1.2.5 Comparative evaluation of the impact factors of Choice 1 and 2

    The evaluation presented above proves that the quantitative parameters of most of the factors with a direct impact on the environment depend on the volume of the construction and exploitation works, as well as on the area of the territory necessary for the construction of the deep water navigable canal. All these are examined as main factors in the comparative evaluation of the two choices (chart 1.2.1)

    The evaluation of the data in the chart show the fact that Choice 2 presents unquestionable advantages: the volume of the excavated soil in the exploitation period, stipulated by Choice 2 is 6.5 bigger than the volume envisaged by Choice 1 , but the volume of the excavated soil during the construction period, stipulated by Choice 2 is 23% of the volume of the excavated soil during the construction period. Moreover: within the Danube Natural Reserve, the volume of the excavated soil stipulated by Choice 1 is 50 times bigger than the volume stipulated by Choice 2.
    A similar conclusion can be drawn as far as the land area to be used for the construction works is concerned: Choice 1 provides for 547 ha within the Danube Natural Reserve to be used, including 414 ha for the permanent use, while Choice 2 provides for only 4 ha to be used.
    Conclusions:
        1. The evaluation of the impact factors done in the Experts' Technical Explanations with the respect to the choices of construction of a deep-water navigable canal, shows the fact that most of the impact factors, expected to be produced either during the construction period or during the exploitation period, depend, directly or indirectly, on the volume of the excavated soil and on the total area of the land to be used (exploited) in this respect. The quantitative comparison of these basic factors reveals the advantages Choice 2, on the Bystroe channel, has, as against Choice 1 , on the Solomonov - Jebriansk gulf. On various sections of the tract from Volkovo to the place where Danube flows into the sea, crossing the Danube Natural Reserve territory, there is a 1:50 scale between the volumes of the excavated soil, while between the areas of the land to be exploited, there is a 1:135 scale, to the advantage of Choice 2. Taking into account these criteria, the impact of Choice 1 on the territory of the Danube Natural Reserve is to be considered as unacceptable, especially having in mind the fact that some of the choices previously evaluated are more reasonable as far as the landscape of the Danube Natural Reserve is concerned.
        2. The assessment on the economic activities reveals the fact that the maritime and fluvial activities are particularly developed in this region, at a domestic and at an international level, as well. The most developed industrial activities of the region belong to the maritime field, such as the construction and reconditioning of ships or fishery industry. The development of the cities of the region depends mainly on the transportation flow on the Danube waterway.
        3. A decline of the navigation on the Ukrainian section of the Danube could be noticed during the latest years, as a necessary depth, acceptable to navigation, had not been maintained on the Prorva channel. The decline of the navigation caused the decline of the industrial and transportation centers. The construction of the Danube-Black Sea navigable canal is thus necessary for the economic regeneration of the region.
        4. Nowadays, the territory of the Delta Favors the development of agriculture, fishing and hunting. The land areas within the Danube Natural Reserve are used as meadows for cattle. On the Delta channels (including Bystroe), industrial fishery is well developed.
        5. The construction of the deep-water navigable canal shall obstruct the fishing in the area, but not some other economic activities on the territory of the Delta.
