Furrows in Africa — canals in the Americas?

In: Azania. - 0067-270X .- 1945-5534. ; 49:4, s. 524-529

Journal article (peer-reviewed)abstract
- This brief comment argues that the use of the term furrow system for locally developed irrigation in Eastern Africa is misleading in an international comparative perspective. It is at odds with the terminology in irrigation engineering and also with the archaeological terminology used outside Eastern Africa. Internationally, the term canal is used for the artificial watercourses that bring water from the source to the field, while furrow irrigation refers to one specific way of applying water to the individual field.

Introduction: Historical and Regional Perspectives on Landscape Transformations in Northeastern Tanzania, 1850-2000
- 2008
-
In: International Journal of African Historical Studies. - Boston : African Studies Centre. - 0361-7882 .- 2326-3016. ; 41:3, s. 369-382
-
Journal article (peer-reviewed)abstract
- The article focuses on the historical and regional views on landscape shift in northeastern Tanzania from 1850-2000. It highlights several perspectives on the impact of landscape transformation towards the social relation in the northeastern part of the country. Specifically, it discusses how regional historical method to land cover changes offers an analytical field to bridge social gap. It primarily considers the perspectives of a group of scholars, centering on their views on human-environmental relationships and political economy. In addition, it explores the history and spatial interactions in the region, regarding as well the economic determinants of land use.

Islands of intensive agriculture in African drylands : towards an explanatory framework
- 2000

In: The archaeology of drylands. - London : Routledge. - 0415230012 ; , s. 252-267

Book chapter (other academic/artistic)abstract
- The social and cultural diversity of populations in dryland Africa is vast, with population densities ranging from less than five to more than 300 per square kilometre. As Mortimore (1998: 17) has emphasized, this range in population densities cannot be explained by differences in climate:'there is a weak relation between aridity and population density. While high densities are rare in the arid zone, the higher ones are found not in the moist, but in the dry semi-arid zone.'It is evident that the distribution of different farming systems, especially in the semi-arid lands, reflects social, economic and political factors at least as much as environmental factors. The farming systems developed for coping with arid lands are thus many and varied and are the result of centuries and millennia of agricultural experience. No single formula for cultivating arid lands can be found-each farming system relies on its own mix of components to cope with the two main problems of farming drylands: water management and fertility maintenance. This is achieved through crop varieties, meticulous time-scheduling of planting, farming practices aimed at restoring organic content, and construction works such as terraces, irrigation furrows and so on. Furthermore, interactions with pastoralism seem to be a sine qua non of agrarian societies in drylands. The ways in which these different components are combined vary throughout eastern and southern Africa, although the regional distribution of farming systems in the area is only vaguely known and documented (Ker, 1995). Temporary cultivation with little investment in land is often assumed to be the general rule, but several exceptions …

Islands of intensive agriculture in Eastern Africa: past & present
- 2004
-
Book (peer-reviewed)abstract
- Islands of intensive agriculture are areas of local cultivation surrounded by low-density livestock herders or extensive cultivators. Along the line of the East Africa Rift Valley, and in the highlands on either side, communities of considerable historical depth have developed highly specialized agricultural regimes, employing such labor-intensive devices as furrow irrigation, hillside terracing, and stall-feeding of cattle.This collection continues the advance in the understanding of African agricultural practices through the combination of geographical, ethnographic, and archaeological research, concentrating on actual fields, farming strategies, and cultivation techniques.
