Global Environmental Change and Food Security

Attaining food security for all is clearly more complicated than just producing more food. Besides food production, food availability and food affordability are critical prerequisites for ensuring food security. Strongly influenced by social, cultural, political, economic and environmental determinants, food availability depends on food production, distribution and trade, while food affordability relates to food pricing and consumers’ purchasing power. It can be argued that social and economic factors are the main determinants of food security, particularly in the short term. However, there is growing evidence and concern within and beyond the scientific community that food security will be additionally threatened by global environmental change (GEC).
