This report sets out the challenge for freshwater in a changing climate and provides policy guidance on how to navigate this new “waterscape”. It highlights the range of expected changes in the water cycle and the challenge of making practical, on-site adaptation decisions for water. It offers policymakers a risk-based approach to better “know”, “target” and “manage” water risks and proposes policy guidelines to prioritise action and improve the efficiency, timeliness and equity of adaptation responses.
The report also highlights general trends and good practices drawn from the OECD Survey of Policies on Water and Climate Change Adaptation, covering all 34 member countries and the European Commission. Individual country profiles are available, which provide a snapshot of the challenges posed by climate change for freshwater and the emerging policy responses (on-line only).
Finally, the report highlights the benefits of well-designed economic instruments (e.g. insurance schemes, water trading, water pricing), ecosystem-based approaches and ‘real options’ approaches to financing. These approaches can improve the flexibility of water policy and investment, reducing the cost of adjusting to changing conditions.
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.
Climate change combined with rapid population increases, economic growth and land subsidence could lead to a more than 9-fold increase in the global risk of floods in large port cities between now and 2050.
This report examines six mechanisms that can be used to scale-up financing for biodiversity conservation and sustainable use and to help meet the 2011-20 Aichi Biodiversity Targets. The mechanisms are environmental fiscal reform, payments for ecosystem services, biodiversity offsets, green markets, biodiversity in climate change funding, and biodiversity in international development finance. Drawing on literature and more than 40 case studies worldwide, this book addresses the following questions: What are these mechanisms and how do they work? How much finance have they mobilised and what potential is there to scale this up? And what are the key design and implementation issues that need to be addressed so that governments can ensure these mechanisms are environmentally effective, economically efficient and distributionally equitable?

Presentation for the CGDD-OECD Seminar on the assessment of ecosystem services and its use for public policies.
A one-day seminar organised jointly by the OECD and the General Commission for Sustainable Development (Commissariat général au Développement durable -CGDD). The objective of the seminar was to examine the link between assessment of ecosystem services and the design and enforcement of public policies at national and local levels.

The eleventh meeting of the Convention on Biological Diversity was held in Hyderabad, India (COP11, from 8 to 19 October 2012).
This report provides a framework for policy discussions around financing water resources management that are taking place at local, basin, national, or transboundary levels.
Environment Ministers reviewed the implementation of the Environmental Strategy, discussed priorities based on the Environmental Outlook to 2050 which is a strong case for green growth policies and adopted a policy statement as input to Rio+20 UN Conference.
