The paper introduces global resources challenges and their risks and shifts in what society defines as global securities. The paper will then introduce the water-energy-food nexus as a resource integration platform and will highlight green water as a hotspot in this nexus. Analysis will focus on the manner in which green water should be viewed as a resource base for food security. Discussions related to its regional integration into food security issues will be explored and the implications of climate change and externalities that affect water resources variability will be discussed. Nexus hotspot applications are introduced to highlight the use of the nexus as a holistic platform to address water, energy, and food resources. The paper closes with the presentation of recommendations for next steps.
