The East African freshwater crab Potamonautes obesus (A Milne-Edwards, 1868) (family Potamonautidae) is redescribed from a large series of specimens from Tanzania and Somalia, and Potamon (Potamonautes) bottegoi de Man, 1898 is judged to be a junior objective synonym of P. obesus. The related taxon, Potamonautes calcaratus (Gordon, 1929) from Mozambique and South Africa, is recognised here as a valid species and is redescribed from type material. The distributions of P. obesus and P. calcaratus are described and discussed.

Providing access and usage are the reason for existence of memory institutions such as archive repositories. Despite the importance of the visibility and accessibility of public archive repositories, various scholars concur that these repositories in eastern and southern Africa are not known and are accessed by few people. This chapter utilises the concept of soft power as a framework to examine the visibility and accessibility of public archives repositories in South Africa. A quantitative research approach utilising questionnaires, interviews, content analysis and the observation of landmarks were employed as data collection tools. The findings revealed that collaboration, especially with civil societies, is a key for successful public programming at the lowest cost. It concludes that the concept of soft power can provide deep insight and better understanding on how to develop inexpensive visibility programme, yet capable of attracting a large number of people in a sustainable manner.

A New Species

The genus Acanthistius Gill, 1862 comprises ten putative valid species occurring in shallow warm-temperate waters of the Southern Hemisphere: South America (coasts of Ecuador, Peru, Chile, Brazil, and Argentina) southern Africa (Namibia and South Africa), southern Australia, New Zealand, Lord Howe, Norfolk, Kermadec and Easter, and Sala y Gómez islands. Two species: Acanthistius sebastoides (Castelnau, 1861) and Acanthistius sp are known from shallow waters of the east coast of South Africa (Heemstra and Randall, 1986). The latter taxon, previously known from a brief description of a single specimen, is here described from 23 specimens and named Acanthistius joanae. Acanthistius sebastoides is redescribed from 13 specimens and compared with A. joanae and species of Acanthistius known from South America and Australia. A neotype is designated for Serranus sebastoides Castelnau, 1861, as the two syntypes are apparently lost.

Subject Prospects for Africa's economies to end-2016. Significance The IMF's most recent forecast of 3% GDP growth for sub-Saharan Africa (SSA) in 2016 represents a significant cut from the 4.25% it expected in October 2015. This is a consequence of sharp slowdowns in the region's two largest economies, Nigeria and South Africa, droughts in previously buoyant economies (notably in eastern and southern Africa), a variety of idiosyncratic shocks and a prolonged commodity price downturn.

Coordination Conference

Two of the most significant regional organizations to emerge in Southern Africa in recent years are the Southern African Development Coordination Conference (SADCC), with nine members, and the Preferential Trade Area for Eastern and Southern Africa (PTA), comprised of fourteen states including five SADCC members. Although their purposes and programs are similar and steadily converging, SADCC and PTA exhibit distinct differences in their origins, memberships, institutional structures, financial patrons, ideologies, and strategies. Although national development remains the ultimate aim of both bodies, reducing external dependency, especially in the case of SADCC on South Africa, and regional cooperation are seen as essential to success. While obvious areas of conflict exist, the two organizations may be able to restrain their rivalry in the interests of their members and possibly of their own survival.

Background: Many alien plant species, such as Tithonia diversifolia, T. rotundifolia and T. tubaeformis, have been introduced to areas outside of their natural distribution range to provide benefits, but have subsequently become invasive, threatening biodiversity and agricultural productivity.Objectives: The aim of this study was to determine the current distribution and dates of introduction of invasive Tithonia species in eastern and southern Africa and to document the effects of T. diversifolia on rural livelihoods in Zambia.Method: Roadside surveys, and other sources of information, were used to determine the distribution of invasive Tithonia species in eastern and southern Africa. Household interviews were conducted to gauge perceptions and understand the impacts of T. diversifolia on local livelihoods in Zambia’s Copperbelt province.Results: Tithonia diversifolia is widespread in Uganda, Kenya, Tanzania, South Africa, Malawi and parts of Zambia but less so in Zimbabwe. Tithonia rotundifolia was comparatively uncommon in eastern Africa but common in some southern African countries, while T. tubaeformis was invasive in Swaziland, South Africa, Zambia and possibly also Zimbabwe. According to the majority of respondents in Zambia, T. diversifolia has negative impacts on native vegetation, mobility or access, water availability, crop yields and animal health.Conclusion: Invasive Tithonia species are widespread and spreading throughout much of Africa. Livelihood and biodiversity costs have not been considered by those actively promoting the use and further dissemination of T. diversifolia. We therefore recommend that detailed cost–benefit studies should be undertaken to support informed decisions on the future management of these species.

Gammiella ceylonensis (Broth. in Herzog) W.R.Buck & B.C.Tan is the only species of the genus in Africa. Clastobryella pusilla (Thér.) Wijk & Margad., recorded from Madagascar, the only member of the genus still recorded on the moss checklist for Africa, is a synonym of Gammiella ceylonensis. Clastobryella foliicola P.de la Varde is not a synonym of Gammiella ceylonensis but probably an Ectropothecium, thus removing the only west African record for Gammiella. An extension of range into South Africa is also noted, so Gammiella is now known from east and southern Africa and Madagascar.

Cattle have been known in northern East Africa for a long time. A single people initiated the spread of cattle farther south through southern East Africa, and partly into southern Africa, at a time prior to the expansion of Bantu-speakers into these regions. This spread was not accompanied by knowledge of milking. The milking of cattle, although very likely practised by some northern East African peoples since a very early period, diffused to Bantu peoples after their advance into eastern and southern Africa was well under way. The practice was probably borrowed from Southern Cushites first by Bantu in northern Tanganyika and through them transmitted to the rest of the eastern and southern Bantu.

Abstract A systematic review was conducted focusing on the distribution of Fasciola species and their snail intermediate hosts (IHs) in East and Southern Africa. The reviewed literature showed that both Fasciola hepatica and F. gigantica are present in East and Southern Africa, and infect a wide range of domestic and wild ruminants. Fasciola gigantica was reported in six East African and five Southern African countries, where Radix natalensis (found in low altitudes) was reported to be the main IH. Fasciola hepatica was reported in Tanzania and Ethiopia (East Africa), and in South Africa and Zimbabwe (Southern Africa), where Galba truncatula (found in high altitudes) was documented as the IH in all countries except in Zimbabwe. Both Fasciola species were documented in Tanzania, Ethiopia, Zimbabwe and South Africa. An overlap of the two was observed in areas with an intermediate altitude in Ethiopia and South Africa, where Pseudosuccinea columella was widespread and assumed to transmit both species. Pseudosuccinea columella has been reported in South Africa and Namibia, and proven to transmit F. gigantica in South Africa; its role in Namibia in the transmission of Fasciola species has not been reported. Other lymnaeid species such as R. rubiginosa were reported in South Africa, and R. auricularia in South Africa and Botswana; their role in the transmission of Fasciola species has not been proven. Future studies should aim to determine the role of P. columella in the geographical spread of the two species in East and Southern African countries.

Control And Management

AbstractWhile great progress has been made in the control and management of the HIV epidemic there is still much to be done. Using trends in the rate of new HIV infections in eastern and southern Africa we assess the current state of the epidemic and evaluate the future prospects for controlling it. If we let an incidence of 1 per 1,000 people represent a control threshold then this has been reached, or will probably be reached by 2020, in eastern Africa and is reachable by 2020 in those southern African countries that do not have particularly strong social and economic ties to South Africa if they continue to scale up their treatment programmes. In South Africa and its immediate neighbours Lesotho, Mozambique and Swaziland, the prospects are less certain. These countries are unlikely to reach the control threshold by 2020 but with sufficient political will and commitment to ‘treatment for all’ could do so by 2030.There are two important caveats. First, reaching the control threshold still leaves 35 thousand new infections a year. As the lessons of polio remind us, finding the last few, hard to reach cases will demand more focussed strategies. Second, ending AIDS will not end HIV and about 35 million people will have to be kept on ART for the next 30 to 40 years unless and until a cure is discovered. Even if we assume a modest cost of, say, US$100 per person per year for ART treatment and support, this corresponds to a continuing financial commitment of US$3.5 Bn per year although this is substantially less than the approximately US$ 40 Bn per year currently committed to HIV and AIDS.
