Indoor air quality impacts of an improved wood stove in Ghana and an ethanol stove in Ethiopia, IN: Energy for Sustainable Development, In Press, Corrected Proof, Available online 24 May 2009, ISSN 0973-0826, DOI: 10.1016/j.esd.2009.04.003.

This study was undertaken to assess the potential of two types of improved cookstoves to reduce indoor air pollution in African homes. An ethanol stove, the CleanCook, was tested in three locations in Ethiopia: the city of Addis Ababa and the Bonga and Kebribeyah Refugee Camps, while a wood-burning rocket stove, the Gyapa, was evaluated in Accra, Ghana.

In both countries, kitchen concentrations of PM2.5 and CO, the two pollutants responsible for the bulk of the ill-health associated with indoor smoke, were monitored in a before and after study design without controls. Baseline (`before’) measurements were made in households using a traditional stove or open fire. `After’ measurements were performed in the same households, once the improved stove had been introduced. PM2.5 was measured using UCB Particle Monitors, which have photoelectric detectors. CO was measured with Onset HOBO Loggers. In Ghana and Kebribeyah Camp, CO was also measured with Gastec diffusion tubes.

In Ghana, average 24-hour PM2.5 concentrations decreased 52% from 650 [mu]g/m3 in the ‘before’ phase to 320 [mu]g/m3 in the ‘after’ phase (p = 0.00), and average 24-hour kitchen CO concentrations decreased 40% from 12.3 ppm to 7.4 ppm (p = 0.01). Including all three subgroups in Ethiopia, average PM2.5 concentrations decreased 84% from 1 250 [mu]g/m3 to 200 [mu]g/m3 (p = 0.00) and average CO concentrations decreased 76% from 38.9 ppm to 9.2 ppm (p = 0.00). 24-hour average CO levels in households using both the Gyapa and CleanCook stoves met, or nearly met, the World Health Organization (WHO) 8-hour Air Quality Guideline. PM2.5 concentrations were well above both the WHO 24-hour Guideline and Interim Targets.

Therefore, despite the significant improvements associated with both of these stoves, further changes in stove or fuel type or household fuel mixing patterns would be required to bring PM to levels that are not considered harmful to health.

Solar cooking in the urban households of Ouagadougou

Adapting to an innovation: Solar cooking in the urban households of Ouagadougou (Burkina Faso), IN: Physics and Chemistry of the Earth, Parts A/B/C, Volume 34, Issues 1-2, Sustainable Water Solutions, 2009, Pages 65-71, ISSN 1474-7065, DOI: 10.1016/j.pce.2008.03.006.

Most households in Sub-Saharan Africa rely on wood as primary energy source. The availability of wood is decreasing and deforestation is a major ecological problem in Sub-Saharan Africa. The scarcity of wood is demanding for a sustainable solution. The sun seems to provide a good alternative. Solar energy is free, without unhealthy smoke or chances to burns. The idea of using solar energy for cooking is not new: many different techniques have already been tested. Most variants are expensive, and therefore not available for most families in Sub-Saharan Africa. A cheap solar cooking device is the CooKit, a cardboard panel cooker covered with aluminium foil.

In the adaptation to the CooKit, as to all innovations, it is important that the users are convinced of the advantages. An important step in the adaptation process is learning how to use the cooking device; the best way to do this is by home practice. Monitoring and evaluating the real use is needed, for it is interesting to know if the CooKit is actually used, and also to find out how women have implemented the new technique in their kitchens.

In 2005, the SUPO foundation started a project in Burkina Faso: Programme Energie Solaire Grand-Ouaga (PESGO). The aim of PESGO is to introduce the CooKit in the urban households in Ouagadougou by providing training sessions and home assistance. In this paper, a mid-term review on this small-scale cooking project is presented. The possibilities and challenges of solar cooking are outlined, taking the urban context of Ouagadougou in account. In PESGO, dependence on weather conditions is found to be one of the challenges: if sunrays are blocked by clouds or dust in the air, the cooking will be slowed down. The CooKit cannot replace firewood entirely, and a complementary element has to be found. SUPO is exploring the use of Jatropha oil as a complement to the CooKit. The Jatropha plant is drought tolerant and its fruits contain oil which can be used as fuel substitute. Further research on its use is interesting, because the combination of the CooKit and Jatropha oil seems to have high potential in the kitchens of West-Africa.

World Bank – New Urban Development Program Promotes Ecologically Sustainable and Economically Viable Cities

Singapore—June 26, 2009—The World Bank today launched a new urban development program that supports cities in developing countries in their move towards greater ecological and economic sustainability.

Called Eco2 Cities – Ecological Cities as Economic Cities, the program recognizes that successful cities create economic value and opportunities for their citizens in an inclusive, sustainable and resource efficient way, while also protecting and nurturing the local ecology and global public goods, for future generations.

A three-part book on the Eco2 Cities Program presents the program’s analytical and operational framework along with profiles of effective and practical methods and tools. The next step is to put the framework into action in a first set of cities.

Launching the Eco2 program at a seminar in Singapore on “Liveable Cities in Asia”, the World Bank’s Hiroaki Suzuki – team leader of the Eco2 Cities program – said cities like Curitiba in Brazil, Stockholm in Sweden, Singapore, and Yokohama in Japan have demonstrated that they can greatly enhance their resource efficiency while decreasing pollution and unnecessary waste.

Eco2 Cities co-team leader, Arish Dastur said many cities have found imaginative and practical solutions even with limited budgets. “Sustainable planning is an investment in the future of a city’s economy and welfare,” he said. “The Eco2 Cities program is designed to enable cities in developing countries to put the theory into practice.”

Developed collaboratively by an international team of practitioners and experts from the urban, transport, energy, water and waste management sectors – the Eco2 program is based on real experiences, challenges and lessons learnt from cities in the developed and developing world. The program is building strong linkages with best practice cities like Curitiba, Singapore, Stockholm and Yokohama.

Microinsurance for the poor

Source: Reuters- FEATURE-Microinsurance industry sees profits from the poor

Indonesia – By Sunanda Creagh

JAKARTA, June 25 (Reuters) – Slum-dweller Krustin bin Juri lost everything when floodwaters swept through his home and shop on the banks of Jakarta’s filthy Ciliwung river two years ago.

But when the next flood hits, and it will because Jakarta sees frequent floods in the rainy season, bin Juri may have a modicum of protection thanks to a low-cost insurance policy that he purchased this month.

He is among millions of the world’s poor who are covered for natural disasters by cheap insurance, or microinsurance, as commercial firms recognise that insuring the poor is not just good public relations but also profitable.

“Interest in microinsurance has been exploding throughout the world,” said Craig Thorburn, a senior insurance specialist at the World Bank who has developed microinsurance programmes and who advises countries on insurance market development.

“New projects and proposals are being developed in more and more countries. Government policy-makers are reviewing their regulations and the microinsurance sector does not appear to have been slowed by the crisis.”

Microinsurance began as a form of charity in the 1990s, when the International Labour Organisation began experimenting with super-cheap insurance policies, said Michael McCord, president of the U.S.-based MicroInsurance Centre who recently discussed the topic with officials at Indonesia’s central bank.

In 1995, McCord said he developed an entirely commercial microinsurance product backed by insurer AIG, with a view to selling it through a microfinance institute in Uganda.

“This example showed that commercial microinsurance is possible and became the demonstration model that helped other commercial insurers recognise the low-income market as viable,” he said.

Within a decade, AIG’s Ugandan business covered about 1.6 million lives, and microinsurance premiums accounted for nearly 17 percent of its Ugandan unit’s profits.

Today, a $1,000 life insurance policy sells for just $1 a year in Uganda, McCord said, making it affordable to the poor. He estimates that about 135 million low-income people worldwide are now covered by cheap insurance, up from 78 million two years ago.

Investors are seeing potential in what could be a multi-billion dollar industry. The Leapfrog Financial Inclusion Fund announced last week that it had raised $44 million for what it said was the world’s first microinsurance fund.

“The world desperately needs market-based solutions to poverty that draw in major financial investors by offering fair but competitive returns,” said Dr. Andrew Kuper, President and Founder of LeapFrog, a Luxembourg-based fund.

“Microinsurance is both profitable and scalable,” he was quoted as saying on the fund’s website. The fund will invest in India, Pakistan, South Africa, Ghana and Kenya, it added.

MIXED SUCCESS

Some governments have taken a more active role in promoting such insurance schemes to the poor. For example in India, it is compulsory for insurer firms to offer a microinsurance product, though the results have been mixed.

In practice, only about a third of India’s insurance firms offer such products, said Rupalee Ruchismita, founder of the Centre for Insurance and Risk Management in India, which works with insurers and microfinance firms to develop livestock, health, weather, and catastrophe insurance plans.

“Most insurance firms are doing it simply to meet targets or to be in the good books of the regulators, and their argument is that it is very difficult to reach the intended audience,” she said.

Insurance experts, including Ruchismita and McCord, said such microinsurance schemes tend to be more successful when a community-based organisation works in partnership with a private insurer, as both have strengths in different areas.

For insurers, the sheer number of potential customers in the low-income bracket makes this an attractive market.

“About 80 percent of the world population live in emerging markets but they account for only 22 percent of global GDP and 9 percent of global premiums,” said Kua Ka Hin, Munich Re’s chief executive for Singapore and Southeast Asia.

“These emerging markets still offer huge potential; they have got the large numbers which underline the principle of insurance.”

Kua says Munich Re is looking at microinsurance products in Asia covering earthquakes, typhoons and even loss of income for businesses forced to close because of a flu, or H1N1, pandemic.

FLOOD-PRONE JAKARTA

Last month, Munich Re began a trial of the world’s first flood microinsurance policy in flood-prone central Jakarta.

Residents in Manggarai district pay 50,000 rupiah ($4.88) for a flood “cash card” that can be cashed in for 250,000 rupiah if floodwater levels rise to or above 9.5 metres at the Manggarai Water Gate, which is 2 metres above normal levels.

So far only 50 policies have been sold, partly because the insurance only covers the very worst floods, not the recurrent knee-high flooding that can still ruin homes and possessions.

“People say 950 cm is too high and it’s unlikely to happen. Also, the payout, they said, is too small,” said Francis Purwanta, a spokesman for Munich Re’s local partner, Asuransi Wahana Tata, which sells the policies, pays out claims, and is then reimbursed by Munich Re.

“So we try to explain that it has happened before, at least three times in five years,” said Purwanta.

The idea of making a profit off the very poorest members of society is also controversial. Yet supporters say it is necessary if insurance companies are to back such policies.

“Companies can and should make profits of the low-income market. This is the only way we will get commecial insurers in the market,” said McCord, who adds that non-profit organisations working alone rarely have the technical expertise to calculate the risks and then design an effective insurance program.

“A commercial approach is what’s needed here, across the board. But what helps a lot is using institutions that people trust to deliver the product.”

However, some critics, such as Wardah Hafidz, from the Indonesian non-government organisation Urban Poor Consortium, suggest that governments are evading their responsibilities by expecting poor people to take out private insurance policies.

“The government should be giving protection from disasters to these people instead of assisting private business to target poor people to sell them their products,” she said.

The argument is less philosophical for flood victims such as Bin Juri who knows what it’s like to see his precious possessions washed away and is well aware that the 250,000 rupiah insurance policy he holds would be inadequate to cover his losses if another flood struck his home.

“That alone cost 90,000 rupiah,” he said, pointing to a large cooking pot at his feet. “But it’s some money at least.” ($1=10080 Rupiah) (Additional reporting by Rina Chandran in Mumbai; Editing by Sara Webb and Megan Goldin)

Uganda – Water Project Aims for 100 Percent Access in Urban Areas

June 22, 2009 envhealth@usaid 1 comment

ugandaDeveloping countries aim to cut the proportion of people without safe drinking water in half by the year 2015, as stipulated by the United Nation’s Millennium Goals. Uganda has set a more ambitious target of 100 percent water access for its urban citizens as part of its National Poverty Eradication Action Plan. The country has launched a “pay-as-you-drink” public water project to pave the way.

With her baby strapped to one hip and a jerry can to the other, Aisha Nakawesa used to trek several miles from her home in the Ndeeba district of Kampala to get her family water. Once she reached the water point, she would pay eight cents to fill a 20 liter jerry can with water. Now, Nakawesa says she can fill six cans for the same price by inserting a token into a metal water unit right next to her home.

It is called a pre-paid water meter and this past year Uganda’s National Water and Sewerage Corporation installed 400 of them in the impoverished Ndeeba and Kisyeni sections of Uganda’s capital Kampala. The water points serve around 130,000 residents, a number that is expected to quadruple within the next year in Kampala with the launch of a World Bank funded extension of the project.

Residents pay standard rates directly to the government water operator each time they fill-up says Jon Bosco-Otema, Urban Pro-Poor manager at the National Water and Sewerage Corporation. “National water in the past used to bill customers at the end of the month and you don’t know how much you have consumed, don’t know how much you should prepare. But, with pre-paid meters you manage yout account and also pay-as-you-drink,” he said.

This is the first step in Uganda’s official pledge to make water access available in 100 percent of urban areas by 2015.

Several organizations warn the prepaid system can be abused. They cite Namibia where private operators installed prepaid meters that charge prohibitive costs to the poor. This arguably limits full access to water which is designated as a human right under Uganda’s constitution.

Uganda’s Pre-Paid Meter Project Manager Bosco-Otema responds that Uganda’s system is fully regulated by the government and the minimal amount the poor do pay for the water saves them money in unnecessary health costs associated with contaminated water. “Clean and portable water is very important in the lives of the urban poor. Almost 40 percent of diseases are water related and as results like diarrhea, dysentery, cholera – all this can be avoided by just having clean water,” he said.

Early next month governmental agencies from Tanzania and Kenya are scheduled to visit Uganda to discuss the expansion of prepaid meters across East Africa.

South Africa – “Naming and shaming” businesses for illegal dumping

dumpingBUFFALO City Municipality has blamed big business as the main culprits for illegal dumping and has embarked on a campaign to “ name and shame” them.

This week officials from the city did a routine inspection of an illegal dumpsite in Umtiza Nature Reserve, where they discovered that a furniture company in Beacon Bay, Wetherlys, had been dumping rubbish illegally.

“Our senior managers randomly, on an irregular basis, accompany field personnel in inspecting illegal dumping hot spots and areas that are prone to illegal dumping,” BCM spokesperson Samkelo Ngwenya said.

He said on one of the dumps were magazines, wrappings, invoices and catalogues from Wetherlys.

“The addresses point to the business being situated in Beacon Bay, where we ordered the business to clear the area within a specific period as per our bylaws.

“It is very disturbing to find organised businesses, who are in a position to access proper information and know better, being behind such acts,” said Ngwenya.

Wetherlys regional manager Jean Pretorius yesterday said he was not aware of the illegal dumping by some of his employees, but would attend to the matter. He said it was “absolutely unacceptable” that refuse was being dumped at a nature reserve, and ordered that it be taken to a legal dumpsite.

“On the Buffalo Pass we found out there is a lot of dumping taking place, with the main affected areas inside the premises of the Umtiza Nature Reserve,” said Ngwenya. “This is the same area that we had found letters from the Post Office.”

In December the Post Office was found responsible for dumping in the same area. The Post Office apologised and cleaned up its mess.

“As the reserve is not under the maintenance of the city, we had to engage with them. We discovered that the fence was broken and that dumpers were using these to break into and dump in the three large areas inside.

“We have since advised the reserve to fix the fence and beef up security at their gates so as to monitor and search cars. We then instructed them to clear the dumps,” said Ngwenya.

He said the city also found a garden waste refuse dump.

“It must be noted that we have a legal garden refuse dumpsite in West Bank that processes garden waste for free,” said Ngwenya.

Although the main transgressors, BCM said, businesses were not the only ones to blame.

“On the Mdantsane Access Road we have had challenges, especially around informal settlements, where people throw away trash.

“Three weeks ago we undertook a massive cleaning and awareness operation where we cleared areas along the road banks.

“Judging by the state of the areas that we cleaned, these efforts seem to have fallen on deaf ears,” said Ngwenya.

Official dumping sites in the city are:
- Stoney Drift garden transfer station (Amalinda);
- IDZ garden transfer station (West Bank);
- Beacon Bay garden transfer station (Beacon Bay);
- Second Creek general waste site (Parkside); and
- Round Hill general waste site (Berlin).

E. coli Strains in Urban Pigeons in Brazil

Curr Microbiol. 2009 Jun 6.

Diarrheagenic Escherichia coli Strains Recovered from Urban Pigeons (Columba livia) in Brazil and Their Antimicrobial Susceptibility Patterns, by Silva VL, Nicoli JR, Nascimento TC, Diniz CG.

Laboratory of Bacterial Physiology and Molecular Genetics, Department of Parasitology, Microbiology and Immunology, Institute of Biological Sciences, Federal University of Juiz de Fora, Juiz de Fora, MG, 36036-900, Brazil.

Urban pigeons (Columba livia) come into close contact with humans and animals, and may contribute to the spread of infectious agents. These may include human pathogens such as diarrheagenic Escherichia coli strains, which are able to survive in pigeon feces, thus creating potential for human exposure and infection. Our objectives were to determine the occurrence of diarrheagenic E. coli strains in fresh feces from urban pigeons and their drug susceptibility patterns.

E. coli strains were isolated from 100 fresh feces samples and presumptive phenotypic species identification was carried out, confirmed by amplification of specific 16S ribosomal RNA encoding DNA. Multiplex PCR was performed to characterize pathogenic strains. Drug susceptibility patterns were determined by the agar dilution method.

Enteroinvasive E. coli, Shiga toxin-producing E. coli, enteropathogenic E. coli, and enterotoxigenic E. coli were detected at an overall rate of 12.1%. Among the isolated E. coli strains, 62.1% were susceptible to all tested drugs, whereas 37.9% were resistant to at least one of the antimicrobials tested. Amikacin was the less effective drug (36.8% resistance), followed by ampicillin (7.8%). No resistance was detected to gentamicin, ceftriaxone, and ceftazidime and almost all the isolates were susceptible to ampicillin-sulbactam (98.4%), levofloxacin (97.8%), and trimethoprim-sulfametoxazole (96.1%).

Since these pigeons may harbor multidrug-resistant pathogens, their presence in an urban environment could be an important component of infection spread, with impact on public health.

Lebanon – Effect of Women’s Perceptions and Household Practices on Children’s Waterborne Illness

Ecohealth. 2009 Jun 6.

Effect of Women’s Perceptions and Household Practices on Children’s Waterborne Illness in a Low Income Community. by El Azar GE, Habib RR, Mahfoud Z, El-Fadel M, Zurayk R, Jurdi M, Nuwayhid I.

An ecosystem approach to human health was adopted in a community-based study carried out in Bebnine, an underserved town in Lebanon. The objective of the study is to examine the association between women’s household practices and diarrhea among children in a setting where contaminated drinking water and intestinal diseases are common.

A total of 280 women were randomly selected and interviewed using a structured questionnaire. Data were collected on 712 children between the ages of 6 and 14. The study instrument included determinants of diarrhea such as sociodemographic characteristics, water, sanitation, hygiene practices, gender variables, and behavioral risk factors. Multivariate regression analysis was employed to examine the association between water handling practices and diarrhea.

The prevalence of diarrhea is 5%. Female children are more likely to suffer from diarrhea than male children (OR = 2.58; 95% CI: 1.19-5.62). Treatment of drinking water at the household level and the use of drinking water for cooking and the preparation of hot beverages are protective against diarrhea (OR = 0.15; 95% CI: 0.03-0.65). Female caretakers’ behaviors such as daily bathing and seeking medical care at times of illness are protective against diarrhea in children.

The findings suggest that diarrhea is a gendered health problem. Female children, who are generally more involved in household activities than male children, are at higher risk of suffering from diarrhea. Female caretakers’ personal hygiene, household practices, and perceptions of diarrhea are additional risk factors. Intervention activities would be more effective if based on a better understanding of gender roles and household power relations.

India – Urban malaria situation improves

Margao malaria cases on the decline: UHC

MARGAO: Though health officials are clueless about what the malaria scene would be at the end of June – the month of malaria – statistics on malaria cases in Margao and Fatorda have revealed that intensive drives conducted by the Margao urban health centre (UHC) to combat the disease during the past two years has resulted in a considerable decline in the number of cases of the deadly disease.

According to figures presented to TOI by health officer Geeta Kakodkar on Friday, the total number of cases in 2008 were 1107 as compared to 1291 in 2007, while the total number of cases reported till May this year stand at 132. In 2005, the twin towns recorded a spurt in malaria with 1184 cases while in 2006, only 935 cases were reported.

However, according to Kakodkar, the statistics of 2005 and 2006 were obtained from the cases reported at the UHC alone. “From 2007, when I took charge of the UHC, we commenced the procedure of collecting samples from private labs and Hospicio which helped us to get more or less a fair picture on the prevalence of malaria at Margao and Fatorda,” she explained.

Cases of the deadly Plasmodium Falciparum last year showed a downward trend with 222 cases, while in 2007, cases reported were 291. In 2005, it was 134 and in 2006, 193 cases were reported. This year till May, a total of 18 cases of plasmodium falciparum have been reported.

Cases of plasmodium vivax reported last year were 885 as compared to 1000 cases reported in 2007. In 2005, a total of 1044 cases were reported and in 2006 it was 786. This year cases of plasmodium vivax reported till May stand at 114.

Though statistics show a steady decline in the cases of deadly plasmodium falciparum last year, Kakodkar warned that much needs to be done to bring down the figures further considering that plasmodium falciparum is the most dangerous of the serious febrile illness.

Nonetheless, health officials attribute the prevalence of malaria to the unmonitored influx of migrant labourers from malaria prone areas. The city, which has an influx of 600 (according to UHC figures) migrant labourers and over 169 construction sites (21 major), has been literally battling against the disease for the past several years. While Fatorda, KTC area, Mungul, Maddel, Borda and Comba areas face high risk of plasmodium falciparum, some areas of Khareband, Gogol, Housing Board, Malbhat and Aquem are sensitive to the less harmful vivax malaria.

Taking a major step towards combating malaria, the urban health centre, a nodal monitoring and preventing agency, has urged the 26 private laboratories to report cases to the centre. “We started this procedure from July 2007. Since the private sector has 60 to 70% stake in public health, their co-operation can be vital. Our workers collect the data from these labs which help us to take corrective measures,” informed Kakodkar.

IIED – Poverty Lines in Greater Cairo: underestimating and misrepresenting poverty

Sabry, S. (2009). Poverty Lines in Greater Cairo: underestimating and misrepresenting poverty. Human Settlements Working Paper Series: Poverty Reduction in Urban Areas-21. London, IIED. (pdf, 473KB)

This paper engages with the global debate about the meaningfulness, validity and reliability of the poverty-line approach by examining the Egyptian poverty lines in relation to the reality of the lives of the urban poor in Greater Cairo. It reviews Egypt’s various poverty lines, and the data which inform them, and then questions their value in relation to the real costs of some basic living needs in eight of Greater Cairo’s informal areas in 2008. The paper concludes that the incidence of poverty is severely underestimated in Greater Cairo. This is because poverty lines are set too low in relation to the costs of even the most basic of needs, and because the household survey data which inform poverty-line studies under-sample people living in informal settlements, as they are based on census data which under-count the populations of informal areas.
