Historical Perspectives on Pre-Colonial Irrigation in Southern Africa

Abstract

One of the basic areas of interaction between water as natural resource and human societies as agents of cultural transformation is the technology of irrigation. In Africa at least 66 per cent of the available water is used for purposes of irrigation. For more than 4 000 years irrigation has secured food supplies for humans on a continent that is noted for its relative shortage of sufficient natural water supplies.

There is a remarkable hidden power of water in the history of southern Africa. This is particularly the case when we consider the development of early irrigation technologies of Iron Age farmers. The small irrigation furrow of the subsistence farmer was just as important to an insular community of Bantu-speaking people in pre-colonial times, as is the sophisticated irrigation technology in present-day South Africa. Currently there is a paucity of information about pre-colonial indigenous irrigation technology. This can be ascribed to a number of factors of which the invasion of modern Western traditions in the nineteenth century is perhaps the most important. A number of other factors for the apparent blind-spot is also presented in this study.

In southern Africa there are traces of indigenous pre-colonial irrigation works at sites such as Nyanga in Zimbabwe; the Limpopo River Valley; Mpumalanga; and South Africa's eastern Highveld. Reference is also made in this article to specific strategies of irrigation used by Iron Age communities, prior to the advent of a colonial presence. Finally, attention is also drawn to pre-colonial land tenure and state formation against the backdrop of Wittfogel's theories on hydraulic society.

Is technology the enemy of culture?

This article examines how changes in technology affect the strategies various national governments have adopted to protect their respective cultures. The focus is primarily on national policies toward film and television. National quota systems that limit the import of American entertainment products will soon be made impossible to enforce, thanks to new digital and satellite technologies. Economic incentives will still make American products attractive to proliferating private television channels, but narrow‐casting and cable distribution will offer new opportunities for locally produced shows and movies. Increasingly, those countries that wish to continue to protect their cultures from the homogenizing trends of global markets dominated by American films and television programs, will need to move away from quotas and toward subsidies. Moreover, they will have an interest in promoting technologies that are favorable to the promotion of national culture. Financial instruments that reduce risk to local producers may also be appropriate.     

Comments on archaeology into the 1990s

This article focuses on the complexity of Early Bronze Age weapon depositions. While some of the deposited weapons have been disabled by intentional breakage, others seem to be more or less unused. A plausible explanation for the variability is that the surrender of lethal weapons to land or water was a means of coping with their power or agency – their individuality. We suggest that weapons, in their capacity as extensions of warriors’ bodies, may have substituted for humans in ritual depositions. The metalworkers also come into play, due to their capacities in the processes of making weapons and shaping weapon technologies. Although we consider the three depositions that we discuss to relate to rituals on the occasion of warfare, we are not aiming for a uniform explanation. In the same way as the patterned human behaviour of a ritual is a means of subsuming individual events into a greater order, so a focus on general patterns may subsume the complexity of the past by ignoring the many different events leading to, e.g., the deposition of metalwork. Far from seeing these perspectives as contradictory, we try to use three well-documented individual cases to shed light on the variability within the pattern.     

WikiLeaks,Anarchism and Technologies of Dissent

Abstract: WikiLeaks is a controversial organisation that attracts polarised responses. This is not unexpected given its key objective of exposing the secrets and social control ambitions of the powerful. While its supporters laud its pursuit of an informational commons, its detractors condemn its antisocial character, its megalomania—and its anarchism. It is the latter that particularly interests us here. This paper treats the “charge” of anarchism seriously, however, giving it the analytical attention it warrants. It does this by first identifying those characteristics of the organisation that would render it anarchist, and then to conceptualise what this anarchism means. It highlights two important elements of the WikiLeaks story: the anarchical character of the technologies it utilises to foment its dissent; and the anarchical ethos of the organisation's radical politics. We conclude by also considering the tensions and contradictions in WikiLeaks that temper both its anarchism and its social change objectives.     

Trees as technology: planting shelterbelts on the Great Plains

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.     

The emergence of Baltic Moorkultur: visions of scientific-technological mastery of peatlands in the age of great social change, 1850–1914

ABSTRACT

This article looks at the imaginaries of progress through technology and new activities by tracing the emergence of Baltic Moorkultur in Estonia and Livonia from the 1850s to the early 1910s. Baltic Moorkultur, a set of modern drainage and peat extraction techniques, has been viewed as part of a modernisation process and evolving visions of future, which touched the identity of Baltic German landowners, scientists and entrepreneurs. General reasons for an impetus for the large-scale reclamation of peatlands were the growth of population, economic liberalisation, growing demand for fuels and the fact that the basis of manorial economy gradually crumbled and led to increasing urge to modernise its source of livelihood. Baltic Moorkultur can be thought as a high-tech response of that time to the exploitation of peatlands. This article explains why it became adopted and how it altered the appraisal of environments that had been perceived as suboptimal.     

Science,industry and the colonial state: a shift from a German- to a Dutch-controlled cinchona and quinine cartel (1880–1920)

This study shows how control over delicately balanced supply chains from raw material to the final product shifted from one national industry to another. By 1920, Dutch cinchona producers and quinine manufacturers dominated the international cartel that controlled the worldwide production and distribution of quinine (an antimalarial), quinine sulphate (a semi-finished product) and cinchona (the raw material). Twenty years earlier, however, this cartel had been controlled by the German pharmaceutical industry. How can we understand the shift of power in the world’s first pharmaceutical cartel? We argue that the internal shift of power was largely the result of the following three factors: a global industrial laboratory revolution; the vertical integration of a transoceanic network of cinchona producers, quinine manufacturers, (colonial) scientists and state officials across the Dutch Empire; and Germany’s economic isolation during the First World War.     

The Extreme Right in Interwar France: The Faisceau and the Croix de Feu

While most discussions of the international efforts at post-war exploitation of German science and technology by the Allied occupation powers assume similar methods and aims across the nations involved, the French case diverges in important ways because of a fundamentally different understanding of technology transfer. The Americans and British hoped to enlist the French in exploitation programmes similar to their own, and to an extent succeeded, but persistent distrust of French motives largely prevented this co-operation from forging similarities beyond the surface level. French policy-makers’ alternate conception of science and technology as socially embedded led to very different strategies for exploiting German advances, and despite post-war antagonism, led to Franco-German research collaboration that would prove valuable building relationships between these nations.     

Technology and Global Politics: The Modern Experiences of Bertrand Russell and John H. Herz

As questions of technology and world government are returning to the agenda of International Relations (IR), there is a risk that technology is approached in a simple, instrumentalist manner. Beginning from an overview of the overwhelmingly instrumental approaches to technology lodged in the dominant traditions of IR, the article revisits the post-war decades when scholars thought profoundly about the impact of technology on global politics. Combining the history of (international) political thought, IR theory, and Science and Technology Studies (STS) the article examines the relationship between technology and politics, authority, and liberty in the thought of Bertrand Russell (1872–1970) and John H. Herz (1908–2005), which leads to the unearthing of a sophisticated and complex set of ideas. Particularly during the nuclear revolution, these figures developed global visions in which the interrelations among technology, security, democracy, sustainability, and freedom were critical. Russell and Herz's approaches to technology and (global) politics are insightful and relevant for IR's attempt to re-engage with technology: by anticipating contemporary critical and reflexive approaches to technology, they can help bridge the fields of IR and STS and open new avenues for research. The Large Technical Systems (LTS) approach within STS is used to exemplify this possibility.
