Chapin, a professor at the Institute of Arctic Biology and member of the National Academy of Sciences, is the lead author in an interdisciplinary team of ecologists, anthropologists, an economist, a historian and a political scientist that published the recommendations in a recent issue of the scientific journal Proceedings of the National Academy of Sciences.
The authors identified Alaska as a particularly appropriate place to apply their strategies because ecosystem services such as water, food, and fuel, which are key processes that mediate climate effects on society, are critical to the sustainability of rural livelihoods and culture.
In Alaska, climate warming has triggered more intense and extensive wildfires, bark beetle outbreaks, lowered regional water tables, increased permafrost thaw and subsequent thermokarsts, which contribute to the failure of roads, homes and other infrastructure.
"We took stock of these changes and from that we assessed what society is going to need to respond to these changes," said Gary Kofinas, co-author and coordinator of the Resilience and Adaptation Program at UAF. The policy recommendations, Kofinas said, address "... what we need to do and what can we do to retain the properties of the social and ecological systems in which we live."
The first strategy focuses on enhancing humans' adaptability to a warming climate by integrating science and technology with local knowledge, and by integrating science, management and local needs using what the authors call adaptive management and governance.
The second strategy focuses on enhancing the resiliency of people and the environment to significant social and ecological change. By increasing biological, cultural, and economic diversity the authors argue that humans will have more options for adapting to changes and that such diversity can act as a buffer from change.
The third strategy focuses on reducing human and environmental vulnerability by effectively communicating to the public how the effects of high-latitude (Arctic) climate warming are linked to their low-latitude causes. "The climate change impacts being experienced in Alaska can be responded to here, but most of their causes need to be addressed at the national or international level," said co-author Martin Robards, a UAF RAP Ph.D. student. Reducing the anthropogenic (human-caused) contribution to climate warming - greenhouse gas emissions - is the key to mitigating climate change-related vulnerability in Interior Alaska," write the authors.
The fourth strategy is to facilitate transformation. "People typically prefer to adopt an accustomed life, rather than perpetually adapting to sudden and rapid changes," Robards said. "Transformation is the ability of people to look at the changing world and their place in it in new and unknown ways." For example, rising oil prices makes transforming an Alaska village from diesel-based fuel to biomass more feasible.
Despite the challenges of sustaining the beneficial attributes of complex social-ecological systems in the face of multiple large-scale directional changes, including climate warming, the authors conclude that each of the strategies provides societal benefits and suggest that all be pursued simultaneously.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
