As part of the OECD's Pesticide Programme, a Workshop on Avian Toxicity Testing was held in Pensacola, Florida, on 4-7 December 1994. It was jointly organised by the Society of Environmental Toxicology and Chemistry (SETAC) and the OECD. This Workshop report considers the fundamental reasons information about the toxicity of chemicals to birds is needed, and thereby identify the critical features which are essential for the tests used to generate this information;  evaluates the positive and negative features of existing test methods, and of proposed alternatives, against the required critical features;   develops proposals for the revision and development of OECD Test Guidelines for avian toxicity and avoidance tests, as appropriate; and develops a framework to govern the way these tests are requested and used in practice in risk assessment.

OECD member countries have been making efforts to expand the use of alternative methods in assessing chemicals. The OECD has been developing guidance documents and tools for the use of alternative methods such as (Q)SAR, chemical categories and Adverse Outcome Pathways (AOPs) as a part of Integrated Approaches for Testing and Assessment (IATA). There is a need for the investigation of the practical applicability of these methods/tools for different aspects of regulatory decision-making, and to build upon case studies and assessment experience across jurisdictions. The objective of the IATA Case Studies Project is to increase experience with the use of IATA by developing case studies, which constitute examples of predictions that are fit for regulatory use. The aim is to create common understanding of using novel methodologies and the generation of considerations/guidance stemming from these case studies. This document reports the learnings and lessons obtained from the review experience of the four case studies submitted to the 2015 review cycle of the IATA Case Studies project. The topics discussed in this document include the strongest aspects and uncertainties of each case study, and the document identifies areas for developing further guidance on IATA.

This report describes the online Pesticide Risk Indicators (PRIs) database and how to use it. This online tool was developed based on information collected from OECD member countries on existing PRIs, and it includes evaluations and summaries of the information provided.

This document sets out recommended procedures to use when requesting and carrying out inspections and study audits in another country under the Principles of Good Lab Practice and Compliance Monitoring.

Over the last decades, and in line with the adoption of the Sustainable Development Goals (SDGs) in 2015, cities and regions have played an important part in helping to implement global agendas at local level through their Decentralised Development Cooperation (DDC) activities. This report analyses the evolution of financial flows, emerging trends and innovative paradigms related to the development co-operation of local and regional governments, including but not limited to official development assistance extended by sub-national governments. It promotes a territorial approach to development co-operation and provides policy recommendations to maximise the effectiveness, benefits and outcomes of DDC at all levels, while acknowledging the diversity of approaches, definitions and concepts across OECD DAC countries active in DDC.

There is an urgent need to ensure that coastal areas are adapting to the impacts of climate change. Risks in these areas are projected to increase because of rising sea levels and development pressures. This report reviews how OECD countries can use their national adaptation planning processes to respond to this challenge. Specifically, the report examines how countries approach shared costs and responsibilities for coastal risk management and how this encourages or hinders risk-reduction behaviour by households, businesses and different levels of government. The report outlines policy tools that national governments can use to encourage an efficient, effective and equitable response to ongoing coastal change. It is informed by new analysis on the future costs of sea-level rise, and the main findings from four case studies (Canada, Germany, New Zealand and the United Kingdom).

This new OECD report on the ocean economy emphasises the growing importance of science and technologies in improving the sustainable economic development of our seas and ocean. Marine ecosystems sit at the heart of many of the world’s global challenges: food, medicines, new sources of clean energy, climate regulation, job creation and inclusive growth. But we need to safeguard and improve the health of marine ecosystems to support our ever-growing use of marine resources. Innovation in science and technology will play a key role in reconciling these two objectives. This report identifies three priority areas for action based on a number of in-depth case studies: 1) approaches that produce win-win outcomes for ocean business and the ocean environment across a range of marine and maritime applications; 2) the creation of ocean-economy innovation networks; and 3) new pioneering initiatives to improve measurement of the ocean economy.

This report provides a new perspective to the nature of urban sprawl and its causes and environmental, social and economic consequences. This perspective, which is based on the multi-dimensionality of urban sprawl, sets the foundations for the construction of new indicators to measure the various facets of urban sprawl. The report uses new datasets to compute these indicators for more than 1100 urban areas in 29 OECD countries over the period 1990-2014. It then relies on cross-city, country-level and cross-country analyses of these indicators to provide insights into the current situation and evolution of urban sprawl in OECD cities. In addition, the report offers a critical assessment of the causes and consequences of urban sprawl and discusses policy options to steer urban development to more environmentally sustainable forms.

This guidance document was originally published in 2012 and updated in 2018 to reflect new and updated OECD test guidelines, as well as reflect on scientific advances in the use of test methods and assessment of the endocrine activity of chemicals. The document is intended to provide guidance for evaluating chemical using standardised test guidelines. Specific objectives include providing a description of the OECD conceptual framework for evaluating chemicals for endocrine disruption, background on the standardised test methods used, and guidance for interpreting the outcome of individual tests. The general approach taken by the document is primarily to provide guidance on how test results might be interpreted based on the outcome of standardised assays. Key questions addressed in the document concern likely mechanisms of endocrine action and any resulting apical effects that can be attributed to such action. The document is not proscriptive but provides suggestions for possible next steps in testing (if any) which might be appropriate for a regulatory authority to take, given the various data scenarios. The guidance document is focused primarily on endocrine modalities included in the conceptual framework; estrogen, androgen, and thyroid mediated endocrine disruption and chemicals that interfer with steroidogenesis.

This document provides guidance for the conduct of laboratory inspections and study audit under the Principles of Good Laboratory Practice.
