Eutrophication is a serious problem in many water ways from China to the US gulf coast. It is believed to be caused by high P and N from erosion and run-off. Are there any good ways to control it?
In order to control eutrophication first you need to identify the sources. Depending on the sources, you have to decide your management strategy. These days, in most of the East Asian countries, non-point sources (especially agricultural activities) are identified as the prime source of nutrient export in the waterways because of high fertilizer consumption and summer monsoon. In China, multi-pond system found to be effective for controlling nutrient export from agricultural fields.You can also consider for other best management practices.In case of controlling the point sources of pollution, there are two ways such as technology-based controls and water quality-based controls. Hope my answer will shed some light on your query,
