• In component 2, 24 % of variation is explained by 2 variables, namely, % of
NSA to total geographical area and number of tractors/1000 ha area sown.
• In component 3, 22 % of variation is explained by 2 variables, i.e. % of fallow
land to total geographical area, and agricultural cooperative societies/lakh
population.
8 Socio-economic Vulnerability Index for the Districts
of Karnataka
For development of the socio-economic vulnerability index, 10 important indicators
described in Table 3 were considered. As agriculture is a dominant livelihood
activity, a few agricultural indicators have also been included in the development of
this index.
In Table 7 rank 1 indicates maximum vulnerable district and vulnerability
decreases with increasing rank. PCA shows that Yadgiri, Chitradurg, Raichur,
Chamrajnagar and Chikkaballapura are the top five socio-economically vulnerable
districts. Bangalore (U), Dakshin Kannada, Udupi, Dharwad and Uttara Kannada
are the least socio-economically vulnerable districts of Karnataka. Figure 18 depicts
the socio-economically vulnerable districts of Karnataka, with red and green
coloured areas representing most and least vulnerable districts, respectively.
Table 9 gives the details of significance of variables that explain variation in each
component.
• The rotated factor analysis generated 3 components which account for
approximately 67 % of the total cumulative variance in socio-economic and
livelihood vulnerability.
