An environmental history of Keate's Drift : the inter-relationship between humans and the environment over time.

Bowden, David Connor. January 1999 (has links)
This dissertation provides an exploratory study of the environmental history of the Keate' s Drift area, Umvoti Magisterial District, KwaZulu-Natal. The broad objectives are to explore the past and present modes of resource use of people living in the area, human reproduction, human consciousness and ecology from the Stone Age to the present day. Thereby we can deduce how, through the application of the techniques and methodology of environmental history, these findings can help establish baselines for understanding the problems facing environmentalists and policy makers in South Africa today. Such understanding can inform the formulation of more effective policies for the future. The study provides a history of how significant change at all levels of production, reproduction, consciousness and ecology initiated the first complete ecological revolution in KwaZulu-Natal between the Stone and Iron Age societies. Using the same methodological parameters, the dissertation then proposes that an incomplete ecological revolution has occurred in Keate's Drift since colonial times. It has found that the pre-colonial mode of resource use still exists in some form, but relies heavily upon migrant remittance money obtained from the modem industrial mode of resource use. The two modes of resource use operating together underlie the conflict between modernity and traditionalism in the Keate's Drift area. Interpretation of the historical evidence proposes that planners in charge of land redistribution in the Keate's Drift area must realise the role of the legacy of the past in development proposals. Planners must realise that the traditional mode of resource use exists alongside elements of the industrial mode. This is a situation resulting from the area's history, and any long term development plan that is going to work, needs to understand the historical legacy of the problems if they are to be resolved. / Thesis (M.Env.Dev.)-University of Natal, Pietermaritzburg, 1999.

An assessment of changes in land use/cover patterns in the Albert Falls area, KwaZulu-Natal, South Africa.

Yemane, Mehreteab Michael. January 2003 (has links)
The Albert Falls Area had witnessed severe competition over land use between agriculture, recreation, conservation and other land uses. The area also has been the scene for inefficient land management that led to degradation of land resources. For proper land use planning and environmental management, information on land use/cover change is vital. This study has developed a spatial and descriptive historical land use/cover databases for the years 1944, 1967, 1989, and 2000 to provide an understanding of land use/cover patterns in Albert Falls Area. The databases were created by interpreting historical aerial photographs and using Geographic Information Systems. The data was subsequently analyzed to detect relevant trends in land use/cover patterns in the study area. Generally land use/cover pattern of Albert Falls Area during the period 1944 to 2000 may be described as being mainly agricultural. The results showed a marginal increase of indigenous forests attributed to the continuous efforts by different governmental departments and policies that focused on the protection of the remaining patches of indigenous forests. Grassland not only decreased by more than half but it also deteriorated in quality during 1944 to 2000. Commercial Forestry predominates the study area and showed an increasing trend from 1944 to 1967. Cultivated Land was observed to decrease at the expense of Commercial Forestry plantations and Waterbodies. Although sugarcane plantations increased after 1967, total Cultivated Land showed a decreasing trend. The construction of Albert Falls Dam and other small Farm Ponds within the agricultural farms increased the land areas covered by Waterbodies. Residential Area coverage generally decreased irrespective of the encroachment of informal settlements, while that outside Non-Residential Area and Transportation Routes generally increased with the development of commercial agriculture in the area. Barren Land decreased continuously due to higher land demand in the study area. The study showed that land use/cover changes in Albert Falls Area. have resulted in habitat fragmentation, development of monoculture land use, flourishing of Farm Ponds in agricultural farms, and expansion of agricultural activities on marginal lands. Creation of corridors/linkages between the fragmented forest patches; commencement and implementation of the already well drafted land and land resource policies and regulations; commencement of the holistic management plans in the area were recommended for a sustainable land use. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2003.
