Grenada relies on tourism as its main source of foreign exchange especially since the construction of an international airport in 1985. Hurricanes Ivan (2004) and Emily (2005) severely damaged the agricultural sector - particularly nutmeg and cocoa cultivation - which had been a key driver of economic growth. Grenada has rebounded from the devastating effects of the hurricanes but is now saddled with the debt burden from the rebuilding process. Public debt-to-GDP is nearly 110%, leaving the THOMAS administration limited room to engage in public investments and social spending. Strong performances in construction and manufacturing, together with the development of tourism and an offshore financial industry, have also contributed to growth in national output; however, economic growth remained stagnant in 2010-12 after a sizeable contraction in 2009, because of the global economic slowdown's effects on tourism and remittances.
