can ensure that the industry is recognised as a vital part of the British economy, and that it is a worthwhile career choice. I am happy to discuss that matter further with my hon. Friend.

My hon. Friend the Member for Sherwood (Mr Spencer) referred to allotments. I was just coming on to the issue of growing food in our schools, which is equally as important. We need to ensure that our schools are part of this project. The Secretary of State recently launched the food growing in schools task force. The task force, which is led by Garden Organic, will make recommendations on the need for a food growing area to be integrated into every school in the UK. I have had many dealings with schools that are twinned with individual farms. Pupils not only go on physical visits but, through DVD technology, the farm can go to the school. Such twinning arrangements allow for children to be frequently updated on how the crops or livestock are progressing, so that they can learn more about how food is produced.

My hon. Friend the Member for South Thanet was right to refer to food prices. Of course we acknowledge that some people struggle to afford a healthy diet. The Government provide a means-tested nutritional safety net for extremely low-income families through the Healthy Start initiative, which offers vouchers that can be spent on milk and plain fresh and frozen fruit and vegetables at participating retailers. It supports more than half a million nutritionally vulnerable pregnant women, babies and young children. We are trying to help.

We also routinely monitor trends in the affordability of food through domestic retail food price inflation and movements in the drivers of domestic retail food prices. It is important to recognise an issue that this House often does not understand. Since the removal of production-linked support in 2005, after decades of politicians across the political spectrum demanding an end to the common agricultural policy propping up prices, farm crops and livestock have been traded in a global marketplace. It is those markets that dictate our food prices, along with exchange rates, oil prices and wider commodity issues.

My hon. Friend also referred obliquely to the meeting of G20 Agriculture Ministers. The issue of international trade and price volatility was central to that meeting. I assure the House that the UK will take global leadership on this issue. We are committed to promoting better functioning of agriculture markets to help mitigate future price spikes, and that commitment is demonstrated through the important steps taken towards the development of better-functioning markets at the first ever meeting of G20 Agriculture Ministers.

My hon. Friend referred to the link between food and energy. We, too, recognise the strong dependency of our food supply on energy supply and transport infrastructure. As she suggested, the Government have a co-ordinated approach to the supply and resilience elements of food security. I will not go into great detail about it tonight, but I can assure her that my officials work closely with colleagues in all relevant Departments in response to the risks to our food security and other parts of our national infrastructure. The Department for Environment, Food and Rural Affairs also continues to build an evidence base on all aspects of the food supply chain.

The Government have made a sustainable and profitable food and farming sector the No. 1 business objective of DEFRA. We believe passionately in the industry, which,
