Government of India. May 2010.

The National Sample Survey Office (NSSO) has released Report No.534 titled “Some Characteristics of Urban Slums, 2008-09″ based on the survey of urban slums conducted in its 65th round. The field work of the nationwide survey was carried out during July 2008 to June 2009. This report is based on the data collected from 365 notified and 365 non-notified slums found in 4738 surveyed urban blocks.

Some important findings of the survey are given below.

  • About 49 thousand slums were estimated to be in existence in urban India in 2008-09, 24% of them were located along nallahs and drains and 12% along railway lines.
  • About 57% of slums were built on public land, owned mostly by local bodies, state government, etc.
  • In 64% of notified slums, a majority of the dwellings were pucca, the corresponding percentage for the non-notified ones being 50%.
  • For 95% slums, the major source of drinking water was either tap or tubewell.
  • Only 1% notified and 7% non-notified slums did not have electricity connection.
  • About 48% of the slums were usually affected by waterlogging during monsoon – 32% with inside of slum waterlogged as well as approach road to the slum, 7% where the slum was waterlogged but not the approach road, and 9% where only the approach road was waterlogged in the monsoon.
  • The sanitary conditions in the slums in terms of latrine facility during 2008-09 showed considerable improvement since 2002. Latrines with septic tanks (or similar facility) were available in 68% notified and 47% non-notified slums (up from 66% and 35% respectively in 2002). At the other extreme, 10% notified and 20% non-notified slums (down from 17% and 51% in 2002) did not have any latrine facility at all.

Scientists have developed an improved method for controlling container-inhabiting mosquitoes responsible for the transmission of chikungunya and dengue viruses.

New pellet formulations of a chemical that kills mosquito larvae and pupae — Agnique — were used for the first time in combination with another insecticide — Altosid — in laboratory and field tests.  Combined, the two insecticides had a longer-lasting effect than using either one alone.

They were used in a spray to coat water-filled containers where mosquitoes deposit their eggs.

In the laboratory, this provided 80 per cent mosquito control for 60 days, and 95 per cent control for at least 32 days in the field trials, according to the study published in this month’s (May) issue of The American Journal of Tropical Medicine and Hygiene.

The spray’s dual action interfered with mosquitoes’ development as well as the surface tension of the water — preventing larvae and pupae from remaining on the surface to breathe.

Altosid also remained effective after 107 days of a drought simulated in the laboratory, suggesting that it could prevent mosquitoes breeding even when dried-out water containers are refilled after periods of drought.

Co-author of the study Banugopan Kesavaraju, entomologist at US-based Salt Lake City Mosquito Abatement District, told SciDev.Net that “the container mosquitoes like Asian tiger mosquitoes, Aedes albopictus, colonise containers that can hold small quantities of water such as trash cans, cemetery vases and toys, which are more common in urban and suburban areas”.

He said that this makes the use of pesticides difficult in urban areas. Since the combined spray targets all mosquito life stages in the containers, this would permit better long-term mosquito control, he added.

Nuananong Jirakanjanakit, biomedical researcher at Mahidol University, Thailand, said this new method could be a realistic way of tackling mosquitoes and capping the transmission of diseases such as chikungunya and dengue fever.

Chikungunya virus is spread by mosquitoes found in standing water in urban areas. It re-emerged on several islands in the Indian Ocean in 2005, caused an outbreak in India in 2006–07, and was reported in Europe in 2007.

Dengue is now the most rapidly spreading mosquito-borne viral disease in the world (see also Dengue fever surges in Americas). In the absence of an effective drug or vaccine, vector control is the only way to reduce disease transmission.

Theeraphap Chareonviriyaphap, entomologist at Thailand-based Kasetsart University, welcomed the new development as “a major breakthrough in the battle against dengue and chikungunya viruses”. He told Scidev.Net that this is “a very simple combination but with a powerful effect on the ground leading to the killing of most vectors hidden in the containers”.

But Michael Turell, medical entomologist at USArmy Medical Research Institute of Infectious Diseases told SciDev.Net that educating people about how discarded trash provides breeding ground for disease-carrying mosquitoes could be as important as improving insecticides. “If these [trash cans] were turned upside down so that they would not hold water, I think it would have an even greater effect than a more efficient formulation of insecticides.”

NEW YORK, 19 May 2010 (IRIN) – The dangers of rapid and chaotic urbanization were made obvious in the aftermath of the 12 January earthquake in Haiti as the population of the densely populated capital city was left vulnerable to the disaster’s consequences.

But the superpower to the north has long overlooked the importance of urbanization in its deployment of foreign assistance, according to legislation now being considered by the Senate. The Sustainable Urban Development Act of 2010 – introduced by Sens. Benjamin Cardin (D-Maryland), Dick Durban (D-Illinois), and John Kerry (D-Massachusetts) on 20 April – directs USAID to better tackle the problems of enlarging slums, increasing levels of pollution, overburdened transport systems, and lack of affordable housing.

“We all recognize that the 21st century is the century of the city. There is an explosion of urban growth around the globe – already the majority of the world’s population lives in urban areas, with approximately one billion people residing in slums. The phenomenon of urbanization will be ignored at our own peril. Responsible citizens of the world must consciously harness their creativity and ingenuity to increase the livability, economic viability, and environmental sustainability of our cities,” said Kerry, introducing the bill.

“We all recognize that the 21st century is the century of the city. There is an explosion of urban growth around the globe – already the majority of the world’s population lives in urban areas, with approximately one billion people residing in slums. The phenomenon of urbanization will be ignored at our own peril. Responsible citizens of the world must consciously harness their creativity and ingenuity to increase the livability, economic viability, and environmental sustainability of our cities,” said Kerry, introducing the bill.

His point was reinforced at the recent World Economic Forum Africa meeting in Dar es Salaam, when Anna Tibaijuka, Executive Director of UN-HABITAT and UN Under-Secretary-General, emphasized that urbanization was one of the key challenges facing the continent. “Africa is urbanizing faster that any other continent, so much so that by 2030, Africa will cease to be a rural continent. Despite this, few African leaders are taking the issue seriously,” she said.

“It is time that policy makers include plans for balanced territorial urban development. This is one of the keys to economic growth especially as investment in infrastructure and housing in African cities provides a great opportunity for the private sector,” she said.

Reversing the trend

William Cobbett, programme manager of the Cities Alliance, told IRIN the bill was significant because it showed the US was prepared to formally recognize the importance of urbanization. He said that in the wake of a “very steady” decline of US aid in this area, he was heartened by the possibility that trend would be reversed.

“I just applaud its existence,” he said of the bill, which he has been sending to colleagues throughout the world as an example of forward-thinking public policy.

The legislation directs the administrator of USAID to update the Making Cities Work Urban Strategy, which has been in existence for almost a decade. It also suggests establishing a senior adviser for urban sustainable development at the agency and launching a “pilot urban strategies initiative” implemented in select cities in the developing world.

A spokeswoman for USAID said the agency would not comment on pending legislation and recommended reviewing the urban programmes in operation.

Scepticism

However, Alanna Shaikh, a global health professional who blogs at UNDispatch.com and other sites, wrote: “The ideas in the legislation are nothing new, and adding another mandatory annual report to an already overburdened agency is just annoying. Not to mention that the legislation doesn’t include any new financial resources; it calls for USAID to support all of this out of its existing budget.

“If Congress really wants USAID to scale up efforts to make urbanization beneficial, then they ought to allocate more money to make that happen. If you want a new focus and new programmes to support it, you need to find new money.”

A congressional aide speaking to IRIN on condition of anonymity countered that the bill was a “first step”. The objective was to “bring about some awareness that this is something that is a priority”. Nothing would assist that process more, he suggested, than a piece of legislation that has passed both houses of Congress and been signed into law by President Barack Obama. Congress would then “put the money where the policy is”, he said.

The legislation, the aide said, can be seen as part of the broader effort to rethink the US approach to development, exemplified by the ongoing Presidential Study Directive on Global Development – conducted by the White House’s National Security Council – and State Department’s Quadrennial Diplomacy and Development Review.

The bill must first be voted out of the Senate Foreign Relations Committee – of which all three Senators are members – before being considered by the full Senate.

OBJECTIVE: To describe urban-rural differences in breast cancer incidence in Gharbiah, Egypt and to investigate if these differences could be explained by known risk factors of breast cancer.

METHODS: We used data from the population-based cancer registry of Gharbiah, Egypt to assess breast cancer incidence from 1999 through 2006. The Egyptian census provided data on district-specific population, age, and urban-rural classification. Incidence patterns of breast cancer by district and age-specific urban-rural differences were analyzed.

RESULTS: Overall, incidence rate of breast cancer was three to four times higher in urban areas than in rural areas (60.9/10(5)-year for urban areas versus 17.8/10(5)-year for rural areas; IRR=3.73, 95% CI=3.30, 4.22). Urban areas had consistently higher incidence of breast cancer across all age-groups for all years. Higher incidence of breast cancer was also seen in the more developed districts of Tanta and El-Mehalla.

CONCLUSIONS: Higher incidence of breast cancer in urban and more developed populations might be related to higher exposure to xenoestrogens, as well as other endocrine disruptors and genotoxic substances.

The efficacy of insecticide-treated nets (ITNs) in prevention of malaria and anaemia has been shown in rural settings, but their impact in urban settings is unknown. We carried out an ITN intervention in two communities in urban Accra, Ghana, where local malaria transmission is known to occur.

There was evidence for a mass or community effect, despite ITN use by fewer than 35% of households. Children living within 300 m of a household with an ITN had higher haemoglobin concentrations (0.5g/dl higher, P=0.011) and less anaemia (odds ratio 2.21, 95% CI 1.08-4.52, P=0.031 at month 6), than children living more than 300 m away from a household with an ITN, although malaria parasitaemias were similar.

With urban populations growing rapidly across Africa, this study shows that ITNs will be an effective tool to assist African countries to achieve their Millennium Development Goals in urban settings. [Registered trial number ISRCTN42261314; http://www.controlled-trials.com/ISRCTN42261314].

Channels for change: private water and the urban poor

For the rapidly urbanising developing world, safe and affordable water is key to health and livelihoods, as well as meeting the Millennium Development Goals. But providing it demands innovative models. Where the context allows and the approach is appropriate, private sector involvement can generate win-win outcomes. Poor people can gain access to high-quality, affordable services, and companies can gain access to new and profitable business opportunities.

Two examples of innovative ‘private’ water suppliers are the Manila Water Company’s Water for the Poor Communities (TPSB) programme, and the Water & Sanitation for the Urban Poor (WSUP) partnership. Both have a multisector approach to service expansion and provision, including partnerships with local authorities; strong community involvement in selecting, designing and operating options; appropriate service levels to reduce costs;~and a flexible range of services. Many elements of these models are also replicable.

The government has been urged to review policies that hinder access to medical services and care of chronic conditions among poor urban dwellers.

According to research done by the African Population and Health Research Center (APHRC), 17% of people living in urban slums suffer from diabetes or hypertension and cannot get screening services or drugs partly due to government  policies that restrict delivery of these services to doctors operating from the district hospital level or above. As such, lower health facilities that are within reach of this population are not equipped with the necessary equipments for screening conditions such as diabetes and hypertension and even the medical staff are not trained on how to handle and care for such patients.

Rating of Cities under the National Urban Sanitation Policy announced yesterday is the part of the exercise started last year to create awareness about sanitation. The exercise of rating of Cities covers all major cities of the country and almost 72 percent of India’s total urban population. The country was divided into five zones for the purpose- North; South; West; East and North East and Central and South Central. Each city has been scored on 19 indicators which are divided into three categories: Output (50 points), Process (30 points) and Outcome (20 points).

The methodology for the exercise was designed incorporating standardized methods for measurement and scoring and was evolved after extensive stakeholder consultations. The rating makes use of both primary data collection during field visits and secondary data from published sources such as census. Each agency was required to follow the prescribed methodology, ensuring uniformity and comparability of data. The data was collected from cities in a consultative and collaborative manner. Based on the scores for output, process and outcome indicators, cities were then classified under four color categories; red, blck, blue and green.

The rating was carried out by three agencies i.e AC Nielsen-ORG Marg, Development and Research Services (DRS) and CEPT University, which were selected through a transparent and open bidding process. The process of data collection was carried out between December 2009 and March 2010 and was subsequently scrutinised in April by a team of experts. The results were communicated to State Governments as part of consultations and presented to the National Advisory Group on Urban Sanitation, the apex Group which oversees implementation of the Policy. The final consultations with States and Cities were held at Vigyan Bhawan before declaration of ratings.

The rating of Cities creates a baseline which can be used to measure progress in respect of sanitation in our cities and is expected to encourage cities to perform better in years to come. Based on the results of the rating, the best performers will be recognized with a National Award- “The Nirmal Shahar Puruskar”.

The award aims to recognize and reward improvements made by a city towards becoming totally clean and healthy by achieving 100% sanitation. A totally sanitized city is one that has achieved the objectives specified in the National Urban Sanitation Policy i.e open-defecation free city; universal access to toilets for all including the urban poor; elimination of manual scavenging; adequate provision of personnel protection equipment that addresses safety of sanitation workers; safe collection, treatment and disposal of all wastewater, solid waste and storm water; and recycle/reuse of treated wastewater with the ultimate objective of ensuring improved public health outcomes and environmental well being.

The exercise reveals that more than half of the cities are in the Blue or Black categories. There are four cities in the blue category which have scored above 66 but less than 90 marks out of hundred. Almost all cities report complete elimination of manual scavenging. More than 50 cities report 90 percent or above safe collection of human excreta. Twenty four cities collect more than 80 percent of their solid wastes – another six show an outstanding performance of nearly 100 percent primary collection. While treatment is a big challenge for most, 17 cities have achieved treating at least 60 percent of their wastes. Most cities have performed well in the process indicators, especially the larger cities, but results for the output and outcome indicators are mixed.

The exercise also highlights that considerable efforts are required to improve access to community and public toilets for the urban poor and to stop open-defecation. Wastewater treatment poses considerable challenges – 380 cities collect and treat less than 40% of their human excreta, though there are six cities that treat more than 90% of their human excreta.

It is expected that the ratings will help in bringing city sanitation in focus in all States and Cities. With significant enhancement in grants for urban local bodies under 13th Finance Commission recommendations, and assistance available under schemes like Jawaharlal Nehru National Urban Renewal Mission, Urban Infrastructure Scheme for Small and Medium Towns, Infrastructure Development Scheme for Satellite Towns, North Eastern Region Urban Development Programme, Backward Region Grant Fund, multilateral and bilateral funds and significant initiatives by States themselves, it should be indeed possible to move towards better levels of sanitation and the ratings seek to trigger this much needed change.

List of the rating of the cities on sanitation parameters ( 10 pages) is available on PIB site www.pib.nic.in.
