Dear colleagues,

  The 4th International Conference on Soils in Urban, Industrial, Traffic, Mining and Military Areas (SUITMA) is scheduled to be held at October, 2007 in Nanjing. The conference will discuss soil changes, problems, remediation, utilization, planning, in relation to urban ecological, environmental and biological health issues. The previous events were in Essen (Germany), Nancy (France) and Cairo (Egypt), respectively. We appreciate your continuous interest in SUITMA and welcome scientists, planners, policy-makers, to join the forth-coming event.

  The world is becoming more and more urbanized, and by which serious problems related to land resource use and ecosystem protection are emerged. Like the rest many parts of the world, China is also experiencing rapid urbanization and industrialization. We are honored to organize such a meeting in Nanjing, a beautiful, friendly ancient city, and believe that SUITMA4 in Nanjing may generate new knowledge and enrich our future collaboration possibilities. Therefore, on behalf of the organizing committee, I sincerely invite you to take part in the important event.
