Latin America Hosts Workshop on
Eutrophication Management
The majority of lakes
and reservoirs in Latin America suffer eutrophication due to nutrient loading —
phosphorous, nitrogen, silica and organic matter — originating from point and
non-point sources. Eutrophication leads to degraded water quality and reduced
biodiversity, and on occasion can cause algae blooms (cyanobacteria) that
produce potent toxins, known as mycrocystins. These toxic compounds have been
found to cause acute liver damage in cattle, even at very low concentrations,
and there are reports of people dying due to the toxin in drinking water.
Eutrophication is closely tied to the interaction between society and aquatic
ecosystems. As a result, awareness of numerous factors is fundamental to
understanding the eutrophication process, its control and prevention. These
include economic development, awareness and participation by citizens in the
protection and rational use of water resources, cultural issues, legal and
institutional aspects, as well as managerial and technological approaches.
In general, training activities related to eutrophication management fail to
consider these factors in combination, leading to unsatisfactory results. In
response to this problem, IETC has produced a comprehensive reference book and a
student guide that take a comprehensive view of the problem of eutrophication.
Regional workshops in Africa and Southeast Asia have already been undertaken
using these publications, and the need to undertake a workshop in Latin America
has increased as eutrophication has become more apparent in the region’s water
bodies.
To this end, in April, IETC and the National Institute of Water (INA) of
Argentina ran a training workshop on eutrophication management for the Latin
American Region. Thirty national experts on freshwater resources management were
trained using IETC publications translated into Spanish by INA. In addition, the
training included a special session on modeling using Pilot Version 2.0
(PAMOLARE) produced by IETC, the University of Kyoto and the International Lake
Environment Committee (ILEC).
| UNEP IETC to Act as Focal
Point for 3rd Water Forum
In mid-April, in
cooperation with other organisations — including UNESCO, the International Water
Association, the International Council for Local Environmental Initiatives,
Shiga Prefecture and the International Lake Environment Committee (ILEC) — UNEP
IETC registered four proposals with the Secretariat of the 3rd World Water Forum
(WWF3) for sessions to be held in Kyoto, Osaka, and Shiga, Japan, next March. As
the focal point for UNEP, UNEP IETC will be co-convener of the session, “The
Future of the World’s Lakes, Principles for Action: Development of World Lake
Vision.” The conveners are ILEC, Shiga Prefecture, and others, based on the
results of the 9th World Lake Conference held last November in Shiga, Japan.
UNEP IETC has now begun accelerating its efforts to prepare for WWF3.
