Sumario: | Buenos Aires has experienced sustained population growth since 1580 and now has some 13 million inhabitants. The paper considers the main environmental problems affecting the Buenos Aires metropolitan area (AMBA)-flooding, water contamination (surficial and subterraneous water), soil degradation (contamination, physical and chemical degradation and agricultural land loss), domiciliary and industrial waste disposal and sanitary landfills, mining-derived problems, expansive soils and atmospheric contamination. It focuses on the geological and geomorphological aspects that have controlled their occurrence.
