MENVSC (Geography) === Department of Geography and Geo-Information Sciences === The Limpopo lowveld is at risk of floods from tropical storms from the South West Indian Ocean. The flood risk is particularly high in low altitude areas with poor infrastructure and limited resources. This study assessed flood vulnerability and adaptation at Lenyenye, Ga-Kgapane Masakaneng and Nkowankowa Section B and C within the Mopani District in the Limpopo Province of South Africa. The research objectives were to establish the determinants of flood vulnerability, assess the levels of flood vulnerability and the community‟s coping strategies. A quantitative survey approach was employed using questionnaires which were administered to affected households to identify determinants of flood vulnerability, indicators and coping strategies by communities. A qualitative survey was also undertaken to supplement the information obtained from the quantitative survey. Key informant interviews were conducted with disaster management authorities in the study area to provide information on indicators, flood experience, adaptation and mitigation measures. Field observations were undertaken to observe the physical landscape and flood impacts. Secondary data were acquired through records, maps, Census 2011 and from the South African Weather Service. Collected data were imputed into the flood vulnerability index to measure the level of flood vulnerability. The results of this study will contribute to flood disaster risk reduction in the lowveld. The results indicate that flood vulnerability in the study areas is determined by dwelling quality, poor or lack of drainage, education levels, employment status, rainfall amount and topography. The calculated flood vulnerability levels in the three case study villages indicate that Ga-Kgapane Masakaneng, Lenyenye and Nkowankowa Section B and C have a „vulnerability to floods‟ level. However, the FVI also showed that the economic aspect scored a high vulnerability to floods in Ga-Kgapane. In Nkowankowa Section B and C; physical component obtained a „high vulnerability to floods.‟ Major coping strategies in the three case villages were: making „Le-guba‟ around houses; sand-bags; making a furrow and channel around houses and on roads; temporary relocation and lastly relocating to a safer area. Key recommendations are public awareness; integrating modern mitigations with local knowledge; development of programs to ensure resilience through incorporation of (Integrated Development Planning) IDP and flood management and flood early warning system.
