| Zusammenfassung |
| In Albania, about one quarter of the country is occupied by outcroppings of
soluble rocks; thus, karst represents an important and typical natural
environment. Today karst areas are seriously threatened by a number of
hazards, of both natural and anthropogenic origin. Many problems are related
to agricultural practices: the use of heavy machinery, ever-increasing in
recent years, results at many sites in destruction of the original karst
landscapes. Use of pesticides and herbicides, in addition, causes the loss
of karst ecosystems of great biological relevance, as has been observed in
the Dumre district, where about 80 lakes of karst origin are present in the
evaporites of Permian-Triassic age. Agricultural practice performed on
slopes with medium to high gradient is a further factor which greatly
predispose the slopes to erosion. The cave heritage of Albania (estimated so
far in about 1000 caves) is at risk because of the uncontrolled quarrying
activities which determine the total or partial destruction of karst caves,
including many of naturalistic, archaeological and speleological interest.
Many caves have also become sites of illegal disposal of solid and liquid
wastes, which causes pollution of the karst ecosystems and of the aquifer
therein present, with heavy negative consequences on the quality of water.
Even though most of the cases here mentioned are related to anthropogenic
activities, the natural hazards, such as subsidence phenomena, floods, and
the development of sinkholes, have not to be disregarded. |
