Seeing the Invisible: A Strategic Report on Groundwater Quality

(Washington, DC: World Bank, 2022-03-23) Ravenscroft, Peter ; Lytton, Lucy

This report describes why, and how, groundwater quality is vital to human health, agriculture, industry and the environment. In turn, this explains why it is so important to World Bank staff and clients, as well as diverse managers and administrators in countries and economies at all stages of development.
Practical Manual on Groundwater Quality Monitoring

(Washington, DC: World Bank, 2022-03-20) Ravenscroft, Peter ; Lytton, Lucy

This is a companion volume to “Seeing the Invisible: A Strategic Report on Groundwater Quality,” which explains why groundwater quality is so important to managers of development programs in the World Bank and elsewhere. Its purpose is to provide managers and their teams with practical guidance on how to set up and manage a groundwater quality monitoring program. It provides a logical, step-by-step approach that can be tailored to, and grow with, the capacity to implement such a program. The guiding principle is that monitoring is the fundamental activity that shapes our identification of issues, the framing of problems, the design of solutions, and the measurement of the effectiveness of those solutions. Monitoring is often seen as simple and undervalued, but monitoring of groundwater quality, and its interpretation, is technically demanding. On the other hand, it is also extremely rewarding.
Advancing Knowledge of the Water-Energy Nexus in the GCC Countries

(World Bank, Washington, DC, 2022) Jägerskog, Anders ; Barghouti, Shawki

Climate change and increasing population pressure make it increasingly urgent to find ways to improve the management of the water-energy nexus. The desalination, pumping, distribution, and treatment of water use significant energy resources. The extraction and production of energy consume substantial amounts of water resources. In addition, negative effects on the environment are often the consequences of the management of the water and energy sectors. The report highlights the prospects for addressing these and other challenges at the water-energy nexus. It does this by drawing, in part, on some of the most important breakthroughs in the nexus that have come from the region.
Argentina Valuing Water: Brief for Policy Makers

(World Bank, Washington, DC, 2021-06-23) World Bank

This brief for policy makers is a summary of the main conclusions derived from the “Argentina: Valuing Water” report, a detailed and technical water security diagnostic, and is designed for decision makers beyond the water sector. Its main purpose is to make visible the importance of water, and the cost of existing water security gaps on Argentina’s economy, society and environment. The report further highlights the causes behind those water security gaps and identifies opportunities to close them and make the country more resilient to climate change or to other shocks such as the COVID-19, through a more sustainable, inclusive and efficient water management. The document assesses the water security situation today, evaluating the impacts of these water security gaps in the country’s GDP, and then proposes two future scenarios up to 2030: the first one is a “business as usual” scenario, where there are no changes in the way water is managed today, and where water security gaps perpetuate or amplify due to climate change and growing demands. The second “active scenario” is that one where a series of investments are proposed to close the existing gaps, and where, most importantly, a number of water governance reforms are recommended to complement such investments and to make them more sustainable. These reforms are also necessary to use public funds more efficiently, a priority measure in times of crisis.
Moldova: Water Security Diagnostic and Future Outlook

(World Bank, Washington, DC, 2020-11-18) Smets, Susanna ; Midgley, Amelia ; Mao, Zhimin ; Vladicescu, Veaceslav ; Neumann, James E. ; Strzepek, Ken ; Pricop, Felicia

Over the past two decades Moldova has achieved major development results: poverty more than halved between 2007 and 2014, and shared prosperity for the poorest households rose sharply. Yet Moldova’s growth model is volatile, unsustainable, and is losing strength. Water underpins much of Moldova’s ability to rekindle dynamism in its economy and to provide outcomes for the health and well-being of its people and environment. Yet gaps remain in understanding the country’s water resources endowments. This diagnostic suggests that in 2018 water availability is not a binding constraint to development. Even in the presence of future changes in demand, there are limited or manageable physical constraints to water security. Going beyond a focus on the water balance, this report assesses Moldova’s water security and identifies important water-related challenges that may hinder progress in economic and human development. Moldova’s water security is threatened by poor infrastructure and suboptimal institutional performance. Through an assessment of service delivery, water resources management and risk mitigation, and an analysis of institutional arrangements and sector expenditure data, this diagnostic establishes a set of policy recommendations on how water should be sustained and leveraged to support Moldova’s development. This report provides a new, comprehensive, and balanced view of water security in Moldova, highlighting the complex water issues that Moldova must tackle to improve its water security. It seeks to elevate water security as an issue critical for national development by providing stakeholders with a stocktaking and outlook on water-related risks, and opportunities in which water can contribute to economic growth and poverty reduction.
Remote Sensing of Water Quality in Laguna del Sauce, Uruguay

(World Bank, Washington, DC, 2020-05) World Bank

Laguna del Sauce is a water supply reservoir located in the Department of Maldonado (Uruguay), approximately 15 kilometers west of Punta del Este and 100 kilometers east of Montevideo. This case study assessed ongoing initiatives to address surface water pollution issues in Uruguay, working in partnership with a team of government agencies charged with water resource management. This assessment will contribute to better understanding of options for water-quality remote sensing capabilities and needs. It will also assist the government of Uruguay in identifying appropriate remote sensing tools and devising an application strategy to provide information needed to support decision making regarding the targeting and monitoring of nutrient pollution prevention and mitigation measures.
Resilient Water Infrastructure Design Brief

(World Bank, Washington, DC, 2020) World Bank

The purpose of the Resilient Water Infrastructure Design Brief is to guide users on how resilience can be built into the engineering design of their project. With a focus on the three natural hazards most likely to affect water and sanitation infrastructure (droughts, floods, and high winds from storms), the document provides a six-step process to help users address weather and climate related challenges that are most likely to affect an infrastructure component at some point in its operational lifetime. In order to achieve both systems level resilience and infrastructure level resilience, this design brief should be used in tandem with other World Bank publications, such as the 2018 guidance document “Building the Resilience of WSS Utilities to Climate Change and Other Threats: A Road Map,” which emphasizes systems level resilience and analysis. The design brief highlights the relationship between these two documents and the unique function that each serves in improving overall resilience in the water sector. It also includes guidance for users to incorporate resilience design principles into projects’ appraisal documents and a sample module/task description for applying the two documents to an engineering design or feasibility study terms of reference.
Determinants of Declining Water Quality

(World Bank, Washington, DC, 2019-12-19) Ayana, Essayas

This is a background paper for "Quality Unknown: The Invisible Water Crisis." (Report No. 140973)This review examines determinants of poor water quality and natural and anthropomorphic factors determining water quality. It also discusses various water quality parameter measurement tools that can be applied in situ or remotely to assess water quality easily so measurements can be used to evaluate the economic impact of poor water quality. The correlation of water quality indicators to determinants (natural or anthropogenic) is also summarized based on the abundance of literature supporting the relationship. In doing so, this paper takes a thematic approach and applied the following search phrases to the literature review: "determinants of (parameter) in surface water," "drivers of (parameter) in surface water," and "remote sensing techniques to estimate (parameter)."
Building Urban Water Resilience in Small Island Countries: The Case of South Tarawa, Kiribati

(World Bank, Washington, DC, 2019-10) World Bank

The water sector in South Tarawa, the capital city of Kiribati, is entering a time of deep transition. In a small island context risks can materialize faster than elsewhere and have disproportionate consequences. Strengthening water sector resilience is therefore critical to people’s welfare and to the economy. This report was conducted in parallel to the preparation of the South Tarawa Water Supply Project, to provide a diagnostic of the remaining vulnerabilities the capital city’s water supply sector may face after the completion of this project. Its main objective is to inform decisions by the Government of Kiribati on how to address these vulnerabilities. Section one gives introduction. Section two sets the stage with a brief presentation of the concept of water supply resilience in a context of water scarcity. Section three provides a summary of water supply conditions in South Tarawa and analyzes the impacts of various stresses and shocks on freshwater availability. Section four discusses potential measures to reduce water supply deficits during major crises. Section five offers an overview of these measures, in the form of an action plan, and presents several lessons that can be applied in water scarce cities in small islands and elsewhere.
Better Data, Better Results: Remote Sensing as a Tool for Monitoring Water Quality in Lake Toba, Indonesia

(World Bank, Washington, DC, 2019-06-01) World Bank

Lake Toba is a unique natural asset of global significance with a rich cultural heritage located in the North Sumatra Province of Indonesia. Located 904 meters above sea level and with a maximum depth of more than 500 meters, this 87-kilometer-long lake provides a wide range of economic and environmental goods and services for more than half a million people and 400 villages in the seven districts covered by the lake's 3,658 square kilometer catchment. However, sustaining the long-term economic and environmental value of Lake Toba depends on addressing the deterioration of water quality. This technical guidance note reports on the potential benefits of using remote sensing as part of an integrated strategy to improve the monitoring and management of water quality in Lake Toba.
