  • From drawing cognitive maps to knowing the protection zones for drinking water resources
  • Drinking water ; Enquiry ; Mental map ; Nature conservation ; Protected area ; Slovenia ; Water resources
  • Using a sample of 900 persons from the urban area of Ljubljansko polje and the suburban area of Iški vršaj, we tried to determine how much local residents knew about the protection zones for drinking water resources. We employed a survey
  • questionnaire and the drawing of cognitive maps. A little fewer than half of the people are aware they live in water protection zones. The proportions of those who are aware of the protection zones in Ljubljansko polje (two fifths) and in Iški vršaj (two thirds

  • The article presents potential and actual sources of groundwater contamination on the Kras plateau, which is the recharge area of the Klariči karst water source that provides drinking water for the Kras plateau and Koprsko primorje. The water source
  • is insufficiently protected due to inadequate water protection policy and the control over the implementation of the provisions has often been ineffective. Untreated wastewaters, illegal waste-disposal dumps and traffic endanger the water source. The hazards
  • are shown on a simplified map that could be, in a suitable scale, a valuable practical tool for further water source protection and in land-use planning. - (IKR)

  • Based on the analysis of the interaction mechanism between water utilization structure and industrial structure in arid inland river basins of Northwest China, the AA. constructed a System Dynamic Model for their mutual optimization. It aims
  • at coordinating the relationships between the water utilization-industrial structure system, the ecology-production-living system, and the upper-middle-lower reaches, so as to achieve a benign circle of eco-environment, a sustainable and efficient production
