The high and volatile food prices that triggered a renewed interest in food security since the 2008 – 0 9 crisis are expected to continue due to several factors that include the impacts of climate change. Current policy prescriptions focus on food production; however, a broader approach based on food systems is more appropriate as it encompasses all aspects of food production, storage, dist ribution and consumption, all of which will be affected by climate change and especially by the growing frequency and severity of extreme weather events. As most low - income groups in both rural and urban areas are net buyers of food, access and affordabili ty are central concerns. There is also a need for more attention to urban food security .
The 2012 Human Development Report for Africa explores why dehumanizing hunger remains pervasive in the region, despite abundant agricultural resources, a favorable growing climate, and rapid economic growth rates. It also emphasizes that food security – the ability to consistently acquire enough calories and nutrients for a healthy and productive life - is essential for human development.
