“At 14:28:04 on May 12, 2008, an 8.0 earthquake struck suddenly, shaking the earth, with mountains and rivers shifted, devastated, and parted forever….” This was how China’s official report read, when describing the catastrophic consequences of the Sichuan earthquake, which left 5,335 students dead or missing.
 
Just two years ago, in Nepal, on April 25, 2015, due to a Mw 7.8 earthquake, 6,700 school buildings collapsed or were affected beyond repair. Fortunately, it occurred on Saturday—a holiday in Nepal—otherwise the human toll could have been as high as that of the Sichuan disaster, or even worse. Similarly, in other parts of the world—Pakistan, Bangladesh, Philippines, Haiti, Ecuador, and most recently Mexico—schools suffered from the impact of natural hazards. 
 
Why have schools collapsed?

Ideas Box: the library that promotes literacy and builds disaster resilience—a Q&A

Barbara Minguez Garcia's picture


Over the last two weeks, we’ve witnessed three hurricanes in the Caribbean and Gulf of Mexico as well as a magnitude 8.1 earthquake in Mexico, killing people and destroying homes. They serve as a reminder that natural hazards pose a greater threat to our lives and livelihoods than we may think.

Dealing with rising disaster risks requires greater efforts with smarter approaches—ones that can help vulnerable people and communities better prepare for, and recover from, disasters. Libraries Without Borders (BSF), an international organization that expands access to information, education, and cultural resources to vulnerable people around the world, knows that very well.

In 2010, BSF was building libraries in Haiti when the well-known earthquake struck. At the time, local partners asked BSF to help them create information and cultural access points in refugee camps. This experience led to the development of the “Ideas Box," an innovative tool that provides vulnerable communities in disaster-prone areas with access to information, education, and cultural resources.

Last week, on the International Literacy Day, I talked to BSF’s Director of Communications and Advocacy, Katherine Trujillo, about the Ideas Box, as well as how their innovative ideas and actions have helped promote literacy and build resilience in disaster-hit communities.

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.”

 

Disasters, funds, and policy: Creatively meeting urgent needs and long-term policy goals

When it comes to responding to disasters, time is of the essence. Help needs to come immediately to save lives; recovery and reconstruction have to start swiftly to lessen the impact.

However, while money is critical to this response, it’s not just about funding. Indeed, funds need to match the event scale, target the right areas and sectors, and smoothly flow to communities in need. But in order for that to happen, sound public policy on risk and frameworks have to be in place.  

To address both urgent financial needs while pursing strategic disaster risk management policy goals, countries have been using the World Bank’s development policy loan with a catastrophe deferred drawdown option or, more widely known as the Cat DDO.  

Three countries show why culture matters for post-conflict and post-disaster reconstruction and recovery

Imagine a city destroyed by a natural disaster, killing people and wiping away infrastructure. For instance, an earthquake devastated Port-au-Prince, Haiti in 2010, killing over 200,000 people and displacing around 895,000.

Even worse, imagine a city demolished by a manmade disaster: conflict. Recent examples include Aleppo, Syria and Kabul, Afghanistan. Here conflict goes far beyond violence to include erasing a place’s culture, heritage, landmarks, and its traditions.

Now, imagine the enormous undertaking required to rebuild these places and the many stakeholders that need to be brought together. It would take an integrated, holistic approach to restore torn heritage, infrastructure, and service delivery systems after they have been wiped out by a natural or manmade disaster. Culture needs to underpin such a rebuilding approach.

Mapping and measuring urban places: Are we there yet? (Part 1/2)

This satellite image shows Sao Paolo's estimated “urban areas” based on a WorldPop gridded population layer. Areas in yellow are areas with at least 300 people per km2 and a known settlement size of 5,000 people. Red areas represent a population density threshold of at least 1,500 people per km2 and a known settlement size of 50,000 people.
There remains a surprising amount of disagreement over precisely what “urban” means despite the ubiquity of the term in our work. Are urban areas defined by a certain amount of artificial land cover such as permanent buildings and roads? Or are they more accurately described as spatially concentrated populations? The answer often depends on what country you are in, as their administrative definitions of urban areas can vary widely across and between these two dimensions.
 
Without a globally consistent measure of urban areas, it can be difficult to track changes in built-up areas (land surface coverage comprised of buildings and roads) and population growth across time and space. This impacts how policymakers may understand and prioritize the challenges cities face and what investments or reforms may be needed. In a new paper, “Bright Lights, Big Cities: a Review of Research and Findings on Global Urban Expansion,” I provide a brief introduction to some of the current approaches for measuring urban expansion and review the comparative findings of some recent studies.
The UN’s World Urbanization Prospects (WUP), perhaps the most comprehensive and widely cited measure of urbanization across the world, draws from a compilation of country-level population totals based on administrative definitions. A key weakness with this set is that since each country defines “urban” differently, it is difficult to accurately compare one country’s urbanization to another, as well as to estimate the urban population of a group of countries or the world itself. Recent work has provided more sophisticated ways to measure urban growth and expansion using both satellite map data and careful application of population data.

Three misconceptions in the way of better housing policies

​While the need for housing is widespread, individually people have different needs—depending on whether they are single, married, senior citizens, families with children, or members with disabilities. Despite the best of intentions of policymakers, "a roof overhead" remains an elusive goal for a large majority of the world’s people. Most households cannot afford even the cheapest house that fits their needs and qualifies as “decent,” and no government alone can close this gap with subsidies. Nor are we on track to build the 300 million new houses needed to close the housing gap by 2030.

What’s missing? At least three misconceptions stand in the way of better housing policies: 
 

Let’s build the infrastructure that no hurricane can erase

Hati after Hurrican Matthew

The news from Haiti about the aftermath of Hurricane Matthew is a familiar story: more chaos, rubble, and loss of life from another natural disaster. Though recent improvements to Haiti’s infrastructure at the local level kept the death toll at 534—3,000 died in the 2004 hurricane; more than 200,000 in the 2010 earthquake—the number is still way too high.
 
Worldwide, natural disasters claimed 1.3 million lives between 1992 and 2012, with earthquakes accounting for 60%of disaster deaths in low- and middle-income countries, where the preponderance of sub-standard housing increases the risks. Today, 1.2 billion people live in substandard housing. By 2030, this figure will almost triple.
 
The good news is that most of those deaths and property losses can be prevented. In 2003, for example, within three days of each other, earthquakes of similar magnitude struck Paso Robles, California and Bam, Iran. The death toll in Bam was 40,000—nearly half the city’s population. Two people died in Paso Robles.
 
Even when destruction does take place, proper planning and measures can ensure a speedy recovery.

Retrofitting: A housing policy that saves lives

When a hurricane, earthquake or other natural disaster strikes a poor country, families too often suffer a double tragedy: the loss of loved ones and their most valuable (and sometimes only) asset, their home. In the aftermath of the 7.0 magnitude earthquake in Haiti in 2010, which killed more than 260,000 people, 70% of asset losses were related to housing. Ecuador faces billions of dollars in reconstruction costs from last April’s 7.8 earthquake, which killed 900 and injured almost 28,000. If Peru were hit by an 8.0-degree earthquake, an estimated 80% of potential economic losses would involve housing.
 
And while nature’s fury does not distinguish between urban and rural areas, a large majority of disaster losses are concentrated in cities, where they disproportionately affect the poor. This creates a great challenge for low and middle-income countries.  In Latin America and the Caribbean, 200 million people—1/3 of the population—live in informal settlements, where most dwellings don’t comply with construction codes and home insurance is non-existent. Perhaps unsurprisingly, LAC’s informal districts also account for the majority of disaster-related deaths in the region.
