Water Resources Group (WRG) catalyzes collaboration between the private sector and government to tackle water security challenges and climate change impacts. Its engagements center on four steps: framing choices to support effective decision-making, facilitating country platforms, supporting implementation, and scaling solutions.

Tariffs are essential but not the only pathway to cost recovery, addressing affordability, and managing water conservation. To maximize their potential, they must be well designed, complemented by appropriate instruments, adequately regulated, and understood by customers. This report builds upon that one, and provides policy makers with the information needed to design better tariffs to further the economic efficiency, affordability, and environmental sustainability of water supply services. Through a layered and comprehensive analysis of the most prevalent tariff structures, it provides policy makers with specific guidance on pricing water supply services in response to the sector’s often-competing goals. This document comprises a synthesis of fifteen unique research papers that, combined, articulate a step-by-step thought process for designing effective tariffs with a view to achieving sustainable development goal (SDG) 6.

This case study is part of a series prepared by the World Bank’s Water Global Practice to highlight existing experiences in the water sector. The purpose of the series is to showcase one or more of the elements that can contribute toward a Water in Circular Economy and Resilience (WICER) system. This case focuses on the experience of Portugal.

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.

Lake Victoria, a vital resource for East African countries, faces threats from unsustainable land management, human waste, and industrial effluent, impacting its water quality, biodiversity, and navigability. Recognized as a regional economic zone by the East African Community, the Lake Victoria Basin (LVB) requires aC coordinated regional approach to address these challenges. The Lakewide Inclusive Sanitation (LWIS) Strategy offers a multilateral solution to the basin's sanitation issues, exacerbated by rapid urbanization and inadequate wastewater treatment. With 33 million people in the LVB lacking improved sanitation, the LWIS Strategy aims to improve water quality and human capital through comprehensive sanitation improvements, technical innovation, institutional reforms, and financial mobilization. This approach also engages the private sector in innovation, service delivery, and job creation, emphasizing the need for a strong, coordinated regional effort to enhance lake functions, provide safe sanitation, and strengthen community resilience against climate change and other crises.

Rethinking urban water through the circular economy and resilience lenses offers an opportunity to transform the urban water sector and deliver water supply and sanitation services in a more sustainable, inclusive, efficient, and resilient way. Circular Economy principles have emerged as a response to the current unsustainable linear model of "take, make, consume, and waste." In a circular economy, the full value of water – as a service, an input to processes, a source of energy and a carrier of nutrients and other materials – is recognized and captured. This report presents the Water in Circular Economy and Resilience (WICER) Framework together with global case studies that show the benefits of becoming circular and resilient. It describes the key actions needed to achieve three main outcomes: 1) deliver resilient and inclusive services, 2) design out waste and pollution, and 3) preserve and regenerate natural systems. The report sets out to demystify circular economy by showing that both high-income and low-income countries can benefit from it.

Water management is foundational for development and climate adaptation. Investments in water not only improve health and wealth of nations but can also buffer the impacts of climate change. Sub-Saharan Africa (SSA) is the most vulnerable region to climate change impacts. This policy note examines national development vision documents and Nationally Determined Contributions (NDC) documents across SSA to: (1) review the extent to which water and water related climate priorities feature in them; (2) propose substantive improvements to the presentation of water and water related climate priorities; and, (3) identify practical ways water sector actors can engage in shaping national planning documents going forward. The analysis shows that water and water-related climate actions are not consistently included in either national vision documents or NDCs across SSA. Most country’s vision documents (91 percent) aimed to improve access to water supply and sanitation (WSS) but only half of the visions aimed to expand irrigation and hydropower. Water resources management (WRM), though referenced in two thirds of the visions was poorly defined and only very few cases described institutional mechanisms for managing water. Water adaptation measures featured in all SSA countries’ NDCs but were often generic in nature without clear indicators or targets. For example, early warning systems (EWS) were included in over two thirds of NDCs but only a few countries were specific about when or how EWS would be set up. WRM measures in NDCs were even less specific than those included in national visions. Water related mitigation measures in NDCs were less frequently included than adaptation measures. For example, only a quarter of NDCs mentioned improving energy efficiency in WSS and only one country set a specific target to reduce energy intensity. As vision documents and NDCs get revised there is a window of opportunity to ensure that water and its subsectors (WSS, irrigation, hydropower and WRM) are presented with clear indicators and targets. Half of the countries in SSA will revise their visons in the 2020s and NDCs are revised every 5 years.
