Vulnerability to Food Insecurity in Urban Slums: Experiences from Nairobi, Kenya. J Urban Health. Dec 2014; 91(6): 1098–1113.

Authors: E. W. Kimani-Murage,corresponding author L. Schofield, F. Wekesah, S. Mohamed, B. Mberu, R. Ettarh, T. Egondi, C. Kyobutungi, and A. Ezeh

This study describes the food security situation among slum residents in Nairobi, with specific focus on vulnerability associated with the 2007/2008 postelection crisis in Kenya. Food security was defined using the Household Food Insecurity Access Scale (HFIAS) criteria. The study found high prevalence of food insecurity; 85 % of the households were food insecure, with 50 % being severely food insecure. Factors associated with food security include level of income, source of livelihood, household size, dependence ratio; illness, perceived insecurity and slum of residence. The qualitative narratives highlighted household vulnerability to food insecurity as commonplace but critical during times of crisis. Respondents indicated that residents in the slums generally eat for bare survival, with little concern for quality. The narratives described heightened vulnerability during the 2007/2008 post election violence in Kenya in the perception of slum residents. Prices of staple foods like maize flour doubled and simultaneously household purchasing power was eroded due to worsened unemployment situation. The use of negative coping strategies to address food insecurity such as reducing the number of meals, reducing food variety and quality, scavenging, and eating street foods was prevalent.

In conclusion, this study describes the deeply intertwined nature of chronic poverty and acute crisis, and the subsequent high levels of food insecurity in urban slum settings. Households are extremely vulnerable to food insecurity; the situation worsening during periods of crisis in the perception of slum residents, engendering frequent use of negative coping strategies. Effective response to addressing vulnerability to household food insecurity among the urban poor should focus on both the underlying vulnerabilities of households due to chronic poverty and added impacts of acute crises.

Informal settlements and a relational view of health in Nairobi, Kenya: sanitation, gender and dignity

Informal settlements and a relational view of health in Nairobi, Kenya: sanitation, gender and dignity. Health Promo Intl, Nov 2014.

Jason Corburn1,* and Irene Karanja2. 1City and Regional Planning, UC Berkeley, 228 Wurster Hall, Berkeley, CA, USA 2Muungano Support Trust, Nairobi, Kenya. E-mail: jcorburn@berkeley.edu

On an urban planet, slums or informal settlements present an increasing challenge for health promotion. The living conditions in complex informal settlements interact with how people navigate through their daily lives and political institutions to shape health inequities. In this article, we suggest that only a relational place-based characterization of informal settlements can accurately capture the forces contributing to existing urban health inequities and inform appropriate and effective health promotion interventions.

We explore our relational framework using household survey, spatial mapping and qualitative focus group data gathered in partnership with residents and non-governmental organizations in the Mathare informal settlement in Nairobi, Kenya. All data interpretation included participation with local residents and organizations. We focus on the inter-relationships between inadequate sanitation and disease, social, economic and human rights for women and girls, who we show are most vulnerable from poor slum infrastructure.

We suggest that this collaborative process results in co-produced insights about the meanings and relationships between infrastructure, security, resilience and health. We conclude that complex informal settlements require relational and context-specific data gathering and analyses to understand the multiple determinants of health and to inform appropriate and effective healthy city interventions.

Infant and child feeding index reflects feeding practices, nutritional status of urban slum children

Infant and child feeding index reflects feeding practices, nutritional status of urban slum children. BMC Pediatr. 2014; 14(1): 290.Published online Nov 30, 2014.

Authors: Neha Lohia and Shobha A Udipi

Background - Infant and child feeding index (ICFI) an age-specific index, can be used to assess child feeding practices. We used the ICFI to assess feeding practices for urban slum children and the association between ICFI and child nutritional status.

Methods - 446 children aged 6 to 24 months from urban slums of Mumbai, India were studied. We used the 24-hour diet recall to study dietary diversity and a food frequency questionnaire for consumption of food groups during the preceding week. ICFI was computed using five components, namely, breastfeeding, use of bottle, dietary diversity score (DDS), food group frequency score (FGFS) and feeding frequency scores (FFS). Weight, height and Mid-Upper Arm Circumference (MUAC) were measured, and z scores were calculated. Association between ICFI scores and nutritional status was examined.

Results - The mean total ICFI score for all was 5.9 ± 1.9. Among the five components, FGFS and FFS differed between children <12 months of age and >12 months and by breast feeding status. In contrast, there were no differences vis-à-vis dietary diversity scores (DDS), breast feeding, and use of bottle. Non-breastfed children had significantly higher DDS scores than did breastfed children. The mean feeding frequency score (FFS) for children <12 months of age was slightly but not significantly lower than scores for children >12 months of age. Mother’s age and child’s age were significant determinants of ICFI. Multivariate analysis indicated that ICFI was significantly associated with Length-for-Age z scores (LAZ) and BMI-for-Age z scores (BAZ). Sensitivity of ICFI was lower than its specificity.

Conclusions - The results of the present study confirmed that the ICFI can be used to collect information on key components of young child feeding practices and be incorporated into public-health programmes. Further, it could be used to determine the influence of complementary feeding practices on nutritional status of children.

A Simple Microbiological Tool to Evaluate the Effect of Environmental Health Interventions on Hand Contamination

9 December 2014 14:03 (America/New_York)

A Simple Microbiological Tool to Evaluate the Effect of Environmental Health Interventions on Hand Contamination. Int J Environ Res Public Health. Nov 2014; 11(11): 11846–11859.

Authors: Carol Devamani, Guy Norman and Wolf-Peter Schmidt

The effects of interventions such as sanitation or hand hygiene on hand contamination are difficult to evaluate. We explored the ability of a simple microbiological test to: (1) detect recontamination after handwashing; (2) reflect risk factors for microbial contamination and (3) be applicable to large populations. The study was done in rural Andhra Pradesh, India, and Maputo, Mozambique. Participants placed all 10 fingertips on a chromogenic agar that stains Enterococcus spp. and E. coli spp. Outcomes were the number of colonies and the number of fingertips with colonies. In the recontamination study, participants were randomised to handwashing with soap and no handwashing, and tested at 30 min intervals afterwards. In two cross sectional studies, risk factors for hand contamination were explored. Recontamination of hands after washing with soap was fast, with baseline levels reached after 1 h. Child care was associated with higher Enterococcus spp. counts, whereas agricultural activities increased E. coli spp. counts. Food preparation was associated with higher counts for both organisms. In Maputo, counts were not strongly associated with water access, latrine type, education or diarrhoea. The method seems unsuitable for the evaluation of handwashing promotion. It may reflect immediately preceding risk practices but not household-level risk factors.

Place and Child Health: The Interaction of Population Density and Sanitation in Developing Countries

Place and Child Health: The Interaction of Population Density and Sanitation in Developing Countries, 2014. World Bank.

Authors: Payal Hathi, Sabrina Haque, Lovey Pant, Diane Coffey Dean Spears

This paper assesses whether the importance of dense settlement for child mortality and child height is moderated by exposure to local sanitation behavior. Is open defecation, without a toilet or latrine, worse for infant mortality and child height where population density is greater? Is poor sanitation an important mechanism by which population density influences health outcomes? The paper uses newly assembled data sets to present two complementary analyses, which represent different points in a trade-off between external and internal validity. The first analysis concentrates on external validity by studying infant mortality and child height in a large, international child-level data set of 172 Demographic and Health Surveys, matched to census population density data for 1,800 subnational regions. The second analysis concentrates on internal validityby studying child height in Bangladeshi districts, witha new data set constructed with Geographic Information System techniques, and controls for fixed effects at a high level of geographic resolution. The paper finds a statistically robust and quantitatively comparable interaction between sanitation and population density with both approaches:open defecation externalities are more important for child health outcomes where people live more closely together.

Authors: Georgia State University, Atlanta, USA

The Urban Health Index (UHI) is a single metric that can be used to measure and map the disparities in health determinants and outcomes in urban areas. This Handbook is primarily intended for those who want to calculate the UHI for a particular geographic area of interest.What is the Urban Health Index?The UHI provides a flexible approach to selection, amalgamation, and presentation of health data. Its purpose is to furnish visual, graphical, and statistical insight into various health indicators and, health determinants within particular geographic boundaries and health disparities with a focus on capturing intra-urban health disparities. The UHI may be used by public health workers, evaluators, statisticians, program managers, academic researchers, and decision makers to examine the current status of urban areas, to assess change and the effect of program interventions, and to plan for urban improvements.

Various new planning methodologies have been developed and applied, embodying a shift in thinking on sanitation issues. The experiences from these planning approaches are incorporated into the Sanitation21 planning framework, which epitomizes the new generation of sanitation master planning. Unlike conventional master planning approaches, these planning approaches consider a wider range of aspects of sanitation that are not specifically related to infrastructure. These relate to issues of poverty, inequity, land ownership, environmental concerns, or the wider political economy.

Towards systemic change in urban sanitation

25 November 2014 10:52 (America/New_York)

Towards systemic change in urban sanitation, 2014.

Authors: Galli, G., Nothomb, C., and Baetings, E. IRC.

Failing systems, caused by fragmented, disorganised and uncoordinated government leadership, coupled with the ineffective application of already-scarce resources, mark the state of urban sanitation in most low-and middle-income countries. The two most critical results are that it impacts very negatively on the health and wellbeing of the urban poor and on all aspects of the intended or desired sustainability of sanitation systems.

Against this background, this working paper outlines a ‘whole-system approach’ to urban sanitation by shifting the focus from building infrastructure or a project-driven implementation approach to providing and maintaining equitable and environmentally friendly services, championed and supported by the government and with sufficient resources allocated to ensure sustainability.

This working paper proposes a step-by-step approach to unravel and tackle the very complex circumstances surrounding the need to provide sanitation in urban areas, particularly in densely populated areas and to the less affluent sectors of society.

Gender variations in access, choice to use and cleaning of shared latrines; experiences from Kampala Slums, Uganda

25 November 2014 10:47 (America/New_York)

Gender variations in access, choice to use and cleaning of shared latrines; experiences from Kampala Slums, Uganda. BMC Public Health 2014, 14:1180

Authors: Japheth Kwiringira, Peter Atekyereza, Charles Niwagaba and Isabel Günther

Background - Sanitation is one of the most intimate issues that affect women, especially in slums of developing countries. There are few studies that have paid attention to the gender variations in access, choice to use and cleaning of shared latrines in slums. Methods - This paper draws on qualitative data from a cross sectional study conducted between 2012 and 2013 in six slums of Kampala City, Uganda. The study involved both women and men. Data were collected from 12 Focus Group Discussions (FGDs), 15 Key informant interviews; community transects and photographs of shared latrines. Results - Location of a shared latrine facility, distance, filthy, narrow and irregular paths; the time when a facility is visited (day or night), privacy and steep inclines were gender ‘filters’ to accessing shared latrines. A full latrine pit was more likely to inhibit access to and choice of a facility for women than men. Results indicate that the available coping mechanisms turned out to be gendered, with fewer options available for women than men. On the whole, women sought for privacy, easy reach, self-respect and esteem, cleanliness and privacy than men. While men like women also wanted clean facilities for use; they (men) were not keen on cleaning these facilities. The cleaning of shared latrines was seen by both women and men as a role for women. Conclusion - The presence of sanitation facilities as the first step in the access, choice, use, and cleaning by both women and men has distinct motivations and limitations along gender lines. The study confirms that the use and cleaning of latrines is regulated by gender in daily living. Using a latrine for women was much more than relieving oneself: it involved security, intimacy and and health concerns.

 

 

Sanitation can eliminate slums in less than a generation

Author: Magda Mis

Investing in water and sanitation could eradicate urban poverty and eliminate slums in less than a generation, said a study published on Thursday.

Almost 1 billion people, most of them in South Asia and Africa, live in slums without access to basic services like clean water and improved toilets.

Providing water and sanitation to those impoverished areas is necessary to drive economic development and can be done within decades, a study by international charity Water Aid said.

“Sanitation doesn’t come once prosperity comes – it is a driver of prosperity,” Barbara Frost, chief executive of Water Aid told the Thomson Reuters Foundation on the sidelines of a water summit in London.

Singapore and South Korea, prosperous countries that struggled with open sewers just a few decades ago, now provide good water and sanitation services to their population.

Such states achieved it through strong political leadership, campaigns like the “Keep Singapore clean” initiative, and by making investment in water and sanitation a priority, according to the study.

“The focus (needs to be) on moving from slum conditions, like open sewers and stinking rivers, to a modern city and this is what they have achieved in Singapore,” said Frost.

Even though most slums are mushrooming around cities in developing countries, national wealth should not be a condition for water and sanitation investments, the study said.

In the 1960s, when South Korea started to work on universal access to these services, its per capita GDP was lower than that of many countries in sub-Saharan Africa.

Frost said Rwanda is a good example of how, when sanitation is made a priority, progress can be achieved quickly.

“(Rwanda is) making enormous progress…and that’s partially(thanks to) strong leadership,” said Frost.

The country managed to deliver sanitation services to an additional 30 percent of its population in just a decade.

Globally, more than 700 million people do not have access to clean water and 2.5 billion live without improved sanitation.

The United Nations is due to set new sustainable development objectives in 2015 with a global target of eradicating extreme poverty by 2030.

“If the goal of eradicating extreme poverty by 2030 is to be realised, it’s going to be essential that investment is made in water and sanitation,” Frost said.

“Unless there is universal access to (those) basic services, extreme poverty can’t be eradicated.” (Reporting By Magdalena Mis; Editing by Maria Caspani)

 

Ebola in urban slums: the elephant in the room

25 November 2014 10:33 (America/New_York)

Ebola in urban slums: the elephant in the room. The Lancet Global Health, Early Online Publication, 30 October 2014

Authors: Robert E Snyder, Mariel A Marlow, Lee W Riley

A host of factors has been cited as causes of the current Ebola virus disease (EVD) epidemic in west Africa: local cultural practices, poverty, inadequate health infrastructure, and the region’s recent strife-filled history. These factors alone, however, cannot completely explain the epidemic’s uncontrolled nature. There is an “elephant in the room” in the international discourse concerning this epidemic: urban informal human settlements or slums.

The UN defines slums as settlements with inadequate access to safe water, sanitation, and other infrastructure; poor structural housing quality; overcrowding; and insecure residential status.1 These conditions are the perfect breeding ground for EVD. Previously reported outbreaks of EVD occurred in rural and geographically isolated communities.2—6 The presumed introduction of the virus to the slums of Kenema and Freetown in Sierra Leone has undoubtedly augmented its spread.7 Sierra Leone is urbanising at a rate of 3% each year, and in 2005 more than 97% of its urban population lived in slums.8

The West Point slum in Monrovia, Liberia, has been a flashpoint for that country’s epidemic. The community’s poor health infrastructure, lack of health education, and inadequate government-enforced quarantine have all contributed to the disease’s spread. WHO has reported that the bodies of West Point EVD victims were being thrown into an adjacent river in a desperate attempt to stem the disease and deal with the overwhelming death toll.9 This inhumane situation is another simple means for the disease’s transmission to new areas.

Slum residents can be a highly mobile population. Limited economic opportunities force slum residents to migrate, clandestinely and often illegally, to new cities and countries. This type of migration subverts anti-EVD screening measures and presents an imminent threat to other informal communities and the rest of the world.

The primary factor contributing to slum dwellers’ disproportionate disease burden—their invisibility and neglect—also makes them an ideal vehicle for the epidemic. EVD is only the beginning and only one disease; even if we are to control the current epidemic, the future introduction of this and other highly contagious and virulent microbes to and from global slums is inevitable. It is not sufficient just to talk about poverty, lack of health-care access, cultural practices, etc. It will be impossible to stem this epidemic and prevent future epidemics of emerging diseases without addressing the underlying structural and socioeconomic determinants of disease unique to slums. Experts and politicians must acknowledge their existence now and divert resources towards improving the conditions of urban slums.

Bangladesh Urban Health Survey 2013: Preliminary Results, October 2014

30 October 2014 12:16 (America/New_York)

Bangladesh Urban Health Survey 2013: Preliminary Results, October 2014.

National Institute of Population Research and Training (NIPORT); MEASURE Evaluation, icddr,b Funded by:
US Agency for International Development, , Bangladesh, Department for International Development (DFID).

Key Findings

Child Mortality

  • During 2009-2013, one in eighteen children in slums dies before reaching the fifth birthday.
  • In slums, U5MR declined by 30% during the last seven years whereas IMR declined by 22%. While child mortality (CM) and neonatal mortality (NN) declined substantially during this period, post-neonatal mortality (PNN) remained largely unchanged.

Child Health

  • More than half of under-five children with symptoms of ARI in slums are taken to a health facility or a medically trained provider for treatment compared to two-thirds in non-slums. However, skilled care seeking for childhood ARI improved only in slums during 2006-2013.
  • Higher proportion of under-five children with ARI receives antibiotics in slums than non-slums in 2013 (47% vs. 40%).

Child Feeding and Nutrition

  • Exclusive breastfeeding of children under six months approached 60 percent both in slums and non-slums, and slightly higher in other urban (66%).  In both slums and non-slums, there has been a substantial increase in exclusive breastfeeding from the 2006 level.
  • Only one in four children of age 6-23 months in slums are fed with proper IYCF practices, which is 40 percent for non-slums.
  • Half of under-five children in slums were stunted (height-for-age below -2SD), which is around one-third for non-slums and other urban areas. Underweight among under-five children in slums (43%) is considerably higher in non-slums (26%) and other urban areas (30%).
  • In the last seven years, there has only been a slight improvement in nutritional status in both slums and non-slums.
  • In all urban domains, overall wasting rate surpassed the WHO specified emergency level (15%). In both slum and non-slum areas, wasting has increased in the last seven years


Ecohealth Approach to Urban Waste Management: Exposure to Environmental Pollutants and Health Risks in Yamoussoukro, Côte d’Ivoire

30 October 2014 12:05 (America/New_York)

Ecohealth Approach to Urban Waste Management: Exposure to Environmental Pollutants and Health Risks in Yamoussoukro, Côte d’Ivoire. Int. J. Environ. Res. Public Health, Oct 2014, 11(10).

Authors: Parfait K. Kouamé, Kouassi Dongo, et al.

We undertook trans-disciplinary research within an Ecohealth approach, comprised of a participatory workshop with stakeholders and mapping of exposure patterns. A total of 492 randomly selected households participated in a cross-sectional survey. Waste deposit sites were characterised and 108 wastewater samples were subjected to laboratory examinations. The physico-chemical parameters of the surface water (temperature, pH, conductivity, potential oxidise reduction, BOD5, COD, dissolved oxygen, nitrates, ammonia and total Kendal nitrogen) did not comply with World Health Organization standards of surface water quality.

Questionnaire results showed that malaria was the most commonly reported disease. Diarrhoea and malaria were associated with poor sanitation. Households having dry latrines had a higher risk of diarrhoea (odds ratio (OR) = 1.8, 95% confidence interval (CI) 1.2–2.7) compared to latrines with septic tanks and also a higher risk for malaria (OR = 1.9, 95% (CI) 1.1–3.3). Our research showed that combining health and environmental assessments enables a deeper understanding of environmental threats and disease burdens linked to poor waste management. Further study should investigate the sanitation strategy aspects that could reduce the environmental and health risks in the study area.

Emerging contaminants in urban groundwater sources in Africa

30 October 2014 11:32 (America/New_York)

Emerging contaminants in urban groundwater sources in Africa. Water Research, Available online 13 August 2014.

Authors: J.P.R. Sorensen, D.J. Lapworth, et al.

Highlights
• First study to do broad screening for emerging contaminants in water in Africa.
• DEET is omnipresent in groundwater.
• Less frequently detected compounds include triclosan, trihalomethanes and pesticides.
• Contaminants were most prevalent in hand-dug wells in low income residential areas.
• Seasonal changes in DEET highlight its mobility and aquifer vulnerability.

The occurrence of emerging organic contaminants within the aquatic environment in Africa is currently unknown. This study provides early insights by characterising a broad range of emerging organic contaminants (n > 1000) in groundwater sources in Kabwe, Zambia. Groundwater samples were obtained during both the dry and wet seasons from a selection of deep boreholes and shallow wells completed within the bedrock and overlying superficial aquifers, respectively. Groundwater sources were distributed across the city to encompass peri-urban, lower cost housing, higher cost housing, and industrial land uses. The insect repellent DEET was ubiquitous within groundwater at concentrations up to 1.8 μg/L. Other compounds (n = 26) were detected in less than 15% of the sources and included the bactericide triclosan (up to 0.03 μg/L), chlorination by-products – trihalomethanes (up to 50 μg/L), and the surfactant 2,4,7,9-tetramethyl-5-decyne-4,7-diol (up to 0.6 μg/L). Emerging contaminants were most prevalent in shallow wells sited in low cost housing areas. This is attributed to localised vulnerability associated with inadequate well protection, sanitation, and household waste disposal.

The five-fold increase in median DEET concentration following the onset of the seasonal rains highlights that more mobile compounds can rapidly migrate from the surface to the aquifer suggesting the aquifer is more vulnerable than previously considered. Furthermore it suggests DEET is potentially useful as a wastewater tracer in Africa. There was a general absence of personal care products, life-style compounds, and pharmaceuticals which are commonly detected in the aquatic environment in the developed world. This perhaps reflects some degree of attenuation within the subsurface, but could also be a result of the current limited use of products containing emerging contaminants by locals due to unaffordability and unavailability. As development and population increases in Africa, it is likely a wider-range of emerging contaminants will be released into the environment.

 

The Limits and Possibilities of Prepaid Water in Urban Africa: Lessons from the Field

The Limits and Possibilities of Prepaid Water in Urban Africa: Lessons from the Field, 2014.

Authors: Chris Heymans, Kathy Eales and Richard Franceys. Water and Sanitation Program.

This study explores the potential of prepaid meters for serving urban poor communities. It provides urban utilities, oversight agencies, and other stakeholders in Africa with a basis for decision-making on the suitability, introduction, and management of such meters. The need for the assessment emerged from prepaid meters.

Of the three applications, prepaid public standpipes seem most likely to enable water utilities to serve poor households better and offset investment and running costs. This capability is contingent on a distribution network with adequate pressure, the existence of convenient credit purchase points, and a strong customer service component to address faults promptly.

This report identifies and discusses key areas in which policy reform, improved regulation, and innovative operational practice could help make the use of prepaid water systems conducive to serving poor people. Key suggestions about the way forward include:

Be clear about the priority: Reaching people without their own connections. Prepaid systems’ core potential is in addressing the fact that many urban Africans still do not have their own water connections and remain outside the reach of subsidy regimes. Prepayment does not offer an obvious answer to these challenges, but some of these systems’ attributes may provide a tool for addressing them in certain circumstances.

 

Running water in India’s cities : a review of five recent public-private partnership initiatives

Running water in India’s cities : a review of five recent public-private partnership initiatives, 2014. World Bank.

Authors: Kacker, Suneetha Dasappa; Ramanujam, SR; Miller, Tracey.

India is home to more than 370 million people in urban areas. Historically, almost all water supply provision has been managed by the public sector through municipal or state-level departments or parastatals. Benchmarking initiatives show that coverage through piped water supply ranges between 55 percent and 89 percent in urban areas. Per capita availability is fairly high, at 90 to 120 liters per day, but no city yet offers continuous water supply. Daily supply averages four hours, with many cities alternating supply every other day.

These challenges occur in a context of weak management systems and little data on existing assets, which makes it difficult to assess investment needs and time lines to improve service levels and operational efficiencies. While investment requirements are likely to be significant, it is recognized that investments alone will not be effective unless the country simultaneously addresses related issues such as complex and fragmented institutions with little accountability; lack of capacity to run utilities efficiently and meet performance standards; weak commercial orientation; interference in utility operations by external entities; and the absence of a regulatory framework focused on customer service and financial sustainability.

Vulnerability to Food Insecurity in Urban Slums: Experiences from Nairobi, Kenya

Vulnerability to Food Insecurity in Urban Slums: Experiences from Nairobi, Kenya. Journal of Urban Health,
August 2014.

Authors: E. W. Kimani-Murage, L. Schofield, F. Wekesah, S. Mohamed, B. Mberu, R. Ettarh, T. Egondi, C. Kyobutungi, A. Ezeh

This study describes the food security situation among slum residents in Nairobi, with specific focus on vulnerability associated with the 2007/2008 post election crisis in Kenya. The study found high prevalence of food insecurity; 85 % of the households were food insecure, with 50 % being severely food insecure. Factors associated with food security include level of income, source of livelihood, household size, dependence ratio; illness, perceived insecurity and slum of residence. The qualitative narratives highlighted household vulnerability to food insecurity as commonplace but critical during times of crisis.

Respondents indicated that residents in the slums generally eat for bare survival, with little concern for quality. The narratives described heightened vulnerability during the 2007/2008 post election violence in Kenya in the perception of slum residents. Prices of staple foods like maize flour doubled and simultaneously household purchasing power was eroded due to worsened unemployment situation. The use of negative coping strategies to address food insecurity such as reducing the number of meals, reducing food variety and quality, scavenging, and eating street foods was prevalent.

In conclusion, this study describes the deeply intertwined nature of chronic poverty and acute crisis, and the subsequent high levels of food insecurity in urban slum settings. Households are extremely vulnerable to food insecurity; the situation worsening during periods of crisis in the perception of slum residents, engendering frequent use of negative coping strategies. Effective response to addressing vulnerability to household food insecurity among the urban poor should focus on both the underlying vulnerabilities of households due to chronic poverty and added impacts of acute crises.

Levels & Trends in Child Mortality: Report 2014

Levels & Trends in Child Mortality: Report 2014. UNICEF.

Substantial global progress has been made inreducing child deaths since 1990. The number ofunder-five deaths worldwide has declined from12.7 (12.5, 12.9)1 million in 1990 to 6.3 (6.1, 6.7)million in 2013. While that translates into around17,000 fewer children dying every day in 2013than in 1990, it still implies the deaths of about17,000 children under age five every day in 2013.

The leading causes of death among childrenunder age five include preterm birth complications (17 percent of under-five deaths),pneumonia (15 percent), intrapartum-relatedcomplications (complications during labour anddelivery; 11 percent), diarrhoea (9 percent) andmalaria (7 percent). Globally, nearly half of under-five deaths are attributable to undernutrition.

The global under-five mortality rate is fallingfaster than at any other time during thepast two decades. The global annual rateof reduction has steadily accelerated since1990–1995—more than tripling from 1.2percent to 4.0 percent in 2005–2013.

Designing the next generation of sanitation businesses

17 September 2014 13:06 (America/New_York)

Designing the next generation of sanitation businesses: a report by HYSTRA for the Toilet Board Coalition, 2014.

Fortunately, a number of market-based models have emerged in both rural and urban areas to address the sanitation crisis. They all serve the Base of the Pyramid in a sustainable manner by offering improved solutions, at a price that the poor are willing and able to pay. In this Report, we analyze two models that combine an aspirational value proposition for low-income families and a strong potential for financial sustainability: projects that facilitate the creation of a local, sanitation market in rural areas and enterprises servicing home mobile toilets in urban areas.

Based on an in-depth analysis of 12 projects representative of these two models, the Report suggests strategies to overcome challenges to sustainability and scale. Finally, the Report explores how these models would benefit from corporate and industrial expertise and resources, opening up opportunities for large corporations to contribute to solving the sanitation crisis.
