The mangrove ecosystem receives freshwater
from four sources, namely (i) Coringa River (ii)
Gaderu River, (iii) Distributaries of Gautami-
Godavari River and (iv) neritic waters from Ka-
kinada Bay.
The major threats operating on mangroves of
Coringa are tabulated in brief (Table

The assessment of the health of the man-

3.3.1 Assessment of Blue Carbon
Through Remote Sensing
The blue carbon can also be assessed through
remote sensing. A case study from critical habitat
information system for Coringa mangrove in
Andhra Pradesh (India) (DOD
2001
) reveals that
mangroves have been severely depleted in this
region. The Coringa mangrove situated about
150 km South of Visakhapatnam (16

1998 were analysed to detect the variation using
the overlay facilities of GIS. Table

reveals the major land-use/land cover features
and their respective area in 1988 and 1998 within
Coringa Reserve Forest and its extension.
