UN MDG Summit 20-22 September 2010
"It is clear that improvements in the lives of the poor have been unacceptably slow, and some hard-won gains are being eroded by the climate, food and economic crises," UN Secretary-General Ban Ki-moon in the foreword to the Millennium Development Goals Report to the Summit.

The Climate Change Challenge
• Climate change will worsen the living conditions of farmers, fishers and forest-dependent people who are already vulnerable and food insecure
• Rural communities ... face an immediate and ever-growing risk of increased crop failure, loss of livestock, loss of fisheries ......
• Hunger and malnutrition will increase
FAO 2009

The Big Disconnect
Development and global change have been addressed, researched, and funded as unrelated issues

Food Security ...
is achieved when “all people, at all times, have physical and economic access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life" (FAO, 1996)

Main Elements of Food Systems
FOOD UTILISATION
FOOD ACCESS
• Affordability • Allocation • Preference
• Nutritional Value • Social Value • Food Safety
FOOD AVAILABILITY
• Production • Distribution • Exchange

We are asking for a wide range of agricultural sector actors to change their behavior, to innovate, under conditions of incomplete and un-integrated markets, asymmetric information & missing insurance and credit markets
