An environmental conflict in Hungary: bauxite or medicinal water?

Pages 71-74

Abstract

The economic expansion under the socialist regime led to environmental crises ill some regions of Hungary, The technology of bauxite inkling in the Transdanubian Mountains is a typical example for a prominent activity causing far-reaching environmental impacts and attracting great attention. The lasting deleterious effects of mining are manifested in water and related physical processes and in regional management. Environmental degradation began with the introduction of active de-watering technology in the exploitation of bauxite and coal in the early 1960s. The applied technology caused an average 30 m dropping of karst-water level over an area of 3,000 km?. It reached its lowest level (110m) in die major mining region in the western portion, at Nyirad. Many wells and springs of the region dried out, including the most abundant Hungarian spring at Tapalcafo. The world famous and unique spa, Hevlz, with incomparable balneological medical, recreational and infrastructural value, situated only 6 km from the southwestern basin of Lake Balaton, was also affected. Due to academic argumentation and pressure from local authorities, die government decided to close down the deep bauxite mine at Nyirad. This measure was followed by a slow rising of the karsrwatcr table, also in the Heviz spa region. As there has been no recultivation, however, the pits and caverns resulting from mining can still be seen, In the paper the landforms related to mining are presented and micro-scale changes in land use are detected in the environs of Nyirad.
