Nanotechnology in the developing world/global south

Sometimes it’s called the ‘developing world’, sometimes it’s called the ‘global south’ and there have been other names before these. In any event, the organization, Nanotechnology for Development (Nano-dev) has released a policy brief about nanotechnology and emerging economies (?). Before discussing the brief, I have found a little information on the organization. From the Nano-dev home page,

Nanotechnology for development is a research project that aims at understanding how nanotechnology can contribute to development. By investigating way people deal with nanotechnology in Kenya, India and the Netherlands, the project will flesh out appropriate ways for governing nanotechnology for development.

Nanotechnology is a label for technologies at the nano-scale, roughly between 1 and 100 nanometers. This is extremely small. By comparison, the diameter of one human hair is about 60,000 nanometers. At this scale materials acquire all sorts of new characteristics that can be used in a wide range of novel applications. This potentially includes cheaper and more efficient technologies that can benefit the world’s poor, such as cheap water filters, efficient solar powered electricity, and portable diagnostic tests.

The four team members on the Nano-dev project are (from the Project Team page):

Pankaj Sekhsaria’s project seeks to understand the cultures of innovation in nanotechnology research in India, particularly in laboratories. He has a Bachelors Degree in Mechanical Engineering from Pune University in India and a MA in Mass Communication from the Jamia Milia Islamia in New Delhi, India.

Trust Saidi’s research is on travelling nanotechnologies. He studied BSc in Geography and Environmental Studies at Zimbabwe Open University, BSc Honours in Geography at University of Zimbabwe, MSc in Public Policy and Human Development at Maastricht Graduate School of Governance, Maastricht University.

Charity Urama’s project investigates the role of knowledge brokerage in nanotechnology for development. She obtained her BSc Botany from the faculty of Biological Sciences, University of Nigeria, Nsukka and MSc from the school of Biological and Environmental Sciences, Faculty of Life sciences, University of Aberdeen (UK).

Koen Beumer focuses on the democratic risk governance of nanotechnologies for development. Koen Beumer studied Arts and Culture (BA) and Cultures of Arts, Science and Technology (MPhil, cum laude) at Maastricht University.

According to the April 4, 2012 news item on Nanowerk about the brief,

The key message of the policy brief is that nanotechnology can have both positive and negative consequences for countries in the global South. These should be pro-actively dealt with.

The positive consequences of nanotechnology include direct benefits in the form of solutions to the problems of the poor and indirect benefits in the form of economic growth. The negative consequences of nanotechnology include direct risks to human health and the environment and indirect risks such as a deepening of the global divide. Core challenges to harnessing nanotechnology for development include risk governance, cultures of innovation, knowledge brokerage and travelling technology.

What I found particularly interesting in the policy brief is the analysis of nanotechnology efforts in countries that are not usually mentioned  (from the policy brief),

There are large differences amongst countries in the global South. Some countries, like India, Egypt, Brazil and South Africa, have invested substantial sums of money through dedicated programs. Often these are large countries with emerging economies. Dedicated programs and strategies have been generated with strong political support.

In other countries in the global South things look different. Several African countries, like Nigeria, Kenya, Uganda and Zimbabwe have expressed their interest in nanotechnologies and some activities can indeed be observed. But generally this activity does not exceed the level of individual researchers and incidental funding. [p. 3]

In addition to the usual concerns expressed over human health, they mention this risk,

Furthermore, properties at the nano-scale may be used to imitate the properties of rare minerals, thus affecting the export rates of their main producers, usually countries in the global South. Nanotechnologies may thus have reverse effects on material demands and consequently on the export of raw materials by countries in the global South (Schummer 2007). [p. 3]

Interesting thought that nanotechnology research could pose a risk to the economic welfare of countries that rely on the export of raw materials. Canada, anyone? If you think about it, all the excitement over nanocellulose doesn’t have to be an economic boon for ‘forestry-based’ countries. If cellulose is the most abundant polymer on earth what’s stop other countries from using their own nanocellulose. After all, Brazilian researchers are working on nanocellulose fibres derived from pineapples and bananas (my Mar. 28, 2011 and June 16, 2011 postings).

One final thing from the April 4, 2012 news item on Nanowerk,

The NANO-DEV project is partnership of three research institutes led by Maastricht University, the Netherlands. Besides Maastricht University, it includes the University of Hyderabad (India) and the African Technology Policy Studies Network (Kenya).

Tanzania’s Dr Hulda Shaidi Swai

I’ve developed a pet peeve over the years about Africa being discussed as if it were a country and not a continent made up of diverse countries and peoples. So, I was particularly delighted to find Robert Mpinga’s Jan. 26, 2012 article discussing Dr. Hulda Shaidi Swai’s nanomedicine work and his opinion of the differing approaches to research and development (R&D) followed in Tanzania and South Africa. From Mpinga’s Jan. 26, 2012 article for allAfrica,

One of our [Tanzania’s] own daughters, Dr Hulda Shaidi Swai, is currently making news across the world in her pioneering work that seeks to employ “nanotechnology” to treat TB and what she calls ‘other diseases of poverty’ more efficiently – and in less the time it takes now – yet still hopes to do so in safer ways.

There is no prize for guessing why you haven’t heard about her: she is doing all this from the comfort of the Council for Scientific and Industrial Research (CSIR), a South African centre of excellence based in Pretoria. In many ways, Dr Swai embodies our country’s collective failure to accommodate people who think and act outside the box of our comfort zones.

Not surprisingly, Hulda could well be poised to make global waves even as we at home remain locked in mundane debate over the safety and perceived dangers of farming GM (genetically modified) crops – a field of science which now pales into yesteryear in the face of new advances of ‘nano’ frontiers.

Dr. Swai has received some very impressive support for her work,

The moral of Dr Swai’s story is not that she has set out on mission impossible; in fact, she has already marshaled a team of 19 people to her stable — the Nanomedicine Platform for Infectious Diseases of Poverty – which includes seven post-doctorate scientists, three PhD and four Masters of Science (MSc) students, two technicians and a project manager.

She also has the backing of the top leadership in South Africa, including former president Thabo Mbeki and the country’s minister responsible for science and technology. The commitment and imagination of all these men and women have been fired from a dream of this single Tanzanian woman scientist, but their combined resolve to act as a team has since won them global support: US $100,000 in project support from the Melinda and Bill Gates Foundation – through its ‘Grand Challenges Exploration’ programme — the only one of two such awards in Africa to date, and an EU approval for its provisional application for intellectual property (IP) protection of its pioneering work on a novel anti-TB drug therapy delivery system.

Dr. Swai is critical of research being done in rich countries,

“The scientists in rich countries are only interested in diseases that affect them … not malaria.”

You’ll find more details about Swai’s work and more about her opinions  in Mpinga’s article. The ‘Grand Challenges Explorations’ programme was also mentioned in my Dec. 22, 2011 posting when a series of major grants  (some to researchers in Canada) was announced.

Media piracy study and Canada’s International Development Research Centre

Canada’s International Development Research Centre (IDRC) helped to fund (along with the Ford Foundation) a massive study on media piracy in emerging economies led and published by the US Social Sciences Research Council in March 2011. It was a global effort also supported by Brazil’s Overmundo Institute and the Center for Technology and Society, Getulio Vargas Foundation; India’s Sarai: The Centre for the Study of Developing Societies and The Alternative Law Forum; South Africa’s The Association for Progressive Communication; Russia’s The Centre for Independent Social Research and The Moscow Institute of Physics and Technology; and the US’s The Program on Information Justice and Intellectual Property. I half expected to see China listed too and I find the absence surprising.

It was a March 8, 2011 posting by Mike Masnick on Techdirt that alerted me to the study. (from the posting),

… much in the report is extremely forward-looking and thinking. It goes into great detail how fascinating and innovative new business models are appearing around the globe where “piracy” is rampant, and suggests that we really need to rethink the idea of “piracy” in those markets. It highlights how almost all of the policy discussions in the west concerning infringement focuses on “enforcement,” but that may be the wrong way to go about it. The research, instead, points out that a better focus may be on setting up the structures for successful business models to emerge — which include local firms who can compete on prices …

The 440 page report, Media piracy in Emerging Economies, is available under various licensing agreements (free and pay).

Yesterday (June 1, 2011), I received a media advisory from the IDRC informing me of a panel discussion being held tomorrow, June 3, 2011,from 2 pm to 4 pm EDT in Ottawa (if you can’t get to the live panel discussion, you can view it via livestreaming webcast). From the media advisory,

Media Piracy in Emerging Economies, a landmark study co-funded by Canada’s International Development Research Centre (IDRC), made headlines around the world earlier this year. The controversial study determined that this “global scourge” was better described as a global pricing problem: high prices for media goods, combined with low incomes and cheap digital technologies. The report underscored that attempts to police piracy aren’t working and that, in some cases, global enforcement has led to unintended negative socio-economic consequences.

In a panel discussion at IDRC on June 3, three internationally renowned experts will discuss the implications of media piracy for the global economy. Media Piracy in Emerging Economies editor Joe Karaganis, from the American Assembly at Columbia University, and one of the researchers, Ronaldo Lemos, from Brazil’s Center for Technology and Society at the Fundação Getúlio Vargas School of Law (who will appear via live stream), will be joined by technology law expert Michael Geist, from the University of Ottawa, to debate the issues as they relate to Canada and the world.

Cleaning dirty water

Two news items about cleaning dirty water and the Canadian nanotech scene in two days! First, I got news of a Canada-China-India-Israel Roundtable on Sustainable Water Management via Nano- and Emerging Technologies held February 22-23, 2011 in Edmonton, Alberta. [Note: The information about the participant countries is directly from the ISTP website and there is no mention of the US as there is in the following article. This may be due to a late entrance to the event.] From the Feb. 22, 2011 article by Dave Cooper in the Vancouver Sun,

Canada joined hands with four other nations Tuesday in a partnership aimed at harnessing the potential of nanotechnology to improving the world’s water supply.

“Applying advanced technology to the problems of water is a serious issue. This is not a sideshow, it is a fundamental issue,” said Henri Rothschild, CEO of federally backed International Science and Technology Partnerships (ISTP) Canada.

The goal of the participants from Canada, the U.S. [?], China, India and Israel is to discuss “the real opportunities to address these challenges by pooling resources and expertise,” he said, in a spectrum from drinking and waste water to desalinization.

… with plenty of local water research underway to deal with the oilsands, funded by industry and governments, the region is now internationally recognized for its water expertise. “There are a lot of scientists and engineers here who know the subject. It’s leading edge and dealing with some very hard issues,” Rothschild said. “With this roundtable, we are trying to break new ground and create something that takes it to another level, and have it based here in Canada. This is one model under discussion,” he added.

There’s more information about the event on the ISTP roundtable wepage and, for those who are curious about the ISTP itself, here’s a description from their Who We Are page,

STPCanada was incorporated as a not-for-profit organization with the primary objective of strengthening Canada’s science and technology (S&T), business to business relations and ultimately overall economic, trade and political relations. ISTPCanada was selected by the Government of Canada, through the Department of Foreign Affairs and International Trade, to deliver the India, China and Brazil elements of its International Science and Technology Partnerships Program (ISTPP). Reflecting that bilateral S&T agreements are already in place with India and China, funding for these two countries was provided to ISTPCanada in April 2007, with additional funding for Brazil expected in 2008/2009 on completion of a similar bilateral agreement.

I do see the flag for the State of California on the page but it’s  not mentioned as a member of the ISTP. Perhaps they haven’t had time to update the site or they’re not sure how to add the information given that the other members are countries. Also, Brazil which is a member of the ISTP was not at the roundtable.

Getting back to the water, I had no idea the Edmonton region was internationally recognized for its expertise in water.  Meanwhile on the other side of the country, researchers from McGill University have developed a new and inexpensive way to filter water in case of emergencies. From the Feb. 23, 2011 news release,

Disasters such as floods, tsunamis, and earthquakes often result in the spread of diseases like gastroenteritis, giardiasis and even cholera because of an immediate shortage of clean drinking water. Now, chemistry researchers at McGill University have taken a key step towards making a cheap, portable, paper-based filter coated with silver nanoparticles to be used in these emergency settings.

“Silver has been used to clean water for a very long time. The Greeks and Romans kept their water in silver jugs,” says Prof. Derek Gray, from McGill’s Department of Chemistry. But though silver is used to get rid of bacteria in a variety of settings, from bandages to antibacterial socks, no one has used it systematically to clean water before. “It’s because it seems too simple,” affirms Gray.

Prof. Gray’s team, which included graduate student Theresa Dankovich, coated thick (0.5mm) hand-sized sheets of an absorbent porous paper with silver nanoparticles and then poured live bacteria through it. “Viewed in an electron microscope, the paper looks as though there are silver polka dots all over,” says Dankovich, “and the neat thing is that the silver nanoparticles stay on the paper even when the contaminated water goes through.” The results were definitive. Even when the paper contains a small quantity of silver (5.9 mg of silver per dry gram of paper), the filter is able to kill nearly all the bacteria and produce water that meets the standards set by the American Environmental Protection Agency (EPA).

The filter is not envisaged as a routine water purification system, but as a way of providing rapid small-scale assistance in emergency settings. “It works well in the lab,” says Gray, “now we need to improve it and test it in the field.”

This story reminds me of an Aug. 18, 2010  news article by Lin Edwards on physorg.com about ‘nano’ tea bags (excerpted from the article),

Scientists in South Africa have come up with a novel way of purifying water on a small scale using a sachet rather like a tea bag, but instead of imparting flavor to the water, the bag absorbs toxins, filters out and kills bacteria, and cleans the water.

The bag, which fits into the neck of an ordinary water bottle, was developed by scientists at Stellenbosch University in South Africa to help communities with no water purification facilities to clean their water. The bags are made of inexpensive tea bag material but instead of containing tea they contain nano-scale antimicrobial fibers that filter out contaminants and microbes, and granules of activated carbon that kill the bacteria. The nano-fibers are about one hundredth the width of a human hair.

According to researcher Marelize Botes, one sachet can clean a liter of the dirtiest water to about the same water quality of bottled water. Once the bag has been used it is discarded and a new bag is fitted in the neck of the bottle. The discarded bags have no environmental impact as they disintegrate in only a few days and the materials are not toxic to humans.

It’s hard to tell how closely related the research and initiatives are despite the fact that they’re all talking about ‘dirty water’. What I mean is that the water being discussed in the Dave Cooper article is industrial water recycled from sewage and waste, while the McGill researchers and the South African researchers are focused on drinking water that has been contaminated.
