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
