Africa has remained the most food insecure continent in the world, with approximately one in four people undernourished. Over the years, most African governments have focused on increasing production to meet the food and nutrition needs of the ever rising population which is estimated to reach 2.5 billion by the year 2050. Indeed, most of the strategies for food and nutrition security have been focused more on extensification and intensification increased use of agro-inputs. However, these approaches to FNS are challenged by the limited and inelastic production resources including land, water, energy, agro-inputs. Current food production systems are unsustainable and climate change poses additional challenge to sustainable agriculture in Africa.
