Coral reefs and food security: Study shows nations at risk

18.10.2012
A new study co-authored by the Wildlife Conservation Society identifies countries most vulnerable to declining coral reef fisheries from a food-security perspective while providing a framework to plan for alternative protein sources needed to replace declining fisheries.

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."

The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. Visit www.wcs.org.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
