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.

About 9,000 lives have been lost to the devastating earthquake in Nepal on April 25 and the powerful aftershock on May 12. A conference in Kathmandu on June 25 will bring Nepal together with its international partners to build the country back better and safer.
Unfortunately, this is not just a Nepal challenge. From Afghanistan to Bangladesh, much of South Asia is located in one of the highest seismically active regions in the world. More than 600 million people live along the fault-line across the Himalayan belt that runs through Afghanistan, Pakistan, India, Nepal and Bhutan.
As the people of Vanuatu begin the painstaking task of assessing the damage to their homes, businesses, and their communities in the wake of Cyclone Pam, another assessment is underway behind the scenes.
Given the intensity of the category 5 storm and the reports of severe damage, the World Bank Group is now exploring the possibility of a rapid insurance payout to the Government of Vanuatu under the Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI).
The Pacific catastrophe risk insurance pilot stands as an example of what’s available to protect countries against disaster risks. The innovative risk-pooling pilot determines payouts based on a rapid estimate of loss sustained through the use of a risk model.
The World Bank Group acts as an intermediary between Pacific Island countries and a group of reinsurance companies – Mitsui Sumitomo Insurance, Sompo Japan Insurance, Tokio Marine and Nichido Fire Insurance and Swiss Re. Under the program, Pacific Island countries – such as Vanuatu, the Cook Island, Marshall Islands, Samoa and Tonga – were able to gain access to aggregate risk insurance coverage of $43 million for the third (2014-2015) season of the pilot.
Japan, the World Bank Group, and the Secretariat of the Pacific Community (SPC) partnered with the Pacific Island nations to launch the pilot in 2013. Tonga was the first country to benefit from the payout in January 2014, receiving an immediate payment of US $1.27 million towards recovery from Cyclone Ian. The category 5 cyclone hit the island of Ha’apai, one of the most populated of Tonga’s 150 islands, causing $50 million in damages and losses (11 percent of the country’s GDP) and affected nearly 6,000 people.
Globally, direct financial losses from natural disasters are steadily increasing, having reached an average of $165 billion per year over the last 10 years, outstripping the amount of official development assistance almost every year. Increasing exposure from economic growth, and urbanization—as well as a changing climate—are driving costs even further upward. In such situations, governments often ﬁnd themselves faced with pressure to draw funding away from basic public services, or to divert funds from development programs.
Investing in Innovative Financial Solutions
The World Bank Group and other partners have been working together successfully on innovative efforts to scale up disaster risk finance. One important priority is harnessing the knowledge, expertise and capital of the private sector. Such partnerships in disaster risk assessment and financing can encourage the use of catastrophe models for the public good, stimulating investment in risk reduction and new risk-sharing arrangements in developing countries.
The Caribbean Catastrophe Risk Insurance Facility (CCRIF) is another good example of the benefits of pooled insurance schemes, and served as the model for the Pacific pilot. Launched in 2007, this first-ever multi-country risk pool today operates with sixteen participating countries, providing members with aggregate insurance coverage of over $600 million with 8 payments made over the last 8 years totaling of US$32 million. As a parametric sovereign risk transfer facility, it provides member countries with immediate liquidity following disasters.
We also know that better solutions for disaster risk management are powered by the innovation that results when engineers, sector specialists, and financial experts come together to work as a team. The close collaboration of experts in the World Bank Group has led to the rapid growth of the disaster risk finance field, which complements prevention and risk reduction.

With over 600 million people living along the fault-line across the Himalayan belt, South Asia’s earthquake exposure is very high. To further compound the problem, South Asia is urbanizing at a rapid pace and a significant growth in mega-cities, secondary and tertiary cities / towns is happening in high risk seismic zones. The region has experienced three large events over the past 15 years, the Bhuj earthquake of 2001, the Sumatra earthquake of 2004 (leading to the Asian tsunami) and the 2005 Kashmir earthquake. While there have been no major earthquakes these past 9 years, the region is akin to a ticking bomb for an earthquake disaster. Keeping this in mind, we mapped a region of 3000 Km radius from the center of India and analyzed earthquake events over a one-year period from May 2013 to May 2014. Only those earthquakes recorded by the United States Geological Survey’s global earthquake monitoring database (USGS) greater than 4.0 magnitude on the Richter scale were considered. We found a total of 1,247 recorded earthquake events. The story of a 1000 earthquakes was born and was a story that needed to be told.
We decided to create a video that would become an awareness tool and effectively communicate the risk the region faces. We deliberately steered away from talking about work being undertaken to reduce seismic risks or policy mechanisms that can be adopted. There are other mechanisms, mediums and opportunities to take that agenda forward. This is a short 90 seconds video and hopefully communicates the urgency of investing resources and efforts into earthquake safety. Increase the volume, enjoy, get scared. and then be prepared!
In the days following the January 12, 2010 earthquake in Haiti, the World Bank disaster risk management (DRM) community worked to assess the damage, and support the Haitian government plan and enact what would become a massive and protracted recovery from this profound disaster. Accurate and up to date maps of the country were an important component of these planning efforts. These maps came from an unexpected source, a global community of volunteer mappers, who, using their internet connections and access to satellite imagery, were able to contribute to mapping Haiti from their own homes.
Following the Haiti earthquake, the World Bank, Google, and several other entities made high-resolution imagery of the affected area available to the public. Over 600 individuals from the global OpenStreetMap (OSM) community began digitizing the imagery, tracing roads, building outlines, and other infrastructure, creating what quickly became the most detailed map of Port au Prince that had ever existed. Volunteers from 29 countries made about 1.2 million edits to the map, performing an estimated year of cartographic work in about 20 days. This effort catalyzed a rethinking of community mapping and open data within the World Bank and other international institutions.
Back in March 2014, I had the opportunity to be part of a World Bank team supporting the Tongan government to develop a reconstruction policy after Tropical Cyclone Ian hit earlier this year. To implement the policy, the Ministry of Infrastructure led a series of surveys to inform housing reconstruction. This post, which does not intend to be scientific or exhaustive, is to share some of the key lessons I learned from this experience.
Damage assessments are routine in the aftermath of disasters, but they differ depending on their objectives (Hallegatte, 2012 - pdf). A rapid survey in the wake of a disaster event could help to estimate grossly the direct human and economic losses and damages. This type of survey is best to capture the amplitude and the severity of the disaster. However, such survey could present some flaws, often because the survey will be conducted in a very short time frame with minimal design. On the other hand, a survey conducted a few months after the event is best to understand better the context of the disaster. It also allows a better design and better preparation. But, equally, such survey could include biases. For instance, the time lag between the event and the survey itself could create some level of challenges. Most likely, people would have started to fix their houses or have moved away from the affected area, and that will add a layer of complexity to the survey.
In the morning of January 11, 2014, after an early warning from the Department of Meteorology and the National Disaster Management Office on the upcoming category 5 tropical cyclone Ian, power and radio transmission went off on the Island of Ha’apai, one of the most populated among the 150 islands of the Tongan archipelago in the South Pacific.
The Pacific Islands are inherently prone to hazards due to their geographic location and small size. Each year Pacific Island countries experience damage and loss caused by natural disasters estimated at an average $284 million, or 1.7% of regional GDP (World Bank 2013). In the coming decades, climate change is expected to make things worse through sea level rise and more intense cyclones.
In 2011, Thailand suffered the worst floods in half a century. The flood crisis impacted more than 13 million people. About 97,000 houses were damaged and entire villages and cities were under water for months.

Three years later, Thailand has been able to deal with the worst of the impacts but some of the poorest households are still struggling to recover. We visited 10 affected communities in Ayutthaya and Nakhon Sawan as part of the supervision of the Community-based Livelihood Support for Urban Poor Project (SUP). We could still see the water marks on their walls, damaged ceilings, and wobbly structures. The unrepaired houses stuck out but just as striking was the strong sense of community in the area. We were reminded that villagers came together to overcome the worst natural disaster most of them ever witnessed in their lives.
The flooding led to better disaster risk management in the neighborhoods that are most at risk. Local governments have taken the lead. But the disaster has also, just as importantly, mobilized ordinary citizens in some of the most deprived communities. Here are some of their stories:
Losses due to disasters to human and physical capital are on the rise across the world. Over the past 30 years, total losses have tripled, amounting to $3.5 trillion. While the majority of these losses were experienced in OECD countries, the trend is increasingly moving towards losses in rapidly growing states.
In a sense, increasing risk and losses caused by disaster are the byproduct of a positive trend - strong development gains and economic growth. This is because disaster loss is a function of the amount of human and physical assets exposed to seismic or hydrometeorological hazards, and the level of vulnerability of the assets. The richer a country gets, the more assets it builds or acquires, and therefore the more losses it potentially faces.
Rapid development across South Asia signals the need to commit greater efforts to increase resilience to disaster and climate risk. It also requires governments to develop a strategy to both protect against events today and to develop strategies to address the losses of the future. This is a challenge somewhat unique to South Asia. The losses of today, predominantly rural flooding that impacts wide swaths of vulnerable populations, will begin to diminish in relative importance to the losses of the future.

Increasing flood risks create a major political and institutional challenge for the world’s coastal cities, as ambitious and proactive action at the local level over the next decades will be needed to avoid large-scale flood disasters. However, the implementation of flood risk management policies meets many obstacles.
In a recent study written with colleagues Colin Green, Robert Nicholls and Jan Corfee-Morlot as part of an OECD project on urban vulnerability, we estimate how flood risks could change in the future in 136 coastal cities, in response to increasing population and wealth, local environmental change, and climate change. We find that because current flood defenses and urbanization patterns have been designed for past environmental conditions, even a moderate change in sea level is sufficient to make them inadequate, thus magnifying flood losses to catastrophic levels. If no action is taken to reduce flood vulnerability, most coastal cities would become inhospitable and dangerous places to live, with annual losses in excess of US$1 trillion dollars.
What can be done?
Our analysis suggests that upgrading defenses could mitigate these losses and the impacts of rising sea levels. However, these upgrades need to include a package of risk management policies. First, coastal defenses should make use of the protection the environment can offer for free: Marshes, seagrass beds, coastal and kelp forests, and coral reefs provide natural buffers that absorb the energy from waves and storms, making it easier and cheaper to protect urban development. In addition artificial constructions are also required to provide full protection. We are not only talking about dykes: a city surrounded by dykes will need pumping systems to drain rainfall water, and a harbor will need moving barriers to let ships in and out of the port.
