Challenges to Global Food Security


Global food security, providing access for the world’s population to affordable, safe and nutritious food, is one of the major challenges of the 21st century.


This module will provide an understanding of the elements that contribute to the food security agenda. An essential element of the module will be a critical review of current physical, political and biotic drivers. We will explore the strategies being deployed that influence food security including projected population changes, climate change, ecosystem servicers and resilience, disease and fossil fuel dependence. The module will present a global perspective.
