Biotechnology and Food Security

Mark Spencer Excerpts

Wednesday 12th January 2011 Westminster Hall

[Mr Mark Spencer (Sherwood) (Con)]

I am grateful for the opportunity to debate this important issue. I want the debate to be fact-based and to be about the science. I want it to be an unemotional and genuinely open debate about the future of this country’s food security and how we ensure that the people of the United Kingdom are well fed into the next generation. I acknowledge that this issue is not the responsibility of the UK Government or the Minister, but a European Union issue. It is for the EU to decide whether it uses genetic modification and biotechnology to solve such problems. This debate is an appeal to the Minister to push for and facilitate discussion, so that others can join in and we can have an open discussion about how to ensure that this great nation of ours is fed.

I am no historian, but following the second world war Winston Churchill said that this country should never again allow itself to be exposed to the food security issues we faced during that war. We have had two or three generations of consumers who have no concept of what food security is, or what it is like to go to the supermarket and find that a product is not on the shelf. My wife will go to the shop and if the product she requires is not on the shelf, she will storm down to customer services, bang on the desk and say, “What do you mean you haven’t got any paprika?”—or some other wonderful product. My grandmother, however, would go to the butchers and say, “I’d like lamb chops” and the butcher would say, “You can’t have lamb chops. You can have beef dripping because that’s all I’ve got”, and she would have to take it. Consumers now have no concept of what food security is, and it will be a big shock if we find ourselves in those circumstances again.

I turn to where we as a country have come to. My right hon. Friend the Member for Arundel and South Downs (Nick Herbert) said last year that since 1997, the UK dairy herd is down by 22%, which is 500,000 fewer dairy cows. Fresh vegetable production is down by 36,000 hectares; the pig herd is down by 40%, which is 3 million fewer pigs; fresh fruit is down by 9,000 hectares; and the lamb flock is down by 25%, which is 10 million fewer lambs. Despite the fact that self-sufficiency in food production had dropped from 72% in 1996 to 60% in 2008, the Labour Government said in that year that the

“UK currently enjoys a high level of national food security”.

It is true that this country is still able to source and import food very easily, and nobody would stand here today and say that we will ever be 100% efficient in producing our own food. I, like many hon. Members, enjoy bananas, oranges and fruit from all over the world. However, the figures paint the picture of our diminishing ability to feed ourselves, and if that pipeline—the amount of food flowing into the country—were cut for any reason, it would have dramatic effects on our ability to do so.

There are four factors in the world today that will have enormous consequences for this country’s ability to feed ourselves: climate change, the global population, the global economy, and energy prices and our ability to supply energy to the world. I shall take them separately.

There is little debate over whether the climate is changing, and frankly, it is irrelevant whether we agree that that change is man-made or carbon-based. There is extreme weather: we need only look at Russia, which has suffered drought, and at Australia, which is suffering terrible floods at the moment, or at the terrible snow and frost in our country this year and the impact that had on vegetable producers. Trying to harvest carrots and parsnips from frozen ground was an enormous challenge for British farmers, who were trying to put those vegetables on to our plates for Christmas. Extreme weather brings huge challenges and will have a big impact on the cost of food.

Hon. Members who are familiar with commodity prices will know what this summer’s drought in Russia did to the value of wheat. Almost overnight, the value went from £90 a tonne to £160 a tonne for next September’s wheat, simply because the Russian Government said that they will not export any wheat but will retain it within Russia. That pushed world commodity prices up dramatically, which has affected general consumers. When they go to the supermarket to buy a loaf of bread, they find that quite a cost has been added to it.

In 2003 Europe experienced a long, hot summer, which reduced the EU’s agricultural output in that year by 20%. There is a fine line between over-supply and under-supply. We need only be 2% under-supplied for the market to react and push up prices; we will feel that more in future. Farmers need to find new technologies to assist them, so they can cope with the changes in climate.

Secondly, global population will impact dramatically on our ability to feed ourselves. It is predicted that there will be 9 billion people on the planet by 2050. Where is the food to feed that number of people going to come from?

[Julian Sturdy (York Outer) (Con)]

I thank my hon. Friend for giving way and congratulate him on securing the debate. He is right about the huge increase in world population and its impact on food security for the UK and Europe. Does he agree that the only way to tackle this is through new technology and science—for example, research to improve disease resistance and drought tolerance of staple crops, not only in the UK but across the world? We must not close the door on science and new technology.

[Mr Spencer]

I thank my hon. Friend for that intervention. He is correct, in that we need to harness new technologies if we are to solve the problem. I will talk about that a little more later.

We have clearly been effective since the second world war in harnessing such technologies and in scientific advancement. The common agricultural policy, which came out of the post-war period, is often ridiculed as an enormous monster of a policy, but it was probably the most single most effective policy ever devised by politicians. It was designed to feed Europe and was enormously successful—so successful that by the 1980s, we had grain mountains and milk lakes. We all remember those stories in the media.

We have an enormous and growing world population, and we will have to try to feed all those people. It is important to recognise that the amount of land on the earth is not expanding, and we are using land for other things, not only food production. “They have stopped making land,” as they say.

At the same time, the issue is absolutely linked to the global economy. There have always been hungry people on this earth, but all of a sudden, we have countries with people who are not only hungry, but wealthy. On the other side of the globe, the economies of countries such as India and China are expanding, and diets are becoming western. The impact on the European Union will be enormous. In 1985, the average Chinese consumer ate 20 kg of meat a year, but it is now said that they eat 50 kg a year. Across the globe, economies are expanding—in India, the far east, south America and many African countries. Countries are moving in a similar direction to China, which will have a really large effect on our ability to keep ourselves fed.

The third relevant issue is world energy prices and our ability to ensure that we have enough energy. As economies expand, so, too, does their desire to consume energy—a country’s GDP is almost directly linked to the amount of energy it consumes. How will we produce enough energy and how will we do that sustainably? Sustainability is the key. It is all very well saying that we have enough gas and coal to keep ourselves going, but the impact of that carbon will be quite dramatic.

[Jim Shannon (Strangford) (DUP)]

Obviously, the hon. Gentleman’s discussions with constituents will, like mine, have indicated that there is particular concern about the price of fuel—the fuel prices that the farmer pays to run his tractors in the fields. Those prices have also affected the price of fertiliser, which has risen from £100 to £300 a tonne. Does the hon. Gentleman feel, as many of us do, that concern about food prices will rise and that the days of cheap food are perhaps disappearing? We once sourced cheap food from south America, but demand from China, India and elsewhere may mean that our markets for cheap food will disappear. Does the hon. Gentleman share those concerns?

[Mr Spencer]

I thank you for that intervention. Those are exactly the concerns that I am expressing. You sum up very neatly what will happen to global markets. We have been importing from south America, Africa and many other places. When the almighty dollar takes hold, and China tells countries, “Don’t export your meat products to the United Kingdom. Export them to China and we’ll pay you a dollar a kilo more,” producers will naturally say, “Thank you very much, United Kingdom, but we’ll sell to China. We’ll export to you if you pay £1.50 a kilo extra.” That is exactly where the problem materialises.

Energy is very much linked to this issue. As you indicated, the cost of agricultural fertiliser—

[Mr Gary Streeter (in the Chair)]

Order. I am sorry to interrupt the hon. Gentleman, who is making an impressive speech, but there are too many references to “you”. Members should always refer to each other as hon. Members or hon. Friends.

[Mr Spencer]

I am grateful to you for your intervention, Mr Streeter.

World energy prices are very much linked to the issues that we face. The simple fact is that the price of petroleum directly affects the price of agricultural fertilisers and pesticides and has a knock-on effect on them.

Energy production itself requires land usage. Erecting a wind turbine takes out land that could be used for agricultural food production. The erection of a refinery takes land out of agricultural food production and uses it for industrial purposes. More importantly, as we move towards sustainable energy sources, such as bioethanol and biodiesel produced from rape seed, we will be using agricultural crops to produce those biofuels, taking land out of food production and putting it into energy production. That might seem like a wonderful, modern technology and a wonderful, modern thing to do, but when my grandfather started farming in the 1930s, 30% of his land was used to produce oats, which were the energy source for the horses that he used to pull the ploughs. There is, therefore, nothing new in farmers using land for energy production. What has changed, however, is the number of people we have to feed and produce for. The changes will be quite dramatic, and we need to make sure that we have technologies available to assist us.

The Government’s chief scientific adviser, Sir John Beddington, said:

“by 2030 we need to be producing 50% more food. At the same time, we will need 50% more energy, and 30% more fresh water.”

Those are dramatic statistics. If we are to solve such problems, we really will have to set our stall out and meet those challenges. I hope that we all recognise that there are enormous challenges out there.

[Simon Hart (Carmarthen West and South Pembrokeshire) (Con)]

I, too, congratulate my hon. Friend on the way in which he is putting the case. One area of influence that has not been touched on is the UK media’s attitude to some of the topics he has discussed. Does he have a view on whether their attitude, particularly to developing technologies, has been a hindrance and has impacted negatively on our farmers’ ability to meet the challenges he has set out?

[Mr Spencer]

I thank my hon. Friend for that intervention. What he says is true, and the purpose of today’s debate is to have a much more mature, science-based, focused discussion, which looks at the facts rather than the hysteria. My hon. Friend will recall headlines such as “Frankenstein foods”, which do nothing to inform people, and only make them scared of new technologies. To a certain extent, that is human nature. I stand here today unsure myself as to whether these new technologies will assist us. My point, however, is that we need to have the debate, to look at the facts and to explore the opportunities to see whether they offer a solution to the problems we face.

The human race has always been scared of new technologies. If we went back in history to the first time a surgeon suggested doing a heart transplant, we would see the furore that that caused. It was very dramatic to take a heart from one human being and transplant it into another human being. That was quite scary at the time, but it is now run of the mill. As a Member of Parliament, I am lobbied by people who say that we need to improve organ donation and to make sure that we are all informed about it. The technology is accepted and warmly embraced.

To an extent, we are going through the same debate with stem cells, because people are concerned about them and about whether they can assist us. Of course the human race is sometimes scared of change, but we have always been quite adaptable. In the end, we get there, we embrace technologies and we make use of them. That is why we have been so successful as a species at looking after ourselves.

I want to draw attention to Sir Norman Borlaug, who won a Nobel peace prize for his work in changing wheat varieties and improving the way in which we feed ourselves. Many Members have mentioned the fact that we have been able to feed ourselves since the second world war, and we have done a very good job of that. Sir Norman Borlaug was the lead figure in the field. After the second world war, wheat yields were very low. As part of a long and painful process, Sir Norman used a paintbrush to cross-pollinate different varieties of wheat. He was able to take the correct strains from one variety and put them into another. That made the wheat yield vastly more per acre. It also made varieties shorter so that they did not fall over. As I said, we were able to feed Europe; we were able to keep what is now the European Union well fed. That process took a long time. We are talking about tens of years to make advancements in the science.

I am led to believe that genetic modification can speed up that process of genetic change. We have been doing such things for a long time. We have been changing the genetic make-up of those varieties through the long and laborious process of cross-pollination. Genetic modification can speed up that process and lead to advances that will reduce the disease susceptibility of those varieties and make them easier to grow and more drought-resistant. That has to be a good thing. At this stage, it is worth recognising that the genie is out of the bottle. Countries such as the USA, Canada and Brazil are using these technologies. Those crops are being grown in other parts of the world, where technological advancement is starting to move faster than it is here.

It is suggested that yields could increase between 6% and 30% using the same amount of land. If we were able to harness that technology, we could increase yields by 30%. Given the figures and the global changes that we are experiencing, even that degree of advancement might not be enough to keep us all fed to our accustomed level. The hon. Member for Strangford (Jim Shannon) mentioned fertilisers, a subject that will prove important as we move forward. Imagine a technology able to produce a wheat variety that had the same root structure as lucerne, which is nitrogen-fixing. Lucerne—and clover, which is very similar—takes nitrogen from the atmosphere, absorbs it into its leaves and produces nitrates in its root structure.

[Mr Gregory Campbell (East Londonderry) (DUP)]

I congratulate the hon. Gentleman on securing the debate. It is fitting that a debate on food security should be initiated by a Member with the name Mark Spencer. He stresses the importance of new technologies. Does he agree that is fundamentally important that the Government invest in them, to ensure that the farming community can avail itself of the technologies so that the prospect of feeding the population is more easily achieved?

[Mr Spencer]

The hon. Gentleman is correct that we need to invest. We are actually reducing the amount that we are putting into research and development in the industry. We have not been very good at that. This Government are assisting a little bit, but it is a small step back in the right direction. We have not put enough into research and development. The amount that we spend is dwarfed by the amount being spent by other countries around the globe. We are going to lose our reputation and position at the forefront, the cutting edge of those developments and technologies. This country has always succeeded by leading the way. We were the leaders during the industrial revolution, which gave this small nation a global position, making it the Great Britain that it is.

Globally, farmers have earned an extra €34 billion since the introduction of biotechnologies, 44% of which resulted from yield gains and 56% from the reduction of production costs. I mentioned the benefits of nitrogen-fixing wheat. Improving the root structure of wheat would enable it to be grown in other countries, such as central and northern Africa—places where at the moment it is too dry. The benefits would include not only the ability of this country to feed itself, but the chance for African countries to feed their populations and improve their lifestyle. It could also have massive implications for the environment. The amount of nitrates we use could be dramatically reduced, which would assist in the management and protection of the environment. The amount of pesticides that we use could be reduced. I have never met a farmer who likes using pesticides—they are very expensive. Finding a technology that would enable us to spray fewer pesticides on to crops—which themselves could be more disease-resistant—would benefit farmers and consumers.

In the UK, yields of oilseed rape since 1995 have risen approximately 0.5% year on year. In Canada, they are rising 3% year on year, simply because it is making use of those new technologies. Its farmers' ability to produce more from the same amount will make them more competitive than ours.

It is exciting to see technologies open up. Imagine producing an apple that reduced cholesterol or a tomato that prevented bowel or breast cancer. All of a sudden the media perception of “Frankenstein foods” as something to be feared and avoided would be turned on its head. Consumers would be clamouring to make the most of the new technologies and these “wonder foods” that were cures and were helpful. There is a lot of work to be done and there is a lot of speculation; I acknowledge that, but the technologies are there to be explored and could be of great benefit.

There are clearly concerns. The consumer is concerned about these products. We referred to the fact that people worry about change. We need to recognise that and ensure that we take people along with us in an open debate. It is also worth recognising that technologies used in the past have occasionally broken down. There have been mistakes. Those involved in agricultural industries will remember a wheat variety called “Moulin”, which was marketed, but when it came to the point where it should pollinate it did not work. That was disastrous: farmers had zero yields, having grown the crop for a year. We need to ensure that we do this properly, that the scientific evidence is correct and that we explore the technologies in the right manner. The only way to do that is to do the research and the trials. I ask the Minister to assist in facilitating those trials in the UK, so that we can test the water and try out some of the technologies under controlled circumstances, to see if they have anything to offer to solve the problems that we shall face globally.

The organic sector often expresses concern that there will be cross-contamination—that bees will fly from GM crops to organic crops. In the US there is a thriving organic movement and both systems sit side by side. Consumers have the choice of new technology, traditional or organic food, and it seems to work well.

Who is leading the way? I have mentioned the US and Canada, but China is doubling the amount it is spending on agricultural biotech research and development in the next five years. It is currently spending $400 million on research and development—20% of world investment. The European Union will be left behind if we do not step up to the mark, get stuck in and try to keep pace. Genetic modification technology is currently being used by more than 14 million farmers around the world. That is a landmass equivalent to the whole of France, Germany, the United Kingdom and Ireland. It is no small trial. It is happening on the other side of the globe as we speak. More than 2 trillion meals containing GM ingredients have been consumed over the past 13 years without a single substantiated case of ill health.

Given the fuss that we make about peanuts because every now and again someone has an allergic reaction to them, it seems unbelievable that we are not out there in white suits and little masks tearing up peanut fields because of the impact that peanuts have on people’s diets. However, whenever somebody mentions new technology people with placards want to wreck the trials and research.

I appeal to those who feel the need to wreck those trials not to do so, because we need to find evidence that they work and to establish the technology. If those people are correct in thinking that the technology will not work, we need to do the trials to establish the fact so that the technology can be stopped. My appeal to all involved is to engage in the debate; supermarkets, growers, retailers and producers should come to the table to talk it through, to do the research and development and to settle the argument once and for all. If the technology is available to assist us, we need to enhance it.

What is the implication for UK producers and consumers? Clearly, GM is in production and in circulation. Soya, maize and tomatoes are intrinsic to our diet. I put it to Members that at some point we will all have consumed a GM product without realising it—probably as a soya-based product, perhaps in a pizza or in processed food. The country has a choice. Should we go down the same route as the Austrians and be completely GM-free, not having GM and labelling all our food to ensure that we protect ourselves from the perceived problem; or do we embrace GM and label our food so that people can make a clear choice?

If we go down the GM-free route, our farmers and producers may be able to attract a small premium. However, I believe that commodity prices will continue to rise, and that the global economy and the increase in the global population will have an impact.

[Jim Shannon]

Is the hon. Gentleman aware of the work that has been done by universities across the United Kingdom on GM foods, particularly by Queen’s university? They have been in contact with companies and businesses to perfect GM foods and move forward. The advantage that Queen’s university has for those businesses is that everyone gains. Is he aware of that, and if so will he comment on it?

[Mr Spencer]

I am aware that a number of universities are participating in research, and I appeal to those institutions to give the universities the support that they require to continue with it. It emphasises the fact that the United Kingdom has the scientific brains to do this. We have the willingness and the intellectual power. What we need now is a fair crack of the whip—a bit of financial support and some understanding among the population of the technology. We need to debate the matter so that people can understand it and embrace it—or, if it is not the correct route, to say that it has been considered but that it is not the direction to go. The only way to achieve that is through good scientific research, and I am grateful that Queen’s university is involved in that great work.

I return to my scenario. We have a choice. We either go down the GM-free route or we embrace the technology. If we choose to go down the non-GM route, however, it will be difficult to ensure that our borders are GM-free. For example, meat products will be important but we will have no means of testing whether those animals have been fed on a diet of genetically modified feed. UK producers will be producing free-range chickens for the supermarkets, but those birds could be sat on the shelf next to Brazilian chickens that had been fed on cheaper GM wheat and were being sold for £2 less. Will the British consumer know why the Brazilian chicken is £2 cheaper, or be aware that the other chicken is more expensive because it is GM-free? It will be almost impossible to police. As commodity prices start to increase, the consumer’s unwillingness to tolerate or accept new technologies that give them good, healthy, quality food at the right price will diminish over time. That is why we need to push forward and ensure that we are competitive.

Enormous global changes are afoot that are out of our control. The United Kingdom has no control over global population. We have no control over world energy prices. We have no control over the climate; we should acknowledge that the human race cannot control what happens to the weather. However, we are in control of our ability to use the available technologies. We should embrace those technologies, consider them, discuss them and ensure that we are at the cutting edge as we move forward. If we are going to be sustainable, and if we are going to keep ourselves fed, we need to use all the tools that are available to us. I believe that we should explore the prospect of biotechnology being one of the tools that we should be using.
