Hello, my name is Kristina, I'm from Tomsk. Ecosystem services in your living area. What ecosystem services do you have in and around your living area? Give at least one example for each of the four types of ecosystem services. Make clear in your answer where you can find the ecosystem service and what the ecosystem offers to your living area. The main services that surround me include: A. Provisioning services In Tomsk, ecosystem services can be found from forests and marshes. The territory of the Tomsk region is 63% of the taiga and 29% of the marshes. The remaining 8% are cities, i.e. 92% of the Tomsk region are taiga and marshes. The cost of taiga services in such a territory is approximately 60 billion a year and the cost of marsh services is 230 billion a year. In total, this is $ 290 billion a year. But we must understand that this does not mean that we will go sell Vasyuganskoe bog, which is quite expensive from the point of view of ecosystems. Also, ecosystem services can include food - it's the food itself, as well as the materials that we get from plants and animals. Water is drinking and water is not for drinking. B. Regulating services This is a water purification service - for example, treatment plants. Duration and magnitude of water flow, floods and replenishment of water reserves in underground aquifer systems. The ability of the natural system to accumulate water is affected by draining wetlands or replacing forests with agricultural land, urban areas. Services for air cleaning - for example, regulation of emissions of pollutants into the atmosphere. Ecosystems, on the one hand, release chemical compounds into the atmosphere, and on the other - remove them from the atmosphere, affecting many aspects of air quality. In Tomsk, three subscribers are dropping water for cleaning: the city in the person of Tomskvodokanal, Tomskneftekhim and TGK-11. The very system of sewage treatment plants was built in the early 80's, and belonged to Tomskneftekhim. Initially, these were only their local structures. In the early 90's, when the main production of the company went into recession, it was difficult to maintain the water treatment complex and it was transferred to the municipality for use. So Tomsk has become a unique city, where drains before the purification process and before the subsequent discharge into Tom pass a very long way: 4,5 km the pressure pipeline leads them to the treatment plant, and 33 km the gravity pipeline - to the river. In most cities, treatment facilities are located in the structure of the water canal and are one system with it. C. Habitat or Supporting services Services required to support all other ecosystem services. For example, the maintenance of soil fertility, as in Tomsk a significant number of agricultural areas. Pollination - maintenance of life cycles, protection of habitats and gene pools. These services also include biological control of diseases. D. Cultural services These are services that bring spiritual enlightenment, such as churches. Many religions attribute spiritual and religious values to ecosystems or their components. And also cultural enlightenment, for example museums, exhibitions. The diversity of ecosystems is one of the factors influencing the diversity of cultures. They can also include information services, such as television, radio, the Internet. Educational services - schools, universities, kindergartens.
