This publication examines the critical issues surrounding water security (water shortage, water excess, inadequate water quality, the resilience of freshwater systems), providing a rationale for a risk-based approach and the management of trade-offs between water and other policies.

This publication examines the critical issues surrounding water security (water shortage, water excess, inadequate water quality, the resilience of freshwater systems), providing a rationale for a risk-based approach and the management of trade-offs between water and other (sectoral and environmental) policies. The report sets out a three-step process to "know", "target" and "manage" water risks: (1) appraising the risks, (2) judging the tolerability and acceptability of risks and weighing risk-risk trade-offs, and (3) calibrating appropriate responses. The publication provides policy analysis and guidance on the use of market-based instruments and the complex links between water security and other policy objectives, such as food security, energy security, climate mitigation and biodiversity protection.

This report focuses on the urban water management challenges facing cities across OECD countries, and explores both national and local policy responses with respect to water-risk exposure, the state of urban infrastructures and dynamics, and institutional and governance architectures.

The COVID-19 pandemic has acted as a magnifying glass on pressing water and sanitation challenges in African cities, stressing and widening inequalities, especially for the 56% of the urban population living in informal settlements, lacking basic handwashing facilities, and relying on public water points and shared toilets.

This publication sets out the challenge for freshwater in a changing climate and provides policy guidance on how to navigate this new "waterscape".

Capturing information from 27 OECD countries and key partner economies, the report presents key findings from the OECD Survey of Water Resources Allocation and case studies of successful allocation reform.

Agriculture is expected to face increasing water risks that will impact production, markets, trade and food security - risks that can be mitigated with targeted policy actions on water hotspots.

The OECD and the Directorate-General for Environment, the European Commission department responsible for EU policy on the environment, joined forces to examine current and future water-related financing challenges faced by EU member states. These include investments needed to comply with EU regulation for water supply, wastewater collection and treatment, and flood protection.

Building on a survey of 48 cities in OECD countries and emerging economies, the report analyses key factors affecting urban water governance, discusses trends in allocating roles and responsibilities across levels of government, and assesses multi-level governance gaps in urban water management.

While COVID-19 has hit Peru particularly hard, with more than half a million cases, the pandemic further emphasised the importance of water and sanitation for health, the environment and the economy. The country is not yet on track to meet the targets of SDG 6 “Clean water and sanitation” by 2030, with 3.4 million Peruvians (10.2% of the population) lacking improved access to water services and 8 million Peruvians (25.5%) without improved access to sewerage services, and a large urban-rural divide.
