Disaster Resilience

The disaster risk management funding gap in fragile, conflict and violence-affected countries

Thomas Lennartz's picture

Saddled with weak political systems and ravaged by strife, fragile, conflict and violence-affected countries suffer some of the largest losses from natural disasters. According to the Overseas Development Institute, 58 percent of deaths from disasters between 2004 and 2014 occurred in countries with fragile contexts. Across the globe, rapid urbanization and climate change are further increasing the exposure and vulnerability of these communities to natural hazards.


Yet, even as people in fragile, conflict and violence-affected countries struggle to cope with the growing dangers from natural disasters, the international donor community has been slow to respond, explains Thomas Lennartz of the Global Facility for Disaster Reduction and Recovery (GFDRR). Tellingly between 2005 and 2010, for every $100 spent on humanitarian assistance to these countries, only $1.30 was spent on disaster risk management (DRM).
 
So what can be done to help close this funding gap? In this video from the 2018 Understanding Risk Forum, hosted by GFDRR and the World Bank, Lennartz offers his take – and shares a few insights on GFDRR’s emerging DRM portfolio in fragile, conflict and violence-affected countries.

On October 4, 2016, category 4 Hurricane Matthew struck the southern part of Haiti. Strong winds and rain triggered heavy flooding and landslides that resulted in 500 fatalities, along with widespread infrastructure damage and economic loss. The hurricane caused the collapse of the Ladigue Bridge, a vital asset connecting the southern peninsula of Haiti to the capital city and the rest of the country. The collapse left 1.4 million people completely isolated, making it extremely hard to deliver the aid and humanitarian assistance they needed. Overall damage and losses were equivalent to 32% of GDP, with transport accounting for almost a fifth of the total.
 
Haiti is among the countries that are most vulnerable to natural disasters including hurricanes, floods, and earthquakes—the result of a combination of factors that include high exposure to natural hazards, vulnerable infrastructure, environmental degradation, institutional fragility, and a lack of adequate investment in resilience. In Haiti, 80% of people and goods are transported by road. First aid and humanitarian resources, often concentrated in Port-au-Prince, need to transit through congested and sometimes inaccessible roads to reach affected areas. In that context, strengthening and building resilient infrastructure is key.
 
Since 2008, the World Bank has supported the reconstruction of 15 major bridges and stabilized 300 kilometers of roads to enhance the resilience of Haiti’s transport network. One of the most significant innovations that came out of this effort was the adoption of standardized emergency bridges that can be assembled within 2- 3 months from pre-designed and interchangeable components.

Globally, up to 1.4 million people are moving into urban areas per week, and estimates show that nearly 1 billion new dwelling units will be built by 2050 to support this growing population. The way we build our cities today directly impacts the safety of future generations.

So how do we ensure that we are building healthy, safe, and resilient cities?

The concentration of population in cities and their exposure to seismic hazards constitute one of the greatest disaster risks facing Peru and Ecuador. In 2007, a magnitude 8.0 earthquake along the southern coast of Peru claimed the lives of 520 people and destroyed countless buildings. The most recent earthquake in Ecuador, in 2016, left more than 200 dead and many others injured.
 
Of course, these risks are not exclusive to Latin America. Considered one of the most earthquake-prone countries in the world, Japan has developed unparalleled experience in seismic resilience. The transport sector has been an integral part of the way the country manages earthquake risk— which makes perfect sense when you consider the potential consequences of a seismic event on transport infrastructure, operations, and passenger safety.

Resilience in urban transport: what have we learned from Super Storm Sandy and the New York City Subway?

Back in 2012, a storm surge triggered by Super Storm Sandy caused extensive damage across the New York City (NYC)-New Jersey (NJ) Metropolitan Area, and wreaked havoc on the city’s urban rail system.

As reported by the Metropolitan Transportation Authority (MTA), the subway suffered at least $5 billion worth of damage to stations, tunnels and electrical/signaling systems. The Port Authority Trans-Hudson network (PATH) connecting NYC to NJ was also severely affected, with losses valued at approximately $871 million, including 85 rail cars damaged.

In the face of adversity, various public institutions in charge of urban rail operations are leading the way to repair damaged infrastructure (“fix”), protect assets from future similar disasters (“fortify”), restore services to millions of commuters and rethink the standards for future investments.

NYC and NJ believe that disasters will only become more frequent and intense. Their experience provides some valuable lessons for cities around the world on how to respond to disasters and prepare urban rail systems to cope with a changing climate.

“This storm has already left hundreds of thousands without power along the Texas coast. And there are reports of significant damage to buildings in Rockport, Texas, near where the storm made landfall Friday night. At a press conference Saturday afternoon, Texas Governor Greg Abbott said it may be ‘several days before outages can be addressed’ due to continued high winds.” - VOX

What is Future-Proofing?

Future-proofing is described as the process of anticipating the future and developing methods to mitigate its impacts. Future-proofing when considered in infrastructure Public-Private Partnerships (PPPs) adds a layer of resilience to projects that will ensure their sustainability and longevity.

What El Niño has taught us about infrastructure resilience

The rains in northern Peru have been 10 times stronger than usual this year, leading to floods, landslides and a declaration of a state of emergency in 10 regions in the country. Together with the human and economic toll, these downpours have inflicted tremendous damage to transport infrastructure with added and serious consequences on people’s lives.

These heavy rains are blamed on El Niño, a natural phenomenon characterized by an unusual warming of the sea surface temperature in the central and eastern equatorial Pacific Ocean. This phenomenon occurs every two to seven years, and lasts about 18 months at a time. El Niño significantly disrupts precipitation and wind patterns, giving rise to extreme weather events around the planet.

In Peru, this translates into rising temperatures along the north coast and intense rainfall, typically shortly before Christmas. That’s also when “huaicos” appear. “Huaico,” a word that comes from the Quechua language (wayq’u), refers to the enormous masses of mud and rocks carried by torrential rains from the Andes into rivers, causing them to overflow. These mudslides result from a combination of several natural factors including heavy rains, steep slopes, scarce vegetation, to name a few. But human factors also come into play and exacerbate their impact. That includes, in particular, the construction of human settlements in flood-prone basins or the absence of a comprehensive approach to disaster risk management.

This year’s floods are said to be comparable to those caused by El Niño in 1997-1998, one of the largest natural disasters in recent history, which claimed the lives of 374 people and caused US$1.2 billion worth of damages (data provided by the Peruvian National Institute of Civil Defense).

Climate and disaster risk in transport: No data? No problem!

Frederico Pedroso's picture
Development professionals often complain about the absence of good-quality data in disaster-prone areas, which limits their ability to inform projects through quantitative models and detailed analysis.
 
Technological progress, however, is quickly creating new ways for governments and development agencies to overcome data scarcity. In Belize, the World Bank has partnered with the government to develop an innovative approach and inform climate-resilient road investments through the combination of creativity, on-the-ground experience, and strategic data collection.
 
Underdeveloped infrastructure, particularly in the transport sector, is a key constraint to disaster risk mitigation and economic growth in Belize. The road network is particularly vulnerable due to the lack of redundancy and exposure to natural hazards (mostly flooding). In the absence of alternative routes, any weather-related road closure can cut access and severely disrupt economic and social movement.
 
In 2012, the government made climate resilience one of their key policy priorities, and enlisted the World Bank’s help in developing a program to reduce climate vulnerability, with a specific focus on the road network. The institution answered the call and assembled a team of experts that brought a wide range of expertise, along with experience from other climate resilience interventions throughout the Caribbean. The program was supported by Africa, Caribbean and Pacific (ACP) European Union funds, managed by the Global Facility for Disaster Reduction and Recovery (GFDRR).
 
Our strategy to address data scarcity in Belize involves three successive, closely related steps.

To build resilient cities, we must treat substandard housing as a life-or-death emergency

The scene is as familiar as it is tragic: A devastating hurricane or earthquake strikes a populated area in a poor country, inflicting a high number of casualties, overwhelming the resources and capacity of rescue teams and hospital emergency rooms. First responders must resort to “triage” – the medical strategy of maximizing the efficient use of existing resources to save lives, while minimizing the number of deaths. 

But if governments could apply triage to substandard housing, medical triage would be a much less frequent occurrence – because in the developing world, it is mainly housing that kills people, not disasters.
 
From the 2017 Global Platform for Disaster Risk Reduction to the 2017 Urban Resilience Summit, practitioners and policymakers have increasingly focused their discussions on how we can boost the resilience of urban areas.

But this is a problem with a well-known solution: Resilient cities require resilient housing.

To make housing more resilient, cities need to focus on two different but complementary angles: upgrading the existing housing stock, where most the poor live, while making sure that new construction is built safe, particularly for natural disasters. After all, if floods or earthquakes do not distinguish between old and new homes, why should policymakers? It is time for resilience to become part of the definition of “decent, affordable, and safe housing.”

 

The “plastic bridge”: a low-cost, high-impact solution to address climate risk

Bridges are critical links in the transport network. In their position across waterways, they are exposed to the full effects of flooding and landslides, and are often the first pieces of infrastructure to be damaged in the event of a disaster. They also typically take weeks or months to repair.  Besides causing expensive damage to the infrastructure itself, disruptions in connectivity also have a much broader impact on economic productivity and people’s ability to access essential services. As many places are expected to witness more intense and frequent rainfall as a result of climate change, the risk to bridges will only worsen: more rainfall will lead to bigger river flows and more damage to bridges, especially those designed to handle smaller storms.

At each end of a bridges is a structure which supports the weight of the deck. These are known as abutments, and they are often the first part of the bridge to fail. Blockage of the main channel by debris can cause water to look for the path of least resistance around the sides of the bridges, thus placing the abutments at risk.

Traditional bridge construction requires the installation of piles for the foundations of abutments—a lengthy and expensive process that involves specialist materials, skills and equipment.

But there is another promising solution: Geosynthetic Reinforced Soil (GRS) abutments. These allow for rapid and resilient construction of bridge abutments using locally available materials, without specialized equipment. With GRS, bridges can be constructed in as little as five days (Von Handorf, 2013) and at a cost 30-50% lower than traditional approaches (Tonkin and Taylor, 2016) .

GRS abutments are based on ‘geogrids,’ a high density mesh made out of polyethylene (plastic). Layers of soil and geogrid are combined to create a solid foundation for the bridge deck. Construction can be completed with basic earthmoving and compaction equipment, and a range of local fill materials can be used with guidance from geotechnical specialists.
