I just took part in a public screening of HOME, the 2009 documentary that offers a new view of our planet — from slightly above.
French photographer, journalist and activist Yann Arthus-Bertrand and his team travelled around the planet over 18 months to make this film. They filmed interesting natural and human-made locations in 50 countries — all from the air. This offers a different perspective to our growing impact on the planet’s natural processes and balances.
Technically outstanding and aesthetically enjoyable as it is, does HOME overstate the case for planet-saving action? Or does it gloss over deep-rooted causes of today’s ecological crisis? These and other questions were raised and discussed at our screening.
HOME the movie screening in Colombo, 13 March 2014
I was encouraged by over 60 people turning up – a mix of students, professionals, retirees and others – and staying transfixed for the two full hours – plus another 45 mins of Q&A. This is just a summary of wide ranging discussion moderated by filmmaker and film buff Sudath Mahadivulwewa.
We discussed both style and substance. I personally dislike the patronising narration by actress Glenn Close – who reminds me of an all-knowing old matron. But a few felt that this theme demanded just such a voice and delivery.
We agreed that HOME isn’t a typical natural history or environmental documentary. Its scope is vast (story of our planet and human civilisation), its vantage viewpoint extraordinary.
With all its stunning views and haunting music, HOME projects a strong message of anthropocentrism – that human beings are the central or most significant species on the planet (at least in terms of impact). This is now a dominant view among scientists who study the planet (hence the new name for our times, Anthropocene).
I sometimes wonder – as did some in my audience – whether we take too much credit for our signature on the planet. We sure are the most damaging species, but I worry about environmentalism turning into a religion-like dogma. I have always stayed clear of ‘Mother Earth’ kind of romanticising – we don’t need to turn the planet into a gigantic matriarchy to be motivated to care for it!
Besides, some geological processes — such as volcanic eruptions, earthquakes and tsunamis — are not triggered by human action. When I hear die-hard greens trying to link these phenomena to humanity (never mind the absence of any evidence), I consider it environmental advocacy going crazy.
I also drew my audience’s attention to Alan Weisman’s 2007 best-seller The World Without Us, which offers an original approach to questions of humanity’s impact on the planet: he envisions our Earth, but without us. We may be a formidable presence right now, but if we disappear, the planet would slowly but surely reassert itself…
Is HOME political enough? Some argued the film left too much for individual thought and action when, in fact, much of today’s resource crises and environmental problems stem from structural anomalies and deeply political disparities in the world. Is this an attempt to absolve the governments and corporations of responsibility and heap it all on individuals?
Opinion was divided, but it got us talking – and thinking. I don’t know Yann Arthus-Bertrand, but perhaps he kept the message at personal level so his film can be non-threatening and benignly subversive? There are times when harsh delivery can alienate part of the intended audience.
All considered, an evening well spent. As I’d tweeted in advance, we had a slightly out of this world experience with Arthur-Bertrand as our guide – and no reality altering substances. Indeed, the stark reality facing humanity can be very sobering…
In this week’s Ravaya column (in Sinhala), I summarise concerns about the draft new Seed Act of Sri Lanka proposed by the government’s Department of Agriculture. Many farmer groups and environmental activists have serious misgivings about proposals to centralise all seed sharing and trading in the head of the Department of Agriculture. Activists see this seriously undermining those using and protecting traditional varieties of seed and engaged in organic farming.

“To garner public support for their causes, the development community must connect with rest of society using everyday phrases, metaphors and images. That is a far better strategy than expecting everyone to understand their gobbledygook.”
This is the central argument in my latest op-ed essay, just published on the Communication Initiative blog.
Titled Crossing the ‘Dev-Code’ Divide, I revisit a theme familiar to my regular readers: getting development pr0fessionals to communicate better.
Another excerpt:
“After working with technological ‘geeks’ and development workers for many years, I know they have at least one thing in common: their own peculiar languages that don’t make much sense to the rest of us.
“Talking in code is fine for peer-to-peer conversations. But it’s a nonstarter for engaging policy makers and the public.”
This essay is a tribute to my mentor and former colleague Robert Lamb (1952 – 2012), who was a grandmaster in communicating development to public and policy audiences using simple language and powerful imagery.
Working with Robert for 15 years, I saw how he brought seemingly dreary development issues alive on TV and video – dominant media of his time — through simple and sincere story telling. He mixed inter-governmental processes with stark ground level realities. In three decades he produced or commissioned hundreds of international TV documentaries exploring what sustainable development meant in the real world.
In this week’s Ravaya column (in Sinhala), I continue my exploration of the global Slow Movement, which started with Slow Food in Italy in 1986, originally as a defiance of fastfood. It has since inspired other pursuits of doing things more reflectively and deliberately slowly – such as Slow Cities, Slow Reading, Slow Travel and Slow Art.
In this week’s Ravaya column (in Sinhala), I discuss the merits of Slow Food, a concept that originated from Italy in 1986 in defiance of fastfood — but has since grown into a worldwide social movement that critiques industrialised food production and consumption. It has also inspired other pursuits of doing things more reflectively and deliberately slowly – such as Slow Cities, Slow Reading, Slow Travel and Slow Art.
Go organic! That call is heard increasingly in Sri Lanka, which has been late to get on this bandwagon. Much of the island nation’s organically produced fruit, spices and vegetables was exported to high-paying overseas markets until recently. But concerned with health effects of agrochemical residues in the good, more Lankans are now looking for organic products.
Is this an upper middle class fad, or can organic food become the mainstream? What about the significant price difference? What assurance of quality and where are the certification schemes?
In my latest Ravaya column (in Sinhala), I survey the small but rapidly growing organic produce market in Sri Lanka, and raise some questions that need regulatory and consumer attention.

South Asia Coastal Management Convention in Pondicherry – L to R Chandra Bhushan, Aurofilio Schiavina, Sunita Narain, Tahir Qureshi, Anil Premaratne
South Asian Coasts Reeling Under Pressure
By Nalaka Gunawardene in Pondicherry, India
As economic development gathers pace in South Asia, its coastal regions are coming under pressure as never before. More ports, power plants and tourist resorts are jostling with fishermen and farmers.
Balancing livelihoods, economic growth and environmental conservation is the only way to avoid a major resource crisis, acknowledged participants at the South Asia Convention on Coastal Management held in Pondicherry, India, from 19 to 21 January 2014.
Over 70 senior government officials, researchers, civil society activists and journalists from Bangladesh, India, Maldives, Pakistan and Sri Lanka came together for this event, organised by Delhi-based Centre for Science and Environment (CSE) and Pondicherry-based citizen group, PondyCAN.
They reported how a disproportionately high share of South Asia’s industrialisation, urbanisation and tourism development is concentrated along its combined 11,240 km of coastline. In total, coastal areas support livelihoods of some 400 million South Asians through fisheries, tourism and other activities.
In many parts of the region, high population density exists alongside sensitive ecosystems – such as mangroves and coral reefs and river estuaries. This intensifies the challenge of managing coastal resources. Climate change impacts, already felt as extreme weather events, add to these pressures.
Participants discussed strategies for regulating coastal development, protecting coastal habitats and coping with climate change.
They agreed on the urgent need for improving scientific understanding of coastal regions, which begins with clearly defining, demarcating and mapping such areas. Evidence based policy making and effective regulation depend on such a knowledge base, currently lacking or inadequate.
“There is a need to strengthen regulatory systems, build capacity and do more research to better manage coastal challenges in South Asia,” said Sunita Narain, Director General of CSE.
In CSE’s view, she said, the most important intervention is to strengthen existing institutions to get them to deliver with greater transparency and accountability.
She added: “We need to balance conservation with benefits to local communities. We also need partnerships between conservation, development and livelihoods without which coastal resource management is not possible in a region like South Asia”.
Only such an approach can reconcile the many pressures faced by South Asia’s maritime countries including poverty, depleting resources, increasing hazards and large scale enterprises seeking quick profits from the coastal resources.
“We need to make sure these plans incorporate climate change to make them more meaningful to countries like ours,” he added.
Large scale infrastructure development projects are adding to other pressures. India – which already has 202 commercial ports and 27 thermal power plants on its coastline – is planning another 76 ports and 59 power plants. Over 70% of Sri Lanka’s tourist hotels are located in the coastal zone, with more coming up. The scramble for the coast is increasing in other countries, too.
Meanwhile, over two thirds of the world’s ship breaking takes place on open beaches in Bangladesh, India and Pakistan with little regard for worker health or environmental pollution. It is a highly hazardous industry with lucrative returns for operators.
Participants agreed on the need for the South Asian countries to share experiences and approaches and to learn from each other.
Premaratne pointed out that laws and regulations are just one strategy for better managing coastal areas. Other strategies include awareness raising and public education, and the involvement of local communities in resource management and benefit sharing.
Participants also stressed the need for placing all scientific information and maps in the public domain. Right now, these are often trapped in state agencies or research institutes, with no easy access to researchers or other citizens.
Probir Banerjee, President PondyCAN, stressed that the “worst affected are the people living at the margins and the objective has to be to enhance livelihoods, and not compromise them.”
In this week’s Ravaya column, I feature Indian agricultural scientist and activist Dr Anupam Paul, who is committed to organic farming and preserving traditional varieties of rice (folk rice).
He was in Colombo in December 2013 when I had an interesting interview on the uphill struggle to sustain in-situ conservation efforts working with a handful of committed farmers who still grow folk rice varieties instead of hybrid ones promoted by the Green Revolution.
While unexplained mass kidney failure is a serious public health problem in Sri Lanka, some persons are exaggerating the number of cases and deaths resulting from it, says the kidney specialist who first detected the disease.
Consultant Nephrologist Dr Tilak Abeysekera, who heads the Department of Nephrology and Transplantation at the Teaching Hospital Kandy, told a recent scientific meeting that it is very important to correctly diagnose the ailment – and not get it mixed up with other types of kidney disease.
“For example, only 16% of kidney patients in the Anuradhapura district can be classified as affected by what is now called Chronic Kidney Disease of unknown aetiology, or CKDu,” he said. He was speaking at a national symposium organised by the National Academy of Sciences of Sri Lanka (NASSL).
The symposium, held in Colombo on 10 December 2013, brought together senior representatives from many public institutions, research organisations and advocacy groups. It discussed the current status of knowledge of the disease, its occurrence, cause(s) and the short and long-term action needed to combat or mitigate it.
Wide-ranging discussions at the symposium highlighted the need for better disease surveillance, and further research. Participants also agreed on the need for much caution by policy makers and the media to avoid creating panic and confusion.
“Some writers to newspapers have claimed that the kidney disease is worse than the (2004) tsunami. The two tragedies are not comparable, and many numbers being mentioned in the media are gross exaggerations,” Dr Abeysekera said.
Mystery disease
CKDu emerged in the early 1990s, when hundreds of people in Sri Lanka’s Dry Zone – heartland of its farming — developed kidney failure without having the common causative factors of diabetes or high blood pressure.
Most affected were men aged between 30 and 60 years who worked as farmers. The disease built up inside the body without tell-tale signs or symptoms, manifesting only in advanced stages.
Dr Abeysekera was the first to notice and report this variation of the disease that had no immediately apparent cause. As the numbers rose, doctors and other scientists began probing further, trying to identify factors that triggered kidney failure.
Having first appeared in the North Central Province, CKDu has since been reported from parts of five more provinces: the North Western, Uva, Eastern, Central and Northern. The endemic area now covers around 17,000 square km, which is home to over 2.5 million people. To date, it remains exclusively a Dry Zone disease.
Owing to discrepancies in record keeping, it is difficult to arrive at a reliable estimate of deaths resulting from CKDu, According to Dr. Kingsley de Alwis, President of NASSL, deaths have variously been estimated at between 20,000 and 22,000 over the past 20 years. These numbers are not fully verified.
According to him, some 8,000 persons are currently undergoing treatment. This costs the public health sector over Rs. 4,000 million every year.
Over the years, many scientific studies have been carried out and various environmental, geochemical and lifestyle related factors have been probed. Researchers now suspect environmental and genetic factors as causes – but a definitive link to a specific factor has yet to be found.
The National CKDu research project, initiated and led by the Ministry of Health during 2009-2011, has concluded that CKDu is caused by multiple factors instead of a single one (see also box below).
In particular, it found chronic exposure of people in the endemic area to low levels of Cadmium through the food chain and also to pesticides. It also reported a genetic susceptibility in individuals with CKDu.
Many causes
Dr Shanthi Mendis, Director, Management of Non-communicable Diseases at WHO, told the symposium that kidney disease due to environmental factors is not unique to Sri Lanka. It has also been reported from Japan, Nicaragua, El Salvador, Croatia, Bulgaria and Serbia among others.
In Sri Lanka, WHO-supported research has shown that men over 39 years of age who are engaged in chena cultivation are more prone to CKDu. A positive family history in parents or siblings also increases the risk.
According to Dr Mendis, among the factors that appear to play a role are: chronic exposure to low levels of Cadmium through the food chain; exposure to nephrotoxic (kidney-damaging) pesticides; concurrent exposure to other heavy metals (Arsenic and Lead); deficiency of Selenium in diet; genetic susceptibility to kidney failure; and the use of Ayurvedic herbal remedies containing the Sapsanda plant (Aristolochia indica).
Cadmium enters the environment mainly through chemical fertilisers. The national research project did not find drinking water as a main source of Cadmium.
“In endemic areas, high Cadmium levels were found in certain vegetables such as lotus roots, freshwater fish and tobacco. But Cadmium in rice in both endemic and nonendemic areas was less than the allowable limit of 0.2 milligrams per kilogram,” Dr Mendis said.
Traces of Fluoride and Calcium naturally occurring in groundwater may also aggravate the effect of nephrotoxins and contribute to CKDu, she added.
Agrochemicals are not the only substances to watch. Dr Mendis also highlighted 66 Ayurvedic medicinal prescriptions that contain Aristolochia, being used for treating over 20 ailments. These include remedies for snakebite, fever, body pains, labour pain, indigestion and headache. Most people have no idea what their medicine contains, making it particularly difficult to assess exposure to this factor.
As often happens, research has raised more questions while clarifying some issues. Further studies are needed to understand exactly how certain plants accumulate heavy metals from their surroundings.
According to NASSL President Dr de Alwis, this is the typical process of science. “We need not be unduly alarmed about the number of different causes to which CKDu is attributed by scientists…Science works through a series of interactions, as well as the clash of ideas.”
Dr Tissa Vitarana, Senior Minister of Scientific Affairs who opened the symposium, asked all researchers to keep an open mind in such scientific investigations, ensure rigour of testing and analyis, and discuss their findings widely.
“There has been a spate of media abuse on CKDu. I’m glad to note that the media hype has died down so that a more sensible evaluation becomes possible,” he said.
Dr Vitarana, who is a virologist by training, added: “Cadmium, the main heavy metal suspected of being responsible for CKDu, enters our environment mainly through chemical fertilisers. There is no argument that we need to reduce use of such fertilisers. But as a scientist, I need to be convinced that Cadmium is the main cause. Right now, there is no such conclusive evidence, so we need to keep an open mind.”
Remedies & prevention
While the debate on exact causes of CKDu continues in scientific circles, the public health toll keeps rising.
“CKDu is a major public health issue placing a heavy burden on Government health expenditure and is a cause of catastrophic expenditure for individuals and families leading to poverty and stigma in the community,” WHO’s Dr Mendis said.
And as Minister Vitarana noted, in affected areas of the Dry Zone, farmers’ morale is breaking down. “This can raise questions on the future of farming in Sri Lanka.”
Based on the National CKDu research project, WHO has recommended a number of short and long term actions for ministries and other state agencies concerned with health, water supply, food and agriculture sectors.
An urgent priority is to supply clean drinking water to all people living in the endemic districts. Most people currently rely on groundwater, tapped through tube wells, hand pumps, or dug wells. The government’s 2014 budget proposals have recently allocated Rs 900 million to set up Reverse Osmosis small treatment plants that can purify ground water at local level.
Meanwhile, acting on other recommendations, the Ministry of Health has intensified public education and CKDu surveillance. At the same time, more treatment facilities – including kidney dialysis units – are being set up.
Many families of patients living with CKDu face economic hardship as their breadwinner can no longer work. They need both livelihood and counselling support.
On the preventive front, the Health Ministry now advises against consuming lotus roots in endemic areas, and asks people to be careful with all herbal medicines containing Sapsanda. One study recommendation is for regulating the use of nephrotoxic herbal medicines.
The national research study has also recommended action for stricter regulation of agrochemicals. It specifically calls for regulating the indiscriminate use of synthetic fertilisers, in particular phosphate fertilisers containing traces of Cadmium, Arsenic and Lead. Farmer reliance on these can be reduced by greater use of locally made rock phosphate. Similarly, better regulation of pesticide distribution and use is also needed.
Going a step further, the study has advocated strengthening tobacco regulation to protect people from exposure to Cadmium through passive smoking. This should add to the already strong case against tobacco.
The humanitarian crisis of CKDu has reached such levels, notes WHO, that urgent remedial actions are needed even as researchers continue their investigations.
“Translating available research findings into action should not be delayed. Implementing multisectoral measures to people’s (especially children’s) exposure to nephrotoxins is a top priority,” said Dr Mendis. “Follow-up research should not be a barrier for implementing WHO recommendations.”

It was a national study, clarifies Health Ministry
The national research project on CKDu was co-funded by the World Health Organization (WHO) and Sri Lanka National Science Foundation (NSF). Comprising 11 studies, it is most comprehensive investigation on the topic so far, and involved dozens of local researchers and senior public health officials.
Research teams measured arsenic, cadmium, lead, selenium, pesticides and other elements, often linked with kidney failure, in biological samples from CKDu patients from three endemic areas (Anuradhapura, Polonnaruwa and Badulla). They compared the data with control groups from the endemic areas and a non-endemic area, i.e. Hambantota. They also analysed food, water, soil and agrochemicals from all the areas for the presence of heavy metals such as Cadmium, Arsenic and Lead.
The research findings were formally released in mid 2013. They were also published as a scientific paper in the international medical journal BMC Nephrologyin August 2013. The full paper can be accessed free online at: http://www.biomedcentral.com/1471-2369/14/180
“This is a national study carried out by our own experts, with World Health Organization (WHO) providing technical advice and part of the funding,” said Dr P.G. Mahipala, Director General of Health Services at the Ministry of Health.
He clarified: “It is not correct to refer to this study as a WHO study.”
Don’t exaggerate Lanka’s kidney disease – by Nalaka Gunawardene – Ceylon Today, 28 Dec 2013
In this week’s Ravaya column, I pay another tribute to Dr Cyril Ponnamperuma, Lankan biochemist who was one of the best known and most accomplished scientists produced by Sri Lanka.This explores the time he spent in Sri Lanka in the late 1980s, working as Presidential Science Adviser and Director of the Institute of Fundamental Studies (IFS) in Kandy.
