affected by multiple factors of degradations. Mangrove degradation checklists are
prepared on the basis of the above investigations on recent environmental changes
of Sundarban for identification of potential threats and formulation of conservation
strategies of mangroves (Tables 11.1, 11.2, and 11.3) (Table 11.4).
11.4.3 Factor Analysis (PCA) for Mangrove Degradation
Related Factors and their Sub-factors
Several factors of mangrove degradation have been identified from the above analysis in the case of Southwest Sundaraban (India). These factors and sub-factors are
analyzed on the basis of the PCA method to categorize them in a sequential order for
the case studies of individual islands according to the following statistical values.
Fig. 11.10 Vegetation vigourness status (Health) of mangroves in the coastal wetlands of southwestern Sundarban (1989–2015) is positively correlated with density differences of mangroves in
spatio-temporal condition. The attractive health of mangroves is recorded only in those areas of the
islands where fresh silt accumulation and tidal drainage are present
