major causative agent in African animal trypanosomiasis and is transmitted by tsetse flies of the Glossina spp. Congopain, a major cathepsin L-like cysteine peptidase in T. congolense is associated with trypanotolerance in N‘Dama cattle and is a target for an anti-disease vaccine. It is suggested that trypanotolerant cattle control the disease by antibody mediated neutralisation of congopain, and that immunisation of cattle against congopa

Abstract:

Environmental degradation is a global challenge that affects all. One of the most prominent impacts of environmental degradation is the climate change phenomenon. The adverse impacts of climate change have given rise to responses aimed at retarding, halting and learning to live with the already present effects of climate change. These responses to climate change fall into two broad categories: mitigation and adaptation. Mitigation addresses the climate change challenge through seeking a reduction or elimination of anthropogenic generated greenhouse gas emissions into the atmosphere. Adaptation
