Caribbean coral reefs are in rapid decline and artificial reefs are increasingly often deployed to restore lost three-dimensional structure. The majority of artificial reefs and other marine infrastructure is built from concrete, with Ordinary Portland Cement (CEM I) as the most important ingredient. …

Shellfish are a healthy source of protein but more strict regulation for traditional shellfish fisheries and fluctuations in population size warrant a need for sustainable and more reliable alternatives. These alternatives can be, for example, the culturing of new species like hard clam (Mercenaria mercenaria). …

The die-off of the long-spined sea urchin Diadema antillarum in the 1980s highlighted its crucial role as a primary grazer in tropical western Atlantic coral reefs. However, natural recovery has been slow, exacerbated by a new die-off in 2022. Interest in actively restoring D. antillarum populations …

The Netherlands is dependent on artificial structures for water safety. In addition to water safety the artificial structures also provide habitat for different aquatic species. When designing artificial structures like dikes and breakwaters adjustments can be taken to increase species richness or stimulate …

That coral reefs are in decline worldwide, particularly in the Caribbean, will come as no surprise. This decades-long decline has reached a potential tipping point as the weight of the effects of climate change have come decidedly to bear on the planet’s most diverse marine ecosystem. Whether coral reefs …

Tropical western Atlantic reefs have gradually shifted from being dominated by corals to being mainly covered by macroalgae. The mass-mortality of the sea urchin Diadema antillarum in the 80s and the slow to non-existent recovery exacerbated this shift. Chemical cues associated with these reefs are expected …

Adaptive governance describes the purposeful collective actions to resist, adapt, or transform when faced with shocks. As governments are reluctant to intervene in informal settlements, community based organisations (CBOs) self-organize and take he lead. This study explores under what conditions CBOs …

A bottleneck in restoring self-sustaining beds of the European oyster (Ostrea edulis) is the successful development and settlement of larvae to bottom habitats. These processes are largely governed by temperature but a mechanistic understanding of larval performance across ecologically relevant temperatures …

''Heritage buildings are often subjected to loading conditions that they were not exposed to in their earlier life span. Induced earthquakes in non-seismic regions caused by energy exploitation activities, or strains in the ground that are caused by the climate changes, are new phenomena that alter the …

As the year passes, keeping themselves afloat has become more challenging for the Netherlands. Climate change and sea level rise are primary factors influencing the maintenance and reinforcement of the country's dikes system. Therefore, a new Delta Plan has been implemented to make the dikes system climate-proof …
