The successor to GEO-2000 (1999) and complementary to it, GEO-3 describes policies and achievements in all areas of environmental concern since 1972. It analyses the drivers of environmental change and uses modelling techniques to project the impacts of different policies between 2002 and 2032. It is a crucial assessment for the Earth Summit in Johannesburg in September 2002 and for environmental policy and research worldwide.;It is clearly organized in accessible, non-technical language and supported by colour graphics and quick highlights. With full bibliography and index it should be useful for researchers, teachers, students and policy-makers in environmental science and policy, geography, politics and international affairs.
