Food Security and Famine Prevention (Africa)

I compliment my hon. Friend on her speech. She mentioned land purchases by western farming interests and other wealthy countries—some in the far east, in Asia. Does she not think that there has to be some change in the mechanism so that it is impossible for wealthy countries to buy and take very valuable land which they then keep for themselves and for private food exports to themselves, leaving the people surrounding them in Africa in the very vulnerable and dangerous situation in which they are now?
