Abstract
Due to its geographical location, poor economic situation and geological features that are characterised by mostly mountainous terrain, Lesotho is vulnerable to hazardous events associated with climate, such as drought, floods, heavy snow, and severe frost. This research explores factors underlying spatial vulnerability of places to natural hazards in south-western Lesotho. Prior vulnerability assessments in Lesotho have investigated vulnerability in terms of identifying populations that are most food insecure and vulnerable to hunger. By broadening the scope of vulnerability to include biophysical and socioeconomic characteristics, the study emphasises the concept of place vulnerability as a foundation for understanding Lesotho’s vulnerability to natural hazards. Spatial orientation of vulnerability within a geographical area provides an easy way for planners and decision makers to identify areas that may require additional resources in order to prepare for disasters. To date, no quantitatively based vulnerability assessment has been undertaken in Lesotho, so this study is one of the first to assess place vulnerability to natural hazards in Lesotho using GIS and it emphasise the role of geography of a place.
