Against all odds

The women and I were walking along the bunds of the paddy field, looking for signs of insect damage to our now ripening paddy. All of a sudden we stopped and gazed in horror. In the plot before us, sheaves of paddy lay trampled underfoot. But why?

The Yala season has not been "problem free".

Even with the adverse weather conditions, the plants did not succumb to the drought. We kept faith with our field. We made it look pretty. The chrysanthemums did flower, but the Giricildia branches that we planted on the bunds did not take root. The branches were removed and tossed aside disdainfully by those who used the bunds of the field to cut short their travel time.

But even they could not have willingly wrecked a plot of paddy, just to thwart our efforts! It was unimaginable. So we got into the field to take a closer look at the damage done, and then we saw it - A large bucket of illicit brew, hidden among the paddy stalks, and some other implements. So that explained the state of the field. People had been sitting there in the evening and having a swig by moonlight. Despair and anger were the first of the emotions to surface.

Despair because we had laboured so hard to bring the field to this stage. Anger at the thoughtlessness of some people.

I wanted to bring the miscreants to book. But was stopped by the women, who opted for caution.

As we discussed the situation and a line of action, one of the women whispered: "We are being watched." I looked towards the bend in the road and there stood two men facing our direction. Did the field hide a security alarm? When we stepped into the field I could swear that we were alone. Seconds had not ticked away from the time when we discovered the bucket, to the time we had an audience!

One of the men was supposed to be the owner of the brew; He was a well-known "chandiya" in the village. I was told that the man was not averse to taking a knife, and if we wanted to stay unharmed we would have to overlook it.

But what about the harm he had done to the field? If crops are damaged the village headman should be notified, the police called in, and after an inquiry the offender would have to make good the damage. But here we had to carry the loss, because the people feared the culprit. The offender had served various prison sentences and was not reformed by the experience; instead his activities only seemed to keep alive his past.

The next day the offending brew had been taken away. The incident was history. But my mind keeps visiting the scene - the loss of a perfectly good plot of paddy. Why did he have to choose one of the best plots? Couldn't he have used the dense vegetation of the countryside instead of the field? How can one succeed in this atmosphere?

The phone rings. The news of the incident has reached Colombo. "Hey, why didn't you let us in on the new venture? Such a lucrative business and you cut us out? And how ingenious, you hid it in the field." Trust Colombo to take the edge off the issue. I burst out laughing.

Towards a safer Sri Lanka
Point of view
By Prof. Athula Perera
Biotechnology has been identified globally as the new technology for the new millennium, especially to solve the problems of food production caused by the ever-decreasing availability of arable land, increasing population (expected to increase from around 6 billion to about 8.5 billion by 2030) and dwindling aquatic resources. The FAO predicts an increase in demand for agricultural production by 60%, of which, more than 85% will be in the developing countries. Studies have shown that for every 10% increase in agricultural yields, there is a reduction of about 10% in the number of poor people and a decrease in childhood malnutrition. The American Association for Advancement of Science reports that 1 billion people have no access to clean water, 2 billion have inadequate sanitation and 1.5 billion breathe polluted air. The Convention on Biological Diversity and the UN's Agenda 21 adopted by more than 178 governments at the Rio Earth Summit in 1992 acknowledge that biotechnology can be used to improve food security, healthcare and the environment.

Numerous techniques
Biotechnology involves numerous techniques ranging from the ancient fermentation technology used in brewing and baking, to tissue culture, enzymology, functional genomics, proteomics, DNA fingerprinting for identification purposes and to establish molecular markers for important characters such as stress tolerance, production of biofertilizer, biopesticides, selection of superior microbes, pollution control, conversion of waste, genetic engineering where genes are transferred from one species to another (recombinant DNA technology/rDNA), cloning and gene therapy. Though this technology was first established in the west, China, Japan and India are leading the way in Asia, with Thailand, Singapore, Malaysia, Philippines and Indonesia catching up fast.

Advantages & concerns
There is no doubt that this capability has to be established in Sri Lanka. Every technology comes with its advantages and concerns. Fire, electricity and nuclear energy, for example, are all being used with great care as any of these can destroy life and our planet with ease. Today, every aspect of our lives is considered with much concern and fear, whether it is the birth of a child, drug abuse in schools, air travel, consumption of alcohol, pesticide usage, carcinogenic chemicals, safety of food and even crossing the road on the yellow lines!! Look at Sanath Jayasuriya wearing a helmet, arm guard, thigh guard etc. while 'blasting' the opposition bowlers! Cricket is a risky business, but we did not ban it!

Apex body of experts
In Sri Lanka, various components of biotechnology are being carried out in several institutes with funds obtained mainly from the local funding agencies such as National Science Foundation (NSF), Council for Agriculture Research Policy (CARP) and National Research Council (NRC), although these funds have 'dried up' at present!

Moreover, as biotechnology involves numerous areas of interest, many ministries are involved in formulating and implementing research in biotechnology, including those involved with agriculture, environment and forest, science and technology, economic reform, livestock development, food, health, education, plantations etc. Therefore, there is an urgent need to coordinate all functions related to biotechnology and bring them under one roof without letting it be fragmented as it is now. There is an urgent need to appoint an Apex Body of eminent scientists to coordinate all biotechnological activities in Sri Lanka.

National Priorities
The respective biotechnology committees of NSF, CARP and NRC have already identified priorities in biotechnology for Sri Lanka. The CARP priorities for agricultural biotechnology are especially valuable, as the FAO has identified it as an excellent piece of work. These priorities have been identified in relation to local conditions and are grouped into seven categories as follows.

* Improvement of crop and livestock productivity
* Reduce cost of cultivation of crops and management of livestock
* Biodiversity of Sri Lanka
* Environment
* Genome analysis and transgenics
* Bioinformatics
* Nutrition
Agricultural Biotechnology Centre (AgBC)
The Ministry of Science & Technology has also identified biotechnology as a thrust area for development. It has supported biotechnology through a loan from the ADB for personnel development and capacity building. By means of this programme, the ministry is establishing an Agricultural Biotechnology Centre (AgBC) at the Faculty of Agriculture, University of Peradeniya. It has laboratories for plant, animal and microbial research, as well as tissue culture and bioinformatics laboratories, greenhouses and research fields. The bioinformatics laboratory will form the nodal point for establishing biological databases, linking up institutes locally, regionally and globally in every field related to biotechnology.

The research programmes already initiated at the AgBC, pertaining to national needs, involves DNA fingerprinting of medicinal plants (e.g. bin kohomba), production of hybrid tomatoes and chilli for dry zone farming conditions using molecular markers, identification and selection of superior kolikuttu banana varieties using DNA fingerprinting, study of gene action in salinity tolerant rice, and tissue culture of pineapples and ornamentals, all undertaken by Ph.D. students of the Postgraduate Institute of Agriculture (PGIA) of the University of Peradeniya, whilst about 40 students have completed their training in biotechnology at the M.Sc. level. More and more have registered for more and more training. Research using rDNA technology will be carried out only under strict biosafety regulations, which are in the process of being established in Sri Lanka. The AgBC has also lined up several training programmes for 2003/2004. It also undertakes educational programmes. These will include lectures and group discussions.

The use of recombinant DNA technology has had a profound impact on the development of science and in the production of novel organisms (GMO) and products globally. It involves the transfer of genes across species and has resulted in the production of higher yielding crops resistant to pests and diseases, with better nutritional, health and environmental attributes, as well as organisms with novel capabilities such as cows producing pharmaceuticals in their milk, strawberries carrying fish genes to enable them to be grown in the winter and edible vaccines (hepatitis B) in potatoes and bananas etc. Using this technology it is possible to produce a novel organism with any combination of characters by transferring genes.

Health sector
The use of biotechnology together with the rapidly advancing science of genetics has created a wide range of new tools for use in human disease diagnosis, management and treatment. These tools include gene therapy, DNA-based vaccines and novel vaccine-delivery systems that could stem the devastations caused by HIV/AIDS, malaria and tuberculosis.

Risk assessment
Like the two sides of the same coin, this technique, especially with regard to its application in the production of genetically modified organisms, brings with it numerous advantages on the one side and as many concerns/risks on the other. The concerns include possible allergenic reactions, transfer of the new gene to other non-target plants such as weeds, toxicity to non-target species of insects, birds and mammals, ownership (patents) of the genes (mostly obtained from the developing countries) and their products by a few (in the industrial or developed countries), human disease causing microorganisms developing resistance to antibiotics etc.

These concerns will be addressed by implementing proper regulations such as the Biosafety Regulations that are at present being established in Sri Lanka. In the meantime, all strata of our society should be 'educated' on the pros and cons of this technique and their views taken into account in making national decisions.

It is also an undeniable fact that biodiversity (variety of organisms) is with 'us' in the developing countries and biotechnology is with 'them' in the developed/industrialized countries. If we continue to maintain this status quo, biopiracy ('stealing' of the genes found in our biodiversity) will be inevitable and 'they' will eventually 'own' what we have. It is important, therefore, to 'import', develop (capacity and human resources) and sustain this technology here, so that we will do what our people want us to do and patent our own genes, processes, software etc. This is what India and China are doing with much success.

The World Bank, concerned with safe science, has announced the formation of a global panel to assess the environmental and social risks of all scientific methods used to boost agricultural productivity including the use of GM food, organic agriculture, traditional plant breeding techniques and new farming technologies.

By identifying the concerns that this technology is supposed to bring and by carrying out open, transparent discussions and debates, we will be able to help this technology be applied as safely as possible, without denying our people its potential benefits and without slipping into the backwaters of nowhere, while others around us and the less privileged, forge ahead.
