Ozone trends and impacts on health and crop yields [chapter 4]

This assessment report summarises current scientific knowledge on transboundary air pollution issues within the UNECE region and describes the effectiveness of air pollution measures in addressing large-scale effects on forests and lakes as well as in protecting human health and preventing other air pollution effects, such as loss in biodiversity and damage to crops, the built environment and cultural heritage. The aim of this assessment is to serve as a basis for considering new directions for policy development and for identifying policy-relevant research questions. The international co-operative approach, which includes interaction between science and policy, as developed under the Convention, provides a good basis for exploring synergies between air pollution and climate change, agriculture and biodiversity, and energy and public health policies on the urban, national,continental and hemispheric scale.
