Picture Trade: How to be a wiz at WITS trade data visualizations

Siddhesh Kaushik's picture

Ever needed to know exactly how much a country exports or imports of a product? How about which trade partners are most important to a country? Or how those relationships and patterns of trade have changed over time?
 
There is now an easy way to get this picture using the WITS Country Analysis Trade Data Visualization tool. Here's how it works. In the visualization below, select a country, a year, whether you want trade flow data for imports or exports, and whether you want to view the data by partner country or by product.

Below these options is a slider, which shows the number of partners/products in the data set. You can adjust this slider to focus on any range of numbers. Say, for example, you are interested in only the top 10 partners, then you can set the slider from 1-10 to view only the top 10-- or slide it in the other direction to see the smallest trade partners. Happy exploring, and post your comments if you find something interesting!

Tomorrow’s world: seven development megatrends challenging NGOs
The Guardian
As we move into 2015, many UK-based NGOs are wondering how to meet the challenges of a crucial year. What is the unique and distinct value that each organisation, and the UK sector as a whole, brings to international development, and how might this change in future? To help the sector get on the front foot we have identified seven “megatrends” and posed a few questions to highlight some of the key choices NGOs might need to make. At the end of next week we’ll be concluding a consultation with DfID on the future of the sector – all your thoughts are welcome.

Why emerging markets need smart internet policies
Gigaom
The Alliance for Affordable Internet (A4AI) has released its latest study into, well, the affordability of internet access. The study shows how big the challenge is on that front in emerging markets – for over two billion people there, fixed-line broadband costs on average 40 percent of their monthly income, and mobile broadband costs on average 10 percent of their monthly income. The United Nations’ “affordability target” for internet access is five percent of monthly income, so there’s clearly a ways to go in many developing countries. Almost 60 percent of global households are still unconnected and, unsurprisingly, those who can’t afford to get online tend to be poor, in rural communities and/or women.

Big Data needs better questions

Elizabeth Sabet's picture

The term "big data" is much in the news lately – alternatingly touted as the next silver bullet potentially containing answers to myriad questions on natural and human dynamics, and dismissed by others as hype.  We are only beginning to discover what value exists in the vast quantities of information we have today, and how we are now capable of generating, storing, and analyzing this information. But how can we begin to extract that value?  More importantly, how can we begin to apply it to improving the human condition by promoting development and reducing poverty?
 
That is precisely the question that motivated the World Bank Group and Second Muse to collaborate on the recently released report Big Data in Action for Development. Interviews with big data practitioners around the world and an extensive review of literature on the topic led us to some surprising answers.

“Smart mobility” for developing cities

In many developing cities, transport infrastructure – whether it be roads, metro systems or BRT - is not growing fast enough, and cannot keep up with the ever-increasing demand for urban mobility. Indeed, constructing urban transport infrastructure is both expensive and challenging. First, many cities do not yet have the capacity to mobilize the large amount of funds needed to finance infrastructure projects. Second, planning and implementing urban transport infrastructure projects is tough, especially in dense urban areas where land acquisition and resettlement issues can be extremely complex. As a result, delays in project implementation are the norm in many places.

Therefore, solving urgent urban transport problems in these cities requires us to think outside the box. Fortunately, the rapid development of ICT-enabled approaches provides a great opportunity to optimize and enhance the efficiency of existing and new urban transport systems, at a cost much lower than building new infrastructure from the ground up.

Big Data comes to transport planning: how your mobile phone helps plan that rail line

Shomik Mehndiratta's picture
Understanding peoples’ travel activity patterns, and ideally understanding the motivations and choices underlying them, are at the heart of what transport planners do. 
 
An understanding of trip origins and destinations – and how trip-makers select routes, modes and destinations – are required to plan extensions or changes to a road or public transport network; to assess the viability of a new investment; and to assess how well the existing transport system is serving the population and businesses in a specific area.

​Indeed, in our roles as transport specialists in the World Bank, much of our job is about supporting clients’ ability to develop this understanding and to use the results to evaluate and appraise investments.
 
At the core of this process is an Origin-Destination (OD) survey: essentially a matrix of trips between different zones of a region (referred to as an OD matrix).  Traditionally, getting this information in the context of an urban area has been a difficult, expensive and time-consuming process. We are often talking about millions of dollars for trip activity surveys of thousands of households, complemented by extensive analysis of socio-economic data. We also count data at strategic points on major roadways and transit routes to calibrate the results. 
 
This process can take up to a year, and many stages need very specific technical skills and a lot of quality control.  Survey design, sample design, training the surveyors, ensuring they are accurate (not making up data, not entering data erroneously), and subsequent stages of analysis all require significant technical capacity to implement, as well as an almost equal level of technical skill to supervise the work. 
 
All of us who do this have horror stories from processes on which we have worked. The result is that the basic information needed to test alternatives and make decisions about transport investments is collected too rarely – at best no more than once every decade – and even the results of existing surveys have suspect deficiencies.

Facebook Reaches a Landmark 100-Million Users in Africa Through Mobile
AllAfrica
Thanks to mobile connectivity, half of Africa's 200-million internet users were accessing Facebook on a monthly basis in June 2014, indicating that the social media giant's efforts at penetrating emerging market are paying off. There's explosive growth and incredible momentum across Africa. "We now have 100-million people coming to Facebook every month across the African continent with more than 80% using mobile devices," says Nicola Mendelsohn, Facebook vice president for Europe, Middle East and Africa.

UNICEF's Hidden in Plain Sight report details child homicides, domestic violence in 190 countries
Radio Australia
One in five homicide victims worldwide are children, a report by UN children's agency UNICEF has revealed. The Hidden in Plain Sight report analyses data from 190 countries and lists alarming statistics on child homicides, domestic violence and rape. The report found violence against children was most common in the home and with caregivers.  UNICEF spokesman for Eastern and Southern Africa, James Elder, said the report may not even capture the full extent of the problem.   "Violence is a very difficult thing often to detect, it goes grossly unreported, so one of the terrifying things from this report is knowing that in fact the numbers would be lower than the reality," he said.

Media (R)evolutions: Global Mobile Data 2014 - Traffic Growth and Forecast

Roxanne Bauer's picture

New developments and curiosities from a changing global media landscape: People, Spaces, Deliberation brings trends and events to your attention that illustrate that tomorrow's media environment will look very different from today's, and will have little resemblance to yesterday's.

Every day, people create 2.5 quintillion bytes of data- this astonishing rate means that 90% of the data in the world today was created in just the last two years! 

Sources of data include mobile phones, tablets, the Internet of Things, and social media. Mobile technologies, in particular, have contributed to the growth of mobile data as new apps are created and used every day to to send text, make mobile payments, watch multimedia, or shop to name a few.  These activities all leave a digital footprint-- big data that can be analyzed. 

The graphic below illustrates recent global mobile data traffic growth by region and provides a forecast for the coming years:

Are You the Perpetrator of Your Own Loss of Privacy?

Roxanne Bauer's picture

Exploring ideas, innovations and fresh approaches to our world is at the heart of the public sphere. People, Spaces, Deliberation brings you significant voices from academia and the practice of development through a series of interviews.

Do conventional notions of privacy still exist? Are we trading privacy for convenience?  If privacy is a thing of the past, is this a bad thing?

According to Professor Silvio Waisbord, an expert on global media, development, and social change, the answer is mixed.  People trade the downsides of losing privacy in exchange for convenience, simplification, and other social factors. 

The interesting question for him is, "What do people typically do when they are confronted with the fact that you are one of the main perpetrators of your loss of privacy. What do you do about that? Are you willing to make changes about that?"

Can Big Data Stop Wars Before They Happen?
Foreign Policy
It has been almost two decades exactly since conflict prevention shot to the top of the peace-building agenda, as large-scale killings shifted from interstate wars to intrastate and intergroup conflicts. What could we have done to anticipate and prevent the 100 days of genocidal killing in Rwanda that began in April 1994 or the massacre of thousands of Bosnian Muslims at Srebrenica just over a year later? The international community recognized that conflict prevention could no longer be limited to diplomatic and military initiatives, but that it also requires earlier intervention to address the causes of violence between nonstate actors, including tribal, religious, economic, and resource-based tensions. For years, even as it was pursued as doggedly as personnel and funding allowed, early intervention remained elusive, a kind of Holy Grail for peace-builders. This might finally be changing. The rise of data on social dynamics and what people think and feel -- obtained through social media, SMS questionnaires, increasingly comprehensive satellite information, news-scraping apps, and more -- has given the peace-building field hope of harnessing a new vision of the world.

The economist who revealed how media bias works
Quartz
It’s heady company. When he won the John Bates Clark Medal earlier this month, University of Chicago economics professor Matthew Gentzkow suddenly found himself among legends such as Paul Samuelson and Milton Friedman. Both are past recipients of the award, which the American Economic Association bestows on the American economist under the age of 40 who “who is judged to have made the most significant contribution to economic thought and knowledge.” Plenty of past winners have worked in familiar areas, such as wage dynamics or health economics. Gentzkow’s work is less orthodox: an interesting mix of the history and micro-economics of the media world.
