Four propositions drawn from 60 years of natural hazard and reconstruction research provide a comparative and historical perspective on the reconstruction of New Orleans after Hurricane Katrina. Decisions taken over its 288-year history that have made New Orleans so vulnerable to Katrina reflect a long-term pattern of societal response to hazard events--reducing consequences to relatively frequent events, and increasing vulnerability to very large and rare events. Thus Katrina's consequences for New Orleans were truly catastrophic--accounting for most of the estimated 1,570 deaths of Louisiana residents and $40-50 billion in monetary losses. A comparative sequence and timing of recovery provides a calendar of historical experience against which to gauge progress in reconstruction. Using this calendar, the emergency post-disaster period appears to be longer in duration than that of any other studied disaster. The restoration period, the time taken to restore urban services for the smaller population, is in keeping with or ahead of historical experience. The effort to reconstruct the physical environment and urban infrastructure is likely to take 8-11 years. Conflicting policy goals for reconstruction of rapid recovery, safety, betterment, and equity are already evident. Actions taken demonstrate the rush to rebuild the familiar in contrast to planning efforts that emphasize betterment. Because disasters tend to accelerate existing economic, social, and political trends, the large losses in housing, population, and employment after Katrina are likely to persist and, at best, only partly recover. However, the possibility of breaking free of this gloomy trajectory is feasible and has some historical precedent.
从60年的自然灾害与重建研究中得出的四个命题,为卡特里娜飓风过后新奥尔良的重建提供了一个比较性的历史视角。在新奥尔良288年历史中做出的决策,使这座城市对卡特里娜飓风如此脆弱,反映了社会对灾害事件的长期应对模式——减少对相对频繁事件的影响,却增加了对非常重大且罕见事件的脆弱性。因此,卡特里娜飓风给新奥尔良带来的后果是灾难性的——造成了路易斯安那州居民估计1570人死亡中的大部分,以及400亿至500亿美元的经济损失。恢复的比较序列和时间安排提供了一个历史经验日程表,据此可以衡量重建进展。根据这个日程表,灾后应急期的持续时间似乎比其他任何研究过的灾害都要长。恢复时期,即恢复为较少人口提供城市服务所需的时间,与历史经验相符或领先于历史经验。重建物质环境和城市基础设施的努力可能需要8至11年。重建快速恢复、安全、改善和公平等相互冲突的政策目标已经很明显。所采取的行动表明,急于重建熟悉的事物,与强调改善的规划努力形成对比。由于灾害往往会加速现有的经济、社会和政治趋势,卡特里娜飓风过后住房、人口和就业方面的巨大损失可能会持续存在,充其量也只能部分恢复。然而,摆脱这种黯淡轨迹的可能性是可行的,并且有一些历史先例。
