Four species of Poa L. are newly reported for sub-Saharan Africa and southern Africa, Poa compressa L., P. iconia Azn., P. infirma Kunth and P. nemoralis L. This is the first report of P. iconia from Africa. Vouchers at PRE of P. bulbosa L. all belong to var. vivipara Koeler, those of P. iconia belong to var. iconia and the one of P. trivialis L. belongs to var. trivialis. Two subspecies are recognised in P. pratensis L.: subsp. irrigata (Lindm.) H.Lindb. and subsp. pratensis. We also designate a lectotype for P. iconia and second-step lectotype for P. leptoclada Hochst. ex A.Rich. and report the first recording of a diclinous breeding system in P. binata Nees. Our account updates the treatment in Identification Guide to Southern African Grasses (Fish et al. 2015) including a key to the taxa and notes on infrageneric taxonomy, DNA subtypes, ecology, chromosome numbers and breeding systems.

Species Descriptions

Trisetopsis, a genus of temperate C3 grasses, extends from the Arabian Peninsula southwards along the African mountains (temperate Afromontane Region) to sub-Saharan Africa and Madagascar, with a centre of diversity in southern Africa. A taxonomic treatment of Trisetopsis in the Flora of southern Africa (FSA) region is presented. The proposed classification is based on existing and comparative evidence derived from macromorphology, micromorphology, leaf anatomy, DNA sequences and geographical distribution. Fourteen species of Trisetopsis are recognized in the FSA region, all of them endemic to the region. Five of the species are rare; based on IUCN Red List categories and criteria, three species are considered “Vulnerable”, one as “Endangered, and one as “Critically Endangered” and probably “Extinct”. Improved and emended species descriptions, a key to the species, updated distribution maps and illustrations, especially of the spikelets, are provided. Lectotypes are designated for the names Avenastrum longum var. grande and Avena longa (basionym of Trisetopsis longa).

SUMMARYThe zoonotic cestodeEchinococcus ortleppi(Lopez-Neyra and Soler Planas, 1943) is mainly transmitted between dogs and cattle. It occurs worldwide but is only found sporadically in most regions, with the notable exception of parts of southern Africa and South America. Its epidemiology is little understood and the extent of intraspecific variability is unknown. We have analysed in the present study the genetic diversity among 178E. ortleppiisolates from sub-Saharan Africa, Europe and South America using the complete mitochondrialcox1(1608 bp) andnad1(894 bp) DNA sequences. Genetic polymorphism within the loci revealed 15cox1and sixnad1haplotypes, respectively, and 20 haplotypes of the concatenated genes. Presence of most haplotypes was correlated to geographical regions, and only one haplotype had a wider spread in both eastern and southern Africa. Intraspecific microvariance was low in comparison withEchinococcus granulosussensu stricto, despite the wide geographic range of examined isolates. In addition, the various sub-populations showed only subtle deviation from neutrality and were mostly genetically differentiated. This is the first insight into the population genetics of the enigmatic cattle adaptedEchinococcus ortleppi. It, therefore, provides baseline data for biogeographical comparison amongE. ortleppiendemic regions and for tracing its translocation paths.

White Settlement

The relationships of the peoples of southern Africa after the establishment and expansion of the white settlement in the mid-seventeenth century can be seen in terms of both conflict and interdependence, both resistance and collaboration. The conflict often split over into warfare, not only between black and white, but also within both groups. As time passed, firearms came to be used by ever-widening circles of the combatants, often as much the result of the increased collaboration and interdependence between peoples as of the increased conflict. As Inez Sutton has pointed out, ‘in contrast to most of the rest of [sub-Saharan] Africa, the presence of a settler population ensured that the supply of arms was the most modern rather than the most obsolete’, and on the whole non-whites were acutely aware of changes in the manufacture of firearms in the nineteenth century.

The One

By way of conclusion, this chapter focusses on two issues. The first is how China’s relations with Sub-Saharan Africa (SSA) and Latin America and the Caribbean (LAC) are likely to be affected in the future by recent changes in the Chinese economy and its internationalization. Since 2012, the Chinese economy has been characterized by a ‘New Normal’ of slower economic growth and a rebalancing of the economy towards increased domestic consumption and less reliance on investment and exports. China also launched the One Belt, One Road (OBOR) initiative in 2013, which seeks to link China with other Asian countries and Europe through major investment projects. The second issue concerns the continuing tensions that derive from the asymmetric economic relations between China and the two regions and whether steps will be taken to resolve them.

There is need to re-examine the inclusion or exclusion of indigenous knowledge (IK) in the university curriculum in sub Saharan Africa (SSA). Western scientific knowledge on which the university curriculum in SSA is mainly based has proved to be inadequate in addressing developmental challenges. Using the curriculum of library and information science (LIS) departments in Anglophone east and southern Africa (AESA) as a case study, this chapter focuses on factors that influence the inclusion of IK in higher education in SSA. IK is recognised for its potential contribution to development by organisations such as the World Bank and African Union. Its inclusive ethos and accommodation of multiple realities also accounts for its popularity. In spite of that, IK has not established a stronghold in LIS curriculum in AESA. This study investigates the factors that influence its integration into the curriculum and makes recommendations based on the findings.

This article is a follow-up to that of Mr D. W. Phillipson published in this Journal in 1970, and to the six earlier lists compiled for the whole of sub-Saharan Africa by Dr B. M. Fagan. I have endeavoured to include here all radiocarbon dates for archaeological sites of the Iron Age and most of those of the end of the Stone Age in the eastern and southern part of Africa—that is from Ethiopia, the Upper Nile and the Congo Basin southward—which have been published or made available since the preparation of the former articles. Some of these dates are already included in recent numbers of the Journal Radiocarbon, or have been mentioned in publications elsewhere, as indicated in the footnotes. A large proportion of these new dates, however, have not yet been published, and are included here through the agreement of the various individual archaeologists and research bodies, all of whom I wish to thank for their cooperation. In particular, I am indebted to Mr David Phillipson for his willing assistance in providing a number of contacts and relaying information from southern Africa.

Biography in the African context can take many forms, from brief entries in a biographical dictionary or obituary in a newspaper to multivolume studies of single individuals. It can encompass one or many subjects and serves both to celebrate the famous and illuminate obscure lives. Biographies can be instructional as well as inspirational. Sometimes, it is hard to draw a line between biography and autobiography because of the way a work has been compiled. An attempt is made to understand this vast range of forms, with reference to social and political biography. The main focus is on work produced since the 1970s, with examples drawn from all regions of sub-Saharan Africa (although Southern Africa is better represented than others, as is English-medium material). Matters that preoccupy biographers everywhere, such as the relationship between writer and subject and the larger relationship between biography and history, are raised. Biography can be an excellent entry point into the complexities of African history.

Background: Regional trade could be a powerful engine of economic growth and sustainable job creation. However, South Africa’s exports to sub-Saharan Africa (SSA) are typically smaller and more short-lived than its exports to its traditional markets. This is despite South African policymakers considering trade with SSA to be a priority. Aim: The aim of the article is to evaluate South Africa’s utilisation of sustained export potential in SSA with a view to providing practical insights that will inform future policymaking and planning. Setting: Despite the priority attention given to SSA in the country’s trade policy, South Africa is yet to make meaningful inroads into SSA’s largest and fastest-growing economies. Method: The research method applied comprised three steps. The first step involved the identification, over a five-year period from 2010 to 2014, of consistently large and/or growing import demand in SSA for all products at the Harmonised System (HS) six-digit level, as well as the identification of products South Africa consistently exported competitively (sustainable exports). The second step entailed matching SSA markets with consistently large and/or growing import demand to South Africa’s sustainable exports. The third step involved evaluating South Africa’s utilisation of sustained export potential in SSA. Results: The results reveal that South Africa is utilising just over half (54%) of its sustained export potential in SSA. Conclusion: South Africa is, therefore, underutilising or not utilising close to 50% of its sustained export potential in SSA. Most of the export potential that South Africa is utilising is in Eastern Africa while most of the export potential that the country is underutilising and not utilising at all is in Central and Western Africa.

Complex Trajectories

Africa hosts the greatest human genetic diversity globally, but legacies of ancient population interactions and dispersals across the continent remain understudied. Here, we report genome-wide data from 20 ancient sub-Saharan African individuals, including the first reported ancient DNA from the DRC, Uganda, and Botswana. These data demonstrate the contraction of diverse, once contiguous hunter-gatherer populations, and suggest the resistance to interaction with incoming pastoralists of delayed-return foragers in aquatic environments. We refine models for the spread of food producers into eastern and southern Africa, demonstrating more complex trajectories of admixture than previously suggested. In Botswana, we show that Bantu ancestry post-dates admixture between pastoralists and foragers, suggesting an earlier spread of pastoralism than farming to southern Africa. Our findings demonstrate how processes of migration and admixture have markedly reshaped the genetic map of sub-Saharan Africa in the past few millennia and highlight the utility of combined archaeological and archaeogenetic approaches.
