10 Technological Innovations for Developing Countries

Technological Innovations for Developing CountriesNew technological innovations for developing countries make it possible for individuals to survive and thrive in a world that is constantly advancing. Technological innovations for developing countries can provide low-cost methods to keep people safe, connected and informed, all of which are important steps in the path out of poverty. Ahead are 10 technological innovations for developing countries.

  1. Kenya’s M-PESA app allows cellphone owners to easily and securely transfer money using their phones, and is mostly used for staff salaries and child support. Launched in 2007 by Safaricom, the country’s largest mobile-network operator, the app is now used by more than two-thirds of Kenya’s adult population.
  2. The LifeStraw is a technological innovation that could solve one of the biggest challenges that impoverished countries face – access to clean water. Originally introduced in 2005, LifeStraw is a series of water purification systems capable of killing up to 99.9% of bacteria. LifeStraw’s Follow the Liters program delivers water purification systems to schools in developing countries.
  3. The world’s cheapest tablet, Aakash, is priced at $35 for students with government subsidies, or $60 in stores. The device was launched with the idea that “[t]he rich have access to the digital world; the poor and ordinary have been excluded. Aakash will end that digital divide,” according to Kapil Sibal, India’s minister of communications and information technology. Affordable and effective, the device operated perfectly under a two-hour video test in 118-degree heat that replicated the harsh summer weather in northern India.
  4. One Laptop Per Child (OLPC) seeks to empower the world’s disadvantaged children with education, distributing rugged, low-cost and low-power laptops to kids across the developing world. The little blue device costs between $400 and $500 each to distribute and enables teachers to communicate with their students through web-based applications.
  5. The world’s cheapest cellphone, developed by British carrier Vodafone, sells for just under $15. While the phone is not feature-rich, it offers the basic operations necessary — voice calling, text messaging and mobile payments. The phone launched in 2010 in India, Turkey and eight African nations.
  6. Eden Full, a mechanical engineering undergraduate at Princeton University, developed solar panels that optimize energy collection by rotating to face the sun for as much time as possible each day. The technology, known as SunSaluter, is cheap and efficient. It costs just $10 for the system, which uses 40% fewer panels than typical solar energy. Its aim is to bring solar panels to places in the developing world that have never had access to electricity.
  7. India released the Tata Swach, a $21 water filter that uses nanotechnology, requires no electricity and meets sanitation standards set by the U.S. Environmental Protection Agency. Made of rice husk ash and silver nanoparticles, the device prevents the growth of bacteria and protects against waterborne illness and viruses.
  8. Text to Change (TTC) engaged thousands of young people in Africa in politics, economics and social issues through the Voice Africa’s Future project. The project’s goal was to mobilize 150,000 young people in Africa to text their thoughts and input on the future state and actions of their nations.
  9. Dell’s computer hardware and literacy program, Youth Learning, initially launched in India but now operates in 15 countries across the world to provide grant funding and the latest technology to address the lack of basic needs that may hinder a child’s ability to learn, such as food or security.
  10. Researchers have found that providing a safe, energy-efficient wood-burning cookstove to those in the developing world can directly improve health by reducing smoke inhalation, and alleviate poverty by reducing the amount of time needed to gather wood every day. The Berkeley-Darfur Stove accomplishes this with an enhanced design featuring a tapered wind collar, small fire box opening and nonaligned air vents and ridges. Potential Energy, a nonprofit organization that specializes in adapting technology for developing countries, has distributed more than 25,000 Berkeley-Darfur Stoves in Darfur and Ethiopia.

The use of technology in developing countries is becoming more widespread and has the potential to improve basic conditions of daily life in struggling regions. Technological innovations for developing countries can also promote intellectual growth by providing unique educational services.

The Appeal and Usefulness of Web-Based Health Programs

Web-Based Health Programs
Recent advancements in technology have transformed and improved countless aspects of peoples’ lives. Some of the word’s greatest health concerns are obesity and the abuse of alcohol and tobacco. Can web-based health programs make a dent in these problems?

Web-based health programs encourage setting concrete goals and can interact with users throughout the day. They have the added benefit of 24/7 accessibility.

One example is an online tool designed for the Obesity Prevention Tailored for Health II project. The tool locates and displays health food stores, parks and recreational programs near users. It also suggests health-and-eco-friendly transportation options such as biking, walking and using public transit.

Discussed below are two examples of studies examining the usefulness of web-based health programs.

University of Washington

At the University of Washington in Seattle, researchers have been reviewing studies about the effectiveness of mobile and web-based health programs in helping users curb unhealthy behaviors such as overeating and smoking.

The team of researchers found that web-based programs helped users increase their physical activity and lose weight. Eighty-eight percent of the tested programs helped people exercise more. In addition to this, 77% of tested programs designed to help users quit smoking proved effective.

Health Affairs Journal

Health Affairs published a study examining nearly 2,000 overweight adult participants whom researchers divided into groups. In some groups, participants were given access to a social-networking intervention program, and in other groups, they were not. The program featured motivational emails and phone calls, an online discussion forum and a tool for recording food intake. Participants who used the web-based health program experienced slightly greater body mass index (BMI) reduction on average than did participants who didn’t use the program.

Overall, web-based health programs offer a promising alternative to traditional health interventions. They are generally low in cost and widely accessible. Web-based health programs have the potential both to change the way we look at health and improve countless peoples’ quality of life.

OpenMRS: Open Source Health Database for sub-Saharan Africa

Health DatabaseIn Sub-Saharan Africa, nearly one in every 25 people lives with HIV. With a population of around 1 billion people, this number is astounding. In fact, according to the WHO, those living with HIV in Sub-Saharan Africa account for nearly 70 percent of the population of HIV carriers around the entire world. There is no question that a health database would be invaluable for tracking HIV and other diseases in this region.

HIV in Sub-Saharan Africa

Although the prevalence of HIV in Sub-Saharan Africa has been declining since 2000 due to prevention education and treatment programs, but it is a slow process. And where these programs are lacking, infection rates tend to rise.

Without the proper information regarding how to protect oneself, HIV can be spread easily throughout a population. Unfortunately, HIV prevalence can only currently be reduced through prevention education and treatment programs due to the nature of the virus.

HIV or Human Immunodeficiency Virus gradually attacks the body’s ability to fight infections and diseases. With this symptom comes a serious need for medical assistance. Regrettably, medical assistance in Sub-Saharan Africa is limited in terms of accessibility and effectiveness.

One doctor, Judy Gichoya, saw how difficult it was for medical personnel to treat patients in Sub-Saharan Africa, mostly due to a lack of proper patient information. When patients come for medical help, doctors had very little idea of what the patient had received in terms of previous medical assistance and what they currently needed.

Essentially, without an efficient system for storing patient information, doctors have to dedicate more time to diagnosis and learning clerical information about the patient rather than giving treatment.

OpenMRS

As a result, Gichoya joined a group of others who noticed the same issue and were working to fix it. From here, OpenMRS was born. OpenMRS is a software platform for an open source health database well as a reference application that allows users to create a system of medical records to fit the specific needs of a hospital or health center.

According to the OpenMRS website, no knowledge of programming is necessary to use the software successfully. It is secure, easy to use, summarizes information without difficulty and allows many computers to access a server at the same time. This accessibility allows an ease of adoption and hopefully a reduction in unnecessary effort, allowing more time to be focused on patient treatment.

Aiding a Variety of Groups

Currently, OpenMRS is being used in developing countries including South Africa, Kenya, Rwanda, Lesotho, Zimbabwe, Mozambique and others. The software is currently used by non-profits, government aid groups, for-profit groups and NGO’s. This is where OpenMRS’s open source origins shine. Its ability to be modified allows it to be changed for every specific need of each user and could even potentially allow it to be used in a variety of fields.

So far, the wide adoption of the health database created with OpenMRS shows that it is not only usable but also effective. Open source technology is becoming very prevalent and it seems to be the perfect format for technology destined to help those in poverty around the world. Hopefully, this trend continues and great minds keep working on technology, improving it and making it more accessible to those in need like those who struggle with HIV in Sub-Saharan Africa.

Poverty Mapping with Help of Artificial Intelligence

Poverty Mapping with the Help of Artificial Intelligence
Poverty mapping has proven to be a difficult task in past years. Poor countries are often reluctant to account for poverty due to corruption or the inability to do so because of ongoing conflicts. The World Bank reports that only 20 African countries conducted two or more population surveys on poverty from 2000 to 2010.

A new study from Stanford University hopes to improve poverty mapping by combining high-resolution satellite imagery with artificial intelligence.

According to a feature article published by online tech magazine Motherboard, Neal Jean, a Ph.D. engineering student at Stanford, has designed a machine learning algorithm that can predict poverty in Malawi, Nigeria, Rwanda, Tanzania, and Uganda.

Using satellite imagery to determine “nightlights” and levels of economic activity as a method of poverty mapping is nothing new. What’s different about the algorithm designed by Jean and his team is that it looks at daylight images of infrastructure, such as roads and metropolitan areas, which it then uses to identify nighttime patterns.

“Our basic approach involved a machine learning technique called ‘transfer learning,’ which is the idea that you can solve a hard problem – in our case, predicting poverty from satellite images – by trying to solve an easier one,” Jean said.

According to Motherboard, the algorithm may prove to be a very effective method of poverty mapping, especially given the cost of traditional household surveys and the lack of viable alternatives. Another advantage of the machine learning model is its transparency, as it doesn’t rely on private or protected information.

Jean told Motherboard that he hopes to make the technology open-source and cooperate with NGOs to put the algorithm to use. “If we could provide them with high-resolution poverty maps, they could overlay them on regions where operations already exist, and ultimately inform where they distribute funding,” he argued.

Jean’s machine learning algorithm is not the only artificial intelligence tool that is providing better data for poverty alleviation efforts. South African computer scientist Muthoni Masinde developed a solution that can forecast droughts with 98 percent accuracy, combining traditional knowledge with new technologies. In recognition of her achievements, she received a Distinguished Young Women Researcher award at the 2016 South African Women in Science Awards.

Technological advance has been the greatest impetus for poverty reduction throughout history, and artificial intelligence is the future of poverty mapping. It provides economists and scientists with better data in order to pinpoint and resolve problems that are holding developing countries back.

Call Records Can Predict Outbreaks of Deadly Dengue Fever

Dengue Fever
Dengue fever is a rapidly spreading viral disease in the developing world. Thankfully, though, a new method of analyzing cell phone call records to health clinics is proving successful at predicting the next outbreak locations of the disease.

This disease is mosquito-borne and results in flu-like symptoms that can persist until a fatality occurs, especially in children or others who do not have access to swift and proper medical care.

Dengue fever infects 390 million people worldwide every year, and many more are at risk. The illness is found mostly in tropical and sub-tropical climates and acts a leading cause of serious illness and death among children in Asian and Latin American countries.

In the United States, information on the spread of diseases is gathered by looking at road usage and other travel patterns. However, this kind of information proves often unavailable and unreliable in developing countries. Furthermore, dengue fever is the fastest-spreading mosquito-borne disease in the world, and many places are exposed to this disease for the first time and unprepared to effectively deal with such a health crisis.

According to a study published in Science Advances journal, researchers found that by studying cell phone call records in the Punjab region of Pakistan, they were able to pinpoint where dengue fever cases occurred and predict where they might occur next.

This new method looks at the patterns of calls to a local health hotline in conjunction with weather information. This combination provides real-time data of when and where the disease is likely to spread geographically.

The phone records are collected on a large-scale and anonymous basis to protect the personal privacy of the callers.

Dengue fever is often seen in areas of rapid urbanization, which commonly occurs in developing countries. This method of monitoring the disease is particularly useful in these developing countries because it is a low-cost method. Call pattern statistics provide an effective low-cost alternative in many nations that lack the resources to closely monitor the spread of disease.

Additionally, there is no specific globally-recognized treatment for dengue fever. Early detection has proven critical in helping those afflicted with the disease. Receiving medical care early on reduced mortality for this disease from more than 20 percent to less than one percent. Since call analysis can predict where outbreaks may occur in the future, it is an effective way to stop a disease that is particularly difficult to treat.

While the examination of call patterns does not currently account for international travel, which does play a role in the transmission of dengue fever, this transport avenue could certainly be in the future for statistical call analysis. Even the current iterations of this method provide important real-time data that can help reduce the spread of a dangerous disease, especially in developing countries.

Cell Phones in Africa Transform Banking

Cell Phones in AfricaIt is fair to say that cell phones have officially infiltrated Africa’s countries and completely transformed people’s methods of banking and agriculture. The increase of ease for both of these professions have factored into poverty reduction and the betterment of African lives. When it comes to banking, having access to cell phones in Africa is both useful and productive.

Cell Phones and Personal Finances

Cellular devices can easily be used to keep track of funds, to store funds in a safe location and to transfer funds. In 2007, Safaricom–Kenya’s largest mobile operator–and Vodafone developed a money transferring service called M-PESA. By 2012, M-PESA obtained 15 million Kenyan users–more than a third of the population. This newfound access to portable technology has also been extremely helpful in pulling people out of poverty-stricken situations.

For example, many users transfer their funds to individuals who are still trapped in severely impoverished rural areas. M-PESA provides a safer way to send someone money, so it cannot be stolen easily. The individuals who use M-PESA to store their funds also benefit. Their funds can be easily managed, which has caused an increasing amount of families to adopt this technology.

“One study found that in rural Kenyan households that adopted M-PESA, incomes increased by 5-30 percent,” according to The Economist. This proves that mobile phones help people climb the financial ladder to live better lives. There are also many African startup companies who have used M-PESA as a platform to initially pave their way in the business world.

Cell Phones and Agriculture

As previously stated, mobile phones have changed Africans’ way of agriculture as well. Farmers, the largest employers in Africa, now rely on their mobile phones for critical informational tips. “By serving as platforms for sharing weather information, market prices, and micro-insurance schemes, mobile phones are allowing Africa’s farmers to make better decisions, translating into higher-earning potentials,” according to CNN.

Farmers can figure out distant crop prices faster than ever before and effectively track the gestation of their cows. Therefore, the use of cell phones in Africa has allowed farmers to drastically improve their agricultural methods, which makes it easier to sustain their livelihood. The Borgen Project advocates for the world’s poor and knows how essential it is for developing countries to be able to sustain themselves. The use of cell phones in Africa have only helped in that regard, and it looks as if the technology is here to stay.

Cell Phones and Technological Advancements

Due to the technologically advanced world surrounding Africa, most Africans can enjoy the today’s “tech” nuances and pass over the dying technology of the past (such as landlines). In the year 2002, around one-in-10 Africans owned a mobile phone. In 2006, “There were 50 million new mobile subscribers… and in 2007 the total number of mobile subscriptions reached an estimated 200 million.” On average, that adds up to 20-plus active mobile phones for every 100 people.

The decline in cost and simplistic nature of mobile technology are the reasons why so many Africans have chosen to use portable tech. A report by the UNCTAD stated, “A decline in the cost of information and communication technology (ICT) has extended its use by the poor, who capitalize especially on information obtained by telephone to support livelihoods in agriculture and various small businesses.”

It is incredible to see how the proliferation of cell phones in Africa have so positively impacted the continent in such a short amount of time.

Improving Literacy Rates in Developing Countries with Phone Data

Phone Data

Literacy is one of the most significant contributing factors to eradicating poverty. Telenor, a Norwegian research group, believes it has found a way to measure literacy rates in developing countries using mobile phone data.

Currently, an estimated 750 million people around the world are unable to read and write. Two-thirds of these people are women, according to MIT Technology Review. UNESCO studied the effects of illiteracy in South American communities and found that illiteracy correlates to higher unemployment rates, poor health, exploitation and human rights abuse.

In order to address the growing concern of widespread illiteracy in developing countries, Telenor, led by Pål Sundsøy, developed a machine-learning algorithm to figure out which communities have the highest rates of illiteracy.

Using mobile phone data, Telenor’s algorithm evaluates a variety of factors to predict literacy rates in developing countries including the location of calls, number of incoming versus outgoing text messages and the diversity of social contacts.

When evaluating the probability of illiteracy, geographic location is one of the most deciding factors. Sundsøy believes that the algorithm is able to identify slum areas where economic development is low and illiteracy is high by analyzing where calls are placed.

Additionally, a higher quantity of outgoing messages and a lower number of incoming messages may also hint at illiteracy. Telenor’s model takes this information into consideration since people do not typically send texts to contacts who they know can’t read.

The diversity of an individual’s social network is also a helpful indicator of literacy since those who are illiterate are more likely to concentrate their efforts on communicating with a few people. The relationship between the diversity of social contacts and illiteracy is also supported by a strong three-way correlation between economic well-being, illiteracy and diversity of social contacts.

By identifying which communities are at risk for low literacy rates, Telenor’s mobile phone data algorithm can make literacy programs more effective in developing countries.

The National Literacy Programme in Namibia (NLPN) states that their main challenge to boosting literacy rates is limited funding for the program. Implementing Telenor’s algorithm would make a significant impact on programs like NLPN that have finite resources by helping organizations to identify and allocate resources to communities that have a higher concentration of illiterate people.

While regional and gender disparities continue to persist in current illiteracy data, the development of powerful resources like Telenor’s algorithm will help raise literacy rates in developing countries and make it easier for literacy programs to target those who at a greater disadvantage.

Drones Now Delivering Lifesaving Vaccines

DroneDeploying unmanned drones in low and middle-income countries could save money and increase vaccination rates, according to new research conducted by the Johns Hopkins Bloomberg School of Public Health and the Pittsburgh Supercomputing Center.

Many low- and middle-income countries struggle to deliver lifesaving vaccines to sick people who are fighting preventable diseases.

Bruce Y. Lee, director of operations at the International Vaccine Access Center at the Bloomberg School says “[We] make all these vaccines but they’re of no value if we don’t get them to the people who need them. So there is an urgent need to find new, cost-effective ways to do this.”

Currently, vaccines such as hepatitis B, tetanus, measles and rotavirus are typically transported by road through two to four storing sites before they reach clinics where the doses are finally administered to patients. The majority of vaccines require refrigeration until they are used or else they will spoil.

In addition, non-vaccine costs of routine immunization are expected to rise between 2010 and 2020, mostly derived from supply chain logistics.

In the meantime, unmanned drones have proliferated. They can traverse all land and topography, decrease labor costs and substitute the need for vehicle transportation. They have been heavily used for surveillance and in humanitarian aid delivery.

A study conducted at Johns Hopkins University found that utilizing drones to transport vaccines to their final destination could slightly increase the rate of immunization, immunizing 96 percent of the target population as compared to 94 percent using land-based transport. This simultaneously produced significant savings, eight cents for every dose administered (roughly 20 percent savings).

“Assuming the drones are reliable, are capable of making the necessary trips and have properly trained operators, they could be a less expensive means of transporting vaccines, especially in remote areas,” says Lee. He adds, “They could particularly be valuable for urgent orders.”

An initiative led by the United Parcel Service Foundation and Gavi, the Vaccine Alliance, has raised $800,000 grant to support the launch of a zip line drone project in Rwanda that will commence later this year. The government of Rwanda will use zip line drones to make 150 life-saving blood deliveries per day to 21 transfusing facilities in western part of the country.

According to Dr. Seth Berkley, CEO of Gavi, the Vaccine Alliance, “It is a totally different way to deliver vaccines to remote communities and we are extremely interested to learn if UAVs can provide a safe, effective way to make vaccines available for some of the hardest-to-reach children.”

The Rwanda drone network has been initially focused on delivering blood supplies, but plans to expand to include vaccines and treatments for HIV/AIDS, malaria and tuberculosis.

In rural Virginia, Bhutan and Papua New Guinea, drones are currently being tested for medical supply deliveries. UNICEF is also testing their viability of use in Malawi and in Tanzania.

Internet Traffic in Africa to Surge by 2020

Internet Traffic in AfricaAfrica will experience a boom in IP growth, with Internet traffic in Africa increasing six-fold by 2020, according to the Cisco Visual Networking Index.

Cisco’s forecast, which covers 2015 to 2020, has predicted that Africa’s IP traffic will grow at a rate of 41 percent, the fastest annual rate in the world. Fixed broadband speed is also expected to increase more than twofold, and average mobile connection speed will reach five megabits of data per second.

The projected rise in Internet traffic is partly a result of the spread of mobile personal devices across the continent.

According to a study by the Pew Research Center in 2015, cellphone ownership has surged in sub-Saharan Africa. Cellphones in South Africa and Nigeria have become as common as they are in the United States. People rely on their mobile phones for a variety of internet services, including browsing the web, mobile online banking and accessing social networking sites and political news.

Internet use through cellphones will likely continue to rise as 77 percent of networked devices in Africa in 2020 will be mobile-connected, according to Cisco’s forecast.

Advancements in the Internet of Things, which allow everyday devices to connect to the Internet, have also helped promote traffic growth.

Cisco said that applications, such as digital health monitors and energy smart meters, and machine-to-machine services are “creating new network requirements and incremental traffic increases.” Machine-to-machine modules will account for 22 percent of all network devices in Africa by 2020.

Yet, according to Mark Walker, the International Data Corporation’s associate vice president for Africa, the Middle East and Turkey, many countries in sub-Saharan Africa lag behind in technological capability and cannot afford Internet of Things applications.

In order for Cisco’s predictions to prove correct, less developed countries must continue to address affordability issues and develop infrastructure that will allow for greater use of the Internet, Walker told ITWeb Africa.

An increase in IP traffic will put the continent a step closer to achieving the United Nations’ goal of connecting more people in underdeveloped countries to the Internet by 2020. With more Internet availability, people who live in poverty can take advantage of enormous economic and social opportunities that the web offers.

Farmers in rural areas can use the Internet to plan for unpredictable weather and determine what type of crops to grow based on the prices of goods and commodities. People can also rely on the Internet for mobile banking, to educate children and to stay informed about news.

The increase in Internet traffic in Africa will also help the continent become more technologically advanced. Several countries, including South Africa, will rely on the increased Internet connectivity to complete a digital migration journey that involves the transition from broadcasting with analogue cables to more efficient digital television signals.

Poverty Stoplight Puts Poverty in the Spotlight

Poverty StoplightFundación Paraguaya has developed a tool to help families self-assess their poverty level and develop a personalized plan to improve their status.

Named the Poverty Stoplight, the initiative uses technology and various methodologies to create a custom poverty elimination plan, breaking down an overwhelming situation into smaller, more manageable problems and putting families in charge of their situation.

First, families take an online visual survey to determine their level of poverty. They are assessed on six different groups of poverty indicators: Income and Employment, Health and Environment, Housing and Infrastructure, Education and Culture, Organization and Participation and Interiority and Motivational.

Through a technology software developed by Hewlet Packard, each family receives 50 poverty indicators of red, yellow or green (red = extreme poverty, yellow = poverty, green = not living in poverty). For instance, fetching water from a contaminated river is an extreme poverty/red indicator, while having a water faucet in the house is a green/non-poverty indicator.

Trained members under Fundación Paraguaya work with each family based on their strengths and weaknesses in each category. The mentors make families aware of the tools they have within themselves that can be used to build a life out of poverty.

The Poverty Stoplight technology also provides information on neighbors who are not living in poverty and may be able to help them build homes and businesses.

The goal is to disrupt the typical cycles families in poverty go through, improving their status for their children and future generations.

The Paraguayan Government has been using the technology to refocus social workers on the main problems contributing to poverty.

A Google map overlay of Poverty Stoplight families highlights main poverty contributors, such as lack of proper vaccinations, clean water or proper sanitation. This overview allows social workers to provide the proper help to families in need and give them a jump start towards a better life.

Poverty Stoplight has had much success in helping impoverished families build a better life. In its first three years of operation, they have been able to help the welfare of around 18,000 families (92,000 people).

USAID has been a big contributor to the program, providing $500,000 in funding alongside other donors (who donated a total of $1 million). “This replicable project illustrates how relatively small amounts of foreign assistance can generate promising, tangible steps toward reducing poverty,” notes USAID.

Based upon a family’s motivation and the skills they have, a plan can be constructed to not only reduce their level of poverty but to eliminate the poverty cycle altogether. The customization of the project and effectiveness of the technology is what makes Poverty Stoplight as promising as it is.
