Identifying key factors determining dynamics of environmental characteristics in Lesser Sunda island, Indonesia

The main purpose of this study was to identify the key factor of various environmental characteristics dynamics in Lesser Sunda island. This is significant to support effective and efficient conservation management planning that prioritized in the area. We retrieved the dataset for this study from a global database package. Moreover, a multivariate analysis for dimension reduction, such as Principal Component Analysis (PCA) was utilized. The result indicated that dimension of environmental characteristics in Lesser Sunda island be reduced to six dimensions by considering the eigen value. Moreover, the first two dimension that contribute most variance proportion suggested Sea Surface Temperature (SST), pH and distance to shore as the key determining factors of environmental changes in studied area. Therefore, these factors should be highly considered for marine conservation design in Lesser Sunda island.
