SYMPOSIUM ON
CONSERVATION, RESTORATION AND MANAGEMENT OF AQUATIC ECOSYSTEMS
LAKE 2002
http://ces.iisc.ernet.in/energy/water20/Lake2002.html
December 9 - 13, 2002
Satish Dhawan Auditorium (CSIC Auditorium)
Indian Institute of Science (IISc) Campus
Organised by
Centre for Ecological Sciences, IISc, Bangalore
Karnataka Environment Research Foundation, Bangalore
Commonwealth of Learning, Canada
AQUATIC ECOSYSTEMS perform numerous valuable environmental functions. They
recycle nutrients, purify water, recharge ground water, augment and maintain
stream
flow, and provide habitat for a wide variety of flora and fauna and recreati
n for
people. A rapid population increase accompanied by unplanned developmental w
rks
has led to the pollution of surface waters due to residential, agricultural,
commercial
and industrial wastes / effluents and decline in the number of waterbodies.
ncreased
demands for drainage of wetlands have been accommodated by channelisation,
resulting in further loss of stream habitat, which has led to aquatic organi
ms
becoming extinct or imperiled in increasing numbers and to the impairment of
many
beneficial uses of water, including drinking, swimming and fishing. Various
anthropogenic activities have altered the physical, chemical and biological
rocesses
within aquatic ecosystems. An integrated and accelerated effort toward envir
nmental
restoration and preservation is needed to stop further degradation of these
ragile
ecosystems. Failure to restore these ecosystems will result in sharply incre
sed
environmental costs later, in the extinction of species or ecosystem types,
nd in
permanent ecological damage.
Aquatic Ecosystem Restoration means to restore degraded ecosystems to a leve
that
can be permanently sustained through protection and conservation. More reali
tically,
restoration mitigates, effects or remediates degraded ecosystems to levels t
at have a
higher order of ecological sustainability. Restoration can occur naturally,
ut usually
involves reductions of stresses such as nutrient or contaminant loads. Asses
ments of
degraded aquatic ecosystems allow decisions to be made as to what to control
in
order to remediate effects, or how much can be relied on nature to clean its
lf. To
achieve ecosystem stability or sustainability, decisions on what to do, incl
ding in situ
options such as bioremediation or biomanipulation, as well as the developmen
of
ecosystem indicators of progress towards restoration have to be taken. Resto
ation
towards a less degraded, but not necessarily pristine ecosystem, requires de
isions
as to how far the ecosystem has to be restored. To arrive at such conclusion
and to
monitor progress towards them requires the development of indicators of ecos
stem
health, stability and sustainability. If these criteria are met, the ecosyst
m can be
declared as remediated to acceptable conditions, perhaps even restored. The
evel of
protection or control or regulation required to reach this state is dependen
on the
recovery or restoration of the ecosystem and the state that needs to be main
ained.
Restoration means the degraded aquatic ecosystems are remediated to some lev
l of
stability or sustainability involving minimization of stresses, in situ trea
ments, and
probably conservation of components of the total aquatic ecosystem that have
not yet
been degraded.
Restoration is viewed in watershed context. Abatement of eutrophication, sil
ation and
contaminant problems are more effective when inputs are controlled. Reductio
of
inputs enhances the long-term effectiveness of in-lake approaches. The water
hed is
the natural scale for restoration and would be self sustaining. Effective re
toration can
be achieved through collaboration among scientists, economists, managers, po
icy
makers and local people. The proposed Lake 2002 symposium on conservation,
restoration and management of aquatic ecosystems will enable planners, scien
ists,
administrators and NGO's concerned with watershed development in the region
o
discuss the various aspects involved in the management of wetlands. This wil
enable
better understanding of the hydrology, water and land resource development
programmes and monitoring of their performance for sustainable development.
OBJECTIVES
The main objective of the symposium is to bring out the current trends in aq
atic
ecosystem conservation, restoration and management including the hydrologica
and
the biophysical aspects, peoples participation and the role of non-governmen
al,
educational and the governmental organisations and future research needs for
the
restoration, conservation and management. This also provides a forum for
researchers, technologists, economists, sociologists and others to meet and
iscuss
water related issues. Lake 2002 will:
* introduce the major types of aquatic ecosystem and the type and diversit
of
organisms characteristic of and important to each other;
* describe the main physical and biological processes important in severa
major types of aquatic ecosystems, and their consequences for community
structure and function; and
* outline some problems of management and conservation in aquatic
ecosystems.
SCOPE
Papers are invited on the following themes from researchers, planners, devel
pment
managers, students, economists, social scientists and individuals interested
in
conservation. Topics to be addressed include, but are not limited to -
* Limnology of lakes, reservoirs and wetlands;
* Watershed hydrology / Urban hydrology;
* Ground water and hydrogeology;
* Monitoring and modeling;
* Restoration methodologies and conservation strategies;
* Remediation measures;
* Integrated management of water quality and quantity with ecosystem
protection;
* Land use, urban planning;
* Geographic Information System (GIS), remote sensing; and
* Sustainable water resources management and water resources policy.
AWARDS
Best paper presentation award: Award carrying a citation and cash prize of
Rs. 2000 is given for the best paper presentation by a student.
*Best poster presentation award: Award carrying a citation and cash prize of
Rs. 2000 is given for the best poster presentation by a student. (Certificat
on
of student status at the time of the symposium is a pre-requisite for compet
ng
for awards).
EXHIBITION
An exhibition of software and hardware related to Restoration and
Monitoring technologies, Geographic Information System (GIS),
Global Positioning System (GPS), Remote sensing, Image
processing and Cartography, as well as products and services of
other organisations and agencies working in the area related to the
theme of the conference, will be organised. Organisations / Agencies
can participate in the exhibition on payment of fee of Rs.15, 000.
Registered agencies would be allowed to make 15 minutes
presentation. Interested agencies may contact Dr. T.V. Ramachandra
and remit the fee through DD drawn in favour of "Lake 2002-
Conservation, Restoration and Management of Aquatic
Ecosystems" payable at Bangalore.

Subject: bumblebees
Ecology listserv: I am studying the pollination of Impatiens capensis in
Vermont and I'm finding that both Apis and Bombus are either less abundant
or later in their foraging activity than previous years. By this time last
year, we were seeing 30-50 bees per hour visiting jewelweed flowers; this
year there are fewer than 5 per hour. I'm wondering if other pollination or
bee biologists are finding the same thing, particularly those in New
England.
