Decision-Making for Eutrophication Management and Control

The scientific understanding of eutrophication, at least in temperate middle latitudes, is sufficiently well known that the control of eutrophication is a matter of political will, necessary finance, and effective institutional organization. The principal technical deficiencies, especially in developing countries, tend to be: (a) the absence of adequate water quality standards (and enforcement of these) against which to assess the severity of eutrophication, and (b) the absence of data with which to develop remedial options.

Monitoring programs should reflect the types of decisions that need to be made to carry out the following management tasks:

  • Identify relative contributions of different pollutant sources.
  • Allow calculation of nutrient input/output budgets into the receiving river, lake, or reservoir.
  • Predict change in ecological condition that would result from specific management interventions.
  • Assess alternative management interventions in terms of cost/benefit.
