Abstract
This report aims to enhance the understanding of the priorities, needs, and solutions for improving air quality (AQ) in Central Asia (CA) through local action and regional collaboration. It focuses on key components of holistic air quality management (AQM): evidence-based analytics to identify the main sources of air pollution in CA, application of modern tools to assess the impact of cost-effective measures to improve AQ, assessment of the institutional and governance setup for AQM in CA with recommendations to strengthen it, and approaches to financing AQ improvement. Given the lack of comprehensive systematic and validated emission inventories of all PM2.5 precursor emissions, the technical assessment employs the regional emission inventory of the Greenhouse Gas - Air Pollution Interactions and Synergies (GAINS) model. Input data were updated for this study based on recent energy statistics and relevant national surveys. This report addresses emissions and the regional transboundary flows of pollution between Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan. Subsequently, the resulting PM2.5 concentrations in ambient air throughout CA were computed with the atmospheric chemistry and transport calculations of the GAINS model. Employing the source apportionment results of the GAINS model, the analysis then examines the contributions to PM2.5 population exposure. The report also presents source apportionment analyses for important air pollution hot spots in CA: Dushanbe (Tajikistan), Bishkek (the Kyrgyz Republic), Tashkent (Uzbekistan), Samarkand (Uzbekistan), Astana, and Almaty (Kazakhstan).

Publication Cleaner Transport Fuels for Cleaner Air in Central Asia and the Caucasus(Washington, DC, 2001-08)Combating pollution needs to be based on standards supported by enforced regulatory, and physical infrastructure, not always in place in countries in transition from central planning to a market economy. Policymakers in the Central Asia and the Caucus region, however, are recognizing the need for such steps against pollution, demonstrated by their commitment to phase out lead from gasoline. To support these efforts, the Bank undertook a regional study on cleaner transport fuels for urban quality improvement in the region, recognizing that fuel quality improvements should be linked to broader air quality management, to ensure cost-effectiveness, and in addressing these issues, it is therefore possible to build on economies of scale, avoid duplications, allow the transfer of experience, and facilitate intra-regional trade in petroleum products. This lead to this study's observations, and recommendations. The establishment of continuous monitoring of the "classical" pollutants, should permit comparison with international standards, by monitoring fine particles, airborne lead, and ground-level ozone. In turn, facilities with diagnostic equipment, and qualified technicians should be available, including vehicle registration systems. It is recommended that gasoline lead should be eliminated by 2005, sulfur in gasoline should be limited by 2015, benzene reductions should be phased out, and instead introduce the acceptable diesel sulfur specifications, and standards as in developed countries. Considerations should include the installation of isomer units; reevaluation on the role of refineries in gasoline production; and, fuel-quality specifications in privatization biding documents, should ensure predictability of regulations.Publication Strengthening Analysis for Integrated Water Resources Management in Central Asia(Washington, DC, 2013-09)This report outlines a 3-year program to upgrade the knowledge platform for managing water resources in Central Asia. Its ultimate purpose is to enhance the ability of all countries to engage in evidenced- based dialogue on water and energy management. It focuses on regional actions, linking all five countries plus Afghanistan, but recognizes the essential role of national initiatives. It covers the core elements of a modern decision support system and, based on extensive consultations, supports a change in accessing, developing, and sharing information and analysis. The intended outcomes of the road map are to: (i) establish a knowledge platform that is accepted by countries as a basis for cooperative actions; (ii) enhance capacity and knowledge sharing at the national and regional levels; and (iii) directly improve management of water at national and transboundary scales.Publication Weather and Climate Services in Europe and Central Asia : A Regional Review(Washington, DC : World Bank, 2008)This paper reviews the status of weather and climate services in Europe and Central Asia (ECA).Worldwide, the accuracy and value of weather and climate services are rising, bringing great economic benefits. However, many National Meteorological and Hydrological Services (NMHSs) in Europe and Central Asia are in decline. As a result, these potential gains are often missed. Much more could be done to mitigate weather disasters, support the productivity of smallholding and commercial agriculture, conserve energy, and promote safe aviation and transport by road and rail. Although NMHS capacity deficiencies are serious, they could be significantly remedied by relatively modest but sustained investments. Economic assessments indicate substantial benefit-to-cost ratios for such initiatives. A strategy for NMHS service improvement requires assessment of national climate, user needs, NMHS status and provision of services, and the economic benefits of an upgrade to weather and climate services. recommendations for agency modernization should include (a) a prioritized plan for improving data delivery to national users, (b) identification of the highest-priority infrastructure investments, and (c) a reasonable phasing plan for overall modernization.Publication Clean Air and Healthy Lungs : Enhancing the World Bank's Approach to Air Quality Management(World Bank, Washington, DC, 2015-02)This report specifically deals with air pollution, which was reported, by the World Health Organization (WHO), as the single largest environmental health risk globally in 2012 (WHO, 2014a). Air pollution from outdoor and household sources jointly account for more than 7 million deaths (3.7 million from ambient air pollution and 4.3 million from household air pollution). The following sections of this chapter present the objectives of, and key aspects of the institutional context for, this report followed by an examination of some of the major drivers of deteriorating ambient air quality in developing countries; air pollution sources and impacts; and the status of air quality management in developing countries. Chapter two presents the results of a desk-based portfolio review of World Bank projects that are relevant to reduction of air pollution. This is followed, in chapter three, by an examination of case studies of World Bank projects whose objectives include addressing ambient air pollution, highlighting good practices and lessons for future work of the Bank in supporting clients. Chapter four presents possible approaches for enhancing future Bank support in helping clients to improve air quality and reduce the associated adverse health outcomes. Chapter five presents overall conclusions and recommendations.Publication Urban Air Quality Management : Coordinating Transport, Environment, and Energy Policies in Developing Countries(Washington, DC: World Bank, 2001-09)Transport-related air pollution is increasingly contributing to environmental health risks in many developing country cities. The social costs of poor urban quality can be significant, making this issue an immediate priority. Long-term measures for dealing with the problem include urban planning, and traffic demand management. This paper however, focuses primarily on cost-effective measures, that are feasible to implement, and that can bring measurable results in the short to medium term. There is a tendency in the environment sector, to focus narrowly on controlling emissions by importing the best available technology. Cost-effective, and sustainable solutions, however, require much broader approaches. In developing countries, improving air quality is not simply a matter of importing advanced technologies, while, choices concerning feasibility, sequencing, and timing of pollution reducing measures, have serious fiscal, and economic consequences. Thus the guiding principle for selection of strategies, should be the balancing of costs, benefits, and technical, and institutional feasibility. Monitoring, and enforcement are essential , but countries need to know the nature, and magnitude of the pollution problem, to determine the speed, and rigor with which policies should be implemented. Furthermore, pollution enforcement measures have implications on petroleum taxation, and on the tariff regime, as well as for traffic management.

Publication State of Social Protection Report 2025(Washington, DC: World Bank, 2025-04-07)Social protection goes well beyond cash transfers; it includes policies and programs that bridge skill, financial, and information gaps, aiding people in securing better jobs. The three pillars of social protection—social assistance, social insurance, and labor market programs—support households and workers in handling crises, escaping poverty, facing transitions, and seizing employment opportunities. But despite a substantial expansion over the past decade, 2 billion people remain uncovered or inadequately covered across low- and middle-income countries. Drawing from administrative and household survey data from the World Bank’s Atlas of Social Protection Indicators of Resilience and Equity (ASPIRE), the "State of Social Protection Report 2025: The 2-Billion-Person Challenge" documents advances and challenges to strengthening social protection and labor systems across low- and middle-income countries, analyzing the evolution of expenditure, coverage, and adequacy of support. This report details four policy action areas governments can embrace to maximize the benefits of adequate social protection for all: extending social protection to those in need; strengthening the adequacy of social protection support; building shock-proof social protection systems; and optimizing social protection financing. The report discusses how the path of reforms will depend on country context, capacity, and fiscal space. The rising frequency of shocks and crises calls for major investments in the adaptability and preparedness of social protection and labor systems. Amid a world in transition, social protection is more important and necessary than ever.Publication World Bank Annual Report 2024(Washington, DC: World Bank, 2024-10-25)This annual report, which covers the period from July 1, 2023, to June 30, 2024, has been prepared by the Executive Directors of both the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA)—collectively known as the World Bank—in accordance with the respective bylaws of the two institutions. Ajay Banga, President of the World Bank Group and Chairman of the Board of Executive Directors, has submitted this report, together with the accompanying administrative budgets and audited financial statements, to the Board of Governors.Publication Cities’ Partnership Initiative(Washington, DC: World Bank, 2025-04-24)Sustainable urban development is one of the key areas of development policy in Poland, which is in line with global trends. Sustainable urban development requires an integrated approach that takes into account the complexity and dynamics of phenomena and processes taking place in the urban environment. Meeting the challenges of urban development requires, on the one hand, a steady increase in the capacity of cities to plan and implement development projects, and on the other hand, a favorable regulatory and financial framework and support instruments that are an adequate response to the needs of urban centers. The Cities’ Partnership Initiative (CPI) is a flagship project of the Ministry of Development Funds and Regional Policy of Poland (MDFRP) aimed at supporting sustainable urban development. This final report is the third product of the Reimbursable Advisory Service Agreement on Sustainable Urban Development - Cities’ Partnership Initiative concluded between the MDFRP and the World Bank on January 28, 2022. The report summarizes the project work, including the results of the work of 30 CPI-participating cities, and presents conclusions and recommendations on the three thematic networks and the CPI formula itself.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 Latin America and the Caribbean Economic Review, April 2025: Organized Crime and Violence in Latin America and the Caribbean(Washington, DC: World Bank, 2025-04-28)The Latin America and Caribbean region faces a very different outlook from what was foreseen six months ago. Despite continued progress on reducing inflation, LAC continues to grow more slowly than any other region of the world and increasing its dynamism and job creation potential faces new and daunting challenges. First, higher and more persistent inflation than anticipated in the advanced countries has slowed global interest rate declines which constrains regional monetary authorities’ ability to loosen monetary policy. Second, higher interest payments on debt consume an increasing share of government revenue impeding progress on reducing deficits and creating fiscal space for necessary public investment. Third, rising tariffs have driven up uncertainty around the nature of the global trade order, threaten market access for exports, and call into question the nearshoring project. Fourth, increased return migration will, in some cases, stress local labor markets and dampen remittances. Fifth, organized crime, and the violence that accompanies it continues to expand, reducing the quality of life of citizens, dampening economic growth, and undermining the integrity of public institutions. Progress on the fiscal front, as well as continued productivity related reforms to make the region more able to negotiate a changing environment are needed.
