What three major obstacles impede sub-Saharan African access to world markets?

What will be an ideal response?

Countries of Sub-Saharan Africa face three main obstacles to access world markets. First, geography is a major factor. Access across national boundaries is difficult for landlocked countries and is made more difficult by conflict. Second, local government policies discriminate against agriculture in favor of urban priorities. Third, industrialized countries promote policies that protect their agricultural markets. Policies such as trade barriers and subsidies blocked access to markets for farmers in sub-Saharan African countries, and the sale of food surpluses by industrialized countries distorted food prices.
