Ecological and Cultural Price of Irrigation¶
Ecological and cultural price of irrigation — aggregate of long-term negative ecological, economic, and cultural-historical consequences for mainland Ukraine caused by the construction of the Kakhovka Reservoir and North Crimean Canal in the 1950s.
Overview¶
To solve the problem of water supply and irrigation of arid lands of the Crimean Peninsula and Southern Ukraine, Soviet leadership chose the most costly and technocratic option — the creation of the so-called "Kakhovka Sea." Despite achieving economic goals in Crimea, mainland Ukraine suffered devastating environmental losses, flooding of the most fertile lands, coastal erosion, waterlogging of mines, and the destruction of the sacred Cossack heritage of the Lower Dnieper region.
Key Details / Subtopics¶
- Waterlogging and land destruction: A negative consequence was the waterlogging of large tracts of agricultural land, adjacent settlements, and industrial facilities (specifically coal and iron ore mines in Dnipropetrovsk Oblast). Unreinforced shores of the Kakhovka Reservoir undergo constant abrasion, absorbing several meters of coastline each year.
- Loss of natural biological filter: Dnieper floodplains (plavni) naturally purified Dnieper water before its discharge into the Black Sea and enriched the sea with plankton. Their destruction dealt a devastating blow to the ecology of the Dnieper and Konka rivers, deteriorating drinking water quality throughout the Lower Dnieper region.
- Cyanobacterial blooms: In shallow areas of the reservoir, uncontrolled reproduction of cyanobacteria (blue-green algae) occurs annually, accompanied by fish kills, release of strong foul odors, and health threats to the local population.
- Cultural-historical losses: Flooding of Velykyi Luh — destruction of over a hundred ancient Cossack villages, wintering quarters (zymivnyky), sacred places of the Zaporozhian Sich, and mass displacement of Ukrainians from their historical lands.
- Disregard for alternative projects: Scientists and the public proposed less costly and ecologically safe options for watering Crimea without flooding millions of hectares of fertile land, but Soviet authorities ignored these warnings.
