The study looked at 27 countries around the world and found two common characteristics: nations with low incomes that lack the ability to adapt to alternative protein sources; and middle-income nations with higher adaptive capacity but higher sensitivity to climate change.
According to the analysis, Indonesia and Liberia were the most vulnerable countries to fisheries declines from a food security perspective, while Malaysia and Sri Lanka were the least vulnerable.
The study, which appears in the November issue of the journal Environmental Science and Policy, is authored by Sara Hughes, Annie Yau, Lisa Max, Nada Petrovic, Frank Davenport, and Michael Marshall of the University of California; Tim McClanahan of the Wildlife Conservation Society; Edward Allison of WorldFish Center; and Josh Cinner of James Cook University.
The authors say the results of the study should be a wake-up call for nations to begin enacting policies to promote alternative protein sources, either through land-based means such as growing beans and poultry farming, or increased aquaculture. Coral reef fisheries are expected to decline with climate change and other human caused disturbances.
"The study identifies countries where climate change is likely to be felt first by threatening people that depend on fisheries," said the study's co-author Tim McClanahan of the Wildlife Conservation Society. "These countries are priorities for developing adaptation actions before the effects of climate change undermine their ability to feed themselves.
Some countries will be stressed by climate yet have enough capacity to make the adaptation, while others will not. Making them realize this early will save considerable human suffering in the future."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
