Global Water Security Defense Intelligence Agency

This report-requested by the Department of State-is designed to answer the question: How will water problems (shortages, poor water quality, or floods) impact US national security interests over the next 30 years? We selected 2040 as the endpoint of our research to consider longer-term impacts from growing populations, climate change, and continued economic development. However, we sometimes cite specific time frames (e.g., 2030, 2025) when reporting is based on these dates. For the Key Judgments, we emphasize impacts that will occur within the next 10 years.
