36. The PAR “crunch” model is a basic approach, with limitations discussed in the book. The main limits are dealt with through the much more complex “Access” model, dealt with in Chapter 3 of At Risk . The next slide is the basic diagram of the Access model.
39. Regional distribution is uneven Environment provides: Risks Opportunities Hazards: floods, earthquakes, hurricanes, eruptions Production resources: land, water, minerals, energy Class - Gender - Ethnicity Unequal access to opportunities and unequal exposure to hazards Social systems and power relations Political and economic systems – national and international People do not separate these! They are often willing to live in unsafe places

51. Situation report after the Indian Ocean tsunami (26 December 2004): “ Although devastating, the tsunami disaster is not likely to have a catastrophic impact on economies in the region. This is mainly because the areas affected, for the most part, were not industrial centers but poor fishing villages and small coastal towns, places of limited economic value.” This assessment by a risk analysis corporation leaves out the community...

Notes de l'éditeur
Notes: The source for political violence data is: Sivard, R. 2001, World military and social expenditures , Washington DC: World Priorities. For all other causes, data is summarised from that available at www.cred.be/emdat The figure for slow-onset disasters has been increased by us to an estimate of 70 million, much higher than the official data, which would give a total of around 18 million. This is to compensate for large-scale under-reporting of deaths from drought and famine. There are several reasons why this can occur. For instance, it is often the case that governments conceal or refuse to acknowledge famine for political reasons. The ‘Great Leap’ famine in China (1958-61) was officially denied for more than twenty years, and then low estimates put the number of deaths at 13 million and higher ones at up to 30 million or more (see Chapter 4, At Risk ). A further problem is that sometimes recorded deaths in famine are limited to those who die in officially managed feeding or refugee camps. Many more are likely to die without records at home or in other settlements.
