The Igbo-speaking people inhabit most of southeastern Nigeria. Their political economy and culture have been shaped by their long history of habitation in the forest region. Important themes relating to the Igbo past have centered on the question of origin, the agrarian bases of their economy, the decentralized and acephalous structure of their political organization, an achievement-based social system rooted in their traditional humane living, and a fluid gender ideology that recognized male and female roles as complementary rather than oppositional. The Igbo contributed to major historical developments including the development of agriculture, the Bantu migration, and its influence in the making of Bantu cultural areas in sub-Saharan Africa. On the global arena, the Igbo contributed significantly to the transformation of the New World through the Atlantic slave trade and the making of New World cultures. The Igbo made the transition to palm oil production in the postabolition era, thereby contributing to the industrialization of Europe as well as linking their society to the global capitalist economy from the 19th century. The Igbo encounter with Europeans continued through British colonialism, and their struggle to maintain their autonomy would shape British colonialism in Nigeria and beyond. The postcolonial era has been a time of crisis for the Igbo in Nigeria. They were involved in a civil war with Nigeria, known as the Nigeria-Biafra war, and experienced mass killing and genocide but continued to be resilient, drawing from their history and shared experience.

ABSTRACTRising competition and conflict over land in rural sub-Saharan Africa continues to attract the attention of researchers. Recent work has especially focused on land governance, post-conflict restructuring of tenure relations, and large-scale land acquisitions. A less researched topic as of late, though one deserving of greater consideration, pertains to how social differentiation on the local-level shapes relations to land, and how these processes are rooted in specific historical developments. Drawing on fieldwork conducted in Teso sub-region of eastern Uganda, this paper analyses three specific land conflicts and situates them within a broad historical trajectory. I show how each dispute illuminates changes in class relations in Teso since the early 1990s. I argue that this current period of socioeconomic transformation, which includes the formation of a more clearly defined sub-regional middle class and elite, constitutes the most prominent period of social differentiation in Teso since the early 20th century.

The supraspecific taxonomy of the species traditionally attributed to the flea beetle genusBlepharidaChevrolat, 1836 is discussed. A cladistic analysis, based on 30 morphological characters of traditionalBlepharidaspecies, has revealed that two genera occur in Sub-Saharan Africa:CalothecaHeyden, 1887 andBlepharidinaBechyné, 1968. The latter genus is known from Africa, and probably also Madagascar, and has two subgenera:Blepharidinas.str. andAfroblepharidasubgen. nov. Twenty-seven traditionalBlepharidaspecies are here attributed to the genusCalothecaHeyden, while eighteen species are assigned to the genusBlepharidinaBechyné. FourBlepharidinaspecies,antinorii(Chapuis, 1879),gedyei(Bryant, 1948),scripta(Weise, 1904) andsomaliensis(Bryant, 1948), belong to the new subgenusAfroblepharida. The following new synonymies are established:Eutheca conradsiWeise, 1906= Eutheca erlangeriWeise, 1907 syn. nov. =Blepharidella irregularisBryant, 1945 syn. nov.;Blepharida marginalisWeise, 1902 =Blepharida monticolaWeise, 1926 syn. nov. =Blepharida ugandaeBryant, 1944 syn. nov.;Blepharida inornataJacoby, 1895 =Blepharida semisulcataAchard, 1922 syn. nov.;Blepharidella lewiniWeise in Lewin, 1912 =Blepharidella picticollisBryant, 1945 syn. nov.;Podontia nigrotessellataBaly, 1865= Blepharidella rubrosignataBryant, 1945 syn. nov.= Blepharidella variabilisBryant, 1945 syn. nov.;Blepharida ornataBaly, 1881= Blepharida freyiBechyné, 1954 syn. nov.;Podontia reticulataBaly, 1865= Blepharida guttulaBryant, 1944 syn. nov.;Blepharida antinoriiChapuis, 1879 =Blepharida sudanicaBryant, 1944 syn. nov.;Blepharida scriptaWeise, 1904= Blepharida geminataBryant, 1944 syn. nov. In addition:Blepharida plagipennisAchard, 1922, its locality certainly mislabeled, is transferred to the New World genusNotozonaChevrolat, 1837;Calotheca thunbergiis proposed as the new name forBlepharida stolida(Thunberg, 1808). Finally, an updated catalogue of the known species ofCalothecaandBlepharidinais also supplied, including new synonymies, material examined, new faunistic records, distributions and chorotypes.

The net-spinning caddisfly genus Leptonema Guérin contains about 120 species, making it the largest genus in the subfamily Macronematinae (Hydropsychidae) and one of the most diverse in the order Trichoptera (Flint et al. 1987; Flint 2008). Most species are large, with wingspans of about 60 mm. They inhabit all types of running waters and generally comprise a significant proportion of invertebrate biomass in these waterways (Flint et al. 1987). In the New World, the genus is extremely diverse, with 106 species widely distributed from the southwestern United States to northern Chile and central Argentina, including the Antilles (Flint 2008). Another 18 species occur in sub-Saharan Africa and Madagascar (Munõz-Quesada 1997). Flint, McAlpine & Ross (1987) revised the whole genus, and also considered biogeographic and phylogenetic aspects. Brazil has 26 recorded species (Paprocki et al. 2004; Flint 2008).

Cassava root yields in three villages in southeastern Nigeria with marked differences in population pressure were related to soil properties using various models. The soils of the low population village, being formed from a different parent material, were more fertile than those of the medium and high population villages and cassava root yields were significantly higher in this village. The specific soil properties which appeared to promote cassava yields included pH and contents of Mn, silt and sand. Absolute values of exchangeable Mg, Ca, acidity and effective cation exchange capacity, although not significantly correlated with root yield, were also most favourable in the low population village. Thus inherent differences in soil properties rather than population pressure may be the major factors contributing to variations in cassava root yields in these villages.

This chapter traces the evolution of town planning, which developed in response to specific challenges of industrialization. However, the chapter is written from a Sub-Saharan standpoint, with emphasis on the planning situation in the context of the pre-colonial, colonial, and post-colonial periods. Although the arrival of European colonialists along the African coastline dates from 16th century, the colonial roots of modernist planning in Sub-Saharan Africa is traceable only to the 19th century. Post-independence, it has been recognized that the colonial planning systems are inadequate for effectively confronting the emergent development challenges such as rapid urbanization, informal settlements proliferation, as well as post-conflict and post-disaster situations. This chapter therefore highlights the efforts that have been made to reform urban planning processes in Sub-Saharan Africa, emphasizing the post-colonial discourse on urban and regional planning theories and practices that are responsive to prevailing circumstances within this sub-continent.

Rinderpest is one of the few diseases which have changed the course of world history. Originally an Asian disease, for centuries it had a devastating impact in Europe when introduced by returning and marauding armies accompanied by cattle as well as by cattle trade. Nowhere was its impact more dramatically expressed than in Africa where the sequel to its introduction into the Horn of Africa was a devastating panzootic throughout sub-Saharan Africa during the last decade of the 19th century extending into the 20th century. Massive deaths of livestock, wild animals and the people dependent on them led to widespread human misery and changed the face of the African continent forever.

Abstract Historical research is undeveloped concerning tourism in sub-Saharan Africa. This research contributes to scholarship about the history of tourism for climate and health. In South Africa the beginnings of international tourism are associated with its emergence as a health resort and to climate therapy. Using archival sources an analysis is undertaken of the factors that influenced the emergence of South Africa as a health destination during the 19th century. Climate therapy was of particular interest for the treatment of consumption or tuberculosis. Arguably, the perceived therapeutic regenerative qualities of South Africa's climate became a driver for the development of a form of international tourism that pre-dated the country's emergence as a leisure tourism destination.

African swine fever (ASF) is a highly infectious and fatal haemorrhagic disease of pigs that is caused by a complex DNA virus of the genus Asfivirus and Asfarviridae African suids family. The disease is among the most devastating pig diseases worldwide including Africa. Although the disease was first reported in the 19th century, it has continued to spread in Africa and other parts of the world. Globally, the rising demand for pork and concomitant increase in transboundary movements of pigs and pork products is likely to increase the risk of transmission and spread of ASF and pose a major challenge to the pig industry. Different genotypes of the ASF virus (ASFV) with varying virulence have been associated with different outbreaks in several countries in sub-Saharan Africa (SSA) and worldwide, and understanding genotype circulation will be important for ASF prevention and control strategies. ASFV genotypes unique to Africa have also been reported in SSA. This review briefly recounts the biology, genomics and genotyping of ASFV and provides an account of the different genotypes circulating in SSA. The review also highlights prevention, control and progress on vaccine development and identifies gaps in knowledge of ASFV genotype circulation in SSA that need to be addressed.
