A Case Study of the Nilgiri District in Tamil Nadu, India, Examining How the Tribal Population Perceives the Risk of Landslides
摘要
The schedule tribe was segregated physically, socially, economically and even culturally in the Nilgiri district compared to the rest of the population. Most of the tribal residents are living in a region that is very prone to landslides. Thus, the perception of landslip hazard and susceptibility in people is an important subject to be studied. In this chapter, the focus was about the risk of landslides as perceived by tribal people. Perception of risk is also very important when attempting to come up with systems, practises and policies to cushion the locals. This is more so when mitigation strategies that are used to deal with risks are not structural in nature as is the case with non-structural measures such as relocation and early warning systems that accommodate the involvement of the involved community. The study was analysed on the primary data, which was collected with the help of a 400 person sample size pre-defined questionnaire. The survey targets the native community who are above 18 years. Independent sample t-test, analysis of variance, statistical analysis of frequency and ultimately development of regression model was used in the study. Judging by the results of the research, the results suggest that tribal communities believe the risk of landslides is quite high, especially with respect to the occurrence of landslide (M = 2.124) and feel safe (M = 2.11) variables. Conversely, the variable of affects quality of life had a lower score (M = 1.459), which shows that the concern was less in that dimension. Since 88% of the variables were above the average score, it indicates that there is increased perception of risk. The overall mean score of 15.476 or 57.33 indicates that most of the respondents are at moderate to high-risk level and this warrants the application of special awareness and mitigation measures.
