Abstract:In recent years, several attempts to revitalize Area Studies have concentrated on oceans as the unifying force to create regions. In this respect, the Indian Ocean has become a prime example to show how economic as well as cultural flows across the sea have contributed to close connections between its shores. However, by doing so, they not only seem to create a certain, rather homogeneous, Indian Ocean space, they often also lead to a conceptual separation between “coast” and “hinterland,” similar to earlier distinctions between “African/Arab” or “East/Central Africa.” In this contribution, so-called “Arab” traders who settled along trade routes connecting the East African coast to its hinterland will serve as an empirical ground to explore and challenge these boundaries. Tracing maritime imaginaries and related materialities in the Tanzanian interior, it will reflect on the ends of the Indian Ocean and the nature of such maritime conceptualizations of space more generally. By taking the relational thinking that lies at the ground of maritimity inland, it wishes to encourage a re-conceptualization of areas that not only replaces a terrestrial spatial entity with a maritime one, but that genuinely breaks with such “container-thinking” and, instead, foregrounds the meandering, fluid character of regions and their complex and highly dynamic entanglements.

The Impact

Timing and magnitude of surface uplift are key to understanding the impact of crustal deformation and topographic growth on atmospheric circulation, environmental conditions, and surface processes. Uplift of the East African Plateau is linked to mantle processes, but paleoaltimetry data are too scarce to constrain plateau evolution and subsequent vertical motions associated with rifting. Here, we assess the paleotopographic implications of a beaked whale fossil (Ziphiidae) from the Turkana region of Kenya found 740 km inland from the present-day coastline of the Indian Ocean at an elevation of 620 m. The specimen is ∼17 My old and represents the oldest derived beaked whale known, consistent with molecular estimates of the emergence of modern strap-toothed whales (Mesoplodon). The whale traveled from the Indian Ocean inland along an eastward-directed drainage system controlled by the Cretaceous Anza Graben and was stranded slightly above sea level. Surface uplift from near sea level coincides with paleoclimatic change from a humid environment to highly variable and much drier conditions, which altered biotic communities and drove evolution in east Africa, including that of primates.

ABSTRACTThe emergence of the Indian Ocean region as an important geo-political arena is being studied across a range of disciplines. Yet while the Indian Ocean has figured in Swahili studies and analyses of East and Southern African diasporic communities, it has remained outside the mainstream of African Studies. This introduction provides an overview of emerging trends in the rich field of Indian Ocean studies and draws out their implications for scholars of Africa. The focus of the articles is on one strand in the study of the Indian Ocean, namely the role of print and visual culture in constituting public spheres and nationalisms in, across and between the societies around the Ocean.The themes addressed unfold between Southern and East Africa and India as well as along the African coast from KwaZulu-Natal through Zanzibar and Tanzania to the Arab world. This introduction surveys debates on print culture, newspapers and nationalism in African Studies and demonstrates how the articles in the volume support and extend these areas of study. It draws out the broader implications of these debates for the historiographies of East African studies, Southern African studies, debates on Indian nationalism and Islam.

The aim of this paper is to illustrate the role of Chinese ceramics in Swahili society, with particular emphasis on their funerary uses. Although the importance of Chinese ceramics, especially porcelain, is attested throughout the Indian Ocean, scholars have only recently pointed out their role not only as chronological markers, but also as useful tools to better understand the politics and social customs of certain areas, such as the East African Coast. Imported vessels are involved in several ritual activities which have been performed in Swahili houses since ancient times. Ceramics act as protective tools in the innermost and main section of the house, exclusively reserved for women. According to local customs, Chinese ceramics are believed to be able to ward off negative influences. Furthermore, ceramics became part of the constitution of authority and power, not just a reflection of them. In particular, their importance is evident from their use in religious monuments such as mosques and tombs, where they are used as architectural decorative elements in order to display the wealth of the deceased and as symbols of legitimacy bestowed from ancestors to their heirs. Chinese porcelain in funerary contexts thus became a necessary instrument whereby the Swahili elite asserted their prominence during the continuous negotiation of power between them and other social classes.

The Relationship

Knowledge of the processes that control East African rainfall is essential for the development of seasonal forecasting systems, which may mitigate the effects of flood and drought. This study uses observational data to unravel the relationship between the Indian Ocean Dipole (IOD), the El Niño Southern Oscillation (ENSO) and rainy autumns in East Africa. Analysis of sea–surface temperature data shows that strong East African rainfall is associated with warming in the Pacific and Western Indian Oceans and cooling in the Eastern Indian Ocean. The resemblance of this pattern to that which develops during IOD events implies a link between the IOD and strong East African rainfall. Further investigation suggests that the observed teleconnection between East African rainfall and ENSO is a manifestation of a link between ENSO and the IOD.

Mean State

The role of the Indian Ocean dipole (IOD) in controlling interannual variability in the East African short rains, from October to December, is examined in state-of-the-art models and in detail in one particular climate model. In observations, a wet short-rainy season is associated with the positive phase of the IOD and anomalous easterly low-level flow across the equatorial Indian Ocean. A model’s ability to capture the teleconnection to the positive IOD is closely related to its representation of the mean state. During the short-rains season, the observed low-level wind in the equatorial Indian Ocean is westerly. However, half of the models analyzed exhibit mean-state easterlies across the entire basin. Specifically, those models that exhibit mean-state low-level equatorial easterlies in the Indian Ocean, rather than the observed westerlies, are unable to capture the latitudinal structure of moisture advection into East Africa during a positive IOD. Furthermore, the associated anomalous easterly surface wind stress causes upwelling in the eastern Indian Ocean. This upwelling draws up cool subsurface waters, enhancing the zonal sea surface temperature gradient between west and east and strengthening the positive IOD pattern, further amplifying the easterly wind stress. This positive Bjerknes coupled feedback is stronger in easterly mean-state models, resulting in a wetter East African short-rain precipitation bias in those models.
