After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, associated transactions costs, and limited political acceptability of regulatory measures. This report outlines the water quality challenges facing OECD countries today, presents a range of policy instruments and innovative case studies of diffuse pollution control, and concludes with an integrated policy framework to tackle diffuse water pollution. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and beneficiary pays principles, equity, and policy coherence.
The Toolkit for Water Policies and Governance compiles policies, governance arrangements and related tools that facilitate the design and implementation of water management practices in line with the OECD Council Recommendation on Water.
This report assesses the key bottlenecks within the water-energy-land-food nexus in Korea, and proposes policy recommendations and governance arrangements to future-proof environmental integrity and enhance sustainable growth. The increasing pressure caused by urbanisation, industrialisation ...
This report examines the current system of water abstraction and pollution charges in operation in Brazil. It assesses the Current system’s implementation challenges and provides possible solutions.
OECD Environmental Performance Reviews provide independent assessments of countries’ progress towards their environmental policy objectives. Reviews promote peer learning, enhance government accountability, and provide targeted recommendations aimed at improving environmental performance ...
This report presents the policy recommendations resulting from the National Dialogue on Water in Indonesia, which took place between June 2022 and March 2023. Getting water resources management right, underpinned with appropriate financing mechanisms, is a prerequisite for realising Indonesia’s ambitious national economic growth agenda to become one of the top five global economies by 2045. The Dialogue, therefore, centred around two priority areas: 1) financing water infrastructure and 2) non-structural measures for flood disaster risk reduction. The report explores several instruments to enhance the financing of water services in Indonesia, such as the advantages and disadvantages of uniform water tariffs, independent economic regulation, pollution charges and demand management instruments. The report recommends the utilisation of land value capture as an additional source of financing. It also explores how water information systems for disaster response, flood forecasting and early warning can reduce flood disaster risk. The National Dialogue on Water in Indonesia is part of a regional initiative with the Ministry of Environment of the Republic of Korea, the Asia Water Council and the OECD.
This report presents a summary of the key challenges and opportunities related to financing that contributes to water security and sustainable growth distilling insights from the Roundtable on Financing Water and related analyses. It covers a broad range of water-related investments, including water and sanitation services, water resources management, agricultural water and managing water-related risks (“too much”, “too little” and “too polluted”).
The review provides 36 recommendations to help Chile improve its environmental performance, with a special focus on water management and policies. It provides an independent, evidence-based evaluation of the country’s environmental performance since the previous review in 2016.
Microplastics are ubiquitous in the natural environment. This report synthesises the current state of knowledge on the sources, fate and risks of microplastics pollution. It then focuses on two sources of microplastics pollution, textile products and vehicle tyres, due to their substantial contribution to global microplastics emissions and currently largely absent policy frameworks to mitigate them.
