Stikstofimpact

Stikstofimpact refers to the consequences of excessive nitrogen deposition on ecosystems and human health. Nitrogen is an essential nutrient for plant growth, but when it enters the environment in large quantities, primarily through agricultural activities like fertilizer use and animal manure, and from burning fossil fuels, it can disrupt natural balances.

In natural areas, high nitrogen levels can lead to eutrophication, where an overgrowth of algae in water bodies depletes oxygen, harming aquatic life. On land, it can alter plant species composition, favoring fast-growing, nitrogen-loving plants that outcompete more sensitive species, leading to a loss of biodiversity. This can also weaken ecosystems, making them more susceptible to diseases and pests.

The impact of nitrogen also extends to air quality. Nitrogen oxides released from combustion processes contribute to the formation of fine particulate matter and ground-level ozone, both of which have detrimental effects on respiratory health. Furthermore, some nitrogen compounds can contribute to climate change through the emission of nitrous oxide, a potent greenhouse gas. Addressing stikstofimpact often involves strategies to reduce nitrogen emissions from agriculture and transport, such as optimizing fertilizer application, improving manure management, and promoting cleaner energy sources.
