NAIROBI, Jan 16 (IPS) - As hunger and food insecurity deepen, Africa is confronting an unprecedented food crisis. Estimates show that nearly 282 million people on the continent, or 20 percent of the population, are undernourished. Numerous challenges across the African continent threaten the race to achieve food security; research and innovative strategies are urgently needed to transform current systems as they are inadequate to address the food crisis.
