8. 1. Vector Surveillance: VBORNET Objectives  To establish a network of expertise in entomology across the EU  To obtain data on vectors of primary concern to health in the EU (mosquitos, ticks)  To promote EU-wide harmonization of standards and methods for vector surveillance 8

9. 2. Environmental monitoring 9 time Health outcomes Environmental consequences Climate change CO 2 Socio- economic impacts (homelessness, refugees…) Indirect exposures (vector-borne diseases, other infectious diseases) Surveillance Direct exposures (heat stroke, drowning…)

10. 3. Adaptation handbook Background  Climate change as a threat multiplier – addressing climate-sensitive diseases should also benefit public health today Objectives  To assist EU Member States to conduct national and regional vulnerability assessments as concerns climate change and communicable diseases  To develop comprehensive advice for ECDC and EU Member States on how to implement regionally targeted adaptation strategies to mitigate against future communicable disease transmission due to climate change. 10

11. Pragmatic approach  Identify baseline description (epidemiologic, socio-economic, current disease burden), and note it is changing alongside climate  Identify climate-sensitive diseases most relevant for a given region, and then weighing options for action  Identify climatic drivers (rainfall, drought, temperature) most relevant to these diseases  Develop adaptation strategies with future projections in mind, and engage other sectors where possible  Strategy needs to be evidence-based, but does not necessarily need to involve sophisticated modelling 11

12. Assessment Process 12 Aim, demarcation Quality control Organisational structure: Working group, reference group, etc Base-line description Climate, diseases, vulnerability factors Assessment: Vulnerability and impacts Base-line description Adaptation measures Assessment: Adaptive strategies and measures Follow-up/ monitoring: Impacts and measures Policy decision Iterative process
