Table 1.
Summary of new land reclaimed from the sea and areas with high vegetation cover.
Fig 1.
Newly reclaimed land in Singapore between 1988 and 2015.
Fig 2.
NDVI values in 2015 on reclaimed land.
More yellow colours indicate higher NDVI values, with more blue colours indicating lower NDVI values.
Fig 3.
The trend of NDVI across reclaimed areas only, Singapore without reclaimed areas, and Singapore with reclaimed areas across the study period.
Fig 4.
Temporal trends of NDVI on reclaimed land, from the first year of reclamation from water.
Black lines indicate median. Dark grey shading indicates 50th percentile. Lighter grey shading indicates 80th percentile. ‘N’ in the graph denotes the total number of sample pixels while ‘n’ in the graphs denotes pixels at each study site.
Table 2.
The models evaluated for this study.
Model 2 was chosen due to its lower AIC and higher R2 value.
Fig 5.
The modelled trend of NDVI when land first appears.
It takes 16.9 years for NDVI to increase to 0.7 that indicates dense vegetation. Confidence intervals shown in light grey, and are very small.
