The global carbon credit trading schemes emanating from the Kyoto Protocol are now creating a multi-billion dollar market – the European carbon market was worth €14.6 billion in 2006 – and represents one of the fastest growing business opportunities in the world. Being green has finally come of age. Yet all the benefits of this are largely bypassing Africa despite more than 70 percent of the continent’s inhabitants earning a living off the land.
The World Agroforestry Centre – whose mission is to advance the science and practice of agroforestry to transform the lives and landscapes of the rural poor in developing countries – in partnership with Michigan State University has developed a method using satellite imagery and infrared sensing that measures carbon storage in African farmland. They have completed a pilot programme in western Kenya and are ready to encourage poor farmers to plant trees as soon as the European Union allows carbon credits under the Kyoto Protocol to be awarded for this kind of scheme. Further pilot projects will be rolled out in 2007 in partnership with CARE International and the WWF.
But European Union policies on carbon credits are holding back this significant opportunity to enhance African livelihoods. Europe’s Emissions Trading Scheme (ETS) is at present not willing to recognize the new method of verifying carbon storage in farmland. The ETS is the largest multi-country, multi-sector greenhouse gas emission trading scheme in the world. The issue of carbon storage, or carbon “sinks” as they are known, is very controversial in the world of Kyoto agreement implementation. Non-government organizations that advocate for forests and indigenous people have worked hard to exclude the use of forestry credits to offset fossil fuel burning, arguing that forestry offsets to date have been for big monoculture plantations of fast-growing eucalyptus or pine trees. It is claimed they are net carbon emitters over their lifetimes and also cause additional environmental and social problems.
But the World Agroforestry Centre’s approach is very different from a monoculture plantation. Their scheme is to help rural Africans to integrate more trees into their agricultural production systems, with benefits besides storing carbon. They argue that the right kinds of trees can increase the productivity and resilience of the land. Trees provide food, fuel, fertilizer, and medicine – medicinal trees are the main source of medication for 80 percent of Africa’s population.
Louis Verchon, the lead scientist for climate change at the World Agroforestry Centre, believes that if the EU would put in place a new scheme to credit farmers who capture carbon in their land, “millions of dollars in carbon credits could begin flowing to the world’s rural poor.” At present, Verchon says two-thirds of the carbon credit business is being captured by Asian countries who are mostly offering industrial solutions. “Africa has something to offer on this – it can’t compete with the likes of South Korea on industrial solutions, but it has plenty of land.”
In order to make the scheme work, two things will need to be improved: Africa’s institutional weakness and the paucity of qualified carbon credit verifiers. A network of verifiers would be required to inspect farm sites and make the calculations required to allocate carbon credits to poor farmers. At present, there are no qualified African-born verifiers in Africa according to Verchon.
The WAC are working with WWF and CARE to build up NGO capacity and start demonstration projects to prove it can work – two pilot projects are already up and running in Kenya. They are also automating much of the process by building a web portal.
Verchon says the WAC “are in it for the long-haul and we will see this grow over the next ten years.”

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.

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.
