  • Envisioning Better Slums

    Envisioning Better Slums

    By David SouthDevelopment Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    More than 900 million people – almost a sixth of the world’s population – now live in urban slums (UN). Improving conditions for these people is a critical Millennium Development Goal target. And the scale of the problem is vast: this year half the world’s population will live in cities, and already in developing countries 43 per cent of urban dwellers live in slums. In the least-developed countries the figure is 78 per cent.

    The UN has estimated it will take US$18 billion a year to improve living conditions for these people – and most of it will have to come from the residents themselves.

    An essential route to improving the situation is to give people living in slums the dignity and respect they deserve as human beings. Initiatives across the South seek to do this and turn the situation on its head: seeing slum dwellers as a valuable asset, not an urban blight.

    The concept of ‘slum networking’ has been developed by Indian engineer Himanshu Parikh of Ahmedabad , a winner of the Aga Khan award for architecture. He starts from the point of believing there is no need for slum conditions to exist in India, but that slums do not need to be moved, just upgraded; and that good change can happen quickly. He also sees the residents’ involvement and financial contribution as critical to the sustainability of any improvements. His approach has already helped one million people overall, including 8,703 families (43,515 people) in Ahmedabad in 41 slum communities.

    Slum networking does not depend on aid funds but is a self-reliant approach, in which residents make a partnership with private suppliers to get access to the most important services first: clean water and hygiene and sanitation.

    Parikh’s approach involves providing channels for sewage, water supply and roadways in existing slum areas by exploiting the natural topography and pattern of development to provide the new infrastructure.

    Parikh makes a detailed survey plan of the existing houses and divides them into groups based on the quality of construction. If they are of reasonable quality, they are left in place. Where possible, slum dwellers are allowed to buy the land they are squatting on. By buying the land, the owner now has a direct stake in its development.

    “Working inside out, i.e. starting with quality infrastructure in the poor areas and working outwards to produce larger networks for the city or village, not only integrates the two levels, but actually produces far cheaper infrastructure at both levels,” Parikh told Architecture Week magazine.

    In the Indian city of Indore, 181 slums were networked, giving the city 360 kilometres of new roads, 300 kilometres of new sewer lines, 240 kilometres of new water lines, 120 community halls and 120,000 trees. This transformed the two local rivers from open sewers back to water. According to the World Bank, the incidence of fatal water diseases fell by 90 per cent.

    “No project for their rehabilitation could be successful until they were involved as the capital partners,” Parikh told India’s The Tribune. Upgrading “the civic amenities, including sewerage, roads and water supply, was the need of the hour for better living conditions of the slum dwellers.”

    Another initiative in Bangladesh is bringing first-rate healthcare to the country’s water-logged slum dwellers. They live in areas called ‘chars’ — effectively stranded islands surrounded by rivers, plagued by frequent flooding and physically cut-off from the country’s transport and infrastructure networks. Located in northern Bangladesh’s Jamuna river regions of Gaibandha, Kurigram and Jamalpu, these areas are very poor and overlooked by most government and foreign aid programmes. The fact the islands shift around has made it difficult for much help to reach the people.

    Bangladesh also has a severe shortage of doctors: there are 12,500 people per doctor, compared to 2,000 in Pakistan.

    But a hospital ship run by the Friendship NGO (funded by private companies and NGOs) now brings healthcare to 4 million people, treating everything from cataracts to skin infections. It sees between 200 to 250 patients a day aboard a converted former river barge. Called the Lifebuoy Friendship Hospital because of its sponsorship by Lever Brothers Bangladesh Ltd. — makers of Lifebuoy soap — it cruises the river Brammaptura, helping 172,000 people since it set sail six years ago.

    “People of the area look forward eagerly to our arrival,” said Dr Feroza Khatun, a doctor on the hospital ship. Other doctors and surgeons are provided by NGOs from Sweden, the Netherlands and France.

    The ship carries a team of two doctors and four nurses, who live on board. It provides a range of services, from basic healthcare and immunisations to minor surgery. The ship is fully equipped with modern facilities, including clinics, a pharmacy, a treatment room and an operating theatre. There is also a four-bed ward for short-term care, a pathology lab and store, x-ray unit and dark room and an electrocardiogram (ECG).

    Stays in the individual ‘chars’ are usually from three weeks to two months. When it leaves, a satellite clinic continues to provide care until the next visit. “In our satellite programmes, we bring in professionals for health and rural social education, provide paramedical care, give special treatment for mother and child health, family planning and pregnancy hazards, child nutrition and identify the needs for secondary care interventions,” said executive director Runa Khan to Bangladesh’s Star Weekend Magazine

    Started as a trial in 2001, the ship began full operations in 2002. It has been so successful, it is currently expanding by building new ships paid for by the Emirates Airline Foundation.

  • Global South Eco-cities Show How the Future Can Be

    Global South Eco-cities Show How the Future Can Be

    By David SouthDevelopment Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    The world is currently undergoing a high-stress transition on a scale not seen since the great industrial revolution that swept Europe in the 19th and 20th centuries. Today’s urban and industrial transition involves many more people and is taking place on a greater proportion of the planet. With rapid urbanization comes a demand for middle class lifestyles, with their high-energy usage and high consumption of raw materials.

    This is stretching the planet’s resources to breaking point. And as many have pointed out, if the world’s population is to continue past today’s 7 billion to reach 9 billion and beyond, new ways of living are urgently required. Radical thinking will be necessary to match the contradictory goals of raising global living standards for the world’s poor with pressured resources and environmental conditions.

    But there are innovative projects already under development to build a new generation of 21st-century cities that use less energy while offering their inhabitants a modern, high quality of life. Two examples are in China and the Middle East.

    Both projects are seen as a way to earn income and establish viable business models to build the eco-cities of the future. Each project is seeking to develop the expertise and intellectual capacity to build functioning eco-cities elsewhere. In the case of the Masdar City project in the United Arab Emirates, international businesses are being encouraged to set up in Masdar City and to develop technologies that can be sold to other countries and cities – in short, to create a green technology hub akin to California’s hi-technology hub ‘Silicon Valley’. Masdar City is also being built in stages as investors are found to help with funding. Both projects hope to prove there is money to be made in being green and sustainable.

    The Tianjin Eco-city (tianjinecocity.gov.sg) project is a joint venture between China and Singapore to build a 30 square kilometre city to house 350,000 residents.

    Tianjin (http://en.wikipedia.org/wiki/Tianjin) is a large industrial city southeast of China’s capital, Beijing. It is a place that wears the effects of its industrial expansion on the outside. Air pollution is significant and the city has a grimy layer of soot on most outdoor infrastructure.

    China has received a fair bit of criticism for its polluted cities as the country has rapidly modernized in the past two decades. This sprint to be one of the world’s top economic powers has come at a cost to the environment. In this respect, China is not unusual or alone. Industrialization can be brutal and polluting, as Europe found out during its earlier industrial revolution.

    But China is recognizing this can’t go on forever and is already piloting many initiatives to forge a more sustainable future and bring development and high living standards back in line with what the environment can handle.

    Sino-Singapore Tianjin Eco-city is the second large-scale collaboration between the Chinese government and Singapore. The first was the Suzhou Industrial Park (http://www.sipac.gov.cn/english/).The Tianjin project came up in 2007 as both countries contemplated the challenges of rapid urbanization and sustainable development.

    The project’s vision, according to its website, is to be “a thriving city which is socially harmonious, environmentally-friendly and resource-efficient – a model for sustainable development.”

    The philosophy behind the project is to find a way of living that is in harmony, with the environment, society and the economy. It is also about creating something that could be replicated elsewhere and be scaled up to a larger size.

    The city is being built 40 kilometres from Tianjin centre and 150 kilometres from Beijing. It is located in the Tianjin Binhai New Area, considered one of the fastest growing places in China.

    Construction is well underway and can be followed on the project’s website (http://www.tianjinecocity.gov.sg/gal.htm). It will be completed in 2020.

    This year, the commercial street was completed and is ready for residents to move in.

    Residents will be encouraged to avoid motorized transport and to either use public transport or people-powered transport such as bicycles and walking.

    An eco-valley runs down the centre of the city and is meant to be a place for pedestrians and cyclists to enjoy.

    The basic building block of the Eco-city – its version of a city block – is called the Eco Cell. Each Eco Cell measures 400 metres by 400 metres, a comfortable walking distance. Four Eco Cells make a neighbourhood. Several Eco Neighbourhoods make an Eco District and there are four Eco Districts in the Eco-city. It is a structure with two ideas in mind: to keep development always on a walkable, human scale and also to provide a formula for scaling up the size of the Eco-city as the number of residents increases.

    It is a logical approach and seeks to address one of the most common problems with conventional cities: sprawling and unmanageable growth that quickly loses sight of human need.

    Agreement was also reached on the standards that should be achieved for a wide variety of criteria, from air and water quality to vegetation, green building standards, and how much public space there should be per person.

    An ambitious project in the United Arab Emirates is trying to become both the world’s top centre for eco cities and a living research centre for renewable energy. Masdar City (http://www.masdarcity.ae/en/)is planned to be a city for 40,000 people. It is billed as a high-density, pedestrian-friendly development where current and future renewable energy and clean technologies will be “marketed, researched, developed, tested and implemented.”

    The city hopes to become home to hundreds of businesses, a research university and technology clusters.

    This version of an eco-city is being built in three layers in the desert, 17 kilometres from the Emirati capital Abu Dhabi. The goal is to make a city with zero carbon emissions, powered entirely by renewable energy. It is an ambitious goal but there are examples in the world of cities that use significant renewable energy for their power, such as Reykjavik, Iceland in Northern Europe, which draws much of its energy from renewables and geothermal sources.

    Masdar City is designed by world-famous British architect Norman Foster (fosterandpartners.com) and will be 6.5 square kilometres in size.

    The design is highly innovative. The city will be erected on 6 metre high stilts to increase air circulation and reduce the heat coming from the desert floor. The city will be built on three levels or decks, to make a complete separation between transport and residential and public spaces.

    The lowest deck will have a transportation system based on Personal Rapid Transport Pods. These look like insect eyes and are automated, controlled by touch screens, using magnetic sensors for propulsion. On top of this transport network will be the pedestrian streets, with businesses, shops and homes. No vehicles will be allowed there, and people will only be able to use bicycles or Segway (segway.com) people movers to get around. An overhead light railway system will run through the city centre, all the way to Abu Dhabi City.

    “By layering the city, we can make the transport system super-efficient and the street level a much better experience,” Gerard Evenden, senior partner at Foster + Partners, told The Sunday Times. “There will be no car pollution, it will be safer and have more open spaces. Nobody has attempted anything like this.”

    Masdar City is being built in stages as funding comes, with the goal of completion by 2016. It hopes to achieve its aspiration to be the most technologically advanced and environmentally friendly city in the world. As for water supplies in the desert, there is a plan: dew collected in the night and morning and a solar-powered desalination plant turning salt water into drinking water.

    Electricity will come from a variety of sources. Solar panels will be on every roof and double as shade on alleyways. Non-organic waste will be recycled, while organic waste will be turned into fuel for power plants. Dirty water will be cleaned and then used to irrigate green spaces. Because of the design, the planners hope the city will just use a quarter of the energy of a conventional city.

    To keep the city smart and the project on top of developments in renewable energy, the Masdar Institute of Science and Technology (http://www.masdar.ac.ae/) will specialize in renewable energy technology.

    The cost for the city was pegged at US $22 billion in 2009.

    The chief executive of Masdar – Abu Dhabi’s renewable-energy company – is Sultan Al Jaber. He sees the city as a beacon to show the way for the rest of the Emirate to convert from a highly inefficient consumer of energy to a pioneer in green technology.

    “The problem with the renewable-energy industry is that it is too fragmented,” he told The Sunday Times. “This is where the idea for Masdar City came from. We said, ‘Let’s bring it all together within the same boundaries, like the Silicon Valley model (in California, USA).’”

    The project needs to gather much of its funding as it progresses. The United Nations’ Clean Development Mechanism (http://cdm.unfccc.int/) is helping with financing. Companies can earn carbon credits if they help fund a low-carbon scheme in the global South. The sultan is ambitious and sees this as a “blueprint for the cities of the future.” It has been able to bring on board General Electric (GE) and the Massachusetts Institute of Technology (MIT) to sponsor the university.

    It is possible to visit Masdar City and take a tour (http://www.masdarcity.ae/en/105/visit-masdar-city/) and it is also possible to view online what has been built so far (http://www.masdarcity.ae/en/32/built-environment/).

  • Egyptian Youth Turns Plastic Waste into Fuel

    Egyptian Youth Turns Plastic Waste into Fuel

    By David SouthDevelopment Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    The challenge of finding alternate fuel sources is capturing the imagination of innovators across the global South. As the world’s population increases – it recently reached 7 billion (UN) – and the number of people seeking a better life grows in turn, the energy demands on the planet are pushing up competition for existing conventional fuel sources.

    The modern lifestyle that many aspire to requires energy, whether it’s using electronic products which consume large quantities of electricity, driving personal vehicles or living in homes that are artificially heated and cooled.

    This energy hunger has opened up a whole new market demand that needs to be met. The scale of this market is enormous, but the solutions are ultimately limited only by people’s imaginations. An award-winning Egyptian teenage scientist is capturing attention for the imaginative solution of turning waste plastic into biofuel, sparking interest in the creation of a whole new source of wealth for her country.

    Sixteen-year-old Azza Abdel Hamid Faiad (http://tinyurl.com/dysemjg) has found a new way to take waste plastic and break it down into fuel. She has discovered aluminosilicate minerals (http://en.wikipedia.org/wiki/Aluminosilicate) – which contain aluminium, silicon and oxygen and are found in clays – can break down the polymers that make up plastic (http://en.wikipedia.org/wiki/Polymer) to produce the gases methane, propane and ethane, all of which can be turned into ethanol (http://en.wikipedia.org/wiki/Ethanol), which is useful as a biofuel.

    According to Inhabitat (inhabitat.com), a website dedicated to “green design, innovation, and the future of clean technology,” her solution could turn the country’s annual consumption of 1 million tonnes of plastic into a year’s supply of biofuel worth US $78 million.

    Clever innovators are sitting on a goldmine if they can come up with renewable energy solutions. The U.S. Army alone is looking to spend US $7 billion on renewable energy sources and is accepting bids from the private sector to meet its needs (http://www.forbes.com/sites/toddwoody/2012/08/08/u-s-army-opens-bids-to-buy-7-billionin-renewable-energy/). The army is looking to sign contracts stretching up to 30 years for buying electricity generated by solar, wind, geothermal and biomass projects.

    The options are numerous for renewable energy – from solar power to wind power to algae as a source of biofuels (http://en.wikipedia.org/wiki/Biofuel). The challenge is to find a fuel source that is plentiful, renewable, and crucially, doesn’t harm other needs.

    Using biofuel as a replacement for conventional petroleum-based fuels like gasoline and diesel appears to be an attractive solution, but it can lead to other problems. Some people are using used cooking oils to convert into biodiesels, but sometimes there is not enough used cooking oil to meet demand. In short, a constant supply source is required to meet ever-increasing energy demand.

    A famous example of where the use of renewable plant-based fuel sources can go wrong is the case of corn. The widespread use of corn as a source for biofuels – rather than for animal feed or human food – has led to accusations this is contributing to the global food crisis. The current drought in the United States is damaging corn crops and only making this problem more acute. The U.S. is the world’s largest producer of corn (US Department of Agriculture) and much of it is used as livestock feed around the world.

    Faiad’s solution is appealing because the fuel does not come from biomass – derived from plant matter – but turns waste plastic into the raw material for biofuel.

    Plastic waste is a common byproduct of modern life. Plastic is used extensively in packaging, bottles, bags and electronic products. It fills up landfill sites and is a blight on the landscape in many countries. It is also a product made from petrochemicals (http://en.wikipedia.org/wiki/Plastic), the very source of conventional fuel used by most of the world’s vehicles.

    Breaking down waste plastic from bottles, packaging and other products into what is called ‘biofuel feedstock’ – the substance necessary to start the creation of biofuel – requires a means to turn the plastic into fuel.

    According to Green Prophet (greenprophet.com), Faiad believes her technological breakthrough “can provide an economically efficient method for production of hydrocarbon fuel namely: cracked naphtha (http://en.wikipedia.org/wiki/Petroleum_naphtha) of about 40,000 tons per year and hydrocarbon gases of about 138,000 tons per year equivalent to US $78 million.”

    This could be a big economic boost to Egypt’s economy, simultaneously reducing dependence on petroleum-based fuels and creating a new source of income. Egypt’s economy has been hit hard since the start of the Arab Spring (http://en.wikipedia.org/wiki/Arab_Spring). The number of tourists fell 33 per cent in 2011 and revenue dropped by US $3.7 billion from 2010 (Egyptian Tourism Minister). In 2009 about 12.5 million tourists visited Egypt, bringing revenue of US $10.8 billion. The tourism sector is one of the country’s top sources of foreign revenue, accounting for more than 11 per cent of GDP, and offers jobs in a country beset by high unemployment – for Egypt, tourism makes up 11 per cent of its GDP (gross domestic product) (Reuters).

    Faiad’s innovation has not gone unnoticed. She received the European Fusion Development Agreement award (http://www.efda.org/) at the 2011 23rd European Union Contest for Young Scientists (http://ec.europa.eu/research/youngscientists/index_en.cfm). She is also receiving interest from the Egyptian Petroleum Research Institute (http://www.epri.sci.eg/), according to Inhabitat.

    Ambitious Faiad is also seeking to take ownership of her innovation by getting a patent from the Egyptian Patent Office (http://www.egypo.gov.eg/english/default.htm).

  • Biogas Digester-in-a-Bag Brings Portability

    Biogas Digester-in-a-Bag Brings Portability

    By David SouthDevelopment Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Securing energy sources that are cheap (or free) and renewable can significantly reduce the cost of living for the world’s poor. The cost of fuel for essentials such as cooking and lighting can quickly eat up household incomes.

    Gaining access to an inexpensive gas source that is also renewable can help people divert their income into other things, such as education and health care, improving individuals’ well-being and helping boost wealth.

    Biogas (http://en.wikipedia.org/wiki/Biogas) is fuel made from biodegradable organic material such as kitchen, animal or human waste. It can be converted into gas either by being heated or using anaerobic bacteria to break down the material and turn it into combustible methane gas (http://en.wikipedia.org/wiki/Methane).

    Most biogas systems are complex and large, involving an enormous domed biodigester.

    But a clever solution from Kenya, the Flexi Biogas system (biogas.co.ke), is different. It is designed to be highly portable and scalable depending on a person’s needs. The Flexi Biogas system is a pillow-shaped PVC tarpaulin, measuring 6 metres by 3 metres. It comes in two parts: a plastic digester bag on the inside and a greenhouse-like plastic tunnel on the outside. The tunnel traps heat and keeps temperatures between 25 and 36 degrees Celsius.

    Subjected to the heat of the sun, the environment inside the bag encourages microbes to digest the organic material – or substrate (http://en.wikipedia.org/wiki/Enzyme_substrate_%28biology%29) as it is known, releasing biogas bubbles and inflating the bag with methane. This gas is then sent through a PVC tube that can be connected to a gas-burning appliance such as a cooking stove.

    Currently, most people use the biogas for lighting and cooking but it also produces enough gas to run agricultural machinery.

    The Flexi Biogas digester sits on the ground and so is easy to observe and understand.

    The Flexi Biogas system is designed, built and sold by Kenya’s Biogas International, which has sold 200 of the systems since 2011. In 2012, the company partnered with IFAD – the United Nations’ International Fund for Agricultural Development (ifad.org) – to install nine systems on dairy farms in Kenya. These Flexi Biogas systems use kitchen and human waste to produce electricity for lighting and to provide Internet service.

    Cows produce 15 to 30 kilograms of dung a day (IFAD). By placing 20 kilograms of fresh cow dung into a Flexi Biogas digester it is possible to produce 1,000 litres of cooking gas – enough gas for a family of five to seven people. This amount of cow dung could also produce enough gas to run a 5 horsepower engine for one hour. The engine could also be connected to a car alternator to generate electricity to run lights, a computer or a television set.

    A Flexi Biogas system costs US $410, including installation by technicians and all the extras including inlet and outlet pipes and a 15 metre gas pipe.

    The cost of the system increased from the first prototypes. Initially, inexpensive plastic was used for the bags and the total cost for the system was US $180. But the makers encountered a problem with durability – the systems were prone to tearing and needed to be replaced after two years. Since then, they have moved to a more expensive PVC tarpaulin bag designed to last 10 years.

    The makers point out that access to high-quality plastic and rubber in Kenya is difficult and the system’s costs could be brought down if they were manufactured in China or India.

    The makers argue there are several reasons why the Flexi Biogas solution is suited to Africa. One is the difficulty of securing land tenure, necessary for the building of a permanent structure like a biodigester dome. It can also be a challenge to find skilled labour and get access to complex parts such as gas pressure regulators.

    In a comparison between the conventional dome biogas digester and the Flexi Biogas system, IFAD found the average cost in Kenya for a dome system was US $1,000, compared to US $410 for the Flexi Biogas system. A fixed dome takes 21 days on average to set up while a Flexi Biogas system can be set up in a day. The Flexi Biogas system also turns the substrate into biogas faster and can operate at higher temperatures. IFAD found various advantages and disadvantages to the Flexi Biogas solution: it is relatively inexpensive, lightweight (10 kilograms), very portable, quick and simple to set up, and easy to operate. The disadvantages include being costly to make, easy to steal, and a relatively short lifespan.

    Weighing it all up, IFAD still concluded that “the Flexi Biogas system is an affordable solution that provides household energy while making use of waste products that would otherwise add to emissions.”
