Eutrophication can be defined “is the process of nutrient enrichment (usually by nitrogen and phosphorus) in aquatic ecosystems such that the productivity of the system ceases to be limited by the availability of nutrients. It occurs naturally over geological time, but maybe accelerated by human activities (e.g. sewage disposal or land drainage”(. David J. Hardisty. Sauder School of Business.
