This study was a comparative study to generate information which may be useful in the<br />

analysis of causes and mitigation measures of landslides throughout the country. As<br />

shown in Section 1.1, previous landslide studies concentrated on landslides in Southern<br />

Malawi. It was imperative to study landslides in Northern and Central Malawi,<br />

considering the variations in climate and physiography of Malawi (Linceham, 1972; and<br />

Agnew and Stubbs, 1972).<br />

In the study areas, landslides either claimed human lives or damaged property, or<br />

infrastructure. Continued instability put human life and property in great danger. There<br />

was, therefore, an urgent need to investigate the causes of the landslides in order to<br />

formulate an informed basis for minimising or preventing further losses. Through the<br />

identification of the causes, the study would form the basis of landslide hazard<br />

management for the study areas.<br />

In Malawi, this research is the first comparison of landslide occurrences and a follow-up<br />

attempt to classify the events. The research was also based on a simple methodology<br />

developed and modified for a developing country. This methodology could form the<br />

basis for teaching slope stability problems at tertiary level in Malawi as one way that<br />

makes the study of practical use.<br />

According to the available international literature, the research is the first of its kind to<br />

incorporate traditional knowledge and beliefs in the understanding of landslides. It is<br />

also the first attempt to assess gendered perceptions towards landslides in Malawi. In<br />

that respect, the research is an important step towards the incorporation of traditional<br />

knowledge into the scientific understanding of landslide mechanisms of generation<br />

while bearing in mind gender-based perceptions. This would bring a better<br />

understanding of the complex relationship between humans, the physical environment,<br />

and the occurrence of landslides.<br />

1.5 Significance of the Study<br />

The study is significant in a number of ways. Firstly, the study has generated information<br />

on landslide occurrences which will be used for comparative purposes. The study also<br />

fills in critical gap since landslide studies have been concentrated in Southern Malawi<br />

and very little work has been done in Northern and Central Malawi (Msilimba, 2002; and<br />
