Tethered mobility and riparian resource exploitation among Neolithic hunters and herders in the Galana River basin,Kenyan coastal lowlands

Abstract

Human activity along the Galana River inside Tsavo National Park, Kenya extends from 6000 years BP until at least 1300 years BP. This time period in East Africa predates and includes the Pastoral Neolithic – geographically and temporally linked early cattle-herding cultures comprised of autonomous communities with loose cultural connections to one another. Data from some sites located in the Great Rift Valley, Lake Victoria Basin and Central Kenyan Highlands indicate that after 3000 years BP, residential mobility patterns increased and pastoralists adopted a strong dependence on maintaining and culling herds of domesticated animals. This pattern is not borne out in Tsavo, where artefact analyses indicate that people had restricted mobility and relied primarily on exploitation of an endoaquatic resource base. This study hypothesises that subdecadal periodicity in El Niño/Southern Oscillation index (ENSO) along with a general trend toward aridification of East African landscapes provided the environmental backdrop for a subsistence regime focused primarily within riparian environments of the Coastal Lowlands region.     

Holocene hyrax dung deposits in the afroalpine belt of the Bale Mountains (Ethiopia) and their palaeoclimatic implication

Abstract

The results of pollen analysis and radiocarbon dating are presented for two hyrax dung deposits from rock shelters found in the Afroalpine zone of the Bale Mountains (South-Central Ethiopia). Deposits accumulated from about 15,000 to 1500 (cal) years BP and from 7000 (cal) years BP till nowadays, respectively. Pollen spectra of the initial stages of deposit development (up to 15,000 (cal) years BP) correlate with unfavourable conditions in the Late Glacial Maximum. The African Humid Period (AHP) (15,000–5000 (cal) years BP) is registered in this palaeoecological record as well as the Younger Dryas event (about 12,500 (cal) years BP). Upward shift of Afromontane forest belt and expansion of ericoid communities at high altitudes were characteristic of the Pleistocene/Holocene transition (about 10,000 (cal) years BP). The AHP which continues around 10,000 (cal) years BP after Younger Dryas, was interrupted by a dry episode around 8200 (cal) years BP. Principal aridisation trend during the last 5000 years was observed. Presumably the first traces of human activities in this area can be shown for up about 2500 (cal) years BP.     

An Interview with Merrick Posnansky

Professor Merrick Posnansky has made numerous influential contributions to archaeology and African Studies during the last half century. Foremost among these is his holistic and inclusive archaeological initiatives that have developed informed representations of Africa and Africans in long-term historical perspective and in the present. He helped shape the early development of historical archaeology in Africa and African diaspora archaeology in the Atlantic world. Posnansky also developed university archaeology programs and reoriented museums in Uganda, West Africa, and the Americas, making them living institutions with a mandate to serve the public. He spent two decades in Africa, primarily in Uganda and Ghana, and later worked as Professor of Anthropology and History at UCLA and, for a period, directed the UCLA Center for African Studies. This interview outlines Posnansky’s life, career, and contributions to archaeology and African Studies across three continents. In addition, Posnansky reflects on contemporary archaeology and the discipline’s future prospects and challenges in Africa.     

J. Casely Hayford’s Social Imaginary of “Church Universal” in William Waddy Harris the West African Reformer: The Man and His Message (1915)

A close reading of J. Casely Hayford’s tract William Waddy Harris The West African Reformer: The Man and His Message (1915) provides insight into the political considerations accounted for in writing histories of world Christianity during the colonial period. Hayford centres Africa and William Waddé Harris in a social imaginary that critiques Europe as the exclusive centre of religious reform and renewal. I argue that Hayford employs methods of analysis, rhetorical devices, and literary interlocutors that reflect his African positionality within the early colonial period. To this end, I argue that Hayford’s tract reconceives a history of world Christianity that predates the organised study of missions, ecumenics, and world religions. Without dismissing the contributions of these fields to the emergent field of World Christianity, Hayford’s colonial positionality lends him a contrasting and precarious double consciousness with which to the re-imagine a discourse of universal Christianity through and out of West Africa.     

Public-making in a pandemic: The role of street art in East African countries

Street artists around the world have been prominent in depicting issues concerning COVID-19, but the role of street art in public-making during the pandemic is unexplored. Despite burgeoning street art scenes in many African countries since the early 2000s, African street art is relatively neglected in critical street art scholarship. In response, this paper examines street art created during the pandemic in East African countries, principally Uganda, Kenya, Rwanda, and Tanzania, and explores the ways in which it is engaged in highly distinctive forms of public-making. Drawing primarily on qualitative online interviews with East African artists creating street art, and image analysis using online search tools, the paper argues that street art in urban areas is attempting to create knowledgeable publics through countering disinformation about the pandemic, to responsiblize publics through public health messaging and, through community activism, to build resilient publics. The paper concludes that street art is potentially an important tool in tackling the COVID-19 pandemic in East African countries due to the proximity, and mutual constitution of, creative practices and publics, which emerge from the embedding of street art within the social spaces of cities and everyday experiences of the pandemic.     

Between Jakarta and Geneva: why Abbott needs to view Africa as a great opportunity

Australia's engagement with Africa during the Rudd and Gillard governments was primarily driven by the national interest, which revolved around three issues: humanitarianism, support for mining corporations, and the United Nations Security Council seat. This article argues that there is a need for the Abbott government to retain the same depth and breadth of relationships with Africa. It is in the interest of both Australia and African states for the Australian government to remain committed to humanitarian objectives and to help African countries meet some of their Millennium Development Goal targets. Moreover, the continued support of Australian mining corporations operating in Africa, especially through the training of African policy makers in mining governance, is good for both Africa and Australia. Finally, Australia's continued success in multilateral diplomacy will depend on support from all parts of the world, including Africa. Australia's success at the multilateral level will, in turn, result in bilateral benefits in other regions, including the Asia-Pacific.     

South Africa in world development: Prospects for a human economy (Respond to this article at http://www.therai.org.uk/at/debate)

South Africa was once notorious for an extreme system of racial inequality known as apartheid. It is still a world leader in economic inequality, but the racial situation is confused. In the meantime something like apartheid has become universal. The Southern African regional economy has some features that point to a more humane alternative to unequal society, to a “human economy”. The world needs a new free trade movement that would begin to dismantle the institutions of national privilege and insist on movement as a human right.     

Breeding for insect-resistant cotton across imperial networks, 1924-1950

This paper investigates the elevated expectations and dramatic downturns of the Empire Cotton Growing Corporation’s African experimentation program. It follows the trials of U.4, an insect-resistant variety bred to withstand continental growing conditions, whose expansion through east and southern Africa was filled with promise but ended in disappointment. My argument has two strands. First, U.4 was a product of imperial connections. It was an amalgam of breeding knowledge accumulated in India, specialized training received in Trinidad, and specimens imported from across the empire. Transnational scientific networks were crucial to the Corporation’s initial breeding successes. Second, the story that follows suggests that imperial scientific experts did not impose the Corporation’s research goals monolithically across a wide range of African environments. Rather, Corporation scientists recognized the diversity of African environments and adapted their breeding programs to match local agro-ecological realities. I suggest that the ECGC breeding program is a story of expert knowledge that incorporated rather than undermined ecological specificity.     

A 2500‐year record of marine resource use on Ulong Island,Republic of Palau

The paper reports fish bone and shellfish assemblages from Ulong Island in the Rock Islands of Palau, western Micronesia dating from ∼3100 to 500 BP . Use of marine resources in early prehistory appears to have been highly localised with increasing capture of outer‐reef/pelagic taxa including shark and tuna after 1000 BP . Local stocks of large Tridacnids were depleted during initial human use of Ulong Island, and there is a size decrease in Scarus sp. remains consistent with pressure on the inshore fishery, especially after establishment of permanent stonework villages in late prehistory. Comparison of archaeological assemblages of fish bone from other Rock Islands dated to after 2000 BP indicate that the captured fish species and major capture methods differ between sites and likely reflect local marine environments at each location.

Human corpse manipulation and the body as symbol: A case study from the Eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene

Human body manipulation and secondary burials are widespread funerary practices in many areas of the world. The archaeology of the Pampas and North-Eastern Patagonia, Argentina, is no exception. In this paper, archaeological case studies from the lower basin of the Colorado River during the Final Late Holocene (ca. 1000–250 years BP) are presented and discussed. Secondary burials were recovered that indicated an intentional manipulation of bodies. Evidences of cut marks and the coloring of bone surfaces were recorded. The bundles were composed of individuals of both sexes and diverse age categories. The Pampean region and North-Eastern Patagonia witnessed significant hunter–gatherer population dynamics during the last 1000 years BP. Climatic, ecologic, demographic, and economic explanations have been proposed as the background to these changes. In this paper, it is argued that accompanying these factors, as part of a broader socio-cultural scenario, were significant social interaction networks and processes of social complementarity between groups. In this context, it is proposed that the complexity observed in relation to the handling of bodies is part of a worldview in which the body was seen as material culture – as a symbol – that played an important role for the community in group identity maintenance in a cultural context undergoing significant organizational changes.     

A Review of Ceramics from Tanzania, Malawi, and Northern Mozambique, with Implications for Swahili Archaeology

Typological approaches to locally produced ceramics have played an important role in the archaeology of Eastern Africa. This paper engages with that history as it contextualizes the ceramic material recently recovered from the region around the site of Mikindani on the southern Tanzanian coast with known traditions from the Kenyan and Tanzanian coast, Malawi, and Mozambique. That comparison reveals the shifting connections and interregional relationships the inhabitants of the Mikindani region forged over the past two millennia with other communities in the Indian Ocean world and the African interior. Mikindani's ceramics are shown to provide important evidence of the deep connections between the region and the African interior to the southwest during the early second millennium, at the expense of connections with coastal Swahili sites further north. This pattern is unusual for a coastal site during the florescence of Swahili society and the typical expansion of Swahili involvement in the Indian Ocean world at that time. The typological comparison of the Mikindani material and other regional traditions thus allows us to consider the strengths and weaknesses of the typological enterprise, in terms of what information is brought to light and what information is obscured.     

“黑色大西洋”:近年来国外学界有关非洲在大西洋史中的地位与作用的研究

大西洋史研究主要关注15世纪末至19世纪上半叶欧洲、美洲与非洲之间的跨大西洋联系。自20世纪90年代以来,一些非洲史学家以及关注美洲与非洲之间历史联系的美洲史学家对以往大西洋史研究存在的“欧洲中心论”提出质疑,他们倡导“黑色大西洋”的概念。这些研究在强调大西洋世界形成过程对于非洲造成严重暴力与剥削的前提下,尤其关注非洲社会在跨大西洋联系形成过程中的能动作用。相关研究涉及非洲奴隶贸易与大西洋世界的形成、与非洲联系对美洲文明的影响、非洲裔美洲移民文化的起源、大西洋联系对于非洲社会的影响等重要论题。这些研究关注的是跨越殖民地或者民族国家地理范畴的历史动力,在很大程度上纠正了大西洋史研究中存在的严重缺陷,并且也极大地拓展了非洲史的研究领域,有助于深入认识非洲在世界历史进程中的贡献。     

‘Why Disgrace the Commonwealth?’ Ceylonese Communalism,the Search for Global Influence and the Politics of a Transnational Organisation, 1948–65

This article examines the progress of the commonwealth as a forum for political action by Ceylonese in the first two decades after the nation’s independence by focusing on the debate over Tamil political rights. Significantly, this domestic conflict intensified during a crucial phase in the commonwealth’s transition, from being essentially a members’ club consisting of Britain and the settler dominions to a multilateral organisation led by newly independent African and Asian states. In this ambivalent geopolitical landscape, an emerging small state such as Ceylon sought to use the commonwealth in such a way as to project itself on the world stage, while at the same time some of its citizens adopted the organisation as a focus for liberal causes against the state. In this way, it is argued, the ‘new commonwealth’ was being shaped by postcolonial British legacies of global influence and liberal politics.     

Africa's population and family planning dynamics

The historical and current demography of Africa in this discussion focuses on the context of population policy, contraceptive use, reproductive behavior, polygamy, and economic impacts. Sub-Saharan Africa countries have the highest rate of population growth in the world. 50% are aged under 20 years, and 20% are aged under five years. Urban areas are growing at the fastest rates in the world (5-6% annually). Population density remains low, except for areas where there is high soil fertility. Many African countries recognize the need for population policies. The most important donor to Africa, the World Bank, has pressured African governments to adopt family planning (FP) programs. A major World Bank study has shown that more FP services are desired by African women. Family expenditures for the 1980s for FP were estimated at $100 million annually, of which $53 million was provided by donors. Further expansion in the program is needed. The World Bank targeted contraceptive use at 25% of African married couples. Except for Egypt and North African countries, contraceptive use is around 3-4%. Another perspective on population reduction is to expand programs for child spacing and postnatal nutrition of mothers and infants. There has been a failure to turn health systems around to low-cost preventive health, particularly in rural areas. Infant mortality must be reduced before fertility will decline. Population growth can be slowed by changing the status of African women (high social status and recognition are associated with high fertility), age of marriage, child spacing, agricultural productivity, and nutrition. Demographic data on Africa have only become available during the past 25 years. African demographers are in short supply and require training abroad. Demographic data gaps and reliability problems are offset by the recent availability and quantity of survey data. Historical demography has produced conflicting results. Although some investigators, such as Ester Boserup, argue that population pressure results in agricultural innovations, Africa has yet to experience this phenomena. The youthful composition of the population guarantees continued population momentum. Fertility is enhanced by the cultural emphasis on perpetuating lineage and high fertility. Changes in reproductive behavior will depend on major social changes for women.     

利用K线图分析馆藏文物保存环境中温湿度研究

温度和相对湿度是馆藏文物保存环境监测的两项基本指标。为了更好地处理大量的温湿度监测数据,将K线理论引用至温湿度评估体系,通过K线图四要素的剥离和借鉴,定义采样周期内初始值对应开盘价、采样周期内结束值对应收盘价、采样周期内最高值对应最高价、采样周期内最低值对应最低价。结合一次临展的连续监测数据,使用K线图开展了展厅及部分展柜内温湿度评价,通过主动调湿和被动调湿的调控效果比对,为后续临展等短期展览调湿方式的选择提供参考依据。本工作为文物保存环境中温湿度的数据处理建立了环境监测数据分析模型,为文物保存环境质量评估提供了一种直观的探讨方案。     

The Arab Spring: A Fourth Wave of Democratization?

Between 1974 and 1990, over 30 countries in southern Europe, Latin America, some parts of Asia, Eastern Europe, and Africa made transitions to democracy, nearly doubling the number of democratic governments in the world. Samuel Huntington described this global shift as “Democracy's Third Wave” in an article published in 1991, which was later developed in a book titled The Third Wave: Democratization in the Late Twentieth Century. In these two works, he discusses the causes, features, and transition processes of the third wave of democracy and examines its prospects for sustainability and possible expansion in a nondemocratic world. He argues that the first and second democratic waves “were followed not merely by some backsliding but major reverse waves during which most regime changes throughout the world were from democracy to authoritarianism” (Huntington, 1991a). He also addresses the causative factors of this reverse wave in some countries, and he claims that the third wave of democratization that swept the world in the 1970s and 1980s might become a dominant feature of Middle Eastern and North African politics in the 1990s. The delay in this prophecy for two decades motivates us to question whether the Arab Spring is part of Huntington's third wave of democratization or a new fourth wave of democratization, or even a false start to democracy, as described by Larry Diamond ( 2011 ). The purpose of this article is to examine the causes, features, and transition processes of the Arab Spring in Tunisia, Egypt, Libya, and Yemen in correlation with Huntington's theorization on the third wave of democratization which, along with other available literature in the field, will be combined in a theoretical framework that will enable us to discuss the abovementioned elements of the Arab Spring through the lens of the third wave of democratization. Special attention is paid to the question of whether the Arab Spring falls into the framework of Huntington's theory, or whether it can be classified as a new fourth wave of democratization in countries that have unfavorable environments for democracy. The first part of this article highlights the causative factors that eased the emergence of the third wave of democratization in different parts of the world. The second part provides a historical overview of the major events of the Arab Spring in Tunisia, Egypt, Libya, and Yemen, while the third and fourth parts analyze the causes, features, and transition processes of the Arab Spring from Huntington's third wave perspective.     

The Origin of African Sheep: Archaeological and Genetic Perspectives

Indigenous African sheep genetic resources have been classified into two main groups, fat-tailed and thin-tailed sheep. The fat-tailed sheep are the most widely distributed, being found in a large part of North Africa (from Egypt to Algeria) and in Eastern and Southern Africa (from Eritrea to South Africa). The thin-tailed sheep are present mainly in Morocco, Sudan and in West Africa. African sheep were domesticated outside Africa. They share a common ancestry with European and Asian sheep. Archaeological information supports separate introductions and dispersion histories for the African thin-tailed and fat-tailed sheep. The first sheep entered Africa via the Isthmus of Suez and/or the southern Sinai Peninsula, between 7500 and 7000 BP. They were likely of the thin-tailed type. Fat-tailed sheep entered Africa through its northeastern part and the Horn of Africa. Mitochondrial DNA analysis supports a common maternal ancestral origin for all African sheep, while autosomal and Y chromosome DNA analysis indicates a distinct genetic history for African thin-tailed and sub-Saharan fat-tailed sheep. The main ancestral population of southern African fat-tailed sheep likely originated in East Africa. Further work is needed to assess the possible dispersion of sheep from western Africa to the southern African regions.     

Historical and Dialectical Perspectives on the Archaeology of Complexity in the Siin-Saalum (Senegal): Back to the Future?

Drawing on recent critiques of evolutionism, this article reviews the history of Iron Age studies in Siin-Saalum (Senegal) to examine the construction of African archaeological knowledge. From the 19th century to the 1980’s, analyses of complexity in Senegal have been animated by developmentalist views that have portrayed the regional past as a stagnant backwater. In the past 25 years, however, archaeological research has sought to redress these inaccuracies by exploring the diversity and idiosyncracy of African histories, and the processes behind sociopolitical change. These critical agendas can help us exploit the analytic potential of material culture to reincorporate African societies into the stream of world history, and to use the African past to reevaluate current scenarios of complexity and their applicability to various regions of the globe. To achieve these goals, however, and develop a fully self-reflexive archaeology in Senegal, researchers must eschew moral celebrations of African distinctness and strive instead to document how local pasts owe their particular qualities to complex political-economic articulations with other world societies. Concurrently, we must also attend to the dynamics of historical production in and out of guild circles, and consider our entanglement in the making of contemporary ‘culture wars.’ Because it is ideally suited to probe the historical and material depth of cultural differences and inequalities, archaeology must take a leading role in dispelling essentialist readings of Africa and promoting democratic knowledges about the continent.     

History and the Scientific Worldview

Worldviews affect human behavior, and how we behave affects the world around us. Animism and so-called higher religions remain influential worldviews; but the scientific worldview is comparably significant, and has undergone drastic change during the twentieth century. The physical science ideal of mathematical precision and predictability, as elaborated by Galileo, Newton, and their heirs, underwent an amazing transformation in the twentieth century when Big Bang cosmology substituted an expanding, unstable universe for the Newtonian world machine. As a result, a grand convergence of the sciences seems to be emerging around an evolutionary vision of how new aspects of reality emerge locally from new levels of complexity, like the heavier atoms, forged in stellar furnaces, the living molecules that arose in earth's primordial seas, and the symbolic systems invented by human societies perhaps as recently as forty thousand years ago. History, once a hopelessly inexact laggard among the sciences, might even become something of a model for other disciplines, since it deals with the most complex levels of reality we are aware of, that is, the world of agreed-upon meanings that guides our interaction with one another and with the biological, chemical, and physical worlds around us.     

Snapshots: Images of Men in the United States Colored Troops

Abstract

This article considers the intertwined impact of two very different developments that emerged during the era of the American Civil War. The first concerned the invention and dissemination of new photographic technology that made it possible for ordinary citizens to sit for portraits and come away with multiple copies of new cartes de visite. The second concerned the revolutionary decision by the federal government to recruit African American men into the Union Army. As a result, in the final two years of the war uniformed African American men were having their portraits taken, and those small images began circulating among friends and family members. This speculative essay considers how these small cultural artifacts might have reflected and shaped a world in transition.
