The death toll from Cyclone Idai that ripped into Mozambique, Zimbabwe, and Malawi in March 2019 is now above 1,000, with damages estimated at $2 billion. In 2018, more than 10,000 people lost their lives in disasters (with $225 billion of economic losses). Approximately 79 percent of fatalities occurred in the Asia Pacific region, including the catastrophic earthquake and tsunami in Indonesia’s Sulawesi Island. In fact,
With climate change increasing the probability of extreme weather events and the explosive and largely unplanned growth of populations and assets in the developing world, the process of post-disaster rebuilding of communities offers a stark choice: The right policy choices could set economies, cities, towns and villages, and neighborhoods on a resilient, sustainable path, and, unfortunately, the wrong policies would inevitably lead to fraud, waste, corruption, delays, and failure.
Several studies by the World Bank and the IMF, including a global review by my colleagues and me, have looked at the reconstruction process after major disasters over the past several decades. To my mind, the four of the most important lessons we have learned are:
1. The macroeconomic growth impacts of major weather disasters are negative, large, and persistent, but fiscal impacts can be mitigated through good policy.
- Integrating disaster risks into the medium-term fiscal framework, fixing the budgetary “plumbing” that enables resources to hit the ground quickly, e.g. by incorporating some escape clauses for disasters in budget laws and fiscal rules, or streamlining the process for preparing and passing a revised budget;
- Having emergency procurement procedures in place ex-ante; and
- Generating fiscal space to finance disaster response programs, by transferring residual risks to the private sector – such as Mexico’s public asset insurance program FONDEN – or buying reinsurance in international capital markets, such as the Pacific Catastrophe Risk and Financing Initiative.
2. The most vulnerable poor households, children, and the disabled need special attention and protection.
It is an empirical fact that In the Philippines, over the last two decades, 15 times as many infants have died in the 24 months following typhoon events as died in the typhoons themselves; most of them were infant girls. In Niger, regardless of the birth location, children born during a drought are more than twice as likely to be malnourished between the ages of one and two.
4. Preparedness is the best investment any government can make.
Which brings us to our “half lesson”: each disaster and its context is unique.
While the four lessons above are important, balance trade-offs between speed and fiduciary controls, emergency versus regular procurement, urban versus rural settings, on versus off budget expenditures, and most importantly, immediate rebuilding versus long-term planning.Post-disaster reconstruction strategies should also
