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).

Bangladesh: Building resilience in the eye of the storm (Part 3/3)

This is the third of a three-part series, Resilience in the of the Eye of the Storm, on how Bangladesh has become a leader in coastal resilience.
 
Over the years, Bangladesh has taken major strides to reduce the vulnerability of its people to disasters and climate change. And today, the country is at the forefront in managing disaster risks and building coastal resilience.
 
Let’s compare the impact of the Bhola Cyclone of 1970 to the far stronger Cyclone Sidr in 2007. The 1970 cyclone was then the deadliest in Bangladesh’s history, and one of the 10 deadliest natural disasters on record. Official documents indicate that over 300,000 lives were lost, and many believe the actual numbers could be far higher. 
 
By contrast, Sidr was the strongest cyclone to ever make landfall in Bangladesh. This time, fewer than 3,500 people lost their lives. While tragic, this represents about 1% of the lives lost in 1970 or 3% of the nearly 140,000 lost lives in the 1991 cyclone.
 
The cyclones of 1970 and 1991 were unprecedented in scale. Yet, they steered the country into action.

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.

This is the second of a three-part series, "Resilience in the of the Eye of the Storm," on how Bangladesh has become a leader in coastal resilience.

 
With a population of 160 million, Bangladesh is situated at the epicenter of some of the deadliest cyclones the world has ever experienced. Catastrophic events are the norm rather than the exception. A severe tropical cyclone can strike every 3 years and 25% of the land floods annually.
 
The network of the mighty Ganges-Brahmaputra-Meghna rivers makes its meandering journey through the delta into the Bay of Bengal forming the coast of Bangladesh.
 
The jagged coastline of Bangladesh spans hundreds of miles and is subject to multiple challenges: 62% of the coastal land has an elevation of up to 3 meters and 83% is up to 5 meters above sea level. These low-lying areas are highly vulnerable to natural hazards.
 
Earlier this year, I got a chance to see first-hand the challenges that this demanding landscape had brought onto the communities of a remote coastal village. What struck me most when speaking to members of this coastal community was their courage and resilience. Aware that a calamity can hit anytime, they struggle to protect their livelihoods affected by saltwater intrusion, and their own lives which are increasingly at risk due to rising sea levels, and exposure to more frequent and devastating storms and cyclones.
 
By 2050, the coastal population is projected to grow to 61 million people, whose livelihoods will increasingly be at risk due to the impact of climate change.
 
Triggered by climate change, seawater inundation could become a major problem for traditional agriculture. According to the Intergovernmental Panel on Climate Change Fifth Assessment Report (2014), climate-related declines in food productivity will impact livelihoods and exports and increase poverty. In Bangladesh, it is estimated that these factors would cause a net increase in poverty of 15% by 2030.
 
To mitigate against such risks, the government has been investing in strengthening the resilience of the coastal zone. Over the years, Bangladesh has become an example of how protective coastal infrastructure, together with social mobilization and community-based early warning systems, is helping to build resilience.

The road to resilience: sharing technical knowledge on transport across borders

For many countries, damages and losses related to transport are a significant proportion of the economic impacts of disasters, often more than destruction to housing and agricult+ure in value terms. For example, a fiscal disaster risk assessment in Sri Lanka highlighted that over 1/3 of all damages and losses over the past 15 years were to the transport network. In addition, climate change increases the damages and losses.
 
In the Kyrgyz Republic, where 96% of all cargo travels by road, any disaster-related disruptions to the road network would have severe repercussions on the economy. The Minister of Transport and Roads, Mr. Zhamshitbek Kalilov, is charged with protecting these systems from all kinds of natural hazards, from avalanches to floods.
 
Working to support country officials, like Mr. Kalilov, is why the World Bank Resilient Transport Community of Practice (CoP) and the Disaster Risk Management Hub of the Global Facility for Disaster Reduction and Recovery (GFDRR) organized the Technical Knowledge Exchange on Resilient Transport on May 8-12.

Held in Tokyo, the week-long exchange brought together World Bank clients and teams from 16 countries across all regions to share concepts and practices on resilient transport, including systems planning, engineering and design, asset management, and contingency programming. The exchange drew upon the experience of several countries and international experts who showcased innovative approaches and practical advice on how to address risk at every phase of the infrastructure life-cycle.

This blog is the first of  a series on how Bangladesh has become a leader in coastal resilience.
 
While flying along the coast of Bangladesh earlier this year, I saw from the sky a vast, serene delta landscape, crisscrossed by innumerable rivers and contoured paddy fields.
 
Nonetheless, I was aware that this apparent quietude might well be the calm before a storm.
 
Indeed. the magnitude of threats faced by Bangladesh is unprecedented in terms of risk, exposure and vulnerability. And with a population of 160 million, the country is one of the world’s most disaster prone and vulnerable to tropical cyclones, storm surges, floods, a changing climate and even earthquakes.
 
However, the story of Bangladesh is one of resilience.
 
After the deadly cyclones of 1970 and 1991, which together resulted in the loss of at least half a million lives, the government of Bangladesh instituted disaster risk reduction policies and invested in infrastructure and community-based early warning systems to reduce risks from coastal hazards.
 
Over the years, these investments in cyclone preparedness and flood management helped save lives, reduce economic losses, and protect developmental gains. As a result, the government’s actions are globally cited as being proactive in investing in disaster risk management.
 
The World Bank has been a longstanding partner of the government in investing for resilience.

How can a country vulnerable to natural disasters mitigate the effects of climate change? In Bangladesh, resilient communities have shown that by using local solutions it is possible to combat different types of climate change impacting different parts of the country.
 
Every year, flash floods and drought affect the north and north-west regions. Drinking water becomes scarce, land becomes barren and people struggle to find shelter for themselves and their livestock. In the coastal districts, excessive saline makes it impossible to farm and fish.
 
The Community Climate Change Project (CCCP) has awarded grants to around 41 NGOs to address salinity, flood and drought-prone areas. With the help from local NGOs, communities innovated simple solutions to cope up with changing climate and earn a better living benefiting at least 40,000 people in the most vulnerable districts.
 
Raising the plinths of their homes in clusters has helped more than 15,000 families escape floods, and they continued to earn their livelihoods by planting vegetables and rearing goats on raised ground. Vermicomposting has also helped to increase crop yields. In the saline affected areas, many farmers have started to cultivate salinity tolerant crabs with women raising their income level by earning an additional BDT 1500 a month from saline tolerant mud crab culture in high saline areas.
 
Watch how communities use these three solutions to tackle climate change impacts.

Building a more resilient Afghanistan

Helping Afghanistan Become More Resilient to Natural Disasters


This blog is part of a series highlighting the work of the Afghanistan Disaster Risk Management and Resilience Program

During the almost 4 years I spent in the World Bank office in Kabul, I experienced frequent earthquake tremors and saw the results of the significant reduction in winter snow, which severely impacts the water available for agriculture during spring and summer.
 
While limited in scope, my first-hand experience with natural disasters adds to the long list of recurring hazards afflicting Afghanistan. This list is unfortunately long and its impact destructive.
 
Flooding, historically the most frequent natural hazard, has caused an average $54 million in annual damages. Earthquakes have produced the most fatalities with 12,000 people killed since 1980, and droughts have affected at least 6.5 million people since 2000.

Climate change will only increase these risks and hazards may become more frequent and natural resources more scarce. Compounded with high levels of poverty and inadequate infrastructure, the Afghan population will likely become more vulnerable to disasters.

Risk information is critical to inform development planning, public policy and investments and over time strengthen the resilience of new and existing infrastructure to help save lives and livelihoods in Afghanistan.

Are roads and highways the Achilles Heel of Brazil?

Over the past three years and a half, our team has been working on a transport project with the state of São Paulo in Brazil. The project involves a lot of traveling, including frequent commutes between the World Bank office in Brasilia and the State Department of Transport in São Paulo (DER-SP)—a journey that is estimated to take 2 hours and 40 minutes. This includes the time to drive from the World Bank office to Brasilia Airport, flight time, and commuting from São Paulo’s Congonhas Airport to the State Department of Transport.
 
Let’s say that, on a typical Wednesday, the team needs to attend a meeting in São Paulo. To ensure we can make it on time, we plan our day carefully, book our flights and define the right time to leave the office in Brasilia. With a plan in place, we leave the office at 10:00 am and head to Brasilia Airport. The first leg of the trip takes 35 minutes and we manage to arrive early for our 11:00 am flight, which, unfortunately, is delayed by 20 minutes. We land in São Paulo, quickly get out of the terminal, and manage to hop on a taxi at 1:20pm… not bad! We are now on the last leg of our journey, a mere 14-kilometer drive between Congonhas Airport and the meeting place, which is supposed to take only 20 minutes. However, there is a short thunderstorm that floods the city and closes off key streets. This single event leads to complete traffic chaos along the way, and our planned 20-minute transfer from the airport turns into a 1-hour-and-15-minute ordeal. These traffic disruptions have a serious impact on our meeting as well, as some Department of Transport staff cannot join and some items of the agenda cannot be discussed.
 
This incident may seem anecdotal, but it is a good illustration of our extreme dependency on transport systems and the weaknesses associated with it. Because transport is so critical to our social and economic lives, it is extremely important to understand, anticipate, and minimize the different types of risks that may impact transport systems.
