For its annual World Food Day (16 Oct 2008), the UN Food & Agriculture Organisation (FA0) rightly focuses on the 923 million people suffering from malnutrition in the South - highlighting climate change as the key factor threatening their long-term food security.  In the short-term, rising oil prices have led to increasing food costs and scarcities, provoking riots in over a dozen countries from Burkina Faso, Haiti, to Mexico. The diversion of land for biofuel crops has also been a factor - with the world’s largest grain producer and exporter, the USA, diverting nearly 20% of its harvest to feed cars, rather than people.  
"Global warming is already underway and adaptation strategies are now a matter of urgency, especially for the most vulnerable poor countries. Hundreds of millions of small-scale farmers, fishers and forest-dependent people will be worst hit by climate change. Adaptation strategies, especially for the most vulnerable poor countries, where most of the over 920 million hungry people live, need to be urgently developed, reviewing land use plans, food security programs, fisheries and forestry policies to protect the poor from climate change," Alexander Mueller, FAO Assistant Director-General for Natural Resources Management and Environment Department.
