Subsistence agriculture, together with forestry, remains the backbone of the economy of the Central African Republic (CAR), with more than 70% of the population living in outlying areas. The agricultural sector generates half of GDP. Timber has accounted for about 16% of export earnings and the diamond industry for 54%. Important constraints to economic development include the CAR's landlocked position, a poor transportation system, a largely unskilled work force, and a legacy of misdirected macroeconomic policies. Factional fighting between the government and its opponents remains a drag on economic revitalization, with GDP likely to contract in 2004. Distribution of income is extraordinarily unequal. Grants from France and the international community can only partially meet humanitarian needs.
