Abstract. The insurance of green economy assets against natural hazards is a growing market. This study explores whether currently available published knowledge adequate for the vulnerability assessment these to hazards. A matrix constructed demonstrate functional loss 37 asset classes in renewable energy, construction, resource management, carbon capture and storage, energy sustainable transportation sectors. 28 adopted range from environmental geophysical events oceanic, coastal, space weather events. fundamental challenge constructing was lack an asset–hazard taxonomy economy. Each cell represents specific hazard, based on comprehensive systematic literature review. confidence level assigned each density heat map. latter highlights gaps, particular quantitative studies that appropriately represent all mechanisms assets. Apart charting research main output this proposal representative guide future can be applied by industry.

Patterns and implications of spatial covariation in herbivore functions on resilience of coral reefs

Abstract Persistent shifts to undesired ecological states, such as from coral macroalgae, are becoming more common. This highlights the need understand processes that can help restore affected ecosystems. Herbivory on reefs is widely recognized a key interaction keep macroalgae outcompeting coral. Most attention has been role ‘grazing’ herbivores play in preventing establishment of while less research focused ‘browsers’ extirpating macroalgae. Here we explored patterns, environmental correlates and state shift consequences spatial co-variation grazing browsing functions herbivorous fishes. Grazing rates were not highly correlated across 20 lagoon sites Moorea, French Polynesia, but did cluster into 3 (of 4) combinations high low consumption (no site had browsing). Consumption with grazer or browser fish biomass, both predicted by specific variables. Experiments revealed reversibility macroalgal was strongly related variation intensity. Our findings provide insights simple diagnostic tools regarding heterogeneity top-down forcing influences vulnerability reefs.

Securing ecosystem functions is challenging, yet common priority in conservation efforts. While marine parks aim to meet this challenge by regulating fishing through zoning plans, their effectiveness hinges on compliance levels and may respond changes practices. Here we use a speciose assemblage of nominally herbivorous reef fish Karimunjawa National Park (zoned since 1989) investigate whether areas subject restrictive management regime sustained higher biomass over seven years compared where moderate permissive regulations apply. Using trait-based approach characterize the functional space entire species pool ask translate into structure. We track predator biomass, benthic community structure, practices that could influence herbivore trajectories. Overall doubled 2012 2006-2009 remained high 2013 across all regimes. found no evidence build-up resulted from depletion or increased food availability but suggest it emerged response park-wide cessation with large drive nets known as muroami. The increase was accompanied modest taxonomic richness slight decrease community-scale rarity did not alter redundancy levels. Subtle both specialization identity assemblages generalist low intrinsic vulnerability recovered sooner than more vulnerable specialists. implies recovery mechanisms responsible for grazing algal turfs detritus, restoring other facets herbivory (e.g., macroalgal consumption) require time. An cost-benefit ratio per journey muroami facilitated ban met minimal resistance. Similar windows opportunity emerge elsewhere which gear-based can supplement especially when low. This does advocate implementing such once fishery has become unprofitable. Rather, underlines importance breaking cycle resource zoning, thus alleviating resulting threats security integrity.
