CHDS State/Local / Approved for public release, distribution is unlimited / To defend American agriculture against foreign or domestic terrorism, it is essential that states build multi-state partnerships to provide for the collaborative plans, programs and operations needed to protect the nations food security. The National Homeland Security Strategy puts states on the front lines in the war against terrorism---including the struggle to secure the agriculture industry from potentially devastating attack. The issues surrounding agro-terrorism are vast and complex and the resources of the Federal government to address these issues are limited and overextended. If states attempt to address this threat independently, important opportunities to reduce vulnerability and enhance capability will be lost. To achieve the capabilities needed for agro terrorism detection, mitigation, preparedness and response, states must collaborate to build the partnerships and programs their citizens require. This thesis argues multi-state partnerships are critical to defeating this threat as well as providing a robust response to an attack. Whether intentionally introduced or naturally occurring , infectious diseases can easily cross state borders before an outbreak is even detected. States must be prepared to act quickly to mitigate the effects of any crisis. There is a significant opportunity for states to strengthen their abilities to provide for a stronger agriculture counter terrorism preparedness system. The states can further their ability to combat attacks on agriculture actively by demonstrating leadership in implementing administrative agreements and ultimately adopting compact(s) between states as well as with the private sector. / Civilian, Homeland Security Advisor and Emergency Management Administrator, Iowa Homeland Security and Emergency Management Division
