Climate assessment for Ukraine.

April 2017

...In this situation, (click here) the forecast for Ukraine could be the following

In the case of business as usual, according to the World Bank, with no major changes in the economy or modes of production and consumption, the average temperature in Ukraine may rise by 3,2-4,5 degrees Celsius by 2100.

In this case, Ukraine awaits significant negative consequences primarily in the agriculture sector with increasing droughts, reduction of rainfall in the summer and peak temperatures (colder winters and hotter summers). It will have a negative impact on a number of crops and will require significant investments in the adaptation to climate change (e.g. irrigation technologies, projects for creating temperature changes resistant species, etc.). Overall, significant changes could be observed in seasonal events, such as early periods of flowering plants, and sudden cooling. These processes will have a negative impact on agriculture as well as on ecosystems as a whole.

Droughts and floods and other extreme weather events such as hurricanes are happening not only more frequent, but their devastating effects increase. Such nature disasters will become permanent, causing significant losses in the economy and threatening food security. Droughts and heatwaves, rainfall reduction in summer will also help to increase the frequency of forest fires and desertification of southern and south-eastern regions of Ukraine. In the context of floods the Carpathian mountain regions as well as the populated areas in the basins of the Dniester, Dnieper and smaller rivers are the most vulnerable. We have already experienced the floods on the Danube in 2005, on the Dniester in Transcarpathia in August 2008, the drought across Ukraine in 2007 and the record snowfall in western and central part of the country in March 2013.

At the same time the regions in the south of Ukraine may also suffer very likely due to the rising of the Black and Azov seas, which are part of the World ocean. For the last 100 years, world sea level has risen by an average of 178 mm, and continues to rise at a speed of 3.4 mm per year. Scientists warn that Crimea could become an island due to the isthmus flooding. Similarly, a  significant part of Odessa could go under water. Vylkove village may disappear altogether. Part of Kherson and Mykolayiv regions could as well find themselves underwater. This situation may also lead to the issue of access to the water resources, including drinking water....
