  • Lagos Traffic Crunch Gets a New Solution

    Lagos Traffic Crunch Gets a New Solution

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Around the world, traffic congestion is often accepted as the price paid for rapid development and a dynamic economy. But as anyone who lives in a large city knows, there comes a tipping point where the congestion begins to harm economic activity by wasting people’s time in lengthy and aggravating commuting, and leaving commuters frazzled and burned out by the whole experience.

    According to the World Business Council for Sustainable Development, 95 per cent of congestion growth in the coming years will be in developing countries. Even in developed countries like the United States, in 2000, the average driver experienced 27 hours of delays (up seven hours from 1980) (MIT Press). This balloons to 136 hours in Los Angeles.

    Developing countries are seeing vehicle numbers rise by between 10 and 30 per cent per year (World Bank). In economic hotspots, growth is even faster.

    Lagos, Nigeria, the throbbing business hub of West Africa’s most populous nation, has a network of over 2,700 km of roads with a vehicle density of 740 vehicles per kilometre (E.I. Bello). All those cars consume over 85 per cent of the petroleum products imported into the country – a costly expense for a country that actually imports oil. All this driving is necessary because the city has no rail or sea mass transit system and all movements of people and goods are by road.

    Nigeria suffers from the irony of being a country that makes 95 per cent of its export earnings and 80 per cent of its revenue from oil, yet has to import most of its fuel because its refineries are constantly breaking down.

    The overwhelming majority of mega-cities are now located in developing countries, including sprawling conurbations such as São Paulo, Brazil (18.8 million inhabitants in 2007), Delhi, India (15.9 million), and Manila, Philippines (11.1 million). By 2015 Lagos will have 12.8 million inhabitants and by 2025, it is estimated it will have 16.8 million citizens.

    That will be a lot of cars and frustrated people trying to get around.

    One project trying to alleviate the pain of a daily commute in the city is called Traffic (Traffic.com.ng). The computer application, or ‘app’, has a live feed of traffic on its homepage, collecting information from a wide variety of sources: the web, mobile phones and SMS (short message service) text messages sent in by mobile telephone. The service is also looking to extract information from microblogging site Twitter (twitter.com).

    The service says it aims to “reduce stress on Lagos road by providing up-to-the-minute traffic status in the state.”

    It uses the powerful concept of ‘crowdsourcing’, in which a large group of people contributes to solve a problem by combining the technological power of mobile phones and the Internet. These two technologies mean it is possible to solve problems in real time and draw on a very large group of people spread out over a wide geographical area.

    So, how does it work? A user can go to the homepage and click “View Traffic Report From” and see live data streaming in. If the user wants to see traffic conditions in a particular area, they type in the road and area in a box on the page and click to see the report.

    Those who are stuck in a traffic jam and want to alert others can send an SMS message with the keywords to 07026702053.

    The Traffic app came under scrutiny by the anonymous blogger Cherchez la Curl, whose blog is about “celebrating African women and natural hair”: “It’s no Einstein-worthy revelation to say that solving Lagos’ traffic problem (and, more generally, improving Nigeria’s poor transportation network) is one of the keys to sustaining growth and economic development in Nigeria,” the blog said.

    The blog’s author found the service was still in its early days: “While the idea is a fantastic application of modern technology to developing Africa, the only problem I see is that it seems like no-one is sending through traffic alerts! On a recent visit to the site, the alert stream was empty of alerts save for a few tweets. It’s a shame as this service would be extremely handy as a counterpoint/band-aid whilst government sorts out the root cause of the traffic.”

    It sounds like it is still early days for the Traffic app and Lagos residents will be its harshest critics.

  • Free Magazine Boosts Income for Rickshaw Drivers

    Free Magazine Boosts Income for Rickshaw Drivers

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    In the bustling, congested cities of Asia, rickshaws and auto-rickshaws are common forms of transport. Smaller, cheaper and more nimble than cars, they play a key role in the transit infrastructure, helping to get people to work and to get around.

    According to a report by the World Resources Institute (wri.org) and EMBARQ – a global network of experts on sustainable transport solutions – India’s auto rickshaws are “an increasingly important part of urban transport in cities.”

    The report estimates the number of auto rickshaws at between 15,000 and 30,000 in medium-sized cities and over 50,000 in large cities. The report found they make up between 10 and 20 per cent of daily motorized road transport trips for people in Bangalore, Mumbai, Pune and Rajkot.

    And it’s not just the economic role played in transporting people: auto rickshaws are made in India and their production there doubled between 2003 and 2010, making them a source of manufacturing jobs too.

    As India’s cities continue to grow – estimates forecast urban populations surging from 340 million in 2008 to 590 million by 2030 – auto rickshaws could have a bright future as they remain an affordable and safe transport solution.

    The monthly magazine Meter Down (http://meterdown.co.in/) – launched in 2010 – is targeting the large captive audience of Mumbai’s rickshaw passengers with news and advertising. It is modelled on the familiar free newspapers found in cities around the world. Usually, these newspapers are distributed at subway and metro stations or in metal boxes at bus stops. Meter Down takes a different twist on this concept, distributing the publication directly to rickshaw passengers.

    Mumbai is a crowded and very busy Indian city with an estimated 14 million people. Many residents spend a lot of time commuting – and a lot of time stuck in traffic jams. They need something to occupy them and to keep them informed about the news. This also presents a significant opportunity for businesses to communicate messages and advertising products and services.

    Founded by three university graduates, Meter Down is trying to reach young professionals with a bit of money who can afford to ride to work in auto rickshaws.

    It is distributed through 7,000 auto rickshaws in Mumbai, according to The Guardian newspaper, and is also being distributed in Pune and Ahmedabad.

    The clever bit is the incentive for the drivers to carry the magazine: they receive 35 to 40 per cent of the profit from advertising sales.

    This is added to the 400 to 500 rupees they make in a normal shift, according to the Mumbai Autorickshawmen’s Union.

    But isn’t it a challenge to read a printed publication while bouncing along the road? The publishers came up with a solution: no story is to be longer than 300 words and the magazine has many large-size photographs to make it visually appealing and easy on the eye. Then there is the issue of passengers leaving with a copy of the magazine, denying the next passenger their read. The solution they came up for this is to tie the magazine to the rickshaw.

    One of the biggest problems for any new start-up publication is how to scale up and reach more readers. Meter Down cleverly has the mechanism to scale built into its business model: “The market for this is as big as the total number of auto-rickshaws in each city,” Dedhia told The Guardian. “We have successfully scaled the model and tweak it as per different specific needs. Since auto-rickshaws are present in every part of the country, we can expand the network everywhere.”

    Meter Down’s founders estimate that each rickshaw makes 90 to 95 trips every day. They have calculated this leads to a potential readership of 600,000 people. To increase revenue sources, the magazine also sells advertising space on the back and inside of the rickshaws.

    For people in wealthier countries, rickshaws may seem like a rough way to get to work, but they are actually, for Indians, the more expensive option. A three-mile ride in Mumbai costs 68 rupees (US $1.27), according to The Guardian, which is 10 times the cost of a second-class train ticket.

    For Meter Down, this means targeting the magazine and the ads at a market of readers with money and a willingness to buy products and services. It looks like things could be on the up for Meter Down!

  • Battery Business Brings Tanzanians Cheap Electricity

    Battery Business Brings Tanzanians Cheap Electricity

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Access to electricity is critical for making substantial development gains. With steady supplies of electricity, it is possible to read and study at night, to run modern appliances, to better use the latest information technologies and to work using time- and labour-saving devices. A home with electricity literally switches the light on modern life and gives a family huge advantages compared to those without electricity.

    But there are two potential obstacles to providing electricity for the poor: one is just getting access to a steady supply; the other is paying for it.

    In Africa, much of the population suffers from an electricity famine. The situation is worse than on any other continent: the proportion of people in Africa still without electricity is higher – and the rate of urban electrification is lower – than anywhere else. Four out of five rural residents in Africa live without electricity. The rate of rural electrification is also lower than on any other continent and the proportion of Africans who depend on inefficient traditional energy sources is higher than elsewhere (Desertec-Africa).

    EGG-energy (http://egg-energy.com) is a Tanzanian company using an innovative business model to bring affordable electricity to rural communities.

    Its co-founder, Jamie Yang, said Tanzania has a huge potential market for offgrid energy services. About 85 per cent of the population lacks access to electricity, a figure that rises to 98 per cent of the rural population.

    EGG-energy says it is “dedicated to helping low-income consumers in sub-Saharan Africa gain access to clean, affordable energy, using a unique strategy based around portable rechargeable batteries.” The company has eight full-time staff based in their Makumbusho office, 6 kilometres north of Dar es Salaam, the capital.

    It calls its system the “portable grid,” and it works like this: customers have a power system installed in their home that runs on brick-sized, re-chargeable batteries. The batteries are re-charged at a central charging station using power from the Tanzanian power grid, and sent to local distribution centres where customers can pick them up. Customers rent the batteries for a subscription fee, and they last about five nights in a home. When the battery is empty, the customer returns it, swaps for a fresh battery and pays a small swapping fee.

    It is a brilliant solution to the problem of getting power from the main Tanzanian power grid to people’s homes. According to EGG-energy, most Tanzanians live within 5 kilometres from a power grid line. Yet the majority of the population lack access to electricity.

    “After researching the energy situation in Tanzania and other countries with similar electricity access problems, it became clear that one of the primary problems was a lack of last-mile distribution,” explained Yang. “The only way to get power from the source into homes and businesses were power lines, and for the vast majority of rural Tanzanians, this was very much out of reach.

    We saw situations in which power lines would pass right over large populations that were still using kerosene for lighting. We also saw that distributed generation like solar was finding only very limited markets because there was no share or sell power from that source without an affordable way to distribute the electricity.”

    While EGG-energy is based in Tanzania, it hopes hope to expand across the developing world.

    In order to develop an effective distribution network, EGG-energy partners with local store owners and delivery businesses to help with distributing the batteries. The batteries are based on those used in the airline industry and are light enough to be held in one hand.

    Yang believes marketing is critical to the success of the technology.

    “Don’t underestimate the cost of sales, marketing, and distribution,” he said.

    “Many companies focus on the technology and in lowering the cost of the technology, while not paying enough attention to the gaps in the distribution channels.

    “We have a sales team that communicates what we do through a variety of methods, including door-to-door sales, road shows and village meetings. We also make contact with the local political leaders and offer referral awards to our existing customers. Potential customers come to our charging stations to purchase the system and to connect to EGG.”

    When a customer signs up with EGG-energy, a technician is dispatched to their home to make sure the electricity system is sound and effective. The company also sells energy-efficient lights, radios and mobile phone chargers to complement the electricity system. It’s a wise business model, since having a steady and reliable supply of electricity is a great motivator for customers to purchase other electric-powered appliances.

    “We have technicians that have received vocational training through the Tanzanian system and technicians that we train ourselves,” Yang said. “We have very standardized electricity installations that are easy to teach, and have more experienced technicians that we rely on for troubleshooting and support.”

    EGG-energy also makes the claim it can reduce a household’s energy expenses by 50 per cent as they make the switch from traditional batteries for radios and kerosene lamps for light.

    EGG-energy calls itself a “for-profit company with a social mission.” It sees the provision of affordable electricity and energy as a spur for small entrepreneurs to build their businesses, boost educational opportunities through longer study time, and help with connecting families with the outside world.

    It uses regular feedback with customers to make sure their service is actually cheaper than other options – a good habit for any business looking to build a lasting customer relationship.

    “One of the key deficiencies in the energy supply chain is customer support,” said Yang. “We have seen multiple solar installations given by NGOs to community organizations that are no longer functioning because the user doesn’t have someone reliable to call or hasn’t allotted a budget to maintain the system.

    “Customer support is a key component of last mile distribution, and something that EGG-energy is focusing on as an energy services company with a local, physical presence.”

  • Global South Urbanization Does Not Have to Harm Biodiversity

    Global South Urbanization Does Not Have to Harm Biodiversity

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    How to balance fragile ecosystems with rapid urbanization will be the challenge for planners and governments across the global South in the coming years. The urbanization trend is clear: the world’s total urban area is expected to triple between 2000 and 2030, with urban populations set to double to around 4.9 billion in the same period (UNEP). This urban expansion will draw heavily on water and other natural resources and will consume prime agricultural land.

    Global urbanization will have significant implications for biodiversity and ecosystems if current trends continue, with knock-on effects for human health and development, according to a new assessment by the United Nations Convention on Biological Diversity (CBD).

    Cities and Biodiversity Outlook – the first global analysis of how projected patterns of urban land expansion will affect biodiversity and crucial ecosystems – argues that promoting low-carbon, resource-efficient urban development can counter urbanization’s adverse effects on biodiversity while improving quality of life.

    “The way our cities are designed, the way people live in them and the policy decisions of local authorities, will define, to a large extent, future global sustainability,” said Braulio Dias, Executive Secretary of the CBD.

    “The innovation lies not so much in developing new infrastructural technologies and approaches but to work with what we already have. The results often require fewer economic resources and are more sustainable,” he added.

    The report says urban expansion is occurring fast in areas close to biodiversity ‘hotspots’ and coastal zones. And rapidly urbanizing regions, such as large and mid-size settlements in sub-Saharan Africa, India and China, often lack resources to implement sustainable urban planning.

    But the study found that cities do not need to be in conflict with plant and animal species and ecosystems. They can, in fact, protect species, as is the case with Belgium, where 50 per cent of the country’s floral species are found in Brussels, or Poland, where 65 per cent of the country’s bird species occur in Warsaw.

    At the Alexander von Humboldt Research Institute in Bogota, Colombia (humboldt.org.co) researchers have been thinking about how to get this balance right and make sure the growing cities of the future are not ecological disasters.

    According to Juana Marino and Maria Angélica Mejia at the Institute’s Biological Resources Policy Program – which investigates “Biodiversity, Ecosystem Services and Urban-Regional Environments” – how cities grow and develop must change.

    They believe cities need to take into account the resources they require to function and the impact this has on biodiversity and ecosystems.

    “The more people who arrive in cities, the more they demand goods and services (in a massive way!): roads, housing, infrastructure, food, water – (creating) an impressive amount of waste, challenging traditional waste management and sanitation policies,” said Marino.

    In short, “Cities enhance consumption.”

    The Humboldt researchers believe common patterns can be seen across the global South, where ecosystems “surrounding urban areas are deforested and have significant levels of water and air pollution; they also become deeply transformed by informal settlements.”

    This process means cities “lose their ability to be resilient, they become highly vulnerable to global change and they decrease their production of ecosystem services to maintain human well-being in cities.”

    They argue that human settlements must be sustainably planned for, with ecological resilience and human well-being. If this is not done, areas suitable for agricultural production and biodiversity preservation will be harmed.

    While better planning is needed there also needs to be long-term thinking.

    But planning and managing are not the only things required: “it is a matter of design” if new “resilient” urban-rural landscapes are to be created.

    And what can be done? They believe better analysis is required and it needs to take on social and cultural knowledge, and take in the border regions around cities, the “suburban, peri-urban and other ‘transition’ landscapes should become main actors in these relationships, not mere by-products; (they are) compromise territories between a lack of definition and low governance.”

    These complex relationships with the border ecosystems of cities need to be communicated to the general public in simple, user-friendly ways so they can understand how important these areas are to the overall health of the city.

    In Latin America, the cities of Curitiba (Brazil) and Bogotá and Medellin (Colombia) have made great strides in managing and planning for biodiversity and ecosystem services, they say. But it is not just as simple as recording the number of native species and the percentage of protected areas in urban places. Links need to be created between “social, scientific and political” elements to create “socio-ecological indicators” that can be developed and turned into “easy-to-adopt mechanisms” for people to use.

    And they see innovation as the way to do this. Innovation is critical if cities and urban areas are to avoid widespread destruction of biodiversity as urbanization increases.

    “Innovation is not just an option – it is a ‘must’,” said Marino. “Not just the technical innovation already being carried on by infrastructure, transport and building sectors that are rapidly changing their patterns based on mitigation technologies.

    “Innovation is also needed in terms of biodiversity, biotechnology, information and knowledge production; appropriation, use and management. Knowledge turns into innovation when appropriated by social spheres; when it enters the social and political arenas.”

    Environmental governance can be strengthened “when promoting top-down and bottom-up innovations.”
