Islands of Intensive Agriculture in Eastern Africa: Past & PresentMats Widgren, John Edward Giles Sutton British Institute in Eastern Africa, 2004 - 160 sidor This book reveals complex agricultural methods and dynamic farming strategies which evolved long before colonial intervention or recent development projects. These indigenous systems created spectacular landscapes, with terrace walls to conserve the soil and hill-furrow irrigation to supplement low or seasonal rainfall, thus allowing intensive exploitation of all usable land. Mulch or animal manure were applied to boost fertility on regularly planted fields. Labour, communal tasks and the allocation of land and water required social organization and the use of sanctions. The studies examine 'islands' where intensive devices and integrated systems have been developed and maintained. Sometimes they are in relatively isolated and arid localities but are able to support surprising concentrations of population. These islands of intensive local cultivation are surrounded by a low-density 'sea' of livestock-herders or extensive cultivators. Examples of islands in the Eastern Rift Valley and flanking highlands -- Iraqw in Tanzania, Marakwet in Kenya and Konso in Ethiopia -- are provided by geographers and anthropologists applying an historical perspective. The archaeological example is of Engaruka in a dry stretch of the Rift in northern Tanzania where a cluster of nucleated villages with skilfully engineered irrigation thrived between the fifteenth and seventeenth centuries. Geographers, climatologists, ecologists, anthropologists, historians and archaeologists have brought together their skills to provide lessons for modern development. Book jacket. |
