The cultural process is primarily associated with phosphorus common in fertilizers and treated sewage. Cultural eutrophication One of the most important types of water pollution , cultural eutrophication describes human-generated fertilization of water bodies. Controlling nutrient sources can greatly reduce eutrophication, and hence, governments and municipalities across the world should develop stringent measures to discourage on-point pollution. These poisonous substances include hydrogen sulfide and Other sources that contribute to cultural eutrophication include the use of fertilizers, faulty septic systems, and erosion into the lake. Fertilizers that contain phosphorus and nitrogen. The explosive growth of plants increases the demand for oxygen resulting in a reduced availability of dissolved oxygen for respiration by other aquatic plants and animals in the water. Causes of Eutrophication. Compost manure does not contain high elements of nitrates and phosphates that cause eutrophication. Similarly, naturally productive lakes can be fertilized further by human-derived point and nonpoint nutrient sources. ponds, lakes and any potential site for eutrophication so that it can be Besides, the algal blooms are highly toxic. Eutrophication is most often the result of human activity. These structural changes are based on three major causes of eutrophication which include: Cultural eutrophication is affecting millions of lakes, rivers, waterways and other various water bodies throughout the world. reduce their numbers within the water. - "The Globalization of Cultural Eutrophication in the Coastal Ocean: Causes and … Organic waste. Eutrophication is a widespread issue mainly in Northern America and Europe. In cultural eutrophication, however, humans inject large amounts of artificial matter into the water’s ecological system thus overwhelming the natural cycle thereby resulting in the water bodies changing from oligotrophic to eutrophic. Another main contributor of phosphorus and nitrogen nutrients are concentrated animal feeding operations (CAFOs). While eutrophication does pose problems, humans should be aware that natural runoff (which causes algal blooms in the wild) is common in … Any pollutants that get phosphorus and nitrogen into the water. increasing due to the process of eutrophication, these species will certainly the detergents. unfortunate demise. Under certain conditions of darkness and warm temperatures these blooms may die, decompose and produce offensive sewage-like odor. Strict action must be taken against them if they Explain to them the causes and effects of eutrophication and In the absence of oxygen, the microorganisms capable of living in the absence of oxygen start to decompose organic substances resulting in the release of harmful hydrogen sulphide and ammonia. Their presence in water bodies declines the availability of clean drinking water. Algae fouls the water and air. The process is characterized by excessive plant and algal growth in the water bodies. Eutrophication is predominantly caused by human action. A good scenario of how human activities affect the ecology of water bodies is when humans dump sewage into water bodies. Dead animals and plant materials are also decomposed by aerobic and anaerobic decomposers into simple forms that be easily recycled into the natural cycles. Abundant plant growth produces an undesirable disturbance to the balance of organisms and the quality of water. And as algae plants die and decompose, the oxygen continues to deplete, resulting in the suffocation of fish and other aquatic life forms. When water bodies are overly enriched with these nutrients, the growth of algae, plankton, and other simple plant life is favoured over … eutrophication. Even treated water should not be discharged back into rivers or lakes as it can also cause an accumulation of excess nutrients into the water bodies. Cultural denotes human involvement, and eutrophication means truly nourished, from the Greek word eutrophic. Later during my stint in medical school, I realized that many of our health concerns originate from neglecting our environmental responsibilities and this was just not sustainable in the long run. After discussing the serious consequences on the ecosystem due There are three main sources of anthropogenic nutrient input: erosion and leaching from fertilized agricultural areas, and sewage from cities and industrial waste water. 1. It’s a rapid process as it takes only decades to eutrify and ultimately pollutes the water. The explosive growth of the algae and plants can lead to the development of extensive and dense mats of floating plants that make it difficult to set fishing nets in the water. suddenly change the nature of the nearby water body. Cultural eutrophication or nutrient over-enrichment, especially of nitrogen and phosphorus, has degraded many coastal waters and has been invoked as a major cause of seagrass disappearance worldwide (e.g. FIGURE 2 | Global distribution of eutrophic coastal marine ecosystems (adapted from Breitburg et al., 2018). Since pollution is a leading cause of eutrophication, reducing it in various forms can help prevent further destruction of water bodies. Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. Cultural Eutrophication: This process is generally speeded up by human activi­ties; which are responsible for the addition of 80% nitrogen and 75% phosphorus to lakes and streams. Introduce species which feed on algae and cyanobacteria to Dumping untreated sewage into a water body, for example, results in the fertilization of the algae, increasing their growth. how their actions can help prevent eutrophication. But first, let's look at what causes eutrophication. Rivers, Lakes. Moreover, eutrophication does not only happens in water, it is also present in the soil. It is also the responsibility of the ecosystem to survive and respire. Ecosystem Importance of Keystone Species 17 Examples of Keystone…. Eutrophication encourages the growth of cyanobacteria. This generally describes the concept of cultural eutrophication. Cultural eutrophication, on the other hand, refers to an alteration of nutrient input in the water basins by human activities that lead to major ecological changes in water bodies over the decades. production of algae and aquatic plants resulting in a decrease in the number of What is more, the dense growth of algal blooms and other plants can block water supply systems limiting the availability of piped water. government to carry out these investigations. The use of fertilizers, especially nitrate and phosphate fertilizers on farms, lawns, and golf courses, result in the accumulation of phosphate and nitrate in the nearby water body sources. As there is no photosynthesis Causes of Eutrophication and Algal bloom | UPSC – IAS. Algae and cyanobacteria make the water almost impossible to Improvements must be carried out in the water treatment grows uncontrollably, making a large amount of organic mass which starts to degrade. the water further depleting the oxygen concentration. be restricted especially in those areas which are likely to undergo Once the nutrients get into lakes, oceans, rivers, and other water bodies; algae, and plankton, among other aquatic plant life become well-fed resulting in an increase of their photosynthesis activity. This acceleration of nutrient inputs to surface waters is termed cultural eutrophication. Fertilizers. Cultural eutrophication causes excessive algal bloom in water bodies, with consequent algal overload. to reach the photosynthetic organisms of that water body and this makes it Eutrophication is a serious environmental problem which The poison can cause death to humans and animals if ingested at the least concentration in drinking water. The concept of cultural eutrophication is particularly brought about by a human understanding that clear water with minimal visible organisms is better than organic-rich water. Use of fertilizers on farmlands that are washed away from soil into rivers and lakes. Man-made causes (Cultural eutrophication): This process is generally speeded up by human activities. eutrophication and how the populations are increasing the chances of this, serious actions need to be taken to prevent further damage from this oxygen-dependent species start to suck out as much as oxygen as they can from When humans cut trees, they increase the likeliness of eutrophication. Furthermore, all essential elements of compost manure are broken down and synthesized by plants avoiding the eutrophication cycle. turn reduces the amount of species in the ecosystem. https://www.britannica.com/science/cultural-eutrophication, https://www.nature.com/scitable/knowledge/library/eutrophication-causes-consequences-and-controls-in-aquatic-102364466/, https://www.encyclopedia.com/environment/encyclopedias-almanacs-transcripts-and-maps/cultural-eutrophication, Rinkesh The deprivation of oxygen and the formation of toxic compounds lead to a decrease in the number of species and the loss of biodiversity within the ecosystem. Over the last few years, tech developers and scientists have been working towards creating technologies that can help reduce pollution and even reverse the damages already caused. The use of fertilizers, especially nitrate and phosphate fertilizers on farms, lawns, and golf courses, result in the accumulation of phosphate and nitrate in the nearby water body sources. The use of fertilizers is the leading cause of eutrophication. nitrites. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem. start to die eventually creating a dead zone with no species or oxygen this regard. 13437 shares The water bodies are well-suited to deal with the matter cycling preserving the water quality. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. process. The eutrophication in water causes many complexities not only for aquatic animals but also for the animals on land. Eutrophication increases the growth of algae and minute plants as well as photosynthetic bacteria. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. Mostly, eutrophication leads to easily detectable algal blooms which turn the water green in color as there are numerous amount of algae situated on the surface of the water. The growth, especially on the surface, will negatively affect activities such as boating and swimming. Ultrasonic irradiation, as an example, is one such technology that has tremendously helped in controlling eutrophication by causing cavitations that produce free radicals that destroy algae cells.
