Abstract

To ensure their continuing integrity, the state of pipelines and cables needs to be monitored regularly. Divers, towfish ore remotely operated underwater vehicles (ROVs), which are traditionally used for cable & pipeline inspection, are time and human resources intensive. On the other hand, autonomous underwater vehicles (AUVs) represent a tool with great benefits. Therefore, a reliable localization and robust tracking system is required and it is the focus of this paper. The developed system will be tested for its performance in different pipeline layout scenarios.

Abstract

Between 2000 and 2005, infrastructure contributed less than 1 percentage point to the Central African Republic's annual per capita GDP growth, despite substantial spending in the road sector. Raising the country's infrastructure endowment to that of the region's middle-income countries could boost annual growth by about 3.5 percentage points. The CAR has made significant progress in the transport, water, power, and information and communications technology (ICT) sectors. But the high cost of fuel, which raises transportation and energy costs, has been a vexing issue across all infrastructure sectors. The CAR's most pressing infrastructural challenge lies in the transport sector, which relies heavily on neighboring countries and could benefit from improved road conditions and enhanced performance at the port of Douala in Cameroon. In the power sector, the country suffers from a deteriorating infrastructure stock that it can no longer afford to maintain, and an inefficient and unreliable power supply. Additional challenges include a need for improved infrastructure in the water and sanitation and ICT sectors. Addressing the CAR's infrastructure challenges will require sustained expenditure of $346 million per year over the next decade. The nation already spends around $134 million per year on infrastructure, with $37 million a year lost to inefficiencies of various kinds. If those inefficiencies were fully eliminated, the country's annual infrastructure funding gap would be $183 million per year. Improvements in funding, coupled with the prospect of an economic rebound and prudent policies, could lift the country from its fragile state back to and beyond the prosperity standards it once enjoyed.

Abstract

This study is a product of the Africa Infrastructure Country Diagnostic (AICD), a project designed to expand the world's knowledge of physical infrastructure in Africa. The AICD provides a baseline against which future improvements in infrastructure services can be measured, making it possible to monitor the results achieved from donor support. It also offers a solid empirical foundation for prioritizing investments and designing policy reforms in Africa's infrastructure sectors. The AICD is based on an unprecedented effort to collect detailed economic and technical data on African infrastructure. The project has produced a series of original reports on public expenditure, spending needs, and sector performance in each of the main infrastructure sectors, including energy, information and communication technologies, irrigation, transport, and water and sanitation. The focus of the AICD country reports is on benchmarking sector performance and quantifying the main financing and efficiency gaps at the country level. These reports are particularly relevant to national policy makers and development partners working on specific countries. This report presents the key AICD findings for Kenya, allowing the country's infrastructure situation to be benchmarked against that of its African peers. Given that Kenya is a relatively well-off low-income country that aspires to become a middle-income country, two sets of African benchmarks will be used to evaluate Kenya's situation. Detailed comparisons will also be made with immediate regional neighbors in the East African community. Document type: Book

Abstract

Infrastructure contributed 0.6 percentage points to Ethiopia's annual per capita gross domestic product (GDP) growth over the last decade. Raising the country's infrastructure endowment level to that of the region's middle-income countries could lift annual growth by an additional 3 percentage points. This will represent a significant boost over the growth performance of the mid-2000s, which averaged around 5 percent. The Africa Infrastructure Country Diagnostic (AICD) has collected and analyzed extensive infrastructure data for more than 40 Sub-Saharan countries, including Ethiopia. The results are presented in reports on various infrastructure sectors Information and Communication Technologies (ICT), irrigation, power, transport, water and sanitation and policy areas, including investment needs, fiscal costs, and sector performance. This country report presents the key AICD findings for Ethiopia. This will allow its infrastructure situation to be benchmarked against that of other African nations that, like Ethiopia, are low-income countries, with particular emphasis on immediate regional neighbors in East Africa. Several methodological issues should be borne in mind. First, the cross country nature of the data collection creates an inevitable time lag. The period covered by the AICD runs from 2001 to 2006. Most technical data are presented for 2006 (or the most recent year available), while financial data typically are averaged over the available period to smooth out the effect of short term fluctuations. Second, cross country comparisons require standardization of the indicators and the analysis to ensure consistency. Therefore, some of the indicators may be slightly different from those that are routinely reported and discussed at the country level. During the 2000s, Ethiopia's annual economic growth has averaged 4.8 percent, compared with only 0.5 percent in the previous decade. Notwithstanding this improvement, current annual growth levels still fall short of the sustained 7 percent needed to meet the Millennium Development Goals. Improved structural and stabilization policies generated an estimated 4.2 percent of Ethiopia's improved per capita growth performance during the 2000s, and improvements in the country's infrastructure platform over that period contributed up to 0.6 percentage points to growth. This was due almost entirely to the introduction of mobile telephony in Ethiopia. Simulations suggest that if Ethiopia's infrastructure platform could be improved to the level of the African leader, Mauritius, annual per capita growth rates could increase by 3.8 percent. This potential impact would come equally from improvements to transport, power, and ICT infrastructure. Document type: Book

Abstract

Infrastructure contributed 1.3 percentage points to Burkina Faso's annual per capita gross domestic product (GDP) growth over the past decade, much of it due to improvements in information and communication technology (ICT). Raising the country's infrastructure endowment to that of the region's middle-income countries (MICs) could boost annual growth by more than 3 percentage points per capita.Today, Burkina Faso's infrastructure indicators look relatively good when compared with other low-income countries (LICs) in Africa. Burkina Faso has made significant progress in developing its infrastructure in recent years. The rapid modernization of the ICT sector, around 60 percent of the population lives within range of a global system for mobile communications (GSM) cell-phone signal. The expansion of safe water and sanitation technologies in urban areas since the late 1990s and the establishment of a system for funding road maintenance (by reducing the cost of road travel) should pay long-term dividends to the economy. The Africa Infrastructure Country Diagnostic (AICD) has gathered and analyzed extensive data on infrastructure across almost all African countries, including Burkina Faso. The results have been presented in reports covering different areas of infrastructure including ICT, irrigation, power, transport and water and sanitation and various policy areas, including investment needs, fiscal costs, and sector performance.
