New publication drawing on SPACES data shows East African reefs particularly susceptible to coral bleaching
SPACES team members, Tim McClanahan and Nyawira Muthiga have used SPACES coral reef survey data in an analysis of the factors affecting coral’s susceptibility to coral bleaching in the face of warmer climates.
The analysis based on surveys from E. Africa to Fiji during the 2016 El Nino event showed that bleaching is caused by a range of stressors on reefs.
In terms of geography, the researchers found that bleaching depended greatly on where the corals lived along the longitudinal gradient from East Africa to Fiji. Worryingly for E. African coastal states, their reefs appeared to show the strongest bleaching response to heat stress.

How DO coastal ecosystems support human wellbeing? New SPACES publication on the many mechanisms
A new paper based on SPACES research reports the diverse ways people reported that ecosystem services support different aspects of wellbeing.
The paper discusses these using the capability approach and theory of human needs. The the diverse mechanisms to contribute to wellbeing can be categorised as money, use or experience. Considering all of these mechanisms can inform the development of interventions that aim to protect or improve flows of benefits to people.

New Publication: Assessing Basic Human Needs to prevent serious harm
The methodology used to explore whether people meet their basic human needs is presented and discussed in this new paper. The paper proposes this as a way to monitor the impact of conservation actions on people to prevent serious harm.

New Publication: Kenyan and Mozambican coral reef ‘carbonate budgets’ contribute to international picture of corals under sea-level rise.
SPACES coral reef surveys have contributed to an international picture of how reefs might be able to grow to keep up with sea-level rise, recently published in Nature.
The growth of coral reefs is strongly influenced by the amount and types of coral living on the reef surface, but across both regions this growth is now being hampered by combinations of coral disease, deteriorating water quality and fishing pressure, along with severe impacts from “coral bleaching” caused by climate change. By counting the organisms responsible for building up and eroding reefs, SPACES team members Chris Perry and Fraser Januchowski-Hartley have been able to calculate the ‘carbonate budget’ and estimate how quickly reefs can grow towards the surface (the ‘accretion rate’).
In the figure below, the Mozambican (17) and Kenyan (18) SPACES sites can be seen in comparison to reefs from around the Indian ocean and Western Atlantic. The poorest reefs in […]
