Bij het Caribische eiland Saba wordt hard gewerkt aan een kunstmatig koraalrif. Het gaat slecht met het koraal en dit kunstmatige rif moet de biodiversiteit onder water weer op peil krijgen. Bevat geluidsfragment met telefonisch interview met Alwin Hylkema, onderzoeker aan het lectoraat Kust- en Zeemanagement …

The coral reef ecosystem provides important services such as tourism revenue, food, pharmaceutical products and coastal defence. Coral reefs are under a severe amount of threats such as pollution, overfishing and climate change. These threats result in a decrease of coral reefs and so a decrease in three- …

For multiple reasons, such as changing ocean temperatures, overfishing and unsustainable tourism coral reefs are declining worldwide. A negative feedback loop is created by the loss of three-dimensional structures that the coral reefs create. These three-dimensional structures provide shelters for grazing …

Coral reefs have been in decline over the past decades. This has greatly increased the need for restorative measures. The islands of Saba and St. Eustatius, two special Dutch municipalities in the Dutch Caribbean, are not exempt to this decline. The Saba Conservation Foundation and St. Eustatius National …

Coral reefs in the Caribbean have suffered massive losses of corals since the early 1980s due to a wide range of human impacts, such as explosive human populations growth, coastal pollution, global warming, overfishing, invasive species and diseases. The publication in the journal science in 2003 stated …

Coral reefs are one of the most important ecosystems in the world, in terms of both biological diversity and economy. These ecosystems are under a great amount of threats (e.g. climate change, pollution, coastal development and overfishing), which can lead to reef degradation and decrease of three-dimensional …

Als vissen niet meer terecht kunnen in koraalriffen, wat is dan het beste kunstmatige onderkomen dat wij mensen ze kunnen bieden? Alwin Hylkema, onderzoeker aan Hogeschool van Hall Larenstein in Leeuwarden, onderzoekt of, en zo ja welke, kunstmatige riffen een tijdelijke schuilplaats kunnen bieden voor …

The use of artificial reefs for purposes of ecosystem restoration and enhancement is gaining popularity due to recent declines of marine ecosystems. In particular the global decline of natural coral reefs and fish populations demands suitable approaches for improvement. However, is the availability of …
