Achieving global food security remains a key challenge for the future, particularly given continued population increases, dietary shifts and global climate change. Attention has been largely focused on agricultural intensification as a mechanism for producing more, even though food insecurity in many places is largely an income and distribution problem Also, there has been much less research focusing on the contribution of farming diversity towards achieving food security, despite evidence that more diverse agroecosystems are likely to perform better today under changing environmental conditions.
