Rebuilding after natural disasters: What is the solution?

Within the last week, the Southeast Asia has been hit with some devastating natural disasters The Philippines has had massive flooding at historical levels. Indonesia and Samoa both were hit with tsunamis almost five years after the one that hit the South East Asia region causing hundreds of thousands deaths and mass destruction. Throughout history, we have faced natural disasters that scale from large to small and for the most part we have recovered from them. There is an instinctive desire of mankind to tame mother nature by rebuilding what is destroyed. However, as we have asked here in the US after Katrina, at what cost should we continue to vicious this cycle of destruction and rebuilding. Sooner or later the economics will not make sense. Perhaps the free market will decide this for us by making insurance more costly and property values drop in these natural disaster prone areas or, in certain countries, the government either forces people to abandon the land or the government ceases to provide assistance. This raises the question that if any of these events occur, where do the people go. For most part, people stay put because they have no other choice or deep loyalty and connection with their home; however, there are many cases in which they go to other places seeking safety from these repeated destructive displays of mother nature's power. This happened in New Orleans where the population had decreased considerable and it slowly is getting back to pre-Katrina numbers. The issues we face today will be placed in the forefront as more of these natural disasters occur with more violent destruction. Governments need to start addressing the possibility that either people cannot or will not want to return to the zones of devastation. In that case, we need a process to handle this group of people and not leave it to the NGOs or other international organizations with limited resources. We should plan now when we have time to prepare as opposed to when the event occurs because, as we have demonstrated with Katrina, when we react to an event as opposed prepare for it, the results lead to further death to the population that is seeking assistance.
