Abstract
This primer is concerned with energy use and efficiency of network-based water supply and wastewater treatment in urban areas. It focuses on the supply side of the municipal water cycle, including the extraction, treatment, and distribution of water, and collection and treatment of wastewater-activities which are directly managed by Water and Wastewater Utilities (WWUs). The main challenges to scaling up Energy Efficiency (EE) in municipal water and wastewater services stem from sector governance issues, knowledge gaps, and financing hurdles. Utility governance affects the overall performance of individual WWUs and influences decision making, incentives and actions for energy management. This is likely the most significant barrier to WWU EE in many developing countries. Addressing knowledge gaps requires efforts to systematize data collection, training, and capacity building at utilities, supported by local and national governments. Financing hurdles can be reduced by introducing dedicated EE funds to address large but disaggregated investment needs and by promoting third-party financing through energy/water savings performance contracts. This primer is part of Energy Efficient Cities Initiative's (EECI's) knowledge clearinghouse function to inform World Bank (WB) staff working in urban water supply and wastewater management, as well as in energy, about the opportunities and good practices for improving EE and reducing energy cost in municipal WWUs.

Publication Inclusive Green Growth in Latin America and the Caribbean(Washington, DC, 2013-01)Argentina has expanded the use of its portion of the Parana-Paraguay waterways system for the transportation of soy and other bulk commodities through an innovative tolling system that self-finances the dredging and maintenance of the rivers. Brazil, in turn, is pursuing a 'green trucking' strategy to improve efficiency of its cargo haulage industry, reduce petroleum usage, and curb pollution from trucking. For the entire hemisphere, the expansion of the Panama Canal will bring post-Panama vessels and introduce greater scale economies in shipping. The following sections of this paper provide a more detailed review of the sectoral objectives, challenges, and way forward in making Latin America and Caribbean (LAC) growth greener and more inclusive. It looks back over the achievements of the demand sectors of urban development and infrastructure services, energy, urban transport, and water and sanitation, as well as natural resources and rural development since Rio 1992. It highlights the achievements in those areas, and the ability of those accomplishments to establish a robust path for the region to inclusive green growth.Publication Thirsty Energy(World Bank, Washington, DC, 2013-06)The tradeoffs between energy and water have been gaining international attention in recent years as demand for both resources mount and governments continue to struggle to ensure reliable supply to meet sectoral needs. As almost all energy generation processes require significant amounts of water, and water requires energy for treatment and transport, these two resources are inextricably linked. This relationship is the energy-water nexus. Section one of this paper examines the existing models, literature, and management frameworks on the nexus, as it seeks to determine what gaps exist. Section two describes the water demands of power generation in order to identify potential areas of future uncertainty and delineate areas where integrated energy-water management may improve the reliability of operating power plants and the viability of schemes. Finally, section three describes possible solutions that may alleviate challenges resulting from the link between energy and water by improving energy efficiency and integrating water resources management into energy planning.Publication Botswana's Infrastructure : A Continental Perspective(2011-11-01)Infrastructure made a net contribution of just over two percentage points to Botswana'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 1.2 percentage points. Botswana has made significant infrastructure progress in recent years, spanning the transport, water and sanitation, power, and mobile telephony sectors. But the country still faces a number of important infrastructure challenges. The most pressing is in the power sector, where the country is economically and financially exposed to a lack of generation capacity and insufficient power supply, leaving the economy vulnerable to power price shocks and load shedding. Botswana's international transport connections and Internet connectivity also lag behind those of comparable countries. Botswana's overall resource envelope of $800 million per year surpasses its $785 million needs estimate. Nevertheless, it loses $68 million a year to inefficiencies and faces a funding gap of $305 million per year, entirely in the power sector, traceable to the quality of spending decisions. Botswana will be in a good position to meet its infrastructure goals if it can reduce inefficiencies, increase public-sector receipts, and attract more public funding.Publication Running Water in India's Cities : A Review of Five Recent Public-Private Partnership Initiatives(Washington, DC, 2014)India is home to more than 370 million people in urban areas. Historically, almost all water supply provision has been managed by the public sector through municipal or state-level departments or parastatals. Benchmarking initiatives show that coverage through piped water supply ranges between 55 percent and 89 percent in urban areas. Per capita availability is fairly high, at 90 to 120 liters per day, but no city yet offers continuous water supply. Daily supply averages four hours, with many cities alternating supply every other day. These challenges occur in a context of weak management systems and little data on existing assets, which makes it difficult to assess investment needs and time lines to improve service levels and operational efficiencies. While investment requirements are likely to be significant, it is recognized that investments alone will not be effective unless the country simultaneously addresses related issues such as complex and fragmented institutions with little accountability; lack of capacity to run utilities efficiently and meet performance standards; weak commercial orientation; interference in utility operations by external entities; and the absence of a regulatory framework focused on customer service and financial sustainability. In response to social issues, all contracts have proactively provided for service delivery options to consumers as well as tariff concessions (bulk supply to poor neighborhoods, fortnightly payment options, special tariff for group connections, and so forth). It will also be useful to explicitly state the subsidy that the city will bear for connecting poor consumers to the network. Explicit arrangements in the contract will allay apprehensions of urban poor as well as encourage the operator to connect the poor.Publication Running Water in India's Cities : A Review of Five Recent Public Private Partnership Initiatives(Washington, DC, 2014-01)India is home to more than 370 million people in urban areas. No city in the country meets the government's targets for continuous pressurized safe water with full coverage and full cost recovery. Groundwater sources are also being depleted putting severe constraints on economic development. To make up for unreliable services, households have invested significantly in alternate arrangements over the past three decades. Reliable estimates of asset condition and performance in Indian cities are difficult to establish, given the poor culture of documentation, data collection, and reporting. Data drawn from several benchmarking initiatives indicate the following: service delivery parameters are well below established norms, with coverage through piped water supply ranging between 55 percent and 89 percent, and while per capita availability is fairly high, at 90-120 liters per day, no city offers continuous water supply. Daily supply averages four hours, with many cities alternating supply every other day. These challenges occur in a context of limited data or data management capability and largely unknown conditions of existing assets, which present difficulties in assessing the costs and timelines involved in improving service levels and operational efficiencies. Moreover, the investments required are likely to be significant, particularly since most cities have seen little systematic investment in asset management and expansion over the years. Simultaneously, it is recognized that investments alone will not be effective in the context of complex and fragmented institutions with little accountability; lack of capacity to run utilities efficiently and meet performance standards; weak commercial orientation; interference in utility operations by external entities; and the absence of a regulatory framework focused on customer service and financial sustainability

Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.
