This policy gap analysis identifies threats to coral reefs, evaluates the effectiveness of the existing legal framework to address these threats, and formulates recommendations to strengthen community-based natural resource management in Solomon Islands. Coral reefs are of crucial importance for food security and rural livelihoods in the archipelago. Logging is a major, yet often overlooked, threat to coral reefs in the country. Large-scale logging operations cause massive erosion, which has a detrimental effect on water quality.

While coral reefs become increasingly degraded, new techniques are increasingly needed to assist reefs in recovering and adapting to changing environmental conditions. The urgent motivation to sustain coral reefs has fueled a building momentum to restore and rebuild reefs, with increasing numbers of projects, research studies, and investments. Coral reef restoration is a burgeoning new field with much potential, and the authors of this Guide are excited to contribute to this global effort.

The Global Reef Expedition: The Kingdom of Palau Final Report provides a summary of the foundation’s findings along with valuable information on the state of coral reefs and reef fish in Palau.

Well-managed and enforced no-take marine reserves generate important larval subsidies to neighboring habitats and thereby contribute to the long-term sustainability of fisheries. However, larval dispersal patterns are variable, which leads to temporal fluctuations in the contribution of a single reserve to the replenishment of local populations. Identifying management strategies that mitigate the uncertainty in larval supply will help ensure the stability of recruitment dynamics and minimize the volatility in fishery catches.

This summary provides resorts, tourism operators, and policy makers with an introduction to marine conservation agreements (MCA) and outlines a process for planning and implementing an MCA in Fiji.

Sea surface temperature, determined remotely by satellite (SSST), measures only the thin “skin” of the ocean but is widely used to quantify the thermal regimes on coral reefs across the globe. In situ measurements of temperature complements global satellite sea surface temperature with more accurate measurements at specific locations/depths on reefs and more detailed data. In 1999, an in situ temperature-monitoring network was started in the Republic of Palau after the 1998 coral bleaching event.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision making. Here we combine engineering, ecologic, geospatial, social, and economic tools to provide a rigorous valuation of the coastal protection benefits of all U.S.

In recent decades, despite their value, coral reefs have been endangered and are swiftly declining because of land overuse, rising sea temperatures, and increasing ocean acidification. This study assesses the willingness to pay (WTP) for coral reef conservation in Japan. We conducted an online discrete choice experiment with 10,573 respondents. A latent class logit model framework was used, and three respondent classes were recognized.

Feeding wild animals is a regular habit in ecotourism worldwide with poorly known consequences for ecosystem functioning. This study investigates how effective bread feeding is at attracting coral reef fish in the South Pacific, which feeding groups of fish are most attracted, and how natural foraging rates of an omnivorous and a grazingdetritivorous fish are affected. Data were collected at sites where fish are regularly fed bread by snorkellers and at comparison sites where bread was only provided for this study, within the Aitutaki lagoon (Cook Islands).

On the Global Reef Expedition—one of the largest coral reef studies in history—the Khaled bin Sultan Living Oceans Foundation conducted research in the Solomon Islands to map and characterize shallow marine habitats and assess the status of coral reef benthic and fish communities. Working in partnership with local officials and scientists from around the world, the Foundation surveyed reefs in the Western, Isabel, and Temotu Provinces from October 26 through November 24, 2014.
