Publication Mali's Infrastructure : A Continental Perspective(2011-06-01)Despite external shocks, Mali's economy grew by 5.3 percent per year between 2003 and 2006, driven primarily by the telecommunications sector. But Mali's landlocked condition, together with the uneven distribution of population and economic activities between the arid north and the much richer south, defy the country's ability to sustain this pace of growth. Mali depends heavily on regional infrastructure and transport corridors. A strategic focus on regional integration has paid off, and critical institutional decisions are bringing many positive developments. But Mali still faces infrastructure challenges, the starkest of which lies in the power sector. The cost of producing power in Mali is among the highest in the region, with the result that only around 17 percent of the population has access to electricity, much lower than in other low-income African countries. The water and sanitation sectors also represent a challenge, as the nation works to separate the power and water-and-sanitation functions of EDM, the multisector utility. Mali spent about $555 million per year on infrastructure during the late 2000s. A total of $200 million is lost annually to inefficiencies. Assessing spending needs against existing spending and potential efficiency gains leaves an annual funding gap of $283 million per year.Mali will likely need more than a decade to reach the illustrative infrastructure targets outlined in this report. Under business-as-usual assumptions for spending and efficiency, it would take over 50 years for Mali to reach these goals. Yet with a combination of increased finance, improved efficiency, and cost-reducing innovations, it should be possible to reduce that time to 15 years.Publication Cape Verde’s Infrastructure : A Continental Perspective(2011-06-01)Cape Verde stands out in West Africa as a country whose economic geography poses major and unique challenges for infrastructure development. Its small population of half a million people is spread across a nine-island archipelago. The islands need complementary infrastructure in terms of roads, water, transport, ports, power, and ICT. Cape Verde already has well-developed infrastructure networks. Road density is relatively high, and most of the national network is paved. Almost all islands have port and airport facilities. Around 70 percent of the population has power and utility water. Indicators for ICT coverage -- penetration, bandwidth, submarine cable, private sector participation -- are relatively good. Nevertheless, prices for all services are exceptionally high. The quality of services is often deficient. At least half of the national road network is in poor condition; power supply is unreliable; and half of the population receives water from standposts. Cape Verde devotes around $147 million per year to infrastructure (almost 15 percent of GDP), among the highest levels of infrastructure spending on the continent. Some $50 million of that is lost each year to operations inefficiencies and underpricing. The country's main challenges are to improve infrastructure management and reduce high costs of services.Publication Cape Verde's Infrastructure(World Bank, Washington, DC, 2010-08)The Africa Infrastructure Country Diagnostic (AICD) has gathered and analyzed extensive data on infrastructure in more than 40 Sub-Saharan countries, including Cape Verde. The results have been presented in reports covering several sectors—ICT, irrigation, power, transport, water and sanitation— and various policy areas, including investment needs, fiscal costs, and sector performance. This report presents the key AICD findings for Cape Verde, allowing the country’s infrastructure situation to be benchmarked against that of its African peers. Given that Cape Verde is a relatively well- off middle-income country, its performance will be benchmarked against that of other middle-income countries in Africa. Detailed comparisons will also be made with immediate regional neighbors in the Economic Community of West African States (ECOWAS), and where relevant, with other island states that face a similar set of infrastructure challenges.Publication Mali Infrastructure(World Bank, Washington, DC, 2011-06)In recent years Mali's economy has grown steadily at a rate of more than 5 percent per year, driven by developments in gold mining, cereal harvests, and telecommunications. Mali's landlocked condition, together with its very uneven distribution of both population and economic activities between the arid north and the much richer south, challenge the country's ability to sustain this pace of growth. These two aspects define and challenge Mali's development and the infrastructure agendas. The country's strategic focus on the regional agenda has paid off to date, and critical institutional decisions are bringing many positive developments. More than 80 percent of Mali's segments of the West Africa road corridors are maintained in good or fair condition, giving the principal production areas of the south alternative access to the deep-water ports of Dakar, Adidjan, Takoradi, Tema, and Lome. Air transport security has improved, supported by the refurbishment of local airports, including Bamako airport, and the restructuring of Mali's Civil Aviation Authority to increase its autonomy and guarantee harmonization of air transportation rules across West Africa. Mali has also successfully liberalized its mobile telephone markets, with access approaching 40 percent in 2008. Roaming agreements and cross country competition have kept mobile prices low. Access to electricity in Mali more than doubled in the last decade, helped by the introduction of an apparently successful program for rural electrification (AMADER) that widened access to more than 36,000 rural households.Publication Liberia's Infrastructure(World Bank, Washington, DC, 2010-03)Liberia's 14-year civil war left much of the country's infrastructure shambles. The country's 170 megawatt power generation capacity and national grid were completely destroyed. In Monrovia, just 0.1 percent of households had access to electricity. According to the 2008 National Census, access to piped water fell from 15 percent of the population in 1986 to less than 3 percent in 2008. The national road network was left in severe disrepair. Peace brought many positive developments. The Freeport of Monrovia is now privately managed and has resumed normal operations. Essential rehabilitation work has been carried out, and the port's performance now matches that of neighboring ports along the West African coast. Liberia has also successfully liberalized its mobile telephone markets, with access surging to 40 percent in 2009, at some of the lowest prices in Africa. Despite the potential for private investment, Liberia will likely need more than a decade to reach the illustrative infrastructure targets outlined in this report. Under business-as-usual assumptions for spending and efficiency, it would take at least 40 years for Liberia to reach these goals. Yet with a combination of increased finance, improved efficiency, and cost-reducing innovations, it should be possible to significantly reduce that time.

Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication Sourcebook on the Foundations of Social Protection Delivery Systems(Washington, DC: World Bank, 2020-07-30)The Sourcebook synthesizes real-world experiences and lessons learned of social protection delivery systems from around the world, with a particular focus on social and labor benefits and services. It takes a practical approach, seeking to address concrete “how-to” questions, including: How do countries deliver social protection benefits and services? How do they do so effectively and efficiently? How do they ensure dynamic inclusion, especially for the most vulnerable and needy? How do they promote better coordination and integration—not only among social protection programs but also programs in other parts of government? How can they meet the needs of their intended populations and provide a better client experience? The Sourcebook structures itself around eight key principles that can frame the delivery systems mindset: (1) delivery systems evolve over time, do so in a non-linear fashion, and are affected by the starting point(s); (2) additional efforts should be made to “do simple well”, and to do so from the start rather than trying to remedy by after-the-fact adding-on of features or aspects; (3) quality implementation matters, and weaknesses in the design or structure of any core system element will negatively impact delivery; (4) defining the “first mile” for people interface greatly affects the system and overall delivery, and is most improved when that “first mile” is understood as the weakest link in delivery systems); (5) delivery systems do not operate in a vacuum and thus should not be developed in silos; (6) delivery systems can contribute more broadly to government’s ability to intervene in other sectors, such as health insurance subsidies, scholarships, social energy tariffs, housing benefits, and legal services; (7) there is no single blueprint for delivery systems, but there are commonalities and those common elements constitute the core of the delivery systems framework; (8) inclusion and coordination are pervasive and perennial dual challenges, and they contribute to the objectives of effectiveness and efficiency.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.
