Innovator Stories and Profiles | 2012 to 2014

Southern Innovator was initially launched in 2011 with the goal of - hopefully - inspiring others (just as we had been so inspired by the innovators we contacted and met). The magazine seeks to profile stories, trends, ideas, innovations and innovators overlooked by other media. The magazine grew from the monthly e-newsletter Development Challenges, South-South Solutions published by the United Nations Office for South-South Cooperation (UNOSSC) since 2006.

Southern Innovator visited South Korea's Songdo Smart City in 2012.

Big Data Can Transform the Global South’s Growing Cities

The coming years will see a major new force dominating development: Big Data. The term refers to the vast quantities of digital data being generated as a result of the proliferation of mobile phones, the Internet and social media across the global South – a so-called ‘data deluge’ (UN Global Pulse). It is an historically unprecedented surge in data, much of it coming from some of the poorest places on the planet and being gathered in real time.

Big Data will have a profound impact on how the cities of the future develop, and will re-shape the way the challenges and problems of human development are handled.

Estimates by Cisco (cisco.com) foresee 10 billion mobile Internet-enabled devices around the world by 2016. With the world population topping 7.3 billion by then, that will work out to 1.4 devices per person.

Some estimates say 90 per cent of the digital data ever generated in the world has been produced in the past two years. It is also estimated that available digital data will increase by 40 per cent every year (UN Global Pulse). This digital transformation is being accompanied by another trend: the largest migration in human history from rural to semi-urban and urban areas.

This presents an unprecedented opportunity to make this rapid urbanization and social change smarter and more responsive to human needs, and to avoid the failures of the past, from over-crowding to crime, disease, pollution, unemployment and poverty. Some believe data collection can radically alter development by flagging up problems quickly, giving cities the chance to respond and correct negative trends before they get out of control. In short, to build in resilience by way of digital technology.

The latest region to see rapid industrialization and urbanization has been Asia – in particular China, a country that since the 1980s has simultaneously lifted the largest number of people in world history out of poverty and undertaken the biggest migration ever from rural to urban areas.

And now Africa is beginning to follow in Asia’s wake.

Unlike previous waves of industrialization and urbanization, Africa’s transformation is occurring in the age of the mobile phone, the Internet, personal computers and miniature electronic devices capable of more computing power than the computers used during the Apollo space programme (http://www.nasa.gov/audience/foreducators/diypodcast/rocket-evolution-index-diy.html). This changes the game significantly.

This 21st-century approach to urban growth is at its most sophisticated, and utopian, in so-called “smart cities.” These are built-from-scratch cities that use the “Internet of Things”, where everything, from lamp posts to garbage bins to roads are embedded with microchips and radio frequency transmitters (RFID chips) (http://en.wikipedia.org/wiki/Radio-frequency_identification) to communicate data in real time. By analyzing this data, cities can be responsive to human needs and mitigate problems – improving waste collection and traffic management, reducing crime and pollution. Services can be customized to residents’ needs and liberate them to spend more time on things that matter such as their own health, family, work and hobbies. Examples of these cities include Tianjin Eco-city (tianjinecocity.gov.sg) in China, Masdar (masdar.ae) in Abu Dhabi in the United Arab Emirates and Songdo International Business District (songdo.com) in the Republic of Korea.

These experimental smart cities are springing up in the East, and it will be the East – as well as Africa – that will see most of the action going forward. As the global management consulting firm McKinsey noted in its report Urban World: Mapping the Economic Power of Cities: “Over the next 15 years, the center of gravity of the urban world will move south and, even more decisively, east.”

Cities in the global South will be generating the new prosperity of the 21st century. And it is widely accepted that people living in cities have the potential to become very efficient economically while rapidly driving prosperity higher.

The McKinsey report says that “by 2025, developing-region cities of the City 600 (a list gathered by McKinsey) will be home to an estimated 235 million middle-class households earning more than (US) $20,000 a year at purchasing power parity (PPP).

“Emerging-market mega-and middleweight cities together – 423 of them are included in the City 600 – are likely to contribute more than 45 percent of global growth from 2007 to 2025 (http://www.mckinsey.com/insights/urbanization/urban_world).”

The world’s future prosperity is going to be found in the urban, the digitally connected, and the middle class.

Tracking all this digital change is the UN Global Pulse. UN Global Pulse (unglobalpulse.org) was started by Secretary-General Ban Ki-moon in 2009 with a mandate to study these changes and build expertise in applying Big Data to global development. UN Global Pulse functions as a network of innovation labs where research on Big Data for development is conceived and coordinated. It partners with experts from UN agencies, governments, academia, and the private sector to research, develop, and mainstream approaches for applying real-time digital data to 21st-century development challenges.

Unlike major technological trends of the past, this one is not restricted to the industrialized, developed world. Through the spread of mobile phone technology, billions of people are now using a device that constantly collects digital data, even in the poorest places on earth.

From an international development perspective, Big Data has five characteristics, according to UN Global Pulse: it is digitally generated, passively produced by people interacting with digital services, automatically collected, can be geographically or temporally traced and can be continuously analyzed in real time.

Sources of Big Data include chatter from social networks, web server logs, traffic flow sensors, satellite imagery, telemetry from vehicles and financial market data.

The key to using Big Data is combining datasets and then contrasting them in lots of different ways and doing it very quickly. The purpose?  Better decision-making, based on an understanding of what is really happening on the ground.

This data exceeds the capability of existing database software. It is either too much, or comes in too quickly, or can’t be handled using current software technology. Tackling this problem is creating a whole new wave of opportunities for those working in information technology.

As technology and processing power continue to improve, the cost of wrestling with this data and putting it to use is coming down.

The data can be analyzed for patterns and hidden information that before would have been too difficult to gather. This approach has been used by big companies such as WalMart (walmart.com), but it has cost them a large amount of money and time.

Pioneers in Big Data include search engine Google, email and search provider Yahoo, online shopping service Amazon and social media service Facebook. Many supermarkets use Big Data to analyze the way customers behave when they are shopping, combining it with their social and geographical data.

But new developments in hardware, cloud architecture, and open-source software mean Big Data processing is more accessible, including for small start-ups, who can just rent the capacity required on a cloud-based service (http://en.wikipedia.org/wiki/Cloud_computing).

In the past, governments and planners had a ready excuse as to why they could not keep on top of ballooning urban populations and the chaos they brought. They could just throw up their hands and say “We do not know who these people are or what to do about them!”

This excuse does not work in the age of the mobile phone. It is now relatively easy to deploy the power of the networked computing inside mobile phones to map urban slums and identify the needs of the people there. Parse that data, and you have an accurate account of what is happening in the slum – all in real-time.

Making sense of all this information is creating its own new industries as innovators, entrepreneurs and companies step forward to chart this brave new world.

Historically, significant improvements in human development have occurred only after large-scale gathering of data and information on the actual living conditions of the population. For example, prototypes of today’s infographics (http://en.wikipedia.org/wiki/Infographic) – informative visual representations of complex data – were created during the great attempts at tackling poverty and disease in Europe in the 19th century. Today’s masters of this technique include the Swedish doctor, academic and statistician Hans Rosling (gapminder.org), whose dynamic infographics are renowned for changing people’s perceptions of global problems.

UN Global Pulse notes “much of the data used to track progress toward the Millennium Development Goals (MDGs) dates back to 2008 or earlier and doesn’t take into account the more recent economic crisis.

“While this may feed a perception that there is a scarcity of information about the wellbeing of populations, the opposite is in fact true. Thanks to the digital revolution, there is an ocean of data, being continuously generated in both developed and developing nations, that did not exist even a few years ago.”

UN Global Pulse believes Big Data can be used to protect social development gains when crises strike. Rather than undoing decades of good development work and human development achievements, Big Data can help to create agile responses to crisis as it happens.

UN Global Pulse believes the same data, tools and analytics used by business can be turned to help the public sector understand “where people are losing the fight against hunger, poverty and disease, and to plan or evaluate a response.”

India 2.0: Can the Country Make the Move to the Next Level?

With the global economic crisis threatening to cause turmoil in the emerging markets of the global South, it is becoming clear that what worked for the past two decades may not work for the next two.

For India, the legacy issues of poverty still need to be addressed, and the country’s impressive information technology (IT) industry – which has driven so much of India’s growth – will face stiff competition from other countries in the global South. Some argue that if the IT industry hopes to keep growing and contributing to India’s wealth, things will need to change.

Unlike China, where heavy investment in infrastructure and a strong link between government and the private sector has driven the impressive manufacturing boom in the country, in India the government has de-regulated and taken a back seat, leaving the private sector and entrepreneurs to drive the change and do the innovation.

Many believe various areas need urgent attention if India is to continue to enjoy good growth rates in the coming years. Areas in need of attention include infrastructure, healthcare and education (thesmartceo.in), in particular the knowledge to work in the information technology industry of the 21st century.

One of the founders of Indian outsourcing success Infosys (infosys.com), executive co-chairman Senapathy Gopalakrishnan, told Britain’s Telegraph newspaper, “So many people’s lives have been changed by IT in India.

“People from the middle class and lower middle class have become global employees and have the opportunity to work with some of the best companies in the world. But the challenge for India is that this industry can only create so many jobs. IT is not going to solve the unemployment problem in India.”

But the coming next wave of change in information technology is an opportunity to be seized to reduce unemployment if enough people are educated to handle it.

According to Gopalakrishnan: “I strongly believe, and it’s backed up by data, that there is a shortage of computer professionals everywhere in the world, including India. The application of computers is growing dramatically and will continue to grow dramatically over the next 20 to 30 years. We have to train and create the workforce necessary to grow this industry.”

Various media stories have called this next phase India 2.0. If India 1.0 was the highly successful information technology outsourcing industry developed in the late 1980s, through the 1990s and 2000s, then India 2.0 is the next wave of IT innovation being driven by Big Data, automation, robotics, smart technologies and the so-called “Internet of things.”

Big Data is defined as the large amounts of digital data continually generated by the global population. The speed and frequency with which data is produced and collected – by an increasing number of sources – is responsible for today’s data deluge (UN Global Pulse). It is estimated that available digital data will increase by 40 per cent every year. Just think of all those mobile phones people have, constantly gathering data.

Processing this data and finding innovative ways to use it will create many of the new IT jobs of the future.

“We are living in a world which is boundary-less when it comes to information, and where there is nowhere to hide,” continues Gopalakrishnan, “If you have a cellphone, somebody can find out exactly where you are. Through social networks you’re sharing everything about yourself. You are leaving trails every single moment of your life. Theoretically, in the future you’ll only have to walk through the door at Infosys and we’ll know who you are and everything about you.”

Unlike in the late 1980s, when India was the pioneer in IT outsourcing for large multinational companies and governments, competition is fierce across the global South. The mobile-phone revolution and the spread of the Internet have exponentially increased the number of well-educated people in the global South who could potentially work in IT. China, the Philippines, Kenya, Nigeria and Ghana are just some of the countries heavily involved in this area.

If India fails to meet the India 2.0 challenge, it risks seeing its successful companies and entrepreneurs leaving to work their magic elsewhere in Asia and the new frontiers of Africa, just as many of its best and brightest of the recent past became pioneers and innovators in California’s Silicon Valley.

India’s IT sector contributed 1.2 per cent to the country’s gross domestic product (GDP) in 1998; by 2012, this was 7.5 per cent (Telegraph). The IT industry employs 2.5 million people in India, and a further 6.5 million people indirectly. IT makes up 20 per cent of India’s exports and, according to the National Association of Software and Services Companies (nasscom.in), the industry has revenue of US $100 billion.

India is now the IT and outsourcing hub for more than 120 of the Fortune 500 companies in the United States.

Out of India’s 3.5 million graduates every year, 500,000 are in engineering – a large pool of educated potential IT workers. India produces the world’s third largest group of engineers and scientists, and the second largest group of doctors.

IT has become a route that catapults bright Indian youth into 21st-century businesses and science parks and to the corporations of the world.

One visible example of the prosperity brought by IT services in India is the booming technology sector based in the city of Bangalore (also called Bengaluru) (http://en.wikipedia.org/wiki/Bangalore).

Reflective of the contradictions of India, Bangalore has 10 per cent of its workforce now working in IT, but also 20 per cent of its population living in urban slums.

The nearby Electronics City (elcia.in) is considered “India’s own silicon valley and home to some of the best known global companies.”

To date, aspects of India 2.0 are already taking shape.

One company is called Crayon Data (crayondata.com). It uses Big Data and analytics to help companies better understand their customers and increase sales and deliver more personal choices.
Edubridge (http://acumen.org/investment/edubridge/) is helping to bridge the gap for rural youth with varied education backgrounds and long-term jobs. Edubridge trains youth for the real needs of employers to increase the chances they will get a job. This includes jobs in the IT business process outsourcing sector and banking and financial services.

Infosys is working on innovations for the so-called “Internet of things,” in which smart technologies connect everyday items to the grid and allow for intelligent management of resources and energy use. Infosys is developing sophisticated software using something called semantic analytics – which analyses web content (http://en.wikipedia.org/wiki/Semantic_analytics) – to sort through social media and the Internet to track customer responses to products.

Elsewhere, former Infosys Chief Executive Nanden Nilekani is involved in a Big Data innovation to address the problem of social and economic exclusion of India’s poor. Called Aadhaar (http://uidai.gov.in/), the government-run scheme is gathering biometric data on every Indian to build the world’s largest biometric database. After being enrolled and having fingerprints and iris scans taken, each individual is given a 12-digit identification number. So far 340 million people have been registered with the scheme, and it is hoped 600 million will be registered by the end of 2014.

The idea is to use a combination of access to mobile phones and these unique ID numbers to widen access to all sorts of products and services to poor Indians, including bank accounts for the millions who do not have one. Many people, lacking any identity or official acknowledgment they exist, were prevented from engaging with the formal economy and formal institutions. Being able to save money is a crucial first step for getting out of poverty and it is hoped information technology will play an important role in achieving this.

China Sets Sights on Dominating Global Smartphone Market

The rise of smartphones – mobile phones capable of Internet access and able to run ‘apps’ or applications – is the latest wave of the global connectivity revolution. Mobile phones rapidly made their way around the world to become almost ubiquitous – the most successful take-up of a piece of communications technology in history – and now smartphones are set to do the same. The number of mobile phone subscriptions in the world surpassed 6 billion in 2012 (out of a population of 7 billion) and, according to the International Telecommunications Union (ITU), the number of mobile phones will exceed the world’s population by 2014.

Over the last five years, with the increasing popularity of smartphones, the focus of the mobile industry has shifted from voice and messaging to apps and data services.

Smartphones are complex pieces of technology and any country that can develop the capability to make them and innovate is set to make a lot of money.

The high export value potential of designing and making “computer equipment, office equipment, telecommunication equipment, electric circuit equipment, and valves and transistors” was flagged up as a priority for developing nations back in 2005 at a UN meeting looking for “New and Dynamic Sectors of World Trade” (UNCTAD).

At present, smartphones have a long way to go to surpass old-style mobile phones: by the end of 2016, according to Portio Research (portioresearch.com), the number of non-smartphones in the Asia-Pacific region alone will still be bigger than the entire worldwide number of all smartphones. Even so, it’s predicted that by 2016, there will be 555 million active smartphones in China alone, as well as half a billion smartphones in Europe by the end of 2014. By 2013, North America’s smartphones will make up 50 per cent of all mobile phones. All in all, a lucrative market.

The main factor holding back the rise of smartphones is price. Smartphones tend to cost more than a basic mobile phone. But as China gets more heavily involved in the smartphone marketplace with its own smartphone and mobile phone brands, low income consumers will find themselves with a wider choice of affordable and powerful smartphones, each one a mini-computer.

Out of the 10 largest global manufacturers of smartphones, four are Chinese: Lenovo, Yulong, Huawei and ZTE (Gartner).

Huawei (http://www.huawei.com/en/), the world’s biggest smartphone seller (according to research firm Canalys) (canalys.com), has started to move some of its design team to London in the United Kingdom, to better tailor its products for foreign markets. It has revenues each year of US $35 billion.

China’s mobile phone market is vast, accounting for a third of all smartphones sold in the world. Getting a foothold in this marketplace places a company in a very strong position to build the expertise and capital to push into the wider global marketplace. And that is what Chinese brands are starting to do. So far, Chinese exports of branded smartphones make up a fifth of those sold around the world (Canalys).

The big global competitors to date have been South Korea’s Samsung (samsung.com) and the American Apple brand (apple.com). Other large competitors are Canada’s troubled Blackberry and Finland’s Nokia.

To compete with them, popular and successful Chinese brands include Xiaomi (xiaomi.cn), which sells more mobile phones in China than does the American Apple brand, and ZTE (http://wwwen.zte.com.cn/en/).

For years, many of the top global brands have had their phones and the components manufactured in China. This meant Chinese manufacturers were assembling the phones but not benefiting from the high value that can be extracted from being the owner of the brand name and the originator of the innovation and holder of the copyrights and trademarks.

But now China’s Lenovo brand (http://www.lenovo.com/uk/en/), for example, has successfully pulled past U.S. electronics maker Hewlett-Packard (www.hp.com) to become the largest seller of personal computers in the world. It is also selling more mobile phones and tablet computers than personal computers.

Lenovo Chief Executive Yang Yuanqing espouses a two-part strategy to defend market share at home in China while going hard at overseas markets. Lenovo started with so-called emerging markets in Russia, India and Indonesia.

“We have very aggressive plans to explore overseas markets,” Lenovo’s mobile phone division head Liu Jun told China Daily. “We hope the overseas market will contribute more than half of Lenovo’s total smartphone revenue in the long run.”

Xiaomi founder Lei Jun is considered part of a new generation of dynamic Chinese technology leaders. His casual clothing and charismatic public presentations have had some equate him to the late Apple founder Steve Jobs. But Jun is not happy with selling smartphones and instead sees the company’s future in software and that the phones are just a tool to access the software. Xiaomi hopes to make even more money from selling games, running online marketplaces and offering social media.

The Chinese-made smartphone brand Coolpad (http://coolpadamericas.com/) – made by Yulong Computer Telecommunication Scientific Co. – is the third best-selling in the Chinese marketplace, surpassing Huawei and Apple and has global annual revenue of US $1.8 billion, according to Forbes magazine. Sino Market Research found 10.2 per cent of China’s smartphone users own a Coolpad, behind Korean brand Samsung and China’s Lenovo.

Coolpad has succeeded by investing heavily in research and development (R&D) and innovation to make the phones cheap but also powerful.

Innovations include technology that lets users have more than one phone number for the same phone by being able to connect to two different network technologies. The phones also include security and privacy protections that make them popular with businesspeople and government officials.

The Coolpad brand has also been frenetic in launching different models of the phones to appeal to its customers. In 2012, it launched 48 different models, selling for between US $50 and US $500.

Coolpad was launched in 2012 in the US as part of the company’s global expansion plans.

China has placed innovation at the core of its economic development policies. China increased its R&D spending in 2009 to US $25.7 billion, a 25.6 per cent rise over 2008, according to Du Zhanyuan, vice minister of the Ministry of Science and Technology. In 2011, China surpassed South Korea and Europe in total patents filed and was in a neck-and-neck race with Japan and the United States.

China now boasts twice as many Internet users as the United States, and is the main global maker of computers and consumer electronics, from toys to games consoles to digital everything.

China is also on course to become the world’s largest market for Internet commerce and computing.

The drive to change and transform China’s global economic role was promoted in 2011’s Beijing International Design Week (http://www.bjdw.org/en/), with its theme of transforming “Made in China to Designed in China.”

Update: Huawei Loses Millions Of Users As Serious New Threat From China Gets Real

"Make no mistake—Xiaomi intends to entice Huawei consumers with upgraded phones such as the recent Mi 10 Pro, better able to compete with Huawei’s flagships in overseas markets. The company is also making a feature of its “easy access to Google,” as its marketing goes head to head with its larger Chinese rival. Right now, Xiaomi has a unique opportunity to strip away market share with Huawei helpless on the Google front. And it seems that millions of Huawei users outside China who want to maintain Google on their phones are already voting with their wallets."

Mobile Phone Microscopes to Revolutionize Health Diagnostics

 

Mobile phone usage has increased hugely across the global South in the past five years. In Africa, the number of mobile phone subscribers reached 545 million in 2013, while there are 3.5 billion mobile phone users in Asia and the Pacific (ITU). Some 93 million people in Africa and 895 million in Asia and the Pacific have mobile phone Internet access (ITU).

“Every day we are moving closer to having almost as many mobile-cellular subscriptions as people on earth,” Brahima Sanou, Director of the ITU Telecommunication Development Bureau, wrote in its latest report on their growth.

The number of mobile phone subscriptions in the developing world has surpassed 5 billion and the number in the world as a whole reached 6.8 billion in 2013 (ITU), out of a world population of more than 7.1 billion. This compares to considerably lower numbers of people with access to the Internet: 2.7 billion in the world (ITU).

While many people in poorer countries have basic versions of mobile phones, the next generation of smartphones has been growing in number as prices come down (http://en.wikipedia.org/wiki/Smartphone). Examples of these smart phones include the BlackBerry, Apple’s iPhone, the Samsung Galaxy, and the Nokia Lumia. Smartphones tend to have enormous computing power and an ability to run complex ‘apps’ or applications – including public transport options, maps, restaurant and store locators, banking services and market information and resources. They can also access the Internet through Wi-Fi, and have camera and video capability.

What people can do with these feature-packed phones is limited by little other than human imagination. With the ability to store large amounts of data and images, using apps that perform a limitless range of services and tasks, smartphones can be deployed as powerful tools to tackle problems.

Science fiction sagas have long fantasized about people being able to walk around with small electronic devices that can do immensely powerful tasks, including being a medical diagnostic tool. But this science fiction dream is rapidly becoming reality in the global South.

Various initiatives and innovators are using mobile phones and smartphones to conduct medical diagnosis and gather data for medical studies in real time.

Some innovations are even turning smartphones into mobile microscopes.

Developed by the University of California, Berkeley in the lab of Professor Daniel Fletcher (http://cellscope.berkeley.edu/), the CellScope (cellscope.com) is capable of turning the camera on a cell (mobile) phone into a diagnostic microscope with a magnification of 5x to 60x. Fletcher’s lab has also pioneered work on needle-free injection technology.

The CellScope can be used for ocular imaging (technologies for visualizing and assessing a range of diseases of the eye) and for detecting tuberculosis, blood-borne diseases and parasitic worms.

Fletcher is a bioengineer and was impressed with how much mobile phone technology has proliferated across the global South.

“You don’t have to put in these copper wires (for phone lines) anymore; you have the (cell) towers. It’s big business,” Fletcher told The Scientist Magazine.

“It’s leaping over the need for infrastructure.”

Fletcher and his colleagues experimented by attaching extra lenses to smartphones. They then used the phone to image cells that had been stained with fluorescent dyes to make them easier to see. The quality of the image was so good, they were able to diagnose malaria from blood samples and tuberculosis from sputum (spit) samples.

With the addition of image analyzing software, the phone was able to automatically count the number of Mycobacterium tuberculosis bacilli. They were trying to prove you did not need conventional microscopes to do this sort of diagnostic work.

Fletcher and his colleagues are currently trialling the technology in Vietnam, India, Cameroon and Thailand.

“Technology alone doesn’t create effective health care,” Fletcher emphasizes. “It’s got to be part of a context in which the information is captured and validated and is analyzed in the right way, and treatments are then available in response to information.”

Another group from Toronto General Hospital in Canada (http://www.uhn.ca/corporate/AboutUHN/OurHospitals/Pages/TGH.aspx) has ‘hacked’ an iPhone smartphone by placing a 1 millimeter ball lens on the phone’s camera. Isaac Bogoch, an infectious disease specialist, had been investigating parasitic worm infections in children on Pemba Island off the coast of Tanzania. Along with Jason Andrews of Massachusetts General Hospital, they had been inspired by a report about how a team of researchers from the University of California, Davis had created a simple microscope out of an iPhone with a 1 millimeter lens. This makeshift microscope was used to take pictures of blood smears at a 350 times magnification and giving a 1.5 micron resolution.

“We thought that was a great idea,” Bogoch told The Scientist Magazine. Bogoch regularly works as part of an international team around the world, often in remote locations.

“We thought … we could take it to the field and see if it accurately works in a more real-world setting.”

Inspired, Bogoch got together with his colleagues and created a similar microscope with a 3 millimeter ball lens and then got to work using it to identify soil-transmitted helminth eggs in stool samples in Tanzania. When examining the stool samples of 199 children in a clinical trial using the makeshift microscope, they were able to accurately identify helminth infections in 70 per cent of the cases. They also found the iPhone microscope did very well at spotting eggs of particular parasites, such as 80 per cent of Ascaris lumbricoides infections (http://en.wikipedia.org/wiki/Ascaris_lumbricoides). The success rate dropped significantly, however, when trying to detect whipworm parasites (just over half) and hookworm infections (14 per cent).

But this is early days and an experiment: “Obviously the results aren’t perfect and there’s definitely room for improvement,” Bogoch admits.

What stands out is the potential to completely revolutionize health care by continuing to develop the capability of smartphones. With their portability and low cost, they also have the advantage of not needing a trained physician to operate them, according to David Walker, president of the American Society of Tropical Medicine and Hygiene, in The Scientist Magazine.

One of the many advantages of combining a microscope with a digital smartphone is the ability to take a picture and send it straight away to someone to make a diagnosis.

Even more exciting, Sebastian Wachsmann-Hogiu at the University of California, Davis (http://cbst.ucdavis.edu/people/sebastian/) is adapting mobile phones to undertake spectroscopy (http://en.wikipedia.org/wiki/Spectroscopy), using diagnostic test software to analyze samples on the spot. This, when successful, would be akin to the capabilities first mooted in the science fiction television and film series Star Trek (startrek.com). In Star Trek, the doctor is able to use a small handheld digital device to quickly diagnose what ails somebody.

The potential for this technology in the global South is significant. Aydogan Ozcan at the University of California, Los Angeles, who is also working on mobile phone microscopes, believes this is as significant as the dawn of the personal computer: “If you look at the early computers, they were bulky, they were extremely expensive,” he says.

But now computers “are portable … and almost anyone can afford them. The same thing is going on today (with microscopy). We are miniaturizing our micro- and nano-analysis tools. We’re making them more affordable; we’re making them more powerful.”

It looks like this science fiction dream will soon become today’s reality.

Published: July 2013

Development Challenges, South-South Solutions was launched as an e-newsletter in 2006 by UNDP's South-South Cooperation Unit (now the United Nations Office for South-South Cooperation) based in New York, USA. It led on profiling the rise of the global South as an economic powerhouse and was one of the first regular publications to champion the global South's innovators, entrepreneurs, and pioneers. It tracked the key trends that are now so profoundly reshaping how development is seen and done. This includes the rapid take-up of mobile phones and information technology in the global South (as profiled in the first issue of magazine Southern Innovator), the move to becoming a majority urban world, a growing global innovator culture, and the plethora of solutions being developed in the global South to tackle its problems and improve living conditions and boost human development. The success of the e-newsletter led to the launch of the magazine Southern Innovator.
