  • Avoiding Wasting Food and Human Potential with ICTs

    Avoiding Wasting Food and Human Potential with ICTs

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Creative use of information technology in the South is helping to address two very different kinds of waste – of food and of human and community potential.

    In Ghana, a mobile phone-driven Internet marketplace is helping to improve efficiencies in farming and selling food. Another initiative is addressing the crisis in India’s villages by drawing on the diaspora of former villagers now living in urban environments around the world.

    Finding ways to efficiently trade food is crucial to keeping hunger at bay and meeting the needs of growing populations. In a report earlier this year, the UN’s Environment Programme (UNEP) found that more than half of the world’s food is wasted or discarded.

    “There is evidence … that the world could feed the entire projected population growth alone by becoming more efficient,” said Achim Steiner, UNEP Executive Director, at the launch of The Environmental Food Crisis: The Environment’s Role in Averting Future Food Crises.

    Ghana is a country that has already gained a reputation as an IT leader in West Africa (www.ghanaictawards.com). Now a clever technology based in the capital, Accra, is using mobile phones to connect farmers and agricultural businesses and associations to the marketplace. By using SMS (http://en.wikipedia.org/wiki/SMS) text messages, information from the field is gathered and collated. This can include tracking what is happening on the farm, how crops are surviving the weather, and the status of food inventories day-by-day. All the data is collected by the TradeNet website and displayed with prices and deadlines for buyers and sellers to get in touch with each other. This reduces the time and cost involved in gathering updates from thousands of people across the country.

    Launched in 2007, the service recently won the Information Communication Technology innovations contest by the World Summit Award (WAS) (http://www.wsis-award.org/about/index.wbp) of the United Nations’ World Summit on Information Society (WSIS).

    TradeNet is currently collating market data from 13 countries and proclaims itself the largest SMS-based market information service on the continent of Africa. It has more than 12,000 registered users and covers 500 individual markets.

    The service’s full name is TradeNet: Market Information on your Mobile (http://www.tradenet.biz/?lang=en), and it tracks products like ground nuts, sesame, tomato, maize and white beans. It offers market information from Afghanistan , Benin , Burkina Faso , Cameroon , Cote d’Ivoire , Ghana , Madagascar , Mali , Mozambique , Nigeria , Sudan and Togo.

    Founded by its chief executive officer Mark Davies, TradeNet is run out of the internet start-up incubator Busy Lab (http://www.busylab.com/) in Accra. Busy Lab specializes in building mobile web solutions for companies and projects involved in rural media and computing.

    While in India, villages are in crisis: As India’s economy has boomed, its small towns and villages have withered. Home to the majority of the country’s population, they are suffering declining populations and high suicide rates. India’s urban slums are where people are going; they are growing 250 percent faster than the country’s population. Yet so many people share some past connection with the country’s 260,000 ailing villages.

    And while the world has become a majority urban place, it is acknowledged the future for the environment and agriculture rests in the health of villages.

    The social media website Mana Vuru (www.manavuru.com) seeks to connect people living in cities with the villages they were born in, or where their families came from. It is about restoring the broken connection with the village in order to enhance their future development.

    As Mana Vuru declares: “Villages form the backbone of our economy. True progress, growth and prosperity can only be realized when villages become self-sustainable.”

    The site points out that “most villages are suffering from crippling infrastructure and some even lack the basic amenities like electricity and fresh water. We believe that every person who migrated to greener pastures and attained success and wealth should feel some sort of moral responsibility and do their bit for their respective villages.”

    A project of the Palette School of Multimedia (http://www.palettemultimedia.com/) in Hyderabad – one of India’s technology hubs – the site lets former village dwellers register and start meeting and connecting with fellow members of the diaspora. Together they can network to help the village address its development challenges.

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

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

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    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.

  • 3D Printing Gives Boy a New Arm in Sudan

    3D Printing Gives Boy a New Arm in Sudan

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    3D printing is rapidly going mainstream and is now starting to make a big impact in health care. One innovative solution is using the technology to manufacture artificial arms for amputees harmed by war in Africa.

    While large-scale manufacturers use the machines to fabricate products and parts, from aircraft components to furniture, it is the smaller-scale use of 3D printing machines that has been getting many working in development excited.

    3D printing (http://en.wikipedia.org/wiki/3D_printing) usually involves a desktop-sized fabrication machine that builds a three-dimensional object following instructions from a digital computer file. It is an additive process, in which material is laid down in successive layers to create an object. The technology has been around since the 1980s but only became affordable for the general public in the past five years. Typically, 3D printers are used to make prototypes — for example architectural models or machine parts — or to manufacture one-off objects without the need to turn to mass production methods. But the technology is evolving quickly and, according to The Guardian, “20% of the output of 3D printers is now final products rather than prototypes.”

    For international development, 3D printing offers the potential to close the gap between what is available in developed and developing countries. Just as the Internet has closed the knowledge gap, and enabled people around the world to access news and knowledge at the same time, so 3D printing could make it possible for technological innovations to be available everywhere. Just upload the digital plans for an object, and people can download them and print the item, wherever they are.

    Some of the more enthusiastic proponents of 3D manufacturing see it as a game-changer in access to technology. They argue it could eliminate material want and place the power of manufacturing in the hands of billions, in the same way the rapid proliferation of mobile phones and the Internet transformed access to information. That is the dreamers’ dream, but it is closer than many think.

    The conflict in the new nation of South Sudan, which separated from the Republic of the Sudan in 2011, continues and involves UN peacekeeping forces (http://unmiss.unmissions.org). The violence has killed over 10,000 (International Crisis Group) and injured many more, ruining lives through lost limbs and capabilities. One young boy, Daniel Omar, 16, lost both his hands while trying to use a tree trunk to shield himself from an exploding bomb. Losing his hands was devastating enough, but he was also so depressed at not being of full use to his family that he wished he had died that day.

    He is not alone in being harmed by the conflict. In total, an estimated 50,000 people in South Sudan are physically disabled, according to the International Committee of the Red Cross (ICRC).
    Prosthetic limbs are very expensive and so far are not a priority for medical services in the country. Saving lives is the priority, with rehabilitation an expensive luxury.

    This is where Not Impossible Labs (notimpossiblelabs.com), based in Los Angeles, California, came in. The non-profit startup founded by Mick Ebeling specializes in “crowd-sourcing to crowd-solve previously insurmountable healthcare issues.” The solutions are then made public on the Internet and explained in online media to help innovators either replicate the solutions or be inspired to come up with their own ideas.

    The lab’s ingenious solutions include BrainWriter – a way to draw using brainwaves and a computer mouse that can allow disabled artists to carry on creating. Not Impossible Labs also developed a high-tech cane for the blind that draws on sonar technology and a laser to navigate the terrain and foresee upcoming obstacles.

    Emotionally touched after learning about Daniel’s plight, Ebeling decided to act.
    “I’ve got three little boys,” Ebeling told The Guardian newspaper. “It was hard for me to read a story about a young boy who had lost his arms.”

    Project Daniel (http://www.notimpossiblelabs.com/#!project-daniel/c1imu) set out to manufacture artificial hands for Daniel without him having to leave his country and his family. Daniel was living between the Yida refugee camp in South Sudan and his home in the Nuba Mountains.

    A team from Not Impossible Labs set up the 3D printing lab in the Nuba Mountains and trained and supervised the local team to print two prosthetic arms. The design for the arm was done in the U.S. at its headquarters in Venice, California and is available for free and is open source (http://en.wikipedia.org/wiki/Open_source). A “dream team of innovators” were assembled – including the South African inventor of the Robohand (http://www.robohand.net/), an Australian MIT (Massachusetts Institute of Technology) neuroscientist and a 3D printing company owner from Northern California – to crowd-solve the challenge of making a 3D-printable prostheses. A precision engineering company, Precipart (precipart.com/home), and Intel were also drafted in to support the project.

    Not Impossible believe the spirit behind the project will be globally transformative.

    “We are on the precipice of a can do maker community that is reaching critical mass,” said Elliot V. Kotek, Not Impossible’s content chief and co-founder. “There is no shortage of knowledge, and we are linking the brightest technical minds and creative problem-solvers around the globe. Project Daniel is just the tip of the proverbial iceberg.”

    Daniel’s new artificial arm and hand took a 3D printer several days to make and cost around US $100.

    In November 2013, Ebeling travelled to South Sudan with all the equipment required to “print” Daniel a new arm: 3D printers, spools of plastic and cables.

    The plastic arm printed by the 3D printer works by allowing the wearer to flex what remains of their arm to pull various cables that act as ligaments, like in a real limb. When the user flexes and bends, the cables pull back and in turn make the fingers close and open.

    It is not a solution for every amputee. “With the technology we currently have it’s hard to help people with no arm left,” said Kotek. “There needs to be at least a little bit of a stump.”

    Shy at first, once Daniel saw the arm, he was transformed. “It was a pretty amazing thing to see this boy come out of his shell,” said Ebeling. “Getting Daniel to feed himself was a highlight that was right up there with watching my kids being born.”

    Even more impressive has been the quick adoption of the technology by the local doctor, Dr. Tom Catena, who performs all the amputations in the area.

    With two 3D printing machines left behind by Ebeling, Dr. Catena has been able to print a prosthetic arm a week.

    The machines mostly work at night when it is cool. The printer parts are then assembled by eight local people trained to operate the machines and build the arms.

    But how do they ensure, over time, this 21st-century technology doesn’t just fall into disrepair and neglect as has been seen time and again with other attempts at technology transfer? Weekly phone calls are made to check on the project and the plastic used to make the arms is sent directly from Not Impossible Labs.

    And then there is community buy-in.

    “At first these kids wanted arms that matched their skin tone, because they didn’t want to stand out,” said Kotek.

    But in time the youths have been decorating the arms in many colors and customizing them. And the arms have been given a name: the Daniel Arm.

  • 3D Home Printing Landmark: 10 Houses in a Day

    3D Home Printing Landmark: 10 Houses in a Day

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    The global South is experiencing urban growth on a scale unprecedented in human history, far outstripping the great urbanization wave that swept across Europe and North America during the 19th and 20th centuries.

    Faced with growth at this pace, governments – both national and local – often become overwhelmed by the rate of change and find it difficult to cope. One of the most common complaints urban-dwellers around the world have is about their living conditions. Even in developed countries, creating enough housing to match demand can be a struggle.

    Quality housing is crucial to human development and quality of life. Adequate living space and access to running water make a significant contribution to people’s health and well-being. Despite this obvious conclusion, millions of urban dwellers live in squalid conditions with poor sanitation, overcrowding, crime, pollution, noise and a general feeling of insecurity. Insecure people find it difficult to access stable jobs and suffer stigma for living in poor-quality neighbourhoods.

    But many initiatives are seeking to speed up the pace of home construction.

    These include the Moladi construction system from South Africa (moladi.net). Moladi uses moulds to assemble houses, so that the building skills required are minimal and easily learned. Built to a template that has been tested for structural soundness and using a design that produces a high-quality home both in structure and appearance, the Moladi system seeks to provide an alternative to makeshift homes that are structurally unsound and vulnerable to fires, earthquakes and other natural disasters.

    Another clever approach is a home and dwelling assembly system developed by architect Teddy Cruz (http://estudioteddycruz.com) (http://visarts.ucsd.edu/faculty/teddy-cruz) that allows slum dwellers to gradually construct a building in stages as they can afford it. It is earthquake-safe and fire resistant.

    Another approach turns to the fast-growing technology of 3D printing (http://en.wikipedia.org/wiki/3D_printing). This technology has gone mainstream in the past five years in the form of desktop-sized 3D printers, or fabricators as they are sometimes called. The machines assemble objects in an additive fashion – layer-by-layer – using digital designs from a computer.

    3D printers can make a complex object without having to resort to mass manufacturing. An accurate, one-off object can be created with the same precision as a machined object. Architects, for example, use the technology to make 3D models of their designs. And now a company in China is hoping to use 3D printers to make houses.

    The WinSun Decoration Design Engineering Co. (http://www.yhbm.com/index.aspx) 3D printed 10 houses in 24 hours in Shanghai’s Qinpu district, reported Business Insider.

    This landmark achievement was accomplished with a giant printer – 152 meters long, 10 meters wide, and 6 meters high – which manufactured walls for the house from a mix of construction waste and cement.

    As a sign of the confidence the company has in the innovative construction technique, it built its own 10,000 square meter headquarters in one month using the same materials. The company’s chief executive officer, Ma Yihe, is also the inventor of the technique. It is a very flexible technology and the material can be tinted different colors according to the customer’s wishes. It is cheap to work with and is also less draining on environmental resources than traditional building materials.

    The 10 houses consist of two concrete side supporting walls with glass panels at the front and back and with a triangle roof. They will be used as offices at a high-tech industrial park in Shanghai. The company has big plans, hoping to use the technology to build more homes – and even skyscrapers.

    Competition is heating up as people around the world seek to perfect 3D technology to print houses to meet the growing demand for dwellings.

    In The Netherlands, Dutch architectural firm Dus Architects (dusarchitects.com)  commissioned the development of a leviathan 3D printer so it could print entire rooms. Modeled on a much smaller home desktop version, the Ultimaker (ultimaker.com), this printer creates whole rooms that are then assembled into custom-built houses.

    The 6-meter high KamerMaker (kamermaker.com), or “room builder”, is being used in Amsterdam to build a full-size house.

    The project is called “3D Print Canal House” (http://3dprintcanalhouse.com/). The printer assembles the rooms individually, and then they are snapped together to make a house. The internal structure of the building blocks are in a honey-comb pattern, which is then filled with a foam that becomes as hard as concrete.

    “For the first time in history, over half of the world’s population is living in cities,” Dus Architects founder Hans Vermeulen told cnet.com. “We need a rapid building technique to keep up the pace with the growth of the megacities. And we think 3D printing can be that technique.

    “We bought a container from the Internet and we transformed it into one of the biggest printers on this planet.”

    This technology can also easily use recycled waste materials and lower the pollution and cost of moving building materials around. The Dus Architects prototype house is expected to take three years to complete (so, still in its early development phase) and will look like a typical Dutch canal house with a pointy, gabled roof (http://www.build.com.au/gabled-roof).

    One of the pioneering advocates for using 3D technology to address the global South’s urbanization and housing challenge has been Larry Sass, director of the Digital Design Fabrication Group (http://ddf.mit.edu/) at the Massachusetts Institute of Technology (MIT).

    Three technologies have been developed at MIT since the 1950s that have made digital fabrication possible – computer numerical control (CNC), which enables computers to control machines; computer-aided design software in the 1960s; and 3D printing in the 1980s to make solid models using digital designs.

    Sass told MIT’s Spectrum newsletter (spectrum.mit.edu) that large-scale 3D printing would mean “buildings will rise faster, use fewer resources, cost less, and be more delightful to the eye than ever before.”

    He envisions a future in which architects will be able to send their designs by computer to a 3D printer and it will then be able to start “printing” the building or a house accurately according to the original designs.

    The conventional way of making buildings has been stuck in the same approach since the 1800s, according to Sass. It uses highly skilled and extensive labour, it is slow and plagued by weather disruptions and urban congestion, and it is expensive, often using materials brought from far away.

    Digitally fabricating buildings takes a radically different approach: the building is made in a series of precision-cut, interlocking parts and then assembled on site like a jigsaw puzzle.

    “It’s the right delivery system for the developing world, because the developing world doesn’t have an infrastructure of tools, air guns, saws and power,” Sass said.

    “Design and high-quality construction is mostly for the rich,” added Sass, who was raised in Harlem, a New York City neighbourhood with high poverty levels. “I’ve always wanted to figure out how to bring design choice and architectural delight to the poor.”
