1. Threat Assessment How do we manage risk? Christopher Young

2. World Heritage Committee Concerns Two Committee processes dealing with risk assessment and threats, at least in part: Reactive Monitoring leading, possibly, to In Danger Listing Periodic Reporting Committee has also asked specifically for high awareness of risk preparedness and impacts of climate change

3. Reactive Monitoring 169. Reactive Monitoring is the reporting by the Secretariat, other sectors of UNESCO and the Advisory Bodies to the Committee on the state of conservation of specific World Heritage properties that are under threat. To this end, the States Parties shall submit by 1 February to the Committee through the Secretariat, specific reports and impact studies each time exceptional circumstances occur or work is undertaken which may have an effect on the state of conservation of the property. Reactive Monitoring is also foreseen in reference to properties inscribed, or to be inscribed, on the List of World Heritage in Danger as set out in paragraphs 177- 191.Reactive Monitoring is foreseen in the procedures for the eventual deletion of properties from the World Heritage List as set out in paragraphs 192-198.

4. Criteria for In Danger Listing 179. In the case of cultural properties: a) ASCERTAINED DANGER - The property is faced with specific and proven imminent danger, such as: i) serious deterioration of materials; ii) serious deterioration of structure and/or ornamental features; iii) serious deterioration of architectural or townplanning coherence; iv) serious deterioration of urban or rural space, or the natural environment; v) significant loss of historical authenticity; vi) important loss of cultural significance.

5. b) POTENTIAL DANGER - The property is faced with threats which could have deleterious effects on its inherent characteristics. Such threats are, for example: i) modification of juridical status of the property diminishing the degree of its protection; ii) lack of conservation policy; iii) threatening effects of regional planning projects; iv) threatening effects of town planning; v) outbreak or threat of armed conflict; vi) gradual changes due to geological, climatic or other environmental factors.

6. 180. In the case of natural properties: a) ASCERTAINED DANGER - The property is faced with specific and proven imminent danger, such as: i) A serious decline in the population of the endangered species or the other species of outstanding universal value for which the property was legally established to protect, either by natural factors such as disease or by man-made factors such as poaching. ii) Severe deterioration of the natural beauty or scientific value of the property, as by human settlement, construction of reservoirs which flood important parts of the property, industrial and agricultural development including use of pesticides and fertilizers, major public works, mining, pollution, logging, firewood collection, etc. iii) Human encroachment on boundaries or in upstream areas which threaten the integrity of the property.

7. b) POTENTIAL DANGER - The property is faced with major threats which could have deleterious effects on its inherent characteristics. Such threats are, for example: i) a modification of the legal protective status of the area; ii) planned resettlement or development projects within the property or so situated that the impacts threaten the property; iii) outbreak or threat of armed conflict; iv) the management plan or management system is lacking or inadequate, or not fully implemented.

8. State Party responsibilities 4 Each State Party to this Convention recognizes that the duty of ensuring the identification, protection, conservation, presentation and transmission to future generations of the cultural and natural heritage referred to in Articles 1 and 2 and situated on its territory, belongs primarily to that State. It will do all it can to this end, to the utmost of its own resources and, where appropriate, with any international assistance and co-operation, in particular, financial, artistic, scientific and technical, which it may be able to obtain. 5 Each State Party to this Convention shall endeavor, in so far as possible, and as appropriate for each country: (c) to develop scientific and technical studies and research and to work out such operating methods as will make the State capable of counteracting the dangers that threaten its cultural or natural heritage;

9. Sources of help ICOMOS/ICCROM/UNESCO manual (1998) International Committee of Blue Shield (set up by ICA, ICOM, ICOMOS, IFLA) National Committees of Blue Shield: Norway: contact Axel Mykleby http://www.blueshield.no http://www.blueshield.no Blue Shield set up to support on 1954 Hague Convention but also can advise on natural disaster

10. Some Threats Earthquake Flood Decay and Collapse Security War and Conflict Poaching Erosion Invasive Species Epidemic animal disease Volcano Landslip Fire Theft and Looting Terrorism Deliberate destruction Illegal Logging Desertification Tourism pressures

12. Plan and prepare in advance Assess threat levels for: Impact on values Likelihood of happening Try to identify basic causes of threats and tackle those if possible Protection of heritage should be integrated with general risk management Risk management and climate change must be covered in Management Plans

13. Ensure that heritage is properly documented as basis for recovery Take preventive measures cf Roskilde Preventive measures should be proportionate to threat

16. Predicted effects of climate change Change in precipitation patterns Increase in frequency of warm episodes of El Nino-Southern Oscillation Change of frequency, intensity and seasonality of extreme weather events (eg droughts, fires, heavy rain/snow, floods, storms) Rise in sea level Increase of CO2 levels in atmosphere and dissolved in sea (Intergovernmental Panel on Climate Change (IPCC) 2001)

17. Predicted effects Increase by 1.4 to 5.8 degrees C by 2100 in global mean temperatures Intensification of hydrological cycle, with increased intensity of rainfall events but also more frequent droughts in arid/ semi-arid areas Increase of global sea level of 0.09 to 0.88m by 2100 Increased frequency of storm surges locally (European Environment Agency 2004)

18. Effects on cultural heritage – changing weather patterns Desertification Changing rainfall patterns impacting on earthen architecture Changes in soil moisture levels damaging buried archaeology Movement of species and pests Changing vegetation in planned landscapes

20. Effects on cultural heritage – severe weather events Storm damage by wind to buildings and landscapes Floods eg New Orleans, Dresden, Prague erosion

21. Effects on cultural heritage – sea level rise 15 out of 19 World Cities are by the coast Erosion and loss of land to sea In UK now policy for much of coast line is managed retreat Increased risk of flooding in combination with severe weather events, tidal surges etc, as happened in 1953

22. London 1 London has 4 World Heritage Sites, all on banks of Thames All vulnerable to floods from high tide/ storm surges in North Sea

23. London 2 Thames Barrier built in response to 1953 disaster Originally expected to be used 2/3 times each year Now being used 6/7 times per year By 2080’s, sea levels in Thames estuary 0.26 to 0.86m higher on average than 1961 - 1990

24. Reduced Summer Rainfall East of EnglandNW England Analysing the Combined Evidence

25. Sea Levels Rise/Storm Surge East of England NW England

26. Climate change indirect impacts on cultural heritage Societies also vulnerable to changes If climate change destroys particular combination of weather, land etc, basis of social system can go, particularly if already vulnerable for other reasons

27. Wider Implications of climate change Disasters related to climate change likely to occur more often Likely to occur as much in developed world as less developed Need also to consider long term changes leading to fundamental changes in landscape as well as immediate disaster

28. Remember the unexpected
