LAKEWATCH 25: USING THE HEALTH OF THE WORLD’S LAKES AS AN INDICATOR OF GLOBAL ENVIRONMENTAL CHANGE

In 1999, ILEC launched a new, biennially updated project called LakeWatch 25 to examine the “health” of a selected group of lakes and reservoirs as a measure of environmental change at the global level. Due to time and resource constraints, it was decided to focus on 25 lakes and reservoirs thought to be representative of global water-related problems. Based on commissioned studies, review of national data banks, and information contained in the international scientific literature, ILEC concluded that deterioration of lake and reservoir ecosystems is readily evident on all inhabited continents due to eutrophication, acidification, toxic contamination, water level changes, siltation, salinization, and introduction of exotic species. In short, successful lake management requires a wide spectrum of pollution abatement measures along with sound ecological and environmental planning. These key requirements have not been followed in most developing countries, primarily because of financial constraints limiting their abilities to implement proper lake management programs. Developed countries can assist by facilitating technology transfer and know-how.
