Despite general economic decline and power supply deficiencies, infrastructure made a modest net contribution of less than half a percentage point to Zimbabwe's improved per capita growth performance in recent years. Raising the country's infrastructure endowment to that of the region's middle-income countries could boost annual growth by about 2.4 percentage points. Zimbabwe made significant progress in infrastructure in its early period as an independent state. The country managed to put in place a national electricity network and establish regional interconnection in the power sector; to build an extensive network of roads for countrywide accessibility and integration into the regional transport corridors; to lay the water and sewerage system; and to make progress on building dams and tapping the significant irrigation potential. Unfortunately, at present the cross-cutting issue across all these sectors is Zimbabwe's inability to maintain and rehabilitate the existing infrastructure since the country became immersed in economic and political turmoil in the late 1990s. Neglect of all sectors due to the crisis has resulted in a generalized lack of new investment (in the power and water sectors in particular), and the accumulation of a huge rehabilitation agenda. Quality of service has declined across the board. The power system has become unjustifiably costly, inefficient, and unreliable. The condition of roads has deteriorated to the point that Zimbabwe became a bottleneck on the North-South transport corridor. Rural connectivity hardly exists. Failure to treat potable water, along with the deterioration of the water, sanitation, and garbage disposal systems, was responsible for the spread of cholera in 2008. By 2010 cholera affected most areas of the country and posed a health threat to neighboring countries. Looking ahead, Zimbabwe faces a number of important infrastructure challenges. Zimbabwe's most pressing challenges lie in the power and water sectors. Inefficient and unreliable power supply poses major risks to the economy, while the maintenance and upgrading of existing power infrastructure no longer looks to be affordable. At the same time, overhauling the water and sewerage system is imperative for curbing the public health crisis.

Upgrading infrastructure plays a critical role in the Republic of Congo's quest to diversify its economy and reduce poverty. It is also an important source of growth on its own. A cross-country statistical analysis conducted for this report shows that infrastructure contributed one-half of one percentage point to the Republic of Congo's per capita gross domestic product (GDP) growth annually from 2001 to 2006. However, if the country's infrastructure could be improved to the level seen in Mauritius, the leading country in Sub-Saharan Africa, it could contribute more than 3 percentage points to annual per capita growth. The Republic of Congo's power infrastructure is inadequate and inefficiently operated. The country lags well behind peer countries in generation capacity and electrification. The parts of the population not served by the grid face exorbitant costs. The government has responded to these issues with an ambitious investment plan. However, if new assets are to operate effectively, major inefficiencies in the power utility will also need to be addressed. The utility's transmission and distribution losses are 47 percent, more than double best-practice benchmarks, while the cost of overstaffing is 30 percent of utility revenue. Tariffs recover barely half the cost of service provision, even though full cost recovery will be affordable to the population. In the information and communication technology (ICT) sector, the Republic of Congo has made good progress in developing its mobile telephony market in recent years, with high levels of signal coverage. The cost of international connectivity is currently high, but it should fall once the country connects to the international submarine cable and completes its domestic fiber optic network. On the other hand, the physically dilapidated and financially depleted condition of the fixed-line telephone operator is becoming a constraint to raising Internet penetration. The Republic of Congo performs relatively well on service coverage in the water and sanitation sector. The country's access statistics are substantially ahead of those in its peer group, particularly with regard to piped water, stand-posts, and improved latrines. However, access to services is much greater in urban areas than in rural areas. Furthermore, under-pricing of water has hurt the financial soundness of the water utility, even though analysis suggests that cost recovery tariffs would be affordable to consumers.

Sustainable infrastructure development is vital for Africa's prosperity. And now is the time to begin the transformation. This volume is the culmination of an unprecedented effort to document, analyze, and interpret the full extent of the challenge in developing Sub-Saharan Africa's infrastructure sectors. As a result, it represents the most comprehensive reference currently available on infrastructure in the region. The book covers the five main economic infrastructure sectors-information and communication technology, irrigation, power, transport, and water and sanitation. Africa's infrastructure sectors lag well behind those of the rest of the world, and the gap is widening. Some of the main-policy-relevant-findings highlighted in the book include the following: infrastructure in the region is exceptionally expensive, with tariffs being many times higher than those found elsewhere. Inadequate and expensive infrastructure is retarding growth by 2 percentage points each year. Solving the problem will cost over US90 billion per year, which is more than twice what is being spent in Africa today.However, money alone is not the answer. Prudent policies, wise management, and sound maintenance can improve efficiency. There is the potential to recover an additional US17 billion a year from within the existing infrastructure resource envelope-simply by improving efficiency.Finally, the power sector and fragile states represent particular challenges. Even if every efficiency in every infrastructure sector could be captured, a substantial funding gap of 31 billion a year would remain. Nevertheless, the African people and economies cannot wait any longer. Now is the time to begin the transformation to sustainable infrastructure development.

Between 2000 and 2005 infrastructure made a contribution of 1 percentage point to Senegal's improved per capita growth performance, placing it in the middle of the distribution among West African countries during the period. Raising the country's infrastructure endowment to that of the region's middle-income countries (MICs) could boost annual growth by about 2.7 percentage points. Senegal has made significant progress in some areas of its infrastructure. In the transport sector, road standards are adequate and their quality average. Senegal has also strengthened the road institutional framework with the creation of the Second Generation Road Fund (FERA) and the Road Maintenance Executing Agency. It has also managed to have a toll road concession granted for the Dakar-Diamniadio Toll Highway. The tariffs in the railway sector are internationally competitive, and there has been improvement in the financial viability of ports. After Nigeria, the country stands as an emerging hub and a major player in air transport. Also, Senegal has managed to introduce private participation in electricity generation, and the unbundling of the electricity sector is under way even as the country actively participates in the regional power market. The country is on track to meet the Millennium Development Goals (MDGs) in improved water. In the information and communication technology (ICT) sector there has been an impressive expansion of the mobile and Internet markets. Senegal already spends around $911 million per year on infrastructure, equivalent to about 11 percent of its gross domestic product (GDP). Almost $312 million a year is lost to inefficiencies of various kinds, associated mainly with under-pricing in the power and water sectors, poor financial management of utilities, and inefficient allocation of resources across sectors. If Senegal could raise tariffs to cost-recovery levels and reduce operational inefficiencies in line with reasonable developing-country benchmarks, it could substantially boost its infrastructure sector.
