24、related to aquifer overexploitation Aquifer overexploitation</p><p>　　The introduction lists several recent conferences which have highlighted overexploitation of aquifers. Within the conference proceedings,

25、 there is no single agreed definition of overexploitation. Spanish Legislation (Royal Decree 849/1986) defines it in article 171.2 in the following terms: “An aquifer shall be considered to be overexploited, or in danger

29、(physical, chemical, economic, ecological or social) which are negative for human life, now or in the future. This type of overexploitation should be avoided for moral reasons. For exploitation based on the extraction of
