Rising sea-levels
In the past 25 years, sea level has risen at a rate almost
double the global average. This is due to a combination of
factors including land subsistence patterns.m Due to continuous
submergence in higher water, as an implication of rise of sea
level, the plants are being noted to be shorter and narrower
with fewer branches and leaves resulting in lower rates of
photosynthesis and regeneration of the mangroves.n The sea
level rise is also affecting the availability of sediment, directly
impeding the establishment of new groves.
