Abstract
This Good Practice Handbook is designed to provide guidance to practitioners on taking rigorous and consistent approaches to assess hydropower project impacts on downstream river ecosystems and people, and determine their Environmental Flows (EFlows) commitments. The Handbook outlines a good practice approach for integrating EFlows into hydropower projects, emphasizing the selection of context-appropriate EFlows Assessment methods. Its structure follows the main steps of this approach: 1. Understand the context of river functioning and the provision of ecosystem values and services into which EFlows will be introduced (Section 2); 2. Understand the potential downstream impacts associated with hydropower development (Section 3) and how these can be mitigated (Section 4); 3. Align ESIA and EFlows Assessments and ensure data sharing and good communication between the assessment teams (see Section 5); 4. Apply a context-appropriate EFlows Assessment method (Section 6); 5. Conduct a comprehensive and appropriate stakeholder engagement program leading to a decision on EFlows and other mitigation measures based on the outcome of the assessment (Sections 7 and 8); and 6. Prepare an Environmental Flow Management Plan (EFMP2; Section 9). It also provides the following: A logframe for integrating EFlows into hydropower plants (Section 10); and Case studies to illustrate the main concepts addressed in the Handbook (Section 11).

Publication A Guide for Local Benefit Sharing in Hydropower Projects(World Bank, Washington, DC, 2012-06)Local benefit sharing in hydropower projects can be defined as the systematic efforts by project proponents to sustainably benefit local communities affected by hydropower investments. Benefit sharing is a promising approach for implementing hydropower projects sustainably, and is emerging as a supplement to the requirements of compensation and mitigation. Benefit sharing can provide equitable development, sustainability, and smooth project implementation for hydropower development. For benefit sharing mechanisms to work, the key enabling conditions are government policies, the legal and regulatory framework, corporate social responsibility strategies of development companies, and the capacity of local communities. Stakeholder engagement is essential in initiating and designing benefit sharing programs. This guide provides some advice to task teams on how to design effective local benefit sharing mechanisms in hydropower projects. Benefit sharing arrangements would ensure that local communities have the opportunity to benefit directly from hydropower development, which will make hydropower projects more environmentally and socially sustainable. As a long-term arrangement, benefit sharing can facilitate local development. It can respond to unexpected environmental circumstances in the operation of dams to ensure local communities receive adequate benefits. Arrangements for the equitable sharing of benefits can offer scope for local communities and all other stakeholders to avoid conflicts and focus on creating synergies to maximize local development opportunities.Publication Environmental Flows in Water Resources Policies, Plans, and Projects : Case Studies(World Bank, Washington, DC, 2009-04)The overall goal of this report and the accompanying report summarizing the findings and recommendations, both based on the economic and sector work (ESW), is to advance the understanding and integration in operational terms of environmental water allocation into integrated water resources management. The specific objectives of the reports are the following: 1) document the changing understanding of environmental flows, both by water resources practitioners and by environmental experts within the Bank and in borrowing countries; 2) draw lessons from experience in implementing environmental flows by the Bank, other international development organizations with experience in this area, and a small number of developed and developing countries; 3) develop an analytical framework to support more effective integration of environmental flow considerations for informing and guiding: (a) the planning, design, and operations decision making of water resources infrastructure projects; (b) the legal, policy, institutional, and capacity development related to environmental flows; and (c) restoration programs; and 4) provide recommendations for improvements in technical guidance to better incorporate environmental flow considerations into the preparation and implementation of lending operations.Publication Good Dams and Bad Dams : Environmental Criteria for Site Selection of Hydroelectric Projects(World Bank, Washington, DC, 2003-11)This paper provides a simple, yet robust, methodology for comparing proposed hydroelectric project sites in terms of their expected negative environmental impacts, and relating these to power generation benefits. The paper also summarizes the environmental mitigation options for large dams. If properly implemented, these mitigation measures can effectively prevent, minimize, or compensate for many (though not all) of a hydroelectric project's negative impacts. Nonetheless, the most effective environmental mitigation measure is good site selection, to ensure that the proposed dam will cause relatively little damage in the first place. The paper presents quantitative indicators (using data that are relatively easy to obtain) for rating and ranking proposed new hydroelectric projects in terms of their likely adverse environmental impacts. Projects with a small reservoir surface area (relative to power generation) tend to be most desirable from both an environmental and social standpoint, in part because they minimize natural habitat losses as well as resettlement needs. In general, the most environmentally benign hydroelectric dam sites are on upper tributaries, while the most problematic ones are on the large main stems of rivers.Publication Environmental Flows in Water Resources Policies, Plans, and Projects : Findings and Recommendations(World Bank, 2009)The overall goal of the analysis presented in this report is to advance the understanding and integration in operational terms of environmental water allocation into integrated water resources management. The specific objectives of this report are the following: 1) document the changing understanding of environmental flows, by both water resources practitioners and by environmental experts within the Bank and in borrowing countries; 2) draw lessons from experience in implementing environmental flows by the Bank, other international development organizations with experience in this area, and a small number of developed and developing countries; 3) develop an analytical framework to support more effective integration of environmental flow considerations for informing and guiding: (a) the planning, design, and operations decision making of water resources infrastructure projects; (b) the legal, policy, institutional, and capacity development related to environmental flows; and (c) restoration programs; and 4) provide recommendations for improvements in technical guidance to better incorporate environmental flow considerations into the preparation and implementation of lending operations.Publication Cumulative Impacts and Joint Operation of Small-Scale Hydropower Cascades(World Bank, Washington, DC, 2014-02-01)Increasing energy demands and concerns about global warming call for an increase in energy generation from renewable sources. Small hydropower plants represent a significant contribution to meet this demand. But the optimal use of this resource in a sustainable manner still remains a challenge. A cascade of small dams may have detrimental impacts on the environment and water use without implementation of proper mitigation measures and planning. To obtain more insight in the consequences of hydropower cascades and possibilities to improve the cascade planning process in order to reduce such impacts, the Vietnamese Ministry of Industry and Trade and the World Bank jointly initiated the study on cumulative impacts and joint operation of small-scale hydropower cascades Supported by the Renewable Energy Development Program (REDP) in Vietnam. Chapter two provides a brief background on the small-scale hydropower development in Vietnam including its current planning procedures, while Chapter three provides a description of the six studied river basins. Chapter four describes the approach, methods and definitions of the study. During the first phase of the study all six rivers were screened for potential significant cumulative impacts. The results of this screening were presented in a separate report, of which the summary is given in chapter five. This screening showed that for four of the rivers significant cumulative impacts can be expected, which merited further detailed analysis. These four rivers are Ngoi Xan, Nam Tha, Nam Chien and Sap. For each of the four detailed study cases a description of the river basin and hydropower cascade has been made, the hydrological and environmental impacts were assessed and opportunities for joint operations quantified. This report presents summaries of the cumulative impact analyses (chapter six) and draws general conclusions with respect to present and future environmental conditions (chapter seven). It also summarizes the results of the optimization modeling for each cascade (chapter eight) and provides recommendations for future planning and cascade operation (chapter nine).

Publication Pakistan at 100(World Bank, Washington, DC, 2019-03-17)Pakistan has several difficult decisions to make. Despite a challenging start and a complex political history, Pakistan's economy grew fast in its earlier years, improving the lives of its citizens. Pakistan was considered an example of successful development in its first 30 years. This has since changed, and Pakistan is struggling to keep pace with the growth and transformation of its peers. Improvements in development outcomes have become slow and uneven. Pakistan@100 seeks to identify the main changes that will be necessary if Pakistan is to become a strong upper middle-income country by the time it turns 100 years old in 2047. The decisions over the next decade will determine Pakistan's future. Will Pakistan rise to the challenges ahead and transform its economy? Or will Pakistan continue with the mixed record of reform implementation, failing to address the key constraints to growth, while another generation of Pakistanis sees limited welfare improvements? This overview report together with the seven policy notes that were prepared in parallel provides a vision of the type of economy that Pakistan could have by 2047. The report illustrates the type of changes that are possible, and it discusses a limited number of priority reforms that will be necessary to address the most pressing constraints to accelerating and sustaining growth.Publication Taxes, Spending, and Equity: International Patterns and Lessons for Developing Countries(Washington, DC: World Bank, 2025-11-17)Taxes and public spending underpin the basic administration of government and finance the human capital and infrastructure investments needed for economic growth. They can also have a significant and immediate impact on poverty and inequality. The question of how public finance can support longer-term growth objectives while promoting equity has become even more important in recent years, given the high fiscal deficits and debt levels most countries emerged with in the aftermath of the COVID-19 pandemic. These included the increasing cost of debt and the need to restart environmentally sustainable growth while helping households address the learning losses and other social scars caused by the pandemic. This paper examines the global evidence on which households pay which taxes and who benefits from what spending, and critically, the net effect on different households across the income distribution. The aim is to identify the patterns and lessons that emerge for designing progressive fiscal policies. A global dataset of 96 countries is assembled, spanning all regions of the world and all national income levels, grounded in the Commitment to Equity (CEQ) approach to fiscal incidence.Publication Georgia Green Growth Strategy(Washington, DC: World Bank, 2025-07-29)The Georgian Green Growth Strategy (G3S), based on a model of sustainable development, should be inclusive and allow Georgia to efficiently and sustainably manage its natural resources, minimize pollution and environmental impact, and increase resilience to climate change. Key objectives should include sustainable natural resource management, climate adaptation and mitigation, circularity in production and consumption, green finance, and education. Progress in these areas is likely to create synergy across social, economic, and environmental development objectives.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 Uganda Economic Update, Edition 24(Washington, DC: World Bank, 2025-03-04)The Ugandan economy continues to demonstrate resilience. Inflation in Uganda has significantly decreased, falling below the central bank’s target. On the external side, the current account deficit remained high despite some moderation due to improved merchandise trade performance. Fiscal consolidation efforts continue but need more focus on domestic revenue mobilization (DRM) to mitigate negative impacts on priority expenditures like human capital investment. The medium-term outlook for Uganda remains broadly positive, with significant downside risks. Human capital - the knowledge, skills, and physical health that enable people to be productive - will play a pivotal role in improving Uganda’s long term potential growth, especially for creating more jobs in non-oil sectors. The special topic of Uganda Economic Update (UEU) 24 focuses on the critical importance of early childhood development (ECD) for Uganda’s present and future prosperity. Early childhood is the most critical period for human capital formation, because this is when people acquire fundamental cognitive, social, and emotional skills that are essential for future productivity. Given the rapid pace of brain development in early life, investments in ECD are more effective and cost-efficient than attempting to make up for missed opportunities later.
