Coral reefs have suffered degradation due to anthropogenic activities for decades. The direct and indirect effects of overfishing and pollution from agriculture and land development have been the major drivers of coral reef decline over the past two centuries. More importantly, these threats to coral ...
Shifting the paradigm: identifying the goals of monitoring and assessment for coral reefs and a methodology to meet those goals If we are to ever halt coral-reef degradation and reverse the losses that have been set in motion, we must recognize “that existing institutions have ceased adequately...
Annual expected benefits from coral reefs for flood protection. Estimates of the effects of reefs on avoided flooding to land, people, exposed capital and damaged capital. The differences between scenarios with and without reefs are avoided damages or present benefits of reefs Full size image Fig. ...
of coral reefs prevents the 100-yr flood from growing by 23% (113 km2), avoiding flooding to 53,800 (62%) people, US$2.7 billion (90%) damage to buildings and US$2.6 billion (49%) in indirect economic effects. We estimate the hazard risk reduction benefits of US coral reefs...
While the effects of OA are ubiquitous, they are of particular concern for calcifying organisms such as scleractinian corals, which use carbonate ions to build their skeleton (Hofmann et al.2010). This potential for OA to reduce calcification in corals has identified coral reefs as one of the ...
Fig. 2. Results of survey looking at effects of top six threats to coral reefs (threat rating scale of 0–6, with 0=no threat and 6=extreme threat) on: (a) perceived threat rating, n=110, and (b) resource (budget) allocation to abate those threats, n=110. Time allocation varied ...
