New project uses satellites for rapid assessment of flood response costs

Antoine Bavandi's picture

High-risk areas for natural disasters are home to 5 billion out of the 7 billion total people on our planet.

Overall global losses from natural disasters such as floods, landslides or earthquakes amount to about $300 billion annually. A rapid and early response is key to immediately address the loss of human life, property, infrastructure and business activity.

Severe flooding occurred during the 2011 monsoon season in Thailand, resulting in more than 800 deaths. About 14 million people were affected, mostly in the northern region and in the Bangkok metropolitan area.

After such natural disasters, it is important that governments rapidly address recovery efforts and manage the financial aspects of the disaster’s impacts. Natural disasters can cause fiscal volatility for national governments because of sudden, unexpected expenditures required during and after an event.

This is especially critical in emerging-market economies, such as those in Southeast Asia, which have chronic exposure to natural disasters. To conserve and sustain development gains and analyze societal and financial risks at a national or regional scale, it is also critical to understand the impacts of these disasters and their implications at the socioeconomic, institutional and environmental level.
 
New project to monitor and evaluate flood severity

Financed by the Rockefeller Foundation, this World Bank Group’s Disaster Risk Financing and Insurance Program (DRFIP) and Columbia University’s Earth Institute joint project aims to define an operational framework for the rapid assessment of flood response costs on a national scale.  Bangladesh and Thailand serve as the initial demonstration cases, which will be expanded to other Southeast Asian countries such as Cambodia, Lao PDR, Myanmar and Vietnam.

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.

On the road to resilience: Reducing disaster and climate risk in Africa

Natural disasters—such as droughts, floods, landslides, and storms—are a regular occurrence, but climate change is increasing the frequency and intensity of such weather-related hazards. Since 1970, Africa has experienced more than 2,000 natural disasters, with just under half taking place in the last decade. During this time, natural disasters have affected over 460 million people and resulted in more than 880,000 casualties. In addition, it is estimated that by 2030, up to 118 million extremely poor people (living below $1.25/day) will be exposed to drought, floods, and extreme heat in Africa. In areas of recurrent disasters, this hampers growth and makes it harder for the poor to escape poverty.

Using technology to stay ahead of disaster risk

We’re witnessing an unprecedented uptick in record-breaking storms. In October last year, Hurricane Patricia came ashore in Mexico with record breaking 200 miles per hour winds. A few months later on the other side of the world, Cyclone Winston broke records for Pacific basin wind speeds, destroying parts of mainland Fiji with 180 miles per hour winds. More recently, Cyclone Fantala became the most powerful storm in the Indian Ocean ever recorded.
 
Experts agree that its activities by people which are increasing the severity of storms like these. Climate change isn’t just projected to increase the intensity of hurricanes and cyclones, but a whole other range of other natural hazards, like droughts, floods, storms, and heat waves.

How can small island states become more resilient to natural disasters and climate risk?

Ede Ijjasz-Vasquez's picture
Small Island States are particularly vulnerable to the impact of climate change and natural disasters. In fact, 2/3 of the countries that have been most severely impacted by disasters are small island nations, which have lost between 1 and 9% of GDP annually due to weather extremes and other catastrophes. The severity and recurrence of disasters makes it hard for those countries to recover, and seriously undermines ongoing development efforts.
 
The World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) are actively working with small island states to mitigate the impact of natural disasters and climate risk, including through their joint Small Island States Resilience Initiative. World Bank Senior Director Ede Ijjasz-Vasquez and GFDRR's Sofia Bettencourt tell us more.

In the face of disaster, resilient communities are just as important as resilient infrastructure

What does it take to prevent or mitigate the impact of natural disasters?
 
For many, disaster resilience is all about better infrastructure, efficient early warning systems, and stronger institutions. While those aspects are obviously crucial, we shouldn’t overlook the role of communities themselves in preparing for and responding to disasters. After all, the success of both preparedness and recovery efforts depends largely on local residents' ability to anticipate risk, on their relationship with local and national authorities, and on the way they organize themselves when disaster strikes. In the aftermath of a catastrophe, rebuilding not just the physical environment but also the livelihoods of people is also essential, including through effective social protection systems and safety nets.
 
In this video, Senior Social Development Specialist Margaret Arnold explains how the World Bank is working with client countries and local communities to bring the social dimension of disaster risk management to the forefront.

How can we help countries share their own development knowledge? Insights from Japan

Ede Ijjasz-Vasquez's picture
To help clients achieve their development objectives, the World Bank has established knowledge-sharing "hubs" in countries that have gained valuable experience from dealing with their own challenges. That is the rationale behind the creation of a Disaster Risk Management (DRM) Hub and Tokyo Development Learning Center (TDLC) in Japan, a country that has developed unparalleled expertise in disaster resilience, quality infrastructure, and sustainable urban development. In this video, Keiko Sakoda Kaneda (DRM Hub) and Daniel Levine (TDLC) elaborate on some of the key elements of their work program, and explain how they collaborate with development partners from around the world.

Focus on the “day before” to better plan for the “day after”

Lessons learned over time from post-conflict recovery and reconstruction efforts reflect the need to reinforce stabilization immediately following the end of a conflict.

Being ready in advance with a recovery and reconstruction plan is one way to ensure that critical interventions can be implemented quickly following the cessation of hostilities.This can be achieved to a large extent by coordinating with humanitarian efforts in the recovery continuum during active conflict.
 
Such a plan helps to identify actionable opportunities that can help to support local-level recovery. This includes immediate improvements in services and enhancing livelihood opportunities essential to establishing popular confidence in state institutions and to fostering social cohesion.

Fragility, conflict, and natural disasters – a ‘one-size fits all’ approach to resilience?

It’s a simple yet essential idea: war and disaster are linked, and these links must be examined to improve the lives of millions of people around the world.

Alarmingly, the total number of disaster events – and the economic losses associated with those events – keep increasing. This trend has been driven by population growth, urbanization, and climate change, leading to increasing economic losses of $150-$200 billion each year, up from $50 billion in the 1980s. But here is another piece of information: more than half of people impacted by natural hazards lived in fragile or conflict-affected states.

What El Niño teaches us about climate resilience

Francis Ghesquiere's picture
It was recorded by the Spanish conquistadors, and triggered famines that have been linked to China’s 1901 Boxer Rebellion and even the French revolution.

Named by Peruvian fishermen because of its tendency to appear around Christmastime, El Niño is the planet’s most large-scale and recurring mode of climate variability. Every 2-7 years, a slackening of trade winds that push sun-warmed water across the Pacific contributes to a rise in water temperature across large parts of the ocean. As the heat rises, a global pattern of weather changes ensues, triggering heat waves in many tropical regions and extreme drought or rainfall in others.

The fact that we are undergoing a major El Niño event should cause major concern and requires mobilization now. Already, eight provinces in the Philippines are in a state of emergency due to drought; rice farmers in Vietnam and Thailand have left fields unplanted due to weak rains; and 42,000 people have been displaced by floods in Somalia.

And this is before the event reaches its peak. Meteorologists see a 95% chance of the El Niño lasting into 2016, with its most extreme effects arriving between now and March. Coastal regions of Latin America are braced for major floods; India is dealing with a 14% deficit in the recent monsoon rains; and poor rainfalls could add to insecurity in several of Africa’s fragile states. Indeed, Berkeley Professor Soloman Hsiang has used historical data to demonstrate that the likelihood of new conflict outbreaks in tropical regions doubles from 3% to 6% in an El Niño year.

But despite its thousand-year history, the devastation associated with El Niño is not inevitable. Progress made by many other countries since the last major event, in 1997-98, shows that we can get a grip on its effect – and others caused by climate trends.
