Eutrophication of the East African Great Lakes
(Chapter; Bokkapittel, 2005-01-06)
Several of the African Great Lakes are distinctive for their very long water residence time >100 years. Incoming nutrients will be retained within the lakes and recovery will be slow even if inputs
are reduced. While changes in chemistry
and plankton composition of Lake Malawi have
not been extreme to date, strong eutrophication is already happening in Lake Victoria, where damage has reduced its ...
Integrated approaches to drainage basin nutrient inputs and coastal eutrophication: an introduction
(Chapter; Bokkapittel, 2005-01-06)
Ingress
Eutrophication is an increase in primary production
due to increased nutrient supply and its consequences.
In its widest sense eutrophication
means any increase of nutrient availability that increases
primary production. Frequently, however,
eutrophication is understood exclusively as the
consequence of nutrient input by anthropogenic
activities. The primary consequence of ...
Eutrophication, primary production and vertical export
(Chapter; Bokkapittel, 2005-01-06)
Introduction.
The effects of global and local changes are most
prominent at the land-sea margins where presently
population growth is greatest. For example, the
population of coastal counties of the USA has
roughly doubled since 1960 (Eos, 1992). This gives
rise to increased pressure on natural resources
and a large number of disturbances to coastal regions.
Presently, eutrophication of ...
Pelagic eutrophication in the Gulf of Riga
(Chapter; Bokkapittel, 2005-01-06)
Quantitative estimates of the fluxes and dynamics
in the nutrient load on marine environments, their
distribution and channelling through the food web
and the effect on the increase of new production,
are fundamental and constitute a prerequisite for
the planning of actions for water protection measures.
The Gulf of Riga is no exception. The Gulf
is a semi-enclosed part of the eastern Baltic ...
Cultural eutrophication: perspectives and prospects
(Chapter; Bokkapittel, 2005-01-06)
History of cultural eutrophication.
Cultural eutrophication is old as Homo sapiens. In
particular after the introduction of agriculture and
larger settlements eutrophication has been mans
faithful companion. During the pre-agricultural
hunting and picking stage only probably a couple
million humans inhabited the world and cultural
eutrophication was negligible. The 3 orders
of magnitude ...
