This book synthesizes current knowledge of regional-global linkages in four regions to demonstrate that study of environmental change on a regional scale can enhance understanding of global-scale environmental changes. The atmospheric circulation over Southern Africa links regional nutrient and pollutant sources to distant sinks affecting both regional and global ecosystem functioning. Extended human modification of land cover in East Asia has altered the complex surface-atmosphere exchanges impacting the Asian monsoon system. Biogenic and anthropogenic emissions over South Asia are implicated in changes in global tropospheric ozone and oceanic biogeochemical balances. Economic globalisation has negatively impacted regional environments of Southeast Asia.
