The challenges for Africa are huge: it is projected that by the year 2050 the population will double to 2 billion people while, at the same time, the land available for cultivation will decrease by two thirds. 
These two factors combined raise the question of how to produce food and nutrition for the growing population. Moreover, this will also affect the development of the volatile African economy, since 65 per cent of its labour force and 32 per cent of its gross domestic product currently come from the agricultural sector.
