Cape Verde economy suffers from a poor natural resource base, including serious water shortages exacerbated by cycles of long-term drought. The economy is service-oriented, with commerce, transport, tourism, and public services accounting for about three-fourths of GDP. Cape Verde has rich fishing potential as it is located in the midst of fishing grounds, but the industry has yet to develop. Cape Verde annually runs a high trade deficit, financed by foreign aid and remittances from emigrants; remittances supplement GDP by more than 20%. Economic reforms are aimed at developing the private sector and attracting foreign investment to diversify the economy.
