Renewable energy: Some issues

Published

on

At the outset, I must confess, it is with the expectation of severe criticism from those interested that I broach this subject. It is known that wind is interconnected with the sun. Firstly, let me start with the basics, which some experts seem to overlook, and hence fail to explain, as the sun unevenly heats the surface of the earth, air rises and sinks resulting in high and low regions of air pressure, and in the surrounding area air moves in to replace it, causing wind. The more pressure changes over a given distance, usually the faster the wind will be.

Solar Power

When calculating the land area needed for a solar power plant installation, one must look at things that will consume space in the facility. Two main items that consume space are the solar panels and the structural components. It is said that a one-megawatt (MW) plant requires approximately four acres when using crystallised technology. When using thin-film technology, a 1 MW plant will require four to five acres of land. In other terms, each kilowatt (kW) of solar panel requires 100 square feet of space. Considering that the extent of land in Sri Lanka is 65,610 km2, and the population over 21 million, can such a large area be allocated? Apart from the large extent of land, it would mean deforestation, destroying indigenous vegetation to the point of extinction, and also wildlife.

The other serious aspect is, as plants and trees do not grow under these large panels, oxygen and carbon dioxide produced by the vegetation will be reduced, and will not enter the atmosphere. I need not stress the importance of how essential oxygen is for all living beings; animals and plants, to exist on this planet. Isn’t reducing this vital requirement suicidal?

There is also a proposal to have floating solar panels over hydropower reservoirs and lakes. Have they considered the impact on aquatic life; water plants and fish? In this respect, George L. Clark of Biological Laboratories, Howard University writes, “Light is a limiting factor for aquatic plants and animals. Every schoolboy knows that light is required for the growth of green plants and that all animals, including ourselves, depend directly or indirectly upon the plants for their food supply. It is not so obvious, however, that exactly the same situation is encountered in the aquatic habitat. The ultimate source of energy for all the multifarious life in the sea and in every body of freshwater is sunlight. Furthermore, most fish and many types of animals need enough illumination to see – at least part of the time – to catch their food, to avoid being caught themselves. But light does not penetrate into the water indefinitely; it is absorbed by the water itself and further reduced by sediment and by stains. The aquatic biologist is thus concerned to know how much light exists at various depths in rivers, ponds, lakes, and in the ocean itself, and what are the maximum depths at which the fish can see and at which the all-important green plants make a living.”

Apart from aquatic life, there are other aspects to be given serious thought, such as inland freshwater fishing, water sports such as boat racing, which is a tourist attraction and also landing of amphibious planes. The only advantage cited by those who advocate floating solar panels is the saving of 20 percent of water, through the prevention of evaporation, which will help farmers and hydropower generation. Another factor that should be given due consideration is that with vaporized water not rising from the reservoirs, will the rainfall in these areas be affected, streams and rivers in catchment areas go dry and will the weather patterns be subject to change? If so, what is gained by saving 20 percent of water in reservoirs which will be lost if the rains fail in these areas, or are reduced? Under the circumstances, in this Island of ours, it is best to concentrate on and promote local companies and individuals to install rooftop solar panels in houses, hotels, garment factories and other similar business organizations, granting certain tax concessions for the import of necessary components, which will, in turn, allow the Ceylon Electricity Board (CEB) to purchase power at a lower rate.

Wind Farms

Although wind farms take a lot of land space, it does not require clearing of vegetation around it, as cultivation could go on as usual. However, it makes it difficult to predict exactly how much electricity it can generate over time if the wind speed is too low at any given time. Another problem is noise. As wind turbines are built on elevated platforms, they can mar scenic beauty and also harm birds and other creatures that fly.

Biomass

Burning biomass produces similar greenhouse gases to burning of fossil fuels, such as coal. Greenhouse gases contribute to rising global temperature. Burning biomass also releases other pollutants into the atmosphere. These pollutants include particulate matter and nitrogen oxide. Biomass generated electricity can also have an impact on the environment in other ways. For example, cutting down trees can lead to deforestation. Growing plants to use as biomass can have an impact on soil quality and water usage. Indigenous vegetation will be lost, as mentioned earlier and valuable species will be lost forever. With this, the question arises, whether biomass is worse than coal. In my opinion, biomass is the infancy stage of coal. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Surfing the internet, I came across another article titled ‘Carbon Emission from Burning Biomass for Energy’ under the strapline ‘Is Biomass worse than Coal? Yes, if you are interested in reducing carbon dioxide emission any time in the next 40 years.’ It is claimed that Biomass is a ‘low carbon’ or ‘carbon neutral’ fuel, meaning the carbon emitted by biomass burning won’t contribute to climate change. But biomass-burning power plants emit ‘150 percent the CO2 of coal and 300 to 400 percent the CO2 of natural gas, per unit energy produced’. The other disadvantage is the large acreage required to plant any quick-growing trees for use as biomass. Can an Island like ours allocate such an extent of land in the face of a growing population? It was reported that a biomass plant at Walapane in Nuwara-Eliya District had to close down due to difficulties in collecting plants from villagers from their home gardens and transporting them at much cost.

I must confess the contents of this essay have been obtained by surfing the internet for the benefit of those interested, both foreign and local.

In conclusion, the question arises as to whether we are headed in the correct direction in solving energy needs. Certainly not. What we are attempting is the destruction and vandalism of natural endowments and assets, to feed an ever-rising population. It is this factor of overpopulation, which should be tackled, and solutions found for sustainable development and healthy living. The answer is stemming the population explosion by educating the masses in birth control methods, to alleviate poverty and improve health care in addition. Unfortunately, the efforts of the World Health Organisation (WHO) have failed due to religious, national, racial and caste-based battles for supremacy, to beat the other by having a larger community. It will be interesting for readers to know what researcher and novelist, Dan Brown, has written in his book Inferno, “‘Did you know that if you live another 19 years, until the age of 80, you will witness the population triple in your lifetime. One lifetime—a tripling. Think of the implications. As you know, your World Health Organisation has again increased its forecasts, predicting there will be some nine billion people on earth before the midpoint of this century. Animal species are going extinct at a precipitously accelerated rate. The demand for dwindling natural resources is skyrocketing. Clean water is harder and harder to come by. By any biological gauge, our species has exceeded our sustainable numbers.

And in the face of this disaster, the World Health Organisation—the gatekeeper of the planet’s health—is investing in things like curing diabetes, filling blood banks, battling cancer.’ He paused, staring directly at her. ‘And so I brought you here to ask you directly why the hell the World Health Organization does not have the guts to deal with this issue head-on?’ Elizabeth was seething now. ‘Whoever you are, you know damned well the WHO takes overpopulation very seriously. Recently we spent millions of dollars sending doctors into Africa to deliver free condoms and educate people about birth control.’

‘Ah, yes!’ the lanky man derided. ‘And an even bigger army of Catholic missionaries marched in on your heels and told the Africans that if they used the condoms, they’d all go to hell. Africa has a new environmental issue now—landfills overflowing with unused condoms.’”

What we should do is concentrate on stemming the ever-increasing population growth rate, by educating and convincing the people of the harm to the environment and also poverty. This should be done either by enacting laws to promote small families and as said earlier by educating the masses. One example is China, which has vast areas of uninhabited land, yet they curtailed population growth through the one-child policy. The result is that today China is a world power, in terms of science, technology and economy.

It is time for a course correction lest it should be suicidal. Or, we can opt for the much-hyped sustainable development, which also includes population explosion.

We condemn casteist violence at Vaddukoddai; We resolve to fight against all forms of caste oppression

Published

on

The Jaffna People’s Forum for Coexistence strongly condemns the casteist violence unleashed on the oppressed community in Arasady, Vaddukoddai, in Jaffna, on the 19th of September 2021 by a group of dominant-caste youth and men. Many members of this community were injured during this violence. One person’s finger was slashed off. Houses, properties, work equipment and workshops belonging to the members of this community were vandalized.

Caste-based violence has a long history in Vaddukoddai and its neighbouring villages such as Ponnalai, Thunaivi, Koddaikaadu and Muthali Koviladi. The incident that happened in Arasady cannot be viewed merely as an incidental use of physical force by one group on another or a conflict between two groups, as sections of the media try to portray it; it is a violent manifestation of deep-seated caste prejudices existing within caste-based hierarchies and socio-economic dimensions of caste oppression that characterise Jaffna society.

Caste Structure around
Arasady Village

Arasady, where this violence occurred, is a village that is geographically and socially divided along caste lines and caste-based boundaries. The villages in and around Vaddukoddai, where marginalized communities live, do not have paved roads. The sand pathways in these villages become clogged with flood water during the rainy season. Some of the houses lack basic facilities.

Parents from these communities complain that their children are discriminated against in the schools at Vaddukoddai. Even in places of worship, the community faces marginalisation and exclusion. The religious and social organisations that operate in Vaddukoddai are organized along caste lines. In everyday life, the marginalized people from this area face casteist slurs from those of dominant caste groups.

Casteism, Resistance
and Resilience

The oppressed communities at Vaddukoddai have been affected by poverty. Many of them work as daily-wage labourers. Some of them do not own inhabitable or cultivable land. Children from some of these families have had to drop out from school due to poverty. This community has faced systemic marginalisation in education and economic development, transportation and infrastructure facilities and culturally as well, for many decades.

Some members of this community were among those most severely affected during the protracted civil war in the country. They were displaced from Jaffna during the 1995 Exodus. Some of the displaced people later moved to the Vanni and had to live through the horrific violence that unfolded during the end of the war, before returning to Vaddukoddai a decade ago. In the post-war years, the state did not offer any robust programs for the socio-economic upliftment of this war-ravaged community. Some members of the community, in their effort to make ends meet, fell into the debt-trap of predatory microfinance companies. The violence they faced in September has compounded their sense of marginalisation.

Historically, caste chauvinism is transmitted from one generation to another; economic policies of the state do not take into consideration the ways in which caste oppression works in society; and Tamil political leaders ignore, downplay and conceal casteism prevailing within the Tamil community. These factors and forces have led to the current predicament of the oppressed communities in Jaffna. We need to understand the violence at Vaddukoddai as a part of these continuing social, political, economic processes of caste-based oppression and exclusion.

Caste struggles have been fought and the oppressed caste communities have risen against their oppression. They have fought, negotiated, compromised, and individually and collectively challenged the oppressive conditions of caste domination. The community at Vaddukoddai that faced casteist violence has shown great resilience and courage in overcoming caste-based marginalisation over the years. Their will to survive and to survive with dignity and their ability to recalibrate their struggles for the future bear testament to this. Their perseverance, resistance and community building and the openings created by the larger and everyday struggles against casteism in the North have made possible changes, mobilities and progress in geographic, social and economic terms.

Taking pride in all that they have achieved as individuals and as a community against all odds stacked against them, the people collectively and continuously strive for a dignified life for their community. They have faith in life and persevere to ensure that their children will not face the problems they and their ancestors had to face. Even though the recent violence has caused fear among the community, they are confident that they will overcome the threats they face in a collective spirit and by building alliances.

Justice for the Community and Eliminating Caste Oppression

The measures taken by the Police to ensure that those affected by the violence at Vaddukoddai have justice are unsatisfactory. It is even alleged that the Police on some occasions allied themselves with the dominant caste group that perpetrated this violence. The Police have not done enough to bring to book many who were involved in this violence. Politicians and lawyers associated with the perpetrators and others who are hesitant to challenge casteism head-on are sending feelers to the affected community to dilute the latter’s demands for justice and their democratic struggle against casteism. Such insincere attempts to weaken the community’s spirit of resistance should end immediately.

The Vaddukoddai incident has brought us to the crossroads of anti-caste activism and a reappraisal of how we look at the societies we live in. We need to acknowledge and struggle against the deep economic, political and social divisions that are amidst us, signified most potently by caste. As the community in Vaddukoddai rises against this latest infraction of their right to inhabit place, the right to work and live in society, we as a whole must act in solidarity with them. While condemning the casteist violence in Vaddukoddai, we commit ourselves to fighting and resisting all forms of caste oppression and building a social and political culture where there is no room for caste-based oppression.

The Jaffna People’s Forum for Coexistence was inaugurated following the Easter Sunday attacks of 2019 with a view to promoting coexistence and social justice among different ethnic and religious communities.

Following the casteist violence at Vaddukoddai in September 2021, the members of the Jaffna People’s Forum for Coexistence visited Vaddukoddai and held discussions with the people who were affected during this violence. The Forum met on the 22nd of October 2021 to discuss the violence and the challenges faced by the oppressed community in the aftermath of the violence. A decision was made at this meeting to issue a statement condemning this violence.

Prof. Anthony Joseph Weeramunda

An Appreciation

An online commemoration event was held last week, organised by the Sociology Alumni Association of the Colombo University, in association with the Department of Sociology there, to appreciate the contribution that Professor A.J. Weeramunda, who passed away three months ago, made to the Department, training of undergraduate and graduate students and sociological and anthropological research over three decades, since the early 1980s. The well attended event showed the wide ranging impact that his presence and work at the University of Colombo has had on his students and colleagues there, over several decades. What I attempt in this short narrative is to highlight a few significant contributions he made to promote critical social science research in Sri Lanka, based on my own observations, over three decades, when I had the opportunity of closely interacting with him as one of his colleagues in the Department.

Professor Weeramunda became a regular staff member in the Department of Sociology, in the early 1980s, and was already the Head of Department when I moved in there, in 1985 as a young lecturer. Though he was much senior to me, at the time, I immediately felt that he did not worry about his seniority in dealing with his colleagues. He began to address me affectionately as Siri, giving me the tacit understanding that I should reciprocate by addressing him by his first name, Joe. No doubt our graduate studies for several years, in two broadly similar western countries, made the above interpersonal adjustment that much easier. But, then it did not take long for me to realise that he was a kind, unassuming, friendly, informal, humorous and down to earth  person who did not worry about hierarchical values.

Joe Weeramunda was not just another academic. While his commitment to serious academic research and dissemination of knowledge was quite clear throughout, his personality has been multifaceted from his undergraduate days. Though his main area of study at Peradeniya was English, he also had an interest in the Sinhala language, performing arts, drama, and even religious activities in the area of his own faith. Exposed to the work of such well established, eminent academics, like Edmond Leach, S.J. Thambiah, Gananath Obeyesekere and Ralph Peiris, already as an undergraduate, his interest in Anthropology and Sociology no doubt grew rapidly. His decision to pursue his post graduate studies in Anthropology at Washington University, in the United States, was no doubt a reflection of the above interest. On the other hand, his subsequent research interests that he pursued after his post-graduate studies indicated an influence of even a wider spectrum of scholars.

Several years prior to joining the Colombo Sociology Department, as a permanent staff member, in 1985, I was a visiting lecturer there for several years. It was during this period, in 1984, Joe worked with several Sri Lankan and foreign academics, notably James Brow, Mick Moore and Gananath Obeyesekere, to organise a landmark conference at Anuradhapura on Symbolic and Material Dimensions of Agrarian Change in Sri Lanka. ‘This conference brought together many Sri Lankan and overseas scholars with diverse theoretical orientations. This was necessary given the longstanding theoretical controversy over symbolic versus materialist orientations among anthropologists and sociologists at the time. In the Colombo Department of Sociology itself, this division was evident. While Dr. Newton Gunasinghe, another well known academic there at the time represented the Materialist school, as was evident from his research and writings on agrarian relations in Sri Lanka, while Joe was more tilted towards the symbolic. When a good selection of papers presented at the above conference was published by Sage India in 1992 as a collection of essays edited by James Brow and Joe Weeramunda under the title: Agrarian Change in Sri Lanka, it immediately attracted the attention of many  scholars and students alike, in both Sri Lanka and overseas. I was fortunate enough as a younger academic to have had the opportunity of contributing to both the conference  and the publication.

As a well trained liberal arts scholar and an Anthropologist, Joe displayed a keen interest throughout in conducting field research on diverse themes over several decades. He was convinced that undergraduate students should not only be exposed to theoretical discourses within the subject but also undergo practical training in conducting ethnographic research in the field. This would have been been at least partly due to his own exposure to field  research conducted by senior scholars there with the involvement of undergraduate students at Peradeniya. So, he naturally tended to encourage students to spend time in the field, both in rural and urban areas. For instance, even the academic curriculum was modified to some extent to accommodate this aspect of undergraduate education in sociology in Colombo.

The Department of Sociology in Colombo was fortunate to establish an academic exchange programme with Leiden University in the Netherlands, in 1985, when Joe was still the Head of Department. This programme opened up many possibilities for promoting sociological and anthropological research on a range of themes, including the growing phenomenon of labour migration from Sri Lanka to the Middle East. Many academic visitors from the Netherlands actively took part in research activities for a number of years in collaboration with members of the academic staff and students in the Department. These research activities no doubt pleased Joe as he could see his students playing an active role in field research as part of their studies.

Joe Weeramunda served the University of Colombo for about three decades. He made a highly significant contribution to the development of the academic and research programmes in the University’s Department of Sociology. He took an active interest in the development of research and other skills of the students. His very friendly and informal ways of dealing with his students helped him to develop a good rapport with students. As many of his former students attested at the commemoration event, he was not just another university professor for them. It is no doubt his multifaceted personality that appealed to them, turning their experiences as undergraduate and postgraduate students into lifelong memories.

I, as one of his colleagues in the Department for three decades, would remember him not only as a brilliant scholar but also as a  good friend and a humble, down-to-earth person.

What to do with political ‘dishonourables’?

Published

on

Everybody, it seems, is appalled by the attraction of politics as a haven for the Intellectually challenged. It is revealed that some 60 % or something, in Parliament (Our Head Office for Democracy), do not boast of six passes at the “O-Level”. The actual numbers are unimportant, because even one (in 225) is excess. (Please ask the peons who scuttle around the chamber, keeping the water bottles of MPs recharged. Their percentage will surely be higher). For their contributions to State performance, even tapeworms would probably be more generous in the returns to their hosts.

But give it to the Honourables and their ingenuity, they use a very fine method. This is to bestow, as many as possible, Doctorates – thereby raising the average – assuming that credits are transferable! Suits me, as my conscience does not permit the use of “honourable”, I feel more comfortable with Dr. – at least I would be right 50% of the time, and still rising!

It has often been stated that members of the Singapore Legislature are among the highest paid in the World, but as the Chinese itinerant cloth seller of yore would say to the bargaining housewife, “Yes, m’am, but good things no cheap, cheap things no good”. It has to be noted that in the Singapore comparison, the much-envied numbers are “absolutely all-inclusive”. No housing allowances, cars, petrol, attendance fees, subsidised meals, light bills, telephones, medicals or any other. I believe that the legendary Lee Kwan Yew, generously conceded that ‘any of his cabinet’ was at perfect liberty to dwell in the swankiest neighbourhood, or own the poshest vehicle – but at his cost.” The recently retired German Chancellor, Angela Merkel was asked, “Why are you always clad in the same overcoat? Do you not own another?” Retorted she, “I am a public servant and not a fashion model!” What modesty, what class!

It would be unrealistic to expect the electoral process to operate on the basis of an objective assessment of the merits of contending candidates. Equally, it cannot be denied that the performance and contributions of the successful are demonstrably unequal.

However uncomfortable it may be, some means of recognising and giving effect to the indisputable principle that “Performance must match emoluments” or “Service must match reward”. There is no simple method of achieving this manifestly fair goal. May one suggestion be useful as a working proposition? Every member should draw as emolument, their last drawn salary or fee, (supported by the latest Income Tax declaration), multiplied by a pre-agreed factor of five, 10 or even 20 (or whatever), as all-inclusive remuneration. Beyond that, no other payments or perks, hidden or otherwise whatsoever. It would be a great index of sincerity, if such a proposal were to be seriously considered (or voted upon, by a secret ballot if desired). This might help us to separate the grain from the chaff, and go some way in raising the public esteem of Parliament, from its unhealthily low present position.

One other compelling benefit will be that the indefensible crime of hawked vehicle permits would cease. We cannot afford to have criminals in our Hallowed (or Hollowed?) Parliament, can we? If this suggestion secures approval, a great improvement in quality of debate, behaviour, decorum and usefulness will soon manifest.

The vehicle permit issue deserves a further mention, because one justification is laughable and serious at the same time. One person close to the political centre and thus reliable, argued that contesting an election was very costly, and beyond the reach of the capable and the untainted. Only drug kingpins, smugglers, cheats, procurers and similar criminal types could afford such an outlay. All agree that an improved composition of Parliament membership is urgently needed. Therefore, the honest ones selected, deserve some means of recovering their costs. So, what could be wrong in their selling a privilege – vehicle permit, petrol coupons, fake medical claims, etc.? And if I may add, “Take-away packs” of the heavily subsidised restaurant grub?

But some problems arise with such a cozy attempt to justify this clearly improper practice. The major problem is, why did not this principle of “The end justifies the means” apply in the case of that poor woman who attempted to pinch two packets of milk powder to feed her starving kids, or that girl arraigned for picking a few fallen coconuts to help pay for her class books?

One may well be tempted to ask “Why should not those who make the Law (Legislators) be also permitted to break them?”. Or, in the case of politicised appointees, “Why should not the person who appoints, be denied the right to “disappoint”? Neat but not logical nor moral enough. Two wrongs do not make a right. Or, do they?
