40 million Indians at risk from rising sea levels: UN report

The worst impacts of climate change are projected to occur in the Pacific and South and South-East Asia.



In 2011, six of the ten countries most vulnerable to climate change worldwide were in Asia and the Pacific.

Nearly 40 million Indians will be at risk from rising sea levels by 2050, with people in Mumbai and Kolkata having the maximum exposure to coastal flooding in future due to rapid urbanisation and economic growth, according to a UN environment report.
The ‘Global Environmental Outlook (GEO-6): Regional Assessments’ said the worst impacts of climate change are projected to occur in the Pacific and South and South-East Asia.
It said focussing on the population at risk from sea-level rise by 2050, seven of the 10 most vulnerable countries worldwide are in the Asia Pacific region.
India tops chart

India tops the chart with nearly 40 million people in the country projected to be at risk from rising sea levels, followed by more than 25 million in Bangladesh, over 20 million in China and nearly 15 million in the Philippines.
It said changes in settlement patterns, urbanisation and socio-economic status in Asia have influenced observed trends in vulnerability and exposure to climate extremes.
The report said in many coastal areas, growing urban settlements have also affected the ability of natural coastal systems to respond effectively to extreme climate events, rendering them more vulnerable.
“Some countries, such as China, India and Thailand, are projected to face increased future exposure to extremes, especially in highly urbanised areas, as a result of rapid urbanisation and economic growth,” it said.
It listed Mumbai and Kolkata in India, Guangzhou and Shanghai in China, Dhaka in Bangladesh, Yangon in Myanmar, Bangkok in Thailand, and Ho Chi Minh City and Hai Phong in Vietnam as projected to have the largest population exposure to coastal flooding in 2070.
“Many of these cities are already exposed to coastal flooding, but have limited capacity to adapt due to their fixed location,” it said.
The report, published ahead of the UN Environment Assembly taking place in Nairobi next week, said the worst impacts of climate change are projected to occur in the Pacific and South and Southeast Asia.
In 2011, six of the ten countries most vulnerable to climate change worldwide were in Asia and the Pacific.
The report said livelihoods can be impacted negatively by natural disasters, economic crises and climate change.
On coastal areas highly exposed to cyclones and typhoons, the poor tend to be more exposed to natural disasters because they live on land open to hazards.
Combined impact

Evidence suggests that climate change and climate variability and sea-level rise will exacerbate multi-dimensional poverty in most developing countries.
By 2050, areas of storm surge zones are expected for Bangladesh, China, India, Indonesia, and the Philippines, with a combined total of over 58 million people at risk.
The UN report further said global urban populations are projected to increase by 2.5 billion by 2050, with nearly 90 per cent of the increase in Asia and Africa.










     Action Plans fail to see through the smog
Earlier this month, the Delhi government was pulled up by the NGT for ignoring pollution from dust and garbage burning while mostly focussing on vehicular emissions, Independent studies have also stressed on a holistic efforts.
Delhiites have been breathing toxic air for years now. The annual concentration of the deadly PM2.5, which is particulate matter smaller than 2.5 microns in diameter, is more than twice the safe level. While the government does recognise the problem and action plans have been created, is it enough?
'Don't focus on one thing'
An analysis of the pollution control action plans shows that the Centre and the Delhi Government have focused their attention on vehicular pollution. Last week, the National Green Tribunal (NGT) raised a similar concern. “Why do not you [Delhi government] emphasise on the issues of dust and waste burning in a way you have emphasised on Odd-Even,” it asked.
The NGT was right. The much talked about Odd-Even scheme was aimed at halving the toxic emissions from cars, which are estimated to emit 2 per cent of Delhi’s air pollution, as per a source apportionment study by the Indian Institute of Technology-Kanpur.
Other culprits
But other sources which contribute a similar proportion – solid waste burning (3 per cent), hotel and restaurants (3 per cent), construction and demolition waste (2 per cent) and diesel generator sets (2 per cent) – have got far less attention or none at all.
“The kind of awareness that was created about pollution from transportation during the Odd-Even initiative should be created for all other sources. People don’t see industries and power plants every day, so it is easy to gloss over. But, they are a major source,” said Sunil Dahiya, a campaigner with Greenpeace.
“Instead of targeting smaller sources, the government should address industrial and thermal power plants across the National Capital Region. This will lead to a dip in pollution,” said Mr. Dahiya.
Priority concerns
But, vehicles do deserve the attention they are getting. Vehicular emissions, contributing to 20 per cent of particulate matter, are one of the most consistent sources of pollution throughout the year, as per the IIT-Kanpur report. The Odd-Even scheme happens to be just one of the many steps.
Vehicular emissions don’t just add to the overall pollutant concentration (ambient air quality), but lead to direct exposure that is even more crucial from a health perspective. And, according to a Union Health Ministry report in August 2015, “the highest immediate priority has to be accorded to sources that lead to the greatest levels of exposure and adverse health impacts”.
But, little has been done for two other sources that also lead to direct exposure – domestic cooking and solid waste burning.
Garbage burning, chulhas
Anumita Roychowdhury, the head of the Centre for Science and Environment’s clear air programme, said that though there was an NGT-ordered ban on burning of leaves and garbage, and a Rs.5,000 fine it wasn’t enough.
“The enforcement can’t be just symptomatic. There is a need for strengthening the waste management system. Civic bodies need to scale up efforts to compost, recycle, segregate and process waste,” she said.
Domestic cooking, which contributes to 12 per cent of particulate matter in the city, finds no place in the government’s action plan. Though the city has been declared ‘kerosene-free’, 10 per cent of households still burn wood, crop residue, cow dung, and coal for cooking.
“An energy transition plan should be in place. LPG connections were given to only those with legal status, leaving out residents of slums and unauthorised colonies,” said Ms. Roychowdhury.
As for MSW, a study by Nagpure et al found that 2 to 3 per cent of all garbage generated is burnt every day, mostly in winters for heating and in low-income areas that lack proper solid waste management. Though Delhi has started working on the solution, that is waste-to-energy plants, there have been hitches. Three WTE plants were planned, two are functional, and one, at Okhla, faced locals’ criticism for allegedly polluting.
The government’s plan seems to given concrete batching plants and hotels and restaurants, which together account for 9 per cent of pollutants, a miss.
Small steps
But, steps are being taken to rein in dust pollution, which is 38 per cent of the total. The Delhi government has started vacuum cleaning of roads owned by the Public Works Department. Also the government inspects construction projects and fines defaulters in order to control dust.
The pollution sources show that controlling emission is not a standalone problem, but interlinked with other urban issues. Access to clean energy for cooking, regular power supply, better solid waste management, and enhanced public transport will help reduce pollution, and improve quality of life.

UNEP releases landmark report at UN Environment Assembly
Environmental impacts are responsible for nearly 25 per cent of all deaths and there is an urgent need to place environmental issues at the centre of efforts to improve human health, according to a new study published by the United Nations Environment Programme (UNEP).
The danger posed by air pollution, chemicals, microplastics, zoonotic diseases and other environmental threats to human health have been revealed in a series of reports released at second United Nations Environment Assembly.
The reports show that environmental degradation and pollution is estimated to cause up to 234 times as many premature deaths as occur in conflicts annually.
The findings highlight the importance of a healthy environment to achieving the 2030 Agenda for Sustainable Development.
The report states that environmental impacts are responsible for the deaths of more than 25 per cent of all children under the age of five.
Healthy Environment, Healthy People - published by UNEP, the World Health Organization (WHO), the Convention on Biological Diversity, the Montreal Protocol on substances that deplete the ozone layer, and the Basel, Rotterdam and Stockholm conventions - assesses at the dangers posed by air pollution, chemicals, climate change and other issues linking environmental quality to human health and well-being.
UNEP Executive Director Achim Steiner said: "By depleting the ecological infrastructure of our planet and increasing our pollution footprint, we incur an ever-growing cost in terms of human health and well-being. From air pollution and chemical exposure to the mining of our natural resource base, we have compromised our life support systems.”
Mr Steiner (pictured) added: "A healthier planet is a rising tide that lifts all boats, including human health, but also economies and societies. By grounding development and progress in environmental health, we safeguard our own well-being. At UNEA-2, the world is focusing on pathways to ensure that the environment sustains human health rather than threatening it."
The report saysthat in 2012, an estimated 12.6 million deaths were caused by deteriorating environment conditions, or 23 per cent of the total.
The highest proportion of deaths attributed to environmental causes occurs in South-East Asia and in the Western Pacific (28 per cent and 27 per cent of the total respectively).
The number of deaths attributable to the environment is 23 per cent in sub-Saharan Africa, 22 per cent in the Eastern Mediterranean region, 11 per cent and 15 per cent in the Organisation for Economic Co-Operation and Development (OECD) and non-OECD countries of the Americas region, and 15 per cent in Europe.
The report outlines the drivers of the environmental health-related impacts - including ecosystem disruption, climate change, inequality, unplanned urbanization, unhealthy and wasteful lifestyles and unsustainable consumption and production patterns.
Climate change is exacerbating environment-related health risks and estimates from WHO indicate that 250,000 additional deaths could occur each year between 2030 and 2050, from malnutrition, malaria, diarrhoea and heat stress, as a result of climate change.
The report suggest that air pollution kills 7 million people across the world annually, with 4.3 million of those deaths caused by  household air pollution.
A lack of access to clean water and sanitation results in 842,000 deatsh from diarrhoeal diseases every year, 97 per cent occurring in developing countries.
The study shows that exposure to chemicals is another killer with about 107,000 people dying annually from exposure to asbestos, and 654,000 died from exposure to lead in 2010.
The report says that since 1995, 606,000 deaths have been caused by natural disasters and 4.1 billion people have been injured, left homeless or in need of emergency assistance as a result of weather-related disasters.
According to the new resear4ch, the successful phase-out of nearly 100 ozone-depleting substances (ODS) means that up to 2 million cases of skin cancer and many millions of eye cataracts may be prevented each year by 2030.
Benefits from eliminating lead in gasoline worldwide have been estimated at $2.45 trillion per year, saving an estimated 1 million premature deaths per year.
Implementing effective measures to curb emissions of short-lived climate pollutants including black carbon and methane could reduce global warming by 0.5°C by the middle of the century, and save 2.4 million lives a year from reduced air pollution by 2030.

UN Environment Assembly Kicks Off In Nairobi to Drive Environmental Progress on Sustainable Development
Mon, May 23, 2016

Parliament for the Environment Gets Underway as High Level Officials Gather to Combat Some of the Most Pressing Problems of the Day .

Nairobi, 23 May 2016 - Hundreds of key decision-makers from all over the world meet in Kenya today for start of the second United Nations Environment Assembly (UNEA-2), where they will tackle some of the most critical issues of our time, from the air pollution that kills millions of people every year to an illegal trade in wildlife that is pushing species to the brink of extinction.
Held at the headquarters of the United Nations Environment Programme (UNEP) in Nairobi, UNEA is the world's most powerful decision-making body on the environment. This year, leaders will seek to pass a raft of resolutions that address a number of the world's most pressing challenges, including food waste, the fading health of our oceans, the world's natural capital, and sustainable consumption and production.
A series of ground-breaking UNEP reports that shine a light on the state of the world's environment will also be released during the assembly, offering solutions that will help the world overcome these challenges.
UN Under-Secretary-General and UNEP Executive Director Achim Steiner said: "The world must seize this opportunity - the first global decision-making platform since the 2030 Agenda and Paris Agreement - to review and accelerate progress towards a greener, better future for all.
"UNEA provides the world with a chance to unite in a common struggle against the forces of hunger, poverty, climate change and environmental damage. We must use UNEA-2 to show we can move fast enough and hard enough to create a healthy planet, with healthy people, which leaves no one behind."
More than one thousand delegates from across the world - from governments, businesses and civil society - will attend UNEA-2. Among those attending the assembly are Kenyan President Uhuru Kenyatta, Iran's vice president, Ireland's Former President Mary Robinson, the director-general of the World Wildlife Fund, the political director of Greenpeace, the CEO of Kiira Motors and government ministers from across the globe, including French Ecology Minister Ségolène Royal.
All 193 UN member states, along with major stakeholders, are represented at UNEA-2, which convenes from 23-27 May 2016. With this wide reach into the legislative, financial and development arenas, the body presents a ground-breaking platform for leadership on global environmental policy.
For many, the creation of UNEA represents the coming of age of the environment. Since UNEP's inception in 1972, the environment has moved from the margins to the centre of the world's sustainable development agenda.
This transition was affirmed at the historic United Nations Conference on Sustainable Development (Rio+20) in June 2012, when world leaders called for UNEP to be strengthened and upgraded. The result was a new governing body, UNEA, which - for the first time - gives the environment the same level of global prominence as issues such as peace, poverty, health, security, finance and trade.
About UNEA
The United Nations Environment Assembly (UNEA) is the world's most powerful decision-making body on the environment, and responsible for tackling some of the most critical issues of our time. The assembly holds the power to dramatically change the fate of the planet and improve the lives of everyone, impacting everything from health to national security, from the plastic in our oceans to the trafficking of wildlife. Thanks to UNEA, the environment is now considered one of the world's most pressing concerns alongside other major global issues such as peace, security, finance and health.
This year, hundreds of key decision makers, businesses and representatives of intergovernmental organizations and civil society will in May gather at UNEA-2, taking place at the United Nations Environment Programme headquarters in Nairobi, for one of the first major meetings since the adoption of the 2030 Agenda for Sustainable Development and the Paris Climate Agreement. The resolutions passed at UNEA-2 will set the stage for early action on implementation of the 2030 Agenda, and drive the world towards a better future, more-just future. UNEA-2 is also inclusive, with myunea.org allowing citizens to feed their concerns into the meeting and take personal ownership of the collective challenges we face.

As the planet scorches

Study suggests that using up all fossil fuels would make the Earth even more unliveable
Using up all known fossil fuel reserves would render Earth even more unliveable than scientists had previously projected, researchers said on Monday.
Average temperatures would climb by up to 9.5 degrees Celsius — five times the cap on global warming set at climate talks in Paris in December, they reported.
In the Arctic region — already heating at more than double the global average — the thermometer would rise an unimaginable 15 C to 20 C. Most of the UN climate science panel's projections for greenhouse gas emissions do not forecast beyond two trillion tonnes of carbon, more than enough to unleash a crippling maelstrom of rising seas, drought, heat waves and floods.
Indeed, to have a better-than-even chance of holding global warming at 2 C, the total carbon budget is about one trillion tonnes, the UN has said.
But extreme modelling scenarios cannot and should not be ignored, said lead author of the study.
There was still no guarantee that the 195 nations which forged the Paris Agreement will deliver on their collective pledge to hold global warming to under 2 C (3.6 F) by cutting back on fossil fuels.
Negotiators reconvened in Bonn this week to start turning the landmark political deal into an operational plan, but have found themselves bogged down in procedural discussions.
"Policymakers need to have a clear view of what is at stake... if no meaningful climate policies are put in place," said Thomas Frolicher, an expert on environmental physics at the science and technology university ETH Zurich, said.
Previous research had projected that Earth's temperature rise would slow down once the level of two trillion tonnes is reached — beyond that threshold, the impact of additional carbon diminishes.
Using up-to-date climate models, however, Tokarska and colleagues showed that much of this work had over-estimated the oceans' capacity to absorb the CO2 humans pumped into the air, along with the additional heat it generates.
"The ocean takes up heat more slowly under those conditions," offsetting the slowdown in temperature rise, she explained by email.
Older models had projected that depleting fossil fuel reserves entirely would heat the planet by 4.3 C to 8.4 C. The new study revises this to between 6.4 C and 9.5 C.
Even if humanity manages to drastically curb its use of oil, gas and coal, Nature could add massive amounts of greenhouse gases all by itself, scientists warn.
Hundreds of billions of tonnes of carbon, mostly in the form of methane, are locked in the increasingly misnamed permafrost of the sub-Arctic region. Beyond a certain threshold — and no one knows what that is — global warming could irretrievably unlock these methane reserves.AFP
Peru declares mining-related emergency in remote part of Amazon
The Hindu tiled “Mercury pollution leads to emergency” (25 May 2016)
LIMA May 23 (Reuters) - Peruvian President Ollanta Humala has declared a 60-day emergency in a remote part of the Amazon to curb high levels of mercury poisoning from rampant illegal gold mining, the country's environment minister said on Monday.
A growing number of studies show that residents of the Madre de Dios region near Peru's southeastern border with Brazil have dangerous levels of mercury in their bodies, Environment Minister Manuel Pulgar-Vidal said in announcing the move.
Tens of thousands of illegal miners who dredge for gold in the rivers and wetlands of Madre de Dios use mercury to separate ore from rock, often handling the neurotoxin with their bare hands and inhaling its fumes when it is burned off.
The miners dump about 40 tonnes of mercury into Amazonian rivers per year and have destroyed more than 100,000 hectares (247,105 acres) of rainforest in Madre de Dios, according to the environment ministry.
"Forty-one percent of the population of Madre de Dios is exposed to mercury pollution," Pulgar-Vidal said in a news conference.
Indigenous and rural communities are particularly vulnerable because they rely heavily on river fish for protein, the minister added.
As part of its emergency declaration, the government plans to provide uncontaminated fish to residents in Madre de Dios. It also intends to set up mobile health clinics and monitoring centers and implement educational campaigns, Pulgar-Vidal said.
Humala, who will leave office when his five-year term ends on July 28, launched a crackdown on wildcat gold mining in Madre de Dios in 2012, but miners have continued to expand into nature and indigenous reserves. (Reporting by Mitra Taj; Editing by Paul Simao)
Pollution
Thermal power plants leading to spike in SO2, NO2: study
The govt. notified norms for sulphur dioxide and nitrogen dioxide emissions in December 2015, but these have not been implemented, says expert
Clusters of thermal power plants in Northern India were the sources of growth in emissions of highly toxic and reactive gases in the past few years, a report released here on Monday found.
The report titled “Out of Sight: How coal burning advances India’s air pollution crisis” by Greenpeace India used satellite imagery from 2009 to 2015 to find that areas that had thermal power plants in Madhya Pradesh’s Singrauli, Chhattisgarh’s Korba and Raigarh, Odisha’s Angul, Maharashtra’s Chandrapur, Gujarat’s Mundra and the National Capital Region were behind the growth in emissions of sulphur dioxide and nitrogen dioxide.
Rise in emissions
As per the report, emissions of the toxic sulphur dioxide gas increased by 31 per cent from 2009 to 2015.
The emissions of nitrogen dioxide, which is highly reactive, increased by 20 per cent during the same period.
Both these gases react in the air to form secondary particles, which account for a major chunk of Delhi’s pollution.
The Greenpeace report showed that the concentration of fine particulate matter (PM2.5) rose by 13 per cent in the past five years.
Sunil Dahiya, one of the authors of the report and a campaigner with Greenpeace, said that many studies had earlier found that 30 to 34 per cent of the total PM2.5 concentration in the country was due to secondary particles.
“Most of these secondary particles are formed from burning of fossil fuels, like in thermal power plant. It is no coincidence that the hot spots of sulphur dioxide and nitrogen dioxide overlap with the areas with highest coal consumption,” said Mr. Dahiya.
In Delhi, Mr. Dahiya said that though the power generation was limited, emission from thermal plants in the National Capital Region was affecting air quality in the city.
‘Clear link’
In fact, a recent report by IIT-Kanpur had said that a plan to reduce pollution in Delhi must include a radius of 300 kilometres around the Capital.
“We have established a clear link between thermal power plants and rise in pollution in the region. There is an urgent need to get emissions from these plants under control,” said Mr. Dahiya.
Emission norms
The government had notified norms for sulphur dioxide and nitrogen dioxide emissions in December 2015, but these have not been implemented till now, said Mr. Dahiya.
He added that these norms should be in place within two years from the notification to have an impact on air quality.
As per the report, emi 31 per cent from 2009 to 2015

Adilabad artisans await online marketing support
Traditional brass artefacts made by tribal Ojha craftsmen of Adilabad district.Photo: S. Harpal Singh
Craftsmen say buyers find location a handicap but they can't leave traditional markets.
The absence of Adilabad’s traditional handicrafts in lucrative urban markets is an aberration to the reputation enjoyed by the Dhokra metal artefacts and softwood Nirmal Toys made by the poor Ojha and Naqash craftsmen.
The one way of bridging the gap between the traditional craft and urban markets is to sell the products online, which will also substantially increase the artisans’ income.
Earlier initiatives failed
Not that there has been no effort towards such an enterprise. But a couple of initiatives made last year to sell Nirmal toys online came a cropper. Also, the Telangana government’s announcement of facilitating online marketing of the softwood toys is yet to materialise.
A non-governmental organisation developed a website for the online sale of the toys but it could not become operative as the Naqash craftsmen found packaging the products difficult. The Department of Posts too came forward to sell the toys through its network, but for some reason it did not see the light of day either.
“Purchasing cartons for packing the toys was expensive,” said Nirmal Toys and Arts Industrial Cooperative Society Manager B.R. Shankar.
Metal casting
For the Ojha craftsmen of Jainoor, Kerameri and Tamsi mandals, who have traditionally been making artefacts used by the Gond Adivasis in agriculture and religious activities, there has been no such effort. The community has, however, been benefiting from several workshops aimed at design development in their brass metal casting craft.
“We will certainly benefit from any support towards online marketing of our products as buyers find it tough to reach our remote villages. Our location is a handicap but we cannot leave our traditional markets,” said Uike Indrajeet, Ojha craftsman from Belsari Rampur in Tamsi mandal.
The Ojhas will not find it difficult to handle online marketing as it has a few youths educated sufficiently to package and ship the products. The website, however, needs to be developed by experts.

Potassium bromate in same cancer class as coffee
Source: http://www.thehindu.com/sci-tech/health/carcinogen-in-bread-potassium-bromate-in-same-cancer-class-as-coffee/article8642121.ece

Less toxic than processed and red meat.
Potassium bromate, the chemical additive widely prevalent in bread and refined flour and associated with cancer, is in the same league as coffee, aloe vera, mobile phone radiation and carbon black, a key ingredient in eye-liner.
It also is less toxic than processed and red meat, according to a perusal by The Hindu of the list of agents deemed potentially cancerous by the International Agency For Research on Cancer (IARC) — a World Health Organisation body.
The intergovernmental agency’s periodic reviews play a critical role in determining national decisions to ban or regulate the use of certain substances and often make news when it pronounces judgment on the carcinogenic potential of agents such as coffee and the use of wifi.
Ubiquitous in bread
Potassium bromate, according to an investigation made public on Monday by the Centre for Science and Environment, was ubiquitous in several brands of bread and refined flour products including burgers and pizza, in Delhi.
The CSE referenced the IARC’s classification of potassium bromate to bolster its claim.
In its nearly four decades of existence, the IARC has evaluated 989 agents for their association with cancer.
Based on the quantity and quality of scientific evidence that is available through peer-reviewed literature and documented reports on the risk of cancer, the IARC follows a five-step grading scheme, the highest of which is Grade 1, or substances that are proven to cause cancer in humans, and the lowest at Grade 4 where there is definite proof that there is no link to cancer.
There are grades 2A and 2B which include potassium bromate and coffee — that differentiates between agents ‘probably’ and ‘possibly’ associated with cancer. These grades makes up the bulk — 791 — of the agents that have so far been tested by the IARC.
There are 118 agents classed in Grade 1 and only one, caprolactam, listed as ‘probably not cancerous.’
‘No risk assessment’
An IARC spokesperson told The Hindu that it differentiated between ‘risk’ and ‘hazard,’ where a hazard reflected how often a substance had been linked to cancer in humans and animals, and ‘risk’ indicating the probability of someone contracting cancer by exposure.
“IARC doesn’t do risk assessment,” Veronique Terrasse, spokesperson IARC, said.
“The types of exposures, the extent of risk, the people who may be at risk, and the cancer types linked with the agent can be very different across agents. Therefore, comparisons within a category can be misleading.”
She added that the IARC would be revisiting in June reports of links between cancer and coffee.
Active smoking, according to the IARC’s primer on interpreting cancer categories, carried a much higher risk of lung cancer than air pollution, although both are categorised in Group 1.
Another food safety expert said that while India by-and-large followed international regulations to decide whether to ban agents, there were instances of products allowed in India and disallowed abroad.
“Aloe vera is allowed as per our regulations [for skin products]) but internationally there have been [cancer] concerns over it,” said S.M. Bhardwaj, a senior official in the Delhi government’s food safety department.

Largest gene database of Indians soon

The project will develop in phases and the entire record will be ready by 2020
In a move to create one of the largest repositories of Indian genomes, Bangalore-based Medgenome has teamed up with a Southeast Asian consortium that has committed to sequence 100,000 Asian genomes. Were it to work to plan, this could mean a consolidated storehouse of at least 30,000 Indian genomes and could help understand the wide genetic variety in India’s various ethnic groups and midwife customised medications for cancer and heart disease, as well as identify possible new genetic aberrations that cause untreatable diseases.
Collection of samples
Ever since the human genome was first sequenced in 2003, that is the entire DNA pattern in the cell that lends people their unique identity was deciphered, several countries have announced initiatives to map genomes of their resident populations. The so-called 1000 Genomes project is a collection of gene samples from across the world to capture the variety of genes that are typical to different population groups. The United Kingdom announced a plan in 2014 to create a bank of 100,000 genomes in the nation and 100,000 Asia genomes project — called GenomeAsia 100K — echoes similar ambitions. “Indian populations are greatly neglected in such databases,” said Mahesh Pratapneni, Executive Director, Medgenome, and a top official with the GenomeAsia 100K. “It is glaring considering we’re one-sixth of humanity.”
The project will develop in phases with an initial 1000 genomes, consisting of India and East Asian populations, sequenced within this year, and the entire database to be ready by 2020. Medgenome already has a bank of 200 Indian genomes.
$120 million project
The project will cost $120 million (approx. Rs 800 crore), though only about half of that has been firmed up. Other key collaborators in the project are Singapore’s Nanyang Technological Institute, Singapore, and Macrogen, a genetics diagnostic company in Seoul. Nearly 60 petabytes of data — equivalent to 30 trillion pages of text — are expected to be churned out in this study. Though all this data would be publicly available to researchers, access to it would be staggered. “We will release it all over 3-4 years but the main contributors to the project would access this earlier,” Mr. Pratapneni told The Hindu .
Though human genome sequencing is a frontier area of biotechnology, it was prohibitively expensive. Technology advancement has made prices dramatically drop, enabling several companies to offer genome sequencing services. Experts however say that while the cost of sequencing has fallen, it is the analysis of genes that adds value, and that would mean being able to access and compare huge datasets.
While many diseases are linked to genes going awry, afflictions such as diabetes, cardiovascular diseases, cancer, etc., are usually the result of several genes malfunctioning, and often in a domino-like effect. Identifying such culprits is impossible without comparing genes, across individuals and population groups, in large numbers. Thus BRCA 1 and BRCA 2 — genes associated with breast cancer — are found in as many as one-third of women. Several of them go on to live without ever contracting the cancer. These genes come in several varieties that can vary on the level of families as well as ethnicities. Genome sequence studies are effective in studying such variations.
‘Good initiative’
“It’s a good initiative and could throw up valuable data provided there is a good study design in place,” said Samir Brahmachari, former head of the Council of Scientific and Industrial Research, who led the country’s first initiative to sequence an Indian genome.
