In this volume, we discuss the general impact of human societies upon lakes, as well as that experi- enced by lakes of selected parts of the Earth North America (and Lake Washington in particular), the Nordic and Alpine regions of Europe, Lake Baikal (by volume by far the worlds largest lake), the arid zone in general, and Latin America. We then go on to examine the problems created by human use of various different kinds of lakeshallow bodies of both the temperate zone and the tropics, reservoirs and other articial bodies. The volume then continues with an examina- tion of measures developed over the past 30 years in order to combat eutrophication (the most wide- spread environmental problem created by human impact on lakes, on a catchment scale), especially the use of catchment models to predict nutrient loadings from the land upon lakes, and of steady state and dynamic models better to understand the problem itself. This is then followed by a discus- sion of the general measures currently available to reverse eutrophication, and of one of these in particular (biomanipulation), and also those employed in order to restore acidied lakes. Final- ly, we give various authors the opportunity to de- scribe current and recent attempts to combat human impact on lakes, and to restore them to some state resembling stability, in various coun- tries or regions (North America, Nordic Europe, East Africa, South Africa), in the hope that these experiences may prove useful, if not inspirational, to colleagues elsewhere. In all of this, as also in Volume 1, the value of lakestheir immense scientic interest, their importance as threatened habitats, and for conser- vation of endangered species, their extreme impor- tance to the human community as a resourceis implicitly accepted as a given, in that to us, as limnologists, the value and importance of lakes is so overwhelmingly and blindingly obvious as to need no further amplication. However, if we, as scientists, are to be accountable to the society which pays our salaries, and which funds our re- search (a function which is today increasingly de- manded of us), and if we are to explain the value of whatwedotoawidersocietywhichhasneverbeen exposed to the fascinations of limnetic ecology, we need to be able to state explicitly: 1 just what it is that we nd so valuable (and in- deed marvellous) about these beautiful but some- times tantalising bodies of water; 2 just what it is we are restoring, when we propose thatwerestorelakestosomemoredesirablecondi- tion, and to spell this out in terms which involve using language with which we ourselves, as scien- tists, may be less comfortable. This may be because Science, because of its desire for objectivity, is inadequate to teach us all we need to know about valuing nature. Yet value in nature, like value in human life, is something we can see and experience (Rolston 1997, p. 61, my emphasis). 1 OntheValueofLakes PATRICK OSULLIVAN </li> <li> 4 p. osullivan Paradoxically, in attempting to do this, we may nd ourselves reaching out beyond the laboratory, into the wider community, and enlisting the support of the growing number of our fellow citi- zens who may lack sophisticated limnological knowledge, but who share our concern for nature in general, and hence for lakes. 1.2 LAKES AS A RESOURCE The human assault upon lakes is discussed in de- tail in the next chapter. Here, in order to begin dis- cussion of lakes as a resource in general, Table 1.1 depictsseveralofthemajorhumanusesoflakes,as related to water quality. It should be noted that the terms oligo- and eutrophic are used here according to their original meanings (i.e. in order to signify lake nutrient status or concentration [respec- tively, poorly and well-nourished; Hutchinson 1969, 1973; Rohde 1969; Edmondson 1991; OSul- livan 1995], and not lake biological productivity). Thus, for drinking water, oligotrophic waters, which are normally, by denition, cooler and more oxygenated, and therefore potentially con- tain fewer pathogenic microorganisms, and fewer plankton, and thus require less treatment, there- fore incurring fewer costs, are preferred. For bathing, mesotrophic waters are preferable to eu- trophic, if not required, although it is sometimes possible to share the latter with blooms of benign phytoplankton, provided other distractions are available (e.g. the Wansee in August). Non-bathing water sports are tolerable in eutrophic waters, but other recreational uses, particularly those where the aesthetic experience of lakes is as important, or more important, than their direct use, surely demand oligotrophic or mesotrophic waters, with their greater clarity, and general absence of water blooms and other nui- sances. Fish culture (in the developed world, at least) depends on the species involved, with salmonids preferring those oligotrophic waters originally shed (in Britain, anyway) only by gen- tlemen. Cyprinids, however, are tolerant of low- land, eutrophic waters, usually known (in that country) as coarse sheries, with all that the term implies regarding both nutrient and social status. The carp ponds of the Trebon district of South Bohemia (Czech Republic) represent an early de- velopment of what is often nowadays thought of as a new idea (i.e. permaculture; Mollison 1988), but Table1.1 Lake and reservoir use according to trophic status (after Bernhardt 1981) Use Required/preferredwater Tolerablewaterquality quality Drinking water Oligotrophic Mesotrophic Bathing Mesotrophic Slightlyeutrophic Recreation(non-bathing) Oligotrophic Mesotrophic Watersports(non-bathing) Mesotrophic Eutrophic Fishculture: salmonids Oligotrophic Mesotrophic cyprinids Eutrophic Commercial fisheries Mesotrophic, eutrophic Eutrophic Landscaping Mesotrophic Eutrophic Irrigation Eutrophic Stronglyeutrophic Industrialprocesses Mesotrophic Eutrophic Transport Mesotrophic Highlyeutrophic Energy(generation) Oligotrophic Mesotrophic Energy(cooling) Mesotrophic Eu...</li></ul>
