{"title":"GREENHOUSE GAS EMISSIONS FROM AGRICULTURAL ACTIVITIES AND THEIR DYNAMICS DURING 1990-2020","authors":"O. Tymoshchuk, O. Tymoshchuk, B. Matviychuk","doi":"10.35433/naturaljournal.1.2023.174-186","DOIUrl":"https://doi.org/10.35433/naturaljournal.1.2023.174-186","url":null,"abstract":"Ukraine, as a Party of the UN FCCC, cooperates with international organizations in the field of environmental protection, including ensuring the fulfillment of obligations in the field  of  climate change, namely to reach the level of greenhouse  gas emissions  in  2030 in  the  amount of  exceeded 60% of the level of 1990. The agricultural sector has a significant contribution to the total emissions of greenhouse gases in Ukraine, which during 1990-2020 fluctuated between 9-14%. In agriculture, the emissions of three  greenhouse  gases  (methane,  nitrous  oxide  and  carbon  dioxide)  are considered, the emissions of which lead to activity in two branches – livestock and plant growing. \u0000Livestock is characterized by such processes as enteric fermentation and manure management, which are accompanied by the emission of mainly methane. The key factors that determine the dynamics of greenhouse gas emissions in livestock are the number of agricultural animals and the type of manure management system, which is used to collect, transport, store and use manure. The largest contribution in terms of greenhouse gas emissions is made by the category of enteric fermentation (mainly enteric fermentation of cattle), the share of which during the 1990- 2020 fluctuated mainly in the range of 80-85%, and as of 2020 it decreased to 79.3%. \u0000The amount of emissions in plant growing is determined by factors specific to each process, namely: the amount of fertilizers (nitrogen and organic) applied to agricultural soils, the amount of applied liming materials, the amount of N in crop residues, the area of organic soils for crop planting etc. The main greenhouse gas in this area is  nitrous  oxide,  the  dynamics  of  whose  emission  is generally characterized by two directions – a significant and rapid reduction by  more  than  60%  by 2003 and subsequent gradual growth. The  development of  different  areas  of  plant  growing  takes place in different directions and with different intensity, and therefore have different contributions to the total volume of N2O emissions. The largest share of emissions, both in 1990 and in 2020, comes from N application with mineral fertilizers and N application with crop residues.","PeriodicalId":188435,"journal":{"name":"Ukrainian Journal of Natural Sciences","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121801617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to anthropogenic transformation of water bodies, this group of animals is recognized as one of the most vulnerable. The paper analyzes the dynamics of the frequency of occurrence and the state of Pseudanodonta complanata Rossmassler, 1835 populations over the last 100 years in Ukraine. This species of Unionidae is protected in many European countries, it was  included  in  the  Red  Data Book  of Ukraine in 2021 with the status \"vulnerable\". Three  different time periods  were chosen  to  analyze the distribution of P. complanata, the state of its populations in Ukraine and possible dynamics of changes. To establish the population characteristics of the species  in  water  bodies  about 100-50 years ago, an analysis was carried out based on the study  of  collections  of  shells  of  the  species stored in museums of the country and literature sources. To analyze the state of P. complanata populations in the second time interval, the results of our own collections carried out during 2007- 2012 within all river basins of Ukraine were chosen. In total, 300 sites were surveyed during this period. The third period of analysis covered the results of our own collections within the Central (Zhytomyr) Polissia in 2019-2022, 57 potential habitats of Unionidae were surveyed in the reservoirs and watercourses of the Teteriv, Sluch, Uzh and Ubort basins. In Ukraine, until the 70-80s of the twentieth century. P.complanata, despite its sporadic distribution, was quite widespread species. During the study period of 2007-2012, P. complanata was not recorded in the basin of the Western Bug, upper and lower Southern Bug, lower Dnipro, reservoirs of the Dnipro cascade, upper Siverskyi Donets and rivers of Azov and Crimea. In the collections of 2019-2022, the species was not found in any point. The results confirm the need to protect the vulnerable species and further develop conservation measures.","PeriodicalId":188435,"journal":{"name":"Ukrainian Journal of Natural Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
