In an article in Current Biology, Dr Richard Unsworth from the University’s College of Science, has revealed that people are relying on coral reefs less for their livelihoods as the reefs are increasingly under threat and facing an uncertain future due to increasing rates of climate change and rising global temperatures.
Instead, the article shows that people are looking to seagrass meadows as a means for fisheries support, but this is putting these habitats under increasing threat around the world. There is now an urgent need to broaden the focus of tropical marine conservation. Although seagrass is globally widespread, there is evidence of rising levels of degradation due to local water problems and physical disturbance, but these are factors that can be managed at local scales. Unsworth said “With the right support there can be a brighter future for seagrass”.
While the decline of coral reefs has garnered a great deal of attention and conservation efforts, Dr Unsworth says that the time is right for the tropical marine conservation community broadened its focus and become more realistic. Conservation efforts, it is argued, can no longer afford to focus exclusively on coral reefs but need to also safeguard seagrass into the future. There is an increasing focus on costly fanciful ideas to save coral reefs, but no recognition of thinking across the broader tropical marine seascape to rationalise where resources could be more efficiently focussed.
Dr Unsworth said: “Governments, NGOs and communities need to increase and reprioritise conservation efforts and use their limited conservation resources in a more targeted manner in order to attain sustainable systems. For seagrass, there are practicable conservation opportunities to develop sustainable ways to respond to increased resource use. Targeted action now could restore and protect seagrass meadows to maintain and many ecosystem functions they provide.”
