Box 4.2 Extensive risks in rural areas
Figure 4.1 Hydrometeorological disasters and losses in Colombia, 1970–2011
Figure 4.2 Proportion of disaster-affected inhabitants in urban and rural areas (expressed by rural index) and with unsatisfied basic needs (expressed by UBN index) during the 2010-2011 ENSO episode in Colombia
In Colombia, weather-related disasters are strongly correlated with ENSO episodes. But while the 2010–2011 La Nia was no stronger than others that had occurred in 1973–1976, 1998–2001 and 1988–89, the losses in terms of people affected and damage to housing were far greater (see Figure 4.1).
Most importantly, as Figure 4.2 shows, the proportion of the population affected in rural municipalities (rural index between 50 and 75) and with over 56 percent of unsatisfied basic needs was approximately 35 times greater than in the case of urban centres (rural index between 1 and 25) and with less than 27 percent of unsatisfied basic needs).
