Adapting to climate change. Jonathan Suk 30 June 2010. Drivers of emerging infectious diseases. Main categories of drivers associated with emergence and re-emergence of human pathogens. Rank*Driver. 1Changes in land use or agricultural practices. - PowerPoint PPT Presentation


Adapting to climate changeJonathan Suk30 June 2010Add new slides with CTRL-M.Helpful hints:1. Write "Total outpatient antibiotic use in Europe", not "Total Outpatient Antibiotic Use in Europe".2a. Write "Member States", not "MS", i.e. avoid avoidable abbreviations.2b. Write "and", not "&".2c. Write "three", not "3".3. Write: "HIV infections", not "HIV INFECTIONS".4. No pink, purple, and red, especially not in headlines.5. Use soft returns (CTRL-RETURN) instead of hard returns (RETURN) whenever possible.6. Don't centre text! All text should be aligned left.7. Don't enlarge pictures beyond their actual size/resolution.8. Don't use italics, except for e.g. 'Clostridium difficile'.9. Crop pictures.10. Make sure you understand how bulleted lists work.

1. Vector Surveillance: VBORNETObjectives

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

3. Adaptation handbookBackgroundClimate change as a threat multiplier addressing climate-sensitive diseases should also benefit public health today


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.

10Pragmatic approachIdentify baseline description (epidemiologic, socio-economic, current disease burden), and note it is changing alongside climateIdentify climate-sensitive diseases most relevant for a given region, and then weighing options for actionIdentify climatic drivers (rainfall, drought, temperature) most relevant to these diseasesDevelop adaptation strategies with future projections in mind, and engage other sectors where possibleStrategy needs to be evidence-based, but does not necessarily need to involve sophisticated modelling
