Next week's G8 summit has turned global attention to combatting malnutrition. It is a long-overdue opportunity to reinvigorate agricultural development, funding for which has been largely stagnant for two decades.
David Cameron told the World Economic Forum in Davos at the beginning of the year that the priority for his chairmanship of the G8 would be tax transparency. Development agencies like Concern Worldwide have taken the Prime Minister at his word.
The UK, as one of the richest countries in the world, has the power and resources to act both at home and abroad. We do not have to choose between the two. And, central to the IF Campaign, we must also tackle some of the systemic causes of hunger.
Imagine if, this evening, the entire population of the United States, Canada, Australia, Britain and the rest of Europe were going to bed hungry. And not just tonight, but one week after another.

Harne Waddaye, a 60-year-old grandmother, digs for food in the bare earth outside the small village of Louga in the African country of Chad. She is raiding ant nests for the grain they have stored. The few grains she is able to gather will go along with the leaves from trees her daughter collects to feed her four children and six grandchildren. It is a meagre fare.
As next week's G20 summit approaches, David Cameron will be heading off to Mexico to join other world leaders in discussions on how to stop the food crisis that already means Fatou is just one of a billion people going hungry.

That income also - somehow - has to cover transport, education, clothes and health costs.
We need food security at home and abroad, and greater transparency in how food commodities are traded globally, as Oxfam and others are calling for.
