The authors say the vulnerability map will help governments, environmental agencies, and donors identify areas where to best invest in protected area establishment, restoration efforts, and other conservation activities so as to have the biggest return on investment in saving ecosystems and the services they provide to wildlife and people alike.
The map illustrates the global distribution of the climate stability/ecoregional intactness relationship. Ecoregions with both high climate stability and vegetation intactness are dark grey. Ecoregions with high climate stability but low levels of vegetation intactness are dark orange. Ecoregions with low climate stability but high vegetation intactness are dark green. Ecoregions that have both low climate stability and low levels of vegetation intactness are pale cream.
The study appears in an online version of the journal Nature Climate Change. The authors include: Dr James Watson of the Wildlife Conservation Society and the University of Queensland; Dr Takuya Iwamura of Stanford University; and Nathalie Butt of the University of Queensland.
"We need to realize that climate change is going to impact ecosystems both directly and indirectly in a variety of ways and we can't keep on assuming that all adaptation actions are suitable everywhere. The fact is there is only limited funds out there and we need to start to be clever in our investments in adaptation strategies around the world,," said Dr. James Watson, Director of WCS's Climate Change Program and lead author of the Nature study. "The analysis and map in this study is a means of bringing clarity to complicated decisions on where limited resources will do the most good."
The researchers argue that almost all climate change assessments to date are incomplete in that they assess how future climate change is going to impact landscapes and seascapes, without considering the fact that most of these landscapes have modified by human activities in different ways, making them more or less susceptible to climate change.
A vulnerability map produced in the study examines the relationship of two metrics: how intact an ecosystem is, and how stable the ecosystem is going to be under predictions of future climate change. The analysis creates a rating system with four general categories for the world's terrestrial regions, with management recommendations determined by the combination of factors.
Ecosystems with highly intact vegetation and high relative climate stability, for instance, are the best locations for future protected areas, as these have the best chance of retaining species. In contrast, ecosystems with low levels of vegetation and high relative climate stability could merit efforts at habitat restoration. Ecosystems with low levels of vegetation intactness and low climate stability would be most at risk and would require significant levels of investment to achieve conservation outcomes.
The new map, the authors say, identifies southern and southeastern Asia, western and central Europe, eastern South America, and southern Australia as some of the most vulnerable regions. The analysis differs from previous climate change exposure assessments based on only climate change exposure which shows the most vulnerable regions as central Africa, northern South America, and northern Australia.
"Effective conservation strategies must anticipate not only how species and habitats will cope with future climate change, but how humans will respond to these challenges," added Dr. John Robinson, Executive Vice President for Conservation and Science. "To that end, maintaining the integrity of the world's ecosystems will be the most important means of safeguarding the natural world and our own 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 http://www.wcs.org.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
