Management Approaches

Across the Pacific Islands, declining natural resources have contributed to a cultural renaissance of customary ridge-to-reef management approaches. These indigenous and community conserved areas (ICCA) are initiated by local communities to protect natural resources through customary laws. To support these efforts, managers require scientific tools that track land-sea linkages and evaluate how local management scenarios affect coral reefs. We established an interdisciplinary process and modeling framework to inform ridge-to-reef management in Hawai‘i, given increasing coastal development, fishing and climate change related impacts. We applied our framework at opposite ends of the Hawaiian Archipelago, in Hā‘ena and Ka‘ūpūlehu, where local communities have implemented customary resource management approaches through government-recognized processes to perpetuate traditional food systems and cultural practices. We identified coral reefs vulnerable to groundwater-based nutrients and linked them to areas on land, where appropriate management of human-derived nutrients could prevent increases in benthic algae and promote coral recovery from bleaching. Our results demonstrate the value of interdisciplinary collaborations among researchers, managers and community members. We discuss the lessons learned from our culturally-grounded, inclusive research process and highlight critical aspects of collaboration necessary to develop tools that can inform placed-based solutions to local environmental threats and foster coral reef resilience.

In Palawan, Philippines, Honda Bay is fast becoming a target recreational site for curious domestic and foreign visitors. The general objectives of this resource assessment are to gather information regarding status of the marine resources in Pandan Island, and to provide recommendations for their sustainable use. Assessment was done using line intercept transect (LIT), fish visual census (FVC) and an imaginary transect belt for coral cover, fish, and macro-invertebrates, respectively. Average live coral cover around Pandan Island can be categorized as good (57%), with stations 7 and 1 and 2 categorized as excellent (76-100%) and fair (26-50%) conditions, respectively. Some 178 fish species were recorded in Pandan Island waters of which seven (7) highly target and 29 common commercial fish species were found. The estimated total reef fish biomass around Pandan Island is 588 mt/ km2. A total of eight macro invertebrate (shells, etc.) species belonging to five families was found around Pandan Island. The study concluded that of these eight species, six are commercially important,Tridacnacro cea(taklobo), Tridacnasquamosa (taklobo), Hippopusporcellanus(taklobo), Trochusniloticus(topshell), Pinna nobilis (tarab), and Bohadschiamarmota (sea cucumber). Five of these species the T. crocea, T. squamosa, H. porcellanus, P. nobilis, and T. niloticus are listed as endangered species by International Union for Conservation of Nature.   Keywords - target species, macro-invertebrates, coral cover, coral reefs, reef fish, conservation

Seawater Ph

Ocean acidification (OA) is impairing the construction of coral reefs while simultaneously accelerating their breakdown. The metabolism of different reef organism assemblages alters seawater pH in different ways, possibly buffering or exacerbating OA impacts. In spite of this, field data relating benthic community structure and seawater pH are sparse. We collected pH time-series data snapshots at 10 m depth from 28 different reefs (n = 13 lagoon, n = 15 fore reef) across 22 Pacific islands, spanning 31° latitude and 90° longitude. Coincident with all deployments, we measured percent cover of the benthic community. On fore reefs, high coral cover (CC) negatively correlated with mean and minimum pH, but positively correlated with pH variability. Conversely, pH minima were positively correlated to coverage of coralline and turf algae. Benthic cover did not correlate with pH in lagoonal reefs. From 0%–100% CC, mean pH and aragonite saturation state (Ωarag ) declined −0.081 and −0.51, respectively, while declines in minimum values were greater (Δmin pH = −0.164, Δmin Ωarag = −0.96). Based upon previously published relationships, the mean pH decline from 0%–100% CC would depress coral calcification 7.7%–18.0% and increase biologically-mediated dissolution 13.5%–27.9%, with pH minima depressing dark coral calcification 14.4%–35.2% and increasing biologically-mediated dissolution 31.0%–62.2%. This spatially expansive dataset provides evidence that coral reefs with the highest coral cover may experience the lowest and most extreme pH values with OA.

The islands of Pacific Oceania face unprecedented anthropogenic climate change within this century. Rising sea levels, increasing ocean acidification, warming land and sea temperatures, increasing droughts, and changes in the frequency and intensity of storms are likely to reorder or destroy ecosystems such as coral reefs, mangrove and montane forests, and coastal wetlands. For the developed nations, an array of measures could ameliorate these effects. Developing nations, whose economies may be significantly damaged by climate change, face major impacts on their citizens, identifying conservation of biodiversity as a lesser priority. Conservation in these countries may not succeed unless the rich nations are willing to pay for preservation of biodiversity hotspots or where preservation of biodiversity satisfies the needs of local communities, often through traditional management and land tenure systems in rural areas. These communities will need useable information, as well as technical advice on how to reduce stressors on changing ecosystems such as wetlands, mangrove forests and coral reefs, if they are going to achieve conservation. The resulting process if it involves local people may appear inefficient, relative to international expectations, but will be more effective over a wide area in conserving biodiversity.

Sustainable Development And Management

This article discusses the challenges facing the Pacific region in implementing the Pacific Islands Regional Ocean Policy (PIROP), which aims to ensure sustainable use of the Pacific Ocean’s resources for the future. The author outlines some of the particular issues confronting Pacific Island countries, and the need for a more collaborative approach to ocean management.The five guiding principles of PIROP are then discussed in turn. These include: improving our understanding of the ocean; the sustainable development and management of the ocean’s resources; maintaining the health of the ocean; promoting the peaceful use of the ocean; and creating partnerships and promoting cooperation. Issues such as the protection of traditional knowledge in relation to the ocean, and the need to preserve the integrity of the Pacific’s ecosystems, are highlighted.
