A fuzzy MCDA framework for safety assessment in the remediation of a uranium mill tailings site in Ukraine

The Pridneprovsky Chemical Plant was one of the largest uranium processing enterprises in the former USSR, producing a huge amount of uranium residues. The Zapadnoe tailings site contains most of these residues. We propose a theoretical framework based on multicriteria decision analysis and fuzzy logic to analyze different remediation alternatives for the Zapadnoe tailings, which simultaneously accounts for potentially conflicting economic, social and environmental objectives. We build an objective hierarchy that includes all the relevant aspects. Fuzzy rather than precise values are proposed for use to evaluate remediation alternatives against the different criteria and to quantify preferences, such as the weights representing the relative importance of criteria identified in the objective hierarchy. Finally, we suggest that remediation alternatives should be evaluated by means of a fuzzy additive multi-attribute utility function and ranked on the basis of the respective trapezoidal fuzzy number representing their overall utility.

Sevastopol’’, Ukraine, 1854 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Plan Sevastopoli͡a s ukrʺplenīi͡ami ot rʺki Belʹbek do Balaklavy : i s oznachenĭemʹ vsʺkh osadnykh raspolozhenīĭ. It was published by Izd. A. Beggrova in 1854. Scale [ca. 1:53,000]. Covers Sevastopol’, Ukraine. Map in Russian. The image inside the map neatline is georeferenced to the surface of the earth and fit to the European Datum 1950, Universal Transverse Mercator (UTM) Zone 36N projected coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, territorial boundaries, shoreline features, roads, built-up areas, selected buildings including defenses and fortification related to he Siege of Sevastopol’, Ukraine, during the Crimean War, 1854-1855, and more. Relief shown by hachures.This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

Approximation to EU Technical Standards with and without the Promise of Membership: the Cases of Slovakia and Ukraine. EU Diplomacy Paper 02/2013

This paper aims to identify the extent to which the non-promise of membership of the European Union (EU) precludes the motivation of Ukraine as European Neighbourhood Policy country to adopt EU policies in the field of market access, namely technical standards and regulations. Its approximation approach is compared to the fast-tracked accession of Slovakia, which was driven by a clear-cut membership promise. Furthermore, the paper elaborates whether the conclusion of an Association Agreement between the EU and Ukraine, including a Deep and Comprehensive Free Trade Agreement, provides sufficient incentives for Ukraine to continue reforming its quality infrastructure in order to gain access to the Single European Market. Finally, scenarios of possible developments of EU-Ukraine relations are deliberated in the context of the EU-Ukraine-Russia triangle. The paper argues that market access provides sufficient stimulus for third countries to adhere to EU technical standards – even in the absence of a clear and credible promise of future EU membership. Yet, in the case of Ukraine, the country’s relations with Russia appear to compete with its EU approximation process, resulting for the time being in Ukraine attempting to pursue a balanced dual cooperation with both the EU and Russia.

Who lost Ukraine? CEPS Commentary, 16 December 2013

In his penetrating look at who lost Ukraine, Ivan Krastev finds that ultimately, everybody got Ukraine wrong. In his view, outsiders need to understand how high the stakes have recently become in the post-Soviet space, where two opposing integration projects are doomed to clash. He concludes that there are only three options left for Ukraine: sign the agreement with the EU, as the majority of Ukrainians want; join Putin’s EurAsEC, as the endangered political elite prefers; or go bankrupt.
