Seawall at City of Male, Maldives

08-maale-maldives-670Japan International Cooperation Agency


The rise in the sea level brought about by global warming was a serious issue concerning survival for a state such as the Maldives which has an average elevation of 1.6 meters. When high tides flooded the capital city of Male’ in 1987 and 1988, more than half of the area of Male’ flooded, an outbreak of cholera occurred, and
almost six million dollars’ worth of damage was caused.  Against this background, Japan carried out a Development Study on the “disaster prevention plan of the coast of Male’ island” between 1991 and 1992, in response to the request by the Government of Maldives.  Then, in order to follow up on recommendations in the study, the Government of the Maldives requested Grant Aid from Japan for seawall construction on Male’ island
