The literature gives two explanations for contractors' reluctance to adopt labor-based methods. First, contractors believe the cost of learning this new technology is high. Programs designed to promote labor-based methods have always included subsidized training to address this problem. This study argues that focusing on training often diverts attention away from more substantive problems inherent in adopting labor-based methods.
There are over one and a half million km of roads in Sub-Saharan Africa (SSA), including 554,000 km of main roads. Almost without exception, these roads are managed by bureaucratic government roads departments. The roads carry 80 to 90 percent of the region's passenger and freight traffic, absorb 5 to 10 percent of central government recurrent budgets and 10 to 20 percent of their development budgets.
The review presents an overview of the road sector in the seven UDEAC countries and in the Democratic Republic of Congo. It examines the adequacy of the infrastructure services as well as the efforts to improve financing and management and, thus, the sustainability of service and efficiency. The Central African Republic and Chad are the two truly landlocked countries in the region. However, the Democratic Republic of Congo also faces many of the same problems because of its vast land area and the narrow outlet to the Atlantic Ocean in the west.
