Blog post of the month: Mapping Nepal after the earthquake

Roxanne Bauer's picture

Each month People, Spaces, Deliberation shares the blog post that generated the most interest and discussion. In April 2015, the featured blog post is "Media (R)evolutions: Mapping Nepal after the earthquake".

On April 25, 2015, a 7.8 magnitude earthquake struck Nepal, rattling the country and affecting 8 million people across 39 districts, with a quarter of those in the worst affected areas. More than 5,000 people have been confirmed dead so far.

Relief agencies are now in the country, providing supplies, administering medical treatment, and searching for survivors. In an effort to support disaster responders, teams of volunteers around the world are scouring through thousands of high-resolution satellite images to provide those on the ground with as much information as possible so they can do their jobs most effectively.

Many of these so-called “crisis mappers” are untrained volunteers who compare before and after images of the affected areas to tag buildings that have collapsed, roads that are blocked, and areas of heavy debris. This provides crucial information to disaster response teams on the ground.

The people of Nepal have also been utilizing other tools to locate missing family and friends, identify themselves as safe, and find rescue and gathering places where help can be obtained.

Modeled 2012 population in Guatemala at a spatial resolution of 100 m2
People are at the center of all development work: whether we act to prevent and address disasters, protect vulnerable communities, finance projects in infrastructure, education or health, our ultimate goal is always to serve people. Being able to identify, understand and locate beneficiaries as accurately as possible is an essential first step in that process, and the only way to make sure we provide services to those who need it most with maximum impact.

Inside the World Bank, the number of people passionate about using spatial data for development speaks to the relevance of spatial datasets in supporting critical decision making. In an effort to use spatial data more strategically, we recently conducted an informal poll among several Bank units and some partner institutions to find out what types of spatial data are most relevant to development professionals.

This survey found that the spatial distribution of the population was a key data layer needed by Bank staff. The results of the survey showed that that while national level data are useful, subnational detail on administrative boundaries, trade & transport infrastructure, population distribution and socio-economic data down to the city level are just as critical to the majority of respondents.

#4 from 2014: How User-Generated Crisis Maps Save Lives in Disasters

YouTube, Wikipedia, Facebook, LinkedIn, Instagram, Twitter, blogs… This list could easily go on and on for paragraphs. Today, we are so immersed in social media that we can hardly go a day without reading or watching user-generated online content. Videos like “Charlie Bit My Finger” make us laugh. Free lessons on Khan Academy, which were originally started by a hedge fund analyst at home, help us learn.

But user-generated online content is not all about entertainment and free classes. Crisis maps on crowd-sourcing platforms like OpenStreetMap and Ushahidi have demonstrated a less expected yet significant capacity of user-led content creation online:  it saves lives in disasters.

Accessing the Inaccessible

Adam Smith International's picture

Despite insecurity, development must continue. But how can donors be confident their money is well spent if locations are inaccessible?
 
Last month, insurgents killed more than 60 people in north-east Kenya. This is only the latest in a wave of violent incidents heightening insecurity along the remote Somali-Kenyan border.
 
The north-east is one of the poorest regions in Kenya. Weak infrastructure and limited public services are exacerbated by banditry and insurgency. The national primary school enrolment rate is over 90%, but in the north-east it is below 40%.
 
It is clear that despite insecurity, development and investment must continue. But how can donors be confident their money is well spent if locations are inaccessible to most implementing partners? If donors can’t see results, they are unlikely to reinvest.

Mapping Digital Media: Global Findings
Open Society Foundation
Is a world where there are almost as many mobile phones as people, more than half the globe can access digital TV signals, and almost 3 billion people are online a better place for journalism?  The Global Findings of the Mapping Digital Media project assess these and other forces affecting digital media and independent journalism worldwide. Researched and written by a team of local experts, the 56 country reports, from which these Global Findings are drawn, examine the communication and media environments in 15 of the world’s 20 most populous countries, covering more than 4.5 billion of the world’s population, and in 16 of the world’s 20 largest economies.
 
Global Inequality: What to Address?
Huffington Post
We normally would not expect a seven-hundred-page scholarly tomb full of numbers and figures written by an academic to become an international bestseller. The success of Capital in the Twenty-First Century by Thomas Piketty indicates that the public discontent caused by the rising inequality in the modern capitalist societies may have reached a boiling point. The debate surrounding Capital has been intensely polarizing, inciting passionate responses from the intelligentsia of both the Left and the Right.

The Things We Do: Shame is a Powerful Thing

Roxanne Bauer's picture

Billions of dollars are spent each year on sanitation, healthcare, and good governance, but the results vary quite a bit from place to place.  What separates successful programs from the unsuccessful?
 
Those that achieve their goals try to change behavior alongside introducing new methods or making investments. One way to change behavior is to use shame— an overwhelmingly negative emotion —to emotionally link individuals to the communities in which they live.
 
Shame and Sanitation

Shame was, in fact, a central ingredient to a program in Bangladesh that reduced the percentage of Bangladeshis defecating out in the open from 19% in 2000 to only 3% in 2012.

The program utilized the Community-Led Total Sanitation (CLTS) method, which “focuses on instigating a change in sanitation behaviour rather than constructing sanitation infrastructure.” Changes in sanitation behaviors are accomplished through a process of deliberation and discussion within communities to build consensus on the need to end open defecation and clarify the hazards that open defecation poses.

Corruption 'impoverishes and kills millions'
BBC
An estimated $1tn (£600bn) a year is being taken out of poor countries and millions of lives are lost because of corruption, according to campaigners. A report by the anti-poverty organisation One says much of the progress made over the past two decades in tackling extreme poverty has been put at risk by corruption and crime. Corrupt activities include the use of phantom firms and money laundering. The report blames corruption for 3.6 million deaths every year. If action were taken to end secrecy that allows corruption to thrive - and if the recovered revenues were invested in health - the group calculates that many deaths could be prevented in low-income countries.
 
The Best and Worst Places to Build More Roads
Smithsonian
Roads are taking over the planet. By the middle of this century, so many new roadways are expected to appear that their combined length would circle Earth more than 600 times. To build critical connections while preserving biodiversity, we need a global road map, scientists argue today in the journal Nature. And as a first step, the international team has identified areas where new roads would be most useful and those where such development would likely be in conflict with nature.

Role reversal as African technology expands in Europe
Phys Org
Africans have long used technology developed abroad, but now a Kenyan cash transfer network which bypasses banks is being adopted in Europe. The M-Pesa mobile money transfer system which allows clients to send cash with their telephones has transformed how business is done in east Africa, and is now spreading to Romania. "From east Africa to eastern Europe, that's quite phenomenal when you think about it," Michael Joseph, who heads Vodafone's Mobile Money business, told AFP in the Kenyan capital Nairobi. "I think that this is something the rest of the world can look at, to say that there are ideas that can emanate out of the developing world, and take it to the developed world."

New Report for Latin America and the Caribbean Freedom of expression and media development: Where are we heading?
UNESCO
Over the past six years, Latin America and the Caribbean continued to comply with the basic conditions that guarantee freedom of expression and media freedom, although the situation has not been homogeneous throughout the 33 countries in the region. Even where strong legislation has existed, implementation has remained a challenge. Several Latin American countries have approved new media laws that have been perceived by some as an opportunity to make the media landscape more pluralistic and less concentrated, and by others as an opportunity for the governments to act against media outlets that have been critical of their administrations. The same debate has applied to steps to revise out-of-date media laws, including those left over from military dictatorships.
 

Putting poverty on the map

Kathleen Beegle's picture

The expansion of household surveys in Africa can now show us the number of poor people in most countries in the region. This data is a powerful tool for understanding the challenges of poverty reduction. Due to the costs and complexity of these surveys, the data usually does not show us estimates of poverty at “local” levels. That is, they provide limited sub-national poverty estimates.
For example, maybe we can measure district or regional poverty in Malawi and Tanzania from the surveys, but what is more challenging is estimating poverty across areas within the districts or regions (known as “traditional authorities” in Malawi and “wards” in Tanzania).
 
To address this shortfall, several years ago a research team from the World Bank developed a technique for combining household surveys with population census data, and poverty maps were born.  Poverty maps can be used to help governments and development partners not only monitor progress, but also plan how resources are allocated. These maps depend on having access to census data that is somewhat close in time to the household survey data.  But what if there is no recent census (they are usually done every 10 years) or the census data cannot be obtained? (I will resist naming and shaming any specific country): we are left with no map.  Can we fill in the knowledge gaps in our maps?
