Publication(World Bank, Washington, DC, 2008-02) Banerjee, Sudeshna ; Wodon, Quentin ; Diallo, Amadou ; Pushak, Taras ; Uddin, Helal ; Tsimpo, Clarence ; Foster, VivienAfrica lags well behind other developing regions in infrastructure access. The limited gains of the 1990s have not increased much in the 2000s. There is clear evidence that many countries are failing to expand services fast enough to keep ahead of rapid demographic growth and even faster urbanization. As a result, if present trends continue, Africa is likely to lag even further behind other developing regions, and universal access will be more than 50 years away in many countries. However, there is variation in performance across countries, even within the low and middle income brackets. A significant number of countries have succeeded in increasing the number of people who have access to water, electricity, and sanitation, by an annual average of 5-10 percent. Further investigation is warranted to explain what determines the superior performance of these countries.
Measuring Trends in Access to Modern Infrastructure in Sub-Saharan Africa : Results from Demographic and Health Surveys(World Bank, Washington, DC, 2007-10) Banerjee, Sudeshna ; Diallo, Amadou Bassirou ; Wodon, QuentinA recent study for sub-Saharan Africa by Banerjee et al. (2007) uses Demographic and Health Surveys (DHS) from 22 countries that have conducted at least two such surveys between 1990 and 2005 in order to collect comparable information across countries on access to modern and alternative infrastructure services over time. In addition to national, urban, and rural trends in access, the study includes a distributional analysis of how access rates have evolved since 1990. That is, households are divided into five quintiles of population according to their level of wealth, with wealth defined using a principal components analysis. The objective of this note is to provide a summary of key findings from the study regarding access trends to electricity, piped water, flush toilets, and landline telephones over the period 1990-2005.
Publication(Washington, DC: World Bank, 2015-02-05) Banerjee, Sudeshna Ghosh ; Romo, Zayra ; McMahon, Gary ; Toledano, Perrine ; Robinson, Peter ; Pérez Arroyo, InésAfrica needs power - to grow its economies and enhance the welfare of its people. Power for all is still a long distance away - two thirds of the population remains without electricity and enterprises rank electricity as a top constraint to doing business. This sub-optimal situation coexists while vast energy resources remain untapped. One solution to harness these resources could be to tap into the concept of anchor load. Mining industry lends itself to the concept of anchor load as it needs power in large quantity and reliable quality to run its processes. Underpinned by a comprehensive database of mining projects between 2000 and 2020, this report explores the potential and challenges of using mining demand for power as anchor load for national power system development and expansion of electrification. This report finds that mining demand can indeed be a game-changer - an opportunity where policymakers and international community can make a difference in tapping the enormous mineral wealth of Africa for the benefit of so many people. The utilities would benefit from having mining companies as creditworthy consumers that facilitate generation and transmission investments producing economies of scale needed for large infrastructure projects, benefiting all consumers in the system. The mines would benefit from grid supply - typically priced much lower than self-supply - which allows them to focus on their core business, greatly enhancing their competitiveness. The country would benefit from more exports and tax revenues from mines, more job opportunities in local firms selling goods and services to the mines, and a higher GDP. The report estimates that mining demand for power can triple since 2000 going upto 23 GW in 2030. While South Africa will continue to be the dominant presence in mining landscape, its importance will reduce and other countries, primarily in Southern African region, will emerge as important contributers of mining demand for power. Simulations in countries with minimal power-mining interface suggests that bringing this demand explicitly into the power planning process can ensure more investments in both grid and off-grid power systems and potentially superior service delivery outcomes for mines as well as communities. These opportunities can also be attractive investment destinations for private sector. However, there are also risks and institutional roadblocks in power-mining integration - addressing many of them and employing risk mitigation mechanism are within the control of policymakers.
Publication(World Bank, Washington, DC, 2008-06) Banerjee, Sudeshna ; Skilling, Heather ; Foster, Vivien ; Briceno-Garmendia, Cecilia ; Morella, Elvira ; Chfadi, TarikWith only 56 percent of the population enjoying access to safe water, Sub-Saharan Africa lags behind other regions in terms of access to improved water sources. Based on present trends, it appears that the region is unlikely to meet the target of 75 percent access to improved water by 2015, as specified in the Millennium Development Goals (MDG). The welfare implications of safe water cannot be overstated. The estimated health and time-saving benefits of meeting the MDG goal are about 11 times as high as the associated costs. Monitoring the progress of infrastructure sectors such as water supply has been a significant by-product of the MDG, and serious attention and funding have been devoted in recent years to developing systems for monitoring and evaluating in developing countries. Piped water reaches more urban Africans than any other form of water supply-but not as large a share as it did in the early 1990s. The most recent available data for 32 countries suggests that some 39 percent of the urban population of Sub-Saharan Africa is connected to a piped network, compared with 50 percent in the early 1990s. Analysis suggests that the majority of those who lack access to utility water live too far away from the distribution network, although some fail to connect even when they live close by. Water-sector institutions follow no consistent pattern in Sub-Saharan Africa. Where service is centralized, a significant minority has chosen to combine power and water services into a single national multi-utility urban water sector reforms were carried out in the 1990s, with the aim of creating commercially oriented utilities and bringing the sector under formal regulation. One goal of the reforms was to attract private participation in the sector.
Provision of Water to the Poor in Africa : Experience with Water Standposts and the Informal Water Sector( 2010-07-01) Keener, Sarah ; Luengo, Manuel ; Banerjee, SudeshnaStandpipes that dispense water from utilities are the most common alternatives to piped water connections for poor customers in the cities of Sub-Saharan Africa. Fifty-five percent of the unconnected urban population relies on standpipes as their first water source. Other informal water providers include household resellers and a variety of water tankers and vendors, which are the first water source of 1 percent and 3 percent of the urban population, respectively. In the cities studied, the percentage of unconnected households ranges from 12 percent to 86 percent of the population. The percentage of unconnected people covered by standpipes is substantially higher for countries with higher rates of household connection, while the percentage of unconnected people covered by water tankers or water vendors is higher for countries with lower rates of household connection. Water prices in the informal market are much higher than for households with private connections or yard taps. Although standpipes are heavily subsidized by utilities, the prices charged by standpipe operators are closely related to the informal water reseller price. Standpipe management models also affect the informal price of water. For example, the shift from utilities management to delegated management models without complementary regulation or consumer information has often led to declines in service levels and increased prices. Standpipes are not the only or even the most efficient solution in peri-urban areas. Programs that promote private household connections and arrangements that improve pricing and services in the household resale market should also be considered by policy makers.
Is Low Coverage of Modern Infrastructure Services in African Cities due to Lack of Demand or Lack of Supply?( 2009-03-01) Wodon, Quentin ; Banerjee, Sudeshna ; Diallo, Amadou Bassirou ; Foster, VivienA majority of sub-Saharan Africa s population is not connected to electricity and piped water networks, and even in urban areas coverage is low. Lack of network coverage may be due to demand or supply-side factors. Some households may live in areas where access to piped water and electricity is feasible, but may not be able to pay for those services. Other households may be able to afford the services, but may live too far from the electric line or water pipe to have a choice to be connected to it. Given that the policy options for dealing with demand as opposed to supply-side issues are fairly different, it is important to try to measure the contributions of both types of factors in preventing better coverage of infrastructure services in the population. This paper shows how this can be done empirically using household survey data and provides results on the magnitude of both types of factors in explaining the coverage deficit of piped water and electricity services in urban areas for a large sample of African countries.
Publication( 2009-03-01) Banerjee, Sudeshna ; Diallo, Amadou ; Foster, Vivien ; Wodon, QuentinHousehold surveys have long been used to estimate poverty and inequality trends, as well as trends in education and health indicators, but they have not been used to the same extent to assess trends in the access to or coverage of modern infrastructure services. In this paper, we use Demographic and Health Surveys from a larger sample of sub-Saharan African countries in order to collect comparable information across countries on coverage of piped water, flush toilets, electricity, and landline telephones over time. The results suggest that coverage rates for electricity, flush toilets have improved slightly over the last decade. Coverage of piped water has declined, at the same time as coverage of landline (as well as cellular) telephone has increased rapidly. The decline has been primarily in the urban areas while the infrastructure coverage has either increased or remained stable in rural Africa. For all four services, among the poorest households coverage remains virtually inexistent. If business as usual continues, it would take a very long time to reach universal or widely shared coverage even in countries where coverage has improved. These results point to the need to increase efforts by governments and international community to progressively increase access to modern infrastructure services in Africa.
Publication(World Bank, 2011-03-09) Banerjee, Sudeshna Ghosh ; Morella, Elvira ; Foster, Vivien ; Briceño-Garmendia, CeciliaThe Africa Infrastructure Country Diagnostic (AICD) has produced continent-wide analysis of many aspects of Africa's infrastructure challenge. The main findings were synthesized in a flagship report titled Africa's Infrastructure: a time for transformation, published in November 2009. Meant for policy makers, that report necessarily focused on the high-level conclusions. It attracted widespread media coverage feeding directly into discussions at the 2009 African Union Commission Heads of State Summit on Infrastructure. Although the flagship report served a valuable role in highlighting the main findings of the project, it could not do full justice to the richness of the data collected and technical analysis undertaken. There was clearly a need to make this more detailed material available to a wider audience of infrastructure practitioners. Hence the idea of producing four technical monographs, such as this one, to provide detailed results on each of the major infrastructure sectors, information and communication technologies (ICT), power, transport, and water, as companions to the flagship report. These technical volumes are intended as reference books on each of the infrastructure sectors. They cover all aspects of the AICD project relevant to each sector, including sector performance, gaps in financing and efficiency, and estimates of the need for additional spending on investment, operations, and maintenance. Each volume also comes with a detailed data appendix, providing easy access to all the relevant infrastructure indicators at the country level, which is a resource in and of itself.
