Coastal Development and Runoff

Hawaii’s coastlines continue to be developed for a variety of land uses. Agricultural lands that were once primarily used to grow sugarcane and pineapple are being converted to residential and resort uses across the state. Total acreage of sugarcane decreased almost 50% from 1995 to 2005 with 33,167 ha (81,957 acres) and 16,246 ha (40,145 acres) estimated respectively (State of Hawaii Data Book, 2005).
