Building Resilience To Natural Disasters An Application To Small Developing States

We present a dynamic small open economy model to explore the macroeconomic impact of natural disasters. In addition to permanent damages to public and private capital, the disaster causes temporary losses of productivity, inefficiencies during the reconstruction process, and damages to the sovereign's creditworthiness. We use the model to study the debt sustainability concerns that arise from the need to rebuild public infrastructure over the medium term and analyze the feasibility of ex ante policies, such as building adaptation infrastructure and fiscal buffers, and contrast these policies with the post-disaster support provided by donors. Investing in resilient infrastructure may prove useful, in particular if it is viewed as complementary to standard infrastructure, because it raises the marginal product of private capital, crowding in private investment, while helping withstand the impact of the natural disaster. In an application to Vanuatu, we find that donors should provide an additional 50% of pre-cyclone GDP in grants to be spent over the following 15 years to ensure public debt remains sustainable following Cyclone Pam. Helping the government build resilience on the other hand, reduces the risk of debt distress and at lower cost for donors.

Small developing states are disproportionately vulnerable to natural disasters. On average, the annual cost of disasters for small states is nearly 2 percent of GDP—more than four times that for larger countries. This reflects a higher frequency of disasters, adjusted for land area, as well as greater vulnerability to severe disasters. About 9 percent of disasters in small states involve damage of more than 30 percent of GDP, compared to less than 1 percent for larger states. Greater exposure to disasters has important macroeconomic effects on small states, resulting in lower investment, lower GDP per capita, higher poverty, and a more volatile revenue base.

Some small states enjoy relatively high GDP per capita –giving the impression of economic strength – when in reality these economies are fragile and disproportionately affected by adverse economic shocks, natural disasters and extreme weather events. The Commonwealth resilience framework has been developed to identify both the national policies required to build resilience and the areas in which regional and international development partners can provide support. This study refines and expands the framework to cover areas such as governance, environmental management and social development. It proposes policy measures for building resilience and ways in which the resilience framework for small states can be embedded in national planning to help stakeholders to agree priority areas for policy intervention.

Storms, hurricanes, and cyclones have been a feature of life on Small Island Developing States (SIDS) for centuries. But climate change is now increasing the intensity of these disasters, as well as creating new developmental challenges - like rising sea levels and increasing ocean acidity - ...

This paper discusses how countries vulnerable to natural disasters can reduce the associated human and economic cost. Building on earlier work by IMF staff, the paper views disaster risk management through the lens of a three-pillar strategy for building structural, financial, and post-disaster (including social) resilience. A coherent disaster resilience strategy, based on a diagnostic of risks and cost-effective responses, can provide a road map for how to tackle disaster related vulnerabilities. It can also help mobilize much-needed support from the international community.

Infrastructure—electricity, telecommunications, roads, water, and sanitation—are central to people’s lives. Without it, they cannot make a living, stay healthy, and maintain a good quality of life. Access to basic infrastructure is also a key driver of economic development. This report lays out a framework for understanding infrastructure resilience - the ability of infrastructure systems to function and meet users’ needs during and after a natural hazard. It focuses on four infrastructure systems that are essential to economic activity and people’s well-being: power systems, including the generation, transmission, and distribution of electricity; water and sanitation—especially water utilities; transport systems—multiple modes such as road, rail, waterway, and airports, and multiple scales, including urban transit and rural access; and telecommunications, including telephone and Internet connections.

Small Developing States (SDS) face substantial challenges in achieving sustainable development. Many of these challenges relate to the small size and limited diversification of their economies. SDS are also among the most vulnerable countries to the impact of climate change and natural disasters. Meeting SDS sustainable development goals goes hand-in-hand with building their climate resilience. But the additional costs to meet development and resilience objectives are substantial and difficult to finance. This work adapts the IMF SDG Costing methodology to capture the unique characteristics and challenges of climate-vulnerable SDS. It also zooms into financing options, estimating domestic tax potential and discussing the possibility of accessing ‘climate funds.’
