EUC Report: Agriculture

Lord Cameron of Dillington Excerpts

Monday 6th February 2012 Grand Committee

[Lord Cameron of Dillington]

My Lords, I am delighted to be speaking in the debate in which the noble Lord, Lord Curry, has made his maiden speech. As we have already heard, his CV in the agricultural and rural world is both comprehensive and stellar in quality. It has long been known that there are few to compare with him in terms of knowledge and experience of all parts of our agricultural and food industry, but equally important, to me, is the way in which he understands how all these parts fit together and how important they are to the economic, social, cultural and environmental fabric of life in both our rural and urban communities. I feel sure that we will all benefit from his words of wisdom on many future occasions, as we have done today.

I must first declare an interest as a farmer in receipt of a single farm payment and as a Lawes trustee at Rothamsted Research Station. I also chair the Strategy Advisory Board of the Government’s Global Food Security programme. However, today I want to explain that the problems facing the agricultural industry are global and that the solutions lie not only in pan-European and trans-world partnerships but in a variety of cross-discipline research projects that must cover the whole length of the food chain. Innovation is not just about growing two blades of grass where there was once only one.

Other noble Lords have mentioned the problems facing the world and, if the Committee will forgive a bit of repetition, I should like to put a bit more flesh on the bones of some of them. The first is the growth in the world’s population from 7 billion to 9 billion-plus. The more serious problem here is the fact that the population of sub-Saharan Africa is going to rise from 1 billion to 2 billion over the next 30 years. This is serious because there are very grave agricultural shortcomings there.

Secondly, world GDP is going to rise by 400 per cent between now and 2040. It sounds good but it means that most people will be changing to a more meat-eating diet, with more consumption of resources—much more than with a vegetarian diet. China is a prime example. Over the past 40 years, its arable area has almost halved and its meat-producing area has more than doubled. In spite of that, its balance of payments now suffers from major imports of both milk and beef, not to mention soya to feed its beef herd. In fact, the current annual trade of soya from Brazil to China is the biggest movement of a single food product from one country to another in the history of the world.

Climate change is another threat which has been mentioned by other speakers. The equatorial belt may become too hot to farm and, if sea levels rise, some of our most productive deltas will disappear. With only a 15 centimetre rise, in India alone some 150,000 farmers will be displaced.

Another problem area is world water supplies. Even with today’s population, the reality is that a child dies as a result of poor sanitation every 20 seconds. Total world water demand is projected to rise by over 30 per cent by 2030 and there are problems even now. Many river systems already run dry due to excess irrigation. Indian farmers, for example, are now taking 100 cubic kilometres per annum more from their aquifers than are being recharged by rains. The most important aquifer under China’s grain belt is falling at the rate of 3 metres per annum. In Africa, already people die in skirmishes between tribes over water. The trouble is that water and rivers do not recognise political boundaries. There are between 250 and 300 rivers and lakes in the world that transcend national boundaries. The dangers are enormous.

There is now a realisation that political unrest might be caused by water and food shortages in the future and that these possible conflicts or anarchy represent a greater danger to the world than the actual shortages themselves. The Government’s new co-ordinating research programme is well named as the Global Food Security programme because, while food shortages in the EU probably feel remote to most people, its citizens’ security could well be threatened by nutritional problems in the wider world.

The point of my very brief coverage of some of the future concerns is not only to show how serious they are but to show how multifaceted and global are the issues. These are worldwide problems. We have to ensure that we are all pulling together. We need scientific partnerships and co-ordination not only between research establishments in the UK—and I am very pleased to say that that is happening with this Global Food Security programme—but across the world. We need trans-European co-ordination and information exchange. We need partnerships in the wider world such as with the US, Brazil and China, where some of highest spending takes place.

I like to think that we in the UK can still contribute in scientific excellence, even if our budgets have been slashed over the years. Judging by the international partnerships that already exist, it would seem that others on the world stage share my confidence.

We also need north/south partnerships, so we can all focus on some of the developing world’s problems and at the same time hopefully enhance the credibility and importance of its scientists, particularly in the eyes of its politicians, so that they, too, pick up on the agenda.

As I said at the beginning, the food chain touches on a wide range of disciplines. Clearly, we need soil scientists, plant pathologists and others involved in the actual growing of the crop; we need hydrological engineers to provide us with water; we need mechanical engineers to provide us with efficient machinery; we need veterinary scientists to maximise livestock production while minimising livestock inputs and greenhouse gas outputs; we need a range of biologists and chemists to cut down on waste both before and after harvest; and we need social scientists to cut down on waste at the consumer end of the food chain, mentioned by several other noble Lords. I came across some research recently indicating that every year in the USA, which also wastes 30 per cent of its food at the consumer end, 300 million barrels of oil and 25 per cent of all man-used water go to produce food that is then thrown away. That is a pretty horrifying statistic.

We also need nutritionists to help achieve the right food intake at the right price to prevent millions of youngsters in the developing world remaining physically stunted or cognitively damaged for the rest of their lives. In this respect, many people think the GM debate is all about producing more food for less cost, but to me the most exciting aspect of these potential scientific advances is where the food is being improved for better health. Of the 10 million-plus kids who die each year in this world, 2 million die from shortages of iron, proteins and vitamins in their diet, while, for instance, only 1 million die from malaria. There is much potential for improvement here, and innovation could be at the heart of it.

We need land-use and planning research to ensure that we optimise our production of food and energy from land while not endangering other species and their habitats. Incidentally, that includes the responsible use of our marine environment, a whole area of research that is probably related more to the art of the politically possible than cutting-edge science. We have to get all these scientific disciplines working together if we are to address the perfect storm outlined by our chief scientist. We have to co-ordinate and ensure that there are no gaps in the chain. That is one of the roles of the global food security programme and the strategy advisory board that I chair.

Talking of gaps in the chain brings me finally to one of the conclusions of our sub-committee report which has been mentioned by several noble Lords already. As the Minister is only too aware—and we thank him warmly for his previous interest in this subject—there is no point in doing any science unless the information gets out to the practitioners, nor will the science be of much use unless the scientists have learnt what is needed from the practitioners. I chair the All-Party Parliamentary Group on Agriculture and Food for Development, which has recently produced a report on African agriculture called Growing out of Poverty—for all those interested, it can be found in the Printed Paper Office. During the evidence-taking sessions, we were again and again reminded that the greatest poverty in Africa is a poverty of information, yet agricultural extension services remain absurdly underprovided for in almost all African and other developing countries. Furthermore, as Sub-Committee D discovered, this underprovision is not limited to Africa but is only too apparent across much of the UK and EU. As others have said in this debate, this situation needs to be urgently rectified if the recently revived interest in agricultural and land-use science is, if you will excuse the pun, to bear fruit.
