This volume is derived from a symposium on High Latitude Limnology
held during the 23rd Congress of the Societas Internationalis
Limnologiae in Hamilton, New Zealand. The symposium stemmed from
our belief that an exchange of views between limnologists working
in the north and south polar zones would be timely and productive.
Over the last decade there has been a major increase in the
limnological research effort in Antarctica with the expansion of
science programmes there by many nations from both the northern and
southern hemispheres. Freshwater research has also continued to
develop in the Arctic, stimulated by the need for basic information
to assess environmental impacts of the oil industry, mining,
urbanisation and other human activities. By bringing together
aquatic investigators from both poles we hope to draw attention to
the distinctive features that high latitude systems hold in common,
and to the marked contrasts between and within each zone. The
dominant impression from the assemblage of papers presented here is
one of great limnological diversity. The studies include clear,
turbid and brown water rivers in the sub Arctic (LaPerriere, Van
Nieuwenhuyse & Anderson); chlorophyte dominated streams in the
maritime Antarctic (Hawes); streams on the antarctic continent
lined with thick cyanobacterial mats (Howard-Williams &
Vincent); meromictic waters in the Arctic (Ouellet, Dickman, Bisson
& Page) and Antarctic (e. g.
The management of water supply and quality in lakes, rivers, and reservoirs has proceeded largely on the basis of local rather than global considerations. High-quality freshwater resources are now in critically short supply, not only because of local problems such as over-irrigation and eutrophication, but also as a result of large-scale impacts such as climate effects on the hydrosphere. This book explores the dichotomy of global strategies (international and generic) versus local strategies (site-specific) for lake, river, and reservoir management, and presents a series of contrasting perspectives on topics that include monitoring, modeling, water treatment, eutrophication, and restoration. The final chapter integrates these perspectives and identifies strengths, weaknesses, and complementary aspects of the two approaches to help refine future strategies for the sustainable use of the world's freshwater resources.

The globalization of trade, monetary and fiscal policies, capital
markets, and investment patterns is reshaping the world economy and
is leading to new financial, commercial, and marketing structures
as well as unprecedented economies of scale. Simultaneously,
national and international awareness and to strengthen. There is
consensus among responses to accelerating environmental degradation
continue most developed countries that the rapidly evolving new
economic order needs to be well integrated with policies to
maintain or restore environmental quality. Many challenges remain,
however, in evaluating the geo-ecological implications of economic
globalization, and in formulating the appropriate management
responses. In lakes and rivers, the management of water supply and
quality has largely proceeded on the basis of local considerations
rather than at the global scale that has been more typical of
environmental management of the atmosphere and ocean. It is
increasingly apparent, however, that high-quality water resources
are now in critically short supply not only because of local
problems such as over-irrigation and eutrophication, but also as a
result of larger-scale climate effects on the hydrosphere. This
magnitude of impact will increasingly require the integrated
monitoring and management of water resources on a planetary scale,
with world criteria for environmental assessment, restoration, and
conservation strategies. The increasing extent of world trade in
potable freshwater heightens the urgency for establishing
international approaches, criteria, and regulations.
