Solar-Powered Mobile Clinics to Boost Rural Healthcare in Africa

Around the world, innovative thinking is finding new ways of using solar power technology to bring electricity to underserved areas of the global South. Innovators are experimenting with new technologies, new business models and new ways to finance getting solar power into the hands of the poor.

One recently launched new solution is a solar-powered mobile health clinic that is bringing 21st-century medical diagnostic services to rural areas.

The US $250,000 Solar Powered Health Centre has been built by the Korean technology company Samsung (http://www.samsung.com/africa_en/news/localnews/2013/samsung-launches-solar-powered-health-centre-model-to-bring-quality-healthcare-to-rural-areas).

A truck packed with medical equipment that draws electricity from solar panels, it is traveling to rural, underserved parts of sub-Saharan Africa.

The truck is seven metres in length and comes packed with medical goodies, including a fully equipped eye and blood clinic and a dental surgery. It hopes to make it easier to reach the six in 10 residents of sub-Saharan Africa who live in rural areas, and who are often very far from affordable medical services. There is a blood analyzer, spectacle repair kit, and a non-contact tonometry test to measure the inside of a person’s eye. People can also be tested for HIV, malaria and many other conditions.

Samsung (samsung.com) developed the truck as part of its efforts to create “Built for Africa” technologies. The truck was built in Johannesburg, South Africa, helping create local jobs and skills.

Samsung hopes to scale the initiative to a million people in Africa by 2015.

The clinics were launched in Cape Town at the 2013 Samsung Africa Forum and are being rolled out by Samsung Electronics Africa (http://www.samsung.com/africa_en/#latest-home) as part of what the company calls a “large-scale medical initiative on the continent”.

The roaming trucks will be staffed by qualified medical professionals and will educate people about the importance of preventive medical screening.

Targeted conditions include diabetes, high blood pressure, tooth decay and cataracts. The clinics will also conduct public health education campaigns about the importance of preventive medicine (http://en.wikipedia.org/wiki/Preventive_medicine).

“What many see as minor health issues will not only get worse over time, but will affect other aspects of quality of life. The child that cannot see properly cannot learn properly,” said Dr. Mandlalele Mhinga, a member of the Nelson Mandela Children’s Hospital (http://nelsonmandelachildrenshospital.org/). “Mobile solutions help address this issue by making medical services accessible to more people in rural areas, and educating them about health care at the same time.”

The mobile clinics hope to reduce the vast difference between the quality of health care available to rural residents and people in urban areas.

Even in countries such as South Africa with the highest level of development in the region, medical care coverage is patchy and unreliable. For those who can afford it, 20 per cent of the population, there are private medical schemes. But everyone else must rely on an over-stretched and under-funded public health sector.

Samsung has based this innovation on its first-hand experience with providing medical services to rural areas in Africa.

“This experience has shown us how desperately medical treatment is needed across the continent, and inspired us to develop a sustainable and innovative solution to reach the people who need it most,” said Ntutule Tshenye, Business-to-Government and Corporate Citizenship Lead for Samsung Africa. “While our CSR (corporate social responsibility) strategy in Africa is largely focused on education, our efforts to enrich lives will not be felt if people’s basic needs, such as access to healthcare, are not met.”

Samsung’s “Built for Africa” product range (http://www.samsung.com/africa_en/africancitizenship/home4.html) also has a wide range of other projects and initiatives to boost health and living standards on the continent. These include education programmes, such as the Samsung Electronics Engineering Academy, Samsung Solar Powered Internet Schools, the Samsung Power Generator, and the Samsung eLearning Centres.

Samsung Electronics Co., Ltd. is a consumer electronics multinational and employs 227,000 people worldwide.

More Futuristic African Cities in the Works

It has been well documented that China is undergoing the largest migration in human history from rural areas to cities. But this urbanization trend is occurring across the global South, including in Africa, as well. According to the UN, more than half the world’s population already lives in cities, and 70 per cent will live in urban areas by 2050. Most of the world’s population growth is concentrated in urban areas in the global South.

These emerging urban areas represent vast opportunities for innovators. Innovators will be needed to build them, and in turn they will provide modern facilities for innovators to operate in and engage with the global economy. And they will connect innovators to 21st-century information technology.

But while the government in China engages in significant planning and preparation to facilitate movements to urban areas – often building entire cities from scratch (http://www.time.com/time/photogallery/0,29307,1975397,00.html) – that has not been the case in Africa. People in Africa are on the move because they are seeking out opportunities, but much of this movement has been poorly planned and not well thought out.

But now more and more African governments are grappling with how to call time on chaotic and haphazard development and build sustainable, planned cities that will significantly improve human development and quality of life.

Across Africa, a host of ambitious new cities and urban developments are in the works.

Kenya’s Konza Technology City (konzacity.co.ke) is planned as a new centre 60 kilometres from the capital, Nairobi. Calling itself a “world-class technology hub and a major economic driver for the nation”, it offers a high-tech vision full of ultra-modern buildings and houses in order to spur the future growth of Kenya’s technology industry.

It is hoped Konza will create 100,000 jobs by 2030. There will be a central business district, a university campus for 1,500 students, a residential community, and parks and wildlife in green corridors.

The groundbreaking ceremony occurred on January 2013 but the Kenyan Ministry of Lands and Housing has halted operations to allow for greater community engagement, according to Urban Africa. A dispute had erupted with the current landowners who wanted to be better consulted about the development and had accused the government of locking them out of the physical planning process.

Tatu City, Kenya (tatucity.com) bills itself as “by Kenyans, for Kenyans”. It is being built by Rendeavour (rendeavour.com), the urban development division of Moscow-based Renaissance Group (rengroup.com), one of the largest urban developers of land in Africa. It joins Konza Technology City as a flagship project for the government’s Vision 2030, hoping to turn Kenya into a middle-income country and a role model for other countries in East Africa.

Tatu City is 15 kilometres from Nairobi. It will take up 1,035 hectares and will be completed in 10 phases. Construction began in May 2012 and is scheduled to be completed by 2022.

It is selling safety and a “beautiful urban environment” just a short journey away from Nairobi’s existing Central Business District. Tatu City wants to be “a model of the African city of the future” as a “dynamic mixed-use, mixed-income environment that will be home to an estimated 70,000 residents and 30,000 day visitors”.

Just 25 minutes from Jomo Kenyatta International Airport, it promises to be one of “the most modern, well-planned urban developments in East Africa”.

In Ghana, a number of innovative projects in development reflect the country’s impressive economic growth and information technology achievements in the past decade.

Two cities are being designed by Rendeavour. One, Appolonia, is being built in the Greater Accra area while the second, King City, is being built on the west coast of the country where there is an oil and gas boom underway.

Both will have houses, retail and commercial centres, schools, healthcare facilities and other social services.

“Our objective is to provide the basic infrastructure, planning and necessary management framework in creating satellite cities that reverses the current trend of unplanned development and urban congestion in most of Africa’s growing cities,” Tim Beighton of Rendeavour told CNN.

These projects are in an advanced stage, with all plans completed and approved by the government, according to their websites.

Appolonia City of Light near Accra (appolonia.com.gh) – due to break ground in the third quarter of 2013 – capitalizes on Accra’s status as one of Africa’s fastest-growing urban areas. The Appolonia development will be a “planned, sustainable, mixed-use and mixed-income city” to build a “work-live-play” community for 88,000 people living in 22,000 homes.

It will be built 30 kilometres northeast of Accra’s central business district and will have retail, commercial and industrial space combined with tourism, social and recreation facilities.

King City in Takoradi (kingcity.com.gh) calls itself “Western Ghana’s new holistic city”. It will offer homes, shops, offices, industries and public places. The plan includes building 25,000 new homes and, importantly, over 30 per cent of the city will be allocated for green space. It will take up 1,000 hectares on the outskirts of Sekondi-Takoradi.

Elsewhere in Accra, the Hope (Home Office People Environment) City (http://www.rlgghana.com/index.php/2013-02-07-11-25-04.html) is a much more ambitious concept. It is one of a cluster of projects in Africa focused on building the infrastructure for a 21st century, high-tech future. Costing US $10 billion, it will be built outside Accra and is focused on boosting Ghana’s already established reputation in the field of information and communications technology. It will be home to 25,000 people and create jobs for 50,000. There will be six towers including a 75-storey, 270 metre building that hopes to be the highest in Africa.

It is being financed by RLG Communications, a mix of investors and a stock-buying scheme.

There will be an assembly plant for high-tech products, business offices an information technology university, a hospital and restaurants, theaters and sports centres.

The design is hyper-modern and tries to create a vertical office environment that is dense and reduces the amount of time it takes to get around and circulate between businesses in the complex.

Eko Atlantic on Victoria Island in Lagos, Nigeria (ekoatlantic.com) is a coastal residential and business development that calls itself “The New Gateway to Africa”. To ease pressure in an already crowded city, it is being built on 10 square kilometres of reclaimed land from the Atlantic Ocean. It will be able to house 250,000 people and give work to 150,000.

The story began in 2003 when the Lagos State government was looking for a solution to protect the Bar Beach area of the city from coastal erosion. Land is being reclaimed from the sea and it will make up an area the equivalent of Manhattan in New York City. Just like Manhattan, it is hoped Eko Atlantic will become the new financial centre for West Africa by the year 2020.

Kilamba, or Nova Cidade de Kilamba (https://www.facebook.com/media/set/?set=a.231897596836631.80284.228497773843280), 30 kilometres outside Luanda, Angola is being built by the China International Trust and Investment Corporation (http://www.citic.com/wps/portal). It is on a vast scale and is designed to be home to 500,000 people with apartment blocks and commercial spaces. It has cost so far US $3.5 billion and is part of a government pledge to provide a million new homes within four years. Kilamba has come in for criticism for not being affordable enough for ordinary Angolans and for having much of the site unoccupied. With the apartments too expensive for ordinary Angolans, the government has decided to take action and ordered the prices to be reduced and made more affordable, according to Angola Press .

La Cite du Fleuve in the Democratic Republic of Congo (lacitedufleuve.com) is  a more conventional luxury housing development built on two islands in the capital, Kinshasa. Kinshasa, despite its problems and the turmoil from an ongoing civil war, is one of the continent’s fastest-growing cities. Developed by Hawkwood Properties, La Cite du Fleuve will need to reclaim 375 hectares of sandbanks and swamps to be able to build a collection of riverside villas, offices and shopping centres. It is is planned to take 10 years to complete.

And finally, Kigali, the capital of Rwanda, wants to transform itself into the “center of urban excellence in Africa”.

The 2020 Kigali Conceptual Master Plan (http://www.kigalicity.gov.rw/spip.php?article494) hopes to create a regional hub for business, trade and tourism, by building a mix of commercial and shopping districts with glass skyscrapers and modern hotels, parks and entertainment facilities.

Critics, however, believe these new cities and modern developments are tackling the problems of urban development by bypassing most of the population. They argue they are just developments for those with money who can buy their way out of the chaos and lack of planning of current African cities.

“They are essentially designed for people with money,” Vanessa Watson, professor of city planning at the University of Cape Town, told CNN. She believes most of the plans are unsustainable “urban fantasies” detached from the reality of African poverty and informal living.

But while it is easy to criticize these ambitious projects, they reflect not only optimism for the continent’s future but also a clear recognition the continent will not be able to get wealthier without modern cities and infrastructure in keeping with a 21st-century economy.

African Infrastructure Dreams Back on Agenda

Africa’s patchy infrastructure is not keeping pace with the continent’s economic growth.

Satellite photos of Africa at night show a place where light is concentrated overwhelmingly in the South – primarily South Africa – and in the North, with a sprinkling of lights on the west and east coasts (http://geology.com/articles/satellite-photo-earth-at-night.shtml).

This is just one visually arresting way to view the much larger problem of the continent lacking 21st-century infrastructure – from roads to airports to sewage and water services to harbors and rail connections. All are in desperate need of an upgrade.

The World Bank says only one in four people has access to electricity in sub-Saharan Africa. According to the International Energy Agency (IEA), the region will require more than US $300 billion in investment to achieve universal electricity access by 2030.

This lack of modern infrastructure is clashing with Africa’s impressive economic growth in recent years. The continent will be home to seven of the 10 fastest growing economies in the world by 2015, according to the IMF. Yet still too much of this is a reflection of a booming resource economy, which sounds impressive in numbers, but still leaves much of the continent’s population living in a day-to-day world of underdevelopment and poverty.

Africa desperately needs further investment in infrastructure. The good news is that a mix of positive developments is coming together to breathe life into efforts to upgrade the continent.

One is a new campaign to mobilize Africa’s wealthiest to stump up the necessary funds to conduct feasibility studies to lay the groundwork for a big boost to infrastructure spending in the coming years. Another is a flurry of new pledges from the United States to spend more in Africa to increase access to energy – a necessary precondition to improvements to living standards. China, too, is to continue to grow its already substantial investments in Africa.

For innovators, better infrastructure across Africa will make it easier to export products, connect with markets and customers and gain access to new technologies and products available to others around the world.

The Made in Africa Foundation (madeinafricafoundation.co.uk) hopes to turn to Africa’s wealthy global community to help with funding the feasibility studies required to unleash a new wave of infrastructure spending and building across the continent.

Africa takes up 30 million square kilometers (UNEP), is home to approximately 15 per cent of the world’s population and has 60 per cent of the world’s potential agricultural land. Yet, just 34 per cent of Africa can be reached by road and only 30 per cent has access to electricity. One estimate has placed the cost of meeting Africa’s power and transport needs at US $28 trillion by 2050.

That is a vast amount of money, and nobody will commit those sums unless they know that work has gone into planning for this infrastructure and that people are thinking long-term. This is where the Made in Africa Foundation wants to make a difference: it is hoping to get Africa’s wealthy to contribute US $400 million to fund feasibility studies which in turn will kick-off a US $68 billion first phase in investment into roads, railways, ports and energy.

“In 2009, there was (US) $150bn (billion) available to spend, but no bankable infrastructure projects in Africa,” that these funds could be directed towards, said the Foundation’s George Brennan. “These figures should make us angry – the problem is not the availability of funding but the fact that projects are not in a condition to be funded.”

Just as a global diaspora of Indians and Chinese have been instrumental in economic growth and development in India and China in the past two decades, so it is hoped the same formula can be applied to the equally substantial, successful and wealthy African diaspora.

“African Americans spend (US) $1 trillion every year in their economy, but what do they spend on Africa? About 0.01 percent,” said Chris Cleverly, Director of the Made in Africa Foundation. “They have the wherewithal to make profound differences – personally, and by lobbying their pension funds, investment advisers and government to invest in Africa on the basis that it provides good returns.

“It was China and India’s diasporas that developed them – it is the same with Africa’s now.”

Ozwald Boateng (http://ozwaldboateng.co.uk), the dynamic Ghanaian-descended London tailor who built his reputation on a quirky and modern take on traditional British bespoke suits, took the lead along with the Ugandan Prince Hassan Kimbugwe (http://www.cdrex.com/prince-hassan-kimbugwe/1251509.html) and former British barrister Chris Cleverly.

Boateng’s reputation and fame rose along side the buzzing British capital throughout the 2000s. But now he is reaching back to Africa to lead a campaign to substantially raise the level of investment in the continent’s creaking, antiquated or non-existent infrastructure.

He is trying to rally Africa’s wealthiest business leaders to contribute to creating a 21st-century African infrastructure of roads, railways, ports and power supplies. Made in Africa is tackling the fact many big global investors are willing to invest in Africa but find it difficult to do so. Much has to be done before an investor can come along and start, for example, building a new road network or airport. Local governments need to do the initial site survey and environmental impact studies and develop a larger vision for where they would like their country to go and how its cities are to develop.

The campaign got underway with a star-studded gala event earlier this year in Marrakech, Morocco, at the African Banker Awards (http://www.ic-events.net/awards/african_banker_awards_2013/). It also comes with a film, Our Future, Made in Africa, to help explain the campaign and the company.

Some of the people who attended included Nigerian philanthropist Tony Elumelu, Angola’s richest woman Isabel dos Santos and Sudanese telecoms mogul Mo Ibrahim.

“This is the start of fully understanding what Africa can do for itself,” said Boateng. “The Chinese managed to build a railway across China; the Japanese have the bullet train – we need to get past thinking about why it’s difficult to create the roads and railways that Africa needs and just get on with it.”

The Foundation is being supported by the African Development Bank (http://www.afdb.org/en/), a long-time supporter of African infrastructure investment through loans and technical assistance.

An additional boost to African development comes from a recent U.S. government pledge to spend US $7 billion over the next five years in Africa to improve access to energy. Energy is the needed fuel for any significant improvements to human development over the long-term.

U.S. President Barack Obama announced “Power Africa” (http://www.whitehouse.gov/the-press-office/2013/06/30/fact-sheet-power-africa) while he was in Cape Town, South Africa on his recent African tour. At the heart of Power Africa is the pledge to double access to power in Africa. According to medical journal The Lancet, 3.5 million Africans die every year due to indoor air pollution – a figure larger than those who die every year from malaria and HIV/AIDS combined. The pollution results from the fumes caused by burning fuel for cooking, warmth and light.

President Obama promised the funding to help governments in Ethiopia, Ghana, Kenya, Liberia, Nigeria and Tanzania. The funds will be used to boost access to electricity for 20 million households. Funds will also be used to help Angola and Mozambique modernize their energy export sectors.

Power Africa will act as a go-between to encourage links and deals between American energy companies and African partners.

On top of this, Power Africa is being supplemented by an additional US $10 billion in private sector contributions, including a commitment from the General Electric Company to bring 5,000 megawatts of affordable energy to Tanzania and Ghana.

In total, the US estimates it will take US $300 billion in additional funds to bring full power to sub-Saharan Africa.

For the past decade, the biggest change in Africa’s infrastructure story has come from the growing role played by China. China has become Africa’s largest single trading partner, with bilateral trade reaching US $166 billion in 2011 – a jump of 33 per cent from 2010. The total volume was valued at $198.5 billion in 2012 and is expected to surpass $380 billion by 2015.

And much, much more has been promised to come: China’s President Xi Jinping (http://en.wikipedia.org/wiki/Xi_Jinping) renewed a pledge to offer US $20 billion in loans to Africa in March 2013 (Reuters). Much of this is going to electricity-generation projects.

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.

Small Fish Farming Opportunity Can Wipe Out Malnutrition

Pioneering work to boost diets across the global South is turning to the smallest of fish. While small in size, tiny fish are packed with nutrition when eaten whole, as they are in many cultures. Often these fish come packed with vitamin A, iron, zinc, calcium, protein and essential fats – all necessary elements to eradicate malnutrition and hidden hunger, especially among women and children.

It is estimated that 684,000 child deaths worldwide could be prevented by increasing access to vitamin A and zinc (WFP).

Iron deficiency is the most prevalent form of malnutrition worldwide, affecting an estimated 2 billion people. Iron deficiency is impairing the mental development of 40 to 60 per cent of children in developing countries (UNICEF). The World Health Organization says that eradicating iron deficiency can improve national productivity levels by as much as 20 percent.

Vitamin A deficiency affects approximately 25 per cent of the developing world’s pre-schoolers. It is associated with blindness, susceptibility to disease and higher mortality rates, and leads to the death of approximately 1 to 3 million children each year (UN).

This devastating evidence shows the need to find effective food solutions to eradicate these nutrient deficiencies. Access to affordable nutrient-rich food is also key to social and political stability. Already, there is serious unrest in many countries around the world because of food-price inflation.

Finding ways to boost nutritional health that are sustainable, low-cost and do not require substantial use of resources will have the best success in the poorest areas.

A number of studies suggest one solution may be eating more small fish. In many countries, these species are eaten as part of the diet, but often not in large enough quantities to address hunger and malnutrition. Small fish species are a remarkable food source because they are usually eaten whole, bringing greater nutritional benefits.

Small fish have a long history in human diets. Anchovies (http://en.wikipedia.org/wiki/Anchovy) are used  in many cuisines, for example.

A study conducted between 2010 and 2013 in Bangladesh and Cambodia by Dr. Shakuntala Haraksingh Thilsted, Senior Nutrition Adviser to WorldFish (worldfishcenter.org), found that the eating of small fish in both countries gave a significant boost to daily diets and massively improved nutrition and health. The project, called Linking Fisheries and Nutrition: Promoting Innovative Fish Production Technologies in Ponds and Wetlands with Nutrient-dense Small Fish Species, was supported by the International Fund for Agricultural Development.

People in both countries still currently suffer from undernutrition and micronutrient deficiencies.

In rural areas of Bangladesh and Cambodia it found 50 to 80 per cent of total fish consumed were small fish. The quantities consumed during each meal were small but they occurred in diets frequently. Typically, they were eaten whole, with the head, viscera (internal organs) and bones consumed. This meant consuming small fish packed a punch, giving the eater a dose of calcium, vitamin A, iron and zinc.

More specifically, the study found the iron-rich Mekong flying barb (Esomus longimanus) (http://www.iucnredlist.org/details/169546/0) – eaten as part of a meal of rice and sour soup with its head intact in Cambodia – could provide 45 per cent of the daily iron requirement for a woman.

Malnutrition is also a serious problem in Bangladesh. Half the population lives below the poverty line and diets are poor in delivering necessary vitamins and minerals. This is damaging to peoples’ physical and mental health.

The study found existing fish aquaculture methods in Bangladesh were inefficient. But new technologies provide an opportunity to increase the quantity of fish harvested and increase household incomes. By using highly efficient low-risk polyculture systems – basically combining small, nutrient-dense fish with high-value fish such as carp or freshwater prawn – it is possible to significantly increase the quantity of fish produced.

Another one of the new techniques includes increasing pond depth, which conserves broodfish (http://en.wikipedia.org/wiki/Broodstock). Broodfish are the mature fish used for the production of eggs or sperm and are also called spawners.

The study estimated a production of 10 kilograms per pond per year of fish spread across the 4 million small ponds in Bangladesh has the potential to meet the recommended dietary intake for 6 million children in the country.

The work in Bangladesh to boost the production of small fish has inspired similar initiatives in Sunderbans, West Bengal, India and in Terai, Nepal. Initiatives in Cambodia and Kenya have also developed meals for young children by combining powdered rice or maize with small fish.

And in Africa, some are calling for more use of aquaculture as an alternative to dwindling fish sources. For sub-Saharan Africans, fish can make up 22 per cent of the protein in their diet.

As populations on the continent quickly rise, marine fisheries are beginning to be over-exploited. The Food and Agriculture Organization of the United Nations and WorldFish are calling for an aquaculture revolution on the continent to move away from the old approach of just using ponds located on farms. To make a real impact, both organizations argue, there needs to be a partnership between smallholder farmers and others to build a commercial fish farming sector.

“Per capita fish supplies in Africa are dwindling,” Malcolm Beveridge, director for aquaculture at WorldFish, one of the 15 CGIAR research centers (Consultative Group on International Agricultural Research) (http://www.cgiar.org/cgiar-consortium/research-centers/), that generate and disseminate knowledge, technologies, and policies for agricultural development. “In Malawi, they fell from 10 kilograms to 6 kilograms per person between 1986 and 2006. Aquaculture has the potential to increase supplies of this affordable nutritious food for poor and vulnerable consumers,” he told The Guardian.
