General View of the WAVES Program

摘要: The globalization of the world’s economy at dawn new millennium is most likely to continue and will be accompanied by social environmental changes that affect entire earth system. causes global problems are not fully understood: emission greenhouse gases pollutants industrialized world, overuse soil biotic resources, destruction forests natural vegetation, extinction ecosystems with their genetic resources (WBGU 1993; IPCC 1997). In addition, consumption pollution even more pronounced through rapidly growing population. totality these processes, interactions consequences called change. observed symptoms interdependent interrelated in various ways. Global change therefore a complex phenomenon, which cannot completely understood analysis evaluation single phenomena. understanding its impacts necessitates relevant system components interactions. When using scenario assumptions, effects can described simulation runs models visualized as average values principal components. However, results very general mask strong regional differences (Walker Steffens 1999). At level, may vary considerably due geographical location, climatic variability, well socio-economic conditions.
