• Resumen

  • The Haubi Basin, situated in the Irangi Hills of Kondoa District, Dodoma Region, Tanzania (FIGURE 1), exhibits some of the most extreme examples of erosion and associated sedimentation in the region (Christiansson 1981; Payton et al. 1992) (FIGLIRE 2). The severity of the problem, with its consequent loss of productive land, has been known since the beginning of the 20th century (Kannenberg 1900; Obst 1915). Recognition of the extent and severity of the issues encouraged the British colonial government to introduce a variety of measures aimed at soil conservation in the 1930s (Fosbrooke 1950). These included the construction of check-dams, contour bunds and contour planting with sisal. After independence, a second programme of soil conservation measures was launched. These were initially similar to those employed under colonialism, but later included de-stocking, resulting in the removal of some 90,000 livestock from the most severely eroded areas. As in the colonial period, recent overexploitation of land resources by local populations was regarded as the primary explanation for the continuing soil erosion.
