Full textAbstract:
The growth and accumulation of macroalgae in estuaries are a common sight throughout the world (Boyer and Fong, 2005). Because macroalgae establish such complex but important links with other components within an estuary, it is essential to know which variables control and regulate their occurrences. The type of algae that will occur in an estuary depends however, on the physical and chemical features of the particular estuary (Lobban and Harrison, 1994). The focus of this study was to document and provide a listing of algae from estuaries around the Eastern Cape coast of South Africa and describe the communities which form within each estuarine habitat. The questions posed were: Do algae assemblages differ in estuaries with different environmental conditions? Are different plant communities inhabited by different algae communities? Also, are algae diverse in estuaries that are in a pristine condition? The estuaries were Mngazana, Ngqusi/Nxaxo, Mtati, Mpekweni, East Kleinemonde, West Kleinemonde, Kariega, Bushmans, Kowie and the Sundays estuary. Percentage cover surveys were conducted and environmental parameters recorded to determine community structure of algae and their environmental tolerances. A total of 49 different macroalgal species were identified from 11 estuaries, which were dominated by Chlorophytes (23 species) and Rhodophytes (17 species). The Ochrophytes consisted of 10 species. The highest number of species recorded was 29 at the Bushmans estuary (March 2009), while the lowest number (4 species) was recorded at Mtati (October 2008). Common Chlorophytes found included Ulva prolifera, Chaetomorpha linum and Codium tenue. In the Division Ochrophyta, species from the Genus Ectocarpus were the most common. Of the red algae filamentous reds, Polysiphonia incompta and Polysiphonia kowiensis were the common algae found at estuaries. Salinity (p= 0.029861; n= 49) and temperature (p= 0.037641; n= 49) were the driving environmental parameters of estuaries and significantly influenced richness of species. In ordination analyses, patterns of biogeographic distribution were noticeable and were described by salinity. Four gradients caused by salinity were therefore found – which is inversely correlated to water clarity. Moreover, a clear split between temporarily open/closed and the permanently open estuaries was observed. Samples grouped into four communities presumably based on the similarity in conditions of estuaries. Within each estuarine community and major type of estuary there was a range of environmental conditions. However, the macroalgae within each community may not have been colonists of or found in greatest abundances in the estuaries of these communities per se, but may have grouped together in this manner based on the optimum growing conditions for them. Also, specific algal groups were not directly determined by the type of estuary they were found in; they were driven by environmental ranges rather. The results therefore support hypothesis one which states species distribution and diversity differ and are influenced by environmental gradients of the estuary. Although close species and habitat relationships were apparent from the ordination analyses, providing support for hypothesis two which states “Different plant communities in estuaries will be inhabited by different macroalgae communities”, the evidence was not substantial enough to provide sufficient support for the hypothesis. Lastly, the hypothesis “Macroalgae are diverse in estuaries that are in a pristine condition” was not accepted as highest species numbers were found in estuaries of greatest anthropogenic disturbance (e.g. Bushmans estuary) and not in estuaries which where ecologically more natural (e.g. Mtati estuary). By doing monthly macroalgal sampling over a period of one year for example one would obtain greater information of biodiversity, and patterns of macroalgal seasonality may be uncovered as well. This is an area of reasearch which needs to be investigated in the future as it would greatly add to the understanding of the role macroalge have in an estuarine environment.

Full textAbstract:
Many of the larger estuaries along the South African coastline are highly degraded due to human impacts, highlighting the need to conserve pristine systems. There are approximately 100 micro-estuaries along our coastline which have not yet been identified or classified and hence their ecological functioning is unknown. The aim of this study was to identify and classify micro-estuaries along the Eastern Cape coast. Specific objectives of the study were to: 1) map the distribution of estuarine habitats in a selection of micro-estuaries and assess changes over time; 2) measure the physico-chemical characteristics of the micro-estuaries in the field; 3) investigate the distribution of vegetation, identify macrophyte species and habitat integrity and classify the micro-estuaries sampled using abiotic and botanical characteristics. A total of 30 systems were identified of which 10 were selected for sampling which took place seasonally (2015-2016). A relationship between open water surface area and short term rainfall was only evident in Cunge, Sandy Bottom and Ichabana. In the field it was observed that after heavy rainfall, open water surface area increased and mouth breaching occurred. Salinity was the only water column characteristic that showed differences; salinity increased in response to over wash events. Sand was dominant in all systems and there were no differences in sediment characteristics. A total of 8 macroalgal species, 16 estuarine macrophyte species, six freshwater species and 72 riparian plant species were found. Seed bank reserves were low in all systems despite them being vegetated. Only abiotic characteristics were used for classification using Principle Components Analysis since there were no botanical differences between systems. Micro-estuaries were larger (> 0.03 ha), had a higher salinity (oligohaline, mesohaline and polyhaline conditions) and a constant water body. Micro-outlets were smaller (< 0.03 ha), had a lower salinity (oligohaline conditions were most common) and showed periods of drying. Five micro-estuaries (Shelbertsstroom, Kwesani, Cunge, Mtwendwe and Mtendwe) and five micro-outlets (Stromatolite, Sandy Bottom, Ichabana, Palm Tree and Black Rock) were classified. This study has shown that the micro-estuaries along the Eastern Cape coast are pristine (i.e. intact riparian zone and catchment), untouched and highly dynamic systems (i.e. great variation in water surface area and mouth condition) highlighting their need for protection.

Full textAbstract:
The project was initiated by Eastern Cape Parks (ECP) as a request for the construction of inventories of priority species and their population levels inside three nature reserves on the Eastern Cape Wild Coast, South Africa, and to develop a strategic management plan to manage these natural resources in each reserve. Thirty key species were identified by local communities in and around Dwesa-Cwebe, Silaka and Mkambati Nature Reserves through community workshops. For forested areas belt transects of 100 m x 6 m where used. The basal circumference of key tree species within the belt transect was measured as well as the height of saplings (height < 150 m). Tree species were categorized based on densities, size class distribution (SCD) curves and values, and spatial grain. For grassland areas straight transects of 200 m long were used, along which ten 3 m x 3 m quadrates were placed at 20 m intervals. Within each grassland transect the height of herbs or tuft diameter of grasses was recorded and percentage cover estimated. Grassland species were categorized based on density, SCD curves and percentage cover. All species were placed into harvesting categories based on analysed ecological data that was collected in the field. Category 1 species were very rare or not found in the reserve and it was recommended that species be conserved and monitored. Category 2 species had low densities in the reserve indicating declining populations and was suggested that these be monitored and not harvested. Category 3 species had high densities and have potential for harvesting with strict limitations. Category 4 species were most abundant with very high densities and can be harvested within management guidelines. These categories were grouped further using social and ecological data such as harvesting risk, frequency of collection, use value and number of uses. This highlighted which species have conservation priority within each category and a decision can be made as to how intense or limited extraction should be. By incorporating GIS the distribution of each species was looked at and harvesting and non-harvesting zones established to determine where species can be extracted. Monitoring plans must consider the quantity of plant material collected, fire regimes, optimal harvesting rates and harvesting zones, and be able to pick up changes in populations. Also, it is important that the community be involved in conserving and monitoring these species. Adaptive monitoring and management must be used to steer harvesting practices in the Wild Coast reserves. This allows for the development of harvesting practices through ‘learning by doing’, and the evolution of good questions to guide monitoring decisions

Full textAbstract:
An under-reported consequence of the democratic transition is the impact on land management (LM) within communal areas of South Africa (SA).Yet land is an essential natural resource, both for the survival and prosperity of humanity, and for the maintenance of all terrestrial ecosystems (FAO&UNEP,1997.)This study focuses on land management in the Wild Coast with special reference to indigenous people in Coffee Bay.Using the concept of the land management paradigm, the study adopts an intensive research design for the analysis and interpretation of data.The study aims to examine how land as a 'resource'is managed by the local indigenous people with special reference to wether it is moving towards or away from sustainability.The study discusses LM in the rural-built up environment with emphasis on land based activities, land tenure, gender issues,indigenous knowledge systems, changes in land use and degradation.The study looks at the indigenous people's participation in the new LM policy formation as predetermined by the grand scheme of democratization and decentralization.It highlights that indigenous knowledge systems are at the centre in rural sustainable LM, and equity in land issues forms another breakthrough for communal tenure system in the new SA.Indigenous people's views in policy formulation are not necessarily matched with national policy objectives due to poor public consultation.In general, the study provides an understanding of how indigenous people grapple with new policy changes in LM, to ensure sustainable land management in the rural South Africa

Full textAbstract:
It is evident that natural fish stocks are in rapid decline and that millions of people around the world rely on these resources for food and for securing a livelihood. This has brought many social scientists, biologists and fisheries experts to acknowledge that communities need to take more control in managing their natural resources. The paradigm shift in fisheries management from a top-down resource orientated control to a participatory people-centred control is now being advocated in many maritime nations in facilitating community-based natural resource management. At the heart of these projects is the establishment of institutions and social networks that allow for clear communication and information sharing, based on scientific data and traditional knowledge which ultimately allow empowered communities to collectively manage their resources in partnership with government, market actors and many other stakeholders. Central to the problem is the issue of access rights. In many situations where co-management of natural resources through community-government partnerships is advocated, the failure of coastal states to provide adequate legislature and regulatory frameworks has jeopardised such projects. A second issue is the failure of many states to provide adequate investments in social and human capital which will enable communities to become the primary stakeholder in the co-management of their natural resources. Whilst investments like capacity building, education, skills training and development, communications and institution building can initially require high financial investments, the regulatory costs for monitoring, controlling and surveying fish stocks along the coastline will go down as communities take ownership of their resources under sustainable awareness. The main unit of investment therefore is social capital which allows for the increase in trust, cooperativeness, assertiveness, collective action and general capabilities of natural resource governance. High levels of social capital require good social relations and interactions which ultimately create a social network of fishers, community members and leaders, government officials, market players, researchers and various other stakeholders. Co-management thus has an inherent network structure made up of social relations on a horizontal scale amongst community members as well as on a vertical scale with government and fisheries authorities. These bonding relations between people and the bridging relations with institutions provide the social capital currency that allows for a successful co-management solution to community-based natural resource governance. The South African coastline is home to thousands of people who harvest the marine resources for food security and securing a basic income. Fishing is a major cultural and historical component of the livelihoods of many people along the coastline, particularly along the Wild Coast of South Africa located on its South-eastern shoreline. Due to the geopolitical nature of South Africa’s apartheid past many people were located in former tribal lands called Bantustans. The Transkei, one of the biggest homelands, is home to some of South Africa’s poorest people, many of whom rely on the marine resources. By 1998 the government sought to acknowledge the previously unrecognised subsistence sector that lived along the South African coastline with the promulgation of the Marine Living Resources Act. The act sought to legalise access rights for fishers and provide opportunities for the development of commercial fisheries. The act and many subsequent policies largely called for co-management as a solution to the management of the subsistence sector. This thesis largely explains the administrative and legislative difficulties in transporting the participatory components of co-management to the ground level. As such co-management has largely remained in rhetoric whilst the government provides a contradictory policy regarding the management of subsistence and small-scale fishers. This thesis attempts to provide qualitative ethnographic research of the East Coast Rock Lobster fishery located in a small fishing village in the Transkei. The fishery falls somewhere on the spectrum between the small-scale and subsistence sector as there are a basket of high and low value resources being harvested. It will be argued that in order to economically and socially develop the fishery the social capital and social networks of the community and various stakeholders needs to be analysed in order to effectively create a co-management network that can create a successful collective management of natural resources thereby sustaining these communities in the future.

Full textAbstract:
Four species of dendrochirote holothurians, Roweia stephensoni John, Pseudocnella sykion Lampert, Aslia spyridophora Clark, Roweia frauenfeldi frauenfeldi Ludwig, and one aspidochirote holothurian, Neostichopus grammatus Clark, are common inhabitants of the intertidal regions of the eastern Cape rocky shores of South Africa. All five species are sympatric for most of their geographical distribution. The intertidal distributions, densities and biomasses of R. stephensoni, P. sykion and N. grammatus were examined at six sites from Port Elizabeth to East London in the eastern Cape. At all sites the three species showed similar overlapping zonations with R. stephensoni and P. sykion reaching their highest maximum mean densities and biomasses (drained wet weight) in the lower mid-shore region (401m² and 684g/m², 181m² and 269g/m², respectively at Port Elizabeth), whilst N. grammatus in the low-shore region (61m² and 72g/m², at Port Elizabeth). The highest densities and biomasses of all three species were recorded on boulder shores that had minimal sand inundation. Seasonality of reproduction of R. stephensoni, P. sykion and N. grammatus was compared at Port Elizabeth, using gonad index values, gonadal tubule diameters, egg diameters and spermatozoon content in tubules from January 1992 until August 1993. All three species are dioecious and did not deviate from a 1: 1 sex ratio. Sizes at first sexual maturity were 2.5-2.9 cm³ for R. stephensoni and P. sykion, and 3.0-3.9cm³ for N. grammatus. The gonads of R. stephensoni and P. sykion consist of a bunch of unbranched tubules of equal diameter, with males having more tubules of a smaller diameter than females. By contrast, the gonad of N. grammatus consists of two tufts of multiple branched tubules. All three species followed annual reproductive cycles, and in R. stephensoni and P. sykion gametogenesis occurred from March 1992 until August/September 1992, and maturity was maintained until the main spawning event in January 1993. By contrast, in N. grammatus gametogenesis occurred from July 1992 until September 1992, and maturity was maintained until the main spawning event in December 1992/January 1993. Unlike R. stephensoni and P. sykion the reproductive cycle of N. grammatus was more pronounced, in that the gonad regressed after spawning. Aspects of the feeding biology of R. stephensoni, P. sykion, A. spyridophora, R.ffrauenfeldi and N. grammatus were compared, using the gross buccal tentacle morphology, type and size range of ingested food particles, and gut lengths. Scanning electron microscopy revealed that the buccal tentacles of R. stephensoni, P. sykion and A. spyridophora could be classified as dendritic, branching numerous times with the tips terminating in numerous nodes covered with discs of papillate projections. The buccal tentacle structure of R. f frauenfeldi deviated from the typical dendrochirote dendritic form. The tentacles are stout with few branches which terminate in large bulbous nodes lacking discs of papillate projections. Neostichopus grammatus possesses buccal tentacles that could be classified as peltate, terminating in large nodes which also lacked discs of papillate projections. Roweia stephensoni, P. sykion and A. spyridophora are suspension-feeders, ingesting food particles mostly <53μm in size. Roweia f frauenfeldi was classed as a "heavy" suspension-feeder, ingesting food particles mostly between 250μm-1.18μm, while N. grammatus is a deposit-feeder, ingesting benthic sediments mostly between 106-500μm. The gut lengths of the dendrochirote holothurians were found to be significantly longer than that of the aspidochirote, and may be attributed to the nature of the food ingested.

Full textAbstract:
This case-study establishes the influences of power-knowledge relationships on capacity-building for sustainability in the European Union Funded ‘Wild Coast Spatial Development Initiative Pilot Programme’ (EU Programme). It aims to capture the lessons learned for capacitybuilding to support nature-based tourism initiatives on the Wild Coast. The EU Programme aimed to achieve economic and social development of previously disadvantaged communities through nature-based tourism enterprises, and to develop capacity of local authorities and communities to support environmental management. The study discusses common trends in thematic categories emerging from the research data, and contextualises research findings in a broader development landscape. This study indicates that power-knowledge relations were reflected in the EU Programme’s development ideology by an exclusionary development approach, which lacked a participatory ethos. This exclusionary approach did not support an enabling environment for capacity-building. This development approach, guiding the programme conceptualization, design and implementation processes, resulted in a programme with unrealistic objectives, time-frames and resource allocations; a programme resisted by provincial and local government. The study provides a causal link between participation, programme relevance, programme ownership, commitment of stakeholders, effective management and capacity-building for sustainable programme implementation. The study argues that the underlying motivation for the exclusionary EU development ideology in the programme is driven by a risk management strategy. This approach allows the EU to hold power in the development process, whereas, an inclusionary participative development methodology would require a more in-depth negotiation with stakeholders, thereby requiring the EU to relinquish existing levels of power and control. This may increase the risk of an unexpected programme design outcome and associated exposure to financial risk. It may also have a significant financial effect on donor countries' consultancies and consultants currently driving the development industry. This study recommends an interactive-participative methodology for programme design and implementation, if an enabling environment for capacity-building is to be created. In addition, all programme stakeholders must share contractual accountability for programme outcomes. This requires a paradigm shift in the EU development ideology to an inclusionary methodology. However, this research suggests that the current EU development approach will not voluntarily change. I, therefore, argue that South Africa needs to develop a legislative framework that will guide donor-funded development programme methodology, to support an enabling environment for capacity-building.

Full textAbstract:
Investigations were carried out on aspects of the biology of the vetigastropod Turbo sarmaticus. Studies included: 1) the distribution and standing stock of this animal at four sites along the coast of the Eastern Cape Province of South Africa; 2) the growth rate of animals on a wave-cut platform; 3) the reproductive cycle of an intertidal population; and 4) aspects of the feeding biology examining the ability of this mollusc to consume and digest six macroalgae, the influence of algal diet on growth rate and reproductive fitness and the polysaccharolytic activity of the digestive enzymes. On eastern Cape shores, T. sarmaticus had a size related distribution, with smaller animals being found towards the upper mid-shore and larger animals being found in a downshore direction. The mean shore densities of T. sarmaticus at three sites where exploitation of animals was minimal, were very similar (1.2 - 1.7 individuals/m²). The largest animals (up to 110 mm shell length) were found on an offshore island. This may have been a result of animals not being exploited, as well as a possible increase in primary productivity and food availability. The lowest density (0.2 individuals/m²) and animal size (<70 mm shell length) was recorded at a site (Kelly's beach - Port Alfred) where exploitation was more intense. It is probable that intense overexploitation was threatening the populations at this site. The growth rate of T. sarmaticus was determined by means of the von Bertalanffy growth model and expressed by the equation L[subscript]t = 81.07(l-e⁻°·⁵⁴⁴[superscript](t)). The initial growth rate of T. sarmaticus (up to ≈ 80 mm shell length) was similar on shores with different geomorphologies (i.e. boulder shores and wave-cut platforms). Growth rates of individuals were variable, which means that individuals within a population reached exploitable size (3 - 6 years old) and sexual maturity (1.5 - 2 years old) at different ages. Seasonality of reproduction of T. sarmaticus was determined using gonad index, egg diameters and spermatozoa content within the gonad. Turbo sarmaticus was dioecious and had a sex ratio in favour of males (1.2: 1). Animals attained sexual maturity at a size of about 52.5 mm shell length. There was little variation in the reproductive cycle over time with gametogenesis occurring from March/April until August/September, whilst maturity (Gonad Index = 15%) was maintained until the spawning event from December to March. After spawning the gonad regressed. Field and laboratory observations of the feeding biology of T. sarmaticus confirmed that this mollusc was a generalist grazer capable of consuming and digesting algae from the Rhodophyta, Chlorophyta and Phaeophyta. The consumption rates (juveniles: 1.45 - 9.50% body weight/day, adults: 1.06 - 6.08%) and digestibility (9 - 75% apparent dry matter) of six macroalgae was found to vary. For most algae, juvenile T. sarmaticus had higher consumption rates (1.6 - 2.8 times higher) and digestibility values (12 - 24% higher) than adults. It is suggested that consumption rates were dependent on the digestibility of the algae. In addition, it is suggested that the consumption rates of the different algae were not related to the nutritional content, but rather the energetic content of the algae. In both juvenile and adult animals, temperature had a positive influence on consumption rates, resulting in an increase at higher temperatures. However, in both juvenile and adult T. sarmaticus, algal digestibility was not affected by temperature. Finally, it was proposed that Viva rigida, Codium extricatum, Ecklonia radiata and Gelidium pristoides would provide the best nutritional value for growth and reproductive fitness in T. sarmaticus, whilst Jyengaria stellata and Corallina spp. would provide the poorest. Experiments on the effects of four algal diets on the biology of T. sarmaticus showed that the best growth rate (up to 13.8 mm shell length increase per annum), reproductive fitness (Gonad Index up to 33%) and energy levels (up to 4.76% glycogen in the foot) were achieved when T. sarmaticus was fed G. pristoides, U. rigid a or a mixed diet. Turbo sarmaticus fed Corallina spp. showed reduced growth (2.4 mm shell length increase), reproductive fitness (Gonad Index up to 4.4%) and energy levels (up to 3.42% glycogen in the foot). A study of the polysaccharolytic enzyme activity of T. sarmaticus indicated that this mollusc possesses enzymes that can, at least partially, digest most of the storage and structural polysaccharides found in the Chlorophyta, Rhodophyta and Phaeophyta. This further supported the findings that T. sarmaticus was a generalist grazer. Two levels of activity were detected: 1) high levels of enzyme activity (up to 328.2 Ilglmglmllhr)occurred on the storage polysaccharides that occur in the Rhodophyta and Chlorophyta, and 2) lower levels of activity were detected on the storage polysaccharides (up to 44.8 μg/mg/ml/hr) of the Phaeophyta and on all the structural polysaccharides tested (<45.5 μg/mg/ml/hr). It was suggested that T. sarmaticus did not rely heavily on structural carbohydrates as a source of carbon. Finally, the results of this study were discussed in relation to the future management of T. sarmaticus stocks, the possible role of this macro algal grazer in the intertidal zone and the effects of over-exploitation of this animal. The potential aquaculture of this mollusc was also addressed briefly.

Cape Peninsula University of TechnologyThe study investigated tourism as a catalyst to local economic development of the Transkei Wild Coast. The Transkei Wild Coast is an area which stretches from the Kei River mouth south of East London, to Durban South Coast, with seven local municipalities located in the area. These local municipalities are Mquma, Mbhashe, King Sabata Dalindyebo, Nyandeni, Port St Johns, Ngquza Hill and Mbizana. Infrastructure and partnership models were identified as key to the development and growth of the tourism industry in the Transkei Wild Coast. It was found that the status of infrastructure and partnerships is lacking and delivers little or no economic benefits and advances in the Transkei Wild Coast. Factors contributing to the poor performance of tourism-led local economic development by the local municipalities in the Transkei Wild Coast include poor roads, poor communication, lack of infrastructure, erratic electricity supply, and poor quality of water supply. Partnerships both at strategic and implementation levels lack commitment, role clarification and acceptable beneficiation metrics to all involved stakeholders. Infrastructure and partnerships are explained as basic and key necessities in developing a successful tourism industry in the Transkei Wild Coast. The study argues that local municipalities need support to grow the tourism industry to become a key contributor to the local economic development strategy. The Transkei Wild Coast has a wealth of natural resources, culture and history to offer tourists to this area. Local economic viability of the Transkei Wild Coast will improve, which inevitably will lead to an improved standard of living of the host communities. Growth of the tourism industry will lead to growth and development of related industries/businesses. The findings revealed that the majority of Transkei Wild Coast inhabitants support investment in the tourism industry. Prioritisation of tourism as a catalyst to local economic development in the Transkei Wild Coast will unlock other potential economic sectors in the area. For this to succeed, it is imperative that capital infrastructure is improved and credible and beneficial partnerships are created and maintained. Recommendations are proposed to fulfil the State-led mandate for socioeconomic development and advancement at local municipal level in South Africa generally and the Transkei Wild Coast in particular.

Full textAbstract:
The South African abalone Haliotis midae Linnaeus, 1758, is an important commercial, recreational and aquaculture mollusc species. It is the largest of the six haliotid species found in South African waters and has the second largest distributional range aside from Haliotis spadicea which is widely exploited by rock and surf anglers as bait. Analysis of population structure at Great Fish Point revealed that H. midae exhibited a high degree of microhabitat specificity, and that while dietary habits played a role in habitat selection, it was ultimately the activities of predators which confined size classes to particular niches and restricted all animals to nocturnal activities. Large (> 100 mm SL) exposed animals relied on shell thickness and adhesion to combat predators, while small (> 45 mm SL) sub-boulder animals and medium sized (50 - 95 mm SL) animals relied on their cryptic microhabitats and the protective spine canopies of co-resident urchins (Parechinus angulosus) for daytime protection. Populations of H. midae were discontinuously distributed along the coast, occupying small isolated reefs which offered a suitable array of microhabitats and a good food supply. They mostly inhabited shallow intertidal and subtidal reefs, but were occasionally encountered on deeper subtidal reefs at 4 - 5 meters. Mean length- and width-at-age were determined from growth rings composed of alternate conchiolin (dark) and aragonite (white) bands in the internal nacreous shell layer. Growth was described by the Special Von Bertalanffy growth equation: Lt(mm) = 176.998918 (1 - e⁻°·²⁴²⁴¹⁹⁽t ⁺ °·⁴⁹⁵⁴⁹⁴⁾) Wt(mm) = 159.705689 (1 - e⁻°·¹⁹⁵⁴³⁹⁽t ⁺ °·²¹¹⁶⁾) The ageing technique used was validated for animals from Great Fish Point and Mgwalana using independent tag-return data. The same data provided evidence that growth rates varied between animals from Great Fish Point and Bird Island. The growth data also showed that H. midae exhibited a high degree of individual variation in growth rate. Males and females exhibited similar growth rates. Exposed large animals showed a preference for red seaweeds, in particular Plocamium corallorhiza and Hypnea spicifera, while small sub-boulder cryptic animals included larger proportions of brown (Ralfsia expansa) and green (VIva spp.) algae in their diets. Exposed individuals also exhibited a higher degree of selectivity towards prey items, but in general, stomach contents reflected the most abundant seaweed types. Both drift and attached algal species were utilized by H. midae which was a nocturnal feeder. Pigments from red algae were incorporated into the shell layers giving the shells a pink or brick red colour. Haliotis midae is a dioecious broadcast spawner. Gonad Bulk Indices in combination with detailed histological examination of gonads showed that individuals were iteroparous, asynchronous spawners and that the breeding season extended from March through to October, although the peak spawning activity was between April and June. Males and females can spawn partially, totally or not at all, with atresia of residual gametes occurring after spawning. There is no resting stage, and gametogenesis is initiated directly after spawning. The structure of the ovary and testis and the process of gametogenesis is typical of haliotid species. AI: 1 sex ratio was observed from all populations studied. Sexual maturity was first attained in the 40 - 59 mm SL size class, although evidence for the smallest size at first spawning was recorded at 54.6 mm SL for females and 69 mm SL for males. Sizes at 50% sexual maturity were 72.5 mm SL (52.8 mm SW) at Great Fish Point, 72.5 mm SL (57.4 mm SW) at Mgwalana, 73.7 mm SL (51.2 mm SW) at Cape Recife, and 73.5 mm SL (53.8 mm SW) at Kelly's Beach. Haliotis midae was typically highly fecund, although a high degree of variation resulting in poor relationships between fecundity/shell length and gonad weight/shell length. The relationship between fecundity and gonad weight was linear. In the Eastern Cape, H. midae possessed a faster growth rate, smaller size at sexual maturity, smaller maximum size and lower longevity when compared to con specifics in Western Cape waters. A smaller minimum legal size of 93 mm SW is proposed for Eastern Cape animals and it is suggested that the closed season be moved to the peak spawning period between April and June. The benefit of a closed season during the spawning period is questioned, and the feasibility of closed areas as a management option for H. midae in the Eastern Cape is discussed.

Full textAbstract:
Development for sustainable poverty alleviation requires engagement with the values and cultural frames that enable or constrain communities to steward ecosystems and maintain their capacity to support human well-being. Rooted in a social-ecological systems (SES) perspective, this thesis explores the concept of sense of place to understand how emotional and cultural connections to place mediate human responses to change and influence interventions for development. Sense of place is both the attachments to place, as well as the descriptive meanings to which one is attached. Paper I presents an approach and agenda for studying sense of place in SES that emphasizes place attachment and meaning underlying stewardship actions and responses to change. This is empirically explored through a case study on the Wild Coast, South Africa - an area with multiple contested meanings. In this former Bantustan (an area set aside for black South Africans), Apartheid created interdependence between small-holder agriculture and labour migration, where rural homesteads relied on remittances from migrant household members. Today, the contribution of agriculture to livelihoods has declined and many households rely on income from social grants. Interacting social and ecological factors in this region have resulted in social-ecological trap conditions and circular migration continues to be the pattern. Community conservation and ecotourism is one strategy for local socio-economic development. Papers II and III explore community tensions around a proposed nature reserve declaration. In Paper II, a focus on the meanings of locally-defined ecotopes (e.g. forest and abandoned fields) illuminates the interpretations of underlying social-ecological processes. Paper III examines the use of place meanings in narratives of change to show tensions in the discourse of win-win conservation. The stalling of this particular intervention indicates the importance of engaging with multiple meanings of place and the cultural importance of nature. Papers IV and V focus on declining agriculture and continued labour migration. From a theoretical model of people’s abilities, desires and opportunities, Paper IV develops a typology of responses that may contribute to maintaining or resolving social-ecological traps. For this case study, the model identifies the mismatch between i) cultural expectations that frame the desire to farm, and ii) the decline in opportunities for off-farm income to support agriculture. Paper V demonstrates that these expectations are expressed in the idea of emakhaya (the rural landscape of home) as well as reinforced through cultural rituals. The paper identifies a place-based social contract between the living and the ancestors that helps to maintain circular migration and agricultural practices. This suggests that sense of place contributes to system inertia but may also offer opportunities for stewardship. Sense of place is socially constructed as well as produced through experience in ecosystems, and thus constitutes an emergent property of SES. The thesis demonstrates the use of participatory methods to produce an inclusive understanding of place and SES dynamics. The application of place meanings through these methods facilitates critical engagement with imposed interventions. Finally, the thesis shows that sense of place and culture are key for understanding inertia in SES and the capacity for transformation towards stewardship.At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: Manuscript.

Full textAbstract:
This study endeavours to elucidate the journal of Captain Hermanus Hofmeijer of the Dutch man 0' war, Amsterdam, which has been transcribed from the original script, translated from Dutch into English and interpreted from a contemporary viewpoint. It offers an opportunity to evaluate a unique primary historical document which records an important historical event. An attempt has been made to contextualise the incident in the light of the early history of the Dutch people. The contribution of the Dutch East India Company (VaC) to the trade and commerce of the Netherlands during the 17th and 18th centuries has been assessed together with the shipbuilding techniques that served to make the Dutch a major seafaring nation. The significance of Texel and Nieuwediep has been examined and the sea route and navigational instruments placed in perspective. The voyage has been analysed in some detail. The background of Captain Hermanus Hofmeijer has proved especially interesting. Although he pursued his career with the Dutch Navy, he was born and spent his early years in Cape Town, South Africa. The time spent by the Amsterdam in Batavia, Samaraog and Sourabaya gives an insight into the Dutch possessions overseas. The return voyage, storms and ultimate grounding are of special interest as Hofmeijer records the journey and events on a daily basis. The impact and significance of 217 extra people in the Eastern Cape area did not go unnoticed, and although the event was not well documented, an attempt at some contextualisation has been made. Finally a short overview of maritime archaeology in South Africa and its significance as a relatively new discipline has been included. The study of the material remains of the wreck of the Amsterdam has resulted in a new understanding of wooden ships built in the early 19th century.

The study was looking at achieving more cost-effective implementation of the Eastern Cape Thicket Rehabilitation Project. Project management has been identified as a key for a proper implementation of any kind of work. For project management to be effective, individual learning and development of project managers is of paramount importance. An improved communication process is vital, that clearly specifies objectives if any success will be achieved. A proper and structural way of addressing change is a need, so that no unnecessary delays are experienced. A need is there for processes to be streamlined to avoid duplications as they are unnecessary costs. Employees need to be given an opportunity to have their ideas looked at, a way of testing if they really have been empowered. The important thing is that their views must speak to the standards of the project. Reductions in costs are a must for more communities to benefit in the project. Continuous improvement is the way forward.

Full textAbstract:
In today’s dynamic technological landscape, wireless communication networks have become an important part of economic development. The emergence of wireless technologies raises hopes to extend communication to remote areas that have not seen any tangible deployment to date. As developing nations pin their hopes to wireless technologies, cost models for wireless communication networks are becoming vital to support the emerging technologies. However, varying cost changes raise critical challenges to the estimation of both capital expenditure and operational expenditure. The network deployment process has numerous events that may cause adjustments to initially estimated project costs. These adjustments are necessary for a cost management plan and this plan includes monitoring cost performance and ensuring that only appropriate changes are made to the network project. The incidents that may cause cost changes can not be entirely predicted as their distribution tend to change dynamically from time to time. Estimating network deployment costs in such a dynamic environment necessitates cost models that can adapt to random occurrence of cost changes. Widely used cost models are usually performed by experienced personnel whose engineering experience is derived from deploying similar networks. In this approach experienced personnel add a certain percentage to the cost estimate to cater for contingency costs. Certainly such an approach depends on individual opinion, making it subjective and void of mathematical estimating relationships which are of paramount importance in ensuring that estimated deployment costs are sufficient to deal with cost uncertainties. We observe that existing approaches can only explore a limited solution space and hence can lead to cost overruns if implemented in dynamically cost changing environments. This thesis presents a wireless communication network deployment cost model that incorporates uncertainties into the final cost estimate. The model is adaptive to unpredictable cost changes since it allows adjustments of confidence levels when calculating contingency costs. This allows dynamically updating the cost changes without the cost model being reconstructed from scratch. We make use of the Poisson process in modeling the occurrence of incidents that are responsible for causing cost changes during network deployment. We also show that the occurrence of the incidents causing cost change are random and tend to follow the Poisson distribution. Using different levels of confidence we model various cost contingencies and make sensitivity analyses to identify the probability of cost overrun when given different contingencies. The dynamic adaptive cost model can be used either at the strategic level to understand the cost of a particular technique or at the operational level, as a way to show how Poisson process in network deployment can compare with engineering experience and other estimating techniques. We believe that the model is useful for remote areas where deployment costs are volatile and the distribution of incidents causing cost change to original cost estimates are diverse and dynamically changing. Further we expect that our research improves the knowledge base of information about the costs for rural communities to connect to the Internet, consequently providing useful input to future policy debates. This work is further poised to be a utility function to help those planning internet infrastructure deployments in least developed regions.

This paper investigates the rationale of using standard costing in modern manufacturing organisations. Researchers argue that standard costing does not easily fit in with the modern idea of continuous improvement. The benefits and limitations of standard costing and other modern alternative approaches in Eastern Cape manufacturing organisations are examined. Furthermore the factors affecting the accuracy of standards are investigated. Lastly, it is concluded that standard costing is used in Eastern Cape manufacturing organisations and those organisations using standard costing have considered the benefits and limitations.

The development of electronic commerce (e-commerce) is the most visible business use of the World Wide Web. The primary goal of an e-commerce site is to sell goods and services online. This project deals with developing an e-commerce platform for marginalized communities of the Eastern Cape region, South Africa. An online “shopping mall” to support the marketing of art and crafts from disadvantaged communities is presented, with Linux-Apache-MySQL-PHP (LAMP) as the development environment. Free and Open Source Software has been chosen to develop the virtual shopping mall system because the use of Open Source allows easy localization and extensions to the system developed and long term sustainability, as the source code is available. Also, it might start a “virtuous” circle, whereby young members of the communities hosting art and craft makers become involved in maintenance, and then production, of software systems. One important design constraint from the e-commerce platform presented in this thesis is the possibility for the art and craft makers to manage their shops directly, from the initial loading of their wares to the day-to-day maintenance, such as changes of price or items. The user requirement elicitation and initial field testing were conducted in Dwesa, an area on the wild coast, South Africa. The system currently comprising two shops is live at the time of writing this thesis at www.dwesa.com.

1.1 Background to, and motivation for, the study: The Working for Water programme (WfW) is a public works programme designed to clear South Africa of water-consuming invasive alien tree and plants, and to replace them with low water consuming indigenous species. This would prevent a loss of more than 4000 million cubic metres water per annum from the hydrological cycle (DWAF, 1998). The economic viability of the programme has been established in the Western Cape and Kwazulu-Natal (van Wilgen, Little, Chapman, Görgens, Willems and Marais, 1997; Gilham and Haynes, 2001), but questioned in the Eastern and Southern Cape (Hosking, du Preez, Campbell, Wooldridge and du Plessis, 2002). Hosking et al. (2002) investigated the economic case for the programme by performing a Cost Benefit Analysis (CBA), based on increased water yield and livestock potential, on six selected sites in the Eastern and Southern Cape, viz.

There is little understanding of the implementation efficiency and effectiveness of restoring plant invaded landscapes within operational contexts. South Africa's Working for Water (WfW) programme is arguably the most ambitious alien plant control programme in the world, yet little is known about its cost-effectiveness and the challenges it faces in linking poverty and environmental objectives. My first aim was to assess the cost-effectiveness of invasive plant removal, and the factors that underpin its effectiveness over large spatial and temporal scales. The second aim was to compare the accuracy of evidence-based findings with managers' experience-based beliefs, and to assess whether managers are willing to change their beliefs after being exposed to it. The third aim was to assess the costs and benefits of removal versus removal followed by active native re-vegetation. My final aim is to assess the challenges and lessons learnt by managers linking ecological restoration with poverty alleviation objectives, specifically within the public works model. My study area was focused primarily on two WfW river catchment projects in the western region of the Eastern Cape province. I adopted an interdisciplinary approach drawing from a range of methods such as observational studies, statistical modelling and interviews with managers. The key findings were that control efforts in the two catchment projects are largely inadequate owing to many sites being re-invaded and not enough resources being allocated to the catchments. It would take between 54 and 695 years to clear the respective catchments. In terms of cost-effectiveness, my results exceeded previous estimates by 1.5 to 8.6 times for each catchment project. After being exposed to the evidence-based findings, the managers did not change their beliefs when it came to forecasting the future effectiveness. I found that active native re-vegetation after removal of invasive plants is very costly and that priority should be given to understanding the effectiveness of the removal treatments on native species recovery. The managers cited significant challenges in effectively and efficiently meeting the programmes dual objectives. Based on a broader review of the public works literature I recommend WfW re-examine the type of public works they currently use.

Bibliography: leaves 185-205.A more recent approach to communal rangelands argues that this traditional view has ignored communal farmers' objectives, which are to maximise stock numbers rather than offtake in the form of sales and slaughter, and challenges the view that communal rangelands are necessarily degraded. Long-term livestock records in many former homeland districts of South Africa have shown no appreciable long-term decline in animal numbers. This has led several influential researchers and policy makers to conclude that no loss in productivity has occurred and that these systems are sustainable in fulfilling the objectives of the land users. The aim of this study is to assess the costs of degradation in terms of land users' objectives using a case study in a communal rangeland area in South Africa.

Full textAbstract:
Thesis (MTech (Construction Management ))--Cape Peninsula University of Technology, 2010The motivation of the public sector is more social and political. The housing crisis is a major political issue for every ruling party. In many countries there are political commitments to housing, but sadly we witness this commitment being misdirected. Every government wants to see that its citizens are housed adequately. Very often it is seen that in its endeavour, government try to follow the private sector process, establishing huge parastatals to carry out the whole process, for example design, construction and financing (Lankatilleke, 1994). Lankatilleke, L. (1994) further mentions that mass produced public sector housing schemes are aesthetic disasters. They are either rows of match-boxes or high-rise blocks with no identity or individuality. There are numerous examples of such housing schemes that have deteriorated into ghettos. This research consequently presents findings which implies that government is being pressurized by the housing backlog within the Western and Eastern Cape, which brings about time constraints and tight budgets. These pressures are transferred to the design teams which need to speedily produce designs for low-cost housing homes within the best possible budget. This results to the implementation of common model designs. It is also founded that contractors ultimately suffer, due to these pressures which do not allow them to produce good quality homes. It is therefore recommended that better community involvement for sustainable methods in the design and construction process should be practiced. This therefore concludes that government should take more responsibility for the delivery processes of low-cost housing as well as the procurement and quality systems to be followed.

Full textAbstract:
One of the serious problems facing South Africa is that of the provision of adequate low-cost housing for the poorest of poor. Only about 56% lived in fully-owned formal dwellings in 2009. (Stats SA: 2009). The problem is not only about the inability of the government to decrease backlogs in the provision of adequate low-cost houses. These contributory factors include the standard of construction, land as well as continuous urbanisation. International commitments such as the UN’s Millennium Goals put further pressure on government to permanently resolve the issue. Adequate housing is recognised globally as a basic human right. This includes access to running water and sanitation and electricity. The aim of the study is not to investigate construction techniques or methods, specific choices of location or any other planning-related issues, but to find an approach that is more appealing to the challenge of the provision of housing as per the afore-mentioned challenges combined with, amongst others, the provision of the necessary resources and relevant political processes as well as monitoring and evaluation. The provision of low-cost housing is unique in nature as it can never be fully resolved. To assist the process because of its nature, future studies suggest systems theory as a best recognised and more successful way to address wicked problems. By investigating low-cost housing programmes in Chile and Australia, identifying the elements of systems theory used, it was possible to find pointers to help formulate a set of steps (or actions) to use to address South Africa’s low-cost housing challenge. This research report proposes that, while the challenge of housing provision in a country like South Africa will most probably always be present, it can be alleviated by applying systems thinking to the problem. The study therefore puts forth Participatory Housing Delivery Monitoring Model (PHDMM). The model will assist in providing the beneficiaries of low-cost houses space to participate in the housing process and projects. It will also necessitate accountability by various participants in housing development. Capacity building will also be part of the package.

Access to adequate water and sanitation services in South Africa still remain a pipe dream for the millions who are trapped at the bottom of the class structures in the country. The poverty stricken communities living in Townships such as Motherwell, everyday long for water services infrastructure to be built in their places of residence. The costs of accessing water services also becomes a setback for many consumers in the area, this is after the infrastructure has been installed in their areas. The high unemployment rate plays an enormous role in many consumers not affording water services. Bureaucracy between the government department of Housing and the NMMBM also impedes delivery of water services for without formal housing, water and sanitation is impossible to be accessed within the households. The study revealed from the semi-structured interviews which were held with Mayoral Council official and Ward Councillors as well as with members of the communities NU 12 and 29 that access to adequate water services was not successful and satisfactory. The findings of the research demonstrate that the Municipality has a problem with retaining staff members in the portfolio of Infrastructure, Engineering, Electricity and Energy, which is the responsible department for providing water and sanitation services to the local inhabitants. This study was conducted from April 2009 to November 2009 and it was aimed at finding the Barriers to accessing water services in the Motherwell Township.

There are three lines of poverty in South Africa, the first line is that of people living at less than R271 per month and constitute one third of the population (about 33 percent), second being those people living at less than R422 per month (50 percent of the population) and the last group being people living at less than R1 230 per month, constituting 79.1 percent of the population (Oosthuizen. 2008: 7 – 9). The poorest provinces are Eastern Cape and Limpopo with a poverty rate of 68.3 percent and 60.7 percent respectively, Western Cape and Gauteng the poverty rates are 20 percent and 28.8 percent respectively (United Nations Development Programme. 2003) To respond to the poverty challenges the government has come up with poverty alleviation strategies which were later translated into anti-poverty programmes. The Anti-poverty programmes undertaken by Government since 1994 can be grouped into various categories of public expenditure such as (Friedman and Bhengu, 2008:14), Social assistance and grants, Employment generating programmes, enterprise development and income support, Basic household security, Social services, Disaster relief and Employment related social insurance. This study assessed Mogabane Community Project to find out reasons why the project did not reach its objective of poverty reduction in the community.

Full textAbstract:
Tourism is widely perceived as an easy access, low-impact means to achieving economic growth and development. In South Africa, community-based tourism has been promoted as a way of delivering resources and services to historically marginalised areas, and as a means by which rural communities can begin to exercise more control over the decisions and resources that directly affect the quality of their lives. A history of deliberate underdevelopment during apartheid, has left the Wild Coast region with high unemployment, widespread socio-economic poverty, limited infrastructure; and a pristine coastline of 'untapped' tourism potential. Given its incompatibility to other forms of development, tourism has been identified by government as a key sector for driving economic development and poverty alleviation along the Wild Coast. This study reviews four tourism enterprises in operation along the Pondoland Wild Coast in terms of their 'pro-poor' credentials (net benefits to local communities), socio-economic impact, participation and ownership by local communities, institutional establishment, and environmental sustainability. The selected operations exemplify different models of community and private sector involvement in tourism development on communal land. A wide range of investigative methodologies from primary and secondary data analysis, interviews, structured questionnaires, surveys, and quantitative assessment criteria, were employed in this study. The key findings and recommendations from the case studies are then considered in light of the developmental opportunities and constraints pertaining to the region. This study revealed that the Pondoland Wild Coast is faced with numerous socio-economic and environmental challenges. The principal limitations to sustainable tourism development include lack of basic infrastructure and services, prevailing tenure insecurity, unclear legislation and overlapping jurisdictional mandates, direct environmental threats such as a proposed toll road and mining, haphazard/illegal developments, and a poorly defined spatial planning framework. Whilst all four tourism enterprises appeared to be underpinned by sustainable development principles, they differed widely in the nature and size of benefits they provided, and their degree of institutional, economic and environmental sustainability. The findings and conclusions drawn from this study are intended to contribute towards the theory, practice and sustainability of 'pro-poor,' 'community-based', and 'responsible' tourism development, and assist future tourism development planning in the region.Thesis(M.Sc.)-University of Kwazulu-Natal, Pietermaritzburg, 2004.

A dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science in Medicine in the Division of Human Genetics
Pretoria, 2016Oral history and anthropological data indicate that several Xhosa clans in the mPondoland region of the Eastern Cape (formerly the Transkei) were established by individuals of non-African ancestry. Several oral and few written accounts state that circa 1730, survivors from trade- and slave-bearing vessels shipwrecked along the Wild coast of the Eastern Cape. Castaways who had survived the shipwrecking events had assimilated with the indigenous people of the area, married local women, and established clans of their own. The group of clans, which claim their ancestors to be of European and/or Eurasian descent, are known as the abeLungu, meaning “the Whites”. These clans are discerned from other local groups by variations in the practice of rituals from that of traditional Xhosa rituals, as these clans retain an affiliation with the European culture to which their ancestors belonged. Nowadays they still retain subtle phenotypic features like blue eyes, which are seen in several clan members. The identity of these clans has, to date, been shrouded in myth due to conflicting versions in the oral history and anthropological data, which leave the picture of the cultural identity of the abeLungu people unresolved. With the advent of molecular biology, it has been shown that DNA may be used as a tool to trace population ancestry. The non-recombining region of the Y chromosome (NRY) serves as a marker for patrilineal ancestry and similarly mitochondrial DNA, which is inherited from mother to progeny, serves as a record for the matrilineal human history. This study aims at exploring the degree of agreement between culture and genetics by investigating the genetic variation of the abeLungu - a culturally and geographically defined group. Focus is placed on their patrilineal history, since their oral history indicates clan progenitors to be predominantly male, but also due to the patriarchal social structure with regards to marriage and kinship of the abeLungu. Buccal swabs were taken from which extracted DNA was used to perform Y chromosome microsatellite short-tandem repeat (STR) and SNP minisequencing using a total of 60 SNPs and 19 STRs taken from 146 abeLungu clan-affiliated individuals and 42 non-clan members from the greater region of mPondoland. Mitochondrial DNA SNP determination and sequencing analyses were also performed on 188 males and 10 females (the wives/ direct relatives of primary male clan elders), so as to trace the matrilineal origins and examine the congruence between the molecular and anthropological data. The frequency of European and Eurasian haplogroups in the male samples was 69.86%, which are delineated predominantly by European haplogroups R1b, and West Asian haplogroup R1a1a. Haplogroups G, I and Q which occur at high frequencies in Europe and Eurasia were observed as well. It has also been observed (which was as expected) that culturally defined groups with a unique (or a limited number of) common origins whose membership is inherited only through the male line showed a relatively low intragroup variation for genetic markers similarly transmitted. The maternal lineages of the abeLungu clan members segregate with ancient and deeply-rooted African haplogroup L lineages, with increased diversity on account of migration due to their exogamous marriage practices. This study affirms the non-African paternal origin of the abeLungu clans of lineages originating from few distinct founders, and elucidates the previously unresolved oral accounts of genealogical information, which has been transferred across generations with considerable accuracy, despite its propensity for change over time.

Full textAbstract:
Despite the fact that the Wild Coast area is well endowed with natural resources, the area is severely underdeveloped and experiencing high levels of unemployment. It is against this background that the South African government has chosen tourism as an appropriate development instrument for Port St. Johns. The empirical evidence shows that coastal tourism development has produced benefits such as employment and
income generation in countries like Kenya, which share the same development trends with the Eastern Cape. Thus, the Wild Coast Spatial Development Initiative (WCSDI) has been proposed as a vehicle to promote tourism development. The WCSDI aims at unlocking the inherent and under-utilised economic potential of certain specific spatial locations, like Port St. Johns. In this study a critical analysis of the tourism-related projects proposed for Port St. Johns is undertaken, making use of cost-benefit analysis techniques and drawing on projections made in the course of the WCSDI planning process. The study shows that these projects can lead to economic growth through attracting investment and creating employment opportunities. However, this study does not show the exact number of jobs created by this development, as most of these projects are still in the planning stage. Lessons should be drawn from the Kenyan Coastal Development Corridor case study, in order to ensure that the WCSDI is a success.Thesis (M.Com.)-University of Natal, Pietermaritzburg, 1999.

Full textAbstract:
Intertidal size-frequency distributions and densities for Haliotis midae and Turbo sarmaticus were examined at 10 sites experiencing varying pressure of human exploitation along the southern section of the Eastern Cape coast, South Africa. Target species' densities and maximum sizes were related both to the numbers of collectors on the shore and to indirect indicators of exploitation such as number of households in the vicinity and distance to the nearest beach access point. For both species, there was variation in density (P < 0.05) and size (P < 0.05) among sites, with densities ranging between 0.03-2.23 m^(-2) and 0.07-4.93 m^(-2) for H. midae and T. sarmaticus, respectively. Maximum sizes ranged between 49.4-153.5 mm (H. midae) and 28.3-104.4 mm (T. sarmaticus) shell length. Population parameters such as mean maximum size and total density were significantly negatively related to exploitation indicators for both species. In addition, densities of sexually mature and legal-size individuals of T. sarmaticus were significantly negatively related to the number of households. However, only for H. midae were densities of subadults significantly negatively related to the number of collectors, suggesting that reproduction of abalone may be suppressed at the most exploited sites. Exploitation of T. sarmaticus tends to be localized near population centres, whereas H. midae is collected over a larger range of sites. Overall, T. sarmaticus is less affected by exploitation than H. midae.

The objective of this research is to investigate the food security, food diversity and coping strategies used to access food in households in the Eastern Cape rural village of Timane in Idutywa, Eastern Cape, South Africa.
A cross-sectional survey design was used in which a Coping Strategy Index questionnaire designed by Maxwell and Caldwell (2008) and a HDD questionnaire was used to gather data interviewing respondents. This study was conducted in the rural community of Timane which was divided into geographical groups from which household were randomly chosen. A total of 60 adults representing 60 selected households were interviewed to provide information on household dietary diversity.
Data was collected on the socio-biographic and HHD parameters of households. Data was analyzed and presented as correlation, percentages, means and SDs. Up to 72% of household received state grants and the Spearman’s correlation between number of children and HDD score was r = 0.38 while that between number of adults in households and HDD score was r = -0.93. Food security in the Timane community largely depends on state grants and HDD increases moderately with the increase in children and decreases with the increase in adults per household. The majority of the households (72%) received state grants as a source of income within which old-age pensions constitute 28% and child grants 38%. The Spearman’s correlation coefficient between the number of children in households of respondents and CSI was 0.78 (P < 001) while that between the number of adults in households and CSIS was 0.2 (P < 001).
Household in the rural community of Timane community were found to be food insecure and this gets severe with the increase in the number of children in households.Life & Consumer Sciences

Full textAbstract:
As enshrined in the post-apartheid South African constitution, access to basic services like potable water, sanitation and formal housing has become a basic right for all South Africans. The delivery of low-cost housing through the national and provincial Departments of Human Settlement is one of the major focuses of the post-apartheid South African Government. South Africa today (2010) still has massive shortages of low-cost housing for the poor, despite funding being made available to address this need. Millions of poor families live in shacks in informal settlements and in overcrowded townships where small (250 to 300 square metre) erven with one bedroom dwellings and rudimentary extensions and backyard shacks erected on them often house more than one family while they await access to housing subsidies. The Eastern Cape Province is one of the poorest provinces in South Africa, with a significantly poor rural community and dense urban settlements which have sprouted all over as a result of urban migration and population growth. According to the Provincial Human Settlement Department, the Eastern Cape has a backlog of approximately 370,000 low-cost houses. Several low cost housing projects have been initiated in the province. The projects are implemented using different partnership strategies and they produce different outcomes, which are in no way near the desired outcomes of meeting the demand of supplying quality houses in the shortest possible time (E Cape Government Department of Human Settlement).
In terms of the project management norms, standards and processes of the building industry, it takes two builders, one plumber and five labourers five days to build a fifty square metre low-cost housing unit. Yet
some projects, as small as 200 housing units, have taken more than 10 years to complete for one reason or the other. Often when the houses are perceived to be complete it becomes evident that their quality is of an unacceptable standard, and some unmet desired objectives. Some project sites in rural towns of the former Transkei have been abandoned due to failures in implementation. Furthermore, some project sites which start off as green fields have been invaded by poor communities who build rudimentary shack dwellings on the sites in a sign of desperation, impatience and frustration at the pace of delivery (among other reasons) with a huge unfavourable financial impact on the implementation of the planned projects. The problems impacting on low-cost housing delivery are a combination of hard systems (processes, procedures, costing, programming and so on) and soft systems (the human element). The problems and risks described as being associated with housing projects are many and varied, depending who is talking, and in some instances it is difficult to describe the problems in words (unstructured and complex problems). This study concentrates on the human element associated with the implementation processes by critically examining the roles of the multitude of stakeholders who are identified as partners in the projects. Such partnerships are a huge contributing factor to the success or failure of a programme. This study looks at minimising project implementation risks through the establishment of effective cross-sector partnership frameworks. The positive and negative impacts of partners in low-cost housing project management and implementation are critically examined using Soft Systems Methodology (SSM) with a view to improving service delivery.

Past research on activity-based costing (ABC) success factors has predominantly
focused on establishing relationships between known success factors and ABC
implementation success. According to the researcher, there is a lack of exploratory
studies to establish ABC implementation factors especially in a South
African context. This study has explored these factors from literature and
attempted to identify any other factors of importance with the use of semistructured
interviews. A total number of 13 interviews were conducted with
participants from manufacturing organisations in the Nelson Mandela Bay
Metropole using some form of ABC. The findings suggested that ABC may be
more beneficial at larger, more diverse organisations but that smaller organisations
may also benefit from ABC if product costing accuracy could be
significantly improved with ABC and if no major pressure on company resources
is incurred. In addition it seems that ABC should be utilised to the fullest extent
that is practical for the manufacturing organisation and that the use of
supplementary cost-saving mechanisms with ABC may be beneficial. Finally it
is recommended that users be fully trained at ABC and that careful consideration
of an appropriate ABC software package may increase the likelihood of ABC
implementation success.Management Accounting

Full textAbstract:
The desire of modern democratic governments is to provide basic amenities for its citizenry and the present South African Government has indicated this in several of its documents including the document on Reconstruction and Development. The question of adequate shelter has been identified as one of the burning issues that require urgent and immediate attention. However, the question still remains: "Is the state the best organ of society to be directly involved in the actual provision of housing or is this function best left to the private sphere of society, above all, private society and Non-Governmental Organisations (NGOs)?". This dissertation considers the methods and other related ways in which to assist the poorest of the poor in meeting their housing needs through the intervention of Non-Governmental Organisations. In attempting to do this, the study looks at a case study of an NGO that has been involvedin housing provision. The aim is to find out whether this sphere of housing activity is best suited for NGOs especially where the issues of the poorest of the poor are concerned. The thesis reviews various international as well as local cases pertaining to housing provision and contribution towards finding interventionist approaches to be adopted in order to realise the desires of the new democratic government in housing for all.Thesis (M.Sc.U.R.P.)-University of Natal, Durban, 1997.
