Abstract
The conservation status of dambos, a particular type of wetland associated with the headwaters of rivers draining the central plateau area of Zimbabwe, is examined in terms of past and present utilisation and erosion problems. Pre- and post-1950 phases are recognized within both the commercial farming areas and the Communal Lands (or peasant farming areas). The pre-1950 phase on commercial farms was one of exploitation of dambos mainly for winter wheat production, such cultivation contributing towards locally serious erosion. Consequently legislation was passed to restrict disturbance of wetlands, especially for cultivation. The post-1950 phase on commercial farms was one of conservation, with minimal use of dambos for grazing and limited erosion. The pre-1950 phase within the Communal Lands, the former native reserves, was one involving progressive modification of the traditional farming system through, in particular, centralisation. Dambo cultivation, a well-established practice, continued throughout this place, but towards the end of this period there were localised signs of degradation associated, in part, with grazing. The post-1950 phase was one of increased pressure on land with a growing human and livestock population. Thus dambos were required to support more and more cattle throughout the year, whilst efforts to curtail dambo cultivation were not well-recieved by peasant farmers and may have compromised general conservation in the reserves.
