Abstract

Globally, more than 130 million people are estimated to be in food crisis. These humanitarian disasters are associated with severe impacts on livelihoods that can reverse years of development gains. The existing outlooks of crisis-affected populations rely on expert assessment of evidence and are limited in their temporal frequency and ability to look beyond several months. This paper presents a statistical foresting approach to predict the outbreak of food crises with sufficient lead time for preventive action. Different use cases are explored related to possible alternative targeting policies and the levels at which finance is typically unlocked. The results indicate that, particularly at longer forecasting horizons, the statistical predictions compare favorably to expert-based outlooks. The paper concludes that statistical models demonstrate good ability to detect future outbreaks of food crises and that using statistical forecasting approaches may help increase lead time for action.

Abstract

National governments are key actors in managing the impacts of extreme weather events, yet many highly exposed developing countries - faced with exhausted tax bases, high levels of indebtedness, and limited donor assistance - have been unable to raise sufficient and timely capital to replace or repair damaged infrastructure and restore livelihoods after major disasters. Such financial vulnerability hampers development and exacerbates poverty. Based on the record of the past 30 years, this paper finds many developing countries, in particular small island states, to be highly financially vulnerable, and experiencing a resource gap (net disaster losses exceed all available financing sources) for events that occur with a probability of 2 percent or higher. This has three main implications. First, efforts to reduce risk need to be ramped-up to lessen the serious human and financial burdens. Second, contrary to the well-known Arrow-Lind theorem, there is a case for country risk aversion implying that disaster risks faced by some governments cannot be absorbed without major difficulty. Risk aversion entails the ex ante financing of losses and relief expenditure through calamity funds, regional insurance pools, or contingent credit arrangements. Third, financially vulnerable (and generally poor) countries are unlikely to be able to implement pre-disaster risk financing instruments themselves, and thus require technical and financial assistance from the donor community. The cost estimates of financial vulnerability - based on today's climate - inform the design of "climate insurance funds" to absorb high levels of sovereign risk and are found to be in the lower billions of dollars annually, which represents a baseline for the incremental costs arising from future climate change.

Abstract

In recent years, typhoons have struck the Philippines and Vanuatu; earthquakes have rocked Haiti, Pakistan, and Nepal; floods have swept through Pakistan and Mozambique; droughts have hit Ethiopia, Kenya, and Somalia; and more. All led to loss of life and loss of livelihoods, and recovery will take years. One of the likely effects of climate change is to increase the likelihood of the type of extreme weather events that seems to cause these disasters. But do extreme events have to turn into disasters with huge loss of life and suffering? 'Dull Disasters?' harnesses lessons from finance, political science, economics, psychology, and the natural sciences to show how countries and their partners can be far better prepared to deal with disasters.
