Effects of sedimentation on water-linked sectors in the Lusitu river catchment in southern Zambia.
type: CreativeWork
description: The problem of sedimentation and drying-up of rivers is very pronounced globally, continentally, and nationally. In Southern Zambia and, Lusitu River Catchment in particular, sedimentation and eventual drying up of the river during most parts of the year punctuated diverse environmental and socioeconomic problems, which this study investigated to contribute to the ongoing epistemic debates around the problem. Lusitu River supports a large population of over 20,000 Gwembe Tonga People who were relocated into Lusitu Catchment in 1958, following the construction of Kariba Dam. The overall aim of the study was to assess how sedimentation affected water-linked sectors in the Lusitu River Catchment to formulate strategies for mitigation of negative effects. The objectives of the study were to: (i) investigate main drivers of sedimentation in the Lusitu River; (ii) determine the magnitude of sedimentation in the downstream section of the Lusitu River; (iii) to assess how sedimentation of Lusitu River affected water-linked sectors and (iv) to design an integrated restorative framework for the Lusitu River Catchment. The study was informed by analytic eclecticism paradigm and used mixed methodology, particularly concurrent design so that where applicable, both quantitative and qualitative data were collected. Data on objective one was collected using observation and semistructured interviews and was analysed using descriptive statistics namely, mean, standard deviation, coefficient of variation and thematic analysis. Data on objective two was collected using sediment coring method and was analysed using Inverse Distance Weighted (IDW) in ArcGIS10.4. Data on objective three was collected using semi-structured interviews and was analysed using thematic analysis. Data on objective four was gathered using Focus Group Discussions and was analysed using thematic analysis. The results showed that agricultural activities particularly, dry season crop field preparation prior to the o…
