Digital Mapping to put Slums on the Map
By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Mobile phones are more and more part of daily life in the South’s slums – even for the poorest people. One result is that it has now become possible to undertake digital mapping initiatives to truly find out who is where and what is actually going on.

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. How to improve their living conditions and raise their standard of living is the big challenge of the 21st century.

With just over five years until the 2015 deadline to meet the Millennium Development Goals (http://www.undp.org/mdg/), and the current economic downturn reversing some gains, any tool that can make development decisions more precise has to be a benefit.

People are now turning to the growing penetration of digital technologies into slums and poor areas to find solutions. With mobile phones available across much of the global South, and plans underway to expand access to broadband internet even in poorly served Africa, it is becoming possible to develop a digital picture of a slum area and map its needs and population.

Put to the right use, this powerful development tool can fast-track the delivery of aid and also better connect people to markets and government services.

In November, an NGO called Map Kibera (www.mapkibera.org) began work on an ambitious project to digitally map Africa’s largest slum, Kibera in Nairobi, Kenya .

The partners behind Map Kibera are Humanitarian OpenStreetMap, JumpStart International, WhereCampAfrica, the Social Development Network, Pamoja Trust, Hands on Kenya and others.

Estimates place the number of residents in Kibera at one million, but nobody really knows how many live there (UN-HABITAT). The slum is typical of such deprived areas, lacking in health and water resources and plagued by chaotic traffic and housing. Few fully grasp where everything is in the sprawl.

While data does exist on the slum, it is not shared or collated into one source. The Map Kibera project uses an open-source software programme, OpenStreetMap (http://www.openstreetmap.org/), to allow users to edit and add information as it is gathered. This information is then free to use by anybody wanting to grasp what is actually happening in Kibera: residents, NGOs, private companies and government officials.

This will literally put Kibera on Kenya’s map.

The mapping team started with 12 young people recruited in Kibera to start the work in November of this year. They will be trained and also receive support from the growing Nairobi technology community.

“The project will provide open-source data that will help illustrate the living conditions in Kibera,” said Map Kibera’s Mikel Maron. “Without basic knowledge of the geography of Kibera it is impossible to have an informed discussion on how to improve the lives of residents of Kibera.”

Workshops will communicate with local residents and show them the findings available from the map. Paper maps will be distributed to residents and then updated as new information comes in. It is critical local people are kept informed to build trust and avoid conflict. As can be seen from the Google Street Views (http://www.google.co.uk/help/maps/streetview/) controversy, nobody likes to be mapped without their permission or consent.

Like Kenya, Brazil has a long history of sprawling slums sprouting around its cities. Called favelas, they are complex places, with both rudimentary dwellings and elaborate mansions. Walking into a favela can be a journey through the dreams and aspirations of generations of people, often reflected in their dwellings. Favelas have many services, including hospitals, and there are restaurants and coffee shops. In short, while they are not in the official development plans, the favelas are vibrant economic entities and home to hundreds of thousands of people.

But since they are chaotic and undocumented by official maps, the economic and social development of the favelas is hindered as even basic services like mail delivery are difficult to provide.

An NGO called Rede Jovem (http://www.redejovem.org.br/) is deploying youths armed with GPS (global positioning system)-equipped (http://en.wikipedia.org/wiki/Global_Positioning_System) mobile phones to map the favelas of Rio de Janerio. To start with, they are mapping five favelas: Complexo do Alemão, Cidade de Deus, Morro do Pavão-Pavãozinho, Morro Santa Marta and Complexo da Maré.

“The main goal was to mark public interest spots on a map and show places like schools and institutions and hospitals and restaurants,” Natalia Santos, the executive coordinator for Rede Jovem, told MobileActive (www.mobileactive.org) . “We wanted to spread the news about what slums do have, so all the people can get to know that the slum is not just a place for violence and marginality and robbery.”

The mapping process works like this: the mappers physically travel around the favela and upload information on each, individual landmark (restaurants, roads etc.) as they go. They use Nokia N95s mobile phones that are connected to Google Maps (www.maps.google.com).

According to Santos, reporters enter the information on the map displayed on the phone, and they can video or photograph to add more detail. They are using Wikimapa (www.wikimapa.org.br), and Twitter (www.twitter.com) to log the information.

As Rede Jovem recruited young mappers, they discovered an interesting fact: the male reporters (aged between 17 and 25) were frightened to enter a favela with a mobile phone for fear of either being mugged or being stopped by the police. Because of this fact, all the mappers are young women.

They are ambitious for the future despite their funds running out in December. “We want everyone who has a cell phone with GPS to be a wikireporter,” said Santos .

How important it is to the favela residents to be recognised like this can’t be overstated. “I think they are very happy because they’re seeing that they exist,” said Santos. “And the mailman says that now he can deliver the mail.”

African Digital Laser Breakthrough Promises Future Innovation
By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

For decades many African countries have experienced low investment in research and development (R&D) and scientific innovation. One of the few nations to benefit from a sophisticated university network and research and development sector was South Africa. It still ranks top on the continent for funding R&D and its high number of scientific journals.

And it seems this support has paid off in a recent innovation. The world’s first digital laser designed and built in Africa has been developed by a team of physicists at the University of KwaZulu–Natal in South Africa (http://www.ukzn.ac.za/), as reported in the MIT Technology Review (http://www.technologyreview.com/).

This innovation joins a positive trend in Africa, where support to science, technology and R&D is rising – albeit from a very low base. In 2010 UNESCO – the United Nations Educational, Scientific and Cultural Organization – found Africa was reversing decades of neglect in research and development. African countries were increasing investment in science and technology after realizing it will accelerate their connection with the global economy and help create better-quality jobs to tackle poverty. The UNESCO Science Report found Burkina Faso, Kenya, Nigeria and South Africa had adopted laws to support biotechnology research, for example.

Since 2005, six new science academies have been established in Mauritius, Morocco, Mozambique, Sudan, Tanzania and Zimbabwe. This compares to nine established between 1902 and 2004.

The proportion of GDP (gross domestic product) devoted to R&D averages 0.3 per cent in Africa, according to UNESCO.

South Africa continues to lead in R&D spending, raising its investment from 0.73 per cent of GDP in 2001 to 0.94 per cent in 2006. The country is home to 46 per cent of Africa’s scientific publications compared to 11.4 per cent in Nigeria and 6.6 per cent in Kenya (UNESCO).

Experts say the digital laser developed in South Africa is a breakthrough that will open up ever-further innovations and business opportunities.

So, what is a digital laser and what is the innovation? A laser is short form for Light Amplification by Stimulated Emission of Radiation. It is a device that produces a concentrated light source. Unlike conventional light sources that emit a diffused, multispectral light, lasers allow for a monochromatic light beam to be concentrated on a small area. This can be used to cut an object precisely, or beamed over long distances without losing its strength.

Lasers can create immense light, heat and power at close range and are regularly used in surgery and medical diagnosis.

Conventional lasers require external devices to alter and bend the laser light beam. The digital laser allows the shape of the beam to be digitally altered internally at the touch of a computer keyboard and gives greater immediate control. This means a plethora of new shapes can be formed with the laser beam, and this can have many practical applications.

The digital laser augers in a new age of creativity with lasers and more spontaneity in how they are used. Rather than having to place a lens or mirror at the front of the casing to shape the laser beam, this innovation makes it possible to create any shape desired digitally by a computer. The research team has been able to create various complex shapes for the laser beams in experiments. One mooted use is to apply laser beams to manipulate microscopic objects – similar to the tractor beams seen in science fiction films such as “Star Trek”.

Few of us spend much time thinking about lasers, yet they are ubiquitous in the modern world and are found in many electronic products (https://en.wikipedia.org/wiki/List_of_laser_applications). They play a critical part in the modern world’s economy. Some common applications for lasers include laser light shows at music concerts, bar code readers at the grocery store, or laser pointers used during public presentations. Dentists also use them to speed the hardening of fillings.

Not to exploit lasers as a technology in the modern world is equivalent to bypassing the silicon micro-chip that sits inside personal computers, electronic devices and mobile phones.

Innovative Stoves to Help the Poor
By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Half of the world’s population cook with a fuel-burning stove, and this figure rises to 80 per cent of households in rural areas in developing countries. Typical fuels burned include wood, coal, crop leftovers and animal dung. The indoor pollution from smoke and carbon monoxide is a top health hazard in the developing world, ranking just behind dirty water, poor sanitation and malnutrition. The World Health Organization (WHO) estimates that 1.6 million people die each year as a result of toxic indoor air.

A landmark five-year study comparing Guatemalans cooking on open fires, to those using improved stoves, has brought more evidence forward of the damage done by indoor air pollution: “It’s been shown that children living in houses using open fires with solid fuels will have more pneumonia than children living in houses that are using cleaner fuels,” said Dr. Kirk R. Smith, an environmental health scientist at the University of California, Berkeley.

The research, combined with studies in Asia, suggests additional health problems from indoor air pollution, including higher frequency of cataracts, partial blindness, tuberculosis, low birth weights and high blood pressure. The researchers found that cleaner stoves had larger effects than reducing salt in the diet or lowering blood pressure in women, with the results published last July in Environmental Health Perspectives.

But Southern innovators are finding practical ways to curb pollution from indoor cooking and the burning of trash in slums.

In Yunnan Province, China, entrepreneur Hao Zheng Yi’s Yunnan Zhenghong Environmental Protection Co. has been selling clean-burning stoves to rural farmers. One fifth of rural China has no electricity (UN), and 80 per cent rural dwellers burn wood or straw in ovens for heating and cooking. This creates heavy indoor air pollution, damaging health.

The so-called Efficient Gasification Burning system combines traditional fuel and natural gas: a hybrid that helps low-income households to affordably use the stove and not pollute their indoor air.

The stoves are sold for a profit in Yunnan Province, and so far 50,000 have been sold. Because the ovens are sold for a profit, Zhenghong had to consult extensively with the farmers in the design phase to make sure the ovens meet their needs.

The result has been that Zhenghong ovens run for five to eight years using the same amount of wood and hay a conventional oven burns in one year.

Another source of air pollution is burning trash in slums. The lack of formal trash removal services in slums has two bad consequences: one is the pollution and poison from rotting rubbish leaching into the soil and water table; the other is ad-hoc burning of the trash to get rid of it, which pollutes the air with a toxic, acrid stench. In Nairobi’s Kibera slum – the second biggest in Africa – over 60 per cent of the city’s residents live in the slum, and are bypassed by garage collection services. Garbage is piled up along the muddy roads and paths, or hangs in the trees.

The Kenyan NGO Umande Trust, which specialises in water and sanitation projects, has developed a home-grown method to burn trash and avoid having to turn to very expensive and complicated incinerators from Europe. The sheer quantity of trash that needs to be burned in the slum means smaller solutions will not be able to handle the problem.

Its “community cooker” re-uses garbage from the community as fuel for a boiler and oven attached to it. The heat generated by burning the rubbish provides hot water and cooking facilities – and also jobs for unemployed youths who collect the rubbish and stock the incinerator. It was developed by a Kenyan architect, and it is hoped the “community cooker” will be taken up across Africa.

The community cooker’s inventor, Kenyan architect Jim Archer, took eight years to design and build it: “My thinking was how do we get rid of the rubbish and …how can we induce people to pick it up. Then I thought, well if we can convert it to heat on which people can cook…” he told Australia’s ABC News.

Similar industrial scale trash incinerators can cost between US $50 million to US $280 million (World Bank) – “…when applying waste incineration, the economic risk of project failure is high…”. The community cooker on the other hand, will sell for US $10,000.

The idea was to create an incinerator that was simple to use and repair: something that the commercially available, computer-controlled incinerators were not able to do. As the cooker gets up to speed, it will be able to burn 60 per cent of the slum’s trash.

Local youth go house-to-house collecting trash. They get money from the slum residents for this. Rubbish is then exchanged for cooking time or hot water for washing.

“The trash has started to help us a bit after the cooker came. There are fewer diseases like diarrhea and the environment has improved. … I think burning the rubbish will bring good health to this community,” said Patricia Ndunge, as she fried onions on the cooker.

And it looks like the community cooker has a future: Kenya’s largest supermarket, Nakumatt, has pledged to pay for 20 more slum cookers.

Cleaner Stoves To Reduce Global Warming
By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

The use of polluting fuel-burning stoves by half the world’s population – including 80 percent of rural households – is a documented contributor to a host of health problems. Poor households not only have to contend with the ill health effects of dirty water and poor sanitation, the fumes from burning dung, wood, coal or crop leftovers lead to the deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).

The polluting stoves have also been identified as major contributors to climate change. The soot from the fires produces black carbon, now considered a significant contributor to global warming. While carbon dioxide is the number one contributor to rising global temperatures, black carbon is second, causing 18 percent of warming.

Getting black carbon levels down is being seen as a relatively inexpensive way to reduce global warming while gaining another good: cleaner air for poor households. The soot only hangs around in the atmosphere for a few weeks while carbon dioxide lingers for years, so the impact can be seen quickly.

A flurry of initiatives across the South are now designing, developing and testing clean-burning stoves to tackle this problem. The number of initiatives is impressive (see list of clean-burning stove initiatives by country: http://www.bioenergylists.org/en/country), but the test will be who can develop stoves that poor households will actually use and find the right model to distribute them to half the world’s population.

In India, the Surya cookstove project is test marketing six prototypes of clean burning stoves with poor households. Developed by the Energy and Resources Institute (TERI) in New Delhi, the six stoves are still undergoing field testing. Initial criticisms from users have focused on the stoves’ durability and overly clinical appearance.

Cost will be critical to success no matter what the stove’s final design: “I’m sure they’d look nice, but I’d have to see them, to try them,” Chetram Jatrav in Kohlua, central India, told the New York Times. As her three children coughed, she continued that she would like a stove that “made less smoke and used less fuel” but she cannot afford one.

Envirofit India – founded in 2007 as a branch of the US-based Envirofit International – is at a more advanced stage, already selling clean-burning stoves across India and the Philippines. It claims to have already sold over 10,000 stoves to poor households.

They have developed high-quality stoves in four models: the B-110 Value Single Pot (a simple stove for one pot), S-2100 Deluxe Single Pot (a sturdier design), S-4150 Deluxe Double Pot (two burning surfaces), S-4150 Deluxe Double Pot with Chimney. They have been designed to be visually appealing for households – in tasteful colours like blue and green – and using high quality engineering for durability.

They have been tested by engineers at the Colorado State University’s Engines and Energy Conversion Laboratory and are certified for design and environmental standards.

The stoves are on sale in 1,000 villages in Karnataka, Tamil Nadu, Kerala, and Andhra Pradesh. The stoves have already successfully undergone pilot testing in Chitradurga and Dharmapuri. The manufacturer uses a network of dealers, distributors, village entrepreneurs and not-for-profit organizations to make the stoves commercially available for purchase. They hope to have 1,500 dealer outlets by the end of 2009.

“Envirofit clean cookstoves have received an overwhelming reception in India,” said Ron Bills, chairman and chief executive officer at Envirofit. “Our cookstoves are not only meticulously engineered to reduce toxic emissions and fuel use; they are also aesthetically designed and durable. Envirofit takes great pride in offering high-quality, affordable products to typically underserved global markets.”

But once again price comes up as a major issue: Envirofit’s stoves are designed to last five years, and thus they cost more than other stoves for sale in India. An Envirofit stove costs between 500 rupees (US $10) to 2,000 rupees (US $40): existing stoves sell for between 250 rupees (US $5) and 1,000 rupees (US $20), and last a year at most.

As one blogger complained: “The envirofit stoves … are way beyond the capacity of the low income households who form 65% of the Indian population. Only the 10% of the middle to higher income segment can go for them… perhaps the price can be brought down by reducing the showy part of the stove to help the poorest.”

Envirofit is part of the Shell Foundation’s Breathing Space program, established to tackle indoor air pollution from cooking fires in homes and hopes to sell and place 10 million clean-burning stoves in five countries over the next five years.
