This technical session focused on research related to Environmental Security topics and the role being played now and potentially in the future in this research area. Environmental Security is that component of national security where environmental conditions may present challenges and opportunities within national security priorities; themes include, but are not limited to, food security, water security, energy security, economic development, infectious disease, and land use. This session explored the essential connections of physical science/engineering and the social sciences and how this research can influence DoD design, planning, and policy.
