The Hidden Wealth of Nations: The Economics of Groundwater in Times of Climate Change

(Washington, DC: World Bank, 2023-06-23) Rodella, Aude-Sophie ; Zaveri, Esha ; Bertone, François ; editors

Groundwater is our most important freshwater resource, but the lack of systematic analysis of its economic importance has evaded attention from policymakers and the general public–threatening the resource. "The Hidden Wealth of Nations: The Economics of Groundwater in Times of Climate Change" report offers new data and evidence that advances understanding of the value of groundwater, the costs of mismanagement, and the opportunities to leverage its potential.
From Source to Sea: South Asia Water Initiative Completion Report 2013 - 2021

(Washington, DC, 2022) World Bank

This Completion Report summarizes cumulative results and outcomes for the South Asia Water Initiative (SAWI) Phase 2 (from 2013-2021). SAWI’s objective was to increase regional cooperation in the management of the major Himalayan river systems in South Asia to deliver sustainable, fair, and inclusive development and climate resilience. Four interlinked pathways supported the outcomes: (i) building confidence and trust among the countries – mainly by convening regional technical dialogues; (ii) generating new technical knowledge, including in partnership with others, for national programs to use and to help shift stakeholder perceptions; (iii) building capacity of key institutions and stakeholders by exposing them to regional collaboration efforts elsewhere and training them in the use of new tools and technologies to strengthen water resource management; and (iv) scoping and leveraging investments, most notably World Bank investments so that these new approaches could be embedded and taken to scale.
Vietnam: Toward a Safe, Clean, and Resilient Water System

(World Bank, Washington, DC, 2019-05-01) World Bank Group

Prudent economic policies, combined with the enabling conditions created by a high endowment of water, have transformed Vietnam from a low income to a middle-income country within two decades. Though growth has produced vast benefits, it has also placed unrelenting pressures on water resources, which in turn lead to economic stresses. This report assesses how secure Vietnam’s water resources are and its economic implications and focuses on reducing the threats of “too little, too much, and too dirty.” Specifically, the report focuses on increasing water productivity in irrigated agriculture, water security and services for settlements, and on how Vietnam manages water quality and pollution issues, as well as climate change adaptation, disaster risks, and risks from infrastructure gaps and vulnerabilities. Recognizing that water governance is fundamental in addressing Vietnam’s water challenges, this report analyzes the current governance of the water sector to inform the development of strategies, provide an integrated view of challenges, and identify the most fundamental shifts needed to achieve national water security. Going forward, greater emphasis will have to be given to policy enforcement and to the incentives needed to assure greater compliance. The solutions suggested by this analysis are clustered around seven recommendations. This report was developed in close cooperation with the Government of Vietnam.
Rapid Review of Water Knowledge for Pacific Small Islands Developing States

(World Bank, Washington, DC, 2018-06) World Bank Group

The rapid review confirms that Pacific Small Island Developing States (SIDS) are socially, culturally, and environmentally diverse, with some features in common, and which collectively make them unique to other regions of the world: Small island countries have uniquely fragile water resources due to their small size, lack of natural storage, competing land use, and vulnerability to natural and anthropogenic hazards, including drought, cyclones, and urban pollution (with between 0.5 percent to 6.6 percent of gross domestic product (GDP) being lost annually to disasters). Rurally dominated populations are widely dispersed geographically as many small communities, while most capital cities include significant informal settlement populations and are subject to rapid urbanization (a more than 3 percent yearly increase in urban population growth in most Melanesian countries is projected between 2015 and 2020) (Mycoo and Donovan 2017).
Wastewater: From Waste to Resource - The Case of Santa Cruz de la Sierra, Bolivia

(World Bank, Washington, DC, 2018-03) World Bank

A set of case studies was prepared as part of the World Bank’s Water Global Practice initiative 'Wastewater. Shifting paradigms: from waste to resource' to document existing experiences in the water sector on the topic. The case studies highlight innovative financing and contractual arrangements, innovative regulations and legislation and innovative project designs that promote integrated planning, resource recovery and that enhance the financial and environmental sustainability of wastewater treatment plants. This case study documents Santa Cruz de la Sierra, Bolivia.
Watershed: A New Era of Water Governance in China — Synthesis Report

(World Bank, Washington, DC, 2018) World Bank Group

This report represents a synthesis of joint research conducted by the Development Research Center of the State Council of the People's Republic of China (DRC) and the World Bank. Building on the track record of research collaboration between the World Bank and the DRC on issues such as urbanization, the objective of the study is to provide Chinese policy makers with detailed institutional and policy options to support water security in the country. This study fills a critical gap highlighted in the World Bank 2013 China Country Water Resources Assistance Strategy by proposing legal, technical, and institutional changes to the current framework for water resource management. A new water governance approach is recommended that aims to balance economic growth with increasing water demand under conditions of water scarcity. By closely examining key water management issues in the context of China's rapid development, the study also aims to provide lessons relevant to other low- and middle-income countries facing similar water-related challenges. The report identifies five priority areas for reform: 1) Enhance the legislative foundation for water governance; 2) Strengthen national and basin-level water governance; 3) Improve and optimize economic policy instruments; 4) Strengthen adaptive capacity to climate and environmental change; and 5) Improve data collection and information-sharing.
Greenhouse Gases from Reservoirs Caused by Biogeochemical Processes

(World Bank, Washington, DC, 2017-12) World Bank

Reduction of greenhouse gas (GHG) emissions is fundamental to the mitigation of climate change. It has become increasingly important to estimate and report on GHG emissions to enable the implementation of mitigation measures to limit or reduce total emissions. In most cases, such estimation is fairly simple, using known emission factors per surface area or per produced energy unit. However, GHG emissions from reservoirs created for the purpose of electricity generation, water security, or flood protection are very difficult to estimate, and no single emission factor or formula can be applied. The purpose of this note is therefore to provide guidance to World Bank Group (WBG) staff on how to assess GHGs from reservoirs in preparation of dam infrastructure projects. The note discusses: (i) the major biogeochemical processes causing GHG emissions from reservoirs; (ii) the state of current knowledge, and (iii) recommendations for assessing GHG emissions caused by biogeochemical processes for planned reservoirs.
Climate Resilience in Africa: The Role of Cooperation around Transboundary Waters

(World Bank, Washington, DC, 2017-06-27) World Bank Group

Addressing water-challenges is central to building climate resilience. In Africa, all major waters are transboundary making cooperation on international waters critically important to building climate resilience. Regional-national coordination is needed if the full range of options for building resilience is to be considered. Furthermore, experience shows that cooperative action can outweigh transaction costs, bring about efficiency gains, and change behavior of cooperating countries to be more future-oriented, leading to an expansion of potential resilience benefits in the longer term. This report draws on a substantial body of empirical evidence from five major basins in Africa - including the Nile, Zambezi, Limpopo, Lake Chad, Niger basins - to support the critical role of transboundary cooperation on water resources management to building systemic resilience to climate change in Africa.
Physical Impacts of Climate Change on Water Resources

(World Bank, Washington, DC, 2017-02-08) Miralles-Wilhelm, Fernando ; Clarke, Leon ; Hejazi, Mohamad ; Kim, Sonny ; Gustafson, Kelly ; Munoz-Castillo, Raul ; Graham, Neal

Despite the well-recognized role of water in transmitting climate impacts to some of the growth drivers of the economy, the water sector has been largely ignored in climate change deliberations. The impacts are projected to vary regionally, and are likely to include changes in average hydroclimate patterns (precipitation, surface runoff, and stream flow), as well as increases in the probability of extreme events. Climate shocks are likely to impose higher costs than gradual changes in climate averages. Prudent management of water resources will be pivotal in addressing the climate challenge—both for adapting to the effects of climate change as well as for meeting global greenhouse gas mitigation goals. The precise consequences of climate change on the hydrological cycle are uncertain, which makes adaptation especially challenging. Uncertainty regarding impacts is partly a consequence of the limitations of climate models. Despite improvements in climate science, the Global Circulation Models developed to project climate futures generate a wide range of projections that often disagree on both the direction and magnitude of precipitation changes. Furthermore, these models have not been designed to predict changes in the hydrological cycle and lack the precision required for planning and managing water resources. In addition to this, changes in the hydrological cycle imply that future water systems may not resemble the past (non-stationarity), so historic trends as used in engineering designs, no longer serve as a reliable guide for assessing and managing future risks. This study presents an investigation of the impacts of climate change on water resources throughout the world, and specific effects on water dependent sectors of the economy such as urban, energy, and agriculture. The results can be used to illustrate the centrality of water in achieving global climate change goals.
Simulating the Macroeconomic Impact of Future Water Scarcity

(World Bank, Washington, DC, 2017-02-08) Roson, Roberto

In this paper we consider some of the economic implications of climate change scenarios as described in the Shared Socioeconomic Pathways (SSPs). By comparing potential water demand with estimates of (sustainable) water availability in different regions, we identify regions that are likely to be constrained in their future economic growth potential by the scarcity of water resources. We assess the macroeconomic impact of water scarcity under alternative allocation rules finding that, by assigning more water to sectors in which it has a higher value, shifting production to less water intensive sectors, and importing more water intensive goods, constrained regions can effectively neutralize these water related climate risks and adapt to a changing water environment. However, this adaptation effort is likely to imply some radical changes in water management policies.
