  • Bolivia Grabs World Media Attention with Salt Hotel

    Bolivia Grabs World Media Attention with Salt Hotel

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Tourism is a great way to attract foreign currency to a country and build local economies, especially in remote or isolated places. But the catch is finding a way to get people to go the distance and come and visit and spend their money.

    In a global South twist on the well-known Ice Hotel in Sweden(www.icehotel.com) – a hotel entirely built out of ice – enterprising Bolivians have built a hotel out of salt.

    A Bolivian hotel in the middle of the world’s largest salt flats has found a clever way to attract tourists to this remote holiday destination: build the hotel entirely out of salt, right down to its furniture.

    The South American nation is one of the poorest inLatin America, and its income distribution is among the region’s most unequal. Bringing in foreign currency and attracting more tourists can help to reduce this poverty. According to the World Travel and Tourism Council, travel and tourism will contribute 2 percent to the country’s gross domestic product (GDP) in 2011. Around 75,000 jobs are directly dependent on the tourism business in the country and this is projected to rise to 96,000 jobs by 2021.

    And it is a good business to be involved in: “Travel and tourism is one of the world’s great industries, providing 9 percent of global GDP and 260 million jobs; it drives economic growth, business relationships and social mobility,” according to David Scowsill, President and CEO of the World Travel and Tourism Council.

    The Hotel de Sal Cristal (http://www.hosteldesal.com/?L=2), near Colchani, hosts guests who come to visit the salt flats of Salar de Uyuni (http://en.wikipedia.org/wiki/Salar_de_Uyuni). They are believed to store 50 to 70 percent of the world’s lithium supplies and an economic boom has started in the area. The striking and blinding white salt flats were featured in the James Bond film “Quantum of Solace.”

    The hotel’s unique construction from rock-hard salt hewn from the salt flats is working to encourage tourists to stay longer in the area during their holiday. Before, they would just take a quick excursion on to the salt flats before moving on to their next destination.

    The Hotel de Sal Cristal is built using blocks of salt cut from the surrounding flats. The architectural design is inspired by the ancient Chinese balancing philosophy of Feng Shui (http://en.wikipedia.org/wiki/Feng_shui). Following the principles of the philosophy, it faces the sun and balances both masculine and feminine energies. Shaped like three coca leaves, the feminine side, this balances with the more masculine side reflected in the salt flats, the hotel’s website claims.

    The hotel has 27 rooms with hot water and heating. – and beds made of salt. In the dining room, people can sit on chairs made of salt and eat at salt tables. The rooms are wall-to-wall salt, bright and white.

    The hotel’s pool is surrounded by sand-like salt.

    The hotel’s ‘Resto-Bar’ offers views of the salt flats and promises it will “allow the cosmic energy…” to flow freely.

    The menu offers llama meat and risotto of quinoa (http://en.wikipedia.org/wiki/Quinoa) alongside traditional Bolivian dishes, salads and soups and Bolivian-themed treats.

    The hotel has an ‘astronomic observatory’ for star gazing, making the most of the low level of light pollution on the flats.

    One of the hotel’s tour guides, Pedro Pablo Michel Rocha from Hidalgo Tours (http://www.salardeuyuni.net/), told the Daily Mail newspaper: “I love it when visitors come to this place for the first time.

    “They can’t get over the fact that everything is made out of salt and I’ve even seen a few people lick the furniture to make sure!

    “It is a wonderful experience to come somewhere like this where they’ve used the natural materials available to create something like a hotel.”

    The salt flats, formed from prehistoric lakes, have a salt crust hard-baked by the sun with a pool of salty water underneath which is rich in the rare element lithium. Lithium (http://en.wikipedia.org/wiki/Lithium) is sought-after for its use in things like re-chargeable batteries for mobile phones, computers and electric cars.

    The area’s economy has boomed since 3.4 million tons of lithium – believed to be half the world’s supply – was discovered underneath the salt flats.

    The power of tourism to alleviate poverty has been documented by Caroline Ashley, co-author of Tourism and Poverty Reduction: Pathways to Prosperity (http://www.earthscan.co.uk/?TabId=92842&v=497073), after extensive research on tourism’s impact on poverty in countries across Africa andAsia.

    She argues that “tourism can fight poverty.”

    “Note, we say ‘can’, not that it always does. The share of spending by tourists within a destination that reaches poor people can vary from less than 10 percent to a high of 30 percent,” Ashley told BusinessFightsPoverty (http://www.businessfightspoverty.org).

    “When it works, international tourism is actually a very good way of channelling resources from rich to poor. In destinations as diverse as hiking on Mount Kilimanjaro in Tanzania, business tourism in Vietnam and cultural tourism in Ethiopia, between one quarter and one third of all in-country tourist spending accrues to poor households in and around the destination.”    

    Ashley said a successful tourism strategy needs to focus on “the 4Ps: pay, procurement, persuasion and partnership.”

    “Pay a living wage to local employees; take a hard look at procurement and potential to source locally … persuade – or at least inform – your clients how to take up opportunities to spend in the local economy…” and build a partnership with government to integrate tourism into the local economy.

    And it looks like the hotel can’t get more connected to the local economy than being made of the very salt that surrounds it.

  • Toilet Malls Make Going Better

    Toilet Malls Make Going Better

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    Across the global South, clever entrepreneurs are transforming services that were bare-bones, grim and out-of-date into modern facilities packed with features that help to pay for their operation. In Kenya, an entrepreneur has used this approach to transform the poor quality of public toilets.

    Public sanitation is essential for good health and a high quality of life. Around the world, more than 2.6 billion people, or 41 percent of the world’s population, are without access to basic sanitation. As a result, most have to make do and defecate or urinate wherever they can. In crowded urban areas, the result is an unpleasant source of disease and filth that fouls living spaces and sickens or kills many people.

    Nairobi’s slums are notorious for so-called ‘flying toilets’ or ‘scud missiles’: plastic bags filled with excrement that act as the only toilet available for many. Half the population also has no access to clean water. It has been estimated these appalling conditions contribute to up to 50 percent of health problems for slum dwellers.

    The Iko Toilet started by David Kuria first came to life in Nairobi’s central business district.

    “What we saw in the last 10 years, the few public toilets that existed were in very poor shape,” he told CNN. “In fact they had been taken over by the street boys, and they were a point for mugging and drug trafficking. With that background we needed some sort of social transformation. For people to gain the confidence that you could have a public toilet which is clean which is safe and you can go in and come out the same way.”

    The solution was “toilet malls,” complete with a range of on-site micro businesses to make going to the public toilet attractive. Apart from music and radio to listen to, there is a shoe shining service, snack bars selling fruit and water, and even banking services. The idea is that the micro businesses pay for the upkeep and cleaning of the toilet. And their presence also keeps the toilets safe because there is always somebody around.

    While the concept was pioneered in the business district, it is now moving out into Nairobi’s slums. So far, Kuria has completed 12 toilets in Nairobi and has another 18 under development. He is also rolling out the toilets to other parts of the country. He receives the plots of land from local municipalities and his company, Ecotact, builds the toilets.

    It costs five Kenyan shillings (US .07 cents) to use the toilets.

    Kuria had become frustrated with the city council’s inability to provide clean and safe public toilets.

    “I thought for some time before coming up with the idea,” he told The Nation. “People had nowhere to go and thugs were holding them to ransom in the few facilities then run by the council.”

    Kuria said people are leaving good comments about the toilets and say it makes them proud to be Kenyan.

    The cost to build a toilet is Sh 2 million (US $26,000) and the toilet is managed by Kuria for five years. At the end of the contract, he will hand them over to the local council.

    “We are getting support from UNDP and other partners like East African Breweries, the Global Water International and the Rotary International,” he said.

    An architect by training, Kuria is hoping to employ more than 1,000 people by the end of this year. So far 120 people work for the Iko Toilets. Like so many others, he is also affected by chronic water shortages.

    “We are worried because when there is scarcity of water, we are forced to buy it at an additional cost,” he said.

    Private vendors currently provide the water for the toilet malls.

    Iko Toilets are so successful they have made it into the ‘Hall of Fame’ at the World Toilet Organization (http://www.worldtoilet.org/). Kuria was also winner of the World Economic Forum’s Africa Entrepreneur of the Year award earlier this year.

    And his ambitions extend beyond Kenya.

    “We also want to go to other countries. Uganda, Rwanda and South Africa have already approached me for Iko Toilets,” he said.

  • Successful Fuel-Efficient Cookers Show the Way

    Successful Fuel-Efficient Cookers Show the Way

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    A Kenyan entrepreneur has cooked up a fuel-efficient stove and oven that uses less of a precious national resource: wood from trees.

    Most African households using fuel-burning stoves either cannot afford clean-burning fuels like natural gas or electric stoves, or do not have access to them. They are stuck having to burn wood or other materials like animal dung – collectively called biomass – on open fires.

    As well as using up wood and contributing to deforestation, there is another downside to these stoves. 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 global deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).

    Two solutions in Kenya are helping people to cook more efficiently (meaning less time wasted on gathering material to burn, and less fuel used) and reducing cooking time by using heat more effectively.

    Invented by Dr Maxwell Kinyanjui, the Kinyanjui Jiko is a fuel-efficient charcoal oven that comes in small, medium and large industrial sizes. Made entirely in Kenya, the ovens are custom designed for a variety of environments, from domestic household use and on-the-go safari models to high-capacity models for micro-enterprises and large institutions. Cooks can use the ovens to bake, toast, steam or boil. And they are 40 percent cheaper than cooking with electricity and between 15 and 20 percent cheaper than gas.

    Kinyanjui’s Musaki Enterprises Ltd. (www.reskqu.blogspot.com/2009/01/arboretum-project.html) has developed a reputation for pioneering work in developing fuel-efficient stoves and ovens. Its most popular success to date has been the Kenya Ceramic Jiko (jiko is Swahili for cooker), or KCJ, a cheap, simple and effective stove. The company was set up in 1992, but has been involved in international aid-funded research and development efforts since the 1980s.

    “My dad was on a very good team of highly motivated individuals in the early 80s who developed the stove through pragmatism, logic and good old-fashioned ingenuity,” said his son, Teddy Kinyanjui. “He then set up the independent Musaki Enterprises.”

    The KCJ uses a ceramic liner placed inside a metal container. The metal is usually recycled, often taken from 55 gallon steel drums. The ceramic liner stops the heat energy from simply escaping into the environment and helps to focus the heat on cooking. Simply adding the ceramic liner reduces the stove’s fuel consumption by between 25 and 40 percent. The charcoal or wood sits in the ceramic basin and the burnt ash falls through holes in the bottom of the liner.

    The stove design was a result of international and Kenyan cooperation, and has become popular in many African countries, including Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal and Sudan. It is used in 50 percent of urban homes in Kenya and 16 percent of rural homes.

    Musaki Enterprises say the KCJ stoves on average save between 1 and 1.5 tons of CO2 per stove per year compared to other models. In supermarkets, the KCJs retail for around US $5 and the Kinyanjui Jiko ovens start at around US $100.

    The deployment of the KCJ stoves has helped in slowing the deforestation of the country, but has not been able to bring it to a halt because of population growth and poor re-forestation efforts, says Teddy Kinyanjui.

    “The lack of forward planning in tree planting is making firewood and charcoal harder and harder to obtain,” he said. “Fossil fuels are unavailable or unaffordable. Tree planting must begin now on a huge scale for people to continue cooking.”

    Teddy won’t reveal how profitable the KCJ stoves have been, but says, “I wouldn’t have gone to school if they didn’t sell well.”

    “Well, more and more people keep buying the damn things as fast as we can make them, so I think our customers like them,” he said. “They really all seem to like that the stoves cook really well for really cheap and are very high quality.”

  • African Ingenuity Attracting Interest

    African Ingenuity Attracting Interest

    By David South, Development Challenges, South-South Solutions

    SOUTH-SOUTH CASE STUDY

    The tide of science and innovation from the South is grabbing the world’s attention. While the big giants of India, China and Brazil are well-established hubs of invention, it is the once-overlooked continent of Africa that is generating current excitement. The atmosphere can be equated to the flush of innovation in the late 19th and early 20th centuries, as inventors tackled the budding new technologies of the combustion engine, flight, electricity and radio waves. These days, it’s the challenges of development, rapid urbanization and finding ways to ‘hack’ (http://en.wikipedia.org/wiki/Hack_%28technology%29), like adapting existing  technology such as mobile phones or bicycles to new purposes.

    That previous period of invention had a spirit of pioneering and making-do, of dreams and adaptability triumphing over poverty, and it laid the path for many new companies to sprout up and create wealth and jobs for millions. At this August’s Maker Faire Africa gathering (http://makerfaireafrica.com/) in Accra, Ghana, African pioneers in grassroots innovation offered inspiring inventions.

    The rapid changes happening in African countries – especially the tilt to having a larger urban population than a rural one – means there is an urgent need to boost incomes.

    Handled right, these grassroots inventors could grow to become part of the already expanding South-South trade, which grew by an average of 13 percent per year between 1995 and 2007, to make up 20 percent of world trade.

    Inspired by the US magazine Make (http://makezine.com/) – a do-it-yourself technology magazine written by makers of computers, electronics and robotics – the first Maker Faire gathering was held in 2006 in the San Francisco area of the United States.

    The African Maker Faire modelled itself on this approach and has tapped into Africa’s well-entrenched do-it-yourself development culture. It went looking for more inventors like those celebrated on the website AfriGadget (http://www.afrigadget.com/), with its projects that solve “everyday problems with African ingenuity.” The Faire works with the participants to share their ideas and to find ways to make money from their ideas.

    The Faire in Accra ran in parallel with the International Development Design Summit (http://2009.iddsummit.org/),which came to Ghana from its home at the Massachusetts Institute of Technology (http://web.mit.edu/) in the United States. Its aim was to bring technology closer to “potential end users of the projects.”

    “It is part of the revolution in design that aims to create equity in the distribution of research and development resources by focusing on the needs of the world’s poor,” organizers said.

    This spirit of African invention is about breaking the perception that invention is a purely Northern phenomenon that requires complex and expensive materials. African ingenuity is about taking whatever is available and tackling common problems. It is an empowering approach that celebrates local initiative and seeks to find ways to turn these inventions into sustainable incomes.

    “What’s different about African mechanics and gadgets is that it’s generally made with much fewer, and more basic, materials,” said Afrigadget founder Erik Hersman. “Where you might find a story on how to make hi-tech robots at home in Make, its counterpart in Africa might be how to create a bicycle out of wood. No less ingenuity needed, but far more useful for an African’s everyday life.”

    The African Maker Faire featured a wide range of solutions, from a low-power radio station to a bicycle-powered saw and a simple corn planter.

    Shamsudeen Napara, from northern Ghana, brought a US $10 corn planter that looks like a pill dispenser to help speed up crop planting. He also has invented a cheap shea nut (http://en.wikipedia.org/wiki/Shea_butter) roaster. These inventions are cooked up in his metal fabrication shop which builds tools for agricultural use. Shea nut processing is a lucrative task for women in Northern Ghana. Napara’s roaster costs US $40 and reduces the energy and time to process the nuts. He has also made a soap cutter using piano wires and guitar screws.

    Bernard Kiwia, a bicycle mechanic from Arusha, Tanzania, is a pioneer working with windmills, water pumps, mobile phone chargers and pedal-powered hacksaws – all made from old bike parts.

    Hayford Bempong, David Celestin and Michael Amankwanor from Accra Polytechnic (http://www.accrapolytechnic.edu.gh/), built a low-power radio station. Made from scrap electronic parts and an antenna from copper pipe, the radio was put straight to use to broadcast announcements at the event over a range of a few thousand metres.

    Suprio Das, Killian Deku, Laura Stupin and Bernard Kiwia brought a method to produce chlorine from salt water and other common materials. It can then be used to purify water. Their method can clean vast quantities of water using no moving parts (avoiding breakdowns). It does this by dripping chlorine into the water until a level has been reached, and then the purified water is released. By using a 5 litre bag of chlorine, and a US $3 valve, 100,000 litres of water can be purified.

    Electricity was also being made using low-cost batteries from aluminum cans and plastic water bottles. Applying salt water as an electrolyte (http://en.wikipedia.org/wiki/Electrolyte),electricity is created by the oxidation of the aluminum can – a cheaper approach and less toxic than commercial batteries.

    A group called Afrobotics (http://www.afrobotics.com) gave a presentation to encourage more African students to go into engineering, science and technology. Afrobotics is set up as a competition to “fuel engineering, science, innovation, and entrepreneurship on the African continent, utilizing robotics.” They have some excellent videos of African robots in action: http://www.afrobotics.com/videos.
