Extreme temperatures, including heat and cold waves, are climatological hazards. Both in the EU as in EU-Neighbourhood countries, research has shown that heatwaves cause a rise in morbidity and mortality. Since heatwaves are not restricted to country borders, a cross-border approach is required to ensure collective preparedness and response to mitigate the impacts on communities and limit the financial and health costs. The overall objective of SCORCH is to reduce the impact of heatwaves on vulnerable, urban populations through improved risk communication strategies based on existing EU plans and guidelines. In addition, we will measure risk perception and behaviour in communities in EU-neighbourhood countries through surveys and foster a cross-country culture of prevention and cooperation. To make maximum use of existing knowledge and strategies on heatwaves, the project started out by collecting existing heatwave plans of EU countries (D2.1). In this report, we go one step further and review literature that analyses heatwave plans of EU countries, Switzerland, Norway or EU candidate countries. The review is aimed at assessing the effectiveness of the heatwave plans, based on a desk study, and addresses two research questions: 1. How effective are the processes described in the national heatwave plans with regard to their implementation and risk management? 2. How effective are the national heatwave plans in changing behaviour and perceptions of the public and in particular vulnerable populations regarding heatwaves? The first research question focuses on the professionals involved in the national plan and the extent to which they succeed in effective implementation. The second research question focuses on the perspective of the populations targeted by the plan, i.e. the general public and vulnerable populations, and the extent to which the plan succeeds in sensitising and mobilising populations and involved stakeholders. The report outlines the methodology used for the systematic literature review, and describes the results of this effort.
