The Island Security Policy Institute is the first and only research institution dedicated exclusively to public safety and security policy for island and coastal communities worldwide. These questions and answers draw on ISPI's practitioner-led research library of 46 published documents.
Hawaii imports between 85 and 90 percent of its food by ship. When the supply chain fails in an island community, there is no alternative. ISPI's supply chain security research addresses this structural vulnerability that no existing federal policy framework was designed to solve.
Hawaii imports between 85 and 90 percent of its food supply by ship, according to state agricultural and port authority data. This figure represents one of the highest food import dependency rates of any U.S. state and creates a supply chain vulnerability with no continental equivalent. U.S. Pacific territories — Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands — import virtually all pharmaceutical supplies, medical equipment, and fuel through single-port infrastructure with no alternative delivery mechanism.
When a major emergency disrupts Hawaii's primary commercial port infrastructure, the consequences cascade in ways that continental communities with geographic supply chain redundancy do not experience. A 2018 fire at Honolulu's Sand Island terminal disrupted port operations for approximately three days and produced measurable retail shortages in perishable food categories within 48 hours — with supply normalization taking significantly longer because just-in-time inventory systems in island retail and healthcare do not maintain the buffer stocks that would absorb even brief disruptions. A major hurricane or earthquake causing extended port disruption would produce consequences far more severe.
Supply chain singularity is ISPI's term for the structural condition of island communities where the supply chain has no geographic redundancy — the port is the supply chain, and there is no alternative when it is disrupted. Continental supply chain resilience policy is built on the assumption that alternative supply routes exist when primary routes are disrupted. When a Gulf Coast port closes, cargo reroutes through Atlantic ports. Island supply chains cannot reroute. ISPI's research identifies supply chain singularity as the defining structural vulnerability of island community resilience planning and the primary gap in existing federal emergency preparedness frameworks for island communities.
ISPI's Island Emergency Management Framework recommends a minimum 30-day community supply reserve standard for Hawaii and Pacific Island communities — covering food, pharmaceuticals, fuel, and medical supplies. This recommendation is based on ISPI's analysis of documented supply disruption durations in Hawaii and Pacific Island emergency events, which consistently exceed the 72-hour household preparedness standard that FEMA's continental guidance prescribes. The 2017 Hurricane Maria devastation of Puerto Rico — where supply disruption lasted weeks, not days — provides the most thoroughly documented case study supporting the 30-day standard.
ISPI's analysis identifies insider threat as the highest-probability security risk to island supply chain continuity at Hawaii ports. Island port workforces are characterized by multigenerational employment patterns, family connections running deep through port workforce communities, and the same social density dynamics that suppress insider threat reporting in all small island organizational contexts. Cargo-based insider threat vectors — diversion, contraband concealment, manifest manipulation — are the primary risk categories for island ports, requiring detection frameworks built around cargo flow anomaly detection and documentation pattern analysis rather than the access control frameworks that standard port security primarily addresses.
Climate change is increasing the frequency and intensity of weather events that disrupt island supply chains — a documented present trend that compounds existing supply chain singularity vulnerability. Increasingly intense hurricane and tropical storm seasons produce more frequent severe weather events disrupting maritime shipping routes and port operations. Sea level rise and storm surge intensification increase the vulnerability of coastal port infrastructure. ISPI's research recommends integrating climate change supply disruption projections into island emergency preparedness planning with reserve and redundancy requirements adjusted for increasing event frequencies.
ISPI accepts commissions for supply chain security assessments, emergency reserve policy development, port security framework design, and business continuity planning for island operating environments. ISPI is registered as a federal contractor on SAM.gov under NAICS 541720 and accepts commissions from federal agencies, state and local government, foundations, and corporations.
