The Internet has revolutionized retail sales in many developed countries – and nowhere more so than for booksellers. The ability to offer an almost unlimited supply of books through a website is revolutionizing the way people shop and giving life to books long out of print or by unknown authors.
Kenya has recently gained a reputation for doing things differently in Africa and making great strides when it comes to using information technologies. And the next development in this story is the launch of a Kenyan online book shop modelled on the successful U.S. online bookseller Amazon (amazon.com).
A book boom is well underway across the global South. Literary festivals continue to expand, from Colombia in South America to India to Nigeria in West Africa, and so do sales of books, newspapers and magazines. While the publishing industries in developed countries despair at the impact of digital media on their profits, in the global South, rising prosperity and literacy are fuelling greater interest in reading and a growing print publishing industry. For example, India is experiencing 15-per-cent-a-year growth for its publishing industry, which is valued at nearly US $2 billion (Frankfurt Book Fair).
Kenya’s Text Book Centre (TCB) (textbookcentre.com), considered one of the country’s most reputable booksellers, has launched its own online book selling portal and its “eBook web store”. It is targeting readers across East Africa and sells books in 14 categories. Being Kenyan, it is taking an innovative approach that recognizes the large numbers of people who are doing all their transactions over mobile phones. The book portal allows customers to make purchases with their mobile phones using mobile money. This system uses the Kopo Kopo (kopokopo.com) software platform, which allows small and medium sized businesses to accept mobile phone payments.
Kopo Kopo was first developed in Sierra Leone in 2011, before being further prototyped in Kenya. Kopo Kopo wanted to develop an effective mobile platform to help small and medium sized businesses to better interact with their customers. The Kopo Kopo service was officially launched in February 2012 and is partnered with Safaricom, using its M-PESA Buy Goods service. It is being currently used by hundreds of businesses, from “salons to restaurants to office supply stores”, according to Kopo Kopo’s website.
As an added benefit, the Kenyan online book platform is joined by a new marketplace for thousands of African ebooks. This part of the service is called eKitabu (ekitabu.com).
EKitabu will be a big boost to the continent’s authors and also open up new opportunities for budding authors who previously would have struggled to get published and distribute their work. If the ebook web store follows the dynamic of online booksellers in more developed markets, then this ability to gain exposure for author’s work and find an audience could also attract bigger publishers and spark interest in international book deals for formerly obscure writers.
The Text Book Centre was founded in 1964 by two Indian business partners in Kenya, Mr. SV Shah and Mr. MJ Rughani, and is now considered the leading bookstore in Kenya, specializing in leisure and educational books, according to its website.
Headquartered in Nairobi’s central business district, it focuses on providing books for the educational sector and strives to be “East Africa’s leading leisure and educational bookstore and office support resource centre”. It also supplies to customers in Uganda, Sudan, Somalia, Malawi, Zanzibar and Tanzania.

Finding ways to generate low-cost or free light has captured the imagination of innovators across the global South. The desire for light is strong: Light gives an immediate boost to income-making opportunities and quality of life when the sun goes down or in dark homes with few windows.
More than 1.7 billion people around the world have no domestic electricity supply, of whom more than 500 million live in sub-Saharan Africa (World Bank). Without a source of electricity, it is difficult to use conventional technology to switch the lights on.
While it is possible to run lights using batteries or diesel generators, these are expensive options that are not possible for many poor people. The more of a slim income that is spent on light, heat or cooking fuel, the less there is left for better-quality food, clothing, transport or education and skills development.
Low-cost light is great, but free light is even better – and one Brazilian solution is offering this.
Brazilian innovator and mechanic Alfredo Moser has taken the common plastic water bottle and created a low-cost lighting solution for dark spaces. Often makeshift homes lack decent lighting or a good design that lets the light in during the day. This means it may be a bright, sunny day outside, but inside the home or workplace, it is very dark and reading or working is difficult.
Moser came upon the idea during regular blackouts in his home city of Uberaba (http://www.uberaba.mg.gov.br/portal/principal) in southern Brazil during 2002. During the blackouts, only factories were able to get electricity, leaving the rest of the population in the dark.
The “Moser Light” involves taking plastic bottles, which are usually just thrown away or recycled, and filling them with water and bleach to draw on a basic physical phenomenon: the refraction of sunlight when it passes through a water-based medium.
It is a simple idea: Holes are drilled in the ceiling of a room and the bottles placed in the holes. The liquid-filled bottle amplifies the existing sunlight (or even moonlight) and projects it into the dark room. This turns the plastic bottle into a very bright lightbulb that does not require any electricity.
Moser uses a solution of two capfuls of bleach added to the water to prevent anything growing in the water such as algae because of the exposure to sunlight.
“The cleaner the bottle, the better,” he said.
Polyester resin is used to seal the hole around the plastic bottle and make it watertight from rain.
Moser claims his bottle innovation can produce between 40 and 60 watts of light.
Moser uses recycled plastic bottles, so the carbon footprint is minimal compared to the manufacture of one incandescent bulb, which takes 0.45 kilograms of CO2 (UN). Running a 50 Watt incandescent light bulb for 14 hours a day for a year, around the same light as produced by the bottle bulb, produces a carbon footprint of nearly 200 kilograms of CO2.
“There was one man who installed the lights and within a month he had saved enough to pay for the essential things for his child, who was about to be born. Can you imagine?” Moser told the BBC.
The plan is to try and get as many as a million homes fitted with the lighting system by the end of 2013.
In many poor areas, it is common to live in makeshift or rudimentary dwellings. These are often built to crude designs and, in order to keep costs down and boost security, will have few or no windows. These dwellings will consequently be very dark inside, even on the brightest days. This leaves people having to turn to a source of artificial light if they want to do something indoors like read or work. And this costs money. Be it electricity from a mains, or battery-powered lamps or gas-powered lanterns, the cost will eat into a person’s tight income. This is where Moser’s simple solution saves the day and saves pennies: it is free light once the bottle lamp system is installed.
Placing the bottle lights in the ceiling transforms the ceiling into something akin to the night sky, with many points of light shining down into the room like stars. It also means the occupant of the room does not just have to strain to see with the use of a single light but now has many lights illuminating the room from all angles.
“It’s a divine light,” Moser told the BBC World Service. “God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can’t get an electric shock from it, and it doesn’t cost a penny.”
It has not been a road to riches for Moser. He has made some money installing the system in a local supermarket and nearby homes, and he has inspired a charity to install the lighting system and to train people to do the installation and make an income from it.
The MyShelter Foundation in the Philippines was inspired by Moser’s invention and has installed the system in some 140,000 homes there, the BBC reported.
“We want him to know that there are a great number of people who admire what he is doing,” MyShelter Executive Director Illac Angelo Diaz said of Moser.
Using bottle bulbs instead of electricity or generators means families can save US $6 per month, according to Diaz (CNN). The Philippines is reported to have the most expensive electricity in Asia and slum homes usually do not have electricity.
It is estimated 15 other countries also have homes using the Moser system. The MyShelter Foundation believes 1 million homes worldwide have used the Moser system as of 2013.
Liter of Light (http://aliteroflight.org), run by the MyShelter Foundation, offers instructions on how to install the lighting system on its website.

As the population around the world’s cities grows, and slums grow larger and more prevalent, the urgent need for affordable and decent housing becomes more pressing. The world’s megacities – like Buenos Aires, Argentina, where more than 13 million live in the metropolitan region – have to find a way to provide housing that is both cheap and does the minimum possible amount of harm to the environment.
About one-third of the world’s urban dwellers live in slums, and the United Nations estimates that the number of people living in such conditions will double by 2030 as a result of rapid urbanization in developing countries. Latin America is already the most urbanized region in the developing world.
“Throughout Latin America you have economies that are growing and doing well, but the way the economies are growing is actually generating more shanty towns,” said Erik Vittrup, senior adviser on Latin America and the Caribbean for the U.N. Human Settlements Program. “It’s a growth that is just generating wealth for those who (already) have it.”
How well people dwell is integral to their mental and physical health. Most squatters and slum dwellers live in makeshift homes made from whatever they can get their hands on. These dwellings are usually unsafe and vulnerable to fire, floods, and earthquakes.
But across the South, initiatives are proving it is possible to build good quality homes for the poor while avoiding burdening them with debt. Pioneering ways are being developed for the poor to build their own high-quality houses using recycled materials and environmentally friendly products.
In Colombia , Alejandro Salazar, a chemical engineer, professor at the Universidad del Valle (http://www.univalle.edu.co/english/) and innovator running several companies pioneering new building technologies using recycled waste, is building high-quality, inexpensive houses for the poor. By combining free building materials recovered from waste, a government grant and the voluntary labour of the homeowners, Salazar’s company is able to build homes for the poor that don’t leave them with ongoing bank debt from mortgages.
Based in Cali, Colombia (http://gosouthamerica.about.com/od/cali/p/Cali.htm), his companies Ecoingenieria (product and material research and development), Ecomat SA (production of eco-materials using industrial waste and construction rubble), Constructora Paez, (social housing construction using eco-products) and Wassh SA (environmental management and transformation of dangerous solid waste into non-dangerous materials), are focused on pioneering new technologies for housing.
“Our company uses two basic technologies,” said Salazar. “The production of eco-materials from solid waste and demolition waste, and the implementation of an agile building system, which does not require skilled labour and is hand-transportable. All the pieces are produced in a prefabrication plant that uses the eco-materials.”
Salazar has found a way to provide homes quicker than existing NGOs – Popular Housing Organizations (OPV), as they are called – established to address homelessness in Colombia. The homeless poor are caught in a Catch-22: they need to have a formal job to receive homebuilding assistance from the government, and they usually can not save up enough money for a down payment on the home.
Salazar’s solution is to take the maximum grant given by the central government, which is US $4,730, and combine it with the recycled building materials and homeowners’ own labour. He says this allows a house to be built for roughly half the price of a similarly sized one that uses conventional materials: the eco-materials house costs around US $ 6,590, compared to US $12,000 using conventional materials. Land is often either donated by the municipality or the family already owns it. And in Salazar’s experience, the whole family chips in with the building: husbands, sons, brothers, fathers, wives.
The training takes just three days on eco-materials and a day in construction techniques for house building.
“To date, we have built with this method 306 houses,” said Salazar. “For the coming year, we expect to deliver around 500 houses or more. To build a house, after acquiring the land, we need three people working eight hours a day to build it in four weeks – all under the supervision of a workforce teacher and the supervision of an engineer or architect.
“The houses are designed by architects with the participation of the community or families. They do some workshops and the design conforms to their vision and expectation. In Colombia, there is an earthquake resistance code which is binding in law and provides detailed specifications of the materials, foundations, structure and roof.”
The pre-fabricated building materials are made from recovered waste from a wide variety of sources: ceramic red brick, coarse ash and fly ash, slag from steel, copper slag, porcelain insulators used for electrical power lines, nickel slag, sludge from sugar and alcohol plants and water treatment plants.
“The raw materials we use are industrial solid waste and demolition waste. It costs the industry a lot to throw away this waste,” Salazar said.
He said the biggest obstacle to the new homes is psychological: many people initially “tend to reject at first-hand the technology.”
“When visiting the factory and then visiting the homes – or model homes – they then compare it with a traditional house, and realize that the best eco-homes when finished meet the standards of Colombian earthquake resistance and are also cheaper,” he said.
Compared to using conventional building materials, the eco-materials reduce the cost of a new home. And the company still makes a profit from it!
In Paraguay, Elsa Zaldivaris using recycled plastic, cotton netting, corn husks, and loofah sponges (http://en.wikipedia.org/wiki/Luffa) to make cheap, lightweight construction panels for housing. This has a double benefit: it makes for cheap housing and it is good for the environment.
“That’s very important in Paraguay,” said Zaldivar, “because we’ve already reduced our original forest to less than 10 percent of the national territory.”
Zaldivar got her experience working with people in the impoverished area of Caaguazú, where in the past she helped with the building of toilets and making stoves. She found that involving local people in this work made a huge difference: “They told me: ‘Now we feel like we’re people with dignity.’”
She encourages local women to grow loofah – a plant that once flourished but was being ignored. While the fruit is edible she was more interested in the crusty sponge that is left over when the plant is dried. The women started a cooperative selling loofah sponges, mats and slippers. But there was a lot of waste in the process, with a third not suitable for export. She then came up with the idea to use the loofahs for wall and roof panels for cheap housing.
Along with industrial engineer Pedro Padros, she developed a way to combine loofah with plastic waste. Padros invented a machine to melt the recycled plastic and mix the molten plastic with loofah, vegetable fibres and chopped corn husks. It has produced a building panel that is lighter and easier to move around than lumber or brick. With a grant from the Inter-American Development Bank, design improvements have been made and the cost-per-panel brought down from US $6 per square meter. It is now competitive with the cost of wood panels. The great thing about the panels is that they can be recycled again when they wear out, completing the cycle.
“To have a decent home liberates people,” said Zaldivar.

For many years it was a given that the world’s problem was not a lack of food, but that it was unfairly shared. But as the switch to biofuels gathers pace, farmland is being diverted away from growing food for people, to food for fuel. On top of this, growing prosperity in many countries in the South has boosted demand for better quality food, including grain-devouring meat diets – it takes 10 kilograms of grain to get one kilogram of meat from a cow. The crisis has deeply alarmed the UN’s World Food Programme and the World Bank. In the economic battle for food, the poor are the most vulnerable.
So-called agflation (agricultural inflation) has seen spiraling food prices, which in turn are causing food shortages, hunger and malnutrition around the world. For example, rice in Thailand has jumped from US $400 per 100 kilograms in January, to US $760. World grain stocks are at their lowest level in four decades.
But where can new sources of food be found? And what would be a more efficient use of the world’s resources to feed the growing population? One answer, surprisingly, is insects.
In February this year the UN’s Food and Agriculture Organization held a conference in Chiang Mai, Thailand to devour the dietary value of insects as food and discuss how to harvest more of them. The working group of three dozen scientists from 15 countries probed the role of edible forest insects in food security. They explored insect protein as a contributor to better nutrition, the economics of collecting edible forest insects, methods of harvesting, processing and marketing edible forest insects, and ways of promoting insect eating with snacks, dishes, condiments — even recipes.
The range of insects that can be tapped for food is huge: beetles, ants, bees, crickets, silk worms, moths, termites, larvae, spiders, tarantulas and scorpions. More than 1,400 insect species are eaten in 90 countries in the South. Known as entomophagy, insect eating is a growing industry. Entrepreneurs in the South are making insects both palatable and marketable – and in turn profitable. These innovations are adding another income source for farmers and the poor, and supplying another weapon to the battle for global food security.
Insects have one big advantage as a food source: they are efficient converters of food into protein. Based on the weight of the food required to feed them, crickets are twice as efficient as pigs and broiler chicks, four times more efficient than sheep and six times more efficient than cows. They breed at a far faster rate, and they contain essential amino acids. They are seen as an ecologically friendly alternative to traditional animal rearing.
There are downsides to insects, however. In areas where there is heavy pesticide spraying on crops, insects can retain the pesticides in their bodies. Another key issue is sustainability: insect harvesting in some places has driven species to extinction. Then there is revulsion for some: in Western diets, there is an aversion to entomophagy, although most Westerners are happy to eat honey.
Revulsion at eating of insects is misguided. Most grains and preserved food products contain large quantities of insects or insect fragments mixed in. For example, rice usually contains rice weevil larvae – and they can be an important source of vitamins.
In Africa, 250 edible insects are eaten, from termites to grasshoppers, and have helped people through many food emergencies on the continent.
In South Africa — where edible insects are a multimillion dollar industry — Botswana and Zimbabwe, the local taste for mopane worms is being harvested for profits and nutrition. The worms, which inhabit mopane tress, require only three kilograms of feed (mopane leaves) to produce one kilogram of worms. At a rural factory in Limpopo province, South Africa, the community of Giyani is working to launch a wide range of products made from mopane worms – sustainably harvesting this larvae of the mopane emperor moth, gonimbrasia belina.
The Greater Giyani Natural Resources Development Programme in partnership with scientists at the University of Pretoria, is developing mopane worm products, including essential oils. The worms are usually par-boiled and then sun dried by locals. But at the Dzumeri Mopane Manufacturing Centre, the worms are processed and made ready for market. The local people are being trained in how to harvest the worms hygienically, and how to sort and grade the worms. The products will include deep-fried snacks and seasoning spices. It is critical the worms are harvested in a sustainable way, because in some parts of southern Africa, they have been driven to extinction.
Johnathon Mndawe, the programme manager, is organizing women and youth into co-ops to make viable commercial enterprises. “We expect the product to hit supermarket shelves in 2009,” said Morewane Mampuru, coordinator for the Centre for Scientific and Industrial Research, another partner.
One of the women, mother of four Mthavini Khosa, is excited: “For many years, we have been harvesting worms for food. We are excited because we will soon be doing it to make money.”
In Thailand, insect harvesting is a well-established business. Thais eat more than 150 insects, including crickets, silk worms and dung beetles. Canned crickets are regularly sold in supermarkets. Bugs are easily bought in the markets of Bangkok.
Online vendor Thailand Unique, based in Udon Thani, sells and markets a wide range of edible insects. They include edible scorpions, preserved giant water bugs, roasted grasshoppers, edible big crickets, bamboo worms, crushed giant bug paste, and introducing this year, Bug Snackz and Scorpion Thai Green Curry. There is even a ‘Bug Sample Pack’, containing a mix of seven edible insects and arachnids, all slow roasted for easy snacking.
Another important centre for insect harvesting is Latin America. In Venezuala, the Pemon Indians eat fire ants during the rainy season.
In Colombia, so-called “fatass ant” or “hormiga culona” is eaten like popcorn in movie theatres. Some believe it is a defence against cancer, or a natural aphrodisiac. Eating the ants or culona, has been happening right back to the ancient Guane Indians.
In Santander province, farmers are exporting the ants for sale, some being dipped in Belgian chocolate and sold as a luxury food in London’s Harrods and Fortnum and Mason department stores. The abundant ant population brings in US $11 a pound (kilogram conversion) for the farmers, a doubling in price since 2000.
Farmers in the artist colony of Barichara harvest the ants – though concerns have been raised that they have been over-harvesting the population. Restaurants in the area offer ant-based spreads for bread and an ant-flavored lamb sauce.
“It’s an age-old dilemma for the farmer — should I kill it or eat it?” said Andres Santamaria to CBS News, who was given a $40,000 grant from Santander’s government to develop an environmentally sustainable, export-oriented programme for breeding the ants.
In Tijuana, Mexico, ancient Aztec, pre-Colombian insect meals are on offer at this restaurant, joining a global trend. Cien Anios (“100 Years”), specialises in pre-Colombian, Aztec insect recipes. It is proof there is money in preparing insects for food. Typical dishes include garlicky ant eggs and cactus worms in butter.
