Impact Of Agricultural Land Use On Some Hungarian Karst Regions, Ilona Bárány-Kevei
Impact Of Agricultural Land Use On Some Hungarian Karst Regions, Ilona Bárány-Kevei
International Journal of Speleology
The karst regions are found in the medium altitude mountains of Hungary. Their land use types are natural and sustainable forestry, grazing and vineyards. In international comparison, Hungary belongs to those countries of Europe where arable land is abundant, therefore, in the future its extension has to be reduced. That means agricultural activity has to be restricted on the sensitive karst surfaces. This paper presents ways of sustainable forestry and other land use types for three karst regions of Hungary.

Karst And Agriculture In Australia, David Gillieson, Mia Thurgate
International Journal of Speleology
Much of the development and degradation of karst lands in Australia has occurred in the last two centuries since European settlement. Recent prolonged El Niño events add further climatic uncertainty and place real constraints on sustainable agriculture. The lower southeast of South Australia is perhaps the one area in Australia where karst, and particularly karst hydrology, impinge on the daily lives of the community in that pollution and overexploitation of the aquifer are readily apparent to the local population. Effluent from intensive dairy farms, piggeries and cheese factories enters the karst and has caused concern over pollution of water supplies. …
Sustainable Development Of Agriculture In Karst Areas, South China, Linhua Song
Sustainable Development Of Agriculture In Karst Areas, South China, Linhua Song
International Journal of Speleology
The exposed carbonate rocks aged from Sinian to Mid-Triassic Periods cover an area of 500,000 km2 in south-west China. In karst areas with spectacular landscapes characterized by magnificent tower karst and conical karst, rare surface drainage systems and prevalent subsurface drainage systems, the environment is ecologically very fragile. The rapid increase of population, over deforested and cultivated lands, worsted the ecological system, causing a higher frequency of draught, flood and various disasters, backward economic development, low living standard of the people. In order to improve the sustainability of the agriculture the experience shows that the following operations should be …
