In South Africa, outbreaks of African horse sickness (AHS) occur in summer; no cases are reported in winter, from July to September. The AHS virus (AHSV) is transmitted almost exclusively by Culicoides midges (Diptera: Ceratopogonidae), of which Culicoides imicola is considered to be the most important vector. The over-wintering mechanism of AHSV is unknown. In this study, more than 500 000 Culicoides midges belonging to at least 26 species were collected in 88 light traps at weekly intervals between July 2010 and September 2011 near horses in the Onderstepoort area of South Africa. The dominant species was C. imicola. Despite relatively low temperatures and frost, at least 17 species, including C. imicola, were collected throughout winter (June–August). Although the mean number of midges per night fell from > 50 000 (March) to < 100 (July and August), no midge-free periods were found. This study, using virus isolation on cell cultures and a reverse transcriptase polymerase chain reaction (RT-PCR) assay, confirmed low infection prevalence in field midges and that the detection of virus correlated to high numbers. Although no virus was detected during this winter period, continuous adult activity indicated that transmission can potentially occur. The absence of AHSV in the midges during winter can be ascribed to the relatively low numbers collected coupled to low infection prevalence, low virus replication rates and low virus titres in the potentially infected midges. Cases of AHS in susceptible animals are likely to start as soon as Culicoides populations reach a critical level.

Public Service Delivery

This study examines the influence of knowledge management (KM) practices on public service delivery by municipalities in the Eastern Cape province of South Africa. The study sought to determine the factors that have triggered the implementation of KM practices; the effectiveness of KM practices towards public service delivery; and the extent to which KM practices have influenced public service delivery by municipalities in the Eastern Cape province of South Africa. Both quantitative and qualitative methods were employed in this study. Quantitative data were collected through a survey questionnaire administered to a sample of 202 employees at the Raymond Mhlaba Municipality in the Eastern Cape. Qualitative data were collected through observations and interviews of 2 senior managers. The data collected gave a response rate of 72 per cent. The quantitative and qualitative data were analysed descriptively and presented verbatim respectively. The results indicated that the internal and external factors included in this study have contributed to the implementation of KM practices in the municipality. Furthermore, the effective use of KM practices has increased the organisational KM initiative, as well as the provision of services such as electricity, education, transport, and social services by the municipality. The study recommends the establishment of KM awareness and the establishment of an integrated system that will assist in effective knowledge sharing, retention and acquisition across municipalities in the Eastern Cape.

Government Communication

ABSTRACT This paper used qualitative methodology to explore the South African government communication and land expropriation without compensation and its effects on food security using Alice town located in the Eastern Cape Province South Africa as its case study. This was done to allow the participants to give their perceptions on the role of government communication on land expropriation without compensation and its effects on South African food security. In this paper, a total population of 30 comprising of 26 small scale farmers in rural Alice and 4 employees from the Department of Agriculture (Alice), Eastern Cape, South Africa were interviewed to get their perception and views on government communications and land expropriation without compensation and its effects on South African food security. The findings of this paper revealed that the agricultural sector plays a vital role in the South African economy hence there is a great need to speed up transformation in the sector.
