  • PUBLICATION NOTICE: Water Security Scenarios: Planning for Installation Water Disruptions

    Abstract: The Army’s critical missions are at risk from interruption of water supplies. Sufficient amounts of high- quality potable water are a resource without substitute. The Army’s Installation Energy and Water Security Policy establishes requirements for installations to sustain critical mission capabilities and to mitigate risks posed by energy and water disruptions that affect installations; this includes coordinating vulnerability and risk assessments of potential disruptions and implementing adequate responses to mitigate identified risks. Resilient installations will develop storage capacity to forestall water shortages and will also have short- and long-term plans to help the installation recover from events and forestall progressing to more severe deficits. This project supports compliance with the water security policy by exploring the range of conditions and responses possible across installations. Multiple scenarios were developed to explore how a 14-day interruption in water supply might affect an installation and to provide preliminary guidance to help installations develop strategies to address water disruptions to critical missions drawing from existing processes used in mission assurance. Researchers investigated types of installations and classes of scenarios most relevant to installation water security planning and explored several scenarios to provide a framework to helps installations advance their water resilience and security planning.
  • PUBLICATION NOTICE: Projecting Changes in Food Security Throughout Central America

    Abstract: Climate non-stationarity continues to change the productivity of local food and water supply. These changes in supplies could result in starvation or surpluses, greatly affecting the surrounding populations and causing adverse effects such as malnutrition, mass migration, and political unrest. This study addresses the following questions regarding the future potential of land resources to support local populations with food and water: How will crop production be affected by changing environmental conditions? Which specific regions are expected to experience the greatest pressure? How might we expect land use to shift through the end of the 21st century, based on future environmental conditions? Current crop growth is analyzed, along with projected crop growth based on future climate scenarios. Recent historic anthropogenic biome maps are statistically correlated with recent historic climate data to generate models and are applied to anticipated future climates to generate future anthrome maps. The crop analysis is then coupled with the anthromes results, yielding a crop suitability forecast. This analysis is constrained to the area of Central America over the course of the 21st century for this study.
