Diyawannawa
is
situated
around
the
parliament
of
sri
lanka.
Urban
wetland
environment.
Added
value
to
sri
lankan
administrative
capital.
A
lots
of
mangroves
and
related
animals
birds
and
crocadiles.
Beautiful
area
however.
Diyawanna
Lake
or
Parliament
Lake,
is
one
of
the
lakes
within
Sri
Jayawardenepura
Kotte,
Sri
Lanka.
It
is
quite
popular
as
the
Sri
Lankan
Parliament
Building
was
built
on
an
artificial
island
at
the
center
of
the
lake.
The
Diyatha
Uyana
park
is
also
located
on
the
banks
of
this
lake.
This
lake
was
created
in
1979
and
has
eight
islands.
In
contemporary
Sri
Lanka,
urban
wetland
eco-systems
could
generate
a
wide
spectrum
of
its
services
in
the
face
of
a
growing
demand
for
recreational
opportunities
and
amenities
from
the
urban
residents.
Diyawanna
Oya
wetland,
which
is
already
proved
to
be
an
important
recreational
site
in
the
greater
Colombo
area,
is
prone
to
severe
threats
from
illegal
reclamation
and
constructions
for
urban
development
purposes.
The
value
of
Diyawanna
Oya
wetland
is
threefold;
first,
it
provides
a
good
recreational
ground
for
exercise,
sports
and
family
outings;
second,
inhabitants
in
surrounding
areas
use
this
as
a
source
of
income
from
fishing,
cattle
grazing,
collecting
reeds,
rushes
and
fuel
wood;
and
finally,
from
the
environmental
point
of
view,
this
wetland
constitutes
an
important
flood
retention
area
and
a
rich
habitat
of
indigenous
fauna
and
flora.
Thus,
it
contributes
significantly
to
the
social
well-being
of
the
urban
and
sub-urban
society.
None
of
these
use
or
non-use
values
of
Diyawanna
Oya
site
has
been
recognized
adequately
and
instead,
dumping
of
garbage
and
reclamation
of
land
in
this
area
have
become
serious
threats
at
present.
This
study
attempts
to
estimate
the
economic
value
of
this
natural
resource
based
on
the
perceptions
of
the
regular
visitors
of
the
site
on
the
recreational
value
and
their
preference
to
conserve
this
endangered
and
under-appreciated
resource
using
the
Travel
Cost
Method
(TCM).
The
findings
indicate
that
the
Diyawanna
Oya
wet
lands
generate
an
annual
consumer
surplus
of
Rs.
3,890
million
to
people
who
use
the
area
for
recreation.
The
welfare
loss
from
converting
the
natural
wet
land
area
to
development
projects
is
Rs.
19.45
million
per
hectare
which
is
equal
to
Rs.
49,
246
per
perches.
The
study
highlights
the
need
for
more
to
be
done
to
conserve
the
wet
lands
and
suggests
a
number
of
ways
of
generating
revenue
that
could
be
used
to
fund
wet
land
conservation
and
enhancement
