With global population expected to reach 9 billion by 2050, and the development of urban areas extending into agricultural lands to support growing numbers of residents, there is pressure on the world’s food systems to produce food on less land with greater efficiency (Godfray et al., 2010). In addition to increasing urban developments, productive agricultural land is being lost due to environmental degradation caused by unstainable crop production practices, and more recently as a result of climate change (IPCC, 2007; Schmidhuber and Tubiello, 2007). Furthermore, food production from the oceans has been drastically reduced, with most fisheries being exploited at unsustainable rates (Pauly et al. 2003, Myers and Worm 2003, Worm et al. 2006, Worm et al. 2009). Along with overfishing, rising sea temperatures and ocean acidification resulting from climate change are expected to greatly reduce coral reef fisheries in the Pacific, the main food source for many communities, 20% by 2050 (Keener et al. 2012, Bell et al. 2013, Hooidonk et al. 2013). The competing issues of food security, residential and commercial development, and climate change are especially compelling in Hawaiʻi because it is an island ecosystem over 2,000 miles from the continental U.S., and has an immense dependency on imported goods. A recent study by Loke and Leung (2013) found that the vast majority (88.4%) of food consumed in Hawaiʻi, was imported, and estimated that the percentage of food locally…
