Understanding the status and extent of spread of alien plants is crucial for effective management. We explore this issue using Australian Acacia species (wattles) in South Africa (a global hotspot for wattle introductions and tree invasions). The last detailed inventory of wattles in South Africa was based on data collated forty years ago. This paper aimed to determine: 1) how many Australian Acacia species have been introduced to South Africa; 2) which species are still present; and 3) the status of naturalised taxa that might be viable targets for eradication. All herbaria in South Africa with specimens of introduced Australian Acacia species were visited and locality records were compared with records from literature sources, various databases, and expert knowledge. For taxa not already known to be widespread invaders, field surveys were conducted to determine whether plants are still present, and detailed surveys were undertaken of all naturalised populations. To confirm the putative identities of the naturalised taxa, we also sequenced one nuclear and one chloroplast gene. We found evidence that 141 Australian Acacia species have been introduced to South Africa (approximately double the estimate from previous work), but we could only confirm the current presence of 33 species. Fifteen wattle species are invasive (13 are in category E and two in category D2 in the Unified Framework for Biological Invasions); five have naturalised (C3); and 13 are present but there was no evidence that they had produced reproductive offspring (B2 or C1). DNA barcoding provided strong support for only 23 taxa (including two species not previously recorded from South Africa), the current name ascribed was not supported for three species and, for a further three species, there was no voucher specimen on GenBank against which their identity could be checked. Given the omissions and errors found during this systematic re-evaluation of historical records, it is clear that analyses of the type conducted here are crucial if the status of even well-studied groups of alien taxa is to be accurately determined.

Abstract Heritage tourism is a significant contemporary facet of tourism in many developing countries. This paper analyses the economic opportunities for battlefield- heritage tourism in South Africa by examining the battlefields route within KwaZulu-Natal. Through structured interviews with stakeholders and structured questionnaires with visitors and local residents, this research explores the understanding of heritage tourism as well as perceptions of its influence on the physical landscape and gauges the importance of this form of tourism as a driver for local economic development in South Africa. Dundee, a small coal-mining town in KwaZulu-Natal, South Africa - where several battlefields are found, is used as a case study. The study demonstrates that several issues need to be addressed if this niche of cultural and heritage tourism is to be a sustainable and responsible form of tourism in South Africa.

This treatise is a case study that provides an insight into the status of private archives in South Africa with regards to their protection and access provisions. The paper is based on the author’s experiences as a manuscript librarian at the now defunct Lutheran Theological Institute (LTI) Library and Archives and research on faith-based archives which this institution was endowed with. The thesis of this paper is that records and archives legislation in South Africa as far as it applies to private archives is lethargic and not comprehensive enough to provide an enabling environment for their stewardship which is leading to loss of documentary heritage. The demise of this institution and the subsequent loss of the collection is testimony. In consequence, faith based collections (religious archives) need to be legislated like their counterparts public archives for protection and access in terms of the law.

Historically there has been confusion over the status and identification of Callitriche species in South Africa. Review of herbarium specimens and fieldwork have enabled confirmation of the presence of C. deflexa as a naturalised species in this country and confirmed that C. compressa and specimens named as C. bolusii are conspecific. Field surveys showed that C. compressa still occurs in the areas from which most historic collections were made with no evidence of a decline, it is widespread but local in Kwa-Zulu Natal and Eastern Cape Provinces and extends into eastern Western Cape Province. However because it is known from only five widely scattered sites, it is classed as Vulnerable under the IUCN Red List. We also typify here the names C. compressa and C. deflexa.

Thinking tomorrow, today is about generating and manipulating ideas proactively and progressively. The critical issue is about expanding the scope of understanding all the facets of the organisational activities, and maintaining same approach and strategy through the future in a sustained manner.  Manager’s ability should be screened on the basis of their pro-activeness and innovativeness in the management of thoughts that would foster the organisational advancement and effectiveness. This study is based on a case study design using secondary sources of data from a tertiary educational institution through an in-depth study and analysis of its organisational culture. Many of the early studies of this occurrence identified strong support for the idea that organisational culture and performance were indistinguishably linked. Recommendations given include the use of competitive and time effective management process to review, update, integrate, implement visions, decisions, and plans for tomorrow, whether in expansionary or recessionary times

This paper strives to make a case for the use of Northern Sotho as an indigenous official language in the post-apartheid South Africa. It contends that though Northern Sotho is constitutionally accorded the status of an official language in the new South Africa, it is marginalised in its practical everyday use as other languages still dominate it. The paper utilised Capricorn District Municipality in Limpopo Province as a case study that is grounded on the Qualitative research approach. It is, furthermore, underpinned by Ethnolinguistic Vitality and Afrocentric theoretical assumptions. Sampled data was collected by interviewing 24 Northern Sotho participants in the Municipality and was thematically analysed through the transcription of those interviews. The findings revealed that Northern Sotho does not enjoy the status that the Constitution of the Republic of South Africa (1996) has granted it. It recommends that this constitutional travesty be rectified by implementing the existing Language Policies as it erodes the identity of the marginalised speakers of the language.

Social movements came about as a result of dissatisfaction felt by society from the status quo. They present their grievances through demonstrations, strikes, riots, occupation of land, boycott of business or by the development of social and economic alternatives such as self-help schemes or saving clubs. In South Africa, people join housing co-operatives because it takes a long time to wait for the Reconstruction Development Project (RDP) houses promised by the Government. The leaning of 5 housing co-operatives was examined within the context of ideology and praxis that are components of triad model. This was done through multi-case study whereby the chairpersons of the housing co-operatives were interviewed using structured interview format. Findings from the study indicated that all the housing co-operatives were not open and voluntary; also, the housing co-operatives were not administered the same way. In all, efforts were put in by the housing co-operatives in engendering the ideology of co-operatives on one hand and the government on the other hand in providing the necessary subsidy so that the gap in the housing deficit could be bridged since this fitted its policy on housing.

Background: Southern African countries adopted diverse responses to the challenge posed by the COVID-19 pandemic outbreak, which manifested itself as both a health and economic disaster.Aim: Using a case study approach of two South African countries, namely Botswana and South Africa, the article assessed their response measures to the COVID-19 pandemic.Setting: Southern African countries applied ‘domesticated’ forms of responses thus, there has been no one-size-fits-all approach to managing the pandemic.Methods: The study adopted a qualitative approach. Two case studies namely Botswana and South Africa were used. Documentary evidence was drawn from these case studies.Results: To ensure that Southern African countries and indeed the world in general navigate the challenges posed by the COVID-19 pandemic, the World Health Organization (WHO) developed operational planning guidelines that had sought to balance the demands of responding effectively to COVID-19 and the need to serve economies from collapse. However, an analysis of the programmes of responses in South African countries such as Botswana showed the ‘domestication’ of the guidelines. Nevertheless, the guidelines, although having met with criticism in some cases had significantly contributed to the effective management of COVID-19 health and economic effects.Conclusion: The COVID-19 pandemic required the state and its institutions to exercise effective leadership and unified action. In South African countries such as Botswana and South Africa, this pandemic showed the importance of governments in shaping the effectiveness of national responses, strategies and approaches in tackling the crisis.

This paper addresses the fields of social and service design in development contexts, practice-based and constructive design research. A framework for social design for services will be explored through the survey of existing literature, specifically by drawing on eight doctoral theses that were produced by the World Design research group. The work of World Design researcher-designers was guided by a strong ethos of social and service design for development in marginalised communities. The paper also draws on a case study in Namibia and South Africa titled ‘My Dream World’. This case study presents a good example of how the social design for services framework functions in practice during experimentation and research in the field. The social design for services framework transfers the World Design group’s research results into practical action, providing a tool for the facilitation of design and research processes for sustainable development in marginal contexts.
