“…Karst areas are considered to be a vulnerable habitat for highly diversified vegetal and animal species (Juberthie and Decu 1994;Christman and Culver 2001) and the sediments and speleothems in caves have paleontological (Latham et al 2007) and paleoclimate significance (White 2004(White , 2007Sasowsky 2007). Due to a number of geological, morphological and hydrological features, karst areas are particularly prone to environmental degradation and irreversible landscape damages caused by the negative impact of human activities (White 1988;Gams et al 1993;Williams 1993;Nicod et al 1997;Akdim and Amyay 1999;Burri et al 1999;Urich 2002;Parise and Pascali 2003;Bonaccio 2004;Calò and Parise 2006;Sauro 2006;Parise and Gunn 2007). Urbanisation, stone clearing, deforestation and uncontrolled quarrying in catchment areas have transformed, disturbed and partially or totally destroyed the karst landscape causing modification of the surface and underground drainage, and deterioration in the quality of groundwater (Sauro 1993;Smith 1993;Frumkin 1999;Ginés 1999;Kacaroglu 1999;De Waele and Follesa 2004;Spizzico et al 2005;Delle Rose et al 2007;.…”

Geochemical characterization of surface water and spring water in SE Kashmir Valley, western Himalaya: Implications to water–rock interaction

et al. 2011

Water samples from precipitation, glacier melt, snow melt, glacial lake, streams and karst springs were collected across SE of Kashmir Valley, to understand the hydrogeochemical processes governing the evolution of the water in a natural and non-industrial area of western Himalayas. The time series data on solute chemistry suggest that the hydrochemical processes controlling the chemistry of spring waters is more complex than the surface water. This is attributed to more time available for infiltrating water to interact with the diverse host lithology. Total dissolved solids (TDS), in general, increases with decrease in altitude. However, high TDS of some streams at higher altitudes and low TDS of some springs at lower altitudes indicated contribution of high TDS waters from glacial lakes and low TDS waters from streams, respectively. The results show that some karst springs are recharged by surface water; Achabalnag by the Bringi stream and Andernag and Martandnag by the Liddar stream. Calcite dissolution, dedolomitization and silicate weathering were found to be the main processes controlling the chemistry of the spring waters and calcite dissolution as the dominant process in controlling the chemistry of the surface waters. The spring waters were undersaturated with respect to calcite and dolomite in most of the seasons except in November, which is attributed to the replenishment of the CO 2 by recharging waters during most of the seasons.

“…Stone clearing has actually become the most diffuse practice to gain new lands to agriculture (Akdim and Amyay, 1999;Burri et al, 1999). In past times, stones were cleared from the fields by hand, while the resulting detritus was generally used to build dry walls for protection, enclosures, or terrace support.…”

Abstract.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.

“…Globally, about 15% of the land area on earth is karst (Jiang & Yan, 2010), and karst areas are particularly prone to environmental degradation and irreversible landscape damage caused by the negative impact of human activities because of a number of geological, morphological and hydrological features (Burri et al, 1999;Urich, 2002;Parise & Gunn, 2007;Parise & Pascali, 2003;Williams, 1993). Rapid urbanisation, stone clearing, deforestation and uncontrolled quarrying has partially or totally destroyed karst landscapes causing modification of the spatial pattern of land use and deterioration of the fragile geological environment in the karst regions (Andriani & Walsh, 2009;De Waele & Follesa, 2004;Gines, 1999;Sauro, 1993Sauro, , 2006.…”

Urbanisation Induced Landscape Change of Urban Hills in Jinan City, Karst Geological Region of North China

Rapid economic development has induced urbanisation in China, especially in most of China's karst geological mountain regions. Jinan City belongs to the karst geological mountain region of north China and is well known for its fractured karst springs. The spatial pattern of its land use has been profoundly transformed by rapid urbanisation, and the urban hills are facing changes in the city. Although the urban area of Jinan City keeps enlarging and the dwelling conditions are increasingly improving, the destruction of Jinan's urban hills occurs owing to the mass construction of the market housing and excessive real estate investment in the karst mountainous region within the city, thereby resulting in the degradation of the urban mountainous environment and threatening the settlement safety of Jinan's residents.
