The Greek Cypriot economy is prosperous but highly susceptible to external shocks. Erratic growth rates over the past decade reflect the economy's vulnerability to swings in tourist arrivals, caused by political instability in the region and fluctuations in economic conditions in Western Europe. Economic policy is focused on meeting the criteria for admission to the EU. EU-driven tax reforms in 2003 have introduced fiscal imbalances, which, coupled with a sluggish tourism sector, have resulted in growing fiscal deficits. As in the Turkish sector, water shortages are a perennial problem; a few desalination plants are now on-line. After 10 years of drought, the country received substantial rainfall from 2001-03, alleviating immediate concerns. The Turkish Cypriot economy has roughly one-third of the per capita GDP of the south. Because it is recognized only by Turkey, it has had much difficulty arranging foreign financing and investment. It remains heavily dependent on agriculture and government service, which together employ about half of the work force. To compensate for the economy's weakness, Turkey provides grants and loans to support economic development. Ankara provided $200 million in 2002 and pledged $450 million for the 2003-05 period. Future events throughout the island will be highly influenced by the outcome of negotiations on the UN-sponsored agreement to unite the Greek and Turkish areas.
