Biotechnology and Food Security

William Bain Excerpts

Wednesday 12th January 2011 Westminster Hall

[Mr William Bain (Glasgow North East) (Lab)]

It is a pleasure to serve under your chairmanship, Mr Streeter. I congratulate the hon. Member for Sherwood (Mr Spencer) on securing this debate. He made an extremely wide-ranging, comprehensive and thoughtful speech. I also commend the remarks made by the hon. Member for Mid Norfolk (George Freeman), who gave the House the benefit of his expertise in this area.

This debate is particularly timely because of the recent spike in global food prices. Yesterday, the Financial Times reported:

“Global food prices have reached a nominal all-time high, surpassing even the peak seen in 2007-08—when bread riots rocked poorer countries.”

Although rising food prices may be a great inconvenience for consumers in the United Kingdom, they are particularly worrying for the poorer economies, such as Brazil and India. In India and China, food costs account for almost 50% of household outgoings, so the impact of rising global food prices will be particularly badly felt in those countries.

I commend the remarks made by Professor John Beddington about 18 months ago at the sustainable development conference. He said that if we do not take much more intensive action to increase global food production, we face “a perfect storm” of problems by 2030. He said:

“Our food reserves are at a 50-year low, but 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.”

It seems clear that the use of biotechnology and policy across the EU and G20 must focus on producing more hardy crops, less wastage in terms of crop yields and better use of existing water supplies.

In responding to the debate, there are three areas that I want to touch on. The first is biofuels, which the hon. Member for Sherwood referred to. Through my role in a previous life—my first Front-Bench responsibility, as shadow Minister for Transport—I know that the Minister’s colleagues in the Department for Transport are engaged in a consultation on the renewable transport fuels obligation. There is no question but that sustainable biofuel production has a great deal to offer, both to our economic output and to reducing CO₂ emissions. However, we must be careful about which biofuels we support and invest in. The Government have already taken very welcome action on palm oil; however, there are concerns about some biofuel production, including some bioethanol production, which the Institute for European Environmental Policy has expressed. The IEEP has calculated that the indirect effect of the switch from food production to biofuel production could be to take between 4.1 million and 6.9 million hectares out of food production across the EU. As a result, that could lead to between 26 million and 56 million tonnes of CO₂ emissions being put into the atmosphere.

When the Minister responds, it would be useful if he told us what efforts the Government are making to shift investment and support in research and development and other incentives away from first-generation biofuels and into second-generation biofuels, such as cellulosic ethanol, the use of biofuels from algae and the use of woodchip, all of which are much more sustainable means of biofuel production than simple bioethanol production. It is clear that we must do nothing to put small-scale bioethanol producers in difficulty, but we need a real analysis of what large-scale bioethanol production is going to contribute, in order to establish whether it might be damaging overall in our fight against CO₂ emissions. I hope the Government will be able to conduct that analysis in the next few months.

The second crucial point is the importance of increasing investment in agricultural research and development. Work has recently been done by the academic community on this subject. The two authors, one of whom is based at the university of Bournemouth, of a paper I have been reviewing this morning entitled “Agricultural R&D, technology and productivity” make an excellent point about the benefits—in a sense, the disproportionate benefits—that accrue from investing in agricultural research and development by boosting both global food production and the overall investment in science. Since the second world war, increasing agricultural productivity has allowed food output to keep pace with demand, but that link will perhaps not be evident in the next few years.

It would therefore be useful if the Minister told us today what representations the Government have made at EU level about how the EU can boost R and D investment. Such investment must be boosted in the public sector. It is an aim shared absolutely by Members across the House that we want the EU to spend less on direct subsidies and more on investment in science and agricultural R and D. However, the Government must also consider how to improve the levels of private R and D. For example, what discussions is the Minister having with his Treasury colleagues ahead of the Budget to develop new initiatives that will strengthen private companies’ ability to invest in R and D, building on measures such as the R and D tax credit that the previous Government introduced? Also, can he give the House an assurance that levels of agricultural R and D will be higher at the end of this period of government than when the coalition took office?

The scale of the investment that will be needed is staggering. The paper that I referred to says clearly:

“By 2050, the world population is expected to grow…to 9.1 billion…and allowing for increased incomes and changes in diet”—

the hon. Member for Sherwood referred to those changes, including the immense growth in meat consumption in China—

“global demand for food…to grow by 50 per cent by 2030 and 70 per cent by 2050…The estimate”—

for the increase in agricultural R and D investment—

“is 1.34 per cent…per annum.”

That would be a massive step change in the magnitude of investment from current levels.

The Government must address this issue here in Westminster, but frankly, they must also address it at EU level and at the G20. Has the Minister discussed with the Prime Minister the latter’s raising the issue of biotechnology in discussions at the G20 this year? It is clear that if we do not start to increase the levels of agricultural R and D spend now, it will be very hard to meet the targets for increased food production and innovation that will be required by 2050.

The third area that it is important to address is, of course, genetic modification. The hon. Member for Mid Norfolk was absolutely right that the debate about genetic modification must be rational and based on science. However, I depart slightly from the hon. Member for Sherwood’s analysis, in that my understanding is that last year, the EU decided to devolve down to member states the issue of determining whether genetically modified technology should be used. Therefore, GM technology will be an issue for the UK Government to decide on by assessing the best available science, the level of commitment to such technology, and whether they will permit its large-scale roll-out.

Clearly, there is an important national debate that we need to have. Many people in the food production industry and many academics who have looked at the problems we will face have said that there are clear benefits from investing in GM technology, for precisely the reasons, including innovation, that we heard about from the hon. Members for Sherwood and for Mid Norfolk. However, there are also concerns—very reasonable ones—that we must all address about the potential health issues that may arise decades down the line. It is important that we continue to invest in the science in order to gather the best possible data we can get, so can the Minister tell us what levels of investment in research in GM technology the Government will provide by the end of this Parliament?

The title of this debate is “Biotechnology and Food Security”, and it is clear that conventional biotechnologies such as breeding techniques, use of tissue culture, cultivation practices and fermentation have been readily used and accepted. Between 1950 and 1980, before the development of genetically modified organisms, modern varieties of wheat increased yields by up to 33%, even in the absence of fertiliser. Modern biotechnologies used in containment have been widely adopted. For example, the industrial enzyme market in the US reached $1.5 billion in 2000.

However, we now need a step change if we are to produce higher crop yields, make better use of water and increase sustainable food production—without increasing our overall emissions of CO₂ or other greenhouse gases—such that we can meet the competing but necessary objectives of reducing and alleviating climate change, and achieving greater levels of food production.

I hope the Minister can address those points. There is a consensus on the Front Benches about the need to increase food production. I hope the Minister can reassure us that the Government are committed to increasing R and D levels, particularly agricultural R and D, in both the public and private sectors, and that we can move forward together to tackle this issue, which is of enormous interest to our constituents and to people in many other countries across the world.
