7 September 2015, The Conversation, Restoring and conserving nature in the Anthropocene means changing our idea of success. The Earth has unofficially entered a new epoch – the Anthropocene. It suggests that humans are the dominant influence on the planet’s ecosystems and biosphere – the sum total of life and non-living material on Earth. Many ecosystems have changed so radically that it is no longer possible to restore them to what they once were, and in other situations it is not appropriate. Instead we need to look at what we can change, accept the things we can’t, and recognise that humans are now an important part of nature. Restore, reclaim, reintroduce? Accepting humans as part of nature will require a shift away from traditional views of restoration and conservation. Governments and communities worldwide spend enormous sums of money and countless hours of work on restoration projects, aiming to reverse the degradation that we have wrought over the past few centuries. The United Nations, for example, has agreed to a target of restoring 150 million hectares of land by 2020, costing about US$18 billion each year. In Australia, federal and state governments have several very large restoration programs targeting, in one case, the Murray-Darling Basin – to protect and restore the degraded flowing waters and wetlands of our most iconic river system – and, in another, the Great Barrier Reef – to maintain and restore the universal value of our most iconic marine ecosystem. There is an elephant in the room. In most cases, restoration efforts aim to return ecosystems to a state closer to what they looked like in the past and how they functioned before modern society. This target is often termed an “historical baseline” . Read More here
28 August 2015, The Guardian, Extreme Arctic sea ice melt forces thousands of walruses ashore in Alaska. Survival of walruses threatened as they wash ashore on a remote barrier island just before Obama is due to visit region to draw attention to climate change. The extreme loss of Arctic sea ice due to climate change is forcing thousands of walruses to crowd ashore on a remote barrier island off Alaska, and threatening their survival. Barack Obama will be the first US president to visit the Alaskan Arctic on 31 August on a three-day tour to draw attention to the drastic consequences of climate change for the Arctic, such as warming winters and the rapid retreat of sea ice. The first reported sighting of animals forced to come ashore in the Chukchi Sea was by a photographer on 23 August, and confirmed by villagers in the remote hamlet of Point Lay late on Thursday, the US Fish and Wildlife Service said. Such landings, forced by the absence of sea ice on which to rest and feed, put the animals at risk of stampede in the limited space of the barrier island. The animals are easily spooked by aircraft or onlookers, government scientists warned. Trampling deaths are one of the biggest natural risks. Sea ice cover in the winter months fell to a new low this year because of climate change and abnormal weather patterns. Read More here
