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.

To celebrate World Environment Day, hundreds of Freetonians came together to plant a tree in honor of the more than 1,000 people killed and missing after devastating landslides and floods tore through Freetown less than a year ago. The landslide and flood waters ripped through the capital city with tremendous energy, destroying everything in its path. It was reported that a huge wave of boulders, building debris and mud cascaded down the river channel immediately after the landslide. The disaster affected more than 6,000 people and caused significant destruction and damage to critical infrastructure.

Ponto-cho mapIt is 7:45 p.m. in Ponto-cho, the historic narrow alley at the core of the Japanese city of Kyoto. Close to the Kaburenjo Theater – where still today Geikos and Maikos (Kyoto Geishas) practice their dances and performances – the traditional adjoining buildings with restaurants and shops are full of guests. Local people, tourists, students… On this Saturday in mid-April, the warm weather brings a lot of people to the streets nearby.

At 7:46 p.m., a M 5.1 earthquake strikes. Seven seconds of swaying. It doesn’t cause major damage, but it is enough to spread panic among a group of tourists. Screams, shoving, confusion… drinks spill, candles fall, people rush.

At 7:49 p.m., the fire starts spreading through the old wooden structures, also threatening the historic theater. Access is difficult due to the narrow streets and panicking crowd.

What happens next?

It could be a fire in the Ponto-cho traditional alley. It could be an earthquake shaking the historic center of Kathmandu (Nepal), the archaeological site of Bagan (Myanmar), or the historic town of Amatrice (Italy). It could be Typhoon Haiyan in the Philippines or Hurricane Irma in the Caribbean, blasting sites with rain, flooding, and gale-force winds.

Cultural heritage assets around the world are at risk. They are often vulnerable due to their age, as well as previous interventions and restorations made without disaster risk or overall site stability in mind. Heritage sites reflect legacies, traditions, and identities. With all this, they carry a large cultural and emotional value of what could be lost – certainly beyond the traditional calculus of economic losses.

In many cases, it is not possible or advisable to conduct reconstruction on cultural heritage sites post-disaster. Therefore, the essence and soul of a cultural heritage site is at risk of being lost forever, making preparedness and preservation even more critical.

How can we protect these special places and traditions from the threat of natural hazards?

Better forecast, better preparedness – investing in improved weather services

Sun or rain? Most of us rely on the daily weather forecast to know what to wear or whether to bring an umbrella. However, for millions of people living in flood prone areas, timely and accurate forecasts, as well as early warning, can impact more than just clothing choices –they can help minimize flooding impacts.
 
Floods are the most frequent and damaging among natural hazards. Between 1980 and 2016, floods led to economic damages exceeding US$1.6 trillion, and more than 225,000 people losing their lives. Compounded by rapid urbanization and climate change, these losses will likely increase, especially in fast-growing countries.

Antananarivo: A city for whom?

Planning is a theme in cities as ancient as Rome, Cairo, and Athens to as modern as New York and Singapore. It is used as an instrument to manage collective living. Planning remains key in shaping the urban contract of how and to what end people are willing to inhabit the same space.
 
Madagascar is witnessing rapid urbanization. From an overall population of 24.8 million (2016), the country has close to 7 million urbanites, compared to 2.8 million in 1993. Cities generate about 3/4 of the national GDP, with the capital city, Antananarivo, contributing more than 50%.

Reviving Degraded Wetlands in India’s North Bihar

Kanwar Jheel is the largest in a series of 18 wetlands spread across the Ganges flood plains in India’s north Bihar. For generations, these wetlands have been the mainstay for this densely populated region, enabling families to farm the fertile soil and fish in nutrient-rich waters.

During the monsoon, when the River Burhi Gandak - a Ganges tributary - overflows its banks, the wetlands absorb the runoff, protecting this extremely flood-prone region. When the rains are over, the water shrinks to one tenth the size, exposing marshes and grasslands that create a mosaic of habitats for a wide variety of flora and fauna.

In winter, over 60 species of duck and waterfowl visit these wetlands on their annual migration routes along the Central Asian Flyway.

From Istanbul to Manila—different fault lines, similar challenges

Elif Ayhan's picture
 “It’s not the mountain we conquer, but ourselves.” This was the response given by Sir Edmond Hillary when asked how he and his companion Tenzing Norgay became the first to summit Mt Everest, when so many before had failed. He believed we could all overcome our biggest challenge simply by deciding to act.

Is it possible for the same sentiment to be applied by government leaders – leaders who have the privilege and responsibility to preside over some of the world’s largest and most dynamic cities, especially those that share a common challenge in terms of seismic risk? Metro Manila, the megacity of the Philippines, the seat of government, and the engine of the national economy, has been destroyed numerous times over the last 500 hundred years by earthquakes, and currently sits upon a fault that is overdue to move. Istanbul, with world-class cultural heritage sites treasured by all, also sits near major fault lines expected to move any day. Tokyo and Wellington, the heart of government, culture, and history, also share exposed locations close to major fault lines.

In Wellington, decades of work – including the current Get Ready week! – have aimed to prepare the city for the next “big one”; but compared to the burgeoning megacities of Manila, Tokyo, or Istanbul, it is a small hill to conquer. How do you prepare these megacities with population of up to 15 million people? How do you climb the mountain of needs to build resilience? According to Sir Hillary, the answer is simple, you need to take the decision to accomplish something extraordinary.

In September 2017, the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) through the Japan-World Bank Program for Mainstreaming Disaster Risk Management in Developing Countries supported a knowledge exchange between Turkey and the Philippines focused on the challenge of building seismic resilience in megacities with high urbanization. For the World Bank, it was clear from the start that seismic risk is a priority on the Urban Resilience Agenda, when Johannes Zutt was able to explain to the visiting delegation the technical details of how base isolation is used to protect critical hospitals in Istanbul. The delegation saw impressive progress made by Turkey and Istanbul, from revised institutional frameworks, strengthened preparedness and response capabilities, and retrofitted schools and hospitals to adapted municipal e-services that ensure that the construction of resilient new buildings are approved fast and with the right safety checks. While massive seismic risk still exists within Istanbul, visible and concrete actions are also underway to improve the safety of its citizens.

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.

Leaving no one behind – achieving disability-inclusive disaster risk management

Natural hazard events can occur in any country, at any time.  At present, India, Bangladesh, and Nepal are dealing with the aftermath of some of the worst monsoon flooding in years, which has left more than 1,200 people dead and millions homeless.  At the same time, North America and the Caribbean region are responding to some of the strongest hurricanes on record.

At such times of peril, individual and community resilience is at a premium, and we cannot afford to miss opportunities to bolster that resilience wherever possible. This is especially true with respect to certain groups – such as persons with disabilities – who have historically been disproportionately affected by natural hazards.

While some strides have been made in addressing the needs of persons with different disabilities in response and recovery efforts, fewer efforts are aimed at incorporating lessons into long-term disaster and climate risk management at a systemic and/or policy level.  

More needs to be done to create disability inclusion for all – a topic that was discussed during a Facebook Live chat on September 19.

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).
