The document discusses coastal resource management and sustainability. It defines coastal resources as the intersection of terrestrial and marine ecosystems, including beaches, coral reefs, mangrove forests, and coastal communities. These resources are important for marine sanctuaries, reef monitoring, mangrove reforestation, seaweed farming, and aquaculture. The document recommends both soft engineering approaches like mangrove planting, dune stabilization, coral growth, and beach nourishment as well as hard engineering through seawalls, breakwaters, groynes, and gabions to conserve these coastal areas for future generations.
