This new edition of Save and Grow comes following the Rio+20 Conference in June 2012 and the launch of the Zero Hunger Challenge by the United Nations Secretary-General, Ban Ki-moon. The challenge has five elements: guarantee year-round access to adequate food, end stunting in children, double small farmer productivity, foster sustainable food production systems, and reduce food waste and loss to zero. In assisting countries to adopt Save and Grow policies and approaches, FAO is responding to that challenge and helping to build the hunger-free world we all want.
