As a result of the civil war between the Sinhalese government forces and Tamil rebels, which lasted for two decades, large parts of Sri Lanka – mainly Vanni and Jaffna regions – became densely covered with landmines and Unexploded Ordnance (UXO).
The Armistice Agreement, which came into force on 22 February 2002, made it possible to initiate a comprehensive humanitarian disarmament intervention in the north and east. NPA entered the country as the only international demining organization, in cooperation with the local partner Humanitarian Demining Unit (HDU), operated in government-controlled areas throughout 2007. At the end of the same year, NPA and HDU had demined roughly 18 km2 of land and destroyed more than 30,748 mines and items of UXO.
NPAs Humanitarian Disarmament Programme Sri Lanka concluded its work in January 2008.
