Introduction: Failed Futures? (Post)-Colonial Planning And Future-Making In Tanzania, Ulrike Lindner

Zamani: A Journal of African Historical Studies

Future-making and planning as social practices are strongly related to the
surrounding society’s political structures and power relations. In this
special issue of ZAMANI, we conceptualize future-making as physical
changes and social practices that shape future conditions by making future
an issue in the present. We analyse how different approaches to the future,
and also surprises and unintended side-effects, have informed the politics
and practices of planning in Tanzania and its various regions.1 When we ask:
“Failed Futures?” we address future in the plural, a term that has diffused
into historical scholarship rather recently and originates from
futurology/future studies, known …


‘Sold Down The River’: Histories Of Production, Trade, And Transport Along The Waterways Of The Kilombero Valley, Tanzania, Jonathan M. Jackson Dec 2024

‘Sold Down The River’: Histories Of Production, Trade, And Transport Along The Waterways Of The Kilombero Valley, Tanzania, Jonathan M. Jackson

Zamani: A Journal of African Historical Studies

This article considers the centrality of waterways in the Kilombero Valley of Tanzania to the region’s histories of development from above, particularly in terms of infrastructure, crop production, trade, and transport. Early colonial investigations hoped Kilombero’s riverine system might prove a navigable link from the coast to the Southern Highlands. The British colonial era instead focused more on utilising riverine networks for internal goods transport. Throughout these colonial visions – simultaneously ambitious and naïve – the prevalent dug- out canoe was considered unsafe, inefficient, and replaceable by modernised methods. But the canoe – a symbol of indigenous knowledge and practice …
