It is also common when sewage, either treated or untreated, enters a body of water, and when the outflow from septic tanks enters a stream or pond. As seen in Figure 2, cultural eutrophication is caused by human land use, including agriculture and residential or industrial developments. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays. Eutrophication occurs naturally over centuries as lakes age and are filled in with sediments (Carpenter 1981). Many lakes are naturally eutrophic and in some cases there is a progressive eutrophication as the lake matures. Cultural eutrophication happens when the amount of nutrients in the water and/or the water temperature are changed due to human activity, and the eutrophication process begins to run at high speed.

Decoupling agriculture from fossil fuels. speed of nutrient enrichment is faster. It is where eutrophication happens much faster because of human interference.. Human activities like farming and sewage disposal result in lots of extra phosphorus and nitrogen being flushed into streams and lakes, which eventually reach the ocean. They are important processes triggered by both natural and unnatural substances or occurrences that can’t be stopped by men when it has occurred. This view is based on a mis-understanding. There are two types of eutrophication: natural and cultural. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. Cultural eutrophication is when a flux of excess nutrients from human activity are added into a local run-off which in turns speeds up the natural eutrophication. Log in here.

The present eutrophication of the Baltic and North Sea was preceded by similar or even worse eutrophication periods caused by log-ging and the introduction of large-scale agriculture in Europe. The excessive algal growth came back three years later, causing problems to 500,000 residents of Toledo whose tap water was rendered hazardous to their health, when a toxic compound from the algae made its way into the city water supply.

As the nutrient availability increases, more plant growth is supported in the lake; this can include both benthic, or bottom-rooted, plants, and also those that float. eutrophication process beyond the rate associated with the natural process (e.g. The main difference between natural eutrophication and damaging cultural eutrophication is that in cultural eutrophication, the. It is sometimes defined as an increase in the rate of organic production or an increase in the total organic carbon. Fertilizers provide essential nutrients like nitrogen and phosphorus to the soil in which grass, vegetables and ornamental flowers grow. It is simply the increase in concentration of a substance in a food chain, not an organism. was more ‘natural’.
