Governments, businesses and charities make a historic pledge to end undernutrition in our lifetime at Saturday's Nutrition for Growth event.

Speaking at the event, the Prime Minister David Cameron said beating hunger can only be achieved by doing things differently - different in terms of business, science and government. He was joined by the Brazilian Vice President Michel Temer and the Children’s Investment Fund Foundation president Jamie Cooper-Hohn at the high level summit in London of developing and developed nations, businesses, scientific and civil society groups - all committing support to a historic reduction in undernutrition.

Donors secured new commitments of up to £2.7 billion ($4.15 billion) to tackle undernutrition up to 2020. The UK committed an additional £375 million of core funding and £280 million of matched funding from 2013 to 2020.

Speaking at the event International Development Secretary Justine Greening said:

"Undernutrition is stopping children and countries from reaching their full potential, accounting for the loss of billions of dollars in productivity. A strong and healthy workforce is vital if a country’s economy is to prosper. This means business and science taking a lead in fighting for good nutrition because we understand that better nutrition is the smart way to tackle extreme poverty, child mortality and economic underachievement."
