- Description
- The global degradation of both marine and freshwater ecosystems is primarily driven by the excessive addition of anthropogenic nutrients to watersheds. Increased nitrogen loading, for example, can result in widespread ecosystem deterioration and may include harmful algal blooms, large scale fish kills, hypoxia, the loss of aquatic vegetation and habitat, loss of biodiversity, disruption of ecosystem functioning and the establishment of invasive species. Reactive nitrogen inputs (N) stem from intensive agricultural land use, resulting in the increased use of N-containing organic and inorganic fertilizers and/or animal manure and their consequent run-off and the discharge of human sewage. In recent years, aquatic ecosystem health has been monitored using a number of techniques, of which the most widely applied in South Africa is the South African Scoring System (SASS5; Dickens and Graham, 2002). Bio-monitoring, however, typically identifies eutrophication prob-lems only after ecosystem-level impacts have already occurred and where ecosystem health has been disrupted, it is often not possible to link biotic changes to identifiable causes (especially in the case of non-point source pollution). Any methods that would allow for the detection of emerging eutrophication which can also trace and identify nutrient sources would greatly improve our ability to effectively manage our aquatic resources.
