28 January 2016, Science Daily, Intact nature offers best defense against climate change. Worldwide responses to climate change could leave people worse off in the future according to a recent study conducted by CSIRO, Wildlife Conservation Society (WCS) and the University of Queensland. The paper, “Intact ecosystems provide the best defense against climate change,” published in Nature Climate Change, discusses how certain adaptation strategies may have a negative impact on nature which in turn will impact people in the long-term. “In response to climate change, many local communities around the world are rapidly adjusting their livelihood practices to cope with climate change, sometimes with catastrophic implications for nature,” according to CSIRO’s principal research scientist Dr. Tara Martin. The authors say that in Australia and Canada, conservation reserves are being used as drought relief to feed livestock, while forests in the Congo Basin in Africa are being cleared for agriculture in response to drought, and coral reefs are being destroyed to build sea walls from the low-lying islands in Melanesia. Dr. Martin added: “These are just few of the human responses to climate change that, if left unchallenged, may leave us worse off in the future due to their impacts on nature. Functioning and intact, forests, grasslands, wetlands and coral reefs represent our greatest protection against floods and storms.” The paper states that intact native forests have been shown to reduce the frequency and severity of floods, while coral reefs can reduce wave energy by an average of 97 per cent, providing a more cost-effective defense from storm surges than engineered structures.
