Lokale Bedrohungen verwalten

Die Kombination aus globalem Klimawandel und lokalen Bedrohungen hat zu einem starken Rückgang der Korallenriff-Ökosysteme weltweit geführt. Über 50 % der Korallen sind in den letzten 30 Jahren möglicherweise verloren gegangen. ref with a 14% decline in live coral cover observed just in the last 10 years. ref Corals are now listed as “most at risk of extinction” by the Convention on Biological Diversity, ref with catastrophic repercussions on the services they provide and the people they support, reflecting not just a biodiversity crisis, but also a social, cultural, and economic challenge.

Local and regional threats are often linked with human pressures and coast to reef processes. These threats may occur alone or synergistically with climate change adding to the risks to coral reef systems. However, local and regional threats often originate from sources that can be proactively managed to reduce and/or eliminate negative pressures to coral reefs.

In this toolkit we explore the most pervasive local threats and associated management strategies, including:

• Overfishing and destructive fishing
• Luftverschmutzung
• Küstenentwicklung
• Tourism and recreational impacts
• Korallenkrankheiten
• Invasive Arten
• Coral predator outbreaks
